Desempenho e perfil sanguíneo de caprinos submetidos a ração de terminação com diferentes volumosos e forma de processamento.

Abstract

The objective of this study was to evaluate different types of volumetric and physical form of the diet in the productive performance of goats finished in confinement system. For the performance test, thirty-two whole goats, F1 (Boer x Savana) mestizos, averaging about 120 days of age (±14) and 16 kg (±2,16) of live weight, were distributed in four treatments (mashed buffel hay, pelleted buffel hay, hay from the cassava area and hay from the pelleted cassava area). The diets were isoproteic and isoenergetic, being in the ratio bulky: concentrate 30:70, balanced for an average daily gain of 200 grams/day for goats with 20 kg of live weight. They were supplied daily at 8:00 a.m. and 4:00 p.m. The experimental period was 60 days of confinement, preceded by 14 days for adaptation to management and diets. The design was completely randomized in factorial 2x2. The dry matter intake as a function of the day, PV and kg 0.75 were significantly higher (P<0.05) when the grain used was the PAM, where the pelleted form was larger in the three consumption conditions. The PB and ash consumption presented significance (P<0.05) as a function of the bulk type, being the buffel superior to MAP. On the other hand, the consumption of FDNcp differed (P<0.05) in the pelleted form where it was superior to the pleated form. The apparent digestibility of PB, ash and NDFcp presented the same behavior of PB, Ashes and NDFcp consumption. Regarding the performance analyzes, both rations promoted better results in the performance of the animals, and the parameters of weight gain, feed conversion, score and biometry presented no significant difference (P>0.05) in relation to the type of bulky and ways of processing the feed. It is concluded, in this work, that both types of bulky and the processed form of the diet offered have similar potential for a good animal performance.
