The purpose of the present research was to evaluate the effect of dietary supplementation with different levels of zinc (0, 50, 75, 100 mg/kg diet) on semen quality of Cobb500 broiler breeder males. The four experimental diets were as follows: T1 = the basal diet (control) without any addition (0 Zn). T2 = 50 mg Zn (pure zinc)/kg diet. T3 = 75 mg Zn (pure zinc)/kg diet T4 = 100 mg Zn (pure zinc)/kg diet. The results showed that, Zinc supplementation had significantly (p<0.05) increased spermatocrit, ejaculate volume, mass motility, individual motility, while dead, abnormal sperm percentage and acrosome deformities were depressed (p<0.05) as affected by zinc supplementation throughout study. As well as, dietary treatments influenced sperm concentration and ejaculate volume during the experimental long. Moreover, results also revealed the superiority (p<0.05) of dietary treatments as compared with control group in respect of total mean of all semen quality. © Asian Network for Scientific Information, 2011.

This study was conducted to determine the effect of supplementing the diet with different levels of zinc (0, 50, 75, 100 mg/kg of diet) on sex hormones concentrations of broiler breeder chickens. A total of 132 (96 females and 36 males) of Cobb 500 broiler breeder chicken, 45 weeks old were used in this study. These birds were randomly distributed equally into four dietary treatments with three replicates each. Each treatment group constituted of 32 females and 12 males. Treatment groups were as following: T1: Birds fed the basal diet without any addition (0 Zn) (control), T2: Birds fed diet supplemented with 50 mg Zn (pure zinc)/kg of diet, T3: Birds fed diet supplemented with 75 mg Zn (pure zinc)/kg of diet and T4: Birds fed diet supplemented with 100 mg Zn (pure zinc)/kg of diet. Concentration of testosterone hormone in bird males was determined at 54, 58 and 66 weeks of age, whereas concentrations of estrogen and progesterone hormones in bird females were determined at 54 and 66 weeks of age. Results of this study indicated that adding zinc to diet (T2, T3 and T4) resulted in significant (p<0.05) increase respecting blood plasma concentrations of estrogen and progesterone hormones during 54 and 66 weeks of age as compared with control group (T1). However, dietary supplementation with zinc (T2, T3 and T4) caused significant (p<0.05) increase concerning blood plasma concentration of testosterone hormone at 54, 58 and 66 weeks of age and as regards the overall means of this hormone in comparison with control group. In conclusion feeding diet containing zinc resulted in significant improvement respecting sex hormones (testosterone, estrogen, progesterone). Therefore, adding ration with zinc can be used as a beneficial tool for improving reproductive performance of broiler breeder chicken. © Asian Network for Scientific Information, 2011. Source

The aim of the present study was to evaluate the effect of zinc as feed additive (0, 50, 75,100 mg/kg diet) on fertility traits and sperm egg penetration of Cobb 500 broiler breeders. A total 132 of (96 females and 36 males) of Cobb 500 broiler breeder chicken, 45 weeks old were used in this study. These birds were randomly distributed equally into four dietary treatments with three replicates each. Each treatment group constituted of 32 females and 12 males. Treatment groups were as following: T1: Birds fed the basal diet without any addition (0 Zn) (control), T2: Birds fed diet supplemented with 50 mg Zn (pure zinc)/kg of diet, T3: Birds fed diet supplemented with 75 mg Zn (pure zinc)/kg of diet and T4: Birds fed diet supplemented with 100 mg Zn (pure zinc)/kg of diet. Hens were artificially inseminated with semen from the same treatments during 51, 54, 57, 60, 63 and 66 weeks of bird ages. Fertility traits involved in this study were percentages of fertility, hatchability of total eggs, hatchability of fertile egg, embryonic mortality. However, sperm egg penetration during 54, 58, 62 and 66 weeks of bird age's. Results revealed that adding zinc to birds diet results in significant (p<0.05) increase regarding fertility, hatchability of total eggs, hatchability of fertile eggs and sperm egg penetration and significant (p<0.05) decrease as regards embryonic mortality. In conclusion supplementing the diet of bird with zinc resulted in significant improvement in fertility traits and sperm egg penetration. Therefore adding zinc to the diet of birds could be used as an efficient tool for improves reproductive performance of chicken. © Asian Network for Scientific Information, 2011. Source

The aim of the present study was to evaluate the effect of zinc (Zn) as feed additive on certain seminal plasma traits of broiler breeders' males. A total of 36 Cobb 500 broiler breeders males, 45 weeks old were used in this study. These birds were randomly distributed equally into four dietary treatments with three replicates each. Each treatment group constituted 9 males. Treatment groups were as following: T1: Birds fed the basal diet without any addition of zinc (0 Zn) (control), T2: Birds fed diet supplemented with 50 mg Zn (pure zinc)/kg of diet, T3: Birds fed diet supplemented with 75 mg Zn (pure zinc)/kg of diet and T4: Birds fed diet supplemented with 100 mg Zn (pure zinc)/kg of diet. Results revealed that adding zinc to the diet of roosters (T2, T3 and T4) resulted in significant (p<0.05) decrease in seminal plasma glucose at 54, 58, 62 and 66 weeks of age and protein during 54, 58 and 66 weeks of age and concerning the total means of these two traits in comparison with T1 group. However, feeding diets containing zinc (T2, T3 and T4) resulted in significant (p<0.05) increase in seminal plasma Alkaline Phosphatase (ALP) activity and significant (p<0.05) decrease in seminal plasma Aspartate Aminotransferase (AST) and Alanine Aminotransferasr (ALT) activity and cholesterol concentration during 58 and 66 weeks of roosters age and with relation to the total means of these traits as compared to T1 group. In conclusion, supplementation of the broiler breeder males with zinc caused significant improvement in seminal plasma traits included in this study. Therefore, dietary zinc supplementation can be used as active tool for enhance reproductive performance of roosters. © Asian Network for Scientific Information, 2011. Source

The aim of the present research was to, evaluate the effect of dietary supplementation with different levels of zinc (0, 50, 75, 100 mg/kg diet) on egg quality traits of Cobb 500 broiler breeder hens. The four experimental diets were as follows: T1 = the basal diet (control) without any addition (0 Zn). T2 = 50 mg Zn (pure zinc)/kg diet. T3 = 75 mg Zn (pure zinc)/kg diet T4 = 100 mg Zn(pure zinc)/kg diet. From the applied results which were selected a long the entire research period, we could be conclude the following: All of the egg quality traits and total mean of egg quality of broiler breeders hens were significantly affected by the different levels of dietary zinc supplementation except in both ESG and shell thickness. On the other hand, supplemental dietary zinc detected the highest (p<0.05) egg weight/week as compared to control group and had a significant effect (p<0.05) in accumulative egg weight. © Asian Network for Scientific Information, 2011.
