Bright nutritional reasons for pig skin

The full price of nutrition is a major factor in keeping pigs healthy. The bright fur indicates that the pigs are healthy and free from disease. The full price of nutrients for feedstuffs from a nutritional point of view, including energy, protein, fats, carbohydrates, vitamins, minerals and water are all key factors for pig growth and production. With regard to the requirements of pig energy, protein, fat, and carbohydrates, there have been a lot of reports in the literature, and under normal circumstances, the nutrition provided in the feed should be able to meet the needs of pigs for the above nutrition. I will not repeat them here. Here we discuss the bright nutritional reasons of pig skin for vitamins and minerals. 1 Vitamin 1.1 Vitamin A Pigs can store vitamin A in the liver. This vitamin A can be used when the intake is insufficient. Pig vitamin A deficiency symptoms include poor fur, movement disorders, blindness, and decreased fertility. Symptoms of excessive vitamin A toxicity include coarse coat, scaly skin, hematuria, and blood feces. Therefore, maintaining an appropriate level of vitamin A is very important for maintaining a good condition of the fur. Roche's recommended amount of vitamin A is very different in piglets and finishing pigs, ranging from 5,000 to 40000 Iu. 1.2 Vitamin B2 Pigs lack of vitamin B2 will show rough hair, dermatitis and other symptoms, usually the amount of vitamin B2 in the pig diet can reach 6-8mg/kg to meet the normal needs. 1.3 Vitamin B5 Vitamin B5 deficiency can lead to rough pig skin, skin lesions (scar disease), and scaly dermatitis. Usually the amount of ration in the diet is 30-40 mg/kg. 1.4 Vitamin B6 When the pig lacks vitamin B6, it is characterized by hair disorder, roughness, dermatitis, anemia, etc. It is very important to ensure sufficient supply of vitamin B6 in the diet, especially when the protein and energy levels in the diet increase, the vitamin B6 requirement. It also increased. The usual requirement for vitamin B6 in pig diets is l-2mg/kg. 1.5 Vitamin H The lack of vitamin H in pigs is characterized by rough coat, seborrheic dermatitis, hair loss, coking, dry skin, scarring, and cracking. Usually the amount of vitamin H in the diet is 50-200 μg/kg. 2 Minerals 2.1 Sulphur and sulphur are components of sulphur-containing amino acids that participate in the synthesis of body proteins, coats and various hormones. 2.2 iron piglets iron deficiency anemia showed pale skin, coarse hair, slow growth and other symptoms, usually the amount of dietary supplement 150mg/kg. 2.3 copper deficiency copper lead to poor iron mobilization, poor keratinization and collagen, elastin synthesis worse, high copper (300mg/kg) will make the pig's fur light and black pig manure, but the resulting environmental pollution The problem is worrying. 2.4 The typical symptoms of zinc deficiency in zinc pigs are "incomplete coking" of the skin, rough skin shrinkage, and induration in the shape of a knot. High calcium daily roots can induce and aggravate zinc deficiency in pigs. The usual dietary supplement is 120 mg/kg. 2.5 Symptoms of iodine deficiency and iodine are symptoms of dry skin and brittle hair. In order to maintain the normal growth of the fur, the amount of iodine in the feed was 0.2 mg/kg.
