Impact of Bypass Fat on Growth and Testicular Measurements in Gaddi Goat Bucks

The present study was conducted with the objective to compare the morphometric, antioxidative and immunity parameters of Gaddi goat kids fed rumen protected fat and control group for 120 days. Twenty two Gaddi male goat kids (6-8 months) were selected from the flock and divided into two groups (10 kids each) in a completely randomized design. The kids were taken for grazing for 6-8 hours in the day time and offered concentrate mixture 300g to both of the group and in the evening fortified with bypass fat 15g per goat kid in the treatment group. The overall average daily body weight gain in control and treatment group was 60.2 and 76.3 g per day respectively, and significantly higher gain (P<0.05) in treatment group as compared to control. The overall average scrotal circumference and scrotal volume, of Gaddi bucks in control and treatment group were significantly more (P<0.05) in treatment group as compared to control at the end of the experiment (4^th month). The average length of the right testis in treatment group was significantly (P<0.05) higher on 90 and 120 days of treatment. Similarly the width of the right testis in treatment group was more as compared to control at 120 days of treatment. Results of the present study indicate that feeding of bypass fat can be useful strategy for the improvement of growth performance and morphometric parameters in Gaddi bucks.
