Effect of Adding Fruit Powder (Brassica oleracea) to the Diet of Ross 308 Broiler Breeder Males on some Testicular Tissue Traits

The aim of this study was to investigate the effect of adding different levels of kohlrabi powder ( Brassica oleracea var. caulorapa. L) to the diet of Ross 308 broiler breeder males on some testicular tissue characteristics. Twenty-five roosters at the age of 45 weeks were divided into five treatments, with five replicates per treatment and one rooster per replicate. Every rooster experienced the same lighting, temperature, and feeding regime. Kohlrabi powder was added to the roosters’ at 5, 10, 15, 20, and 0 mg100 g −1 feed; coded as T1, T2, T3, T4, and T5 respectively. Next, the impact of these treatments on testicular tissue features and body weight was investigated. In comparison to the control group, the results demonstrated a statistically significant (P<0.05) advantage of all treatments in Antioxidant levels. Increases in body weight, certain testicular tissue properties, volumetric density, and the relative weight of interstitial tissue and testicular seminiferous tubule components (%) as a results of study treatments. This study concluded that certain of the active ingredients in kohlrabi powder can enhance some properties of testicular tissue. It caused roosters to become more prolific as they reached an advanced age.
