How to manage a large-scale pig farm delivery room
The main focus of the management of large-scale pig farms is to breed pigs, and the important link in the management of breeding pigs is the management of the delivery room. Good management of the delivery room can improve the survival rate of piglets, the uniformity of development, and improve the health status of the herd, so as to improve the production performance of the entire farm and increase the economic efficiency of the farm.
Prenatal preparation
Delivery room clean. According to the mating plan, the breeders will clean the delivery room in advance. To expect the production of female pig houses, especially laboring sows, to clean the interior and exterior environment sanitation, keep them clean, ventilated, dry, warm and strictly sterilized within one week prior to delivery.
Sow prenatal preparation. Feed intake before sows is often reduced, which is detrimental to postpartum recovery and lactation. Therefore, it must be ensured that the feed is suitable for both the nutritional needs of prenatal sows and their palatability. To prevent postpartum mastitis, sows with better body condition, 3 days before delivery, stop using green and juicy feed, reduce 10% to 20% (1 kg per day) of fine feed intake, on the day of birth Do not feed or feed less.
Tools, drugs preparation. After the sow enters the delivery room, it is necessary to prepare production supplies, such as production gloves, sterilized rags, scissors, wash basins, and soap. Prepare medicines that may be used for confinement, such as 5% iodine, oxytocin, and potassium permanganate, and prepare some insect repellent and fly-killing drugs in summer and autumn. Prepare post-natal piglets, such as infrared heat preservation boxes, insulation boards, heat insulation lamps and other heat preservation devices, and electronic scales.
Production
The production personnel always pay attention to observe the performance of pregnant sows in order to make the necessary preparations. If the sows are found to have reduced appetite, restlessness, rapid breathing, and basically stopped feeding, the vulva is red and swollen, frequently urinates, the sides of the tail roots are concave, the breasts are enlarged and bright, and the nipples on both sides are open outwards in a figure eight shape. The last pair of nipples is squeezed by hand and yellow latex is sprayed. This is the symptom of the sow's labor. Usually it will give birth within 2 hours to 4 hours. At this time, pay attention to comfort the sow and stabilize the emotions. You can gently touch the abdomen and let the sow lie down naturally. Gently clean the vulva and the tail with warm water.
During the farrowing period, the newborn piglets are rapidly removed from the placenta and the mucus in the ears, nose and mouth is immediately removed. The piglet is grasped by one hand and the other hand is gently squeezed by the sow's pussy towards the abdomen of the piglet. From 2 to 3 times, the blood in the umbilical cord was allowed to flow into the piglets. The umbilical cord was squeezed with the hand that squeezed the umbilical cord. The umbilical cord was clamped 5 cm to 6 cm from the abdomen of the piglet. The connection was broken and the mother was disconnected. The other hand was used. The piglets' two hind limbs were removed and the umbilical cord was disinfected with 5% iodine. The entire body of the piglet was wiped with a towel and weighed (were advised not to lose 800 grams of weak seedlings). After being sprinkled with misfit, it was placed in an incubator. When you are free to move (usually no more than 10 minutes), immediately help them to eat colostrum. It is best to have one, help one, and ensure that every piglet can eat colostrum as soon as possible. Within 2 days to 3 days, the thin piglets eat the nipples in front of them, the strong piglets eat the nipples in the back, and let all the piglets eat their own fixed teats to ensure that the whole litter of piglets develops neatly.
