Nutrition is a major factor affecting cow reproductive efficiency. Long-term moderate or
chronic dietary restriction results in a gradual reduction in dominant follicle (DF) growth rate …

Regulation of ovarian activity is an integrated process encompassing both extraovarian
signals and intrafollicular factors. Initiation of primordial follicle growth and the early stages …

Oocytes of all mammals contain an endogenous lipid reserve. This feature reflects their
shared ancestral origin, the yolk-rich amniote egg. However, the lipid is species-specific in …

A longitudinal study was conducted to examine the relationship between lameness and
delayed ovarian cyclicity during the first 60 d postpartum and days to first luteal activity …

Efficient pasture-based milk production systems require a compact calving pattern aligned to
the onset of the grazing season, a 365-day calving interval and low culling rates for infertility …

Productivity in farm species is controlled by many factors, including ovulation rate. In cattle,
single ovulations occur most frequently and in sheep (and goats) the number of ova …

Diameter deviation is a distinctive change in growth rates among the follicles of a wave,
heralding the formation of a dominant follicle and subordinate follicles. When the follicles are …

Heifers were assigned either low or high (HE) levels of energy intake and low or high
concentrations of dietary crude protein. The effect of these diets on the plasma …

The current knowledge is reviewed concerning correlations between follicular development
in the cow and the competence of matured oocytes to develop into an embryo following IVF …

As soon as the primordial follicle store has been established, usually during fetal
development in ruminants(Juengel et al., 2002), follicles begin to grow. Once initiated …
