YW EPD is an estimate of post-weaning growth that is measured in pounds.

Herefords are normally docile and fast-growing cattle with good beef quality. Table 5Effect of pre-calving ration on birth weight and dystocia in 2-year-old cows, Table 6Two energy levels of pre-calving rations for 2-year-old cows. When selecting a bull to use on small British breed heifers, it is generally recommended that they not be mated to large, exotic-breed bulls, but rather to British breed bulls with low birth weights.

Average live body weight of the mature cows is around 800 kg. Herefords were the first English cattle to be recognised as a true breed. The distinctive white color face tends to dominate in crosses with all other breeds and may have been a feature in establishing the breeds popularity. Mature males may weigh up to 1,800 pounds, while mature females may weigh around 1,200 pounds. The trait was developed after years of cow weight data collection and the EPD relates directly to the maintenance requirements of a cow herd. For example, if sire A has a YW EPD of 100 and sire B has a YW EPD of 70, then you would expect on average if comparably mated, sire As calves would weigh 30 lb. (55) 25 Open Brangus heifers that will average 700 lbs. Depending on body size, stage of pregnancy, and climatic conditions, weaned heifer calves require 8 to 12 pounds TDN daily; pregnant 2-year-old heifers, 9 to 13 pounds TDN; and mature pregnant cows, 8 to 12 pounds TDN. There is a slightly positive weight on Weaning Weight, Mature Cow Weight and Milk which accounts for enough growth but ensures females do not increase inputs. Table 1Effect of dam's age on calving difficulty. The average daily milk yield of 6.16 kg was affected by the cow breed. Required fields are marked *. Researchers have demonstrated since that the influence of gestation length and the sex of the calf on dystocia are generally not direct, but indirect, through their effect on increasing calf size. The American Hereford Association is a not-for-profit organization. Oversized teats are difficult for newborn calves to nurse, and the calf may not receive adequate colostrum. Purchase Location. Table 8Breed standard birth weights used in performance testing programs.

If daughters of sires A and B are raised and managed in the same environment, you would expect half a score better udder suspension in daughters of sire A, compared to sire B. Since the base can be the year when the breed's EPD program started (over 40 years ago in some breeds) many breed averages are now markedly different from zero for some traits, especially weaning and yearling weight. If daughters of sires A and B are raised and managed in the same environment, you would expect half a score smaller teat size in daughters of sire A, compared to sire B.

As birth weight increases, the percent of assisted births increases by 0.7 to 2.0 percent per pound of birth weight. In summary: From a genetic standpoint, most of the emphasis has been placed on birth weight because research has shown it is the single most important factor associated with calving difficulty, especially in 2-year-old cows where a 1-pound increase in birth weight results in a 2 percent increase in dystocia. They are adequate in length of leg, large in size, trim and smooth.

Ability to do well on a wide range of pastoral conditions and to assimilate roughage, coupled with its excellent fertility, foraging ability and docility, account for its success. Hereford breed cows calve easily and often produce calves beyond 15 years of age. Lactation and weaning weight relationships were studied in 37 cows grazing Southern Utah irrigated pastures during the summer of 1979. These data illustrate that a dam's age has a profound effect on the incidence of dystocia. Table 1 summarizes calving data from MARC and Colorado State University (CSU) relating age of dam to calving difficulty. The Baldy Maternal Index is a maternally focused index that is based on a production system that uses Hereford x Angus cross cows. window.onscroll = function () {
