ABSTRACT
The success of dairy industry largely depends on the level of production and reproduction performance of the animals and in dairy cattle, milk yield is considered as the most important trait. Crossbreeding programmes has significantly enhanced milk production in India. Despite having less population than indigenous cattle, crossbred cattle have more contribution in milk production of India. Information on first lactation traits enables the breeder to predict the later lactation performance of the animals due to their high correlation with the future performance traits. Performance of these traits in crossbred cattle is generally affected by various genetic and non genetic factors. Proper evaluation or unbiased prediction of genetic worth depends upon the adjustment of effect of these factors on the performance traits. The literature pertinent to genetic and phenotypic parameters of first lactation performance traits i.e. first lactation milk yield (FLMY), first lactation length (FLL), first lactation peak yield (FPY), first dry period (FDP), age at first calving (AFC), first service period (FSP) and first calving interval (FCI) were reviewed in crossbred cattle. In order to improve performance of dairy animals, it is necessary to develop an understanding of the factors affecting first lactation performance traits.
Key words:Crossbred cattle, Heritability, Non-genetic factors
