What is the feed efficiency of swine?

Feed efficiency in swine refers to the ratio of weight gain to feed intake, typically expressed as the amount of feed required to produce a kilogram of weight gain. This measure is crucial for assessing the productivity and profitability of swine production, as improved feed efficiency can lead to lower feed costs and enhanced growth rates. Factors influencing feed efficiency include genetics, diet composition, health, and management practices. Generally, a lower feed conversion ratio indicates better feed efficiency.
