Background: Litter size in mice is an important fitness and economic feature that is controlled by several genes and influenced by non-genetic factors too. High positive selection pressure in each generation for Litter size at birth (LSB), resulted in the development of high and low prolific lines of inbred Swiss albino mice (SAM). Despite uniform management conditions, these lines showed variability in LSB across the generation.

Due to the difference of estrogen levels in different phases of estrous cycle, it is necessary to exclude the influence of endogenous estrogen when studying the cardiovascular effects of estrogen and its analogues. In this study, the ischemia/reperfusion (I/R) injury of isolated heart were investigated in female rats during different phases of estrous cycle with male rats as comparison. The results indicated that the estrogen content in blood of rats during metestrus and diestrus (MD) was lower than those during proestrus and estrous (PE).

Wnt7a-Cre is a commonly used for generating uterine epithelial conditional knockout mice, such as epiERα-/- (Esr1f/-Wnt7aCre/+) and epiPR-/- (Pgrf/-Wnt7aCre/+). We noticed that epiERα-/- females, but not epiPR-/- females, have prolonged plugging latency, which is the duration between continuous cohabitation and detection of the first vaginal plug (a sign of mating). Mating occurs in proestrus and/or estrus stages of the estrous cycle.

This study aimed to develop a non-surgical method to neutralize reproduction in female dogs. Female Beagle puppies, aged 6 days, were treated with pellets designed to release estradiol benzoate (EB; 1.0 mg) and progesterone (P4; 5.

Olive cake was incorporated at a low inclusion rate (3.7%) into the rations of dairy cows through partial substitution of maize, and its effects on milk production, general health, and fertility traits were investigated. Multiparous purebred Holstein dairy cows (n = 148) were divided into two groups: a treated group (n = 86) and a control group (n = 62).
