Males are in charge of fertilizing the eggs of 10 broiler breeders, which could correspond to more than 1,000 fertilized eggs per year. The development of testicles, semen quality, and fertility are affected by age, genetic, management, stressors, nutrition, and other factors. However, an adequate nutritional modulation has demonstrated to improve the fertility of males successfully. Then, some nutritional factors will be presented below:
“In poultry males aged over 45 wk, the testicular weight, testosterone level, semen volume, sperm concentration, viability, forward motility, polyunsaturated fatty acids (PUFAs) in sperm (especially n-3 PUFAs), and antioxidant concentrations decrease, whereas seminal plasma lipid peroxidation increases.”
The reproductive system has a risk of oxidative damage due to the PUFA content when vitamin E concentrations are deficient.
In a study, Lohman Brown Breeder Roosters were fed with 100mg of Vit E/kg, demonstrated to improve the semen volume, sperm concentration, and motility percentage. On the other hand, the local roosters in Taiwan fed with 160 mg/kg of Vit E at 49 wk augmented the fertility percentage due to sperm variability and motility improvements.
In conclusion, the reproductive performance of avian species is highly associated with PUFA content which has been improved or not according to the inclusion of dietary mineral and vitamin ingredients. Also, other nutritional factors such as amino acids, probiotics, and phytochemicals have an effect.
