Fattening method:
1, piglets should be grouped reasonably after 2 months of age. The principle is that piglets with similar age and weight are placed in the same pigsty, and the weight difference does not exceed 10 kg. Because the big pig bullies the little pig, attacks and bites the little pig, causing injury and affecting fattening growth; Piglets are weak, unable to grab food and eat enough feed, which leads to slow growth. If there is a fight between pigs, it should be stopped in time; If a pig is found to attack other pigs frequently, it should be isolated in time.
2. If pigs are not castrated in time, they will be more active and easy to fight because of the role of sex hormones, and will grow slowly after a certain period of time, greatly reducing the rate of return on feed. It is recommended that piglets be castrated at the age of 7 days. After castration, pigs will become docile and easy to manage. The most important thing is that pigs have food and sleep and grow fast.
3. In order to fatten pigs, first of all, we should do a good job of deworming in pig farms. Pig parasite is a nutrient-consuming disease, which we often encounter in pig farms. Pigs eat a lot every day, but they don't gain meat. In fact, this is what parasites are doing. It is suggested that the pig farm should be deworming twice a year, and it can be deworming in spring and autumn every year, because this period is the high incidence area of pig parasitic diseases.
4. Adding 3- 10% fermented blood powder to the pig's diet, after 73 days of feeding, the pig will be slaughtered, and its weight will be more than 100 kg, and the feed cost will be reduced by about 20%.
5. Brush the finishing pigs 1 time every morning and evening, and each time 10-20 minutes. Under the same feeding and management conditions, the weight gain of pigs can be increased by 7.2- 1 1.4%.
6. Collect fresh blood of healthy (or slaughtered) pigs, add 5 ml of anticoagulant sodium citrate per 100 ml, and store at 2℃- 10℃ for later use. Transfusion of 2ml/kg body weight every seven days and regular quantitative intravenous infusion of fattening pigs can accelerate the growth and development of pigs. This method is especially effective for shelf pigs with poor nutritional conditions and become stiff pigs.
7. Triacosanol fattening is especially suitable for middle-aged pigs of 40-50kg, and the average daily gain can reach 0.5-1.2kg, with remarkable effect. Intramuscular injection of triacontanol can increase the daily gain by 24% ~ 35%.
The method is: take 25 grams of triacontanol powder with 80% content, dissolve it in 500 ml of distilled water, sterilize it at high temperature, and inject it every 1 ml of body weight, once every 25 days, and stop injection 4 weeks before pig slaughter.
8. Adding 1-3kg lysine to the pig diet can increase the daily gain of pigs by 15-25% and reduce the feed consumption by 15-20%.
9. Generally, pigs weighing less than 25 kg are fed10g earthworm powder every day, those weighing more than 25 kg are fed 25 kg, and those weighing more than 50 kg are fed 50 kg.
10, Sino-Dutch Novozyme is a compound growth additive. The core technology of AKZO- Novozyme from Holland was introduced by Sino-Dutch Times Biological Company, and the fast-growing preparation was carefully developed and produced with feed Bacillus subtilis as the core raw material, focusing on improving feed utilization rate and promoting the weight gain of growing and finishing pigs. The daily gain of pigs increased by 10% ~ 15%, and the feed cost decreased by 8% ~ 65438. When each pig grows from 10 kg to 60 kg, it only needs half a bag of lotus seeds, which can save 900 ~ 1000 kg of feed. Go out of the market 20 days in advance.
1 1, inject 5- 10 ml of fresh egg white into both sides of the thyroid gland or submandibular gland (feeding point) under the neck of a pig over 50 kg, and vertically inject 3.3 cm. After the injection, the pig likes to sleep but does not move, indicating that the injection is successful. Inject/kloc-0 every 5-7 days, and double the dose. Then feed digestible and nutritious feed, and carefully care for 15-30 days. Pigs can gain more than 0.5 kg on average on the basis of normal weight gain.
