When working with two or three groups it is easier as the caretaker can feed the low costing forage to the low group and the high quality forage to the higher group to increase the overall health and performance of the cows. For dry cows this system can minimize metabolic and nutritional disorders in calving and the post-partpartum period.
Charbray calves are born around half the size of a Brahman at a low birth weight reducing risk of calving problems but have a rapid growth rate from high feed-converting ability. Females reach maturity at around 14-17months and calve at age two, achieving high calving rates and milk production. [5]
Although different schemes have similar aims, they vary in complexity and detail. For example, some schemes give no value to a young calf, but an additional value to a cow together with her calf at foot. Some give values to different-sized animals of the same species, or different values to the same species in different regions.
A pasture wedge graph or feed wedge is a farm management tool used by dairy farmers for the purposes of managing pasture. [1] [2] [3] It takes the form of a bar graph, [4] that shows the amount of feed available in a pasture over time, and is therefore shaped as a declining wedge.

Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of outputs to inputs. [2] FCR is widely used in hog and poultry production, while FE is used more commonly with cattle. [2]
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.
A vaginal prolapse appears as a small pink or red ball of tissue ranging in size from grapefruit to soccer ball. It emerges before calving, whereas a uterine prolapse takes place after calving. [5] Vaginal prolapse occurs when there is an increase in pressure in the abdominal cavity during the late stages of parturition. [2]
