Cow manure regeneration feed processing method
After analysis, fresh cow dung contained 22.56% of dry matter, 3.1% of crude protein, 0.37% of crude fat, 9.84% of crude fiber, 5.18% of nitrogen-free extract, 0.32% of calcium, 0.08% of phosphorus, and 13.74% of air-dried sample contained crude protein. %, crude fat 1.65%, crude fiber 43.6%, nitrogen-free extract 22.96%, calcium 1.40%, phosphorus 0.36%. The analysis shows that the crude protein content of cow dung is equivalent to the crude protein content of wheat bran, and the metabolizable energy level is close to the flax cake. The content of calcium and phosphorus is higher than that of alfalfa hay, but the crude fiber content is too high. The cow dung was treated with certain amount, and 10% and 15% of the cow manure regenerate material was added to the diet. The feeding trials of 3 groups of 30 finishing fattening pigs showed that during the 30-day fattening period, the control group The average weight gain of each pig was 12.33 kg, the weight gain of the 10% group was 11.29 kg, and the weight gain of the 15% group was 10.96 kg. Combined with the analysis of the overall economic benefits of the artificial and feed expenses, the actual individual value added of the three groups of pigs was 37.59 yuan respectively. 40.64 yuan and 30.83 yuan, of which the best benefit is the 10% group, so it can be affirmed that adding 10% cow dung to the growth and finishing pig diet will neither affect the normal feeding of pigs nor affect the weight gain. Get better economic benefits. The processing technology of cattle is relatively simple. Here are three processing methods suitable for farmers:
In fresh cow dung, add 0.5% formaldehyde solution (containing formaldehyde 38% to 40%) according to the dry matter mass. Mix well and place for 4-6 hours. If the dry matter content of fresh cow dung is 23%, 115 grams of formaldehyde solution per 100 kilograms of fresh cow dung should be added.
Prepare a fermentation tank, put the fresh cow dung into the cylinder and add 10% to 20% of the energy content of fresh cow dung, such as wheat bran, corn flour, molasses, etc., add water to dilute, seal and ferment for 2 to 5 days. Open cylinder feeding.
After being processed into a viscous mass according to the second processing method, it is treated as early-bubble, late-feed and late-bubble, and can be used to feed livestock on the same day, except that it is dewormed regularly every 10 to 15 days. The first two methods have the same treatment effect.
The cow manure regenerative materials can not only be used as part of the alternative feed for growing pigs, but also can be used as feeds for empty breeding and pre-pregnancy sow breeding, and the added amount can reach 10% to 15%, which is good for improving the performance of breeding sows. effect. At the same time, cow manure regenerating feed can also be used as a substitute for roughage in ruminant diets such as cattle and sheep. It has better biological potency than monogastric animals and has a broad application prospect.
