A new method for assessing the operational value of sows

A new method for assessing the operational value of sows

The paper presents the results of a study of the lifespan, breeding use, and reproductive qualities of sows of the Large White breed of foreign origin. Based on the research results, a new mathematical model, “operating value of a sow,” was developed, and a scale for evaluating animals of the specif...
