The effects of restraint methods on stress hormones (corticosterone, adrenaline, and noradrenaline), blood biochemistry (glucose and lactate), and bleeding efficiency were examined in broiler chickens. Thirty 30 male Ross broiler birds were randomly allocated to either shackling or cone restraint prior to the neck cut. As measures of well-being, physiological data such as alterations in blood metabolites and hormone levels were assessed. Each bird's blood was calculated by comparing its initial body before and after the neck cut for 90 s. The amount of leftover blood was determined using the haemoglobin content of the Pectoralis major muscle. Compared to their shackled counterparts, the plasma levels of adrenaline, noradrenaline, glucose, and lactate were lower in the coned broiler chickens (p<0.05). Those shackled lost significantly less blood than those restrained in a cone. Coned broilers showed significantly less residual haemoglobin in their breast muscles than shackled broilers. It can be concluded that pre-slaughter cone restraint is preferable to shackle restraint. However, a feasible restraint device has not yet been developed.

This study was carried out at the poultry farm of animal production Dep. College of Agriculture –University of Anbar during the period from 28/10/2021 to 8/12/2021 (42 days), to show the effect of adding Cordyceps sinensis (C.S.) extract and a probiotic in Dressing ratio, the relative weights of internal viscera and Microbial content of broilers. 210 chicks one day unsexed chicks of strain (Ross 308) were used with an average weight of 40 g, randomly distributed into 7 treatments, and each treatment containing 3 replicates (10 chicks/replicate) and treatments were as follows: T1: was a control without any addition to the diet, T2 and T3 adding C.S extract at a level of 300 and 600 mg/kg feed respectively, T4 and T5 adding a probiotic at the level of 3 and 6 gm/kg feed respectively, T6 adding of C.S extract at a level of 300 mg/kg feed + the probiotic at a level of 3 gm/kg feed, T7 adding of C.S extract at a level of 600 mg/kg feed + the probiotic at a level of 3g/kg fodder. 6 g / kg feed.
The results showed a significant superiority (P≤0.05) in the dressing percentage in treatments T2, T4, T5 and T7 compared to treatments T1 and T6, and it did not differ from treatment T3. In abdominal fat, treatment T2 was significantly (P≤0.05) superior to the rest of the treatments. There are no significant differences in the relative weight of internal viscera of the body for Fabricia, pancreas, gills, stomach, spleen, liver and heart. In the total microbial content, treatment T5 was significantly (P≤0.05) superior to all treatments and did not differ significantly with treatments T4 and T7. The results also showed a significant improvement (P≤0.05) for the numbers of lactobacilli bacteria in treatments T4, T5, T6 and T7. Compared with treatments T1, T2 and T3, the number of Escherichia coli decreased significantly (P≤0.05) in treatments T3, T5, T4, T6 and T7 compared with the control treatment T1, and it did not differ significantly with treatment T2.
We conclude from this that the addition of Cordyceps Sinensis extract and the probiotic at the above levels improved the microbial performance of the intestines, abdominal fat, relative weights of internal viscera and the dressing rate of broilers without any negative effect.

This experiment was conducted to investigate the effect of various skip feeding programs on some carcass characteristics of mixed sex broiler chicks. Two Hundred- Forty unsexed 1 day-old commercial strain broiler chicks were included in the experiment. Broilers allocated randomly to four treatment groups with four replicates each and 15 chicks per replicate. The feeding programs were as follows; (T0): Control treatment (The feed is placed in front of the birds on a permanent basis), (T1) Skip every 1 day, (T2) Skip every 2 days, and (T3) Skip every 3 days. Birds were fed ad libitum for two weeks. At age 42 days, one male and female were randomly chosen from each replicate to estimate the carcass characteristics. The results showed that during 14-42 days of age, significant differences (P≥0.05) were obtained for (dressing, breast, back, wings, thigh, drumstick, liver, heart, and gizzard) weight (g) in different skipping programs in males and females. Dressing, breast and thigh weights were significantly increases in group (T0) as compare with other groups. Significant increases were recorded for relative weights of liver, heart and gizzard for males in group (T1), while it was mentioned that characteristics and abdominal fat in females of group (T3) were increased in weights. The effect of treatments on chemical composition of breast, thigh and wings in both sexes were not significant differences except the fat percentage was significant improvement (P≥0.05) in breast percentage for (T2). No significant differences were observed in thigh and wings in both males and females except percentage of fat content in breast in group (T2) which recorded high values.
