Use non-grain feed to feed fat pigs

The development and utilization of non-grain feed in the aquaculture industry is an effective way to reduce food consumption and improve the efficiency of farming.

Forage grain glutinous rice, string pine vanilla, clover, silkworm grass and so on. The grain stalks are tender, fragrant and nutritious, and can be cut 3 to 4 times a year, with a yield of 14 to 20 tons per mu. At the beginning of flowering, the harvest is air-dried, the leaf contains 28% crude protein, and the stem contains 15% crude protein. All of them are fed with fresh stems and leaves, and the daily weight gain is 0.4 kg. If a small amount of concentrate is mixed, the daily weight gain can reach 0.7 kg.

Aquatic organisms such as water peanuts, water hyacinths, and grasses can be fed to pigs. Water peanuts can be fed either by green feeding or by storage. The grass contains 8.7% crude protein, and contains 13 kinds of amino acids and 8 mineral elements, which are processed into powder and mixed with the ingredients.

Peanut vines, peanut vines, leaves and shells contain more protein. After pulverization, they can be mixed with other raw materials to prepare feed for pigs.

Soybean leaves contain low sugar content and are rich in protein. It can be collected as feed as soon as possible without affecting the yield and quality of soybeans. It is more suitable to collect in the ripening period of soybeans. The collected fresh leaves are removed from foreign matter, chopped freshly, smashed or semi-dried. Feeding accounts for 20-40% of the diet, which does not hinder growth and development.

Corn cobs contain a variety of nutrients, which are much higher than corn stalks. The corn cob can be pulverized into corn cob powder, which can replace about 20% of the feed for pigs.

The leaves, eucalyptus leaves, paulownia leaves, pine leaves, orange leaves and cassava leaves can be fed to pigs.

The culture material of the mushroom cultured with the mushroom culture material contained 8% protein, 1% crude fat, and 1% crude fiber. Remove the coarse and fine soil and moldy material, use a large amount of hyphae, mushroom flavored culture material to dry and smash, add 40% rice bran and appropriate amount of water, and prepare for the fermentation of the tank for 1 to 2 days. Affect meat quality.

The vinasse can be freshly fed or made into a dry feed with a protein content of 27% and a nutritional value comparable to that of soybeans. It is good to mix the proper proportion of energy feed and minerals when feeding.

The chicken manure collects 350 to 400 chickens for 1 day, and adds 2.5 kg of wheat bran, sugar and koji. The water is adjusted to dry and wet, and the hands are kneaded into a mass, which can be loosened and placed in a cylinder or plastic bag. Yellow-green, no odor, then add 25 kg of feed grain, 15 kg of green feed, for 30-40 pigs to eat for one day. Using chicken manure as feed can save 30-40% of feed grain and reduce cost by 20-30%.

Melon peel, vegetable pumpkin, zucchini, watermelon and other melons. The watermelon skin is chopped and fed to the pig. The daily feeding amount is 30%, which can both release the fire and detoxify and increase the growth of the pig. In addition, radish, sweet potato root vine, Chinese cabbage, green vegetables and peel can be fed to pigs.
