Material type: materialTypeLabelBookPublisher: 1997Subject(s): Department of TheriogenologyDDC classification: 0546,T Dissertation note: The present study was intended to study the effect of prostaglandin (PGF2 alpha) and dexarnethasone on reproduction and production of Nili-Ravi buffaloes after parturition. For this purpose eighteen pregnant Nili-Ravi buffaloes were selected on the basis of their breeding history, with good health status, their lactation phases were 3rd, 4th, 6th, 8th, 9th and 10th respectively. These animals were divided into three equal groups viz group A, B and C, each comprising 6 animals. These animals were kept under uniform managemental and feedings conditions. Each buffalo in groups A and B were injected with 20mg dexamethasone and 526ig cloprostenol sodium (PGF2 alpha) intramuscularly on day 10 and 15 respectively before their expected term, while the buffaloes, in group C served as a control. From the present study it was concluded that parturition can be induced at day 10 and 15 prior to their expected term successfully did not affect the production and reproductive efficiency of Nili-Ravi buffaloes. The use of PGF2 alpha and dexamethasone before parturition in buffaloes did not affect the milk yield of each buffaloes as compared with control group, and also the calve birth weight compared with control group. The only complication we found was the retention of foetal membrane, in all the treated buffaloes. No retention of foetal membrane was found in the control group. So the calving interval could be reduced by reducing the duration of pregnancy. It was also concluded that by induction the lactation period could be increased.
