Beef Cattle

Why they are Important to Oregon

In Oregon, cattle are raised in all 36 counties. Cattle have been raised in Oregon since 1824. In 2009, the Oregon Department of Agriculture Statistics estimated Oregon had 960,000 head of beef cattle. Cattle and calves ranked fourth among Oregon commodities in 2008; with total sales about $426.8 million. The top Oregon counties for raising cattle are Malheur, Morrow, Harney, Klamath and Lake.

History of Cattle

Laxcaux Aurochs

Not long ago cattle were used for many purposes including meat, milk, and labor. Today beef cattle are raised primarily to provide people with meat, and hundreds of useful by-products. Most cattle graze on grassland that is steep, hilly, dry or rocky and not suitable for building houses or growing crops. The main reason cattle are raised in different climates and settings all over the world is because they can thrive on low quality rangeland feed and grasses.

Cattle are descended from a wild ancestor called the aurochs. The aurochs were huge animals which originated on the subcontinent of India and then spread into China, the Middle East, and eventually northern Africa and Europe. Aurochs are one of the animals painted on the famous cave walls near Lascaux, France. People started domesticating aurochs between 8,000 and 10,000 years ago. Cattle were domesticated after sheep, goats, pigs, and dogs.

Cattle were first brought to the western hemisphere by Columbus on his second voyage to the New World in 1493. Spanish explorer Hernando Cortez took offspring of those same cattle to Mexico in 1519. In 1773, Juan Bautista de Anza brought 200 head of cattle to California to supply the early California missions.

Cattles Amazing Stomachs

Cattle are ruminants. This means they have one stomach with four separate compartments. Their digestive system allows them to digest plant material by repeatedly regurgitating it and chewing it again as cud. This digestive process allows cattle to thrive on grasses, other vegetation, and feed. A cow chews its cud for about eight hours a day. When an animal chews its cud it is a sign of health and contentment. Other ruminant animals include deer, elk, sheep, and goats.

Life Cycle

Many ranchers run cow-calf operations. They keep a herd of cows to produce calves. The cows are bred to calve in the spring or fall. Cows, like humans, are pregnant for nine months.

Calves

For the first three weeks of the calf's life they only drink their mother's milk, because their rumen is not yet fully developed. Rumen is one of the stomach chambers in ruminant animals. Humans do not have rumens. Between 3-8 weeks the calf goes through a transitional period where they start eating some hay and grass along with the milk. After eight weeks the calf's rumen should be fully functioning. The rumen will grow 25 times larger from birth to adulthood.

Tagging, Branding & Earmarks

Tagging and Branding
Ear tags and brands are ways ranchers track their cattle.

A newborn calve is commonly tagged. Each ear tag has an individual number which helps ranchers pair the mother with their young and track the calf through its lifecycle. Within the first few months, the calves will be branded. A brand is an identification mark for cattle. It can either be a hot iron brand or a freeze brand. Some operations use earmarks, as an additional way to identify their cattle. During branding all calves are vaccinated to help prevent disease. The young male calves are castrated during the first few months. After castration, they are referred to as steers.

Adulthood - Finishing

Calves are usually sold after they are weaned, at about six-eight months. After weaning, cattle are sent to feedlots for approximately 120 days where they are fed a high-energy ration of grain and hay. After this time called finishing, the cattle are sent to a harvest plant.

To keep the herd size approximately the same, ranchers save replacement heifers (females). The steers (males) will be sent to the feedlot while a few heifers are kept behind to raise and later produce calves themselves. Other heifers will go to the feedlot as well. Steers are more common in the beef industry, because they grow faster and naturally have more muscle.

The ideal breeding age for heifers is at least 14-16 months of age, depending on breed. Heifers should be about 65% of their mature weight before breeding.

Breeds

There are numerous breeds of cattle raised in the United States. Some breeds have been around for centuries, while others have been developed in the last couple of decades by mixing older breeds. Each breed is characterized by different traits suchs as size, weather tolerance, color, markings, hair length, and temperament.

There are two classifications; Bos indicus and Bos taurus. Bos taurus includes British and Continental. British breeds, also known as English breeds, are smaller in size than Continental breeds. These breeds are the foundation of the United States beef herds. Common English breeds include Angus, Red Angus, Shorthorn, and Hereford.

Continental breeds, also called Exotics, originated in Europe. They are larger in size, lean, muscular, and can tolerate hot climates. Continental breeds include Charolais, Limousin, Simmental, and Salers.

Bos indicus are humped cattle originating from South Central Asia. They are adapted to the stresses of heat, humidity, parasites, and poorly digestible forages. Bos indicus breeds are often found in the southern United States. Common bos indicus breeds are Brahman, Brangus, Beefmaster, Simbrah, and Santa Gertrudis.

Nutrition

Beef is a nutritionally rich food and an excellent source of ten essential nutrients. A three-ounce serving of lean beef contributes more than 10% of the daily recommended value of protein, zinc, vitamin B12, selenium, phosphorous, choline, niacin, vitamin B6, iron and riboflavin. Beef is among the top food sources for protein, zinc and vitamin B12. Some common types of lean beef cuts include: top sirloin steak, 95% lean ground beef, rib eye steak, T-Bone and tenderloin steak. The U.S. Department of Agriculture's Nutrient Database shows that many cuts of beef are 20% leaner than they were 15 years ago. Half of the fatty acids found in beef are monounsaturated, the same “good healthy fat” found in olive oil.

Beef By-products

Besides meat and milk, cows provide us with hundreds of important by-products. Almost the entire beef animal can be used in some way. From a typical 1,000 pound steer, slightly over 40% of the animal is used for retail beef and the remaining 60% is processed into by-products.

By-productsBeef by-products are anything made from a beef animal other than meat. You probably use more beef by-products than you think! Some edible examples include margarine, gelatin and marshmallows. Non-edible by-products include leather, soap, cosmetics, crayons and buttons. Cattle also contribute to the health industry. Here are some examples.

Bone, Horn, Hooves, and Gelatin: combs, gelatin candy (Gummy Bears), photographic film, steel ball bearings, fine bone china, pet food, and vitamin capsules/gel coatings.

Hide and Hair: insulation, paintbrushes, glue for bookmaking and band-aides, clothes, shoes, luggage, saddles, furniture, automobiles, volleyballs, basketballs, and baseball gloves.

Fats and Fatty Acids: shampoo, shaving creams, deodorants, candles, crayons, floor wax, detergents, hydraulic brake fluid, plastics, insecticides, paints, perfumes, and synthetic rubber.
