Method for feeding pork pigs by adopting precise nutrient formula feed

Abstract

The invention discloses a method for feeding pork pigs by adopting precise nutrient formula feed. The method comprises the following steps: the pork pigs to be bred are classified according to breeds,a plurality of test groups are selected for testing, a maximum growth curve and feed intake of the pork pigs with the breed are measured, a standard daily ration ratio is adjusted according to nutrient demand, energy demand and amino acid demand of the selected pork pigs with the breed, and therefore the precise nutrient formula feed is obtained. According to the method disclosed by the invention, the pork pigs are fed with the precise nutrient formula feed at different stages, so that feed costs are reduced, a using amount of calcium hydrogen phosphate and discharge of harmful substances arereduced, and the method has the effect of facilitating environmental protection.

Description

technical field [0001] The invention relates to the field of modern agriculture and breeding industry, in particular to a method for raising pigs using precise nutritional formula feed. Background technique [0002] The mainstream feeding methods in the modern breeding industry include two kinds of free feeding and restricted feeding. Free feeding can adjust the feed intake and feeding time according to the pig's own hunger and satiety, so as to avoid the loss of food due to improper feeding. caused by hunger or satiety. At the same time, it can also avoid the phenomenon of unbalanced feed intake caused by the coexistence of pigs in the same pen size and individual differences in pig feeding behavior. However, because pigs can ingest feed at any time, pigs will not experience a strong sense of hunger, so they often show appetite Poor, free-feeding pigs have a lower feed intake each time, which is not conducive to the development of gastrointestinal volume, which will affect...

At the same time, it can also avoid the phenomenon of unbalanced feed intake caused by the coexistence of pigs in the same pen size and individual differences in pig feeding behavior. However, because pigs can ingest feed at any time, pigs will not experience a strong sense of hunger, so they often show appetite Poor, free-feeding pigs have a lower feed intake each time, which is not conducive to the development of gastrointestinal volume, which will affect the feed intake during the finishing period and then affect performance. Pigs will inevitably use Part of the feed is taken out of the trough, and as far as the animal is concerned, there is feed in the trough, and under normal circumstances, it will not eat the feed that is spilled on the ground, which will cause a lot of feed waste and cause high costs; restrict feed Feeding is a reasonable arrangement of feeding time and feeding amount, so that the pigs maintain a relatively strong appetite, and it will play a role in promoting the development of the pig's gastrointestinal volume, and restricting feeding has an obvious advantage, that is, it can detect diseases in time For pigs, those who do not eat at the side of the trough must be sick pigs, so it is helpful for breeders to find sick pigs in time and reduce mortality, but restricting feeding will easily lead to unbalanced feed intake of pigs in the same pen, and it will have a negative impact on the breeder. The requirements of the pigs are very high. The breeders have accumulated experience through observation during the feeding process, but they still cannot efficiently and quickly formulate the feeding requirements of different strains of pigs.
