How to reduce the cost of raising pigs: implementing ecological raising of pigs

Raising pigs

In recent years, the high price of feed raw materials such as corn and soybean meal has made the profits of pig farmers getting lower and lower, and the negative impact of "pig loss" has caused strong psychological pressure on pig farmers. reducing costs and losses has become the first choice for most pig farmers.

First, insist on raising a hybrid generation of pigs. The piglets produced by using improved breeds of boars such as Landrace, Duroc and Hampshire with local sows are hybrid pigs with strong vitality, rapid growth and good feeding effect. Therefore, it is necessary to popularize the new technology of "three modernizations" of improved breeding of boars, localization of sows and first generation of piglets.

Second, make full use of rural feed resources and mix feed scientifically. It is necessary to make full use of all kinds of feed resources in rural areas, such as rice, sweet potato, barley, Artemisia mandshurica, vegetables and wild forage grass, so that they can not only ensure nutritional needs, but also reduce the cost of raising pigs. It is estimated that when pigs are fed with mixture, the feed-meat ratio is 2.8 ∶ 1 or 3 ∶ 1, while when pigs are fed with a single corn or rice, each kilogram of corn or rice needs to be consumed for each kilogram gain.

Third, carry out ecological pig raising. In the traditional native method of raising pigs, the temperature and humidity in the pigsty let nature take its course, resulting in high temperature and humidity in summer and autumn and cold in winter, which can not maximize the growth potential of pigs. In addition, without paying attention to environmental hygiene and without measures of isolation and disinfection, pigs are easy to get sick. Most farmers ignore the principle of "prevention is more important than cure", pay attention to the treatment of pig disease, and prefer to spend "big" money on treatment rather than "small" money on epidemic prevention. As a result, farmers suffer heavy losses. Therefore, the piggery can be ventilated and ventilated in summer and autumn, and ventilation facilities can be installed in the pigsty to reduce dampness and prevent heat. Planting vines outside the pig house to shade and cool down to keep the air fresh and the temperature suitable. Popularize the new technology of plastic film greenhouse culture in winter, constantly improve the microclimate of pig houses, and create a good ecological environment for pig growth and development. At the same time, we should also adhere to a strict disinfection system and often clean the environment. Conditional pig houses are equipped with gauze to prevent mosquitoes and flies from biting and reduce the occurrence and spread of epidemic diseases. Regularly do a good job of immune injection of deworming and epidemic diseases, and implement the principle of "prevention is more important than cure". We should strictly control the four major infectious diseases of classical swine fever, swine erysipelas, swine lung disease and paratyphoid fever, reduce the case fatality rate and improve the survival rate and paratyphoid rate.

Fourth, change the hanging frame fattening to straight-line fattening. The traditional hanger fattening is to divide the fattening period of pigs into several stages, and the combination of fine and rough is used to fatten the pigs according to different stages. This method has the advantages of single feed, incomplete nutrition, and can not meet the growth needs of pigs. pigs have the advantages of slow growth, long cycle and low fencing rate. If the piglets after weaning are changed to the fattening pigs before sale, the full-price compound feed and planting forage are used to raise pigs, and the straight-line fattening which gradually improves the nutrition level according to the increase of age can effectively shorten the fattening period and increase the fattening rate.

Fifth, provide adequate drinking water. Water is an important component in animals. Metabolism and various biochemical reactions in vivo can only be carried out with the participation of water. Water deficiency affects the appetite, digestion and normal growth of pigs and reduces the utilization rate of feed. Therefore, it is important to provide adequate drinking water. The method of "free drinking water" is generally used to provide clean and hygienic drinking water for pigs. Especially in the hot summer, the water can not be cut off, and the cold water from the motor well is used to lower the body temperature.

6. Rational use of feed additives. Feed additives contain a variety of essential amino acids, minerals, trace elements, vitamins, auxins, etc., although the amount is small, it plays a great role in the growth of pigs, so the correct and rational use of feed additives is very necessary.

Seventh, self-breeding and self-support. Raising their own breeding pigs, breeding their own hybrid piglets, raising their own commercial pigs, not purchasing piglets, is conducive to epidemic prevention and disease eradication, improve the survival rate of piglets, and reduce the cost of raising pigs.

Eighth, promote high-density pig farming. A finishing pig is raised in a 0.8 square meter pig house in winter and a finishing pig in a 1 square meter pig house in summer. Due to the dense, provincial pig houses and low investment in fixed assets, high-density pig farming not only has few pens and low cost, but also fattening pigs scramble for food, have no activity space, sleep when they are full, love to gain weight, gain weight quickly, shorten the feeding period and reduce the feeding cost.

9. Timely fencing and slaughtering. After more than 90kg, the daily gain rate of fattening pigs slows down obviously, and it is mainly fat precipitation, so it is more and more uneconomical to feed, and the fat meat is increased, and it is not good to sell; less than 90kg is slaughtered, although the feed utilization rate is high, but the meat production rate is low because of low body weight. it's not economical either. Therefore, it is most suitable for general finishing pigs to be slaughtered with 90,120kg.
