Reproduction and Milk Production Performance of Buffaloes in East Godavari District of Andhra Pradesh

An investigation was conducted in the Godavari delta, upland, and agency areas of East Godavari district of Andhra Pradesh to study the reproduction and milk production performance of dairy animals. The results showed that the average age at first calving (44.45±0.34 mon), service period (135.70±1.66 days), calving interval (443.78±1.74 days), and dry period (104.65±1.34 days) of graded Murrah buffaloes was significantly (p ≤ .01) lower in Godavari delta area and the mean peak yield (10.92±0.22 lit), lactation milk yield (2183.72±44.66 lit) and lactation period (339.13±1.86 days) of graded Murrah buffaloes was also significantly (p ≤ .01) higher in Godavari delta. The service period (158.92±1.59 days), calving interval (467.43±1.66 days), and dry period (135.00±2.85 days) of local buffaloes were significantly lower in the upland area. The average peak yield (5.92±0.10 lit), lactation milk yield (1183.78±19.57 lit) and lactation period (332.43±3.68 days) of local buffaloes was significantly (p ≤ .01) higher in the upland area. The mean age at first calving (28.90±0.42 mon) and dry period (68.28±1.03 days) of crossbred cows was significantly (p ≤ .01) lower in the Godavari delta than that in the upland area. The mean age at first calving (43.95±0.80 mon), service period (132.14±2.66 days), calving interval (417.86±2.86 days), and dry period (133.57±2.72 days) of local cows was significantly (p ≤ .01) lower in Godavari delta. The average peak yield (4.48±0.09 lit) and lactation milk yield (895.24±17.56 lit) of local cows was significantly (p ≤ .01) higher in the Godavari delta than in upland and agency areas.
