ABSTRACT This study was designed to evaluate the effects of adding kefir on body measurements, giblet weight, and gut morphological patterns of geese through drinking water. A total of 54 birds were divided into three groups, each comprising 18 birds, and each group was further divided into three subgroups containing six birds each. One group served as the control group, while the other two groups were given kefir-treated drinking water at the ratios of 2.5 and 7.5%, respectively. No significant […]

This study was developed to evaluate the effects of adding L-glutamine and L-glutamate in diets with no lactose or with 4.0 or 8.0% lactose inclusion for piglets weaned at 21 days old. One hundred and eight piglets with initial weight of 6.12±0.70 kg were allotted in a complete randomized block design, in a 3 × 2 factorial arrangement, with six treatments, six replicates, and three piglets per experimental unit. The experimental diets were supplied from 21 to 35 days. From […]

Um experimento foi conduzido para verificar o efeito da utilização de níveis crescentes (0, 10, 20, 30 e 40%) de farelo de canola nas rações de frangos de corte, sobre o desempenho e a morfologia da mucosa, durante o período inicial (1 – 21 dias) e os efeitos de sua utilização no período de crescimento. Foram utilizados 1000 pintos machos de um dia de idade, distribuídos em delineamento experimental inteiramente casualizado, com cinco tratamentos, quatro repetições e 50 aves por […]
