The pig's early growth stage is dominated by long lean meat and bones. Before 60 kg, the growth of lean meat is in a rising stage; after 60 kg, it is the peak of fat deposition and increase. During the growth of lean meat, pigs need a large amount of protein feed. In the period of fat deposition, the demand for protein from pigs is limited. If a large amount of protein is taken from feed, it will be converted into energy to deposit fat under the skin. This not only reduces the feed conversion rate and causes waste, but also reduces the lean meat rate. Therefore, limiting the quality or quantity of feed at the appropriate time can, on the one hand, maximize the growth potential of lean meat, and on the other hand, it can also control the deposition rate of fat and thus increase the lean meat percentage.
Judging from the practice of breeding, foreign countries usually adopt a rearing system with a total limit of 20 kg. However, in China, due to the difference in pig breeds and feeding conditions, it is more suitable to adopt the limited method after 60 kg.
Pigs restrict feeding and increase lean meat
The factors affecting the lean meat percentage of pigs are mainly breeds and feeds, but the feeding methods cannot be ignored. Pork lean meat and fat have their own growth characteristics, lean meat is mainly constrained by heritability of the breed, and fat is directly related to feed. According to this physiological characteristic, the use of restricted feeding methods is an effective way to increase the lean meat percentage of pigs. There are two specific methods: First, limit food from 20 kg until slaughter; Second, from 60 kg, only 85% of food intake is provided.
