[Substitution of protein feed through lysine-supplemented high-protein wheat during the breeding and laying period of hens. 1. Problems, analytical methods used and results obtained in the chick period].
Different parameters were investigated in a trial carried out for the 8-week chick period with an experimental group receiving a protein feed in which 7% of the feed, relative to that of the control group, was replaced by protein-rich wheat. Values for consumption were higher in the controls than in the experimental chicks because of the lower energy content of the ration. Statistically well-established data were obtained indicating that the amounts of crude protein, lysine and sulfur-containing amino acids consumed per unit of weight gain were lower in the experimental group than in the control group. Total body analyses showed that the bodies of the control birds contained more crude protein (alpha less than 0.05) and less fat (alpha less than 0.001). The rate of mortality during the 8-week chick period was 1.1% in the control group and 0.5% in the experimental group.
