| Abstract | ||||
| This study was done to determine the effect of feeding system for growing rabbits to improve the productive and physiological response.. Fourty-five V-line male growing rabbits, average age 5 weeks and weighing average of 742.4±5.4 were used in this study. The experiment was lasted for 6 consecutive weeks. The first group was received free feeding of recommended diet daily and served as a control (C), the 2ndgroup (G1), was received 75% of recommended diet daily; the 3rd group (G2), was received free feeding of recommended diet daily for 2 days and fasting for 1 day (skip-a-day system) (G2). Results showed that live body weight and body weight gain of G1 (75%) was significantly (P≤0.05) higher than Cgroup free feeding while, G2 (skip-a-day system) showing the lowest weight. Body weight gain was higher in G1 in compared with C group and G1 but differences were not significant. Feed conversion ratio (FCR) for all restricted groups G1 and G2 were significantly improved (P≤0.05) compared with control group (C). The data revealed that G2 (skip-a-aday system) had the lower feed cost, highest net revenue, highest economic efficiency (EE%) and relative economic efficiency (REE%), however, G1 had the highest net profit. Feed restriction in Growing male rabbits showed the most beneficial effects on live body weight, body weight gain, economic evaluation and carcass traits. | ||||
