Gilt scientific feeding tube
The availability and quality of gilt rearing will not only affect the quality and quantity of the first-born, but also affect the subsequent multiple births. Therefore, strengthening the scientific management of gilts is an important way to improve the efficiency of sow feeding.
Before entering the pigs, they should be vacated completely, and the sheds and utensils should be thoroughly washed and then fully sprayed or fumigated with 0.3% peroxyacetic acid or 0.5% strong disinfection agent for not less than 8 days. Pigs and pigs entering pigs can enter the farm after being sprayed with 0.3% peracetic acid on the outside of the pig farm.
Newly-born pigs need less flushing, especially when the weather is cold. Newly-raised pigs may not feed when they are on the meal, but they may feed a small amount at the second meal and eat freely afterwards.
The gilts have been given medical care for 5 days to 7 days when they were first introduced. They can use Banlangen 20g-30g, Bupleurum 10g-15g, Radix Astragali 15g-20g, Licorice 10g-15g, Houttuynia 20 Grams, Qingfei San 10 grams -15 grams, through the heart and even 10 grams -15 grams (more than a day of a pig's dosage) Chinese herbal medicine rotation for health care, a course of treatment for 5 days -7 days; 2 times -3 times of herbal health to enhance immunity.
After the gilts enter the stalls, they should add about 10% piglets and some nutritive additives when feeding. Summer and winter work should be done to prevent heat and cold.
After the introduction of the gilts, the immunization procedures should be developed in accordance with the actual batches and the field, so that immunization against immunizations and the use of dextromethoxazole and other insect-repellent stomachs should be done in a timely manner.
The gilts before 6 months of age should be allowed to feed freely in order to promote development; 6 months to 7 months of age should be appropriately limited; from 7 months of age, each pig should have a controlled daily feed of 1.8 kg to 2 kg. . 7 days to 14 days before mating, the amount of feed should be 1/3 more than usual, and it should be allocated to the estrus in the next period.
If the aphrodisiac sows are over-fed, reduce the amount of feed.
Swine gilts after reaching the main column should be divided into groups, strengths and weaknesses, every 6 days to 7 days. From 5 months to 7 months of age, estrus records should be made and the pig farms should be divided into estrus areas and non-estrus areas in order to facilitate treatment according to circumstances. Six months old and seven months old estrus pigs should be sorted and managed according to the estrus date in weeks.
The starting time for gilts is 230 days old and 250 days old, and the body weight is 120 kg or more. The love period is the second or third period. Premature breeding easily leads to no milk after birth or affects the reproductive performance of the gilts.
The gilts before mating should arrange 2 times of reasonable exercise each week to promote estrus.
