Theoretical and technical aspects of the cryopreservation of bovine embryos

, : Theoretical and technical aspects of the cryopreservation of bovine embryos. Zootecnia Sao Paulo 32(UNICO): 11-14

An account is given of methods for the freezing and thawing of cattle embryos. The transfer of 712 indigenous and imported frozen embryos to cows in Argentina in 1993-94 resulted in a pregnancy rate of 61.05 and 55.49% respectively, and for embryos of excellent, good, average and poor quality it was 64.85, 60.46, 44.18 and 30.76% respectively.

Quantifying the fitness cost that parasites impose on wild hosts is a challenging task, because the epidemiological history of field-sampled hosts is often unknown. In this study, we used an internal marker of the parasite pressure on individual h...
