1, to ensure that newborn piglets eat colostrum well.
2, pay attention to keep cold. Newborn piglets should be afraid of cold at 30-32℃ 1-3 days, 28-30℃ for 4-7 days, and 22-25℃ for 8-30 days. After a month, they should be kept at room temperature.
3. The key to prevent piglets from red dysentery, yellow dysentery and white dysentery is to do a good job of cleaning. Drug prevention: After oral administration, 0. 1% potassium permanganate solution can be put into drinking water for piglets to drink freely, or turmeric can be added in supplementary feeding for prevention, or 0.4-0.5g of furazolidone per head can be taken orally twice a day, or sulfanilamide 1-2g can be taken twice a day for 3 days. Or chop up one catty of garlic and six ounces of licorice, add one catty of Chinese liquor and soak for 5-7 days, and take 1 ml of raw juice and add 4 ml of water twice a day.
4, take bad in time (open food, supplementary feeding)
Feeding piglets should start at 7- 10, which is beneficial to the growth of piglets and abandons the backward method of feeding piglets in 20 days. It is best to use commercial suckling pig feed and add some high-quality green feed. Don't neglect to give enough clean, clean and fresh drinking water when supplementing materials.
5, timely weaning: 30-40 days weaning is better, and the economic benefits are better.
Second, the feeding of weaned piglets
How to improve the survival rate and accelerate the growth rate of a group of piglets (weaned piglets) by specialized farmers should do the following key technical measures.
1. Before entering pigs, pigsty and utensils should be thoroughly disinfected and cleaned. Disinfect the site with quicklime water, brush the walls with quicklime water, and clean the appliances with water.
2. On the day when the pigs are shipped back, they will be isolated and raised in groups. The method is to separate the pigs with good mental state and active mental state from those with poor mental state for observation.
3. Reasonable feeding. The newly bought piglet has a process of adapting to the new environment because of its reduced resistance due to long-distance transportation. Be sure not to eat at once. Generally, only enough clean drinking water is given on the first day of purchase. Piglets with good mental state can be fed with nutrient-rich diluent and some chopped green feed at night, eat less and eat more meals in a week, and then switch to normal feeding after adaptation. Pigs with poor mental state should be carefully observed, patiently raised, their condition determined and treated by veterinarians in time.
Third, the fattening technology of pigs
1, hybrid pigs must be selected as fattening pigs. Lean pigs are mainly selected as the foothold of pig raising development, which will bring higher economic benefits.
2, use mixed drinks to raise pigs, never feed pigs with a single feed, feed pigs with a single feed (that is, rice), because malnutrition not only wastes feed, but also slows down the growth of pigs.
According to the current situation in our county, pig farmers had better use homemade compound feed. Generally speaking, corn accounts for 20-30%, rice sugar accounts for about 30%, wheat (wheat bran is better) accounts for 15-20%, and miscellaneous grains such as soybeans, sorghum, red chips, 1-3% fish meal and a small amount of minerals are appropriately added.
Conditional professional households can fatten with 50% commercial feed and 50% homemade ingredients.
3. Insect control.
In order to improve the production efficiency and daily gain of pigs, 1-2 deworming must be carried out on fattening pigs.
(1) body surface deworming, commonly used 0.5- 1% trichlorfon solution spray to kill body surface lice, mites and other insects.
② Oral deworming, commonly used drugs are albendazole 5-40mg/kg body weight and levamisole hydrochloride 8mg/kg body weight.
In order to prevent drug poisoning, it is best to find a veterinarian for technical guidance.
4. Control epidemic prevention.
Newly purchased piglets are injected with swine fever vaccine, piglets are injected with typhoid vaccine, conditional piglets are best injected in their nests, and fattening pigs receive veterinary epidemic prevention regularly, which is the key to the success or failure of group pigs. Serious infectious diseases such as swine fever, foot-and-mouth disease and pneumonia can only be prevented, but not treated. The reason why experienced professional households sum up as "the growth rate lies in feed, the key to success or failure lies in epidemic prevention, and the economic benefit lies in price."
