Vitamin D deficiency syndromes in swine (I)
Vitamin D is normally produced following skin exposure to ultraviolet-B. Since most piglets (and humans too!) are raised in climate controlled housing and born year-round, direct access to sunshine is often limited, even in the summer. Fortunately, vitamin D can be added to diets to meet the animals' need for vitamin D.
Folic acid affects performance of suckling piglets and sows during lactation
Supplementation with folic acid in the diets of lactating sows increases milk production, improves milk quality and the performance of piglets.
Effect of source and quantity of dietary vitamin D in maternal and creep diets on bone metabolism and growth in piglets
Offspring of sows provided 25-hydroxycholecalciferol obtained a markedly improved vitamin D status.
Bioavailability of dietary cyanocobalamin (vitamin B12) in growing pigs
High amount of dietary vitamin B12 decreases its bioavailability, but could build up whole body reserves.
European Union - EFSA: Scientific Opinion on the safety and efficacy of vitamin B6 as a feed additive for all animal species
Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of pyridoxine hydrochloride, supplied via feed or water, as a feed additive for all animal species.
Evaluation of the effect of increasing dietary vitamin E in combination with different fat sources on performance, humoral immune responses and antioxidant status of weaned pigs
Immune response or triglyceride and cholesterol levels in plasma are influenced by the fat source fed rather than the level of vitamin E in weanling pig.
Assessment of vitamin E levels, selenium levels and presence of viral pathogens as the etiology of mulberry heart disease
The objective of this study was to determine a possible relationship between Mulberry Heart Disease (MHD) and the levels of vitamin E, selenium, and 13 other minerals, in heart and liver tissues, as well as to carry out PCR tests on heart tissues in order to determine the existence of a possible relationship between viral pathogens and MHD.
European Union - Scientific Opinion on the safety and efficacy of vitamin E as a feed additive for all animal species
Following a request from European Commission, the European Food Safety Authority was asked to deliver a scientific opinion on the safety and efficacy of vitamin E as a feed additive for all animal species.
Vitamin E is a well-established micro-nutrient for all animal species. Vitamin E-based additives are globally used in animal nutrition, and have been for decades, to prevent vitamin E deficiency.
Effect of vitamin E source, natural versus synthetic, on serum and tissue alpha-tocopherol concentrations in finishing swine
The ratio of relative bioavailability between natural vitamin E acetate and syntetic vitamin E acetate is higher than the commonly accepted value of 1.36
