摘要：

The records of Holstein-Friesian and its fractional crosses with Sahiwal were analyzed and evaluated to study the effect of different blood composition on the birth weight of calves. Results showed that animals with 81-90% Holstein-Friesian blood composition produced the heaviest calves while the lightest calves came from the animals with 50-60% Holstein-Friesian blood composition. Furthermore, the bull calves were generally heavier than the female calves in majority of the blood groups. However, the increase in Holstein-Friesian blood composition did not necessarily result to ail increase in the birth weight of calves.
