Species - make full use of the advantages of hybridization

"The boars are so good, the sows have a good nest." Buying piglets is a big learning.

Hybrid pigs of more than 30 kg are selected as the target of fattening pigs for commercial pigs, and the advantage of hybridization is fully utilized. The hybrid combination is the best for ternary crosses of good varieties, and the ternary crosses of good soils are also good. The facts of breeding show that the use of binary hybrid pigs is 15%-20% higher than that of purebred pigs, and the ternary crossbred pigs are about 25% higher than purebred pigs. At present, the hybrid sows of Changbai and Kexi are used in the country to mate with Duroc boars to obtain the best ternary combination.

The selected hybrid pigs are firm, well-proportioned and have large bones. Resolutely unable to enter the disease, weak, and residual pigs, this is the basis for ensuring the performance and benefits of pig production.

Material - scientific use of feed

In pig production, feed costs account for more than 70% of the total cost of raising pigs. The efficiency of raising pigs depends to a large extent on how to choose feed scientifically. When premixing or concentrating materials are used, the raw materials must be prepared according to the formula, and should not be randomly placed, so as to meet the nutritional needs of pigs.

It is necessary to use the different physiological stages of the pigs (suck pigs, piglets, middle pigs, big pigs, boars, sows have different feeding standards), otherwise it will cause waste of feed or poor growth of pigs.

Piglets need to "grab three foods" and "three passes." That is: catching the dairy food, good growth and closing; grasping the food, and making good feeds; grasping the food, and getting through the milk. Piglets should not be fed too much to prevent excessive concentrate, otherwise it will cause diarrhea and induce edema.

Do not suddenly refuel, you should mix the original material and new material, gradually reduce the original material, and increase the new material, after 5 to 7 days to complete the refueling process.

The crude fiber in the pig material should not be too much, and the green feed should be properly matched to prevent the feed from being single, so as to avoid nutritional deficiency and nutritional insufficiency.

Disease - prevention, disease prevention and treatment

There are many types of swine diseases and the causes are complicated, but the first cause of pig death is still infectious diseases, especially swine fever, swine erysipelas, swine plague, swine paratyphoid, and colibacillosis. The principle of “disinfection as the top, prevention as the first, prevention and control” should be adhered to. The pig farm should be disinfected once every 7 days, and the vaccine should be given at the right time. Once the sick pig is found, the treatment should be immediately isolated.

While paying attention to infectious diseases, we must also be alert to consumptive diseases, because it will cause unnecessary losses to pig farmers, such as parasitic diseases, gasping diseases, paralysis and so on. For new piglets, it is best to mix the insecticides in the feed for 8 to 10 days for deworming. When the body weight is 60-70 kg, the insects can be dewormed once.

Management - careful management, reasonable breeding

Only under the conditions of suitable temperature, humidity, clean ventilation, etc., scientifically select feed, pigs can fully exert their performance and improve feed conversion rate, otherwise it will cause the pig's stress, resistance and immunity to decrease, increasing the incidence rate. And mortality, causing huge losses.

Newborn piglets should pay attention to assisting the breast to help them fix the nipple. In general, weak pigs are placed in the middle nipple, and stronger pigs are placed in the posterior nipple. Piglets should be fed early, and pay attention to "eat less meals" to prevent diarrhea.

Feeding of finishing pigs can be done by dry or wet feeding, and free to drink after feeding. At the same time, the pigs should follow the principle of “timed quantitative, first coarse and then fine, and fed evenly”.
