Résumé
Abstract Introduction: Even though only a few species are considered to be dangerous, pests or vectors, the majority of invertebrates produce a feeling of aversion in humans. This has contributed to the delay in the development of ethical considerations as regards this group in contrast with vertebrates, with the exception of cephalopods. Objective: In the present study, we provide an overview of the current situation on animal ethics and welfare in order to contribute to the development of a framework for ensuring invertebrate welfare. Methods: Today, animal welfare is multidisciplinary in nature to a very high degree as it includes ethology, physiology, pathology, biochemistry, genetics, immunology, nutrition, cognitive-neural, veterinary medicine, and ethics. Animal welfare is a complex concept, difficult to achieve successfully from one perspective. Results: As a consequence, we propose to include the five domains (nutrition, environment, health, behaviour and mental state) along with the three conceptions (basic health and functioning, affective state and natural living), as well as the 5R Principle (Replace, Reduction, Refinement, Respect and Responsibility) in seeking to achieve a comprehensive welfare state. Conclusions: We consider that in both research and animal production, the individual and collective ethical concerns coexist and, in fact, the main moral concern to account for is the collective one and that, within that collective view, the individual moral concern should be applied with responsibility and respect for the individual. Finally, we propose a practical example of invertebrate welfare production in sea urchin aquaculture with the aim of including animal production of invertebrates in this important discussion.
Resumen Introducción: Aunque sólo unas pocas especies son consideradas peligrosas, plagas o vectores, la mayoría de los invertebrados producen un sentimiento de aversión en el ser humano. Esto ha contribuido al retraso en el desarrollo de consideraciones éticas respecto a este grupo en comparación con los vertebrados, a excepción de los cefalópodos. Objetivo: En el presente trabajo, proporcionamos una visión general de la situación actual en materia de ética y bienestar animal con el fin de contribuir al desarrollo de un marco para garantizar el bienestar de los invertebrados. Métodos: Hoy en día, el bienestar animal es de naturaleza multidisciplinaria en un grado muy alto, ya que incluye etología, fisiología, patología, bioquímica, genética, inmunología, nutrición, cognitivo-neural, medicina veterinaria y ética. El bienestar animal es un concepto complejo, difícil de lograr con éxito desde una sola perspectiva. Resultados: Como consecuencia, proponemos incluir los cinco dominios (nutrición, ambiente, salud, comportamiento y estado mental) junto con las tres concepciones (Salud básica y funcionamiento, estado afectivo y vida natural), así como el Principio 5R (Reemplazar, Reducir, Refinar, Respetar y Responsabilidad) en la búsqueda de alcanzar un estado de bienestar integral. Conclusiones: Consideramos que tanto en la investigación como en la producción animal coexisten las preocupaciones éticas individuales y colectivas y, de hecho, la principal preocupación moral a dar cuenta es la colectiva y que, dentro de esa visión colectiva, se debe aplicar la preocupación moral individual. con responsabilidad y respeto por la persona. Finalmente, proponemos un ejemplo práctico de producción de bienestar de invertebrados en la acuicultura de erizos de mar con el objetivo de incluir la producción animal de invertebrados en esta importante discusión.

