At present, pigs are farmed in rural areas and their main feed for pigs is red vines, vegetable leaves, stalks, and corn miscellaneous grains. Some granular concentrate feeds and additives are properly purchased to improve the utilization efficiency of self-produced feeds and prolong their use. At the time, the following methods can be used. 1, silage fermentation. Vegetable green leaves, vines and other green feed, can not eat a pile of perishable, fermented through silage, will not be fed up because of piles of green feed rot and wasted, but also make the feed has a sour juicy features. When silage fermentation, attention should be paid to chopped green feed. 2, beaten smash. Beating is the slurring of the succulent stalks of the green feed to facilitate the chewing of the pig and reduce the energy consumption for digesting the feed. The smashing is to crush the straw, corn, grains, etc., so that the straw is about 1 millimeter, and the corn grain powder becomes powder, which facilitates the feeding and digestion of the pig, thereby improving the feed utilization rate. 3, saccharification treatment. Seed-like feeds contain many starches and can be saccharified to improve palatability and increase utilization. The saccharified feed has a sugar content increased by 8- to 12-fold. The specific treatment method is simple, that is, the crushed seed-like concentrate is packed in the barrel inside the barrel, the thickness is 20--30 cm, and then the 80--90 is used. The hot water in °C is poured into the tub (1 part of concentrate to 2-2.5 parts of water) and saccharified after mixing for 3 - 4 hours. The saccharification temperature is preferably kept at 55--60°C. When the pigs are fed, the saccharified concentrate is mixed with the green roughage and the fed pigs are particularly effective. 4, grain budding. It is the germination of the grain feed. After germination, the content of vitamins, carotene, and riboflavin increased, palatability was good, and the value-added effect was obvious. Especially in the winter and spring season, the use of germinating feeds is a good way to alleviate this contradiction, and it also improves the feed utilization rate. The method is to wash the grain feed with clean water to remove impurities, and then put it into the cylinder or compare it. In a large bucket, soak in warm water of 30--40°C for 24 hours. Change the hot water in the middle. Remove the water droplets after the grains are swollen. Spread out to germinate. The thickness does not exceed 5 cm. The top cover gauze is kept moist. Between 15-25°C, apply 15°C clear water once a day for 1 time. Buds will be able to germinate within 3-5 days. Before the budding has yet to take place, open the gauze and turn it 1- or 2-times. 6- -7 days buds grow to about 10 cm, when the vitamin content is the highest, to use pigs to use high efficiency. 5, softening treatment. The straw is chopped and added with quicklime to soften, generally 100kg of chopped straw roughage, with 3kg of quicklime, plus 200-250kg of water. After soaking for 8 hours, place it on the concrete floor for 20-36 hours before feeding. When using crushed oyster shells, peanut vines, sweet potatoes, etc. to feed the pigs, hot water can be used to make the raw materials soften when the texture is softened, the palatability is greatly improved, and the feed utilization efficiency is improved through the softening treatment.
