How the application of antioxidants in pig feed


  Antioxidants that prevent or delay for the preparation of some active ingredients in feed oxidative deterioration and added to the feed.
  Mainly used for containing high fat feed, in order to prevent fat from oxidative rancidity metamorphism, is commonly used in the premix containing vitamins, it can also prevent the oxidation of vitamin.
  Pig feed in oil or fat soluble vitamins, carotenoids and carotenoids and other substances, easily oxidized by oxygen in the air, destroying, the feed nutritional value, palatability variation decreased, and even lead to the deterioration of the feed, animal and peroxide on toxic effect. To add a certain amount of antioxidants in pig feed, can delay or prevent the auto oxidation in feed material.
1, type of oxidant
  Many as feed antioxidants such as ascorbic acid, L-, butylated hydroxytoluene, Ding Oxybenzone, tocopherol, ethoxyquin and other antioxidants for food. As a result of the price factor, used in pig feed antioxidants, currently the most widely used is the ethoxy quinoline, a large number of foreign raw materials used in fish meal, followed by dibutyl hydroxy toluene, butyl hydroxy methoxy benzene.
  In addition, the antioxidant effect of citric acid, tartaric acid, malic acid, phosphoric acid, but not for itself, by blocking the action of metal ions, the metal ions can play a catalytic role, and with the antioxidant can enhance the antioxidation and the effect. At the same time, two kinds of antioxidants, with additive effect.
2, application of antioxidants in pig feed
  Antioxidants in the diet is mainly used in the following aspects: to feed oil, fish, animal slaughter by-products and other high fatty acid content in swine feed raw material, in order to prevent oxidative rancidity of fat.
  For alfalfa grass powder, leaf powder, powder and other carotenoids, carotenoid content high pig feed raw material, in order to prevent the oxidation of the vitamin A and pigment destruction, increase the coloring effect and utilization. For pre mixed feed containing vitamins, prevent the decrease of its activity. Add in with pig feed and other easily oxidized materials, prevent the oxidation of easy oxide damage, improve the utilization rate and its effects, especially in the high fat containing aquaculture feed and pet pig feed.
