There are several variables that affect birthweight, including breed, genetics of sire and dam, length of gestation (heritable), age and size of dam, sex of calf, environmental factors, nutrition and health of the dam.

In addition to EPDs, another valuable management practice to reduce the frequency of calving difficulty is to cull heifers with small pelvic areas. A substantial amount of research has been done to quantify the relationship between pelvic area and birth weight as it relates to dystocia.

Large, heavy calves are more difficult to expel than calves of average weight for the breed, and therefore are prone to more difficulty at birth and a greater rate of stillbirths. Male calves need to be assisted at birth much more frequently than females as they are generally heavier.

Research indicates birth weight is by far the most significant contributor to calving ease. In fact, researchers found that 60% of calving difficulty (dystocia) is due to calf birth weight. and increase the percentage of calf crop.

Older bulls don’t throw bigger calves.

Salers sired cows put to the Charolais or Simmental bull are proving very successful as they calve unassisted to these breeds and have the milk and mothering ability to rear an outstanding calf that commands a premium at market.

Sixty two percent of the calves were weaned between 170 and 230 days of age and replacement heifer calves had an average weaning weight of 532 lbs while bull and steer calves had an average weaning weight of 559 lbs.

The average weaning weight per cow exposed for all cows in the study was 341 pounds. The average cumulative weaning weight per cow over her lifetime in the herd was 1,220 pounds. Angus-Brahman-Hereford three- breed rotation cows had the highest weaning weight per cow exposed at 414 pounds.

around 1.75 pounds per day

Most Black Angus cattle are medium to large, naturally polled with large muscle content. Average body weight for bulls is about 1,870 pounds, while cows weigh in at 1,200.

They will weigh in about 582 lbs.

Cow weight will greatly vary based on many factors. Angus beef cow will be about 450-550 pounds when 6 months old, while a mature heifer could weigh anywhere between 800 and 1400 pounds.

The Brangus breed was developed to the superior traits of Angus and Brahman cattle. Their genetics are stabilized at 3/8 Brahman and 5/8 Angus. Angus are known for their superior carcass qualities. Angus cows are also extremely functional females excelling in fertility and ability to be milked.

Like the camel, the Brahman stores food and water in the odd- looking hump on its back. The hump is a deposit of fat. Farmers and ranchers in the southeastern US and the Gulf States like to raise Brahman cattle because they can stand the heat, and insects don’t bother them much.

Red Brangus are a polled breed of cattle with a sleek shiny coat and pigmented skin; their ears are medium to large in size, with typical floppy skin neck rolls associated with bos indicus breeds.

Definitions of Bos taurus. domesticated bovine animals as a group regardless of sex or age. synonyms: cattle, cows, kine, oxen.

The Hereford was used to represent Bos taurus (British type) and the Brahman was used to represent Bos indicus breeds.
