ABSTRACT
Objective@#To investigate the clinical characteristics, diagnostic approach, and treatment of infantile lactose intolerance, and to evaluate the diagnostic value of fecal pH.@*Methods@#The feces and clinical data of all infants(less than 1 year old) diagnosed with simple diarrhea but without signs of infection were collected, who were treated at 4 Grade Ⅲ-Class-A hospitals within the period of June 2012 to June 2015 in Beijing were collected.Lactose intolerance was diagnosed based on urine galactose level, lactose tolerance test, and fecal pH.The clinical characteristics, therapeutic effects and detection methods of lactose tolerance group and intolerance group were analyzed.Then the diagnostic value of fecal pH was evaluated.@*Results@#A total of 217 infants were enrolled in the study, consisting of 113 boys and 104 girls.Their age ranged from 3 to 330 days, 174 infants (80.2%) were less than 6 months old.Among them, 156 infants were diagnosed with lactose intolerance (71.9%), their median age 90.0 days (3-330 days), while the median age of the lactose tolerant group was 51.5 days (3-300 days). The incidence of lactose intolerance in infants less than 6 months old was 70.6%, and 76.7% in those older than 6 months.Clinical characteristics showed that more infants in the lactose intolerant group were breastfed compared with the lactose tolerant group [73/156 cases(46.8%) vs.16/61 cases(26.2%), χ2=7.666, P<0.05], the occurrence of loose foamy feces was higher in the lactose intolerant group [67/156 cases(42.9%) vs.15/61 cases (24.6%), χ2=6.287, P<0.05], the median duration of diarrhea in the lactose intolerant group was 30 days (1-210 days), and that in the lactose tolerant group was 30 days (1-300 days). The incidence of diarrhea more frequent than 10 times per day in the lactose intolerant group was 9.0% (14/156 cases), while that in the lactose tolerant group was 6.6% (4/61 cases). The rate of infection in the lactose intolerant group was similar to that in the lactose tolerant group [32/165 cases((20.5%) vs.17/61 cases(27.9%)]. The median time of recovery by feeding lactose-free formula milk was 2 days (1-60 days), recovery by feeding lactase lasted a median of 4 days (2-25 days), while recovery by using pro-biotics and dioctahedral smectite lasted a median of 2 days (1-5 days). The characteristics of fecal pH showed that mean pH value of fecal and the incidence of fecal pH<5.5 had no statistical significance between the lactose intolerant and tolerant group, between infants ≤6 months and infants>6 months, between the breastfeeding group and formula-feeding group, or between those with infection and those without infection (all P>0.05).@*Conclusions@#Infants with lactose intolerance often manifest foamy feces and tend to be breastfed.Lactose-free treatment efficacy was better than that with lactase.Clinical symptoms when combined with urine galactose level and lactose tolerance test can help diagnosis.However, the decrease of fecal pH proves to be unhelpful in aiding diagnosis.
ABSTRACT
Vinte e dois cordeiros machos não castrados, Dorper x Santa Inês, com aproximadamente 90 dias de idade e peso vivo médio inicial de 27,0±4,4kg, foram alimentados com uma dieta com elevada proporção de concentrado com 20% de pelete proteico-mineral (Grano Entero(r)), 5% de feno de capim coast-cross e 75% de milho, na forma de milho grão inteiro (MGI), milho grão moído (MGM) ou milho grão úmido (MGU), para avaliação de desempenho no confinamento por um período de 14 dias de adaptação às dietas e às instalações e de 65 dias de confinamento. Em seguida, os animais foram abatidos com peso vivo médio final (PVF) de 47,97±5,13kg e o conteúdo gástrico foi avaliado para quantificação de protozoários, e foi realizada avaliação papilar. O delineamento experimental foi o de blocos casualizados. Não houve diferença entre os tratamentos (P>0,05) quanto ao ganho de peso médio diário, eficiência alimentar, ingestão diária de matéria seca, características da carcaça e da carne. Os animais tratados com MGI tiveram maior conteúdo gástrico, menor pH ruminal, maior AP (% da superfície de absorção) e maior área papilar em comparação com os outros tratamentos. Os animais tratados com MGI tiveram melhores resultados para o peso final, mas para os demais parametros estudados não foi observada diferença.
Twenty-two males not neutered, Dorper x St. Agnes, with approximately 90 days of age and average live weight of 27.0±4.4kg were fed with a diet wich contained high concentrate with 20% protein pellet-mineral (Grano Entero (r)), 5% grass hay coast-cross and 75% corn in the form of whole kernel corn (MGI), ground corn grain (MGM) or high moisture corn (MGU) for performance evaluation in confinement for a period of 14 days of adaptation to the diets and facilities and 65 days of confinement. Then the animals were slaughtered at average final weight (PVF) of 47.97±5.13kg and gastric content was evaluated for quantification of protozoa, and a papillary review was conducted. The experimental design was in randomized blocks. There was no difference between treatments (P>0.05) for average daily weight gain, feed efficiency, daily dry matter intake, carcass characteristics and meat. MGI-treated animals had higher gastric contents, the lower ruminal pH greater AP (% of surface absorption) and the larger papillary area was compared with other treatments. Animals treated with MGI had better results for the final weight gain, but for the other parameters studied, no difference was observed.
