How to improve the growth rate of pigs to make pig long fast special effects to increase pig growth, especially we raise fat pigs, and hope that the small pig is fast, in advance, so we will raise pig benefits better. The growth rate of pigs is mainly determined by the three factors of variety, feed and management. Therefore, in order to improve the growth rate of pigs, we must first use a good species, and choose to grow fast, adapt to good binary or three yuan hybrid pigs; In accordance with different growth stages of pigs, feeding a comprehensive compound feed; third is to implement scientific management, master a timely slaughter, out, and larger amplification of the overall benefits. Diet is a source of fattening pig nutrition, which is a material basis for growth and development of fattening pigs. Therefore, it is a key to improving the weight, feed conversion efficiency, and increased economic benefits of fertilizing pigs. Master the energy level of diet. Increase the grant of the food energy, although the weight gain speed and feed conversion efficiency can be improved, it will make the body of fattening pigs have fat; the grain energy level is too low, then the weight is slow, the feed conversion efficiency is too low, generally 10 per kilogram The grain contains 11.93 megawa to 12.50 trillion. To ensure that the supply of proteins and essential amino acids in the diet, the crude protein level should be 12% ~ 16%, the protein and essential amino acid level in the diet, determine the deposition amount of the protein in the pig, so fattening The protein should be higher in the seed pigs, and the growth period after weaning is appropriate, and the fattening period can be appropriately reduced. Guaranteed minerals, vitamins supply levels have more than a dozen minerals, which are mainly considering supply of calcium, phosphorus and salt when combined with diet. According to the test, feeding the calcium-containing diet is compared with the feed to poverty, increase the weight of fattening pigs by 18%, and the amount of weight gain consumption is 13%. In addition, it is 720 grams of fattening pigs based on the criterion of the corn soybean cakes, and the fat fertilizer pigs that have not affected the salt is only 560 grams. It is usually added to the diet to add 0.25% to 0.5%. Calcium is also good, the filling is good, the cost is not much, the feeding effect is very good, and the economic efficiency is also very obvious.

For reasonable, scientific cooperation with diet, you can use Ermei to better improve the growth rate of pigs in pigs. Its packing mixed materials, it is very cost-effective, and its effect is remarkable in the practice of pig pigs, and there is also a disease-resistant effect, raising pig feeding, early stage: greed, sleep, There is less feces; medium period: skin red, porridge, resistance to disease; late period: back, buttocks, weight gain; full range: health, green, no drug disabled. In 2017, he was rated as consumers by Henan TV. The above is how to improve the relevant content of the growth of pigs, more about the welcome to call the website, we will be happy to serve you, exchange pig technology, experience, complement to win, together, let our farmers do well, help Let’s easily raise pigs to make big money!
