Abstract
The current experiment was conducted in the poultry fields of the Department of Animal Production, College of Agriculture, University of Kirkuk, from 20/10/2022 to 31/1/2023. There, 120 Lohman Brown breed laying hens, aged 78 weeks, were employed. This research examined alterations in ovarian, and bone development by using several mechanisms of molting The birds were split up into five experimental treatments, with four duplicates of each treatment. Significant differences were observed between the treatments in both ovary weight and oviduct weight. The T1 and T3 were significantly higher than the other treatments (33.46 and 35.07) g, respectively. Moreover, the oviduct weight of the T1 was significantly higher than the other treatments (85.18) g. Significant differences were found between the treatments in both the tibia weight and femur weight; T1 had a higher significant difference in tibia weight and femur weight than the other treatments (21.14, and 14.44) g, respectively. The dry Tibia weight and the dry Femur weight didn’t show significant differences among the treatments. The effect of different methods of inducing molting on tibia length, femur length, and tibia diameter. Non-significant differences were found among the treatments in these traits. moreover, The results of this study indicate that giving laying hens broken rice diets for a short while is a good way to induce molting and might even be a good way to replace molting. therefore The chickens' inability to produce eggs was likely brought on by the diet's suppression of appetite, which also resulted in ovarian production regression.
