Insulin-like growth factor-I (IGF-I) plays a pivotal role in cattle fertility, acting as a monitoring
signal that allows reproductive events to occur when nutritional conditions for successful …

Reproductive efficiency is not optimal in high-producing dairy cows. Although many aspects
of ovarian follicular growth in cows are similar to those observed in heifers, there are …

The objective was to examine the associations of peripartum concentrations of nonesterified
fatty acids (NEFA), β-hydroxybutyrate (BHBA), and calcium with milk production in early …

Reproductively normal crossbred beef heifers were individually offered a diet of barley straw

Simple Summary After calving, the milk production of dairy cows increases rapidly, but the
nutrient intake cannot meet the demand for milk production, forming a negative energy …

Transgenic CBA mice expressing either the tyrosine kinase GTK (gut tyrosine kinase) or the
adaptor protein SHB (Src homology 2 protein of beta-cells) under the control of the rat …

The objective of this study was to determine the effect of an injection of 10% butaphosphan

The efficiency of milk production in pasture-based systems is heavily influenced by calving
pattern, necessitating excellent reproductive performance in a short-breeding season …

The aim of this study was to examine the direct effect of lactation on the ability of the
reproductive tract of postpartum dairy cows to support early embryo development. Twenty …

The objective of this study was to evaluate the mechanism of action through which
