Induced moulting in a commercial flock


, : Induced moulting in a commercial flock. Ptakhivnitstvo (28): 52-54

39 735 White Leghorn females at a commercial farm were subjected to induced moulting at 22 mth of age using withdrawal of feed and water, and a modified light regime. The moulting period lasted approx. 40 days, and during the following 7 mth the egg production rate was 59.6-71.7% and survival rate was 96.5%.
