Abstract
This study aimed at detecting the effects of COQ10 with and without vitamin E on some semen characteristics of the broiler breeder males. Twenty-five males at 43weeks of age divided into five categories of treatment with five replicates. The first treatment (control group) included drenching with corn oil capsules only. The second and fourth treatments were about drenching with capsules containing the COQ10 enzyme at a concentration of 5 mg / male / day with and without10 mg of vitamin E whereas the third and fifth treatments included drenching with capsules containing the Q10 enzyme at a concentration of 10 mg / male / day with and without 10 mg of vitamin E. This whole scheme of treatments was to study their effects on certain semen and seminal plasma properties. The results showed a significant increase (P<0.05) in the ejaculation volume, both individual and mass motility in addition to sperm concentration, all accrediting the fifth treatment. Furthermore, the results clear a significant decrease in the percentage of dead and abnormal sperms. The COQ10 with and without vitamin E led to improved semen quality marking a reduction in AST and ALT, glucose concentration and total protein with improved antioxidant status referring to a high level of GSH and low MDA. We conclude from this study that COQ10 with and without vitamin E has the ability to improve the semen characteristics of age-old broiler breeder males and can improve the status of antioxidants in semen.
Highlights
The intensive genetic selection of economically important traits had a negative impact on the secondary sexual characteristics pertaining to female chicken flocks due to its negative impact on libido and male mating potential especially in fields that depend on natural mating
Ejaculation volume, mass and individual motility and sperm concentration significantly (P≤0.05) improved in those male broiler breeders which received 10/mg/bird/day COQ10 with and without 10 mg/ bird/day vitamin E drenching. The results of this table indicated that the percentage of dead and abnormal sperms were significantly reduced in roosters that received 10/mg/d COQ10 with and without 10 mg/d vitamin E drenching compared to other groups
The results showed that the treatment with Q10 with and without vitamin E led to reducing AST enzyme activity in all treatments of the study compared with control group
Summary
The intensive genetic selection of economically important traits had a negative impact on the secondary sexual characteristics pertaining to female chicken flocks due to its negative impact on libido and male mating potential especially in fields that depend on natural mating. This led to reduced overall flock [1]. The nature and feeding of male broilers and the high sperm production 2.2×109 sperm/day made them more susceptible to oxidative stress caused by reactive oxygen species (ROS) [4] Their production of mitochondria increases naturally or because the effects of premature aging appear on roosters [5,6]. These factors included hereditary, nutrition and management practices [7] or rotating the roosters from hall to hall [8] as well as the addition of materials like medicinal plants that limit the production of free radicals [9] and some vitamins [10] and other transactions
