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] For hens used in egg production in the US, as of 2011 the FCR was about 2, with each hen laying about 330 eggs per year. [25]
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.
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 ...
This is combined with artificial lighting conditions to stimulate eating and growth and thus the desired body weight. In the U.S., the average feed conversion ratio (FCR) of a broiler was 1.91 kilograms of feed per kilograms of liveweight in 2011, an improvement from 4.70 in 1925. [18] Canada has a typical FCR of 1.72. [19]
By the age of one, they have reached around 65 % of their adult weight and 90 % of their adult height, which explains the often gangly appearance of foals at this age. [10] Draft foals fattened for slaughter weigh on average 59.3 % of the adult horse's live weight at 8 months, then 70.1 % at 12 months, and 90.1 % at 30 months. [2]
To calculate BMI, divide a person’s weight in kilograms by their height in meters squared. Translated into imperial, that’s a person’s weight in pounds divided by their height in inches ...
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
A carcass grade (or expected carcass grade) is used to determine selling prices for cull cows, which are estimated to comprise 20% of the beef available to consumers in the United States. [ 1 ] A Body Condition Scoring system or BCS, which is used to grade live cows and bulls, is used to determine the carcass grade. [ 1 ]
