Most cattle judging occurs in show rings at agricultural shows and livestock shows. [1] Judgments on cattle are ultimately based on which animal is worth the most profit. [2] [page needed] There are many fine points to cattle judging. In a beef animal, for example, it is desirable to have a large animal with muscle development. [2] [page needed]
County agricultural fairs in the United States began holding livestock judging contests for members of the 4-H, a club run by state agricultural extensions for children of farm families, in the early 1900s. Showmanship, in which the child was judged for ability to display "an animal to its greatest advantage" [3] was a component of livestock ...
Mouthing a two tooth grass-fed Murray Grey heifer prior to sale. The age of cattle is determined chiefly by examination of the teeth, and less perfectly by the horn rings or the length of the tail brush; due to bang-tailing, which is the act of cutting the long hairs at the tip of the tail short to identify the animal after management practices, the last method is the least reliable.
The concept of an animal unit (AU) has traditionally been used in North America to facilitate planning, analysis and administration of forage use by grazing livestock, but the term has also had other applications (in relation to odor control regulation, feedlot size, manure management, etc.). The term has been variously defined by regulation in ...
When it comes to sustainable livestock production and agriculture, measurement is the first -- and sometimes most elusive -- step in the process of turning our food system from a carbon emitter ...
Range Condition Scoring was developed as a way to quantify biodiversity in a given rangeland system. This practice is widely used in the Sand Hills region of Nebraska, as well as the tallgrass prairie regions, as evidenced by the authoritative book on the subject, "Range Judging Handbook and Contest Guide for Nebraska."
The United States grades feeder cattle that have not reached an age of 36 months on three factors: frame size, thickness, and thriftiness. [7]Frame size evaluates feeder cattle' height and body length as determined by their skeletal size in relation with their age; frame size affects the animals' mature size and weight gain composition as they are fed into fed cattle.
The development of quantitative methods for livestock production includes mathematical modelling based in plant-herbivore or predator-prey models to forecast and optimise meat production. An example is the Predator-Prey Grassland Livestock Model (PPGL) [7] to address the dynamics of the combined grass-animals system as a predator-prey dynamical ...
