1. Feed hybrid pigs

Although local pigs have the advantages of strong adaptability and rough feeding tolerance, their growth rate is slow and their feed reward is low. Improved piglets born of boars (such as Duroc, Hampshire, Landrace, etc.). The local sows are called hybrid pigs, which have strong vitality, fast growth and good feeding effect. Therefore, it is necessary to popularize the "three-in-one" technology of hybrid generation of improved boar, localized sow and piglet among pig farmers.

Feeding compound feed

According to the nutritional requirements of pigs in different growth stages, a variety of raw materials are mixed together to make a complete compound feed, which has comprehensive nutrition and no waste. The daily feed amount is suitable for the pig's intake, and the feeding effect is good and the feed-meat ratio is low. Compound feed must be eaten raw, and it is forbidden to cook it. You can mix it into wet mix (knead it with your hands and put it away), but you can't mix it into porridge.

3. Implement conservation tillage.

① Improve the microclimate of piggery. The temperature and humidity in the traditional indigenous pig house are natural, which leads to high temperature and humidity in summer and autumn and cold in winter, and can not maximize the growth potential of pigs. Therefore, vines can be planted outside the pigsty in summer and autumn to shade and cool down, and plastic film greenhouse cultivation technology can be popularized in winter to continuously improve the microclimate of the pigsty. (2) Do a good job in pest control and immunization on a regular basis.

4. Change hanger fattening into linear fattening.

The traditional rack fattening is to divide the fattening period of pigs into several stages, and fatten pigs by combining concentrated feed and coarse feed according to different stages. This method has the advantages of single feed, incomplete nutrition, slow growth, long cycle and low slaughter rate. If weaned piglets switch to full-price compound feed until fat pigs are slaughtered, and the nutritional level of diet is gradually improved according to the growth of age, the fattening period can be effectively shortened and the slaughter rate can be improved.

Provide enough drinking water.

The weight of 1/3 ~ 1/2 in pigs is water, and cell metabolism and various biochemical reactions can only be carried out with the participation of water. Lack of water will affect the appetite of pigs and reduce the utilization rate of feed.

Timely slaughter

The growth of pigs can be divided into three stages: young pigs, middle pigs and big pigs. For every weight gain 1kg, the average feed intake of pigs at each stage was 2.5 kg, 2.9 kg and 5 kg, respectively. When the weight reached 90 ~ 100kg, the growth rate slowed down obviously, mainly due to fat deposition. Therefore, it is more uneconomical to raise more than 90 kilograms of pigs, with more fat; Although the feed utilization rate is high, the slaughter rate is low because of the small weight, which is not economical. Generally, 90 ~ 120 kg slaughter is most suitable for fattening pigs.
