EFEITO DA ADIÇÃO DE FIBRA EM DETERGENTE NEUTRO EM DIETAS COM PALMA FORRAGEIRA

Abstract

The objective of this work was to evaluate the effect of the addition of neutral detergent fiber levels on dietary with forage cactus on the intake and digestibility of goats. The experiment was carried out at the Experimental Station Pendência (EMEPA-PB), located in the municipality of Soledade-PB. Qualitative characteristics analyses were performed in the Laboratory of Animal Nutrition at the Department of Animal Science at the Federal University of Paraiba (UFPB), Areia-PB. Were used 5 crossbred goats SRD, distributed in a latin square 5 x 5. Were tested five diets incorporated with different levels of neutral detergent fiber from forages (FDNF) on dry matter. There was quadratic effect of neutral detergent fiber levels from the hay of tifton (FDNF) on dry matter intake (DMI), both in grams per day as in percentage of body weight of the goats. The greatest dry matter intakes were of animals subjected to a diet with 10,90% of feed FDNF. There was quadratic effect FDNF levels on the digestibility of MO, NDF and EE. The highest digestibilities of MO (70,83%) and NDF (62,89%) were of the diet with 33,88% of FDNF. However, the highest digestibility of EE occurred at 22,18% of diet (FDNF) 64,62. The diet with 46,32% of FDNF has provided high levels of NDF in the feed (58,51%). However there was a lower NDF digestibility on this diet. The addition of neutral detergent fiber from fodder, between 10,9% and 33,88% on feed dry matter, in diets with cactus forage, resulted in positive effects on digestibility and nutrient consumption by goats.
