YEAST AND ANIMAL NUTRITION.
. Yeasts vary greatly, not only in their unique genetic strains, but also in the way they are produced, cultured, used and the extent to which they can be beneficial.Live yeast is increasingly used in animal nutrition. It is critical that newborn animals rapidly get colostrum after birth, to provide immunity as well as much-needed nutrients and to ensure a good start in life. In addition to good farm practices and feed formulation, the addition of live yeast to the feed of the mother has positive short as well as long-term effects on suckling animals.The feeding of young animals is fundamental to ensuring their growth and the development of their immune system and also has a significant impact on their future production. Attention must be given to nutrition of gestating and lactating females to ensure that the nutrition of the suckling animal is optimised. In fact, if immunoglobulin transfer from mother animals to their progeny is not sufficient during lactation, growing animals will become very sensitive to pathological issues such as intestinal bacteria inducing diarrhoea. Colostrum (and milk) quality in terms of immune protection and nutritional value will also impact the growth rate of the young animals and then its future growth capacity. To ensure a good transfer of immunity, attention must paid to the immune system of the mother and the immune quality of the colostrum (immunoglobulin content) and on achieving a good intake of colostrum by the newborn (quantity ingested and early ingestion post-partum). A few weeks before giving birth, the immune system of gestating and lactating females has to be well stimulated to have a good synthesis of immunoglobulins, which will then be transferred to the mammary gland. This immunoglobulin content in the colostrum can be very variable depending on different parameters including live yeast supplementation. One way to improve the immunoglobulin content in the colostrum and in the milk is the addition of the live yeast Actisaf (Saccharomyces cerevisiae Sc47) in the feed during gestation and lactation. It has been proven that, following this approach, the immunoglobulin G (IgG) content is increased in the blood of the gestating female and is then transferred via the colostrum and milk to its progeny. In this way, the immunoglobulin content in the blood of suckling animals is significantly increased with a dose-depending effect. Live yeast is a natural way to fight against these diarrhoea in newborn. animals.Achieving an optimal growth rate in newborn animals during the suckling period will increase weight at weaning, positively impacting the future growth of the animals.
