Pregnancy rates and expression of mRNA (relative fold change) of genes associated with pregnancy establishment in B. taurus cows receiving Ca soaps of soybean oil (CSSO) or prilled saturated fat (CON+) after artificial insemination. Values reported are least square means ± standard error. Adapted from Brandão et al. [26] 1.

1 Conceptus and endometrial samples were collected on day 15 of gestation and whole blood was collected on day 20 of gestation, whereas pregnancy rates were diagnosed 28 days after AI.
