Teaching materials The piglets are born 5 days to 7 days with a small amount of material, transferred to a paste with clean warm water, placed in the milking machine or feeding trough, so that the piglets touch the tasting, the trough clean and eliminate the good poison, when the If you do not eat it, you should clean it out and feed it to the sow and clean the feed trough. Under normal circumstances, the daily intake from the 10th to the 13th day is 50g to 70g, the daily intake from the 13th to the 16th day is 70g to 110g, and the daily intake is 17 days to 20 days. The amount is 110g~180g, the daily intake from the 21st to the 28th day is 150g~200g, the high milk is 200g~400g, lasts 5 days~12 days, the total dosage is 4kg/head, Then gradually changed to swine swelled material, so stunted pigs will soon catch up with healthy pigs after feeding. Suckling swine feed Feed directly on the feed chute, eat freely, and supply enough clean drinking water. But before and after weaning, we must control feed intake of suckling pigs, eat many meals and eat less, and avoid eating too much and cause diarrhea due to indigestion. The total volume of suckling pig feed is about 30 kilograms per head. Pig, medium pig, big pig compound feed Feed directly, eat freely, supply enough clean drinking water, and the daily feed intake is generally 3% to 5% of the weight of the pig. Sow pregnancy material After 3 days of mating, strict control of the material, the amount of 1 kg to 1.5 kg per day, to prevent chemical transformation. The sows were restricted to feeding for 92 days before pregnancy and the daily feed was 2.2 kg/head. Feeding too much is prohibited so as to avoid early embryonic death and sows' excess fat. Provide sufficient clean drinking water, do not feed moldy feed, it is recommended when feeding in spring and summer, 1 ton of feed mixed with 1 kg of mold remover. Sow feeding material The sows were pregnant for 93 days until delivery and switched to lactating sows. The daily feeding amount was 2.5 kg to 3 kg/head, avoiding free feeding and reducing 1 kg/day 3 days before delivery. Do not feed on the day of delivery, only feed some brown sugar bran bran soup, feed 1 kg on the 2nd day, 1.5 kg on the 3rd day, then feed 2.5 kg + 0.4 calving heads, and press 1.5 for 1 week before weaning. Kg + 0.4 calving head feed. Special attention should be paid to providing adequate clean drinking water, and it is forbidden to feed mildew, frozen and toxic feed. Gilt feed Before 50 kg of gilts are bred by nursery pigs, 50 kg are fed to gilt stocks. Normal fed gilts have a daily feed of 2.5 kg/head. Over-fat or too thin will result in no estrus or pregnancy. . Feed directly, it is forbidden to feed mildew feed and provide sufficient clean drinking water. Boar compound feed To meet the nutritional requirements during boar mating, the average weight of boars for adult boars ranges from 2 kg to 2.5 kg per day to maintain the boar's body condition, which is not fat, thin, or energetic. In winter, the amount of feeding should increase by 10% to 20%. Feeding methods are usually taken once a day in the morning and evening, direct feeding or dry and wet feeding can be, to provide clean drinking water, matching season, should be added 2 ~ 3 eggs / day to improve libido and semen quality.
Laser distance measure is a very convenient
tool for various types of applications in industries, construction and house decoration.
Laser distance meter is a very useful device which gives accurate measurement
of distance, area and volume especially in large areas such as rooms,
apartments, buildings, real estates, factories, warehouses, infrastructures, gardens,
roads, and many other applications requiring accurate results for distance ,
area and volume measurement.
Trade your heavy tape measure for laser
rangefinder, which let you simply take measurements with one hand. No matter
your job, the laser rangefinder will help you measure much farther, with
greater accuracy and in more situations, saving you money and time.