Objective:To investigate the application effect of production-oriented approach (POA) for consulting ability teaching in general practice standardized residency training.Methods:Eighteen third-year general practice residents in the Second Affiliated Hospital of Harbin Medical University received a special training course on the consulting ability based on POA with the situational simulation teaching from September 2021 to March 2022. The consulting ability of residents was evaluated with Objective Structured Clinical Examination (OSCE) and Leichester Assessment Package (LAP) before and after the training, and the results were compared. Meanwhile, a questionnaire survey and semi-structured interviews were conducted to assess residents′ satisfaction with the course.Results:All 18 resident trainees (11 females and 7 males) aged 25 to 34 (27.3±2.4) years successfully completed the training. Both OSCE scores and LAP scores after the training were significantly higher than those before training (66.25±5.84 vs. 44.44±12.80, t=8.46, P<0.001; 65.78±7.05 vs. 38.33±14.2, t=1.47, P<0.001, respectively). The ability of medical history collection, physical examination, patient management, problem solving, doctor-patient relationship, preventive care and medical record writing were all significantly improved after the training compared with those before training ( t=2.464, 4.278, 8.997, 2.385, 10.35, 5.212, 7.578, all P<0.05). The questionnaire survey showed that all the 18 residents were satisfied with the reasonableness of the teaching content, the class time arrangement, the teaching progress arrangement and the instructors. In the dimension of training effectiveness, 18 participants all believed that the course was helpful to improve their humanistic quality and confidence in reception. In terms of self-promotion, all respondents believed that this course was able to promote their reflection ability and stimulate their learning interest. By coding and analyzing the contents of the semi-structured interviews with the residents, nine main themes were constructed, namely course deficiencies, course characteristics, course advantages, course suggestions, trainees′ deficiencies, trainees′ gains, trainees′ goals, previous teaching deficiencies, and instructor′s role. The results showed that all residents had a high degree of satisfaction with the course, and they thought the course was vivid and interesting and it is able to mobilize the enthusiasm of learning, promote learner to reflect. The residents also suggested to increase the teaching hours and to enrich teaching cases. Conclusion:The consulting ability training of general practice based on POA can effectively improve consulting ability, stimulate learning interest and improve independent learning ability of residents, which gains recognition from both faculty and trainees.
Résumé
Aims@#The aim of this study was to cultivate the fungus Aspergillus tubingensis (MO503), which was isolated and identified from Algerian soil using submerged fermentation. The focus was on the production of lipase, achieved through utilizing a minimal medium from agro-food industries. Specifically, the study investigated the potential of three waste sources – olive-pomace, Pistacia lentiscus fruit remains and olive mill wastewater as substrates for enhancing lipase production. @*Methodology and results@#The three aforementioned wastes were chosen to ascertain their value and determine the most cost-effective option. Factorial analysis of variance (ANOVA) was employed to evaluate the waste with a significant effect on lipase production, as this enables determining differences among the various waste sources. Growth monitoring revealed a maximum lipase activity of 1030 ± 0,039 U at pH 5.4 for olive pomace. A series of biochemical purification techniques displayed a visible band on the polyacrylamide gel obtained through SDS-PAGE. Lipolytic activity was evidenced by zymography in the presence of olive oil. The antibacterial activities of purified lipase exhibited a high sensitivity against Gram-negative bacteria compared to Gram-positive bacteria. @*Conclusion, significance and impact of study@#In addition to its activity against Gram-negative bacteria, the lipid degradation facilitated by these lipases in olive oil offers promising applications in the textile and therapeutic industries.

Aims@#The microbiological qualities of fermented oil bean seeds depend on the indigenous microflora, personal and environmental hygiene of the handlers and the food environments. This study was aimed to evaluate the incidence of histamine-producing, multi-drug-resistant Enterococcus isolates from oil bean seeds during fermentation. @*Methodology and results@#Histamine extraction and analysis were performed on randomly sampled oil bean seeds. Histamine producing lactic acid bacteria (LAB) were isolated, from where Enterococcus species were further isolated. Strain-specific identification and antibiotic sensitivity tests were carried out on the identified Enterococcus isolates. Histamine was detected in fermented seeds. Enterococcus strains were identified among the histamine-producing fermenters. These include E. faecalis HA5, E. faecium VB976, E. faecium LMEM18, E. gallinarum M190262 and E. gilvus CR1. Enterococcus faecalis HA5, E. faecium VB976, E. faecium LMEM18, E. gallinarum M190262 and E. gallinarum were resistant to Ampiclox, Amoxicillin, Ceftriaxone, Ciprofloxacin and Erythromycin. Enterococcus faecium VB976, E. faecium LMEM18 and E. gallinarum M190262 were resistant to Streptomycin and Gentamycin. Enterococcus faecalis HA5 was intermediately resistant to Streptomycin and Gentamycin but sensitive to Vancomycin, while E. gilvus was intermediately resistant to Ampiclox, Amoxicillin and Gentamycin but sensitive to Ceftriaxone, Vancomycin, Ciprofloxacin, Streptomycin and Erythromycin.@*Conclusion, significance and impact of study@#The pathogenic and histamine-producing abilities of Enterococcus pose serious public health hazard. This is complicated by their resistance to a wide range of antibiotics. Therefore, improving the hygienic practices and regulating fermentation conditions is essential to curtailing histamine production and growth of fermenters with pathogenic potentials and ensuring the safety of the product.

