| Abstract |
A total of 28 newly weaned Damascus kids were divided according to body weight into four groups of 6 kids (3 males + 3 females) with average initial weight of 12.92% 0.70 kg. Kids of G1 was fed on a basal ration (concentrate feed mixture and rice straw) according to the recommended NRC (1981) allowances, while G2 and G3 received 70% of their requirements from CFM and ad lib. green acacia or alfalfa to cover the remaing requirements. Group 4 was fed ad lib. on mixture containing 83% yellow corn, 15% soybeen meal, 1.4% ground limestone, 0.5% common salt and 0.1 % vitamins and trace minerals. The results revealed that digestibility of all nutrients, except CF, and hence the feeding value were significantly (P<0.05) higher for kids fed diet 4 followed by diet3, 1 and diet2, respectively.
Average daily gain from initial weight to marketing weight (30 Kg) was significantly (P<0.05) higher for kids 0 f G4 fed ad lib. on concentrate and reached marketing weight in almost half the period required by those on the other three diets, with no significant differences among groups 1, 2 & 3. Feed conversion as kg OM/Kg gain was the best with kids fed on diet 4 than the other three groups, which were practically similar. Feed cost/kg live weight gain was lower of G4 than the other three groups.
Since concentrates are not available of Sinai and are transported to Sinai from the Nile valley, while acacia plants grow all year round in Sinai and alfalfa is one of the promising forage crops to be cultivated in new reclaimed lands in Sinai, It could be concluded that, using green acacia and/or alfalfa with concentrates is recommended for fattening goat kids in North Sinai.
Keywords: Goat kids, feeding system, acacia, alfalfa, concentrate feed mixture, growth, digestibility, N utilization.
