COMPORTAMIENTO PRODUCTIVO DE OVINOS DE PELO USANDO UN EXTRACTO COMERCIAL DE TANINO CONDENSADO

Abstract

The objective of this study was to evaluate the viability of using commercial SilvaFeed® condensed tannins (CT) when they are added to sheep’s diets in 4 % DM. The study lasted 60 d, 22 sheep were used, in a completely random design with 11 repetitions per treatment. The following were evaluated: productive behavior (daily weight gain, dietary conversion and dietary efficiency), dorsal fat (EGD), and eye area of the rib (AM). The diets were formulated according to the sheep’s requirements, being iso-proteic and iso-energetic. The data were analyzed with the SAS software PROC GLM. The inclusion of 4 % of CT to the diets showed that the DM consumption was 1200 g d^-1, the daily weight gain, dietary conversion, AM and EGD were not different between treatments (P>0.05). This study indicated that the inclusion of 4 % of CT to the sheep’s diet did not affect the productive variables.
