Feeder cattle or store cattle are young cattle soon to be either backgrounded or sent to fattening, most especially those intended to be sold to someone else for finishing before butchering. In some regions, a distinction between stockers and feeders (by those names) is the distinction of backgrounding versus immediate sale to a finisher.
This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically shorter than placental.
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.

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 units. [4] Estimation based on metabolic body size.
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.
Female cattle, also referred to as "heifers" in agriculture, will gradually enter standing estrus, or "standing heat," starting at puberty between 9 and 15 months of age. The cow estrous cycle typically lasts 21 days. [5] Standing estrus is a visual cue which signifies sexual receptivity for mounting by male cattle.
Polled strains have been developed of many cattle breeds which were originally horned. This has usually been done by crossing with naturally polled breeds, most commonly Angus and Galloway cattle. For example, polled Jersey cattle originated in Ohio sometime prior to 1895. Two strains were developed, the first to appear being founded by crosses ...
