The expected feed intake for the animal's level of production. 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 ...
[36] [37] When looking at meat only, ruminants consume an average of 2.8 kg of human edible feed per kg of meat produced, while monogastrics need 3.2 kg. [36] [37] Finally, when accounting for the protein content of the feed, ruminant need an average of 0.6 kg of edible plant protein to produce 1 kg of animal protein while monogastric need 2 kg.
The adjacent western provinces and northern US states are similar, so the use of corn as cattle feed has been limited at these northern latitudes. As a result, few cattle are raised on corn as a feed. The majority are raised on grass and finished on cold-tolerant grains such as barley. [61] This has become a marketing feature of the beef. [9]
Since cattle are herbivores and need roughage in their diet, silage, hay and/or haylage are all viable feed options. [14] Despite this, 3/4th of the 32 pounds (14.52 kg) of feed cattle consume each day will be corn. [15] Cattle weighing 1000 lbs. will drink an average of 41 L a day, and approximately 82 L in hot weather. [16]
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 ...
The breeding of farm animals seldom occurs spontaneously but is managed by farmers with a view to encouraging traits seen as desirable. These include hardiness, fertility, docility, mothering abilities, fast growth rates, low feed consumption per unit of growth, better body proportions, higher yields, and better fibre qualities.
In animal husbandry, a concentrated animal feeding operation (CAFO), as defined by the United States Department of Agriculture (USDA), is an intensive animal feeding operation (AFO) in which over 1,000 animal units are confined for over 45 days a year. An animal unit is the equivalent of 1,000 pounds of "live" animal weight. [1]
The best indicator of health is the body temperature of a cow, but this is not always possible when looking over many animals per day. [18] The diet of the animals and the different ingredients within the ration are controversial. Cattle in feedlots are fed grain rather than more natural forage.
