How to scientifically use raw distiller's grains to raise pigs
According to the statistical analysis of authoritative organizations, the use of distiller's grains to raise pigs has the following advantages: rapid growth of piglets, saving feed, reducing the cost of raising pigs; increasing the efficiency of raising pigs. However, some methods of feeding the breeding households are improper, often causing the pig to become ill, and the effect is not good, and the "food" is counterproductive. The feeding methods and precautions are as follows:
Small family workshops using traditional brewing techniques, due to low koji activity, backward craftsmanship, and low alcohol production rate (100 kg rice, 40-50 kg of wine), the income benefit is not obvious, with the high-tech gradually Development, has gradually changed to the "new process of high-yield winemaking without cooking raw materials." The process does not require cooking. Has: 1 high output: 1 kg of rice can produce high-quality white liquor 1 kg or low-grade liquor 2-3 kg; 2 good wine quality: natural food, pure grain brewing, good taste, no smell, stamina, good drink Top-notch features. After testing by national statutory departments and expert appraisal, the indicators have reached the national superior grade standards, which has been well received by the masses and has played a certain role in promoting economic improvement in poor mountainous areas. However, in the use of distiller's liquid to raise pigs, the distiller's grains remaining in the raw material brewing process are used for feeding, and most of the households suffer from frequent diarrhea, anorexia, and constitutional deterioration due to improper methods. The reason is to analyze from the basic principles of winemaking:
The wine mainly converts the starch in the grain into sugar through the action of the enzyme, and then converts the sugar into wine by the wine yeast.
In the above analysis of the conversion process, the conclusion is that the higher the wine yield, the smaller the starch content in the distiller's grains. On the basis of the high-tech of raw material brewing technology, the wine production rate can reach 100%. Then, theoretically, the residual distiller's liquor is basically free of starch content. There are only a large number of strain enzymes that grow during the fermentation process, and after high temperature cooking, form a "high protein" component. The pig is a omnivorous animal, and the main source of energy for eating is starch. Therefore, it is not feasible to raise pigs by using the distiller's grains of raw materials, which is equivalent to eating meat without eating every day. Raw distiller's grains must have a certain proportion of energy feed to match, in order to become a full-price feed with a basic balance of nutrition, such as increasing the same amount of corn flour, skin, green feed, etc., in a ratio of 1:1, otherwise Can not play the real effect and role, and even cause poisoning, but because the cost of matching other feeds is too high, many farmers waste a lot of distiller's liquid for this. At present, some companies or units use the tempting slogans such as “pig no cost†to attract customers and sell their products, and profit from them. For these misleading advertisements, readers who are ready to invest in the production of wine must be calmly analyzed and beware of being deceived.
Really low-cost pig raising may wish to try the comprehensive utilization of straw. Specific steps:
1. Take 100 parts of straw powder, 5-7 parts of corn oil, 130-150 parts of warm water (winter), and 1 part of "straw fast fermentation composite conversion agent".
2, the above materials are mixed together and fully mixed, piled up into 0.5 m, the ladder piles around, flattened, covered with plastic cloth to start fermentation.
3. Pay attention to the change of the thermometer. When the temperature rises to 35 °C, it should be flipped. The temperature of the whole fermentation process should not exceed 42 °C.
4, room temperature above 15 °C is appropriate, summer fermentation 6-8 hours, winter fermentation 8-14 hours, straw feed will be fermented and emit a fragrant alcohol flavor, then mixed with raw distiller's grains directly to feed livestock or Granulation.
In the product description of "stalk rapid fermentation composite conversion agent", it is recommended to use proportionally when using "stalk rapid fermentation composite conversion agent". If the recommended feed does not match the self-produced feed of the farmer, the raw materials may be appropriately replaced with each other so that the prepared feed basically meets the standard.
