Improve the survival rate of piglets
The number of piglet deaths accounts for most of the total deaths. To improve the survival rate of piglets, it is necessary to strengthen management to prevent the death of piglets. Within one week after delivery, the piglets are physically weak, inflexible in action, uncomfortable with the complex external environment, and the sows are post-natally fatigued, slow in movement, or poor in motherhood, and are therefore easily crushed to death. Anti-pressure measures include the following:
First, cut off the piglets tusks: When piglets are breastfeeding, often because of competition for nipples, sharp tusks bite the sow nipples or piglet cheeks, causing sows to rise unrest, resulting in squeezing piglets. Therefore, after the birth of the piglet, the cavities of the piglets should be cut off and the cut section should be kept flat.
Second, keep the environment quiet: to make a noise, from low to high, gradually increase, increase adaptability, to prevent sudden sound, to avoid the sudden surprise of the sow, step on the piglets.
Third, set up nursery or nursery guard bar (frame): In the pig's side or corner, separated by wood bars, iron railings or brick walls, set nursery (width of about 70 cm, about 2 meters can be) There are piglets in and out, and the grass is covered with soft grass. The newborn piglets are used as pressure-proof insulation and later used as a feeding room. After the piglet is born, it is placed in a nursery room and an infrared light bulb is used to warm it up and rest. After every 1-1.5 hours, the baby is breast-fed. After 2-3 days of training, piglets can develop habits of free access. In this way, mothers are separated and breast-feeding at regular intervals, so they can keep warm and prevent pressure.
Some sows are bulky, unresponsive, or have poor motherhood. They are easily crushed to death when they are lying down, especially if the newborn is more likely to be crushed. For this purpose, a nursery bar (shelf) can be installed 27 cm away from the wall and the ground on the sides of the pig bed with iron pipes or round logs to prevent the sow from squeezing the piglet while lying down on the wall.
