“…Motility is crucial for achieving fertilization (Palomo et al, 2016), but in the cat, it decreased significantly due to cryopreservation (Filliers et al;Choi et al, 2010). Our results support that PG was efficient for improving sperm motility parameters in frozen samples for all analyzed cats, similar to previous reports for fresh semen (Villaverde et al, 2009(Villaverde et al, , 2014.…”

CHEUQUEMÁN, C.; SÁNCHEZ, R. & RISOPATRÓN, J.Effect of sperm selection techniques in frozen/thawed cat spermatozoa on sperm motility analyzed by CASA system. Int. J. Morphol., 35(4):1495Morphol., 35(4): -1501Morphol., 35(4): , 2017. SUMMARY:Freeze/thawing process reduces sperm survival and fertilizing ability of cat spermatozoa, with sperm motility being the most sensitive sperm parameter altered, due to cryo-damage. In this context, swim-up and density gradient processing methods can help to recover high motile and normal spermatozoa. Maximizing the use of frozen semen sample is essential, especially in endangered felids or high value cats in which sample size, number of samples or access to semen collection is reduced. To our knowledge, there is no previous report describing an in depth analysis of sperm motility improvement, after sperm selection techniques in frozen cat semen. Accordingly, we evaluated the effect of percoll gradient (PG) and swim up (SU) sperm selection techniques on sperm motility parameters and sperm recovery rate in frozen/thawed spermatozoa of domestic cat. Next, we evaluated the individual effect of the cat over sperm motility after PG sperm selection of frozen/thawed spermatozoa. SU and PG improved significantly all sperm motility parameters of frozen/thawed cat spermatozoa compared to simple washing. However, PG allows better sperm recovery from the original frozen sample and works mostly homogeneously among individual cats. This new information could help to maximize the use of frozen semen in endangered felids or high value domestic cats for its subsequent application on in vitro fertilization and artificial insemination.

“…Selenium (Se) and Zinc (Zn) are trace elements known to be important for normal reproductive function in males (Kendall et al 2000;Villaverde et al 2014). Several studies have shown that these elements are important for spermatogenesis and testicular development (Marin-Guzman et al 2000;Yamaguchi et al 2009;Kumari et al 2011).…”

2018) Influences of dietary selenium, zinc and their combination on semen characteristics and testosterone concentration in mature rams during breeding seasonABSTRACT This study was conducted to determine the effect of dietary supplementation of organic zinc (Availa®Zn100) and selenium (Availa®Se1000) on semen characteristics, testes measures and serum testosterone concentration. Twenty Sanjabi rams (50.01 ± 5.6 kg) were randomly divided into four equal groups, given the basal diet as control (C) or supplemented with 0.3 mg/kg Se (SE) or 40 mg/kg Zn (ZN) or 40 mg/kg Zn plus 0.3 mg/kg Se (ZS) for 120 days experiment (from July to November). The semen samples and blood samples were collected every 3 weeks and scrotal circumference was measured every 15 days. The results indicated that scrotal circumference and testosterone concentrations did not differ due to treatment (P > .05). In contrast, semen characteristics were affected by ZS supplementation. The sperm density and total sperm number increased (P < .05) in ZS group. In addition, the progressive sperm motility was higher in ZS (P < .05) than those of SE and C groups. It is concluded that ZS treatment can improve semen characteristics, which may result in overall improvement in reproductive performance of treated Sanjabi rams during the breeding season.
