Steggerda, Morris (January 1931) Effect of ovarian injury on date of first egg in fowls. Poultry Science, 10 (2). pp. 98-103.
Abstract
Previous papers by the author have shown that both ovarian and bodily injury caused certain fowls to lay more eggs. It was true also that other hens in the same experiment had their egg production retarded, hence a greater variability among the operated animals (Steggerda ’28 and ’30). In the present experiment the ovary of six-weeks old pullets was injured to note the effect upon the length of time until the first egg was laid. The results indicate a similar stimulation due to the operation since the operated pullets layed on the average sooner than did the control birds.
