The economic benefits of raising pigs are inseparable from the pig breeds, feed prices, management levels, and market information. How can we raise the economic benefits of raising pigs? This is a key issue that most farmers are most concerned about. What can be done to effectively improve the benefits of pig production?
1, eliminate good drugs. Prior to entry, in addition to the prevention of cold, heat insulation, ventilation, lighting, drainage, moisture, sanitation, and removal of fecal matter, etc., Povidone-iodine or glutaraldehyde must be used. Le, 20% lime water suspension or 20% bleach solution completely sterilize the pen. Only after seven days of disinfection can you enter the pig.
2, choose a good seedlings. Buying a piglet for pigs, choose a binary crossbred pig or a "Dudagrants" three-way hybrid lean piglet from the breed; choose a piglet with a uniform body weight and size from the group; buy it from individuals." The mouth is full of feet, thin hair is white, and it is a robust, lively, willing piglet who eats and moves his feet.
3, with a good party. According to the nutritional requirements of pigs at different stages of growth, feed formulations, pigs grow to 20 kg -35 kg, per kilogram of feed containing digestive energy 3100 kcal -3200 kcal; crude protein 17% -18%; pig 35 kilograms - For 60 kg, per kilogram of feed contains digestive energy of 2900 to 3000 kcal, crude protein of 14% to 15%; for pigs of 60 to 90 kilograms, digestibility per kilogram of feed can be 2900 to 3000 kcal, crude protein 13%-14%.
4, drive insects. Live pigs often come in contact with the ground. Feeding raw materials, they are susceptible to parasites, affect pig development and gain weight, and can cause serious deaths. Therefore, the purchased piglets must be dewormed in vivo. Anthelmintic drugs can use levamisole hydrochloride, albendazole, avermectin, ivermectin and other highly effective anthelmintic drugs, according to drug use instructions, mixed into the feed to feed or intramuscular injection, the drug dose must be accurate to Anti-poisoning or can not achieve the purpose of deworming.
5, good health stomach. After the pigs were dewormed, each piglet was dosed with soda tablets. The pigs were fed into the feed in the morning and fed with gastric lavage. After two days, each piglet was given a dose of rhubarb soda tablets and stomach.
6, play a good needle. After the pigs entered the field, they were observed for 7 days without disease. The pigs were injected with the swine fever vaccine and the pigs were given the paratyphoid vaccine. The pigs were given hoof vaccine 7 days later. After 7 days, the pigs were injected with the highly pathogenic pig blue ear. Disease, 7 days after the injection of erysipelas, porcine pulmonary combined vaccine. After another 7 days, if the pig is normal, pigs were injected with Streptococcus suis. The injection and oral administration of the vaccine are strictly in accordance with the instructions on the label.
7, to a good situation. Both male and female pigs used for fattening must be castrated in a timely manner. After the piglets are castrated, the temperament becomes tame, promotes appetite, increases the speed of weight gain, and improves the quality of the meat. Small boars should generally be emasculated before the appearance of male traits (such as climbing). The gilt should be castrated after sexual maturity, that is, after the first estrous period. It is now advocated to castrate when not weaned and is usually castrated 10-15 days after the piglet is born.
8, a good column. It is uneconomical for pigs to raise more than 100 kilograms without slaughter. From the point of view of the development of pigs, the early growth is fast and the daily gain reaches a peak. After the peak period, weight gain decreased, followed by slow growth or even stagnation. When the finishing pigs weigh more than 100 kg, not only the feed remuneration is reduced, but the energy needed to maintain survival is greatly increased. In general, live pigs live up to 100-110 kg or so slaughter the most appropriate slaughter rate of up to 75%, the net meat rate of 66%, and good economic returns.
