Title: Potential Study of Rabbit Meat Production under Sudan Conditions.
Author: Hind Abdelrahman, Abdel Gadir
Abstract: This work was conducted to investigate the reproductive performance and meat production characteristics of temperate rabbit breeds compared with those of local breeds and their crosses under Sudan conditions. Two breeds, New Zealand White (NZW), Sudan Baladi (SB) and their crosses were used. An experiment was conducted for 56 days, employed unsexed thirty six rabbits 12 from each group, and of 42 days age. Feed and water were offered ad libitum, during the experimental period. There was a significant (P<0.01) difference in litter size between NZW and SB breeds. The SB weaned 78% kids of the number born alive; NZW rabbits weaned 87%, while the crossbred weaned 85% kids. New Zealand White rabbits had a significantly (P<0.001) heavier birth weight than SB rabbits. There was a significant breed difference in weaning weight. It was heaviest in crossbred rabbits and least in SB rabbits. New Zealand White rabbits and crossbred ones attained a weight of 1.8 kg at the end of the experimental period, while SB rabbits attained a weight of 1.4 kg only. FCE was highest in NZW and least in SB rabbits. The dressing percentage of the carcass was highly significantly (P<0.001) different among the three groups; the higher dressing percentage was found in the crossbreds. The difference in muscle: bone ratio was significantly higher in SB breed compared with the other two breeds. SB meat had a lower moisture content and higher fat percentage. The protein percentage of NZW rabbit was greater than that of the other two groups. The colour of NZW meat was lighter red than that of SB though not significantly different. The meat of the Sudan Baladi rabbits was tougher than that of NZW and crossbred rabbits. Crossbreeding between the two types of rabbits is advocated.
