ABSTRACT

This study aimed to evaluate phosphorus (P) concentration in serum and bone, the percentage of ash and the specific bone density of buffaloes on Ilha de Marajó before and after mineral supplementation. For this study, 14 crossbred buffaloes of Murrah and Mediterranean descent aged between 18 and 36 months were used. The average values of P before supplementation in serum and bone, the percentage of bone ash and the specific bone density were 5.68mg/dL±1.18, 16.53%±0.53, 59.95%±1.96 and 1.52g/cm3±0.32, respectively, which demonstrated P deficiency in animals raised on Ilha de Marajó. After supplementation with P for a period of seven months, the values were 6.61mg/dL±0.87, 16.90%±0.56 and 60.30%±0.95 and 1.71g/cm3±0.21, respectively. These results showed a significant increase in P concentration in blood serum, specific bone density and percentage of P in ash (P<0.05), but there was no significant increase in the percentage of ash. The average increase in P in the serum and ash did not reach normal levels in all animals; however, 28.6% of the animals had normal values of P in serum and 50% in the ash, and 64.3% had normal specific bone density values. The nonre-establishment, in some of the animals, of the variables of P serum and bone after supplementation for seven months may have occurred as a result of the low intake of the mineral mixture and by the low concentration of P in the Brachiaria brizantha cv. Marandu used for feeding animals during the experiment.


Objetivou-se avaliar as concentrações de fósforo (P) no soro e no osso, o percentual de cinzas e a densidade óssea específica em búfalas da Ilha de Marajó antes e após suplementação mineral seletiva. Foram utilizadas 14 búfalas mestiças de Murrah com Mediterrânea, com idades entre 18 e 36 meses. Os valores médios de P, antes da suplementação, no soro, no osso, o percentual de cinzas e a densidade óssea específica foram de 5,68mg/dL±1,18, 16,53%±0,53, 59,95%±1,96 e 1,52g/cm3±0,32, respectivamente, o que demonstra deficiência de P nos animais criados na Ilha de Marajó. Após a suplementação com P por um período de sete meses os valores foram 6,61mg/dl±0,87, 16,90%±0,56 e 60,30%±0,95 e 1,71g/cm3±0,21 respectivamente. Esses resultados caracterizam um aumento significativo nas concentrações de P no soro sanguíneo, na densidade óssea específica e no percentual de P nas cinzas (P<0,05), porém não houve um aumento significativo no percentual de cinzas. O aumento médio nos valores de P no soro e nas cinzas não alcançou patamares de normalidade em todas as búfalas, entretanto 28,6% delas tinham valores normais de P no soro e 50% nas cinzas, 64,3% tinham valores normais da densidade óssea específica. O não restabelecimento, em parte dos animais, das variáveis ósseas e sanguíneas após suplementação com P durante sete meses pode ter ocorrido em virtude da baixa ingestão da mistura mineral e da baixa concentração de P em Brachiaria brizantha cv. Marandu utilizada para alimentação dos animais durante o experimento.

ABSTRACT

Abstract Background: The global market has an increasing demand for buffalo by-products due to their unique nutritional characteristics. Many buffalo herds lack suitable breeding control programs, hindering the implementation of selection programs. Objective: To evaluate milk production per lactation (MP), lactation length (LL), and calving interval (CI) of a herd of crossbred Murrah buffaloes to support buffalo clustering according to their potential. Methods: Data from 543 lactations between 2002 and 2014 from 105 crossbred Murrah female buffaloes were used. Data were subjected to principal component analysis (PCA) and cluster analysis. Results: The first components (PCs) were responsible for 92.32% of the total variation, of which 61.45 and 30.87% were explained by the first (PC1) and second (PC2) components, respectively. The cluster analysis allowed three female buffalo groups according to their potentials. Conclusion: Buffalo farmers can make decisions on nutritional, reproductive management and cow culling based on grouping.

