At artificial insemination, heifers were assigned to one of four treatment groups (i.e. HH, HL, LowH and LL) depending on the level of crude protein intake (H = high; L = low) for first and second trimesters of pregnancy. Gonadotrophin concentrations and ovarian parameters were measured in their female calves at 5 and 23 months of age. Crude protein intake was positively associated with dam plasma urea (P &amp;lt; 0.001). The density of healthy follicles in heifers at the time of death was negatively correlated with dam plasma urea at Day 179 (P = 0.009). Heifers from LowH dams had a smaller-sized prepubertal largest ovarian follicle (P = 0.03) and lower densities of primordial and primary follicles (P = 0.02) and healthy antral follicles (P = 0.009) when they were killed. There was a positive correlation between plasma FSH concentrations at 5 and 23 months of age (P = 0.02), as well as between the sizes of the largest ovarian follicles at 6 and 23 months of age (P = 0.01). In conclusion, the reproductive development of heifers may be affected by prenatal nutrition during early and mid-gestation.<\/jats:p>","DOI":"10.1071\/rd09004","type":"journal-article","created":{"date-parts":[[2009,7,7]],"date-time":"2009-07-07T21:39:07Z","timestamp":1247002747000},"page":"773-784","source":"Crossref","is-referenced-by-count":53,"title":["Dietary manipulation of Bos indicus \u00d7 heifers during gestation affects the reproductive development of their heifer calves"],"prefix":"10.1071","volume":"21","author":[{"given":"T.
