Effects of delayed access to feed and different crude protein levels in broiler chicks after hatching 2. Physical development of digestive system.

摘要: This experiment was conducted to investigate effects of delayed access feed/water (immediately, after 12 h, 24 h and 48 h) different dietary crude protein levels (low, normal high) on physical development digestive system in broiler chicks hatching. Delayed feed or CP for 0-14 d significantly affected (P<0.05) the absolute relative lengths weights system. A delay accessing water reduced length (cm) weight (g) except pancreas, but increased their (cm/100g BW) (g/100g BW). However, a pancreas. Increasing size It concluded that delaying hatching system, increasing had beneficial these parameters cover adverse early growth period.
