A.S. Series 75-29
The study to be reported here was conducted to determine if the protein level of layer diets could be lowered from the commonly used 16% level to 12% without reducing the performance of hens. Thirty-six 24-week-old Babcock 300 pullets in groups of six were placed in cages and randomly assigned to each dietary treatment. The formulas for the basal diets are shown in table 1. The first treatment consisted of the 11.8% protein diet with the second treatment containing an additional 0.15% methionine hydroxy analogue. Treatments 3, 4 and 5 were obtained by cumulatively supplementing the diet of the second treatment with 0.2% L-lysine, 0.1% DL-tryptophan and 0.4% DL-isoleucine (table 2). Treatment 6 consisted of the standard 16% protein diet.
