When should pigs be fed green fodder.

After early childhood.

1. Methods and precautions for feeding pig green feed. Green fodder, also known as green fodder or green fodder, mainly includes natural forage, cultivated forage, field weeds, vegetable leaves, aquatic plants, young branches and leaves, etc. It is named because it is rich in chlorophyll.

In the process of breeding, the rational use of green fodder can not only save costs, but also effectively improve the efficiency of breeding.

2. When feeding pigs, adding some green fodder can also effectively exercise the digestive function of the pig's gastrointestinal tract, and increase its food intake at the same time, which can effectively promote the healthy growth of pigs. Green feed can be fed directly, or it can be dried and processed into grass powder before feeding, and the effect of mixed feeding is the best. Frequent feeding of pig green feed can make pigs maintain strong appetite, healthy growth, fast weight gain, and delicious meat.

3. Bran mixed fermentation method. Prepare the cleaned and cut raw materials in a ratio of 10 to 1 between the raw materials and the bran. First fill the tank with a layer of green fodder 13 17 cm thick, and then a layer of bran 3 7 cm thick.

In this way, it is spaced apart, compacted layer by layer, and when it is full, water is added after covering the straw curtain and pressing the stone, so that it can submerge the feed 7 10 cm, or mix the green fodder with the bran and compact, layer by layer, and ferment better. Because the bran contains a lot of sugar, it can promote the fermentation of feed, and it can generally be fed to pigs after 3 to 5 days.

4. Improving the digestion of feed is mainly harvested when the green fodder is old and tender before flowering, cultivating the ability of young pigs to eat green fodder, and exercising their gastrointestinal tolerance from an early age. The crude fiber is softened by fermentation, boiling and other processing to improve the digestibility of green fodder.

5. Prevent poisoning. The main thing is to prevent nitrite poisoning. Plants that rot due to bacterial reproduction or improper handling tend to reduce nitrates in the feed to nitrite, and pigs can be poisoned when they eat this feed.

Therefore, it is necessary to pay attention to feeding pigs with fresh green fodder, where it is piled up with heat and mildew or boiled and stuffed overnight, do not feed, use vegetable scraps to feed pigs must pay attention to washing, can be soaked in water for 20 minutes after feeding, in order to prevent pesticide residues.

Pigs are generally not fed much green feed. If you want to be fed green feed, it is recommended to feed green feed before and after vaccination to help reduce stress.

Summary. The answer is being compiled, so please wait.

Pig. Can you eat silage.

The answer is being compiled, so please wait.

Green fodder pigs need to be cooked and fed, and fuel is consumed, and silage can be fed directly to pigs, which reduces the waste of fuel; 4. Silage can maintain the nutrients of green feed to the greatest extent; 5. It can purify feed and protect the environment. Silage can kill germs and insect eggs in green fodder, and destroy the regeneration ability of weed seeds.

Hope it helps, remember to like.

Feed pigs with green fodder, not only save food and commercial feed, pigs also like to eat and grow, but pay attention to the following points when feeding:

First, it should be tender and not old. When the general green fodder is young, it has high nutritional content such as protein, vitamins and minerals, less crude fiber, soft texture, good palatability and easy digestion. Therefore, pigs should be harvested, processed and fed in a timely manner when they are young.

Second, it should be spread out, not stacked. The harvested green fodder should not be stacked. If you can't use it up for a while, spread it out in a cool place.

3. Feed raw rather than cooked. After the green feed is recovered, it can be chopped or pulped and mixed into the mixed feed to feed the pigs directly. However, the green fodder with poor palatability or more crude fiber should be fermented. After 3 to 4 days of fermentation, pigs can be fed.

Fourth, it is necessary to mix feeding, not single feeding. Green fodder should not be fed separately due to incomplete nutrition, but should be appropriately matched with some fine, roughage or mixed feed according to the breed, size, and fat condition of pigs to meet the needs of pigs for a variety of nutrients.

Green feed is one of the important feeds for pigs, with comprehensive nutrition, good palatability, easy digestion, wide range and low cost.

Green fodder is generally composed of three parts: leaves, petioles and stems. The leaves contained the most protein, fat, minerals and vitamins, followed by the petiole and the least, and the indigestible crude fiber content was the highest in the stem, followed by the petiole and the least. Therefore, the nutritional value of the leaves is the highest, and the stems are the lowest.

In the process of collection and transportation, attention should be paid to avoid the shedding and loss of leaves.

The following issues should be paid attention to when feeding pigs with green fodder: (1) The harvest period of green fodder. When it is young, it has a higher content of protein, minerals and vitamins, and less crude fiber, which is easily digested.

2) Green fodder should be fed fresh, not cooked. The cooking process can destroy the nutrients in the green fodder, such as vitamins, and nitrite poisoning can also occur if it is not prepared properly. Therefore, it is best to feed after chopping, beating, fermenting or silage.

3) Green fodder should be kept fresh and clean to prevent mildew, and it should be noted that the green fodder that has just been sprayed with pesticides can not be fed to pigs.

4) Appropriate mix with other feeds. According to the different growth periods of pigs, other feeds are used to ensure that pigs have a variety of nutritional needs.
