Incubation Conditions and Broiler Performance
نویسنده
چکیده
However, the 21 days that the chick spends in the incubator is significant proportion of its life; for a broiler killed at 40 days, 34 % of its total life span is spent in the egg. Recent research has shown that aspects of incubation and hatchery process control can have profound effects on broiler performance all the way up to slaughter weights. Often, small changes will generate significant improvements.
