Title: Some Production and Reproduction Traits of South Darfur Indigenous Goats
Author: Yassir Ibrahim AL Amin, Hajer
Abstract: Data were collected over 18 months period on the performance of a flock (65 females, 20 males and 38 kids) of Southern Darfur indigenous goats in Beleal (a village 20 km east of Nayala). The goats were kept under an extensive production system based on the grazing of natural vegetation. Supplementary feeding was offered frequently. Mating was controlled during a breeding period of 6 weeks (from mid July to the end of August). Average age and body weight at first kidding were 16.50±0.50 months and 24.95±2.97 kg, respectively. Gestation length was 145.11±4.70 days, kidding percentage was 0.8 kid/doe/year with a litter size of 1.1 kid/doe, sex ratio was 51.3±48.7 for male: female and type of birth was 91.2% single born and 8.8% twin born. Birth weight averaged 2.34±0.36 kg, body weight at weaning (15th week) and 6 months were 11.80±1.00 kg and 12.59 ± 1.58 kg, respectively. Dam body weight and sex of the kids had no significant effect on birth weight. Growth rates averaged 120.43±17.47, 100.33±41.61, 63.6±17.82, -31.89±16.46, 26.28±11.48 and 20.76±7.97 g /d for the first, second, third, fourth, fifth and sixth month of age, respectively. Sex of the kids had no significant effect on different body weights except for the sixth month body weight in which males were significantly heavier than females. Mortalities among the breeding flock and offspring up to six months of age were 29.3% and 35.1%, respectively.
