Composição tecidual e centesimal de Ovinos Santa Inês e de Caprinos F1 (Boer X SRD) terminados em caatinga raleada enriquecida com capim bufeel (Cenchrus ciliaris L.) e submetidos a dois tipos de suplementação.

Abstract

The objective of this work was to evaluate the effect of supplementation on tissue composition and chemistry loin Santa Ines sheep and goats F1 (Boer X SRD) finished in thinned caatinga enriched with buffel grass (Cenchrus ciliaris L). Used 24 castrated animals, live weight (LW) 20 kg, two supplementation strategies were evaluated: the first was the use of energy supplement (SE) the basis of ground corn (97%), the second was the use of energy-protein supplement (SPE) consisting of soybean meal (50%) plus ground corn (47%) in a completely randomized design in a factorial 2x2 crossover. The loin was dissected into muscle, bone and fat tissue to determine the composition, and the meat was used in the determination of the chemical composition. The use of protein-energy supplementation improves muscle performance loin. Now independent of the type of supplementation, the F1 Boer goats x SRD had higher amounts of muscle while Santa Ines sheep provide greater amount of fat in the loin. Regarding the components did not interfere proximate the type used for supplementation, however sheep Santa Ines lipid values were higher when compared with goats.
