The study of the ovarian cycle of the cow has shown that the development of a fertile follicle is dependent on two metabolically related factors:<\/p>\n

–\u00a0the blood progesterone concentration\u00a0\u00a0<\/strong><\/p>\n

– the reduction of systemic inflammation present in the post-partum phase, especially in the summer period (“heat stress”)<\/strong><\/p>\n

Let’s analyze in detail how the progesterone trend affects the degree of fertility of the cow in the crucial phases of the bovine ovarian cycle marked by the numbering on the graph:<\/p>\n

1<\/b><\/span>\u00a0The high rate of blood progesterone (3.0 ng \/ ml vs 1.3 ng \/ ml) negatively affects ovulation following the execution of the Double Ovsynch protocol (81.1% vs 60%).<\/p>\n

2<\/b><\/span>\u00a0The high rate of blood progesterone increases the possibility of impregnating the cow at the next AF (51% vs 37%) in Ovsynch protocol (n = 564); cows with reduced blood progesterone, on the other hand, had double ovulation. (Cunha et al., 2008).<\/p>\n

4<\/span>\u00a0The concentration of blood progesterone allows the implantation and survival of the embryo at the uterine level; 60% of cows appear to have a value <7.4 ng \/ mL at day 5 post AF. (Stronge et al 2005)<\/p>\n