ABSTRACT

The objective of this study was to evaluate the efficacy of ovulation synchronization protocols forartificial insemination at fixed time (IATF) during a favorable reproductive season in buffalo females in Baixadamaranhense. The experiment was carried out in July with 100 buffaloes of the Murrah breed. Two protocols forovulation synchronization were applied: "GnRH / hCG" and "GnRH / BE". Ultrasonographic evaluations wereperformed to monitor follicular dynamics and ovulation rate and the IATF to evaluate the conception rate. Allthe females responded to the treatments and there was similar follicular growth from the emergency to thefollicular deviation. There was an effect of the ovulation inducer on the diameter of the dominant and ovulatoryfollicle (P <0.05). The ovulation rate was higher in animals subjected to ovulation induction with hCG. Theaverage design rate was 29%. It was concluded that hCG was more efficient in the induction of synchronizedovulation than BE.(AU)

ABSTRACT

This study aimed at evaluating the effects of a selenium enriched diet on the composition and somatic cell count of buffalo milk, along with verifying selenium residue in milk and in Minas fresh cheese. Data from 2264 Murrah buffalo milk samples belonging to Tapuio Ltda., located in the agreste region of Rio Grande do Norte were collected in the period from 2010 to 2014 for analysis. To verify the amount of selenium residue in buffalo milk and in Minas fresh cheese, 100 Murrah buffaloes were used and divided into 5 distinct treatment lots, according to milk production (0.08 ppm/Se/kg of concentrate). Three hundred mL of milk from each lot were collected from the tanks, as well as 300g of Minas fresh cheese, from August to November 2014, with collection of the treated lots held only in the month of November. Selenium supplementation reduces somatic cell count in buffalo milk. Selenium residue was not detected in buffalo milk or cheese. Studies with higher levels that 4.8 ppm of selenium in the diets of dairy buffaloes are recommended(AU)


Este estudo teve como objetivo avaliar os efeitos de uma dieta adicionada de selênio sobre a composição e contagem de células somáticas do leite de búfala, juntamente com a verificação do teor selênio no leite e no queijo Minas frescal. Os dados de 2264 amostras de leite de búfala Murrah pertencentes a Tapuio Ltda., localizada no agreste do Rio Grande do Norte, foram coletadas no período de 2010 a 2014 para a análise. Para verificar a quantidade de resíduo de selênio no leite de búfala e no queijo Minas frescal, 100 búfalas da raça Murrah foram casualizadas em 05 lotes distintos, de acordo com a produção de leite (0,08 ppm/Se/kg de concentrado). Trezentos mililitros de leite de cada lote foram coletados a partir das ordenhadeiras, bem como 300g de queijo Minas frescal, de agosto a novembro de 2014. A suplementação de selênio influenciou a contagem de células somáticas. O selênio não foi identificado no leite e no queijo de búfalas suplementadas com esse mineral. Estudos com níveis mais elevados que 4,8 ppm/kg/Se na dieta de búfalas em lactação são recomendados(AU)

ABSTRACT

O presente trabalho objetivou avaliar, em vacas e em búfalas submetidas à mastite induzida por inoculação de Staphylococcus aureus, a concentração da citocina pró-inflamatória interleucina-1 (IL-1), a contagem de células somáticas (CCS) e a correlação destas com alguns parâmetros da resposta local e sistêmica à inflamação. Os animais tiveram uma glândula mamária inoculada e o processo inflamatório foi monitorado pela cultura bacteriológica do leite, CCS, quantificação da IL-1 na secreção láctea, avaliação da aparência/consistência da glândula, aparência da secreção láctea (resposta localizada à inflamação) e aferição da temperatura retal (resposta sistêmica à inflamação). Houve elevação nos níveis de IL-1, na CCS e resposta localizada e sistêmica à inflamação, tanto na espécie bovina como na bubalina. A cinética da produção da citocina foi diferente nas duas espécies (P 0,05), sendo que as búfalas apresentaram elevação mais rápida, porém com níveis menos elevados, quando comparadas às vacas. As duas espécies alcançaram contagens máximas semelhantes (P>0,05) de CS/mL de leite, com concentrações diferentes (P 0,05) de IL-1/mL de leite. Os parâmetros utilizados para verificar a resposta localizada à inflamação demonstraram escores médios mais elevados na espécie bovina. Correlação positiva entre a concentração da IL-1 no leite, CCS e parâmetros utilizados para avaliar a severidade da mastite foi verificada somente na espécie bovina. Os resultados evidenciaram que a cinética de produção da IL-1 foi diferente nas espécies bovina e bubalina e demonstraram que as búfalas desenvolveram um processo inflamatório mais brando, com restabelecimento mais rápido dos parâmetros utilizados para avaliar a severidade da mastite.(AU)


