Resumen
Descripción
A genetic study of the grading-up of the East African zebu to the Indian Sahiwal has been undertaken on records, covering about 25 years, from three livestock Improvement Centres in Kenya. It appears from this study that the indigenous East African zebu cow has only about half the genetic potential of the Indian Sahiwal for milk production, and the scheme of grading-up has resulted in substantial and worthwhile increases in milk production.
