Several methods of scientific pig raising
First, the concentrate feed pig:
The cultivation materials such as crop straws and by-products left after the cultivation of the edible fungi can be obtained by the necessary treatment. Generally, more than 60 kg of bacteria are obtained per 100 kg of culture material. Feeding pigs with sputum mixes is better than rice bran and can approach the feeding effect of corn.
1. Mycorrhizal collection. After the edible fungi are harvested, the moldy material and the soil on the culture material are first removed, and the hyphae having a large amount of hyphae and a strong taste are taken out and dried or dried, and then drunk.
2. Fermentation before feeding. Mix well with 40 kg of rice bran per 100 kg of saccharide, then add water. The amount of water added is hand-picked to the water between the finger joints without dripping, and is placed in a closed container (cylinder) for fermentation. When the wine is aroma, the feed can be taken out.
3. Control the dosage. Generally, the bactericidal sugar before fermentation accounts for 10%-15% of the feed, and after fermentation, it accounts for 20% of the diet = 35%, the proportion should not be too large, and it is necessary to mix the feeds with a single feed.
4. Precautions. 1 Always keep the bacteria in order to prevent mildew and deterioration. 2 sputum can be crushed and fed directly to pigs, but the feeding effect is not as good as after fermentation. 3 Each fermentation bacterium should not be too much, it should be used up in 5-7 days.
Second, silkworms and grains to feed pigs:
Silkworm sand contains Xin nutrients and is a good feed for pigs. Scientific use of silkworm to feed pigs can not only raise the cost of feeding by 15%-20%, but also increase the weight gain rate of pigs by 10%-15%. Silkworms should be fed the following points:
1. Collect. The silkworm sand is collected and exposed to the sun, and impurities are removed to prevent mildew. After drying, it is pulverized and stored for use.
2. Processing. Silkworm sand should not be freshly fed. Generally, the smashed silkworm should be soaked in clear water for 2-3 hours before feeding. After it is softened, it can be fed to the pig.
3. Dosage. The amount of silkworm in the feed is 5%-10% of pigs with 25-30 kg of pigs in the growth and development stage; 15% of shelf pigs of 30-60 kg; about 20% of finishing pigs of 60 kg or more.
4. Taboo. 1 Do not feed pigs with mildewed silkworms. 2 Can not be fed separately with silkworm cocoons, otherwise poisoning or even death will occur. 3 adhere to a variety of feed cooperation.
Third, the biogas slurry feed pig:
Feeding pigs with biogas slurry can promote growth, speed up weight gain, save feed, and shorten fattening period.
1. The biogas slurry should be extracted from the biogas tank of normal fermentation gas production. Newly built pools or large refueling tanks can only be taken after one month of normal gas production. Feeding pigs with sick pools or toxic substances can not be used, otherwise the damage is extremely great.
2. The pH of the biogas slurry is neutral, that is, the pH should be maintained between 6 and 7.5. Before taking the liquid, use a wooden stick to spell a few times at the feed port of the pool, and take the middle layer to clear the biogas slurry.
3. After the biogas slurry is taken out, it should be allowed to stand for a period of time, and then mixed with the feed for independent accounting. The time of the biogas slurry should be flexibly controlled according to the temperature, and it is generally suitable for half an hour. When the time is too long, the biogas slurry is susceptible to contamination by bacteria.
4. Feeding pigs with biogas slurry should adopt wet mixing method. After the first water, the water is simmered and the water is supplied throughout the day. The biogas slurry should not be dry or wet, mix well, squeeze it into a mass by hand, and feed it to the raw food. The pig is dewormed before feeding.
The biogas slurry is suitable for feeding fattening pigs. It is good to start feeding at a weight of 30 kg, and 90-110 kg can be slaughtered. Boars and empty sows should not be fed with biogas slurry to prevent excessive growth and affect estrus breeding.
When starting to feed the biogas slurry, the pig should have a period of adaptation, and the dosage should be gradually increased. If the pigs are diarrhea during the feeding process, they should immediately stop feeding the biogas slurry and promptly diagnose and treat them. After diagnosis and disease-free, after the symptoms of diarrhea disappear, the biogas slurry can be re-fed, but it is generally possible to reduce the dosage by 0.2 kg per time.
7. Biogas slurry can only be used as a feed additive, it can not replace the concentrate, and it can only fully play its role under the condition that the feed is adequately nutritious.
