The most obvious effect of Vitamin E/Selenium deficiency in the pig is sudden death, typically in young fast growing weaners, although it can be seen in piglets still on the sow beyond the 3rdweek of life. Two principle presentations can be seen at post mortem examination: 1. Mulberry Heart Disease (MHD). Here the toxic peroxides target heart muscl... See full list on nadis.org.uk The transfer of Vitamin E across the placenta to the developing foetus is generally poor (but better for Selenium) with the piglet relying on Vitamin E transfer in fat particles within colostrum. (Transfer via milk is minimal.) The 'dose' of Vitamin E received in this way must last the piglet until such a time as it is eating sufficient food to sup... See full list on nadis.org.uk Whilst fast growing pigs are most susceptible to MHD/Hepatosis dietetia, a range of other factors should be considered as possible trigger factors: 1. Excessive disease challenge post weaning. 2. Excessive vaccinal challenge post weaning - ensure, where multiple vaccination is needed that veterinary guidance is followed with respect to separation o... See full list on nadis.org.uk This is a highly contentious area with recommended levels frequently found to be inadequate in the field. Typical compound diets nowadays may have the following levels of Vitamin E: 1. Sow diets (lactator and dry sow) 100 iu/kg 2. Creep diets 250 iu/kg 3. Weaner diets 100-150 iu/kg 4. Grower and finisher diets 40-100 iu/kg Selenium levels are norma... See full list on nadis.org.uk Where a problem is identified, additional antioxidants must be provided. Whilst supplementing the diet with additional Vitamin E is the obvious solution, it will take time to work through the system - at least 2 weeks of supplemented feed is needed to restore Vitamin E levels - and the escalating costs of Vitamin E has triggered interest in alterna... See full list on nadis.org.uk Whilst sporadic deaths associated with Vitamin E/Selenium deficiency may be commercially tolerable if growth rates are high, particularly given the escalating costs of supplemental Vit E, there is an obligation on pig keepers to the wellbeing of their charges and to take all reasonable measures to ensure survival. In specific cases of severe proble... See full list on nadis.org.uk The exact mode of action of zinc in the prevention of parakeratosis is not known. Deficiencies of selenium and/or vitamin E can cause sudden death of young, rapidly growing pigs (see Nutritional Myopathy of Pigs). In addition, selenium/vitamin E deficiency in nursing pigs makes them more susceptible to iron toxicosis from iron injections. s winter sets in, many guinea pig owners worry about their furry friends ability to cope with the chilly temperatures.
