Techno-economics of periparturient disorders in dairy buffaloes of rural Gujarat

摘要

A techno-economic surveillance on periparturient disorders (268), as influenced by breed (Surti, Mehsani, Jafarabadi, non-descript), season (summer, monsoon, winter), parity (1-8), nutritional status/body condition score (good, fair, poor), housing pattern (pakka, kuccha, open yard) and hygienic condition (good, fair, poor), was undertaken over one year among randomly selected 612 pregnant rural buffaloes of 5 villages around Anand (Gujarat). An attempt was also made to quantify economic losses due to these disorders by generating data at rural households. The overall incidence of periparturient disorders was retention of foetal membranes 8.66%, post-partum metritis 7.84%, sub-clinical mastitis 6.86%, clinical mastitis 5.56%, post-partum genital prolapse 5.23%, milk fever 4.09%, clinical ketosis 2.29%, dystocia 2.12% and pre-partum prolapse of genitalia 1.14%. These disorders occurred more under adverse feeding, housing and hygienic conditions, during monsoon and in 3nd or 4th parity. The per day treatment cost based on prevailing market values of drugs and veterinary services, varied from Rs. 96 to 317, the highest cost being for post-partum prolapse of genitalia and the lowest for post-partum metritis. The average milk lost per buffalo per day was 1.2, 0.8, 2.86, 5.35, 2.57, 3.57, 2.4 and 1.24 lit, respectively, for above disorders. It amounted to total loss of Rs. 84456 and Rs. 66776, respectively, for treatment cost and milk loss from various periparturient disorders. The losses in terms of reduced productive and reproductive efficiency, culling and calf mortality/rearing were difficult to quantify in rupees. So there is scope to apply the changing pattern towards medicine-production-ecology-extension approach at rural level to increase profitability of farmers and to sustain dairy industry.
