Effect of freezing temperature, at which straws were plunged into liquid nitrogen, on the post-thaw motility and acrosomal status of ram spermatozoa

Sperm motion characteristics of FecBBB and FecBB+ Garole x Malpura rams during the non-breeding season under hot semi-arid environment

“…(Mittal and Ghosh, 1979;Galil and Galil, 1982;Ibrahim, 1997). The CASA technique provides precise and validated objective sperm motion characteristics (Holt and Palomo, 1996) and has been extensively applied for ram spermatozoa (Edward et al, 1995;Briggs et al, 1996;Joshi et al, 2001;2003;2005;Bag et al, 2002;2004;Kumar et al, 2007;2010); however, care must be taken in preparation of the sample and choosing settings of the instrument (Davis and Siemers, 1995). Davis and Katz (1992; reported that results of CASA are inaccurate if the sperm count for analysis, is below 20 Â 10 6 sperm/ml or above 50 Â 10 6 sperm/ml.…”

Development of single tubing-type canister for cryo-storage of bull semen and their effect on sperm motility and viability

“…On the other hand, many studies have reported the physical changes of the sperm associated with freezing and thawing process (Bag et al 2002;Maldijan et al 2005;Chaveiro et al 2006;Leahy and Gadella 2011). The physical changes during the process of freezing and thawing are quite dramatic (Saacke 1982).…”

Useful impacts of royal jelly on reproductive sides, fertility rate and sperm traits of animals

“…This evaluation differentiates the necrozoospermia from total lack of motility, which signifies the structural defectiveness in zone of the tail (Chemes & Rawe, 2003). The survival of sperm declines due to the freezing or cooling, and the damage degree is related to numerous factors that restrict the survival of sperm during processing (Bag, Joshi, Naqvi, Rawat, & Mittal, 2002).…”
