Feeding management of suckling piglets
Grasping feeding and management of suckling piglets can increase their survival rate, promote rapid growth and increase economic efficiency. The feeding of suckling piglets should focus on the following aspects. First, the birth to the 10-day-old piglet feeding 1, the sow's delivery management prenatal production room, the ground, etc. for a thorough disinfection and clean. Disinfect with 10% -20% fresh lime solution. The equipment required for docking and the sows' udder and genitals can be disinfected with 3% to 5% of Lysol solution and wiped clean. After the piglets are born, quickly wipe the amniotic fluid to prevent the amniotic fluid from evaporating and take away the heat, and immediately let the piglets eat colostrum to enhance their ability to keep out the cold. Wind and moisture, before and after noon, let the piglets move in the sun, put some soft grass in the nursery box (basket or bar) inside the circle, and cover the pigs with cloth pieces and regular breastfeeding. 2. After 2 days of postpartum sow feeding, colostrum antibodies gradually decreased. At this time, artificially assist the piglet to eat colostrum, fix the nipple, and let the weak piglet eat more. 3. After birth, the first-born pigs are given gentamicin sulphate injection or streptomycin for the first oral drip, 20 drops (2 to 50,000 units) per head, and once daily afterwards. For 3 days, 0.5 ml of compound norfloxacin suspension was injected through the mouth with a syringe to prevent diarrhea. 4, 3 days old anti-anemia newborn piglets are very susceptible to anemia, it needs to absorb 7 milligrams of iron per day, while only 1 milligram is obtained from the sow's milk. Therefore, from the age of 3 days, use 2.5 grams of ferrous sulfate, 1 gram of copper sulfate, 1 gram of yeast tablets, 1000 milliliters of cold boiled water, mix and dissolve, filter and then give the piglets a drip, giving 3, 5, 7, 10, 15 respectively. Each day-old piglets, 1 ml each time, or three-day-old piglets were injected with 4 ml of iron dextran (50 mg per 2 ml of iron), or sprinkled in the pigsty with fresh and clean red clay soil in the corner of the pig house. Allow pigs to feed freely and prevent anemia. 5 and 7-day-old “pick-to-eat†piglets are generally sprinkled with granules of fritters such as fried soybeans, fried corn, and fried barley on the ground from the 7th day of age, and appropriate amounts of shell powder or bone meal are placed in the feed tank to allow Free to feed, after three days of lure training, 10-15 days of age to learn to eat. 6, 10 days old "open food" will be a small amount of fresh young vegetables mixed with the feed into the feed trough, so that piglets feed freely, and gradually enhance its resistance to rough feeding performance. Second, 10-20 days old piglets 1, early drinking water 3 days old piglets have a thirsty, especially at 10 days of age, if you do not drink water, it will drink some dirty water or urine, can easily cause yellow White lice disease occurs. Piglets should be fed to a feeding room to make them familiar with the environment and to facilitate food intake. 2, to prevent yellow and white rickets so that piglets eat enough colostrum, so that the circle to keep dry and clean, warm, increase mat grass and so on. If yellow and white worms occur, all nests should be treated in time. Intramuscular injection with drugs such as chlorella, berberine, andrographolide, norfloxacin, and gentamicin can also be used. 60 grams of Pulsatilla, 50 grams of Coptis, Phellodendron, Qinpi, and Sophora flavescens, 40 g each, Codonopsis pilosula, and Radix Astragali 65 g each , Dandelion violet, motherwort each 55 grams, 10 grams of licorice, decoction juice fed to sows, piglets sucking milk to achieve control effect. Feeding compound feeds at ages of 3, 20 days When the pigs consume a large amount of feed, they can feed the piglets with the full price of pellets or compound feed and feed it 4-5 times a day, striving to do less feeding and increase the habit of regular feeding. Its feed formula: corn flour 70%, bean cake 10%, bran 10%, fishmeal 8%, bone meal 2%, each piglet feed amount does not exceed 100 grams. Third, the 30-50-day-old piglet feeding 1, grasping piglets "Wang-food" 30-day-old piglets grow faster, there is the phenomenon of snatch and bulimia, enter the vigorous diet, then let the piglets While eating, increase protein and vitamin feeds. In the afternoon of winter, the number and quantity of feedings should be increased in the evening of summer, generally no less than 5-6 times a day. Its feed formula: corn powder 62%, bean cake 15%, bran 10%, rice bran 5%, fish meal 5%, shell powder 1.8%, bone meal 1%, salt 0.2%, the daily feed per pig is 200 Grams around. And to add trace element additives and growth agents, and finally feed green feed to give enough clean drinking water. 2, to prevent skin diseases pigs to keep dry and clean, well-ventilated, ground for grass, so that piglets more sun, keep the skin clean. After the illness, add 1% zinc sulfate to the feed and spray the environment with 0.5%-1% solution of trichlorfon and wipe the affected area with 0.2%-0.5% trichlorfon solution. Normally, 0.04% can be added to the feed with zinc sulfate. . 3, timely castration piglets do not need to stay in castration 30-40 days. Castrated piglets are easy to manage and grow fast. Simultaneously injections of vaccines such as swine fever, swine erysipelas, swine plague, and paratyphoid piglet were used to prevent the occurrence of infectious diseases. 4. Early weaning When piglets are raised to 40 days of age, they can be weaned. Weaning method: One weaning method is prone to indigestion and restlessness of piglets, swelling of sows' breasts, etc. Sow sow drinking water and fine green material should be controlled three days before weaning to reduce milk production. Batch weaning methods: Well-developed piglets were weaned first, followed by weak post-weaning. Gradually weaning method, sow the sow back to the original sty and let the piglets eat milk. The weaning method is gradually adopted. When sows are sucked back into the original pigsty to allow the piglets to eat milk, the number of replacements is reduced day by day, and 3-4 days are sufficient. A feasible weaning method should be selected according to the actual situation. (Source: Rural Practical Scientific Information Zhuoshang Kun)
