The reproductive efficiency of the entire sheep flock could be improved if ewe lambs go through puberty early and produce their first lamb at 1 year of age. The onset of puberty is linked to the attainment of critical body mass, and therefore we test

Plasma concentrations of growth hormone (GH) are elevated in sheep during undernutrition. The present study attempted to determine whether this increased secretion mediated nutritional effects on reproduction or wool growth, using sheep immunized aga

The rôle of growth hormone (GH) in normal growth is well established, but its rôle during recovery after live-weight loss in adults is less defined. This study examined the interaction of endogenous GH with energy or protein supplements during re-f

The twinning rate of ewes is poorly related to plasma concentrations of gonadotropins. In this study, we tested an alternative hypothesis for the control of twinning rate, by testing whether nutritional treatment sufficient to affect twinning could a

During earlier studies we observed that ewes housed and sampled intensively to measure pulses of LH in plasma had a higher ovulation rate than similar ewes housed outside. In Expt 1, we pursued this observation by testing whether the increase was due

Molecular genetics provides an increasing capacity to modulate the function of individual genes, but the practical implications of these technologies are still poorly understood. This study examined adult Merino or Merino-cross sheep that had an addi

Ovariectomized ewes were immunized against cortisol, oestrogen or progesterone to determine whether steroids of non-ovarian origin occur in sufficient amounts to influence the reproductive system. Ewes immunized against oestrogen (oestrone + oestradi

This study examined whether the low body-fat reserves in sheep with high estimated breeding values (EBVs) for clean fleece weight (CFW) reported previously are affected by nutritional history, and second whether the effect may be related to differenc

Effects of high growth hormone (GH) activity on body composition and some aspects of meat quality were examined in sheep transgenic for an additional copy of the ovine GH gene, as a tool to explore the biological importance of the GH axis in sheep se
