Under the same feeding and nutritional conditions, lean pigs have good fattening performance and high lean meat percentage. As a general pig, it is also possible to improve lean meat production through different feeding methods and methods. The above-mentioned feeding methods, nutritional levels and environmental factors are also applicable to ordinary pigs. In addition, the following methods can be used to increase lean meat:
(1) Choosing piglets: Choosing piglets used for fattening is the basis for ensuring the growth and development and quality of the fattening period. In particular, households raising pigs, often need to choose to buy piglets to the market or sow households, which need to pay attention to the selection of piglets body development are said to be long, the body should be large, high leg, high weaning body. Such pigs are often fast-growing in pigs, have a high feed yield, and produce more meat. On the contrary, the skeleton is small and the body is short-circular, and fat is often deposited in the early stages of growth, and the lean body mass of the corpus callosum is low, and the daily gain is also low. The piglets also need to be physically strong. Their performance is a lively and loving response, gluttonous foods, boldness, seldom disease, smooth fur, cleanliness, elasticity, and rapid growth.
(2) Limiting food feeding: A large number of tests have proved that, especially in the late period of fattening, properly limiting the supply of dietary nutrients or reducing the daily feed intake does not have an adverse effect on weight gain, and can increase carcass lean meat percentage and feed reward. Limiting food intake can be taken in the previous period (65 kg before) not limited to food, that is, free to eat, eat and maintain a strong appetite; late limit intake, late (65-90 kg) is limited to 95% of the normal amount Left and right for the home, adjust the nutrition level appropriately according to the changes of the season. Under the medium nutrition level, the average daily feed intake per head, the control in the previous period is 1.65-1.85 kilograms, and the control in the later period is 2.60-2. .80 kg is more suitable. The results of the trial showed that the first-time food was sufficient to allow the pig to grow and develop, because the early period was a long-muscle stage; after the term diet, it was able to control the deposition of large amounts of fat and increase the amount of lean meat produced without reducing weight gain. In this way, it can achieve the purpose of making the average pig longer.
