Abstract:
Present study was conducted to investigate the effect of feeding varying levels of rice dried distiller grains (rDDGS) on Estrus behavior and physiological peculiarities during estrus period of barbari goats. Twenty-four Barbary goats of 1-2 year age were randomly allocated into 4 groups on average body weight (14.90±0.02) basis (Control, T1, T2, and T3) having 6 animals in each groups. Estrus behavior was monitored twice a day, using a teaser buck. Control group of animals were fed with basal diet, Whereas, T1, T2 and T3 groups of animals were fed with basal diet supplemented with of 10%, 20% and 30% of rDDGS on dry matter basis, respectively for the period of 90 days. The movements of goats were tracked during 10-min observational period by using a video camera recorder, trajectory data were used for the analysis. There were no significant differences in Length of oestrus cycle (days) but the Duration of estrus (hours) affected significantly (p<0.05) lie within the range in the control and treatment groups. The durations of standing and walking of barbari goats another manual observation method determine length of estrus cycle and its duration did affected significantly (p<0.05) lie within the range with treatment groups. The rectal and vaginal temperature during normal and estrus were recorded as (38.50±0.05 °C) and (39.50±0.01 °C), respectively, which is lie within the range. Present result defined rDDGS up to 30 % concentration on DM basis were not any detrimental effect on reproductive parameter of barbari goats.
