| Abstract | ||
| The current investigation was designed to determine the effect of treatment with anti-parasitic (Ivermectin) on mastitis and postpartum reproductive performance of Baladi cows.Twenty-four Baladi cows were used in this study, the cows were divided into two groups. The G1 (n= 12 cows) were injected two months prepartum with two consecutive doses (15- days in- between) of IVOMEC®Plus solution subcutaneously at the rate of 1ml/50kg live body weight (prescribed by the manufacturer), whilst G2 (n= 12 cows) was used as a control group. The present results revealed that the occurrence of mastitis in treated cows group was significantly (P <0.05) lower (16.7%) than control cows’ group (41.7%). The conception rate in treated cows group was significantly (P <0.05) higher (66.7%) compared with (33.3%) in control group. The time from calving to conception in treated cows was significantly (P <0.05)lower (86.5± 11.4 days) compared to 123.3±13.2 days in the control group (P <0.05). The occurrence of anestrous was significantly (P <0.05) lower (8.3%) in treated cows than in the control group (25%). The results of this study showed that Ivermectin injection to pregnant Baladi cows during the last two months of pregnancy (at the rate of 1m/50kg live body weight) was useful in reducing the incidence of mastitis, as well as, in enhancing the reproductive performance of the cows | ||
