Effect of early lighting stimulation on egg production performance on laying hens
In (his study, 578 brown hybrid chicks ( Hisex brown) were used to increase egg production per bird and to bring the birds to early sexual maturation by different lighting programs. Ten-hour lighting program was performed until the 14<sup>th</sup> week At the 15 <sup>th</sup>...

| Summary: | In (his study, 578 brown hybrid chicks ( Hisex brown) were used to increase egg production per bird and to bring the birds to early sexual maturation by different lighting programs. Ten-hour lighting program was performed until the 14<sup>th</sup> week At the 15 <sup>th</sup> ıweek, 228 chicks were transported to the cages and 18 hours light was supplied (E.L). The other 228 birds reared on the floor receiving 10 hours light until 17<sup>th</sup> week and at 18<sup>th</sup> and 19<sup>th</sup> weeks 14 hours light and then at 20<sup>th</sup> week of age they were also transported to the cages and they received 18 hours light together with the other group (L.L). Egg production, egg weight, feed consumption, live weight and Ihe number of deformed egg was determined in both groups. Monthly egg production rates of E.L. and L.L. groups were determined as 83,21 ±1.27 % and 68.054 ±1.37 from the 20 weeks of egg respectively in the E.L group the increase in egg production continued in the later periods, but the increase was not significant there was no significant differences between the groups in respect to live weight, egg weight, mortality and feed consumption. In conclusion , early lighting program in layers, without no detrimental effects due to starling early egg production resulted in a slight increase in egg production during the 12 months laying period. |
