The Canadian study (Reprod., Fert., and Develop. 18 347-355) showed that limiting the intake of sows during the last week of lactation and the post-weaning breeding period had a significant effect on the number of embryos of different genders. However, for restricted sows, the survival of embryos at 30 days of pregnancy is less, and the proportion of female embryos is relatively low. The results of this study show that the restriction of feeding for the first week of pregnancy in pregnant sows results in a significant reduction in the number of surviving female embryos and limits the total survival of embryos.
