Abstract

Milk production is an important aspect of the dairy animals. The present study was conducted to estimate the effect of different diseases on per day milk yield in the buffaloes. Data from a sample of 1,214 livestock owners in two divisions of Uttar Pradesh namely Agra and Aligarh were collected. The value of reduction in per day milk yield due to different diseases under two different situations, viz. when strata weights were known and when strata weights were not known was estimated. The estimated value of reduction in milk yield under the situation when strata weights were known was 4.28 kg with variance 0.014 kg2. Mastitis is a disease which has a large impact on milk yield in buffaloes. But under the situation when strata weights were unknown and were estimated by double sampling, post stratification and published sources, the estimated value of average reduction in per day milk yield due to different diseases were 4.33 kg, 4.33 kg and 4.35 kg with variance 0.015 kg2, 0.017 kg2 and 0.012 kg2 respectively. In buffaloes, the best estimated value of average reduction in milk was provided by double sampling estimator.
