ABSTRACT

The present study was carried out utilizing 92 lactation records of Murrah buffaloes maintained at Livestock Production Research (Cattle and Buffaloes) Farm of Indian Veterinary Research Institute, Izatnagar. The average protein percentage during first month was 4.12±0.03 which decreased to its lowest value of 3.65±0.04 during fourth month of lactation and thereafter increased continuously during the rest of lactation and attained 3.96±0.05 per cent in the tenth month. The lactation curve for milk protein percentage during a lactation has been observed to have three phases viz., decreasing phase, trough phase and ascending phase just opposite to lactation curve for milk yield. Among the five fitted lactation curve models viz., quadratic, parabolic exponential, inverse polynomial, gamma type and product of two exponential functions, the gamma type [Yt = at−0.1729 exp (0.0390)] was the best representative model explaining milk protein percentage of Murrah during a lactation.
