How to improve the economic benefit of fattening pigs

   (1) strengthen pig health care and reduce mortality: the health status of pigs can significantly affect the fattening time. Under normal circumstances, the mortality rate of fattening pigs is 98%. In order to reduce pig mortality, it is necessary to strengthen the care of weak piglets. Generally, when piglets are transferred, several backup pens are left, isolated and raised, and weak piglets are treated by adding medicine or drinking water, and pigs with no therapeutic value are eliminated decisively.

   (2) reduce feed price, raise island feed reward: fattening pig feed can be purchased on the spot, using computer automatic formula technology, do everything possible to reduce feed cost. Pay attention to the heat preservation of pigs in winter and reduce the feeding density, spray water to cool down, increase ventilation and shade to improve the growth rate in summer.

The picture shows: pig

   (3) reduce waste: waste in pig farms can be seen everywhere, and the waste is summarized as follows:

   1) Feed waste: pigs have different nutritional needs due to different temperatures throughout the year, and the formula used can not be applied all the year round. Using high-protein formula in winter will cause waste of protein; using high-energy formula in summer will cause waste of energy and so on. If we can adjust the formula timely and reduce the feed-meat ratio of the whole group by 0.1, for a ten thousand pig farm, we can save 80, 000 ~ 90, 000 kilograms of feed and more than 100000 yuan a year.

   uses high moisture corn without changing the formula resulting in waste: in autumn and winter, it is often heard that pig farmers report that the quality of premix or concentrate is not good, pigs do not eat long, according to understanding, the cause of slow growth of pigs is not caused by the quality of premix or concentrate, but because of excessive moisture in corn at that time. Due to the low temperature in autumn and winter, the energy requirement of pigs is higher than that in spring and summer, and most of the corn at this time is newly harvested corn, and the moisture content is more than 16%. If the formula is not modified, according to the fixed feeding procedure, there will be a lack of energy, affecting the normal life of pigs. The solution to this problem is to increase the proportion of corn and increase the amount of feed while other raw materials remain unchanged.

Second, in the use of wet corn at the same time, with high-energy feed such as oil, which is suitable for suckling pig feed or piglet feed with high energy concentration.

   does not process feed according to the formula resulting in waste: there are several cases. First, the processing is not over-weighed; second, when there is a lack of a raw material, it is easy to use other raw materials instead of other raw materials; third, the raw materials are inferior, such as using wet corn instead of dry corn, which undermines the rationality of the feed formula.

Affect the feed utilization rate.

   2) Drug waste is mainly caused by the following situations:

Waste caused by uneven mixing of    dosing: this is a common problem. Feed dosing and drinking water dosing are popular methods, gradual dilution and pyramid mixing are rarely used in practice, because users find it troublesome to mix materials on the material truck, ground mixing and water mixing. None of them can mix the feed well, and the waste of medicine is very astonishing.

The waste of improper use of   : adding drugs to the feed of pigs that have refused to eat; supplying drugs in drinking water for drugs that are insoluble in water; using preventive doses for sick pigs in the above three cases have no effect or very poor effect on the treatment, and drug waste is inevitable.

Waste of misuse of    drugs: some people advocate long-term high-dose drug control, many pig farms have achieved good results, this method has been accepted by people. However, the cost of using a large number of drugs increases, and the more important long-term and high-dose use of drugs may lead to an outbreak of disease, which leads to the abnormal phenomenon that suckling piglets are easy to raise but difficult to care for, and that nursing pigs have problems in growth and fattening, and at the same time produce serious drug resistance.

Waste of ineffective boars and sows raised by   : in normal pig farms, sows produce 2.2 babies a year and give birth to more than 10 live piglets. Each boar should be guaranteed to breed 2540 sows. If the pig farm does not meet the target, it is very likely that ineffective breeding pigs have been raised. There are mainly the following kinds of ineffective breeding pigs: sows with long-term non-estrus; sows with repeated recurrent estrus; sows with habitual abortion; sows raised in pregnancy houses but do not return estrus; sows with small litter number or poor lactation; boars with foot and limb disease that can not be used. The breeding of these boars and sows, a waste of manpower, a waste of feed, a waste of barracks, etc., should be eliminated in time.
