Embodiment 1
[0026] A feeding method of dynamic nutrition for improving the nutritional metabolism of the pig body, which is the feeding method used in the present invention for the 40kg-70kg stage of the fattening period, and the steps are:
[0027] 1. Select raw materials according to current feeding standards, including corn, soybean meal, wheat, wheat bran, corn DDGS, oil bran, fish meal, calcium hydrogen phosphate, stone powder, lysine 98, soybean oil, baking soda, salt, etc., pre-mixed The feed is composed of copper, zinc, iron, manganese, iodine, amino acids and commercially available vitamins, etc., referring to the current commonly used feeding standards published by the National Research Council (National Research Council, NRC) (1998) and Chinese pig feeding Standard (2004), formulate A1 rations with nutritional levels in the finishing stage of pigs (see Table 2 for details of feed preparation and nutritional levels at different nutritional levels); crude protein (15.87%), crude f...
Embodiment 2
[0037] A feeding method of dynamic nutrition for improving the nutritional metabolism of the pig body, which is the feeding method used in the present invention to raise the 50kg-80kg stage of the fattening period, and its steps are:
[0038] 1. Select raw materials according to current feeding standards, including corn, soybean meal, wheat, wheat bran, corn DDGS, oil bran, fish meal, calcium hydrogen phosphate, stone powder, lysine 98, soybean oil, baking soda, salt, etc., pre-mixed The feed is composed of copper, zinc, iron, manganese, iodine, amino acids and commercially available vitamins, etc., referring to the current commonly used feeding standards published by the National Research Council (National Research Council, NRC) (1998) and Chinese pig feeding Standard (2004), formulate A1 rations with nutritional levels in the finishing stage of pigs (see Table 2 for details of feed preparation and nutritional levels at different nutritional levels); crude protein (15.87%), cr...

Abstract
The invention discloses a dynamic nutrition feeding method for improving nutrition metabolism of pig organisms. The method comprises the steps as follows: A, raw materials are selected, and daily rations A with nutritional levels of corresponding stages are prepared; B, daily rations B with reduced nutrient levels of crude protein, crude fat and salt are prepared on the basis of the step A, and the daily rations B comprise corn, bean pulp, wheat, wheat bran, corn DDGS (distillers dried grains with soluble), calcium hydrophosphate, rock flour, lysine 98, soya-bean oil, baking soda, salt and fodder A and fodder B which are prepared by the crude protein, the crude fat and the salt; C, the pigs are fed with different daily rations in the morning and in the afternoon, and the pigs are fed with the daily rations A during the time period from seven o'clock to twelve o'clock in the morning; and D, feeding is performed twice a day, and the feeding amount of the morning as well as the feeding amount of the afternoon accounts for a half of the total amount of the day. The method is feasible and the operation is simple and convenient; the problems of absorption and antagonism among nutrient substances and the like are avoided, and metabolism utilization of the pig organisms to the nutrient substances is effectively improved; the feeding cost is reduced, the production performance is improved, and the feed reward is increased; and pollution caused by harmful gases such as ammonia gas and the like in air of a pigsty and excreta to the environment can be reduced.
Description
technical field [0001] The invention belongs to the technical field of pig feed feeding, and more specifically relates to a dynamic feeding method of pig feed that improves the absorption, metabolism and utilization efficiency of nutrients by the body, and is suitable for feeding pigs in various stages, especially in the growth period and fattening phase feeding. Background technique [0002] Reasonable feeding standards are the technical standards for the actual feeding work and an important basis for guiding the feeding of pigs. The most influential pig feeding standards in the world are the US NRC and the UK ARC pig feed standards, which have been adopted and used for reference by many countries and regions. In 1983, my country formally formulated "The Feeding Standards for Lean Meat Pigs". In 1987, the National Bureau of Standards officially promulgated "The Feeding Standards for Lean Meat Type Growth-Finishing Pigs." Agricultural Industry Standard - Pig Feeding Standar...
