Scientific weight gain methods of raising pigs in foreign countries

Nowadays, the scale of pig farming is getting larger and larger. Whether in rural areas or in cities, there are large pig farms or pig farmers. The breeding technology of pigs has been constantly updated and broken through. The profit point of pigs is in the quality and weight of pigs. In addition to quality, the weight of pigs can be said to be a very important factor. In China, it is not very mature in this respect. Then the following brings you the weight gain technology of raising pigs from abroad, let's learn it together!

Citric acid gain weight

In Britain, many farmers have grasped citric acid, which has a very significant effect on the weight gain of pigs, and citric acid is a chemical extract with its own flavor. Generally, citric acid is used as an additive. Adding citric acid to pig feed can improve the palatability of feed, soften some crude fiber feed, and improve the digestive system and digestive ability of pigs. So that it can better absorb nutrients, on the other hand, it is to improve the feed conversion rate, so that the daily weight gain of pigs can be increased to 216g, so the weight gain of citric acid is very suitable for weaned pigs in the growth stage of 5-10kg. Adding 30g citric acid to one kilogram of feed can have an effect.

Weight gain of calcium formate

In the pig industry in Finland, there is a substance called calcium formate, which was immediately put into pig feed production as soon as it was discovered to have this effect. Finnish researchers combined calcium formate with pig feed. After experiments, it was found that calcium formate was really effective. Later, calcium formate was widely used in production, and farmers added 1.54g calcium formate to the feed within a few weeks after weaning. This mixed feed can increase the growth rate of piglets by 12% or more, making the feed conversion rate up to 4%, and this calcium formate mixed feed can minimize the incidence of piglets. It is a relatively safe and green way to raise pigs to gain weight.

Third, "moving" to gain weight

In the United States, some experienced farmers have found that in the process of frequently changing pig pens, the growth rate of pigs is accelerated, and at the same time, it can also enhance the appetite of pigs, and some pigs who do not move very much also become active, although the effect is very good. But this way should not be too frequent, once a month, each time the size of the pigsty should be about the same size, and the form of breeding should be about the same. Each group of pigs should not be casually mixed with new pigs or replaced at will, which will make the pigs uneasy and difficult to adapt to. In the end, it will not achieve the effect, but will increase the inner pressure and mental state of the pigs, and some may suffer from depression. Even bite fights occur in the new herd.

4. Gain weight with high protein

In addition to citric acid weight gain, Britain has also developed a way to rely on high protein for weight gain. Farmers prepare a high protein diet containing more than 18% crude protein at the beginning of two weeks before sow parturition, and then continue to use this feed until the sow's weaning period can be changed to a common diet with lower protein content, which can not only greatly improve the birth and weaning weight of piglets. In addition, it can not only reduce the prevalence rate of piglets, but also effectively shorten the litter cycle of sows, so as to increase the conception rate and the number of piglets, and greatly improve the reproductive efficiency of pigs.

5. Copper element weight gain

In Japan, farmers use trace elements to gain weight. We all know that copper can improve the metabolic rate of organisms. Mixing antibiotics in feed and feeding pigs with appropriate amount of copper can increase the daily gain of pigs by 6.7% and increase the utilization rate of feed by 2%. The feed containing copper is very resistant to bacteria. It can restrain the invasion and harm of some bacteria to the pig body and ensure the healthy growth of the pig.

These are the scientific weight gain methods for raising pigs abroad. For example, many of the weight gain methods on the Internet are undesirable. We should have a certain ability of judgment. Some methods will make the pig's body abnormal and affect the later growth and breeding. In addition, some weight gain formulations contain some harmful chemical ingredients. I hope you can identify them. So much for the introduction.
