| Abstract | ||
| This work was carried out to study the effect of green cotton plants by-product and whole corn silage on feed intake, nutrients digestibility, nutritive value, growth performance and economic efficiency of fattening Friesian crossbred calves fed the following experimental rations: Ration1 (T1) 100 % of nutritional requirements from concentrate feed mixture (CFM) + Rice straw (RS) as control. Ration2 (T2) 50 % of (CFM + RS) + 50 % of DM whole Corn silage (CS). Ration3 (T3) 50 % of (CFM + RS) + 50% of DM cotton plants by product silage (CPS). Ration4 (T4) 50 % of (CFM + RS) + 50 % of DM (CS + CPS). The results showed that, the calves fed T2 ration which contain wole corn silage and T4 which contain whole corn silage + cotton plant silage had significantly (P<0.05) improved dry matter intake, nutrient digestibility and nutritive value than ration T3 which contain cotton plant silage. The daily body gain of Friesian crossbred calves fed rations T2 and T4 significantly (P<0.05) increased than rations control and T3. Also, feed conversion and economic efficiency of calves took the same trend of daily body gain. It showed that, feeding rations containing whole corn silage or whole corn silage + cotton plant silage improved nutrients digestibility, nutritive value, body gain, feed conversion and economic efficiency of Friesian crossbred calves. | ||
