abstract：:The effects of undernutrition on the timing of puberty and regulation of LH secretion by the inhibitory and stimulatory feedback action of estradiol were examined in female sheep. The first experiment determined that maintenance of low BW (ca., 20 kg, four lambs) between 10 and 45 weeks of age prevented initiation of ...
