Cows at home don't like to eat dried corn stalks!

It may be that the dry corn stalks suddenly added are not used to it. -New materials should be added gradually. Second, cut the dry corn stalks short and mix them with some water to make them stick to the corn stalks evenly. If you don't eat it, cut the corn stalks into short pits, store them and ferment them before feeding them.

-Yellow storage and processing technology

This is a method to treat dry corn stalks by microorganisms. Crushing corn stalks to 2 cm ~ 4 cm, putting them in a jar, and stewing them with proper amount of warm water for 2 days. Livestock don't like to eat dry straw, so the utilization rate is not high. Yellow is sour, sweet, crisp and soft after storage, and livestock like to eat it, and the utilization rate can be increased to 80% ~ 95%.

Two. Ammonification processing technology

Ammonification is the most practical chemical treatment method, usually using accumulation method and ammoniation pit method. First, cut the straw into 2cm ~ 3cm long and adjust the water content of the straw to about 30%. Every 100 kg of short straw, 3 kg of urea is dissolved in 60 kg of water, evenly sprayed on the straw layer by layer, stacked layer by layer, and then covered tightly with plastic film. The ammoniation time is 1 week in summer, 2 weeks in spring and autumn, and 4 ~ 8 weeks in winter. Before feeding, take it out and blow it in a cool and ventilated place for more than 10 hour until there is no pungent smell. You can feed it. You don't like it at first, it takes 3 ~ 5 days to get used to it. Ammoniated corn stalk can improve the digestibility of crude fiber and increase crude protein, and contains a lot of amine salts, which is a good nutritional source for gastric microorganisms in cattle, sheep and ruminants. Ammonia itself is an alkalizing agent, which can improve the utilization rate of crude fiber and increase nitrogen. Feeding cattle and sheep with ammoniated corn stalks can not only reduce the consumption of concentrated feed, but also accelerate the weight gain of cattle and sheep.

Three. Alkalization treatment technology

This is also a chemical treatment method. Alkalization treatment of corn stalk with alkaline compounds can open the ester bonds which are unstable to alkali in the cell molecules of corn stalk and make the fiber expand, which is beneficial to the penetration of gastric juice of livestock and improve the digestibility and intake of feed for livestock. Alkalization treatment mainly includes sodium hydroxide treatment (soaking in 1.5% sodium hydroxide solution for 24 hours, taking out, washing and draining, and then feeding. Or spray 100 kg of rice straw and mix with 30 liters 1.5% sodium hydroxide solution, and cure in the tank for 3-4 days before feeding) and lime treatment. Take lime treatment with wide sources and low price as an example. Add 65,438+0 kg of quicklime into 65,438+000 liters of water, stir until it is clear, take supernatant, stir evenly in a jar according to the ratio of solution to feed of 65,438+0: 3, and then slightly compact. In summer, the temperature is high, and it usually takes only 30 hours to feed, and it usually takes 80 hours in winter. Or add 3kg of quicklime or 9kg of slaked lime per100kg of straw, then add 0.5 ~ 1 kg of salt and150kg of water, soak12 ~ 24h, and then take out and feed.
