Резюме: The influence of the replacement of wheat with 10% of bread waste in compound feed for laying hens on the main indicators of their egg productivity during their second egg-laying year was studied. The laying hens from the experimental group (with bread waste) laid an average intensity of 41.72% and laid 57 eggs per bird on average per egg-laying season. The same indicators in the control birds are 35.71% egg-laying intensity and 38 eggs on average from a laying hen. Experimental laying hens laid larger eggs, both in the periods of peak laying (average 43.11 ± 0.35 against 40.98 ± 0.29 g in the control) and after the peak of egg laying 44.02 ± 0.33 against 42.20 ± 0.24 g at the end of laying, the differences being statistically significant. The authors suggest that the better results in the experimental group are due to the better taste and nutritional qualities of bread waste and higher feed consumption.
