| Popis: | This study was conducted to investigated the effects of feed restriction at early age and re-alimentation (compensatory growth phenomenon) on growth and fattening buffalo calves performance. Twenty four buffalo calves with an average 123±1.05 Kg live body weight (LBW) and aged six months old were used in a feeding trial lasted for (150 – days) as restricted feeding period followed by (90- days) as re-alimentation period using randomized complete block design. Animals were divided into four similar groups (six calves per group) according to their LBW. During the feed restriction period, all animals’ groups were fed the roughage portion (50% corn silage, 40% ammoniated – treated rice straw and 10% berseem hay) at the ad libitum level with supplementation of concentrate feed mixture (CFM) at the levels of 1.5% (T1) as control, 1% (T2), 0.5 (T3) and 0.00% (T4) as tested rations, based on their (LBW). Following, the restriction period, all calves were fed on 2.5% CFM of their LBW plus 1% ammoniated treated rice straw (TRS) over re-alimentation period. In the restricted feed period, results indicated that most of nutrient digestibilities were significantly (P |
