Different breeds of sows have different milk yields. Under the same feeding conditions, the milk yield of local excellent pig breeds is generally higher than that of foreign introduced pig breeds. In addition, the number of times of the fetus is different, and the amount of lactation is not the same. The lactation of the tenth sow is generally lower than that of the sow. Later, with the increase in the number of births and to maintain a certain level, to 7-8 after the child slowly decline, fruit feeding and management is good, even after the 7-8 child will not be significantly decreased. Therefore, in order for sows to have high milking power, they should overcome no factors, create suitable conditions, give full play to the potential of lactation, and increase the survival rate of piglets.
Factors Affecting Sows' Milk Production
Sow milk production and what factors? There are many factors that affect the sow’s milk production, such as breed, age, parity, feeding conditions, and number of litters, but the total measure is the most important for feeding conditions. The level of nutrition not only affects the amount of milk, but also directly affects the quality of milk. The amount of nutrients a pig needs during lactation must ensure that the sow can produce enough milk to rely on the sow's lactation to meet its nutritional needs. In addition, the supply of nutrients not only considers the nutritional needs of the sow itself, but also the number of heads of nursery pigs. Day-to-day management has a large impact on the sow's milk yield. Random changes, feeding changes, unsafe environment, rough sows on the sow, and startling sows can all affect lactation.
