Northeastern Brazil has a great ability to raise goats and sheep in the semiarid region, but there is a difficulty in homogeneous production of food during the year. The use of alternative food in feed that is adapted to the semi-arid climate, such as forage palm and manioc, can minimize the problem. The objective of this study was to analyze the effect of different sources of carbohydrates associated with urea in replacement of soybean meal on the ingestive behavior of sheep and goats. Four goats and four sheep with permanent fistula in the rumen were used, arranged in a 4x4 Latin square design, receiving the experimental diets with different sources of carbohydrates and urea replacing the soybean meal. The diets were composed of four treatments: a) corn and soybean meal, b) corn and urea, c) manioc and urea scrap, and d) forage palm and urea. Data were analyzed by analysis of variance and the means were compared by the Tukey test, at 5% significance. There was no significant difference (P> 0.05) in the ingestive behavior between goats and sheep. However, animals fed the diet containing manioc and urea showed a longer time in leisure (977.50 minutes / day), followed by the animals of the diets with forage palm and urea (845 minutes / day) corn + soybean meal (822.50) and corn + urea (821.25 minutes). The feeding and rumination efficiencies were not influenced by the animal species either by the diets. Thus, it is concluded that the association of energetic foods produced in the region (palm and manioc rasa) associated with urea does not compromise the ingestive behavior of goats and sheep.
Desempenho de frangos de corte alimentados com farelo integral de raiz de mandioca (Manihot esculenta Cranz) no período de um a 21 dias de idade
(2021) Silva, Wedja Edite de Oliveira; Holanda, Marco Aurélio Carneiro de; http://lattes.cnpq.br/9825474552364226; http://lattes.cnpq.br/4423714422199215
Objetivou-se avaliar o desempenho de frangos de corte alimentados com dietas com níveis crescentes de farelo integral de raízes de mandioca (0, 25, 50, 75 e 100%) suplementados com carboidrases exógenas no período de um a21dias de idade. Foram utilizados 450 pintos de corte da linhagem Cobb, machos, com um dia de idade, em um delineamento inteiramente casualizado com cinco tratamentos e cinco repetições com 18 aves por parcela. Os parâmetros avaliados foram consumo de ração (CR, g), ganho de peso (GP, g) e conversão alimentar (CA, g/g) nos períodos de um a sete dias e de oito a 21 dias de idade. Os resultados obtidos foram testados para homogeneidade e homocedasticidade, submetidos à análise de variância e para análise da significância foi utilizado o teste de Fisher a 5% de probabilidade e a regressão, utilizando-se o programa computacional R Project 2.13.1 for Windows. Não foram observadas diferenças entre os tratamentos (p>0,05) durante a fase inicial do experimento para as variáveis analisadas. Concluiu-se que o farelo integral de raízes de mandioca pode ser incluído em 100% nas dietas de frangos de corte, em todas as fases de criação, quando suplementado com complexo enzimático de carboidrases exógenas, sem causar prejuízo ao desempenho zootécnico das aves.
Histomorfometria do epitélio omasal de ovinos alimentados com dietas baseadas em palma forrageira

The objective of this study was to evaluate the effect of diets based on forage palm on histomorphometric and histopathological parameters of omasum epithelium and ovine abomasum submitted to forage palm diets. Thirty-two lambs with no defined racial pattern were used, male, uncastrated, with a mean age of six months and initial body weight of 21 ± 2.06 kg, housed in individual stalls equipped with feeder and drinking fountain. The animals were distributed in a completely randomized design with four treatments and eight replicates. The experimental period was 73 days and the experimental treatments consisted of a base diet (elephant grass hay, maize corn meal, soybean meal, urea and mineral salt) and three other diets in which elephant grass hay was replaced in 68% by genotypes of forage palm (small, IPA-Sertânia or Mexican elephant ear), all formulated to allow weight gain of 200 g day-1. After 73 days of confinement, the animals were weighed and slaughtered following the norms in force in the country. The weights of the stomachs and their respective contents were quantified, as well as tissue samples of the omasum and abomasum were collected for histological analysis. Up to the present moment, it can be stated that the diets based on forage palm provided greater stomach weight, with lower content.
