The use of propolis as a source of natural additives to improve the productive performance and immune system of chickens local.1- effect on laying hen performance

Abstract: The study aimed to evaluate the effect of feeding administration of propolis on productive performance, digestibility, egg qualities, semen quality, carcass traits, some blood constituents and economic efficiency. A total of 132 Dokki 4 laying hens, aged 32 weeks, hens was divided into four groups of (30 hens+ 3 cocks). Chicks were randomly divided into control and 3 treatment groups (basal diet containing 100, 200 and 300 mg propolis/kg). The results indicated that:-
1- Final body weight, body weight gain, egg production, egg weight and egg mass for the layers fed diet supplemented with propolis were increased significantly than those fed control diet. Feed intake was not influenced by treatments, whereas feed conversion ratios were significantly improved.
2-Digestibility coefficient values significantly improved for hens fed diet supplemented with propolis compared to those fed control diet.
3- Also, treatment diet supplemented with propolis had significant increased effect on egg shape index (ESI), yolk percentages and shell thickness. However, no effect on albumen and egg shell was found.
4- Moreover, supplementation layer diets with propolis at different levels significantly improved semen quality, fertility and hatchability percentages compared to control.
5-Pre-slaughter weight, dressing, total giblets weight percentage, liver and spleen were significantly (P<0.05) higher for the treatments received propolis than those fed on control.
6- Total microflora count and pH significantly decreased (P<0.05) with increasing propolis.
7-Feeding at different levels propolis lead to significant (P<0.05) decreased of total plasma and yolk total lipids and cholesterol. While, plasma protein, globulin, IgG, IgM, and total plasma antioxidants capacity values were significantly (P<0.05) increased compared to the control group.
8- The immunity responsiveness represented in leukocytes counts and mainly on lymphocytes increased significantly with propolis treatments.
9- Better feed and economic efficiencies were observed with hens fed supplemented propolis.
In conclusion: Supplemented diet with propolis significantly improved productive, reproductive , physiological and immunological status of Dokki 4 chickens and could have better economical efficiency. Keywords: laying hens, propolis, blood components, egg production, digestibility, feed efficiency, immunity, semen quality.
