My question is methodology. Are the litter sizes quoted for live births? What is the three week survival rate for these litters? What is the average weight of the live birth piglets? My experience with many years with some of these breeds makes me question the order. Landrace is known for large litters in the15-16 piglet range. Hamps, Durocs and Chester Whites performed equally in pigs per litter in our farming operation. Some of these breeds are good mothers, but a horror for the farmers to work with because they are so protective of their litters. Yorkshire sows fall in that category. Chester Whites and Berkshires always seemed easy to handle when they had litters. In small farm operations, it isn't just the litter size that is important. It is how many piglets survive to three weeks of age. Small piglets have a hard time competing for a nipple and die off pretty quickly. If you don't have small litters available to transplant the runts to, they are lost. Our breeding program was to breed for 10-11 live births looking for heavy at birth litter weights. Normally we would wean 10 of those 11 live pigs, trying to keep litter losses to one pig per litter.
litter size is the birth number, not the survival rate. I agree that if the sow had produced 20 piglets the survival rate is very low, perhaps 50 - 70 % as the live weight is also low. I have been on the farm for many years too. thanks for your question
First of all thank you for giving this information. Sir, the "Poland China"breed is it suitable in Andhra Pradesh state (south India state) or not.? Please give me reply sir.
Is Andra a humid area? They are popular in Brazil and Argentina, with a humid climate. They need space not actually perform well in a congested farm i guess.
Chinese pig breed:Taihu pig, is the largest litters pig breed(No.1)，Taihu pig average gives birth to 16土piglets.most are15-22 piglets.It's the Mama the polandchina and camborough. PolandChina just borrowed the gene from Taihu,but your date is totally wrong, because it's a low litter pig breed. The camborough borrowed gene from Taihu,too(like Changtai,Sutai).yes,they are the main pig mamas in Chinese pig farms.
only better breed from list looking at meat and piglets production. I prefer the these ones camborough, Duroc, land race, Yorkshire and large whites breeds respective.
