Sow feed selection and control
Sows can be divided into five stages: backup period, weaning period, pre-pregnancy, late pregnancy and lactation. The selection and control of these five stages of feed should be changed according to the condition of the sow. 1, the backup period. The gilts are in the stage of growth and development. High-quality, nutritious feed is essential for the sow's body development and reproductive system development. In the sow feed selection of less than 6 months of age, the large pig material (full-price pelletized material sold on the market) is 1:1 equipped with green fodder and allowed to freely feed. Sows from the age of 6 months to pre-male breeding chose the full-price pellets for sale on the market and 1:1 for green sows. Cottonseed cake, rapeseed cake, and moldy feed that are harmful to the reproductive system are strictly prohibited at this stage. Appropriate feed restriction to prevent sows from becoming overweight, affecting estrus and ovulation. 2, weaning empty period. Empty period refers to the period from normal weaning to pre-breeding. After sows are weaned, they are usually estrus for about a week. Improper selection and control of material at this stage will affect the reproductive cycle of sows. Empty sows often have weaning stress from 1 to 3 days after weaning, which can easily cause mastitis and high fever. At this time, it is important to control the amount of feed fed daily in combination with fattening sows. Two meals a day, quantitative feeding, must not allow them to freely eat and cause these diseases. The feed can not be changed suddenly and should be selected on the market for sale of big pig feed or empty pacifiers. Within 3 days after weaning, the feed material will be gradually replaced by empty feed or big pig feed. Appropriately increase laxative bran and succulent green feed. 3, pre-pregnancy. It refers to 80 days from pregnancy to pregnancy. The control of material at this stage plays a catalytic role in breeding fetuses and increasing litter size. Empty sows continue to limit the amount of feeding after sowing, regular meals, daily feeding 2 to 2.5 kilograms is appropriate (depending on sows fat and thin body conditions), appropriate increase in green feed. After feeding for 20 days, the normal food intake of sows was gradually restored. Do not feed mold, deterioration, freezing, or irritating feed to prevent miscarriage. 4, late pregnancy. It refers to the stage of delivery to the fetus after 80 days of pregnancy. At this stage, the fetus develops rapidly, and calcium and nutrient needs increase rapidly. Poor choice of material can easily cause sow pigs and piglets to be weak and sick. This stage is what is usually referred to as "craving." The feed should be gradually replaced with breastfeeding material, and bone soup should be properly fed. If conditions permit, dry fat or soybean oil can be added to the daily feed. Feeding methods are regular meals, quantitative intake, daily feed to 2.5 to 2.8 kg is appropriate (depending on the sows may be). 5, lactation period. Refers to the stage of sow giving birth to weaning. The selection and control of feed during lactation is the most important aspect of the entire production process. Sows do not feed on calving day, postpartum feed some warm bran soup + biochemical soup pills (3 ~ 5 pills / time) + brown sugar saline, fed twice, to promote the discharge of lochia and rapid recovery of physical strength. On the second day after giving birth, sows are fed about 1 kilogram of feed, and then 0.5 kg of feed is added daily, and the normal amount of food is restored after 4 to 5 days.
