Dynamic feeding method for increasing utilization rate of pig feed

Abstract

The invention discloses a dynamic feeding method for increasing the utilization rate of pig feed and comprises the following steps: (A) feeding in the morning: pigs are fed at 7am to 9am, the feeding quantity is about 1-2% of the weight of pigs and the crude protein level of the feed is 15-21%; (B) feeding at noon; pigs are fed at 11am to 13pm, the feeding quantity is about 1-2% of the weight of pigs and the crude protein level of the feed is 13-18%; (C) feeding in the afternoon: pigs are fed at 15pm to 17pm, the feeding quantity is about 1-2% of the weight of pigs and the crude protein level of the feed is 13-18%; and (D) feeding at night: pigs are fed at 18pm to 21pm, the feeding quantity is about 1-2% of the weight of pigs and the crude protein level of the feed is 10-15%. The dynamic feeding method has obvious feeding effects, increases the utilization rate of nutrient in feed, reduces loss rate, effectively increases the growth speed of pigs, the production performance and the feed conversion and increases the average daily gain of pigs by 5.2-13.6%, the cost of feed is lowered, the pollution of harmful gas in the air of hog houses and excrement to the environment is reduced and the aims of saving feed and reducing the environmental pollution of the breeding industry are achieved.

Description

technical field [0001] The invention relates to the feeding of the pig feed utilization rate, and more particularly relates to a dynamic feeding method for improving the pig feed utilization rate. Background technique [0002] In order to grow and develop, produce and reproduce offspring, animals must ingest food from the outside world, and the food of animals is called feed. The nutrients of the feed mainly include 7 categories: carbohydrates, lipids, proteins, vitamins, inorganic salts, water and cellulose. According to a certain physiological production stage of pigs, in order to achieve a certain production level and efficiency, the types and quantities of various nutrients supplied by each head per day or the content or percentage of various nutrients per kilogram of feed are the feeding standards. Reasonable feeding standard is the technical standard of the actual feeding work and an important basis for guiding the feeding of pigs. It can promote the standardization a...

Problems solved by technology

Therefore, feeding a uniform standard ration in the morning and evening will result in insufficient nutrient absorption and utilization and the additional consumption of protein or energy substances caused by mutual transformation between nutrients, and feeding a high-protein ration at night will not only It will cause a certain loss, and it will also lead to an increase in the production of harmful gases such as ammonia in the room

In this way, it will not only cause a huge waste of limited feed resources, increase the feed cost per unit of livestock products, reduce the competitiveness of the breeding industry, but also cause serious pollution to the ecological environment.
