Tips for fattening pigs, use egg white or citric acid and fattening feed additives

Egg white: each pig is injected with about 5 ml egg white each time, and then injected again 7 days later, which has a good fattening effect. Citric acid: it can increase the feed absorption rate and food intake of pigs, promote the digestive ability of pig intestines, and make pigs eat more and grow faster. Fattening feed additives: the proper addition of fattening feed additives to pig feed can not only fatten pigs, but also regulate intestinal digestion and resistance of pigs.

First, fattening tips

1. Egg white can be used to treat stiff pigs in the breeding process. If the method is used well, the effect is also very significant. Generally, each pig is injected with about 5 milliliters of egg white at a time, and then injected again a week later, which has a good fattening effect.

2. Some citric acid can be added to pig feed, which can promote the food intake of pigs, thus improve the digestion and absorption rate of pig intestines, pigs eat more will make it grow faster, and citric acid can improve the feed absorption rate and food intake of pigs.

3. Good fattening feed additives can improve the effect of fattening and weight gain of pigs. generally, a small amount of fattening feed additives can be put into the feed of pigs, which can not only fatten pigs, but also regulate the intestines of pigs and improve their resistance.

2. Fattening methods of raising pigs

The main results are as follows: 1. Before raising pigs, it is necessary to choose excellent and precocious breeds, which are more important than late-maturing breeds, and can save feed and produce fattening pigs, which can also be used to produce fattening pigs.

2. When raising pigs, the quality of feed and the collocation of food are very important, which have a great influence on the fattening effect, especially the content of protein in daily grain, usually from weaning to body weight of about 50 kg. The content of crude protein should account for about 15-16% of the daily grain. After 50 kg, the content of crude protein should account for about 12-13% of the daily grain, so the content of crude fiber should not exceed about 14% of the daily grain.

3. Reasonable grouping should be carried out in the later stage. Generally, uneven size and strength will occur after fattening feed is fed for a period of time. At this time, groups should be grouped properly according to the size and strength of pigs. Feeding is very important to accelerate fattening.

4. In summer and autumn, too high and too low temperature will affect the weight gain of pigs, which is usually about 3-5% lower than that in spring and autumn, so it is necessary to prevent sun exposure in summer, keep ventilated, and keep the pig house warm in winter. we should also pay attention to the pig house light is not too dim, it is convenient for pigs to have a full rest, which is conducive to the growth and fattening of pigs.

5. In general, small precocious pigs can be fattened when their weight reaches about 40 kg, while large late-maturing pigs can start fattening when they grow to about 50-60 kg, because fattening prematurely is easy to waste concentrate and cannot be fed into big fat pigs, and fattening too late is not cost-effective, usually when pigs are found to have a large appetite, ruddy skin, glossy coat, and sleep after eating. Is the best time for fattening.
