Abstract

A single trait linear mixed random regression test-day model was applied for the first time for analyzing the first lactation monthly test-day milk yield records in Karan Fries cattle. The test-day milk yield data was modeled using a random regression model (RRM) considering different order of...

Abstract

The present study was undertaken to estimate the breeding values of 55 Phule Triveni sires for first lactation 300 day or less milk yield (FL300DMY) by using four different sire evaluation methods/models viz. Least Squares (LS), Simple Regressed Least Squares (SRLS), Best Linear Unbiased...

Abstract

In the present study, first three lactation 305-day milk yield variance components, genetic parameters and breeding value were estimated using test-day milk yield and 305-day actual milk yield data of Sahiwal cattle. The estimates were obtained using three methods viz. random regression model (RRM) ...

AbstractFull Text

Agricultural sector would be benefited by use of sexed semen produced by an inexpensive, convenient and noninvasive approach. Mammalian sex is randomly determined with equal chances for male or female progeny. X- and Y- bearing sperm are phenotypically almost similar and it is not easy to separate...

Abstract

The research data spread over a period of 37 years (1976 to 2012) were utilized to study the production traits, viz. first lactation 300 day milk yield (FL300DMY), first lactation total milk yields (FLTMY), first lactation length (FLL) and first dry period (FDP). The 493 first lactation performance ...
