Introduction:In mated sows, corpus luteum (CL) function is important for the establishment of the pregnancy. The maximum CL size is established at day 8 - 9 of the pregnancy and maintained autonomous until day 12. Then, CL maintenance will depend on hormones such as LH and PGF2α. PGF2α is released from the endometrium at day 14 and triggers CL regression. This regression can be prevent ...

Introduction:The genetic selection for increased litter size has resulted in a disproportionate increase in ovulation rate (OR). A higher OR was linearly related with decreased placental length at day 35 of pregnancy, which could inhibit foetal growth during further pregnancy (Da Silva et al., 2016). As increased litter size has resulted in a decreased piglet birth weight and increased within litt ...

IntroductionAs the economic success of sow husbandry relies very much, but not solely, on the ability of sows to produce a high number of piglets per sow per year, a high sow litter size contributes to this goal. Genetic selection for higher litter size has resulted in a steady increase in sow litter size in the last decades, and this increase in litter size still continues. For exa ...