ABSTRACT
Objective. To evaluate the impact of citrus pulp on the palatability and digestibility of horse diets and the physicochemical characteristics of the feces. Materials and methods. The diets were composed of 60% of the energy from the forage and 40% from the concentrate, with increasing levels of citrus pulp. Two different tests were performed. The first test assessed the palatability of concentrates. Using a randomized experimental design, 15 horses were observed for 10 days. The variables recorded were first action, first choice and intake ratio (IR). Five horses were arranged in 5x5 Latin Square design for the test assessing digestibility and fecal physicochemical characteristics. The apparent digestibility of the nutrients and the color, consistency, pH and buffering capacity (BC) of the feces were evaluated. Results. The addition of increasing levels of citrus pulp had an effect (p≤0.001) on first action. A difference was also observed in first choice, and the addition of 0, 7 or 14% of citrus pulp was preferred. A difference between treatments (p≤0.001) was also observed for IR, and the control concentrate was consumed the most. The amount of citrus pulp included had no effect (p>0.05) on the digestibility of nutrients, fecal consistency and color, and there was no effect (p>0.05) on fecal pH and BC. Conclusions. Horses can identify the presence of citrus pulp in concentrates but prefer concentrates without added citrus pulp. Citrus pulp does not negatively affect the digestibility of concentrates or the physicochemical characteristics of the feces; thus, citrus pulp is a viable alternative ingredient in the formulation of horse diets.
Objetivo. Evaluar la inclusión de pulpa de cítricos en la dieta de los caballos a través de la evaluación de la de palatabilidad, digestibilidad y características fisicoquímicas de las heces. Materiales y métodos. El valor energético de las dietas fue aportado en el 60% por la energía del forraje y en el 40% a partir del concentrado con niveles crecientes de pulpa de cítricos. En la primera prueba se evaluó la palatabilidad de los concentrados. Se utilizó un diseño experimental aleatório. Se observaron 15 caballos durante 10 días. Las variables registradas fueron la primera acción, la primera opción y la relación de la ingesta (IR). Cinco caballos fueron dispuestos en un diseño cuadrado latino 5x5 para la evaluación de la digestibilidad y las características fisicoquímicas fecales. La digestibilidad de los nutrientes y el color, la consistencia, el pH, y se evaluó la capacidad de tamponamiento (CT) de las heces. Resultados. El nível de inclusión de pulpa de cítricos tuvo un efecto (p<0.001) en la primera acción. Una diferencia también se observó en primera elección. Una diferencia (p<0.001) entre los tratamientos también se observó para IR. El nível de inclusión de pulpa de cítricos no efectó (p>0.05) la digestibilidad, consistencia fecal y el color de las heces, pH fecal y CT de las heces. Conclusiones. Los caballos pueden identificar la presencia de pulpa de cítricos en los concentrados, pero prefieren concentrados sin pulpa de cítricos. La pulpa de cítricos no afecta la digestibilidad de los nutrimentos en el concentrado, ni las características fisicoquímicas de las heces; la pulpa de cítricos es un ingrediente alternativo viable en la formulación de dietas para caballos.

The aim of this study was to investigate whether the ingestion of soy yogurt fermented with Enterococcus faecium CRL 183 would modify the intestinal count of enterococci, fecal pH and ammonia content in rats fed on a diet containing red meat. The rats were placed in 4 groups: for 60 days, group I was given a standard casein-based rodent feed and groups II-IV, the beef-based feed. From day 30, groups III-IV also received the following products: III) soy yogurt; IV) suspension of E. faecium CRL 183. At the start and on days 30 and 60, feces were collected for the determination of pH, ammonia content, count of enterococci and identification of their species. On day 60, rats were sacrificed and their colons also removed for count of enterococci and identification of their species. Rats that ingested soy yogurt showed no significant change (P<0.05) in fecal counts of Enterococcus spp., but, this rat group showed a higher count of E. faecium than rats that ingested suspension of E. faecium CRL 183. The ingestion of soy yogurt and E. faecium culture caused a significant rise (P < 0.05) in fecal pH and ammonia content. Our results suggest that consumption of soy yogurt fermented with E. faecium CRL 183 and L. helveticus subsp. jugurti could change the species of Enterococcus spp. present in the feces and colon of rats fed on a beef-based diet. However, the fermented soy product and the pure culture of E. faecium CRL 183 also induced undesirable effects such as the increase of fecal pH and ammonia content in the feces of rats fed on a beef-based diet.
