Journal ArticleDOI
Influence of prepartum nutrition on the reproductive performance of beef females and the performance of their progeny.
TL;DR: Two experiments were designed to assess the importance of maternal nutrition in the later stages of gestation on reproductive performance of beef females and on the growth and survival of their calves and there was a tendency for a higher percentage of adequately-fed heifers to show estrus by 40 days postpartum.
Journal ArticleDOI
Nutrition and the postpartum interval of the ewe, sow and cow.
T. G. Dunn,C. C. Kaltenbach +1 more
TL;DR: The effects of nutrition on the length of the postpartum interval (PPI) were reviewed for the ewe, sow and cow, finding that in mature Merino ewes, neither lactation nor undernutrition during lactation affects the duration of the PPI while both factors increase the duration in coarse-wool breeds.
Journal ArticleDOI
Prepartum and Postpartum Levels of Progesterone and Estradiol in Beef Heifers Fed Two Levels of Energy
TL;DR: Twelve first-calf, 2-year-old, Hereford heifers were randomly assigned in equal numbers on two levels of energy and there was no significant effect of nutrition on peripheral levels of progesterone or estradiol either prior to or following parturition.
Journal ArticleDOI
Pituitary and ovarian function in postpartum beef cows. I. Effect of suckling on serum and follicular fluid hormones and follicular gonadotropin receptors.
D L Walters,D L Walters,C. C. Kaltenbach,C. C. Kaltenbach,T. G. Dunn,T. G. Dunn,R. E. Short,R. E. Short +7 more
TL;DR: Removal of the suckling stimulus increases pulsatile LH release and the accumulation of Prl in the follicular fluid, which may be responsible for the increase in follicular LH receptor concentrations that were observed in the W cows.
Journal ArticleDOI
Pituitary and ovarian function in postpartum beef cows. III. Induction of estrus, ovulation and luteal function with intermittent small-dose injections of GnRH.
TL;DR: It is concluded from the indirect evidence obtained from these data that suckling prolongs the postpartum interval of the beef cow by reducing the frequency of pulsatile GnRH release from the hypothalamus.