This study aimed to analyze in cows and buffaloes, submitted to mastitis induced by inoculation of S. aureus, the concentration of the pro-inflammatory cytokine interleukin-1beta (IL-1), the somatic cell count (SCC), and their correlation with some parameters of local and systemic response to inflammation. The animals had one mammary gland inoculated and the inflammatory process was monitored by milk culture, SCC, IL-1 measurement in the milk, evaluation of the gland appearance/consistency, milk secretion appearance (localized response to inflammation) and rectal temperature measurement (systemic response to inflammation). There was increase in the levels of IL-1, SCC, and both local and systemic inflammatory response, in bovine and bubaline species. The production kinetics of the cytokine was different between the two species (P 0.05). Buffaloes showed a faster increase but achieved lower levels of interleukin-1beta, when compared to cows. Both species reached similar maximum counts (P>0.05) of SC/milk mL, with different concentrations (P 0.05) of IL-1/mL. The parameters used to verify the local response to inflammation showed higher mean scores in bovine specie. Positive correlation between IL-1 concentration in the milk, SCC and parameters used to analyze the severity of mastitis was verified only in the bovine specie. The results evidenced that the kinetics of IL-1 production was different in the bovine and bubaline species, and demonstrated that the buffaloes developed a milder inflammatory process with faster recovery of the parameters used for mastitis severity evaluation.(AU)

ABSTRACT

A produção de leite se destaca como uma das principais aptidões das búfalas e é considerada de grande importância em vários países. O mercado para os derivados do leite de búfala está em franca expansão no Brasil. Esses produtos, principalmente a muçarela e a ricota, são procurados não só por seu sabor característico, mas também por suas qualidades nutricionais. As búfalas são consideradas menos susceptíveis à mastite do que as vacas, embora os microrganismos envolvidos na infecção sejam semelhantes. Este artigo aborda aspectos relacionados ao leite de búfala, destacando se produção, características físico-químicas e microbiológicas.


Milk production stands out as one of the main skills of buffaloes, and is considered to be very important in several countries. The market for buffalo milk products is fast growing in Brazil. These products, specially the Mozzarella and the Ricotta cheese, are acquired not only because of their particular taste, but also for their nutritional qualities. The buffaloes are considered less susceptible to mastitis than cows, even though the microorganisms involved in the infection are similar. This article describes several aspects of buffalo milk, particularly production, physico-chemical and microbiological characteristics.

This article describes several aspects of buffalo milk, particularly production, physico-chemical and microbiological characteristics.(AU)

ABSTRACT

Risk factors for subclinical mastitis were studied in 474 buffaloes cows proceeding from four dairy farms located in the states of Pernambuco, Alagoas, Bahia and Ceará, Brazil. Milk samples (n=1896) of lactating buffaloes cows were examined for somatic cells count (SCC) and microbiologic exam, and a questionnaire composed by objective questions was applied in order to obtain animals and herd management data. Risk factors analysis was performed in two stages: univariate and mutivariate analysis. Two analysis were performed, one considering the animal classification for SCC as the dependent variable (<400,000 - negative; >400,000 - positive) and another, considering the microbiologic exam result (positive and negative). In the multivariate analysis considering SCC as dependent variable, the lack of teat washing was the only variable identified as a risk factor, so that farms without this procedure before the milking presented risk of infection of 2.68 (I.C. 1.49-4.83). In the multivariate analysis considering the microbiologic exam as dependent variable, it was observed that properties that performed the cleaning of the milking equipment manually presented risk of 1.85 (I.CI. 1.32-3.64), which was higher than those properties that performed the cleaning mechanically (p=0.019). Risk factors for the occurrence of subclinical mastitis in dairy buffaloes in Brazilian Northeast farms were related to the characteristics of improper milking management. Risk factors identified in this study must be carefully corrected in order to reduce the frequency of mastitis cases, and therefore, contribute for disease control and prevention in the herds.


