Evaluation of different induce forced resting events in the blood qualities of commercial laying hens

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 – 31/1/2023), where 120 Lohman Brown breed laying hens at 78 weeks of age were employed. The birds were split up into five experimental treatments, with four replicates of each treatment. The results show that there are highly significant differences between the treatments, as the first treatment significantly differing among the other treatments in the level of ALT and AST enzymes (15.43, and 28.72) respectively. As for the ALP enzyme, the third and fourth treatments were higher significantly then the other treatments (54.91, and 57.35) respectively. As a highly significant difference was found in the level of calcium in the blood, the fourth and fifth treatments outperformed the other of the treatments (4.12, and 4.12) respectively. The level of phosphorus in the blood was not significant. The table shows that there are highly significant differences, as the first treatment was significantly superior to the rest of the treatments in the levels of cholesterol, albumin, and glucose (4.10, 20.15, and 19.66) respectively. As for total proteins, the first and second treatments outperformed the rest of the treatments (55.83, and 53.11) respectively. The using different recourse to induced molting improves the blood characteristics for the layer’s hen and increase the level of calcium in the blood serum, and increase the level of ALP in the blood. We believe that these findings will contribute to enhance the molting of laying hens.
