A Großvieheinheit (GV or GVE) is a conversion key used to compare different farm animals on the basis of their live weight. A Großvieheinheit represents 500 kilogrammes (roughly the weight of an adult bull). In the wild it excludes small animals like amphibians and insects, but is used for game in forestry and hunting.
As of 2011 in the US, broiler chickens has an FCR of 1.6 based on body weight gain, and mature in 39 days. [25] At around the same time the FCR based on weight gain for broilers in Brazil was 1.8. [25] The global average in 2013 is around 2.0 for weight gain (live weight) and 2.8 for slaughtered meat (carcass weight). [26]
Linear estimation based on body mass or weight. This simple method is sometimes used for cattle. The number of animal units represented by one or more head of cattle may be calculated by dividing their total body mass in kg by 454 (or dividing their weight in pounds by 1000). Thus an 800-pound steer would be considered equivalent to 0.8 animal ...
For example, the dress weight for chickens and other fowl is closer to 75% of the live weight, [3] which is significantly higher than that of cattle, which can be from 50-70% depending on breed and methods used. [2] To compare, a 250-pound pig will typically have a dressed weight of 180 pounds and a retail cuts weight of 144 pounds.
Deer begin laying down their travel routes to and from the apple and oak trees, long before the fruit and nuts even ripen. On these good years, some trees produce heavy, branch-bending loads ...
Animal welfare, infection, aggression, weight, feed and water intake are variables that can be monitored by PLF. Culling can be done on the basis of reproduction values, in addition to killing out percentage, meat quality, and health. The result of incorporating this technology into large-scale farming is a potentially significantly higher ...

Consider one red drum that is 400 millimeters long and has a weight of 616 grams. Based on the reference weight-length relationship, a red drum that is 400 mm long is expected to have a weight of 655 grams. The condition index for that fish is its actual weight divided by its expected weight times one hundred percent, or (616g/655g)x100% = 94%.
