In China's domestic pig industry, although the scale of aquaculture is accelerating, almost 60% of the culture is still based on small-scale breeding. Pig farmers introduce new breeds of pigs from outside each year to renew pig farm blood and raise pigs. Quality. However, some pig farmers have some misunderstandings at the time of introduction, which often leads to unnecessary losses. According to the actual production introduction experience, I will now summarize the relevant aspects of the introduction of breeding pigs as follows: NLe China Feed Industry Information Network - based on feed, service Shelter pens should be cleaned thoroughly three times in advance, and 0.5% The strong disinfectant solution is sterilized by spraying or scrubbing twice, and the isolation must be kept away from the existing herd. Thoroughly disinfect the unloading swine bench and the surrounding area of ​​about 3 meters with a 2% solution of fire alkali on the day before the breeding pig arrives.
Transportation vehicles should be fully cleaned before departure and at the arrival of the pigs, completely disinfected with 2% pyrogenic alkali solution, and rinsed with clean water. Transport pigs are generally divided into two levels of iron bars, according to the size of the pig's body weight column, body weight loaded bottom layer, the weight of the upper layer, and appropriate bedding materials such as sand, sawdust, etc., to prevent the car is too slippery. Prepare a wooden bar during transportation to see if the breeding pig is lying down. Sensitive Changbai and Dabai injections of chlorpromazine hydrochloride before loading the pigs are intramuscularly administered at 1 mg/kg to 2 mg/kg body weight.
Breeding management after breeding pigs on the farm
After unloading and grading pigs arrived at the site, 0.015% poisonous solution was used to spray disinfect the pig's body surface and transport equipment. When unloading the vehicle, you must grasp gently to avoid physical injury. Do not rush into the shed after unloading. You should rest in place for 10 minutes. Use the cloth to slowly hunk into the pig house according to size, breed, and male and female. - 5 heads, boars weighing about 70 kg can also feed 3 heads per head, but boars that are overweight or have crawling behavior should be raised in a single pen.
After the fight is completed, the scent of the pig (such as lavender and air cleaner) should be sprayed on the surface of the pig, and special personnel should be given care for more than 12 hours to prevent the pig from fighting.
After the disease-resistant pigs are picked back, individual pigs are injected with green streptomycin and antongding for three days, two injections per head and two medications per day. If there is no cold or cough after three days, stop the medication. .
Drinking water and breeding pigs do not feed feed within 8 hours and cannot drink water within 1 hour. Let the pig rest for one hour and then use a small number of methods to drink water, that is, each time a small amount of supply, wait for 30 minutes after drinking to drink, to prevent pigs from drinking. At the same time in the water plus some electrolytic multi-dimensional or some anti-stress drugs such as vitamins.
Eight hours after the pigs are fed and the breeding pigs are on the farm, generally 65kg or less of the piglets are fed to the piglets or sow feeds in 3 to 4 feedings, so that they are fed less frequently and fed with green feeds. Three days later, feed 2 kg per head per normal feeding amount. Feed standards should be based on body weight, breeds feed all stages of pig feed, can not feed fat pig feed or pregnant sow feed. The boar feeds the boar material, the sow feeds the nurse material or the gilt material, feeds 3 times a day, and adds some antibiotics (such as oxytetracycline, Zhiyuanjing and amoxicillin) to the feed. Days or so, prevent diarrhea or respiratory diseases. For weights above 90 kg, feeds must be limited and replacements for reserve male and female feeds should be used. If there are no gilts, feeds may be replaced by milk supplies. Add some green feed (eg carrots, alfalfa meal) to the feed.
Insulation heatstroke summer day and night temperature difference is large, night temperature is low, after the pigs are brought back to be kept in the greenhouse pigs, keep the night temperature reached 15 degrees or more, to prevent colds, ventilation during the day to cool down. In summer, gilts can be fed with appropriate amounts of biotin, vitamin C, and baking soda to prevent heat stress.
After 15 days of the timely immunization of the breeding pigs, the breeding pigs should be dewormed first. In the production, ivermectin can be injected subcutaneously at a dose of 0.3 ml/kg body weight and repeated once a week later. Da Bei Nong Nobi is fed with 2 kg per ton of feed for 1 week. Then according to the local epidemics according to the immunization program, first carry out swine erysipelas, swine pneumoconiosis, asthma, swollen nasal immunization (if necessary for antibody level monitoring). More than 70 kilograms of body weight should be boosted by swine fever and foot-and-mouth disease.
It is forbidden to use male boars for training and frequency of use in advance. When the weight reaches 90 kg (6 months of age), the training is started. The boars are sent to the estrus sows to induce their mating. The timid boar will have estrus. The pigs arrive at the barn, and after training for half a month to one month, they can be bred. It is used once a week for 8 months to 12 months, and 2 times to 3 times per week for adults. At the same time, the pigs were allowed to exercise freely for 3 hours a day on the sports ground, and their limbs were physically enhanced.
Single Packed Mottled Waxy Corn
Waxy corn comes in a variety of colours. Some people wonder if waxy corn is a genetically modified product. In fact, it is not. Waxy corn originated in China. It is caused by a genetic mutation. Artificial selection gradually led to the emergence of a type of tannin.
Waxy corn, also known as waxy corn, is sticky corn. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dented corn. Its chemical and physical characteristics are controlled by a recessive gene (wx), which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
Coloured glutinous corn is generally white, yellow, red, purple and black, with white, yellow and purple corn being the basic colours. Purple and white hybrids naturally become purple if the purple gene "beats" the white gene and vice versa, so if the two tie we see white and purple corn. Purple can turn into red and black corn, or as we often say, "red is purple and black is purple". Of these colourful corn, the most common yellow waxy corn is the most nutritious as it is rich in carotenoids...
Currently, the only genetically modified foods sold on the Chinese market are soybean oil and papaya. Waxy maize is a hybrid variety and is not associated with genetic modification. Therefore, it can be concluded that glutinous maize is a hybrid variety and has nothing to do with genetic modification.
Genetic modification is a type of "genetic engineering" in modern science and technology, which makes use of modern molecular biology techniques. Hybridisation is the mating of individuals of different genotypes to produce offspring that are different from the original "pure" breed. In a sense, it belongs to the natural exchange of genes that can occur in nature.
