Affected by the traditional feeding mode, there are currently eight misunderstandings in different degrees.
Misunderstanding 1: The lighter and more economical pigs. Poorly conceived piglets have low disease resistance. Therefore, we should follow the principle of "having a heavy heart and not holding light," and buy a healthy piglet, spend a little more pig money, and spend less on veterinary drugs. In general, 50 to 60 days old piglets weighing 15 to 20 kilograms are normal.
Myth two: Clinkers are easy to digest. In fact, the pig's digestibility of feed does not have much to do with raw and cooked feed. Many of the feeds are boiled and the nutrients such as amino acids and vitamins are destroyed and the nutritional value is reduced. According to calculations, after the corn flour and rice are cooked, 100 kg is equivalent to the feeding effect of 80 kg of raw material.
Misunderstanding 3: Use the "hanging shelf" method to save feed costs. "Dragon Hanging" refers to the method of feeding concentrated roughage in the early stage of fattening (20-35 kg stage), and supplementing concentrated feed in the later period (60-70 kg stage). This kind of fattening method not only influences the weight gain due to insufficient energy supply, but also reduces the quality of pig carcass because of nutritional imbalance. The correct approach is to balance the nutritional needs of pigs at different times until they are slaughtered.
Misunderstanding 4: Pigs grow bigger and bigger. Rural villages are known as saying that "pig is swollen and people are bloated." Many farmers tend to feed the feed blindly, resulting in waste and disturbance of the digestive system of the pigs, affecting their normal growth. In fact, the feed volume of live pigs should be flexibly controlled according to the size of the pigs, feed intake, etc., and adjusted at any time. The amount of feed is adequately controlled at 89% to maintain its strong appetite.
Myth 5: The bigger the pig is, the more valuable it is. Some farmers are accustomed to raising pigs, thinking that the bigger the pig, the longer it will be. This view is wrong. From the point of view of the pig's development law, the early growth is faster and the later weight gain is slower. Generally, the slaughter is the most cost-effective when the weight is 90 to 100 kg, and the meat quality is good.
Myth #6: Ask a veterinarian for a minor illness. Pigs are susceptible animals and have a high prevalence. Regardless of the size of the illness, it is not appropriate to ask the veterinarian for treatment. Because veterinarians often come into contact with diseased animals, they are very likely to carry bacteria and viruses, and they are not economically worthwhile. The most appropriate method is to provide veterinary equipment (such as syringes, thermometers, tweezers, needles, etc.) and common veterinary drugs (such as analgin, atropine sulfate, penicillin, etc.). According to the pig disease prevention and control manual, careful observation and exploration, and the courage to practice, will soon be able to do "a minor illness does not go out, a serious illness to find a vet".
Misunderstanding 7: Reciprocal treatment of swine disease. Pig disease, especially infectious diseases, is a major obstacle to breeding pigs. Therefore, we must pay attention to the prevention of diseases, and we should always pay attention to: scientific breeding, increase the body resistance of pigs; self-cultivation and self-cultivation to prevent the purchase of pigs when the disease into the disease; strict management, pig farms should decline to visit; immunization, produce antibodies; Regular removal of parasites in the body; strict disinfection, do a good job housing sanitation.
Misunderstanding 8: Extensive operations. Live-breeding is a meticulous task, and it is usually necessary to develop habits of “early, middle, and late†observation and “five seeing†(ie, seeing pigs’ appetite, feces, spirit, sleeping, and fur). Once abnormalities are found, it is timely to take countermeasures.
