What is the average feed ratio for sheep?

In livestock operations (including sheep), efficiency of converting feed into muscle mass is critical for success of the farm. The feed to gain ratio is a unitless number that expresses how well an animal converts feed into mass. For example. If an animal has an average daily gain of 500g and consumes 600g of feed during this time, the feed to gain ratio (F:G) would be: 600g/500g = 1.2 This can be interpreted as the sheep needing 1.2 lbs (or kg, etc) of feed in order to gain 1 lb (or kg, etc) of weight. The lower the F:G ratio, the more efficient the pig (or animal) is at converting feed into mass. Typical F:G ratiOS for pigs range between 0.9 and 1.5, depending on life stage. A ratio above 1.5 typically indicates a poor producing pig. Depending on the institution, a ratio of gain to feed may be more often utilized. This too expresses feed efficiency, but as an inverse of the previous ratio. So the same pig who has an average daily gain of 600g and consumes 500g during that time period would have a G:F of: 500g/600g = 0.83 This is interpreted as the pig gaining 0.83 lb (or kg, etc) per 1 lb (or kg, etc). When using G:F to express efficiency, a higher number is more desirable.
