The inclusion of certain fatty acids in the diet of sows during the perinatal period has been shown to have beneficial effects on the development and health of lactating piglets by increasing the production of milk fat and the secretion of immunoglobulins in colostrum ( Sampels et al, 2010).
Likewise, the protein and amino acid requirements of the sow increase markedly towards the end of gestation. The supplementation of the diet with certain proteins results in an increase in the protein content in colostrum resulting in an increase in the average weight of piglets (Zhang et al, 2011).
Suplementing diets with fiber in the last stage of pregnancy can also be beneficial for the production of colostrum (Theil et al., 2014), as an optimal intake of vitamins will improve the immunity of piglets and increase their resistance to infectious diseases. (Wang et al, 2017).
It has also been shown that probiotic supplements promote the growth of beneficial intestinal bacteria, resulting in a better use of nutrients from the food and a reduction of pathogens spread to piglets.
