Whether the pigs can see the benefits, in the general market conditions, it is mainly to see whether the pigs can guarantee the slaughter rate. Especially for finishing pigs, the rate of slaughter is high, the benefit is high, the slaughter rate is low, and the benefit is low. In rural areas, pigs are also raised. Some pig farmers make money while others lose money. The main reason is that many pig farmers have not escaped the backward method of breeding pigs and traditional habits, and the efficiency of raising pigs is not high. I concluded by summing up: If pigs pay attention to species, materials, diseases, and tubes, they will be able to increase the slaughter rate of fattening pigs and gain greater benefits.
(a) species - make full use of the advantages of hybridization
"The boar is on a good slope, and the sow is a good nest." Buying piglets is a great science.
1. For hybrid pigs of 30 kg or more, they were used as fattening objects for commercial pigs to fully utilize the advantages of hybridization. Cross combinations were best for three-way hybrids of good varieties, and three-way hybrids of good soils were also feasible. The facts of the breeding show that: The use of binary cross-breeding pigs can increase the daily weight gain by 15% to 20% compared with purebred pigs, and the tri-ternal crossbred pigs increase by about 25% compared to purebred pigs. At present, most domestic hybrid sows using Landrace and Yorkshire are mated with Duroc boars to obtain the best ternary combination.
2. The selected hybrid pigs were robust, well-balanced, and had thick bones. We must not be sick, weak, or disabled. This is the basis for guaranteeing pig production performance and benefits.
(b) Material - scientific selection of feed
In pig production, the cost of feed accounts for more than 70% of the total cost of raising pigs, and the efficiency of raising pigs depends to a large extent on how to scientifically select feeds. Some pig farmers have little knowledge of feed and there are some misunderstandings in purchasing feed, which affects the benefits of raising pigs. First of all, we must avoid misunderstandings in the choice of materials and, by comparison, look at the ratio of meat to meat, and choose high-quality, high-efficiency feeds. When using premixes or concentrates, they must be formulated with good ingredients and should not be picked up at random so as to meet the nutritional needs of the pigs.
1. Pigs should be used at different physiological stages (suckling pigs, piglets, pigs, pigs, boars, and sows each have their own feeding standards), otherwise it will cause feed wastage or poor pig growth.
2. Piglets should "grab three foods" and "over three levels." Grasping milk food, overgrowth good growth; grasping open food, over good feed off; grab busy food, over good milk off. Piglets should not be fed too full to prevent too much fine material, otherwise it will cause diarrhea and induce edema disease.
3. Do not suddenly change the material. Mix the original material with the new material, gradually reduce the original material, and add new materials. After 5 to 7 days, complete the reloading process.
4. The coarse fiber in the pig material should not be too much, and the green feed should be properly matched to prevent a single feed, so as to avoid nutritional deficiencies and nutritional insufficiency.
(c) Diseases - prevention, prevention and treatment
1. There are many kinds of pig diseases and the cause is complex, but the first cause of death is still infectious diseases, especially swine fever, swine erysipelas, swine pneumoconiosis, paratyphoid pig, E. coli disease. We should adhere to the principle of “disinfection as the priority, prevention as the priority, and prevention and control in parallelâ€. The pig farm should be sterilized at least once every 7 days, and the vaccine should be injected at the right time. Once the sick pig is found, it should be immediately isolated.
2. While paying attention to infectious diseases, we must also be alert to consumptive diseases, because he will cause unnecessary losses to pig farmers, such as parasites, panting, delirium and so on. For newly-introduced piglets, it is best to take insect repellent in the feed for 8 to 10 days to repel insects. When the weight reaches 60 to 70 kg, it can be repelled once.
(D) Management - meticulous management, rational feeding
1. Pigs can only scientifically use feedstuffs under the proper conditions of temperature, humidity, clean ventilation, etc., so that pigs can give full play to their performance and increase feed conversion rate. Otherwise it will cause pig stress, pig resistance and immunity
Decline, increase morbidity and mortality, cause huge losses.
2. Newborn piglets should pay attention to auxiliary breast milk to help them fix the nipple. In general, weak piglets are placed in the anterior middle nipple, and relatively strong piglets are placed in the posterior nipple. Piglets should be fed early and at the same time pay attention to "eat less food" to prevent diarrhea.
3. Feed fattening pigs, dry or wet, and drink freely after feeding. At the same time, the feeding of pigs should follow the principle of "timed ration, first coarse and fine, and uniform feeding."
Management is a science and an art. In the process of raising pigs, only by paying attention to species, materials, diseases, and tubes, and reducing unnecessary waste, pig raising can increase its slaughter rate, and it will bring huge profits to the farmers. Otherwise, the money will come to hand. White disappears.
