Insufficient feed supply is a major limiting factor for milk production in the tropics. The aim of this study was to assess the effects of feeding level on live-weight and performance of Zebu (Boran) and crossbred (Boran × Holstein, 50–75% Holstein) lactating cows. Twenty-four heifers of each bre...

This paper Reports on both the individual and combined effects of age at first caving (AFC) and live weight at first calving (LWFC) for crossbred heifers (Friesian x Zebu) on first lactation Milk yield. Optimal health and nutrition management was followed. Fifty one heifers were allocated to youn...
