How to ferment swill to raise pigs

Pig swill has become a kind of domestic garbage. How can we make full use of it and turn disaster into wealth? This paper briefly introduces the reuse of swill. Swill, also known as swill, as a kind of wastewater in our life, whether in rural areas or cities, especially with the vigorous development of catering industry, swill in hotels is increasing day by day. Hotels, restaurants and schools are continuously exported, but as long as they are fully utilized, they can also have rich returns. Leftovers collected from hotels, restaurants, schools and so on. It has low cost and rich nutrition, and is a good feed for raising pigs. 1. At present, the biggest disadvantages of swill (pig food) are: firstly, the collected swill needs high-temperature disinfection and sterilization, and besides spending a lot of fuel costs, the staff is also very hard. Secondly, the nutrition is also very unbalanced, especially the shortage of plant protein, the relative surplus of animal protein and the poor quality, so the swill market is not fast, which usually takes six or seven months; Thirdly, the components in decanted water are complex, and there are many toxic and harmful substances, which are easy to cause the threat of various infectious diseases and parasitic diseases. Sick pigs and dead pigs occur from time to time, and the risk of loss is great; Finally, it is easy to deteriorate and the preservation time is not long. It is reported that swill fermented into feed has achieved good results in pig industry. Second, the principle of swill fermentation into feed. Using microorganisms, swill can be fermented into safe feed. Nongfukang EM stock solution has made some achievements in this respect. It can not only shorten the slaughter time (from the past six to seven months to less than five months), but also greatly save fuel and labor costs, reduce labor intensity, and achieve or exceed the effect of full-price feed. The raised pigs have rosy skin and bright oil, and the whole pigsty has no peculiar smell and the environment is fresh. Why can it have such a good effect? Taking Nong Fukang EM stock solution as an example, microbial fermentation assistant, also known as microbial starter, refers to a kind of compound microbial inoculum with special "magic" function, which is formed by artificial special cultivation, breeding, purification, rejuvenation and other processes with high-tech methods and means. Among them, the main microorganisms that play a key role are bacteria, filamentous bacteria, yeast, actinomycetes and other "functional" flora ("functional bacteria" can be understood as "functional bacteria"), which is a special microbial starter that meets the requirements of national environmental protection and green food production raw materials. Nongfukang EM stock solution is mainly used for organic wastes such as livestock manure, crop straws, urban and rural domestic garbage, farm slaughter leftovers, garden property area litters, seedlings and flowers leftovers. So that it can be rapidly fermented and decomposed into green pollution-free fertilizer or feed, turning waste into treasure, turning harm into benefit and recycling resources. Nongfukang EM stock solution is the best rapid fermentation assistant for making environmental protection and green ecological fertilizer and nutrient soil for seedlings and flowers. It integrates deodorization, fertilizer making, coarse grains making, disease prevention, environmental protection and safety. 3. The method of fermented swill into feed 1. Ingredients first, drain the swill, and then add other ingredients to reduce the water content to about 60% (that is, it is appropriate to grab it by hand and fall to the ground to spread it).

The reference formula is:

(1) 60-70% of discharged swill;

(2) corn flour10%;

(3) Wheat bran18%;

(4) premix 1-2% (according to the instructions, premix should be added to the fermented feed, and premix can be added to the feed after fermentation);

(5) 0.5% Nongfukang EM culture liquid. 2. After the fermentation, seal the fermentation for one to three days according to the instructions. But containers should be prepared for fermentation: (Fermentation time: generally 2-3 days in summer, 3-4 days in spring and autumn, and 4-7 days in winter. (1) You can use a simple large plastic bag made by yourself to vacuum. That is, after the fermented materials are put into the interior, a large plastic bag cover is put on the outer cover to achieve the effect of complete sealing, and the fermentation is carried out after vacuum pumping. (2) Sealed fermentation in a fermentor is also used. That is to say, build a fermenter first, and the size will be determined according to your own needs. Generally, at least one ton of feed can be fermented, from small to large. The cylinder mouth is cylindrical, and there are water tanks around it. After loading the materials, press a heavy object on it with an iron pot or plastic basin, and then fill the sink with water, so that it can be completely sealed. Please pay attention. It can be fermented in about 3 days. 4. Feeding method: Fermented swill can replace 80% energy feed in the feed formula at most, and feed pigs on this basis. The simplest and most effective method is to mix about 70% swill (depending on the size of the pig) with 30% complete feed. Because there are many kinds of swill, the nutrition of each swill is different, so there is no fixed proportion formula for swill pigs, and everyone should adjust the number according to the growth of pigs in actual operation. 15 ~ 30kg piglets: 30% fermented swill +70% complete feed for piglets. 30 ~ 50kg medium-sized pigs: 50% fermented swill +50% complete feed for medium-sized pigs. 50 ~ 100 kg pig: 70% fermented swill +30% complete feed for pig. Pregnant sows are fed 1 ~ 90 days during pregnancy: 80% fermented swill +20% rice bran, plus green feed. Pregnancy 9 1 ~ lactation period: 40% fermented swill+full feed for big pigs, plus green feed. Breeding boar: 40% fermented feed +30% complete feed for big pigs +20% rice bran+10% wheat bran. The practice of adding green feed proves that even lean pigs have very good effects, and pigs grow rapidly, which can be comparable to complete feed. Pork testing fully meets food standards; Sows grow well and are full of milk, piglets rarely have yellow and white dysentery, and the survival rate is high; Boars are full of energy and their sperm quality is high and good. In addition, the effect of adding Nongfukang EM bacteria liquid directly into daily drinking water is excellent: the ratio of adding it to drinking water is1:200; Several problems that should be paid attention to when using fermented swill to raise pigs are as follows: 1, adopting the principle of small amount first and then gradually increasing, adopting 10% at the initial stage of feeding, and gradually increasing to 30% and 50%; 2. In order to achieve the growth rate basically equivalent to the complete feed, don't be stingy when preparing feed, and reduce the energy and the consumption of protein feed (corn and soybean meal, etc.). ) We recommend that if the energy and protein feed are reduced, pigs may need to be slaughtered for more than 65,438+0 months. Think about how much feed you need to feed 1 month or more. It is better to feed 1 month. Fermented swill is very effective in reducing the cost of sow breeding. 80% can be used boldly during empty pregnancy and early pregnancy to 90 days, and will not cause malnutrition to sows, as long as more green feed is paid attention to. 5. Preservation: Cover the fermented feed immediately after each use, which can be preserved for half a year. When the amount of fermented feed is large, it can be dried in the shade and at low temperature (generally below 80 degrees) to reduce the water content to below 15% and can be stored for a long time (one or two years). It can also be granulated and stored. References:
