Some Experiences in Early Weaning of Large-scale Pig Farm Pigs
November 11 02:01:12, 2018
The early weaning of suckling pigs generally refers to weaning pigs from the 28th to the 35th days after weaning. We have been weaning at the age of 28 days since the establishment of our company. Weaning at 5 days of age. Early weaning of suckling pigs can increase the utilization rate of sows (annual childbirth can be increased from the second child to two to two children), which can increase the annual yield of sows. It can also increase the feed intake of nursery pigs (29 days to 70 days old) and reduce the yellow and white piglets in the nursery period. It has been widely adopted in large-scale pig farms and can improve pig farms better. A good way to economic benefits. Here are some of the practices of our company over the past six years: 1. Sows and suckling pigs feeding: Sows are fed three meals a day, pigs are fed 24 hours from the age of seven days, and sows From the delivery room to within three days after delivery, and the first three days before weaning, the daily feeding amount should be about six pounds. In the fifteen days after delivery, the daily feeding amount should reach a peak, that is, about twelve pounds on a daily basis. ) The feeding amount of the sows in the delivery room should be parabolic (middle high, two low). Second, the temperature control of the house: The most suitable temperature for sows is about 16 degrees Celsius, and the most suitable temperature for suckling pigs is between 15 degrees Celsius and 30 degrees Celsius. In winter, we adopt the method of internal biogas stoves. Keep the temperature around 16 degrees Celsius. The suckling pig adopts the red external light and the 100W light bulb to make the local mini-environment temperature of the suckling pig meet their requirements. In summer, the piggery adopts the exhaust fan and the roof spray method to reduce the temperature, and the sow also sprays the sow during the high temperature period. water. The usual temperature of suckling pigs can meet their requirements. 3. Epidemic prevention: Sows are injected with K88 and K99 vaccines two weeks and three weeks before delivery. Piglets are given anti-vaccine vaccine at the age of 20 days and anti-vaccine vaccine at the age of 28 is used once. Fourth, do a good job in fostering piglets: a, newborn milk, a nest of less than eight to make up the top eight, adjust the time required "born the same day, take the big stay small." b. "Footing pigs" appearing in the rearing period are fostered in sows with a small number of live pigs. (And all the piglets they produce are fed to other sows) and fed feed for twenty hours. c. Smaller suckling pigs at weaning, fostered in the next round of transfer, and earlier farrowing, sows with better growing suckling pigs (cast all their own suckling pigs out). V. Sanitary and Disinfection: Each week, the barns are sterilized and sterilized twice a week. In winter, sunny days are selected. In the afternoon, summer flushing can be increased one or two times a week. Disinfectant formaldehyde, immediate killing, chlorine poisoning alternate use. Sixth, iron supplements, etc.: Milk cut within 24 hours of the birth of teeth, tail, seedlings with pigs forty-eight hours during the milk injection lactone. VII. Adjusting sows in time: In the lactating period, if the sows are found to have little or no special milk secretion and have short-term incurable diseases, they should timely transfer the newly weaned sows. Eight, newborn pigs without anus, should be timely artificial anogenital anesthesia, the specific method is to cut a circular epidermis about 2cm in diameter under the tail root, and then isolated from the rectum end of the pure, split the end of the rectum, and the rectum Fixed on round skin. Nine, other: When piglets are 20 days old, boars are used for castration. When sows are difficult to deliver, they should give birth immediately. When piglets are sick, they should be treated promptly.
Greenhouse Vertical Hydroponics
allows you to grow fresh vegetables and fruits at much higher crop yields and
relatively lower costs. Thus, not only is it a profitable undertaking, but one
which has proven of great benefit to humanity. With Greenhouse Hydroponics,
plants can be raised out of season resulting in better control and higher
yields of crops.