ObjectiveBased on the experience of traditional quality evaluation, the quality of Atractylodis Macrocephalae Rhizoma(AMR) with different production methods such as direct seeding, transplanting after seedling raising, topping and non-topping, and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining, and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides, oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography(UPLC), and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA). ResultIn terms of traits, the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck, strong sweetness and clear aroma" recorded in ancient materia medica, followed by the 3-year-old AMR with topping after transplanting, while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect, the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang, the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition, the contents of 70% ethanol extract, fructose, glucose, sucrose, 1-kestose, atractylenolide Ⅰ, chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples(P<0.05). The contents of cellulose, 70% ethanol extract, sucrose, atractylenolide Ⅰ, atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate(P<0.05), while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting, direct seeding and without topping(P<0.05). ConclusionUnder the current mainstream production mode, too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield, but the accumulation of sweet substances, fragrant substances and fiber substances is insufficient, which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it, it is suggested to revise the quality standard of AMR, supplement the quantitative analysis of secondary metabolites, and strengthen the production of imitation wild AMR.

The development and application of processing technology is closely related to the quality of Chinese medicine. Currently, Chinese medicine processing is still in the mechanization stage with limited processing equipment, low levels of automation and intelligence. As a result, the imprecise control of parameters during processing leads to unstable quality of Chinese herbal pieces. However, with the arrival of the big data era and the continuous development of "Internet+", Chinese medicine processing technology and equipment have been continuously improved and updated, and gradually shifted to the development direction of automation and intelligence. The linkage production technology of Chinese herbal pieces optimizes the separate processing equipment coupling into the production line for continuous manufacture of Chinese herbal pieces, intending to improve production efficiency. The large-scale industrialized production of Chinese herbal pieces tends towards digital technology of processing experience and online inspection technology based on machine vision, electronic nose, and electronic tongue. These technologies are crucial prerequisites for standardizing the parameters of Chinese medicine processing. And further by docking the processing process and equipment with the internet, realizing the intelligent control of the production process is an important process for the transformation and upgrading of Chinese herbal piece industry in the future. In this paper, we summarized the development characteristics of different stages of Chinese medicine processing technology, combed application and development of processing theory, the evolution of processing equipment, and problems in the current industrial development stage of Chinese medicine processing, in order to provide ideas and methods for achieving digital and intelligent innovation of processing technology as well as high-efficient and high-quality production of Chinese herbal pieces.

This paper summarized PENG Qinghua's clinical experience in treating dry eye by applying therapeutic method of maintaining with sweet medicinals and restoring the body fluids. It is believed that the spleen earth insufficiency and fluids damage transforming into dryness are the main pathogenesis of the disease, and the basic therapeutic principle is maintaining with the sweet and restoring the body fluids by mainly using sweet medicines. It is advocated to use mild-sweet herbs, such as Baibiandou (Lablab purpureus subsp. purpureus), Fuling (Smilax glabra Roxb.), and Yiyiren (Coix lacryma-jobi L.), to transport spleen earth, so that qi is restored and body fluids are recovered; moderate-sweet herbs, such as Dangshen (Codonopsis pilosula [Franch.] Nannf.), Taizishen (Pseudostellaria heterophylla [Miq.] Pax), Shanyao (Dioscorea oppositifolia L.) and Zhigancao (Glycyrrhiza glabra L.) are suggested to cultivate earth and generate metal, so as to move qi and circulate fluid; sweet-cool herbs, such as Nanshashen (Adenophora triphylla [Thunb.] A.DC.), Beishashen (Glehnia littoralis [A.Gray] F.Schmidt ex Miq.), Yuzhu (Polygonatum odoratum [Mill.] Druce), Tianhuafen (Trichosanthes kirilowii Maxim.) are suggested to nourish yin and increase body fluids, so as to promote fluid production to moisten dryness. In this way, when the source of fluid is restored and the fluid is circulated, the fluid can be produced continuously, which provides new ideas for the treatment of dry eyes with traditional Chinese medicine.
