- Variations of protein profiles and calcium and phospholipase A
We studied bovine semen alterations that could influence fertility (Karabinus, 1991), by analyzing proteins, ions and enzymatic activity in thawed semen that, in turn, may influence the acrosome reaction, which has been associated with in vivo fertility.

The estimates of (co) variances and genetic parameters for BW and ADG including or not the components of maternal and cytoplasmic lineage effects, performed by univariate analyses were evaluated according to six different models using lineage variance in.
- Genetic characterization of Aberdeen Angus cattle using molecular
The assessment of genetic variability is especially important in highly specialized livestock breeds since the use of assisted reproduction techniques, such as artificial insemination and embryo transfer, to maintain these breeds can rapidly reduce the.
