(1) To improve the feed transition After the weaned piglet is weaned, it is necessary to keep the original feed unchanged within half a month, so as not to affect appetite and cause disease. Half a month later gradually feed the finishing feed.
Weanling piglets are in the stage of rapid growth and are fed high-protein, high-energy diets rich in vitamins and minerals. Should control excessive feed containing crude cellulose, pay attention to supplements.
(2) should pay attention to the feeding system transition Piglets within half a month after weaning, the number of feedings per day should be 1 to 2 times more than breastfeeding, which is mainly feeding night food, so that piglets are uneasy because of hunger. Each time the amount of feed should not be too much, to 78% fullness, so that the piglets to maintain a strong appetite.
Good palatability feeds help increase the appetite of the piglets. Fried soybeans, black beans. Pea and other rich flavor, you can crush it for ingredients to improve the taste of the feed. Crude rice, corn and other cereal feeds are saccharified by cooking and brewing, which can improve palatability. Sweeteners such as saccharin and stevia can also be used to improve the taste of the feed. In addition, the use of clinker raw materials in combination with feeding can also increase the appetite of piglets.
(3) Pay attention to the environment The first days after weaning piglets are weaned, they often show unrest, squeaking and searching for sows. In order to reduce the anxiety of the piglets, it is best to leave the piglets in the original circle and do not mix the piglets. In the first 3 to 5 days of adjusting the circle, the piglets eat and move together in the same trough and become familiar with each other. According to gender, individual size, eating speed, etc., grouping, each group depends on the size of the pig. Weaning piglets should be allowed to maintain adequate exercise time outside the circle. The inside of the circle should also be clean and dry, warm in winter and cool in summer, and be used for excreting excrement at a fixed location.
(4) To prevent digestive tract diseases in piglets After weaning, piglets are changed from eating breast milk to eating independently. Gastrointestinal maladaptation and indigestion are very likely to occur. Therefore, weaning should be done meticulously for half a month after weaning, and weaning should be properly controlled for the first week of weaning. The amount of feed, if the feeding period is based on feeding, the number of feedings per day during the first half of the weaning period remains the same as that during the lactation period, and then gradually decreases until the 3 months of age can be changed to 4 feedings per day.
(5) To provide sufficient drinking water and keep the health of piglets After weaning, the amount of feedstuffs for feed intake will increase greatly, and sufficient water supply shall be provided to ensure that the drinking water is clean; the dry hygiene shall be maintained in the pens.
(6) Feeding of weaned piglets on large-scale farms. After weaning piglets, they are transferred from the delivery room to the closed bed of nursery pigs. Since the net bed feeding does not directly contact the ground, the contact between the piglet and the ground urine is reduced, which can prevent bacterial infection and reduce occurrence of diarrhea. Therefore, the growth and development of piglets is fast and the feed utilization rate is high. According to tests, under the same temperature environment and feeding and nutrition conditions, the average daily weight gain of the weaned pigs raised on the net bed increased by about 15%, the daily feed intake increased by about 68%, and the feed utilization rate increased by about 6%. And the piglets raised on the netbed are healthy, well-growth and have obvious weight gain.
The net bed is welded with a 6.5 mm diameter steel bar, and the distance between the two bars is 10-12 mm. Mesh area is 240 cm l65 cm. A net bed can feed 12 to 14 piglets. The bottom of the net bed is 30-40 cm away from the ground. Each net bed is provided with one automatic food box and one automatic drinker. The net bed is placed in a closed pig house specially used for piglet breeding, keeping the temperature in the house not lower than 18 °C.
Piglets raised on net beds are usually weaned at 35 days, transferred to piglet nursery, reared on a net bed, and fed on feeding piglets with an automatic feeding box (general protein level is about 20%, digestive energy is 13 to 14 MJ/kg), after 50 days of age (15 days on the Internet), the protein level of feed dropped to about 18%, about the age of 70 days (about 35 days on a net bed), and the weight was 25 to 30 kg. , Transferring to growing pig farms. The entire cultivation process is free to eat, free drinking water.
