For example, using UK government Livestock Units (LUs) from the 2003 scheme [1] a particular 10 ha (25-acre) pasture field might be able to support 15 adult cattle or 25 horses or 100 sheep: in that scheme each of these would be regarded as being 15 LUs, or 1.5 LUs per hectare (about 0.6 LUs per acre).
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, some animal unit calculations used in Texas assume that daily forage dry matter consumption by a 90-pound nanny Spanish goat is 4.5 percent of body weight. Thus the nanny:cow ratio of daily dry matter consumption is estimated at 4.5:26, or about 0.16. This yields the estimate that such a nanny is equivalent to about 0.16 animal ...

Calcium and phosphorus are needed in a specific ratio of between 1:1 and 2:1. Adult horses can tolerate up to a 5:1 ratio, foals no more than 3:1. A total ration with a higher ratio of phosphorus than calcium is to be avoided. [22] Over time, imbalance will ultimately lead to a number of possible bone-related problems such as osteoporosis. [26]
[18] [1] The horse's pulling power is limited, but still considerable in relation to its size and weight. [19] These horses are also used to work cattle and guard sheep herds. [8] They are also slaughtered for their meat, [4] [8] a purpose that mainly concerns the massive type of the breed, [10] as the meat yield of Adais is generally low. [11]
