ct-11319	Steel, Richard G. 	A pilot study: Comparison of pregnancy rates from vitrified Jersey embryos utilizing direct transfer methods with pregnancy rates of Jersey and Holstein embryos frozen in ethylene glycol or glycerol by slow-cooling methods	2010	6	.pdf	application/pdf	3393	197	52	Some notable examples are porcine embryos,1 oocytes,2 in-vitro produced embryos3 and Bos indicus embryos.4 Several reports in the literature have described lower pregnancy rates of frozen Jersey embryos when compared to pregnancy rates of frozen embryos from other dairy breeds.5-7 There has been some speculation about the reasons for this occurrence, especially with the discovery that Jersey embryos may have a relatively higher lipid content than embryos from other breeds.7,8 Some investigators have observed that embryos with higher lipid concentrations experience depressed frozen embryo pregnancy rates.1,7,9,10 Although Jersey embryos may possess unique characteristics in their cryotolerance, modification of current vitrification processes utilizing DT methods, combined with further field trials with larger numbers of animals, may help improve overall pregnancy rates with frozen Jersey embryos.	cache/ct-11319.pdf	txt/ct-11319.txt