Résumé
Solute carriers (SLCs) constitute the largest superfamily of membrane transporter proteins. These transporters, present in various SLC families, play a vital role in energy metabolism by facilitating the transport of diverse substances, including glucose, fatty acids, amino acids, nucleotides, and ions. They actively participate in the regulation of glucose metabolism at various steps, such as glucose uptake (e.g., SLC2A4/GLUT4), glucose reabsorption (e.g., SLC5A2/SGLT2), thermogenesis (e.g., SLC25A7/UCP-1), and ATP production (e.g., SLC25A4/ANT1 and SLC25A5/ANT2). The activities of these transporters contribute to the pathogenesis of type 2 diabetes mellitus (T2DM). Notably, SLC5A2 has emerged as a valid drug target for T2DM due to its role in renal glucose reabsorption, leading to groundbreaking advancements in diabetes drug discovery. Alongside SLC5A2, multiple families of SLC transporters involved in the regulation of glucose homeostasis hold potential applications for T2DM therapy. SLCs also impact drug metabolism of diabetic medicines through gene polymorphisms, such as rosiglitazone (SLCO1B1/OATP1B1) and metformin (SLC22A1-3/OCT1-3 and SLC47A1, 2/MATE1, 2). By consolidating insights into the biological activities and clinical relevance of SLC transporters in T2DM, this review offers a comprehensive update on their roles in controlling glucose metabolism as potential drug targets.

Through the herbal textual research, It can be verified that, since the Qing dynasty, Bruceae Fructus has been recorded in the materia medica, most of the materia medica in previous dynasties took Bruceae Fructus as its proper name, and Laoyadan, Kushenzi and Yadanzi as the aliases. The main origin of Bruceae Fructus is Brucea javanica, its medicinal part is the fruit, which is harvested from August to October every year, the fruit can be harvested when it is ripe. Bruceae Fructus was first distributed in Fujian, Guangdong and Guangxi, and gradually expanded to the south of China with the change of time. The traditional processing method of Bruceae Fructus is mainly to remove the shell and kernel, and remove the oil by frosting. The 2020 edition of Chinese Pharmacopoeia stipulates that its processing method is to remove the shell and impurities. Based on the research results, it is suggested that the dried mature fruit of B. javanica should be selected for the development of famous classical formulas containing this herb, and the raw products can be used if the original formula does not specify the processing requirements.
Résumé
Umbilical cord mesenchymal stem cells (UC-MSCs) have been widely used in regenerative medicine, but there is limited research on the stability of UC-MSCs formulation during production. This study aims to assess the stability of the cell stock solution and intermediate product throughout the production process, as well as the final product following reconstitution, in order to offer guidance for the manufacturing process and serve as a reference for formulation reconstitution methods. Three batches of cell formulation were produced and stored under low temperature (2-8 ℃) and room temperature (20-26 ℃) during cell stock solution and intermediate product stages. The storage time intervals for cell stock solution were 0, 2, 4, and 6 h, while for intermediate products, the intervals were 0, 1, 2, and 3 h. The evaluation items included visual inspection, viable cell concentration, cell viability, cell surface markers, lymphocyte proliferation inhibition rate, and sterility. Additionally, dilution and culture stability studies were performed after reconstitution of the cell product. The reconstitution diluents included 0.9% sodium chloride injection, 0.9% sodium chloride injection + 1% human serum albumin, and 0.9% sodium chloride injection + 2% human serum albumin, with dilution ratios of 10-fold and 40-fold. The storage time intervals after dilution were 0, 1, 2, 3, and 4 h. The reconstitution culture media included DMEM medium, DMEM + 2% platelet lysate, 0.9% sodium chloride injection, and 0.9% sodium chloride injection + 1% human serum albumin, and the culture duration was 24 h. The evaluation items were viable cell concentration and cell viability. The results showed that the cell stock solution remained stable for up to 6 h under both low temperature (2-8 ℃) and room temperature (20-26 ℃) conditions, while the intermediate product remained stable for up to 3 h under the same conditions. After formulation reconstitution, using sodium chloride injection diluted with 1% or 2% human serum albumin maintained a viability of over 80% within 4 h. It was observed that different dilution factors had an impact on cell viability. After formulation reconstitution, cultivation in medium with 2% platelet lysate resulted in a cell viability of over 80% after 24 h. In conclusion, the stability of cell stock solution within 6 h and intermediate product within 3 h meets the requirements. The addition of 1% or 2% human serum albumin in the reconstitution diluent can better protect the post-reconstitution cell viability.
