Systemic blood was collected from and surgery performed on sows of 3 strains of miniature swine bred for specific SLA (swine MHC) haplotypes (a, c and d) from Day 2 to Day 6 after mating (first day of mating = Day 0). Ovulation rate was determined by counting corpora lutea and embryos were flushed from the uterus. Progesterone, oestradiol-17\u03b2 and oestrone were quantitated in blood plasma and uterine flushings by RIA. SLAd\/d females had a higher ovulation rate than SLAa\/a or SLAc\/c females (11\u00b750 \u00b1 0\u00b787 vs 9\u00b711 \u00b1 0\u00b768 and 8\u00b717 \u00b1 0\u00b783, respectively; P &amp;lt; 0\u00b701). Oestrone was higher than oestradiol-17\u03b2 in systemic plasma (56\u00b75 \u00b1 6\u00b74 vs 33\u00b70 \u00b1 4\u00b77 pg\/ml, P &amp;lt; 0\u00b701) while oestradiol-17\u03b2 was higher than oestrone in uterine flushings (19\u00b78 \u00b1 1\u00b74 vs 14\u00b79 \u00b1 1\u00b75 pg\/horn, P &amp;lt; 0\u00b710). Systemic progesterone concentration was correlated with day after mating (r = 0\u00b793, P &amp;lt; 0\u00b701). There was no effect of haplotype on any of the hormone concentrations measured. Litter size was analysed from 99 matings amongst SLAa\/a, SLAa\/c, SLAa\/d, SLAd\/c and SLAd\/d sires and dams. Litter size from -\/d and d\/d sows or from d\/d boars were larger (P &amp;lt; 0\u00b705) than for all other matings. Although ovulation rate was higher in SLAd\/d sows, the significant effect of sire SLA genotype on litter size suggests an additional effect of the d haplotype on embryonic survival.<\/jats:p>\n                  <jats:p>Keywords: pig; major histocompatibility complex; litter size<\/jats:p>","DOI":"10.1530\/jrf.0.0820595","type":"journal-article","created":{"date-parts":[[2004,3,20]],"date-time":"2004-03-20T01:55:52Z","timestamp":1079747752000},"page":"595-601","update-policy":"https:\/\/doi.org\/10.1530\/rep\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":25,"title":["Influence of SLA haplotype on ovulation rate and litter size in miniature pigs"],"prefix":"10.1093","volume":"82","author":[{"given":"A.
