Effects of Egg Yolk Source on the Cryopreservation of Stallion Spermatozoa

摘要: Abstract Three experiments were conducted to determine whether replacement of chicken egg yolk, as a component freezing extenders, with yolk from other avian species would improve the post-thaw motility and percentage intact acrosomes stallion spermatozoa. In first experiment, substitution chukar as a lactose–ethylenediaminetetraacetic acid extender, improved (P ≤ .05) These results not replicated in (IMV Technologies, Maple Grove, MN, USA) more expansive study comparing 2%, 4%, 6%, or 8% combined INRA 96 when “slow freeze” method was used, same substitution at levels ranging 13% 22% for diluents used “fast cryopreservation. third study, yolks regular high omega-3 eggs well turkey, chukar, mallard duck analyzed lipid content fatty profile. The turkey higher (1,300 mg/100 g) that ducks lower (560 cholesterol compared two types (range, 1,046-1,094 g). addition, did test acids (4.51 g/100 than 0.28-0.73 Substitution but duck, resulted total spermatozoa obtained three stallions experiment.
