Abstract

Abstract: 20 castrated Tibetan sheep which were randomly divided into four treatments (group Ⅰ, group Ⅱ, group Ⅲ and groupⅣ)were adopted to investigate the effect of different concentrate levels(150，300，450 g/d) and silage on production performance． The results indicated that average daily gain(ADG)of four groups were （41.00±5.48），（63.00±8.37），（68.00±9.75），（69.00±9.2） g respectively．ADG of group Ⅳ was higher than that of group Ⅰ，significantly(P<0.01), ADG of group Ⅱ and group Ⅲ were higher than that of group Ⅰ，significantly(P<0.05), there was no significant difference among group Ⅱ, group Ⅲ and groupⅣ. The highest feed efficiency showed at 300 g/d concentrate leve1(group Ⅲ), and group Ⅱ (the silage) showed to be more economical than group Ⅲ.

Key words: Tibetan sheep; concentrate level; silage; average daily gain; feed efficiency