Foram estudados os fatores de risco para mastite subclínica em 474 búfalas procedentes de quatro propriedades de exploração leiteira situadas nos Estados de Pernambuco, Alagoas, Bahia e Ceará. Amostras de leite (n=1896) de búfalas em lactação foram examinadas para contagem de células somáticas (CCS) e exame microbiológico, e um questionário constituído de perguntas objetivas foi aplicado para obtenção de dados dos animais e do manejo do rebanho. A análise dos fatores de risco foi efetuada em duas eta-pas: análise univariada e multivariada. Foram realizadas duas análises, uma considerando a classificação dos animais quanto à CCS como variável dependente (<400.000 - negativo; > 400.000 - positivo) e outra considerando o resultado do exame microbiológico (positivo e negativo). Na análise multivariada considerando-se a CCS como variável dependente a única variável identificada como fator de risco foi não lavar os tetos antes da ordenha, onde aquelas propriedades que não lavavam os tetos antes da ordenha apresentaram o risco de infecção de 2,68 (I.C. 1,49-4,83). Na análise multivariada considerando o microbiológico como variável dependente constatou-se que aquelas propriedades que realizavam limpeza manual do equipamento de ordenha apresentavam um risco 1,85 (I.C. 1,32-3,64) maior do que aquelas propriedades que realizavam esta limpeza de forma mecânica (p=0,019). Os fatores de risco para ocorrência de mastite subclínica em báfalas leiteiras em propriedades na região nordeste do Brasil foram relacionados às características de manejo inadequado da ordenha. Os fatores de risco identificados nesse estudo devem ser cuidadosamente corrigidos para reduzir a frequência de casos de mastite e assim contribuir para o controle e prevenção da doença nos rebanhos.

ABSTRACT

Realizaram-se estudos para aferir as prováveis causas da baixa taxa de recuperação de estruturas embrionárias em búfalas superovuladas. No primeiro estudo (Experimento 1), foram utilizados sistemas genitais de búfalas e de bovinas tratadas para a indução de ovulações únicas ou múltiplas, os quais foram submetidos à morfometria, seguidos de lavagem dos ovidutos para a recuperação dos oócitos. Posteriormente, os ovidutos foram encaminhados à histologia. No Experimento 2, foram utilizados ovidutos de búfalas e de bovinas, tratadas para a indução de ovulação única. O lúmen do oviduto foi exposto e, após isso, os ovidutos foram incubados em meio de cultura com ou sem E2, com posterior colocação de microesferas na sua superfície para a aferição do movimento ciliar. No Experimento 3, foram utilizados ovidutos de búfalas e de bovinas tratadas para a indução de ovulação única. Os ovidutos foram incubados em meio de cultura com ou sem E2, com a inserção de oócitos bubalinos ou bovinos em seu lúmen, sendo posteriormente lavados para a recuperação e contagem dos oócitos. No Experimento 4, búfalas e bovinas foram tratadas para a indução de ovulações únicas ou múltiplas. Após a ovulação, os animais foram submetidos à laparotomia para a inserção de oócitos bubalinos ou bovinos no oviduto.(AU)


Studies were performed to assess the probable causes of the low embryonic structures recovery rate in superovulated buffaloes. In the first study (Experiment 1) were used buffaloes and bovines genital systems treated to induce single or multiple ovulations, which were submitted to morphometry followed by oviducts flushing for the oocytes recovery. Subsequently, the oviducts were sent to histology. In Experiment 2, were used buffaloes and bovines oviducts treated for single ovulation. The oviduct lumen was exposed and, thereafter, incubated in culture medium with or without E2, with subsequent placement of microspheres on its surface for the ciliary movement measure. In Experiment 3, were used buffaloes and bovines oviducts treated for a single ovulation. The oviducts were incubated in culture medium with or without E2, with the inclusion of bovine or buffalo oocytes in the lumen, and subsequently flushed for the oocytes recovery and counting. In Experiment 4, buffaloes and bovines were treated to induce single or multiple ovulations. After ovulation, the animals underwent laparotomy for the insertion of bovine or buffalo oocytes in the oviduct. Later (five and six days after buffalo and bovine oocytes insertion, respectively), the genital systems were flushed in vivo for the embryonic structures recovery.(AU)
