Six ways to reduce pig raising costs
Feed a hybrid pig. Although local native pigs have the advantages of strong adaptability and resistance to roughage, they have a slow growth rate and low feed remuneration. Hybrid pigs born from sows with local breeds such as Duroc, Hampshire, Landrace, etc., are called hybrid pigs, which have strong viability, fast growth, and good feeding effects. Therefore, it is necessary to universally popularize the “three-ization†technology of boar improvement, localization of sows, and hybrid generation of piglets among pig farmers. Feeding compound feed. According to the nutritional needs of pigs in different stages of growth, the full-price compound feed made by combining various raw materials can provide comprehensive nutrition without wastage, and the feed volume can be adapted to the feed intake of pigs and the feeding effect is good. Meat is low. The compound feed must be fed raw and must not be boiled, and must be cooked into wet material (squeezing into a group and releasing it loosely). Do not mix porridge. Implement protective breeding. To improve the microclimate of piggery, the traditional way of raising pigs is to let the temperature and humidity in the pig house conform to nature, resulting in high temperature and humidity in summer and autumn, and cold in winter, which can not maximize the growth potential of pigs. Therefore, summer and autumn can be planted outside the pighouse planting vines cool shade, winter plastic film greenhouses to promote breeding techniques, and constantly improve the microclimate of piggery, while regularly doing a good job of insecticide and epidemic vaccination. Change shelf fattening to straight fattening. The traditional hanging shelf fattening is to divide the pig's fattening period into several stages, and use the fine and rough feed combination to fertilize the fat at different stages. This method has a single feed and nutrition is not comprehensive, can not meet the growth needs of pigs, pig growth is slow, long cycle, slaughter rate is low. If piglets after weaning are changed to pigs before sale, full-price compound feed is used, and linear fattening, which gradually increases the nutritional level of the diet according to the increase of the age, can effectively shorten the fattening period and increase the rate of breeding. Provide plenty of water. The weight of 1/3-1/2 of the pig's body is water. Cell metabolism and various biochemical reactions can only be carried out with the participation of water. Lack of water will affect the appetite, digestion and normal growth of pigs, thus reducing the amount of feed. Utilization rate. Timely slaughter. Hog growth can be divided into three stages: young pigs, medium pigs and large pigs. The average consumption of 1 kg of pigs per stage is 2.5, 2.9 and 5 kg, and when the weight reaches 90-100 kg, the The rate of weight gain was significantly slowed down, with fat deposition as the dominant factor. Therefore, it is uneconomical for pigs to raise more than 90 kilograms, and they are more fat and fat; for slaughter of less than 90 kilograms, although the feed utilization rate is high, the slaughter rate is low because of the small body weight, and it is not economical. The most suitable finishing pigs are 90-120 kg slaughter.
