First, type and amount Grease feeds include animal and vegetable oils. Animal oils such as lard, beef tallow, and fish oil have a metabolizable energy of more than 33.5 MJ/kg. Vegetable oils such as rapeseed oil, cottonseed oil, and corn oil have low metabolic energy, and are also at 29.3 MJ/kg. In general, the best ratio of fat in broiler diets is 0.5% in the early stage and 5% to 6% in the latter stage. Second, add use method Due to the large viscosity of the oil, it must be heated and melted before adding it. Add less powder, mix evenly, gradually dilute, and finally mix it with the rest of the remaining diet. Avoid mixing the oil directly with additives. Bonded to Joan, can not mix. Sprayers can also be used to evenly spray the grease onto the pellet feed surface. For conditional production of pelleted feed, 30% of the added fat can also be added to the pelleted feed, and the other 70% is sprayed onto the surface of the pelleted feed to increase palatability. Third, should pay attention to the problem 1. Do not use spoilage grease. 2, pay attention to the nutritional balance in the diet. After the oil is added, due to the increase of the energy level in the diet, other nutrients in the feed must be adjusted accordingly, especially to keep the protein energy ratio unchanged. 3, feeding and storage time should not be too long. Storage is prolonged or stored under high temperature conditions prone to rancidity. In general, fat-containing feed should not be stored for more than 7 days in summer and not exceed 21 days in winter. 4. Antioxidants should be added to the feed to prevent rancidity.
