Changes in the variability of production characters of hens



Changes in the variability of production characters of hens



Ptitsevodstvo (6): 35-36



48 cage-housed White Leghorn line C hens, aged 6 mth at the beginning of the experiment in June 1973, were observed for 20 mth. All hens were subjected to stress by depriving them of light and food for 4 days, and of water for 2 days in 4, in Nov. 1973, May and Oct. 1974, and Feb. 1975.
