The study was conducted in Taggar goats to evaluate the effect of two different levels of protein and energy in the rations on some reproductive and productive traits. Sixty two (62) kids of Taggar goats were allocated to sex and birth type in a complete randomized design according to live body weight. The results indicated that supplemented does secured higher litter size 1.50 and 1.33 compared to control group 1.2. Kidding rate was high in supplemented groups 100% compared with control group 93.8%. Body weight was heavier at time of kidding and weaning for supplemented does compared with control does. These results indicated that supplementation reduced body weight losses throughout the lactation period. The kidding interval for the supplemented does was shorter for does in group B (247.81±8.38 days) and group C (242.60±7.88 days) compared to does in control group (288.94±6.84 days). Similarly, the service period had been reduced in supplemented does than those in control group. Results from milk analysis indicated that higher protein, lactose and total solid content in supplemented does whereby fat content was higher in control group. The supplementation had reduced the incidence of abortion and mortality rates compared to the unsupplemented does. In conclusion the investigated environmental factors showed an impact on both reproductive and productive traits of the Taggar goats under rangeland farming system.
