“…However, our CASA data analysis provides clear quantitative evidence that older males produce fewer motile sperm and that these sperm have poorer forward movement. The CASA parameters of sperm movement (VCL, VSL) have previously been reported to be positively correlated with sperm mobility and egg fertility in turkeys as well as quail (Farooq, Malecki, Mahmood, & Martin, ; Hirano et al, ; King et al, ). In humans also, age‐related declines in %MOT, %Rapid and %PROG and other sperm kinematics are linked to lower egg fertilization rate (Abramsson, ; Sloter et al, ).…”

“…Kinematic measures of sperm motility are widely considered important for assessing ejaculates and fertility in a wide variety of species (Amann, ; Bakst & Cecil, ; Farrell, Foote, Simkin, Clegg, & Wall, ; Holt, Holt, Moore, Reed, & Curnock, ; Klimowicz, Nizanski, Batkowski, & Savic, ; Long et al, ; Moore & Akhondi, ). The CASA technology has been used to evaluate potential fertility in a variety of poultry species, including the broiler chicken and turkey, as well as quail (Farooq, Malecki, Mahmood, & Martin, , ; King, Holsberger, & Donoghue, ; Long et al, ). Moreover, changes in sperm motility parameters with advancing age have been documented in humans (Johnson, Dunleavya, Gemmell, & Nakagawa, ; Sloter et al, ).…”

For successful breeding programs, it is important to quantify the useful period of a male's reproductive life and it is often done simply by measurement of semen quality. This information is lacking for Japanese quail so we tested whether there is a decline in ejaculate quality and sperm kinematics with age, and whether the decline varies among strains. Nine males (n = 9) from each of 5 strains (A, B, C, D and E) were subjected to 4 semen collections (n = 16 per male) at 8, 16, 26 and 36 weeks of age. Ejaculate volume, sperm concentration and total sperm per ejaculate were measured, and sperm kinematics were analysed using a Sperm Class Analyser (SCA®). There was a significant effect of age for ejaculate volume, total sperm per ejaculate and per cent medium sperm. The effect of the interaction between age and strain was significant for percent progressive motile sperm, percent rapid sperm, velocity curvilinear, velocity straight line, velocity average path, linearity, straightness and beat cross frequency. Ejaculate volume peaked at Week 26 in all strains, while peak values for sperm concentration and total sperm per ejaculate were observed at Week 16 for most strains. There were declines in percent motile sperm, progressive motile sperm and rapid sperm, and in velocity curvilinear velocity, velocity straight line and velocity average path, by Week 16 for most strains. Linearity declined by Week 26 in some strains, and all strains showed a significant decline in beat cross frequency by that age. In conclusion, the ability of CASA to detect age‐related changes in sperm kinematics makes it a valuable tool for identifying the best males and thus improving quail flock fertility. It is essential that breeders understand that age affects both sperm production and sperm kinematics, and that the changes vary with strain.

“…The cloacal gland is androgen‐dependent (Sachs, ), and thus, in males, cloacal gland index, testis weight and testosterone meditation are highly correlated. Foam secretion from the cloacal gland, whose physiological importance is still controversial, may also affect the fertilizing capability of spermatozoa cloacal foam production, cloacal gland index, testicular weight and testosterone concentration are highly linked with each other and may serve as indirect indicators for predicting the fertilizing ability of male quails (Farooq et al, ; Hooda et al, ; Mohan, Moudgal, Sastry, Tyagi, & Singh, ).Yet, α‐tocopherol acetate , potent antioxidant, was found in the fowl semen which prevents the chain oxidative reaction thus maintaining the fertilizing ability of spermatozoa representing its role in male reproductive system (Chelmonska, Jerysz, Lukaszewicz, Kowalczyk, & Malecki, ; Farooq et al, ; Majid et al, ). There was no published report available on the effects of feed containing the supplements such as Pinus ponderosa leaves and α‐tocopherol acetate powder on male reproductive system, serum metabolites and carcass quality of Japanese quails.…”

“…In Japanese quail, no literature is available to report the fertilizing ability of quail semen. However, the cloacal gland located in the dorsal wall of the cloaca is unique to the male Japanese quail and is a dependable display of testicular movement and fertilizing ability in Japanese quails (Farooq, Malecki, Mahmood, & Martin, 2018;Siopes & Wilson, 1975). There is a relationship between the mass of the cloacal gland and testis weight (Farooq et al, 2018).…”

The aim of the current study was to evaluate the effect of dietary supplementation of Pinus ponderosa leaves (pine leaves) and α‐tocopherol acetate (vitamin E) powder on male reproductive system, serum metabolites and carcass characteristics of Japanese quails. A total of 360‐day‐old male quails were purchased from the open market and kept at poultry shed for ninety‐four days. After ten days of adaptation, all quails were randomly assigned into 4 groups, control (IC); supplemented with α‐tocopherol acetate (IE) at the rate of 150 mg/L; Pinus ponderosa leaves (IP) at the rate of 150 mg/L; and 70 mg α‐tocopherol acetate and 70 mg Pinus ponderosa leaves (IEP). Pinus ponderosa leaves and α‐tocopherol acetate supplementation had not significantly (p > .05) effected on final body weight gain, feed intake and feed conversion ratio of quails. The high‐density lipoprotein cholesterol (HDLC) and total cholesterol (TC) were significantly (p > .05) affected by IE and IP groups as compared to IC and IEP groups. Triglyceride (TG), glutathione peroxidase (GPx) and superoxide dismutase (SOD) significantly (p < .05) increased in all treatment groups except for the IC group. Aspartate transaminase (AST) significantly (p > .05) decreased in treatment groups as compared to control group. Overall, the mineral levels significantly (p < .05) increased in treatment groups as compared to control. Cloacal gland index values, the quantity of foam production and testis weight were significantly (p < .05) increased in treatment groups. It was concluded that the supplementation of Pinus ponderosa leaves and α‐tocopherol acetate improved the testis weight, foam production, serum antioxidant enzymes and mineral level especially zinc in Japanese quail considered an indicative characteristic of higher sperm production rate and improved sexual activity. Further, higher gametogenesis rate, sperm production or reproductive behaviour including different hormonal level will be analysed in future study.

The study evaluated the effect of time of the year in which changes in photoperiod occurs on ostrich semen characteristics and male libido. Semen was collected for five days before, on and five days after winter solstice (21 st June 2016), spring equinox (22 nd September 2016), summer solstice (21 st December 2016) and autumn equinox (20 th March 2017) in the southern hemisphere. Semen was collected from 10 South African Black ostrich males (average age ± standard deviation: 4.5 ± 2.27 years) using the dummy female. Semen volume, sperm concentration, total sperm per ejaculate, sperm motility traits, percentage of normal sperm, head and tail abnormalities and percentage of affected sperm in the hypo-osmotic swelling test (HOS) were evaluated. Male libido defined as the willingness of males to mount the dummy female was also recorded. Semen samples collected around summer solstice, spring and autumn equinox were higher in sperm concentration and sperm output compared to winter solstice (P < 0.05). Study periods did not influence semen volume, sperm motility traits, the percentage of normal sperm, head abnormalities and HOS. Tail abnormalities were higher around winter solstice than around spring equinox (P < 0.05). Male libido and the success of semen collection were significantly higher around spring equinox (P < 0.05). Changes in photoperiod in the southern hemisphere do not affect semen production in ostriches. However, high sperm output and male libido around spring equinox 2 and summer solstice dates suggest that these periods may be preferred for semen collection for artificial insemination and storage purposes.
