Influence of complete feed mixture containing naked oat of the Tatran variety on parameters of utility and quality of eggs of laying hens

Abstract

The aim of this experiment was to define the nutritional response of laying hens (Hy-Line Brown hybrid) receiving feed mixture consisting partly of Tatran naked oat on the utility parameters and egg quality in comparison with control group, which was fed a complete feed mixture based on the maize-wheat-soybean extract meal. Totally 72 hens were divided into two groups of 36 animals per each group. In the experimental group, hens were fed with a feed mixture based on 60 % of naked oat of the Tatran variety, maize and soybean extract meal. In the control group, the laying hens were fed with feed mixture based on maize, wheat, soya extract meal and the sunflower oil. Hens of experimental group had statistically significantly higher average of egg production (276.07 ± 0.05 pieces, 16.96 ± 0.004 kg) per 1 hen against control group (267.97 ± 0.062 pieces, 16.11 ± 0.005 kg) (P<0.001). The average weight of eggs was significantly higher (P<0.001) in the experimental group (61.42 ± 3.160 g) compared to the control group (60.13 ± 3.412 g). The number of non-standard eggs per hen was significantly lower (13.79 ± 0.041) in the experimental group in comparison with the control group (15.89 ± 0.045) (P<0.05). Likewise, significantly higher average number of doubleyolk eggs (2.09 ± 0.018) per hen was recorded in the experimental group. Only the colour of egg yolk was significantly higher (P<0.01) in the control group in comparison with the experimental group. For a whole season we recorded significantly higher daily consumption of feed calculated per 1 egg (125.95 ± 17.828 g) and per 1 kg of the egg mass (2.094 ± 0.311 kg) in the control group (P<0.001) in comparison with the experimental group (121.38 ± 14.664 g) per 1 egg and (1.976 ± 0.257 kg) per 1 kg of the egg mass. The results suggest that the naked oat-based feed mixture for laying hens might improve intensity of the egg production, increase the weight of eggs, reduce the number of non-standard eggs and consequently reduce cost of the egg production.
