Productive qualities of a pheasant depending on illumination level

Analysis of different illumination levels on the productive qualities of a pheasant have showed that experienced pheasants have productivity higher than the control ones for three months by 59.83%, 22.4% and 14.38%, and in the fourth month the difference is 32.24%. Egg production of experimental and control pheasants for the initial and average laying hen differs by 17.66 and 21.72%. For the entire period of oviposition, the case is 4 and 8 heads of females. Egg productivity by tiers shows the superiority of experienced pheasants by 30.56%. Similar results are obtained for the productivity of poultry for the initial and average laying hen with a difference of 41.46 and 40.64%, which indicates minimum illumination of the lower tier and, as a result, a decrease in the reproductive abilities of the control group of birds. The analyzed morphological parameters of eggs do not reveal significant differences between the studied groups on which basis it can be assumed that the assessed factors do not affect the studied indicators. During the egg-laying period in the experimental group of pheasants feed consumption is higher by an average of 9.22% and energy consumption used to maintain the level of illumination is higher. And for the entire productive period the difference between the experimental and control groups is 0.33 kg or 6.1%, which can be explained by the greater productivity of the experimental group. The successful adaptation of the common pheasant to cellular conditions of keeping due to the doubling of illumination factor leads to early stimulation of egg laying, followed by an increase in the egg productivity of the bird, which may exclude its seasonality. Therefore based on our results we can recommend using a lighting mode of 50-60 lux, which will increase the egg production of poultry by 30.56%, reduce the case by 2.4%, and on average by 0.7%. But at the same time feed costs will increase by 6.1%, which is explained by the higher productivity of the experimental group.
