Abstract

This study was conducted on 16 male Karadi lambs, with an average initial body live weight of 27.00±0.10 kg and 4 to 5 months old were used in this experiment. Lambs were randomly allocated to 4 treatments (4 lambs for each treatment). Feeding frequency started following an adaptation period to the end of the experiment which lasted for 60 days at one meal daily (M1: control treatment), two meals daily (M2: two treatment), three meals daily (M3: three treatment), and four meals daily (M4: fourth treatment).All lambs were received an equal daily allowance of concentrate diet (3%of the live body weight). Straw was given ad libitum. Results showed that lambs fed 4 meals daily had significantly (P≤0.05) higher live body weight (40.80kg) as compared with fed once, twice and thrice daily at the end of the experimental period. Lambs fed on 2 or 4 meals daily consumed significantly (P≤0.05) more feed daily than those fed on once or thrice meals daily. Also, average daily gain(0.217kg), hot carcass weight (20.05kg) and chilled carcass weight (19.89kg) was significantly (P≤0.05) higher for lambs fed on 4 times a day as compared to lambs fed once, twice and thrice daily. Lambs fed 4 times daily had significantly (P≤0.05) higher the dressing percentage 1 (49.14%) and 2 (53.83%), as compared with lambs fed once (46.41 vs 52.10%), twice (47.69 vs 52.80%) and 3 meals daily (46.50vs 52.05%). Results indicated that lambs fed on 4 meals daily had significantly (P≤0.05)  larger rib-eye muscle area (17.90cm2) as compared with lambs fed once, twice and thrice daily. Lambs fed 4 meals daily had significantly (P≤0.05) thinner fat over longissimusdorsi muscle and deposit lower percentage as internal fats than those fed less feeding frequency. Lambs fed 4 meals daily had significantly (P≤0.05)  higher percentage of lean (57.55%)in their carcasses as compared with the percentage of  lean (55.37%)in lambs fed once daily (control).
