This study aimed to evaluate the effects of forage neutral detergent fiber (fNDF) levels on the voluntary feed intake, digestibility, ruminal fermentation and feeding behavior of goats fed diets with cactus pear. Five non-lactating ruminally cannulated goats fed ad libitum were randomly assigned to a 5 × 5 Latin square design. Treatments consisted of levels of fNDF at 0, 109, 222, 339 and 463 g/kg of dry matter (DM) in cactus pear-based diets. The intakes of DM and NDF were quadratically affected (p ≦ .045) by fNDF levels. Voluntary water intake (VWI) increased linearly as the fNDF levels increased in the diet. The digestibility coefficients of organic matter, NDF and ether extract and total digestible nutrients concentration were quadratically affected (p ≦ .048) by fNDF levels. The ruminal pH linearly increased (p = .001) with fNDF levels, ranging from 5.44 to 5.81 for diets containing 0 and 463 g fNDF/kg DM, respectively. The fNDF levels promoted a linear increase (p = .006) in chewing time, linearly decreased (p = .007) resting time and quadratically affected (p = .033) rumination time. The inclusion of fNDF in the diets provided favorable conditions for ruminal function, digestibility and feeding behavior in goats fed diets containing cactus pear.
RESUMOA presente revisão tem como objetivo explicitar conceitos e informações sobre a cultura da palma, sua origem, introdução, expansão, cultivo, pragas, doenças e uso na alimentação humana e animal. A palma é uma cactácea exótica de origem Mexicana que foi trazida para o Brasil pelos colonizadores, no decorrer dos anos descobriu seu uso na alimentação animal, além da humana, pode ser considerada na atualidade como um dos cactos mais cultivados em regiões de climas áridos e semiáridos devido a sua elevada adaptabilidade em condições adversas. Apresenta potencial de utilização na alimentação humana, animal, produção de energia e vários outros fins. Com a
