Better management practices and congenial Environment play an important role in ensuring better fertility among crossbred cattle in the state, according to a study by researchers ofKeralaVeterinary and Animal Sciences University (KVASU).
The study is based on data collected from 1,180 crossbred cattle sired by 208 Frieswal bulls, spread over a period of 16 years from 2003 to 2019. The cattle have been maintained at different farms of the university. A team of genetic scientists from the Centre For Advanced Studies in Animal Genetics andBreeding,KVASU-Thrissur, found that there is no co-relation between high milk yielding cows and fertility.
The findings were published in Elsevier Science Direct-Estimation of co-Variance components and genetic parameters of fertility and production traits in crossbred cattle of Kerala withJamuna Valsalanas the lead author.
