Early gestation: maximising embryo viability
Birth weight and homogeneity of the following litter are determined by the quality of the maternal environment as early as pre-implantation. Ovulation and embryonic development are facilitated by the availability of these micronutrients, including selenium.
A study was conducted to determine the effect of selenium on sow reproductive performance depending on the source of selenium: sodium selenite or selenium yeast, Selsaf®, (i.e. organic selenium). Digestibility of selenium yeast is considered to be between 80% and 100% absorbed (with an amount of digestible organic selenium of around 50%). The study shows a positive trend on the litter size. Selsaf® enhances the vitality and homogeneity of the embryos, contributing to better prolificacy.
