EFFECT OF ADDING DRIED GINGER RHIZOMES TO DIETS ON SEMEN QUALITY AND FERTILITY RATE IN AGED LOCAL COCKS UNDER EGYPTIAN HOT SUMMER CONDITION.
The present study aimed to investigate the effect of different levels of ginger powder (GP) in Aged local cocks diets on semen quality and fertility rate under Egyptian summer hot condition. Eighty one 60-week-old Mandarah local cocks were utilized in a completely randomized design and were randomly assigned to 3 treatment groups (3 replicates of 9 cocks each) in an individual cages to receive 0.0, 2.5, or 5.0 g ginger root powder (GP) per kg diet for 12 successive weeks (60 to 72 weeks of age). The obtained results showed that dietary GP improved semen ejaculation volume, sperm motility, sperm cell concentration and live spermatozoa. Both levels of GP significantly (P≤0.01) decrease the percentage of sperm total saturated fatty acid and significantly (P≤0.05) increased the percentage of sperm total unsaturated fatty acid of seminal plasma as compared with the control group. Also, Omega 6: Omega 3 ratio was lower in the cocks fed 5.0 g GP/kg diet compared with those under 0 and 2.5 g GP/kg diet groups. Total antioxidant capacity (TAC) significantly (P≤0.05) increased. However, Malondialdehyde (MDA) level and sperm abnormalities (%) were significantly (P≤0.05) lowered in cocks treated with GP than untreated ones. Cocks fed 2.5 or 5.0 g GP resulted in a significant (P≤0.05) increase in fertility rate and hatchability/total eggs rates being 5.55, 14.28% and 14.05, 22.90 % respectively. While, hatchability/ fertility eggs and total embryonic mortality (%) were not affected. Add GP resulted in a significant improvement in the values of follicle-stimulating hormone (FSH), Luteinizing hormone (LH), and testosterone concentrations. It could be concluded that, supplementation of the cocks diet with 2.5 or 5.0 g ginger root powder (GP) per kg diet can be recommended for improving semen quality of and fertility rate especially with the fertility weakness in aged local cocks.
