The regular feed conversion ratio, i.e. output fish mass divided by total feed mass. The conversion ratio only taking into account the fish-based component of fish feed, called the FIFO ratio (or Fish In – Fish Out ratio). FIFO is fish in (the mass of harvested fish used to feed farmed fish) divided by fish out (mass of the resulting farmed ...
A feed ratio is a measure of profitability of animal husbandry, expressed as the ratio between the cost of food and the price of the final product. For example, in pig farming , the hog/corn ratio is the number of bushels of corn equal in value to 100 pounds of live hogs .

To calculate your operating profit margin, divide the operating income by revenue and multiply by 100: Operating Profit Margin = (Operating Income / Revenue) x 100
The residual portion between the amount of feed the animal is expected to eat, and what the animal actually eats. [2] Through the use of these two items, animals that deviate from the expected feed intake, either by eating more than or less than what's expected of them, can be identified and managed as the farmer sees fit.
[5] [6] Such a calculation reflects an assumption that feed requirement will be proportional to metabolic body size. (Metabolic body size is commonly defined as body mass, in kg, to the 0.75 power. [7]) Using this method of calculation, an 800-pound steer would be considered equivalent to 0.85 animal units.
Feedlot and intensive finishing are intensive forms of animal production. Cattle are often "finished" here, spending the last months before their slaughter gaining weight. They are fed nutritionally dense feed, also known as "concentrate" or "filler corn", in stalls, pens and feedlots at high stocking densities in enclosures. This achieves ...
