| Abstract | ||||
| A total number of 64 New-Zealand white rabbits (32 males + 32 females) aged 6 weeks was randomly divided into 8 groups. Each group was subdivided into 8 replicates (4 males + 4 females) and housed individually in a wire cages located in a controlled environmental temperature house (20 – 25 °C) throughout the experimental period (6-14 wks.). Rabbits were fed ad-libitum on high (17% CP) or low (15% CP) level of crude protein and were injected one, two or three times with Ca-Aminoplex at bi-weekly intervals. Ca-Aminoplex is a solution contains some essential Amino acids, vitamin B complex and calcium. The results revealed the following: - Rabbits fed on high protein level had higher (P≤ 0.01) body weight gain compared to those fed on low protein level during the entire experimental period (from 6-14 weeks old). Rabbits injected one, two or three times with Ca-Aminoplex were superior (P≤ 0.05) in body weight gain during all experimental period compared to those in the control treatment (not injected). Rabbits fed on the high protein level (17 % CP) consumed higher feed (P≤ 0.01) compared to those fed on low protein level (15% CP) all over the experimental period. Injection of growing rabbits two or three times with Ca-Aminoplex enhanced (P≤ 0.05) feed consumption all over the experimental period. Rabbits fed on high protein diet had superior (P≤ 0.05 or P≤ 0.01) cumulative feed conversion ratios compared to those fed on low protein diet all over the experimental period. Rabbits injected one, two or three times with Ca-Aminoplex had better (P≤ 0.05) cumulative feed conversion ratios than those un-injected (control) during all studied ages (from 6-14 wks. old). Feeding growing rabbits on the diet of high protein level (17% CP) increased (P≤ 0.01) the cost of feed/rabbit, rabbit price, absolute and relative net revenue and production index compared to those fed on the diet of low protein level (15% CP). Ca-Aminoplex injection increased (P≤ 0.05) the cost of feed/rabbit, but it improved rabbit price, absolute and relative net revenue and production index of growing rabbits. | ||||
