As of 2015 farm-raised Atlantic salmon had a commodified feed supply with four main suppliers, and an FCR of around 1. [31] Tilapia is about 1.5, [32] and as of 2013 farmed catfish had a FCR of about 1. [8] It is possible for fish to have an FCR below 1 despite obvious energy losses in feed-to-meat conversion.
The principle of minimum energy is essentially a restatement of the second law of thermodynamics. It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at equilibrium. External parameters generally means the volume, but may include other parameters which ...
More recently, it has been used on whitetail, mule deer, pronghorn, caribou, elk, moose, and black bear. [20] It is commonly said that in the U.S. and Canada more deer have been killed with the .30-30 than with any other cartridge, and perhaps this was true for a time in the U.S.
The efficiency of conversion of ingested food to unit of body substance (ECI, also termed "growth efficiency") is an index measure of food fuel efficiency in animals. [1] ...
In fisheries, carrying capacity is used in the formulae to calculate sustainable yields for fisheries management. [35] The maximum sustainable yield (MSY) is defined as "the highest average catch that can be continuously taken from an exploited population (=stock) under average environmental conditions".
A graphic shows detections of chronic wasting disease in wild and captive deer in Wisconsin. The data spans late 2001 to early 2023.
Greater mouse-deer at the Smithsonian National Zoological Park, Washington, DC. The greater mouse-deer is an even-toed ungulate. Although very small for an ungulate, the greater mouse-deer is one of the largest members of its genus. It is rivalled in size by Williamson's mouse-deer. It weighs 5 to 8 kg (11 to 18 lb).
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 .
