Abstract

ABSTRACT
The experiment was conducted on Taggar goats to evaluate the effect of two
different levels of protein and energy in ration on some reproductive and productive
traits. Forty seven (47) mature Taggar goats were used in this experiment. Animals
were allocated to three feeding regimes in a complete randomize design according to
live body weight. The results indicated that supplemented does secured higher litter size
(1.50 and 1.33) compared with 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 time at weaning for supplemented does compared with
control does. These results indicated that supplementation reduced body weight losses
through lactation period. The kidding interval for the supplemented does was shorter
(247.81±8.38 and 242.60±7.88 days) for does in groups B and C respectively compared
with does in control group (288.94±6.84 days). Similarly, the service period had been
reduced in supplemented does compared with control does, the respective values were
74.32±4.96, 83.46±4.67 and 93.08±4.22 days for groups B, C and A, respectively. The
results of milk analysis indicated that supplemented does produced higher protein,
lactose and total solids content whereby the fat content was higher in control does. The
supplementation that given to does had reduced the aborted number and abortion and
mortality rates compared with 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.
