1. Choose piglets
Good breeding pigs are the basis for high efficiency. The excellent breeding pigs include Changbai, Dabai, Duroc, Hampshire, etc. These excellent individuals selected for single, double or triple crossings have a short fattening period and high profitability. Experience from domestic and overseas practice shows that when selecting piglets specifically, body length, chest width, hip fullness, high extremities, bright hair color, heavy weaned piglets, piglets with weaning weight less than 7.5 kg, and most growth rates should be selected. Slower.
2. Feeding technology
According to the growth law of pigs, reasonable breeding methods should be adopted to fully develop its growth potential and obtain higher economic benefits.
(1) Take four reform measures: a. Change cooked food and dilute food into semi-dry feed for raw food. This can avoid the destruction of protein, vitamins, and other nutrients in the process of cooking, and it is beneficial to the secretion of digestive juice and can improve digestibility. The semi-dry and semi-wet material method is that 1 part of the batch material does not use water, allowing it to naturally infiltrate, soaking for 1 hour in the summer, 4 hours in the winter, holding a clump and loosening it. b. Changing the hanger into a straight line Fattening method. Piglets long bones, piglets long skin, medium pig long meat, big pig long fat is the growth of pigs. The traditional hanging racks, just inhibited the growth advantage of the pig, which dragged the growth cycle of the pig, Reduced slaughter rate, and meat fat, poor commercial quality; straight fattening law from beginning to end with feed ingredients, according to the nutritional needs of the pig phase, unlimited supply, promote its long, and improve the quality of meat and improve economic efficiency. c. Changing a single feed into a compound feed is based on the nutritional needs of pigs during the growth phase. d. Feeding large fat pigs for appropriate slaughter. Finishing pigs weighing 90 kg - 100 kg must be promptly slaughtered because pigs After the length of the past, the amount of food was more than 100 kilograms, which was relatively long and slow. Practice has proven that the bigger the pigs are, the more The higher the meat ratio, the lower the feed remuneration and the poor economic efficiency. Therefore, the old habits of raising pigs should be changed so that the slaughter can be done in due time.
3. Regular quantitative feeding
Feed four meals a day: 7 am, 11 pm, 3 pm, 9 pm, feeding on time every day, feeding by 5% of body weight. Moderate hunger and fullness, and no remnants. If it can persist for a long time, it will make the pigs form the habit of eating, pulling, and sleeping, and always maintain a strong appetite and good digestive function, speed up the growth of pigs.
Water is an important metabolite for pig growth. The transmission of various nutrients is inseparable from water. After meals, adequate and clean drinking water should be provided, so that it can be warm in winter and cool in summer, letting it drink.
4. Health and epidemic prevention
Health and epidemic prevention are the key to the success of pig production. At the same time as buying piglets, pigs, erysipelas, pneumoconiosis, and paratyphoid vaccines for piglets are injected on time. It is necessary to pay attention to the quality of the vaccine during the epidemic prevention so that the injection site is accurate and the medication is appropriate. Do a good job in sanitation and disinfection work inside and outside the pig house, focusing on prevention, prevention and treatment. Only in this way can we ensure that pigs are robust and develop normally.
Fast pig technology
Fast pig raising has a simple method of feeding, easy to grasp, saves time and material, saves time, has a fast growing pig, has a high slaughter rate, good economic returns, and has the characteristics of large-scale breeding.
