TL;DR: The analysis of the rates of growth and atresia suggest that the rate of growth is slowest during mid-cycle, and the number of dominant follicles that developed in the ovary ipsilateral to the corpus luteum was greater than in the contralateral ovary.

TL;DR: Nutrition is a major factor affecting cow reproductive efficiency and negative energy balance or reduced dietary intake in the early post-partum period, while not affecting the population of small-to-medium size follicles, adversely affects the size and ovulatory fate of the dominant follicle.

TL;DR: Data provide clear evidence to support the hypothesis that P(4)-induced changes in the uterine environment are responsible for the advancement in conceptus elongation reported previously in cattle and that, interestingly, the embryo does not need to be present during the period of high P( 4) in order to exhibit advanced elongation.

TL;DR: Poor nutritional management of the dairy cow, particularly before and after calving, is a key driver of infertility.

TL;DR: Validation of a number of genes by quantitative real-time PCR indicated that P4 supplementation advances endometrial gene expression by altering the time (FABP, DGAT2, and MSTN) or duration (CRYGS) of expression pattern for genes that contribute to the composition of histotroph.
