Straw feed production technology
Straw feed refers to the residual by-products of crops that ripen and mature after harvesting, ie stems and leaves. About 60% of the crop stalks are currently used as fuel and fertilizer. Only about 30% of the crop stalks are used as feed. Many of the stalks are burned in the field during the harvest season, resulting in great waste. The biological method can improve the digestibility and palatability of straw. The treated straw has the same nutritional value as the medium level of forage, and the biological method mainly includes silage method and microbial fermentation method. Silage The crop stalks suitable for silage are mainly corn, sorghum and alfalfa crops. Silage has a special acid odor, good palatability, nutrient-rich, soft and juicy, resistant to storage, dependent on weather and harvest time small. Add urea silage: Add 5kg urea per ton of silage material. When the raw material is loaded, urea is fully dissolved in water to form an aqueous solution, and then uniformly sprayed on the raw material. In addition to urea, 3 to 4 kg of urea phosphate can be added to each ton of silage raw material. This will not only increase the nutrient content of nitrogen and phosphorus in the silage material, but also enable the silage to have a faster acidity level and effectively conserve silage. Nutrition in feed. Sour-enriched silage: When legume silage with less sugar content, such as legume grass, is added with an appropriate amount of acid, it can supplement the deficiency of fermentation acid production and inhibit the growth of spoilage bacteria and mold. Commonly used formic acid, plus 3 kg per ton of grass forage, plus 5 kg per ton of forage legumes, corn stalks generally do not use, use caution not to contact with the skin. Microbial fermentation Adding microbial active and efficient strains (live and dry strains for straw fermentation) to crop stalks and storing them in sealed containers (concrete tanks, pits, tanks, and plastic bags) are cost-effective and widely applicable. Straw micro-storage method: the short straw is spread on the bottom of the cellar, and the thickness is about 20-25 cm, and the bacterial liquid is evenly sprayed. After compaction, 20- to 25-cm straw is further laid, then the bacterial liquid is sprayed and compacted until it is higher than The cellar mouth is 40 centimeters in length, sprinkle salt powder on the top layer evenly, and then seal it with plastic film after compaction. The amount of salt used is 250 grams per square meter. Its purpose is to ensure that mildew deterioration does not occur in the upper part of the micro-feeds. After covering with a plastic film, spread 20-30 cm thick straw on the top, cover the soil 15-20 cm and seal. Micro-storage generally takes 20 to 30 days. It takes longer time in winter. If necessary, warm water can be added to adjust the water content or cover the straw mat to facilitate warming and fermentation. The storage and use of micro-storage straw should also be promptly sealed to prevent Second fermentation. Improve the effect of straw feed Refined rough match. The straw feed has less net energy and a large volume. A single feed can not meet the nutritional needs of the livestock and must be fed with a certain amount of concentrate, such as cornmeal, cake feed and vitamins, and trace element additives. The use of adjustment, not a single. Straw fodder is fed to livestock, but also pay attention to the use of adjustment, do not use a single straw long-term feeding, straw, wheat straw, etc. contain less crude protein, calcium, phosphorus, should be with protein, calcium content more legume straw Feeding can not only meet nutritional needs, but also promote gastrointestinal motility and reduce the occurrence of digestive diseases. Green and coarse with nutrition. Straw diet contains very few vitamins and low phosphorus content. The content of green succulent feed and germinating feed is high. Therefore, when feeding livestock, it should try to match the amount of green and juicy feed such as cabbage leaves and carrots. , carrots and germination feed, etc., to supplement the nutritional needs of livestock and promote the healthy growth of livestock.
