Book Description
The present study was undertaken to compare half breds and 3/4th exotic crosses of holstein brown swiss and jersecy with Zebu in two three and four breed combinations. A total of 730 records of different genetic groups were analysed. Growth reproduction and production traits were analysed. The study revealed that holstein sired crosses showed the highest body weights at different ages and excelled all other genetic groups for all reproduction and production traits. Use of superior sires is called for in crossbreeding programme whatever be the exotic breed under consideration. Halfbreeds proved to be the best for growth production and reproduction characters as compared to 3/4th exotic crosses. Intersemating accompanied by selection at 50 percent level inheritance appears to be an ideal long term breeding policy for crossbred cattle.
