Effect of urea-treated sorghum stalks on performance of dairy Shami goat under environment of Halfa alGadidah, Sudan

摘要

Feeding trial was carried out on-farm to examine the effect of urea-treated sorghum stalk onrnthe performance of dairy shami goat. This experiment contained three treatments whichrninclude: untreated sorghum stalk (SS) served as the control, 2% urea (SSU2) and 5% urearn(SSU5). Nine goats were divided into three groups of three in each. The experimental periodrnlasted for 90 day. The three experimental diets were fed and feed intake, water intake, milkrnyield and body weight were recorded regularly. The chemical compositions showedrnsignificant differences (P < 0.05) among DM, CP, CF and ME. The final body weight, dailyrngain, dry matter intake, milk yield was significantly different (P < 0.05). The results suggestrnthat feeding sorghum stalk treated with urea to the level of 5% did not affect goats adversely.
