As soon as the colostrum is eaten, the colostrum contains various nutrients and immune antibodies suitable for growing piglets, the most important of which is globulin. It is an indispensable and substituted food for piglets. After the piglet has eaten colostrum, Can get a variety of antibodies, enhance disease resistance, and promote growth and development, if you can not eat or eat enough colostrum can cause piglets hypoglycemia, also known as supercooling, the mortality rate is extremely high, so make each piglet eat as soon as possible Colostrum is the primary condition and the fundamental measure for striving for all-round, full-thickness, uniform growth and healthy development of whole-wooled piglets.
Fixed teat piglets have a habit of fixing teats and sucking teats when they start to eat milk. Once they use the same teat several times, they will be determined until they are weaned. Sows have short postpartum breastfeeding time. To ensure that each piglet has a fixed teat, it is necessary to manually assist in fixing the teats after the piglets are born. Put the weaker ones on the front upper nipple according to the size of the piglets. Slightly strong on the back of the nipples, so that each time the sow put milk, it can be done without milk, can make the nest litter piglets grow neatly.
Strengthen insulation Because the body temperature regulation function of the newborn piglet is not perfect, it is very important to do well in the insulation work, especially in the pig farm where all pigs are born all year long, in addition to strict disinfection, there must be complete insulation equipment.
Iron-supplying piglets often suffer from iron-deficiency anemia due to insufficient iron from breast milk, especially for diarrhea piglets. At the age of 2 to 3 days, 1.5 piglets of each piglet are injected to prevent it. The presence of anemia is very important for raising the survival of piglets and promoting growth and development.
Feeding piglets grow rapidly during lactation, and the source of their nutrients depends mainly on breast milk. Generally, the milk production of sows gradually decreases from 15 to 20 days after delivery. The use of breast milk can no longer meet the nutritional needs of piglets. Therefore, after the birth of the piglets At the age of 5 days, it induced the feeding and feeding, induced the piglet to contact the feed early, exercised the gastrointestinal function, accelerated the development of the digestive organs, promoted the gradual improvement of the digestive glands, and started to eat early, laying a good foundation for early weaning of piglets.
In order for piglets to learn to eat early, they must have good palatability, high nutrient content, and be easily digested. Fresh and clean puffed feeds should be given less frequently. The feed formula should be close to breast milk, sweet and delicious, and piglets love. eat.
Early weaning of piglets
Early weaning of piglets at 21 days of age can not only increase the number of litters per year and the number of litters per year, but also save the sow's peak consumption during lactation. According to the calculation of weaning 7 days in advance, 5 kg of feed was eaten per day, greatly reducing the cost of feed and saving the expenses of artificial water and electricity. The benefits are very considerable. However, early weaning of piglets is a job requiring relatively high technical requirements for raising and management. From birth to weaning, piglets are critical moments for the success of aquaculture production. The quality of feeding and management is directly related to the survival of piglets. In order to ensure the survival of piglets and prepare the basis for early weaning, the author believes that the following points must be done.
