Abstract

Lactation curve and persistency of the lactation are the important parameters to study the sustainability of the lactation. The present study is based on daily milk production records for 298 lactations (maximum four lactations per animal) from 130 buffaloes belonging to 15 sires. Statistical Packages for Social Sciences (SPSS) programme was used to prepare the lactation curve. Two most widely applied functions to study the lactation curve in Indian buffaloes i.e. gamma and inverse polynomial functions, were fitted to the daily milk yield records of the animals under study. Persistency was studied by carrying out simple analysis through Microsoft Excel 2000 on the weekly milk yield records of the animals. Gamma function was found to be more effective with higher R2 value for all the four lactations to prepare the lactation curve as compared to inverse polynomial function. The value of persistency was found to be ranging from 97.94% to 98.56% for the fourth lactation to the first lactation, respectively. So it was concluded that gamma function can be effectively used to establish lactation curve and predict milk yield of animals on any day of lactation and Surti buffaloes as fairly persistent in milk production throughout the lactations.
