Oral administration of royal jelly may improve the preservation of rooster spermatozoa

Abstract

Of the fundamental problem of the poultry production industry is the variation of fertilizing potential of males in the different flocks. The management, environment, nutrition and genetics can be the cause of the difference in rooster quality and fertility. Among these traits, mating behaviour and diet play a critical role in the subfertility of most roosters in the breeder farms. Also, the more sperm abnormality and low viability are seen in the male bird having higher weight and more prevalence of infertility. Damaging of spermatozoa

Royal jelly may improve sperm characteristics during preservation of rooster semen: Gene expression of antioxidant enzymes

“…(2020) demonstrated that the superabundance of fatty acids secreted by SSTs has detrimental effects on sperm storage in the oviduct of chickens, which may cause damage to sperm and decreased fertility. Also, our recent work showed that the feeding of high‐level RJ to the rooster decreased the sperm quality parameters (Rahnama et al., 2020). It seems that the high levels of fatty acids and polyphenolic compounds of royal jelly had a detrimental effect on the semen characteristics during liquid storage and freeze‐thaw processing of rooster semen.…”

“…The RJ has a large number of bioactive molecules with hypoglycaemic and anti‐inflammatory, antioxidant, vasodilation and hypotension, and anti‐hypercholesterolemia properties (Lucas, 1942; Moradi et al., 2013). Several in vitro studies have reported that the supplementation of RJ to the semen diluents of ram (Moradi et al., 2013), buffalo (Abd‐Allah, 2012), goat (Alcay et al., 2017), poultry (Rahnama et al., 2020) and bull (Abd–Allah, 2010) improved the sperm fertility parameters during the chilled and frozen conditions. Also, our previous studies show that the addition of RJ to the oocyte maturation media has a positive effect of in vitro sheep embryo metabolism and development (Eshtiyaghi et al., 2016; Valiollahpoor Amiri et al., 2016).…”

Improving Reproductive Performance and Health of Mammals Using Honeybee Products

“…Proline has been demonstrated to maintain sperm cell membrane integrity under stressful conditions [108] and both cysteine and proline act as robust antioxidant agents to eliminate ROS and stimulate glutathione enzyme synthesis and activity during semen cooling-freezing processes [108]. Moreover, royal jelly vitamins (C and E) and 10-hydroxy-2-decenoic acid provide protective effects to the sperm cell membrane [109,110]. However, high concentrations of royal jelly produced negative impacts on sperm cell quality [103], thus careful consideration of the concentration in media is essential.…”

Honeybee and Plant Products as Natural Antimicrobials in Enhancement of Poultry Health and Production

“…It can be used in poultry production to improve the growth, gut health, and immune response and produce high-quality and safe poultry meat [119]. Previous studies focused on supplementing with royal jelly (10 to 200 mg/kg) in poultry diets have shown a significant increase in body weight (7%), egg production (10%), semen quality, and immune levels, as well as producing organic products [120]. Besides, El-Tarabany [52] conducted an experiment to clarify the influence of royal jelly on behavioural patterns, feather cover, egg quality, and some blood haematological indices in laying hens (58-64 weeks of age).…”
