The conversion of straw into biological feed has many advantages. 1 The production time is short. It takes 1 to 3 days in spring, summer and autumn and 3 to 7 days in winter. 2 It is not subject to seasonal restrictions and can be used throughout the year. 3 complete nutrition, good palatability, easy to digest and absorb. The production method is as follows:
First, the choice of straw
Different animal biological feeds can choose different types of straw. 1 herbivorous animals (such as cattle, sheep, horses, donkeys, etc.) can use corn stover, rice straw, wheat straw and other low-nutrition, high fiber and lignin straw; 2 monogastric animals, poultry and fish (such as pigs, Rabbits, ducks, geese, fish, etc.) may choose materials with relatively high nutrient content, relatively low crude fiber and lignin, such as peanut pods, peanut husks, rice bran, wheat bran, etc. as raw materials. Regardless of the kind of straw, roots and soil should be removed first, and the mildew and metamorphic parts should be removed to keep the straw fresh and fresh.
Second, the preservation of straw
During the autumn harvest, dry the straw, classify it and make it into a mortar. Cover it with plastic cloth or other rain-proof equipment to prevent leakage, rain and snow, and store it for a long time.
Third, the production of cattle and sheep biological feed
1, the production of cattle biological feed
1 Cut the straw into a short section of 3 to 5 cm with a rake, or rub it into a filament with a rubbing machine and weigh 75 kg on a clean concrete floor. 2 Take 0.5kg of transforming agent and add it to 75kg of clean water (preferably use 30°C water in winter) to fully dissolve. 3 Spray the aqueous solution of transforming agent on prepared straws that have been cut or rubbed, mixed in plastic bags or other containers, compacted while binding, and finally tightly sealed or placed with plastic cloth. In the shade. 4 After anaerobic fermentation for 1 to 3 days (3 to 7 days in winter), a nutrient-rich, easily digested straw bio-feed was produced. The feed is yellow, with a strong bouquet and malic acid. Avoid exposure to the sun, because the sun's ultraviolet rays have a bactericidal effect, affect the role of beneficial bacteria and enzymes.
2, the production of sheep biological feed
The straw is crushed into 4-6 mm coarse powder or fluffy small pieces are made by a kneading machine, and can be processed according to the above-mentioned method for producing a bovine biological feed.
3, pig, duck biological feed production method
It is best to use peanut pods, soybean meal, rice bran, corn stalks, and peanut husks as raw materials and pulverize them into fine powder of 30 to 40 mesh. The production method is the same as that of cattle and sheep feed.
4. The role of rabbit, fish biological feed
In the case of granulation, without pelleting conditions, rabbit biofeed can also be powdered.
