What is the best weaning age for piglets? What must I pay attention to after weaning?

With the popularization of scientific breeding technology in large-scale pig farms, according to the environmental factors of pig farms in different regions, the optimal age of weaned piglets has also caused controversy. The weaning date of traditional local breeds of piglets is usually 35~55 days. Obviously, the weaning date is not suitable for the development of modern pig industry. Some people think that the weaning age of imported piglets is 2~4 weeks, 14~35 days, and it is suitable for weaning when the weight reaches 4.5 kg. In the actual management of pig farms, taking into account the planned production level and tasks during the year, early weaning can shorten the reproductive cycle of sows and increase the number of piglets.

In addition, according to practical research, it takes 28 days for sows to recover their postpartum body and reproductive system, and normal estrus can be achieved after weaning for 4 days. At this time, the uterus of mating sows can be effectively rested and recovered, which is helpful to the quality of pregnancy and delivery. Therefore, most piglets are weaned in 24~25 days after delivery, and if the weather is cold, it will be appropriately extended to 28 days, which will help the postpartum uterus of sows recover completely, maintain high sow production function, feed more breast milk to piglets and ensure more adequate development.

The daily feeding amount of weaned piglets should be maintained for one week, and then gradually transferred to weaned piglets to avoid the pressure of weaning materials. At the same time, in order to control the feed intake of piglets during this period, it is generally appropriate for 80% people to eat enough and eat less, and then gradually transfer to the free feeder. Keep the house clean, cool and ventilated on any day, and remove the remaining materials in the tank in time to prevent fungi or infection.

When a sow gives birth in the delivery period after pregnancy, the newborn piglet is very fragile, so it is necessary to provide the piglet with a suitable temperature at this time, and then let the piglet eat breast milk at the first time. At this time, breast milk is also the best feed for piglets. The newborn pig is very weak when it is born. At this time, it can't be fed with feed, but only breast milk. special

Some piglets may appear weak after delivery. At this time, let the piglets suck the sow's front nipple to get more breast milk. Only in this way can the nutritional follow-up measures of piglets be ensured. We can change nipples according to the pig's physique. In the later stage, according to the piglet's physique, it is helpful for nest rearing and weaning. Newborn cubs should cut their teeth in time and not be treated in time in the later period to prevent slow growth.

In the later stage, in order to make the piglets grow rapidly and achieve the effect of fat pigs, it is necessary to wean the piglets in time. So, how long should we wean the piglets? In the past, it was generally enough to wean for 2 months, but because of this long weaning, the pregnancy rate of sows will decrease, and then the fertilization rate will also decrease. Now with the development of aquaculture and the improvement of technology, the weaning time of piglets is also advanced, and the weaning time of piglets in general farms is also the best weaning time of 2 1 ~ 28 days!