Résumé
Abstract Indices are used to help on decision-making. This study aims to develop and test an index, which can determine the loss (e.g., herbivorous insects) and solution (e.g., natural enemies) sources. They will be classified according to their importance regarding the ability to damage or to reduce the source of damage to the system when the final production is unknown. Acacia auriculiformis (Fabales: Fabaceae), a non-native pioneer species in Brazil with fast growth and rusticity, is used in restoration programs, and it is adequate to evaluate a new index. The formula was: Percentage of the Importance Indice-Production Unknown (% I.I.-PU) = [(ks1 x c1 x ds1)/ (ks1 x c1 x ds1) + (ks2 x c2 x ds2) + (ksn x cn x dsn)] x 100. The loss sources Aethalion reticulatum L., 1767 (Hemiptera: Aethalionidae), Aleyrodidae (Hemiptera), Stereoma anchoralis Lacordaire, 1848 (Coleoptera: Chrysomelidae), and Tettigoniidae, and solution sources Uspachus sp. (Araneae: Salticidae), Salticidae (Araneae), and Pseudomyrmex termitarius (Smith, 1877) (Hymenoptera: Formicidae) showed the highest % I.I.-PU on leaves of A. auriculiformis saplings. The number of Diabrotica speciosa Germar, 1824 (Coleoptera: Chrysomelidae) was reduced per number of Salticidae; that of A. reticulatum that of Uspachus sp.; and that of Cephalocoema sp. (Orthoptera: Proscopiidae) that of P. termitarius on A. auriculiformis saplings. However, the number of Aleyrodidae was increased per number of Cephalotes sp. (Hymenoptera: Formicidae) and that of A. reticulatum that of Brachymyrmex sp. (Hymenoptera: Formicidae) on A. auriculiformis saplings. The A. reticulatum damage was reduced per number of Uspachus sp., but the Aleyrodidae damage was increased per number of Cephalotes sp., totaling 23.81% of increase by insect damages on A. auriculiformis saplings. Here I show and test the % I.I.-PU. It is an new index that can detect the loss or solution sources on a system when production is unknown. It can be applied in some knowledge areas.
