“…Low Cu levels in the diets are responsible for reduction in reproductive efficiency; these may be due to modification of enzyme systems affected by Cu deficiency and may impede libido, male fertility and even lead to infertility. Kumar et al (2006) and Arangasamy et al (2018b) also reported that testosterone concentration in blood serum was significantly higher in animals of Zn and Cu treated groups as compared to control group. The present results indicate that there is significant reduction in sperm abnormalities in treatment group as compared to control group.…”

“…Zinc (Zn) plays a pivotal role in male reproduction like testicular steridogenesis, androgen metabolism and interaction with steroid receptors and its requirement for testicular growth is greater than body growth and appetite (Bedwal and Bahuguna 1994). Copper (Cu) deficiency is responsible for reduced libido or male infertility (Arangasamy et al 2018b). Moreover, Azolla is an accumulator of heavy metals, vitamin A, beta-carotene and encompasses all macro and micro elements accountable for animal growth, production and are required in spermatogenesis (Srinivas et al 2012).…”

The present study was conducted to evaluate the effect of azolla supplementation on semen freezability in Barbari bucks. Ten adult Barbari bucks (2â€“4 years old) were selected, and divided into control and treatment group (5 bucks in each group) as per completely randomized design. Bucks of control group were fed with 400 g concentrate pellet/day along with 6â€“7 h grazing while bucks of treatment group were supplemented with 100 g fresh azolla along with 400 g concentrate pellet and 6â€“7 h grazing. Semen ejaculates (8) were collected from each buck of control and treatment groups after 60 days of azolla supplementation. Immediately after collection, semen samples were evaluated for colour, volume, density, mass motility, progressive motility, live sperm count, acrosomal integrity and hypo-osmotic swelling positive spermatozoa. Then semen samples were diluted with trisâ€“citric acid fructose diluents having 6% (v/v) glycerol as cryoprotective agent and 10% (v/v) egg yolk. After equilibration, semen samples were filled in straws and vapour frozen for 10 min 4 cm above the liquid nitrogen and finally stored into liquid nitrogen container. Post thaw motility, live sperm count, abnormalities, acrosomal integrity and hypo-osmotic swelling test were conducted to check the effect of azolla feeding on the freezability. Post thaw motility, live sperm count, acrosomal integrity and hypo-osmotic swelling positive spermatozoa were significantly higher in treatment group. It could be concluded that dietary azolla supplementation to breeding bucks improved the quality and freezability of semen favouring the use in artificial insemination program.

“…Our results corroborated Mahmoud et al’s study ( 73 ), in which Moringa oleifera increased sperm quality parameters including the viability of spermatozoa. The addition of organic zinc and copper (antioxidant properties) in the buck’s diet improved sperm viability, plasma membrane and acrosome integrities, and CASA parameters, which were compromised due to oxidative stress ( 74 ).…”

This study investigated the antioxidant effect of quercetin-treated semen on frozen–thawed spermatozoa quality and in-vivo fertility in crossbred Kamori goats. In total, 32 ejaculates from four fertile bucks were diluted in Tris-based egg yolk extender with varying levels of quercetin (0, 1, 5, 10, and 15 μM). Qualified semen samples were pooled and frozen in French straws. The results revealed that the addition of quercetin in the semen extender increased (p < 0.05) frozen–thawed sperm total motility (TM), progressive motility (PM), rapid velocity (RV), average path velocity (VAP), straight line velocity (VSL), curvilinear velocity (VCL), and amplitude of lateral head (ALH) displacement in contrast to the control group. Quercetin supplementation had no effect on beat cross frequency (BCF), straightness (STR), and linearity (LIN) (p > 0.05). Quercetin showed significantly higher (p < 0.05) plasma membrane and acrosome integrity and viability (p < 0.05) of spermatozoa in contrast to the control group. Quercetin in the semen extender significantly increased (p < 0.05) superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), ascorbate peroxidase (APX), and total antioxidant capacity (TAC) levels while reduced (p < 0.05) the contents of total oxidant status (TOS) and malondialdehyde (MDA), which were in contrast to the control group. Ultrasound results revealed that 24 out of 30 (80%) goats were found pregnant when semen was treated with 5 μM quercetin while the control group showed 18 out of 30 (60%) animals were pregnant. Thus, the study concluded that 5 μM quercetin-treated semen was found to be efficient, showed increased antioxidant status, and reduced oxidant production, leading to improved spermatozoa quality and in-vivo fertility in goats.

“…15 Daily dietary supplementation in nondeficient bucks with 12.5 or 25 mg/kg of Cu proteinate increased sperm concentration, motility, membrane integrity, acrosome integrity, and cryosurvival. [16][17][18][19] This was associated with increased expression and activity of SOD-1, CAT, and GPX4 in sperm and decreased lipid peroxidation. 17,18 Supplementation of bucks with Cu also increased plasma testosterone concentrations, sexual behavior, scrotal circumference, and advanced puberty ~ 30 days.…”

Role of trace minerals in bull reproductive physiology and semen quality

Testicular dysfunction is often associated with an imbalance in antioxidant/oxidant homeostasis, leading to negative effects of oxidative stress on germ cell proliferation, steroidogenesis, and sperm function. Trace minerals (TM) are involved in basic homeostatic and enzymatic processes like free radical detoxification, cellular respiration, carbohydrates, lipids, nucleic acids, synthesis and metabolism of proteins, and stabilization of membranes and DNA. Dietary source of TM is necessary to support these processes. Supplementing cattle with TM is nowadays a common practice to help support growth, reproduction, and immunity. This review provides information on roles of TM in bulls testicular and sperm functions, and effects of TM mineral supplementation on bull reproductive parameters.
