Résumé partiel
Goats are important animals in Sudan and many goat breeds are widely distributed in both rural and urban areas with high populations. In spite of all these facts, goats have low contribution in meat production and consumption. This could be attributed to the low weight gain and meat quality of most Sudanese breeds. Kalahari Red, a meat breed with high live weight, weight gain and good meat quality, was introduced recently to Sudan for improving goat meat production. Consequently, these experiments were conducted to study the body weight and weight gain of the crosses of Kalahari with two Sudanese goat breeds compared to Nubian goats, and to evaluate some carcass characteristics, meat chemical and sensory properties of these breeds. The official weekly growth records of Goat Research Center, Faculty of Agricultural Sciences, University of Gezira, were used in these experiments to study the weight gain of Kalahari × Tagger, Kalahari × Nubian and Nubian goats for 14 months (ages of 3-16 months old). A total number of 18 animals were used included males and females. Six male goats, two from each group, were slaughtered about 18 months old to study body components, carcass characteristics and wholesale cuts. Meat samples from the different breeds were taken and laboratory analyzed for CP, EE and ash. Meat samples were taken from the round wholesale cut of each animal, cut into small slices, mixed together for each breed and cooked in the oven for the sensory evaluation. Data was statistically analyzed using one-way analysis of variance (ANOVA) in complete randomized design (CRD). Duncan’s Multiple Range Test was used for breeds’ means separation and T-test was used to test the effect of sex. Kalahari × Nubian goat was significantly (P≤0.05) higher in live body weight than both Kalahari × Tagger and Nubian goats.