Resumo Índices são usados para ajudar na tomada de decisões. Este trabalho teve como objetivo desenvolver e testar um índice capaz de determinar fontes de perda (ex.: insetos herbívoros) e de solução (ex.: inimigos naturais). Eles serão classificados de acordo com sua importância quanto a habilidade de danificar ou reduzir danos no sistema, quando a produção final é desconhecida. Acacia auriculiformis (Fabales: Fabaceae), uma espécie pioneira não nativa do Brasil com rápido crescimento e rusticidade, usada em programas de restauração, é adequada para avaliar um novo índice. A fórmula foi: Porcentagem de Índice de Importância-Produção Desconhecida (% I.I.-PD) = [(ks1 x c1 x ds1)/ (ks1 x c1 x ds1) + (ks2 x c2 x ds2) + (ksn x cn x dsn)] x 100. As fontes de perda Aethalion reticulatum L., 1767 (Hemiptera: Aethalionidae), Aleyrodidae (Hemiptera), Stereoma anchoralis Lacordaire, 1848 (Coleoptera: Chrysomelidae) e Tettigoniidae, e as fontes de solução Uspachus sp. (Araneae: Salticidae), Salticidae (Araneae) e Pseudomyrmex termitarius (Smith, 1877) (Hymenoptera: Formicidae) apresentaram maiores % I.I.-PD nas folhas das mudas de A. auriculiformis. O número de Diabrotica speciosa Germar, 1824 (Coleoptera: Chrysomelidae) foi reduzido pelo número de Salticidae; o de A. reticulatum pelo de Uspachus sp.; e o de Cephalocoema sp. (Orthoptera: Proscopiidae) pelo de P. termitarius em mudas de A. auriculiformis. Entretanto, o número de Aleyrodidae foi aumentado pelo número de Cephalotes sp. (Hymenoptera: Formicidae) e o de A. reticulatum pelo de Brachymyrmex sp. (Hymenoptera: Formicidae) em mudas de A. auriculiformis. O dano de A. reticulatum foi reduzido pelo número de Uspachus sp., mas o dano de Aleyrodidae foi aumentado pelo número de Cephalotes sp., totalizando 23,81% de aumento de danos em mudas de A. auriculiformis. Aqui eu apresento e testo o % I.I.-PD. Ele é um novo índice capaz de detectar fontes de perda e de solução no sistema quando não se conhece a produção final. Ele pode ser aplicado em algumas áreas do conhecimento.

Abstract The use of alternative nutritional sources is an important topic for animal production such as poultry. This study examined the effect of replacing soybean meal with sunflower leaf meal in the diet of laying shaver brown pullets. A total of 30 laying birds were assigned to three treatments of 0% (as control group), 10% and 15% MSFLM inclusion. Four eggs per replicate were randomly taken for three consecutive days at two weeks interval for five times, and 18 weeks individuals were selected after 40 days of experimental time. External parameters of the eggs (egg weight, egg length, egg breadth and egg shape index, shell thickness), and body parameters (Final body weight, weight gain), feed intake and hen day production were measured. For egg length, egg breadth and shell thickness showed significant difference (p 0.05) in from the control birds. Final body weight, weight gain, feed intake and hen day production showed comparable results with values from eggs of birds on control diet. The study revealed the ability of birds to easily utilize the nutrients in the protein sources. MSFLM utilization up to 15% in pullets diet revealed no detrimental effect on the performance of the laying birds and the external qualities of eggs produced.
Resumo O uso de fontes nutricionais alternativas é um tópico importante para a produção animal, como a avicultura. Este estudo examinou o efeito da substituição do farelo de soja por farelo de folha de girassol na dieta de frangas marrons barbeadoras poedeiras. Um total de 30 aves poedeiras foram designadas a três tratamentos de 0% (como grupo controle), 10% e 15% de inclusão MSFLM. Quatro ovos por repetição foram retirados aleatoriamente por três dias consecutivos em intervalos de duas semanas por cinco vezes, e indivíduos de 18 semanas foram selecionados após 40 dias do tempo experimental. Parâmetros externos dos ovos (peso do ovo, comprimento do ovo, largura do ovo e índice de forma do ovo, espessura da casca) e parâmetros corporais (peso corporal final, ganho de peso), consumo de ração e produção diária da galinha foram medidos. Para comprimento do ovo, largura do ovo e espessura da casca apresentaram diferença significativa (p 0,05) nas aves controle. Peso corporal final, ganho de peso, consumo de ração e produção de dia de galinha mostraram resultados comparáveis com valores de ovos de aves em dieta controle. O estudo revelou a capacidade das aves de utilizar facilmente os nutrientes das fontes de proteína. A utilização de MSFLM até 15% na dieta das frangas não revelou nenhum efeito prejudicial no desempenho das aves poedeiras e nas qualidades externas dos ovos produzidos.
