“…The absence of a sire effect and the hish overall embryonic survival in this study isln contrast to the observations of Swierstra and Dyck (1976). Based on the observations of Tilton and Cole (1982) Swierstra and Dyck (1976 Madsen and Greve (1990) and considerably less than the average of 33.2% at 105 d of gestation reported by Etienne et al (1983) and the estimate of 40-50% mortality quoted by Pope and First (1985) in their review. However, the relatively low mean death loss during gestation and absence of distinct dietary treatment and breed effects on embryonic and fetal survival, suggest that the death loss problem is due to the relatively high incidence of death losses in a minority of the gilts.…”

Dyck, G. W. 1991. The effect of postmating diet intake on embryonic and fetal survival, and litter size in gilts. Can. J. Anim. Sci. 7l:6'75-681. The effect on reproductive performance of restriction of diet intake to body weight maintenance for l0 d after mating (R), versus a daily gain of 0.4 kg (C) was assessed in 264 Landrace (L) (C, 85,1% et R, 82,5%,P>0,10)etd60jours (C,87,8%aetP.,82,4%,P>0,10),nisurlatailledelaport6e(C,9,9 et R, 9,9 porcelets n6s vivants).
