Author: Fadlelmoula, A. A.; El Zubeir, I. E. M; Mahmoud, N. M. A.
Abstract: The present study was conducted to evaluate colostrum composition and performance of Damascus goats raised under climate of Sudan. Thirteen Damascus goats at their first parity were selected from a flock owned by the Mamlakat El-Nahal farm in Jabal Awlia, Khartoum state. The traits recorded for the study were age and body weight of dams at first mating and kidding, birth weight and body weight of kids at 2nd and 3rd months of age. The average age of the does at first mating and kidding were 10 and 16.5 months, respectively. Meanwhile the average body weight of the does at first kidding was 56 kg. The average birth weights (kg) of male and female kids were 3.63± 0.03 and 3.47±0.024, respectively. Colostrum was collected daily and the composition was analyzed. The colostral constituents viz. protein, protein fractions, total solids and ash were significantly (P< 0.05) higher in the first day and then decreased sharply in the second day, whereas fat content was found to be stable. The β- lactoglobulin content of colostrum was significantly (P<0.05) higher on the day of kidding (2.01±0.02 mg/ kg) and decreased sharply on the second day (0.45±0.02 mg/ kg). However, all the constituents were significantly (P<0.05) higher in colostrum as compared to milk. Further the concentration of milk constituents were found to decrease as lactation progressed. Moreover all chemical constituents showed significantly (P<0.05) higher levels in the colostrum compared to milk samples and they reduced with the progress of lactation. The present study concluded that Damascus goats can thrive with suitable milk production efficiency in Sudan. Further research is required with respect to the effect of different parity, nutrition and general heath of milking goat under the harsh climate of Sudan.
