Context Dietary strategies may influence the fatty acid composition of sheep meat and ultimately its nutritional and sensory quality. Aim This study investigated the effects of silage to concentrate ratio and feeding duration on the concentration of

Cattle have recurrent follicular waves every 7-10 days in most physiological situations; an FSH increase is associated with emergence of the wave and LH pulse frequency determines the fate of the dominant follicle. To control oestrus with hormones it

Our current working hypothesis for the intracellular mechanism of action for LH and PGF-2 alpha is shown in Fig. 8. Luteinizing hormone appears to act primarily on the small luteal cell through the cAMP/protein kinase A effector system and thereby st

The effects of postpartum energy intake, restricted suckling, and cow-calf isolation on concentrations of LH, FSH, growth hormone, and insulin-like growth factor-I (IGF-I) and on postpartum anestrous interval were determined by randomly allocating be

This study was designed to examine the antisteroidogenic action of prostaglandin (PG) F2 alpha on ovine luteal cells in vitro. Purified populations of large and small steroidogenic luteal cells were treated with lipoproteins, luteinizing hormone (LH)

The prolonged interval from calving to first ovulation in beef cows is primarily due to the suckling-mediated inhibition of pulsatile LH release. Undernutrition both before and after calving also suppresses LH release, reduces ovarian follicular grow

The interval from calving to first ovulation is a major factor affecting reproductive and productive efficiency in beef cows. While this interval is affected by pre- and post-partum nutrition, the maternal-offspring bond is generally considered to be

The interval from calving to first oestrus (post-partum interval) is an important determinant of reproductive efficiency in suckler cows. While this interval is influenced by a range of factors including cow age, breed, presence of bull, cow-calf int
