| Abstract | ||
| The effects of using different levels of rumen undegradable protein upon weights and carcasses characteristics of local goats were studied. 24 local goat meal with average age of 4 – 5 months and mean weight of 16.29 ± 0.66 Kg months were used. The goat were divided into 4 groups, each included 6 goats . Goats fed diets containing four levels of undegradable protein 6 , 8 , 10 and 12 gm / kg with constant energy and rumen degradable nitrogen and fed to the goat at rate 3% of life body weight. Results indicate there were no significant differences between treatments in Hot and chilled carcass weights, Dressing percentage on empty body weigh were found for all the groups No significant differences in rib-eye area and fat thickness also the primary and secondary cuts ratio on chilled carcass weight bases and some dissected fats ratio and weight , Fourth treatment showed increased meet percentage (P<0.05) in Physical dissection for ribs cuts compared with second and third groups but no significant differences between Fourth treatment with first treatment ,no significant differences in fat and bone percentage between all group. | ||
