Description

technical field [0001] The invention relates to a pig feed, in particular to a health-care feed additive for farrowing sows. Background technique [0002] With the development of intensive and large-scale pig production and the improvement of management level, in order to achieve high production efficiency of sow herds, manufacturers have higher and higher requirements for the quality, variety, health status and litter rate of pig herds. By improving the management means, the pig herd can be produced at full capacity under the control of a strict production plan, thereby increasing the proportion of abnormal pig herd elimination. In these culled herds, a significant proportion of individuals were culled due to reproductive and lactation problems. Excessive sow culling rate will bring pressure to normal production, increase the production cost of gilts, and also have a negative impact on the stability of the entire pig herd production. People add a large amount of chemical ...
