Picking piglets
Pigs of a large scale must choose “Three-way†cross-breeding piglets. It is best to use Changbai and Yorkshire pigs with long waist, wide chest, short mouth, full hips, strong limbs, and fast food. About 90 to 100 kg can be reached, which can shorten the fattening period of 20 to 50 days.
Feeding
After 60 days of age, the piglets should be reared in groups, with 2 to 3 pigs per lap, so as to avoid chasing energy in outdoor pursuits.
Timely castration
The 30-day-old boar and the 40-day-old gilt were castrated and weighed about 15% more than the conventional 60-day-old cast. The wounds healed quickly, shortening the fattening period by about 20 days, and saving about 20% of feed.
Timely deworming stomach
When the piglets are 60 days old, the first insect is driven, and then every 2 to 3 months, the pigs are driven once every 2 to 3 months. According to the weight of the pig, the peristaltic sensitivity of the pig or 15 to 20 mg of anthelmintic insects is used to feed the animals once, and the parasites are repelled. If there is swine fever, 10 g of salt, 10 ml of kerosene, and 20 ml of warm water can be mixed and applied to the surface of the pig to kill insects. At the same time as deworming, 1 kg of quicklime was dissolved in 5 kg of water for each pig, and the supernatant was taken and fed twice a day for 2 to 3 days to remove the various insect pests. One week later, pigs were given a piece of rhubarb soda per kilogram of body weight (maximum no more than 15 tablets), and the stomach was fed in three batches. In this way, each pig can increase the weight of 10 to 15 kilograms and shorten the period of 25 to 40 days.
Scientific feeding
According to the growth and development rules of the early growth of the pig, the fast growth in the middle period, and the slower growth in the later period, in order to obtain a higher feed remuneration, a straight-line fattening method should be adopted to shorten the feeding period and save the feed. At the same time, it is necessary to implement fine, green, and coarse feed mixes, and to implement dry feed for raw feeding; in the number of feeds, two feeds should be taken daily to reduce the consumption of energy and feed due to multiple feedings to stimulate pig movements. Loss of throwing, reducing feed utilization.
Section feeding
Sows empty phase and the first 80 days of pregnancy can be fully based on green fodder, high-quality roughage feed and bad residue feeds, only with 1 kg of concentrate every day. One month before labor, feed 2 to 3 kg of concentrate every day. In this way, the normal development of the fetus is ensured, and the sow can save 60-90 kg of concentrate feed per pregnant fetus.
Timely breeding
Early weaning of piglets at the age of 60 days to 40 to 45 days, this can promote early estrous sows, early mating, shorten the empty period, and relatively save feed.
Prevent disease
In spring and autumn each year, the “three-joint seedlings†are injected into the pigs on time, which can effectively control the three major diseases of swine fever, swine erysipelas, and swine plague, reduce the mortality rate, and relatively reduce the consumption of materials.
Timely slaughter
When the weight of the hog is 20 to 90 kg, the daily weight gain rises linearly. After 100 kg, the growth rate is slow, and the daily weight gain gradually decreases. Therefore, it is better to raise the slaughter to about 90 kg.
After the collection of pathogenic bacteria specimens, the disposable sampling cotton Swab should be completely inserted into the preservation solution to maximize the retention of pathogenic bacteria.
The collected specimens must be fresh and sent for inspection in time to avoid the death of pathogenic bacteria.
It is forbidden to use products with damaged packaging and expired expiration dates to prevent contamination.
Flexible combination: the number and type of swabs and sampling tubes can be combined arbitrarily.
Wide range of uses: It can be used for the collection, transportation and storage of new coronavirus, respiratory virus, hand, foot and mouth virus and other specimens.
Excellent quality: It has been verified by many medical institutions that the virus can still be detected after being stored in the preservation solution for 7 days at room temperature.
Easy to distinguish: the inactivated and non-inactivated preservation solutions are pink, which can effectively avoid sample addition confusion.
