FEBRUARY 11– 2 p.m. Cattle Feeding Program The Garfield County Extension Office is hosting John Paterson, MSU Extension Beef Specialist and Richard Waterman, Research Scientist in Nutrition at Fort Keogh Research Station on February 11 at 2 pm at the Hilltop Café. John Paterson, MSU Extension Beef Specialist will present his program entitled: “Will the hay in my stack meet my cows’ requirements?” John will focus his presentation on the benefits of balancing a ration. When to balance a ration, what nutrients will most commonly be lacking when feeding cows or calves and some alternatives for economically supplying those nutrients will be discussed. John will bring his wealth of experience in finding a lower cost way to adequately get your cows through the winter. Richard Waterman, Research Scientist in Nutrition at Fort Keogh Research Station in Miles City will present the program entitled: Protein Requirements by Season for Cattle Richard’s primary research areas are protein supplementation for cattle and the role of livestock in noxious weed control. This will be a very informative meeting with plenty of opportunity to discuss feeding rations and options with Extension professionals.

The weather of 2004 has proven to be the exception rather than the rule as compared to the past few years. Plenty of snow and cold temperatures have increased the amount of feed many people are providing to their cows. While the cost of feed per day increases, full feed allows for some alternatives to reduce feed expenses. The nutritional demands of cattle have increased due to the cold and snowy conditions and the cows have to rely on the rancher for all their feed requirements. Taking care of the cattle now will provide positive returns in the spring’s calf crop and in rebreeding performance this summer. Cattle should be fed to maintain a body condition (BCS) score of 5. (Cow has generally good appearance. Upon palpation, fat cover over ribs feels spongy and areas on either side of tail-head now have palpable fat cover). Research has shown that mature beef cows calving with a BCS of 5 will have maximum reproductive performance the following breeding season. Additionally, optimum condition scores on the cow at calving will maintain or slightly increase calf birth weights, but reduce calving difficulties. When preparing feed rations for cattle a good rule of thumb to remember is cows will consume approximately 2.0% of their weight in dry matter per day. For a 1200-pound cow that works out to 24 pounds of dry matter per day. At 32 degrees the requirement increases to 27 pounds of dry matter and at –5˚ F. a cow will need 30.5 pounds of dry matter. Meeting dry matter intake requirements is important during the cold weather because it is the process of rumination that provides body heat to the cow. A good rule to follow is to increase feed by 10 to 15 % when temperatures drop below 0˚ F. Dry matter is not the amount of feed provided to the cows; it is the weight of dry feed without the water included. To calculate the dry matter of a feed, the percentage of water must be deducted. For example, a 1000-pound bale measured at 90% dry matter includes 10% water; therefore the bale contains 900 pounds of dry matter. If a cow were to eat 30 pounds of dry matter from a bale that is 90% dry matter she would eat 33 pounds of hay. The 33 pounds of hay refers to the as-fed weight, which includes the weight of the water. In addition to the dry matter requirements, cattle have an energy requirement that also increases as temperatures decrease. Total digestible nutrients (TDN) are a common value used to determine the amount of energy in a feed. A 1200-pound cow in the 7th month of pregnancy has a TDN requirement of 12.4 pounds per day at 32˚. When the temperature drops to –5˚, the TDN requirement increases to 13.2 pounds. How do you know if a cow is receiving an adequate amount of TDN? The best method is to have the hay tested. The test results express the amount of TDN as a percentage. If a forage analysis states a feed TDN value is 62% and 30 pounds are fed, then the cow is receiving 18.6 pounds of TDN (30 X .62 = 18.6). The only requirement that does not change with a decrease in the temperature is crude protein (CP). Protein requirements remain at 1.75 pounds per day for a 1200-pound cow in the 7th month of pregnancy. The same technique as used to determine TDN can be used to determine if a cow is receiving adequate CP. Hay with a measured CP of 12 % fed at 30 pounds means that cow is consuming 3.6 pounds of CP (30 x .12 = 3.6). As important as it is to not underfeed cows prior to calving, overfeeding also has its drawbacks. Elevated protein levels have been shown to have negative effects on rebreeding performance due to increased blood ammonia levels. The daily cost of feed needs to be considered when balancing a ration to meet the cows nutritional requirements. In the example above, while the dry matter requirements are being met the cows are receiving excess CP and TDN. Hay that tests at 62% TDN and 12 % CP is considered very good and is not needed as a full ration for cows. To reduce the cost of the feed, straw or low quality hay can be substituted for a portion of the ration. Substituting low quality hay or straw should decrease the feed bill while still meeting the DM, TDN and CP requirements of the cattle. For more information or assistance figuring winter feed rations call the Extension Office at 557-2770. MSU Beef Specialist John Paterson will be in Jordan addressing feeding issues on February 11th. John’s program, “Will the hay in my stack meet my cows’ requirements?” will cover these and other feeding topics in more depth. Garfield County Extension Office 557-2770. Mad Cow Disease by Eric Miller-County AgentIt’s been difficult to read the papers or news magazines or even watch the evening news lately without seeing something on BSE or Mad Cow Disease. Details of exactly what the disease entails is at best sketchy, so I’ve put together some background information and am sharing it here. Bovine spongiform encephalopathy (BSE), widely known as “mad cow disease,” is a chronic degenerative disease affecting the central nervous system of cattle. The disease was first diagnosed in 1986 in Great Britain. Between November 1986 and July 2001, more than 178,000 head of cattle in over 35,000 herds were diagnosed with BSE in Great Britain. The epidemic peaked in January 1993 at approximately 1000 new cases reported per week. Agriculture officials in Great Britain have taken a series of actions to eliminate BSE including making it a reportable disease, prohibiting the inclusion of mammalian meat-and-bone meal in feed for all food-producing animals more than 30 months of age in the animal and human food chains, and destroying all animals showing signs of BSE and other potentially exposed animals at high risk of developing the disease. As a result of these actions, most notably the imposition of feed bans, the rate of newly reported cases of BSE has decreased and continues a downward trend. BSE has substantially damaged the livestock industry in the United Kingdom and quite recently in Canada as well. The disease has also been confirmed in native-born cattle in Belgium, the Czech Republic, Denmark, France, Germany, Greece, Italy, Ireland, Liechtenstein, Luxembourg, the Netherlands, Northern Ireland, Portugal, Spain, and Switzerland. The exact cause of BSE is not known, but is thought to be a prion (also sometimes referred to as a “slow virus” or virion). Prions are not bacteria or virus, but are very small proteins. Other theories on the nature of the causative agent are that it is a virus with unusual characteristics or that it is a virino-an “incomplete” virus composed of nucleic acid protected by host proteins. Whatever the causative agent, it is able to withstand many disinfectants and heat treatments that would destroy most bacteria and viruses. Similar causative agents are believed to be involved in several other diseases of animals, including scrapie in sheep and chronic wasting disease of deer and elk. Cattle affected by BSE experience progressive degeneration of the nervous system. Affected animals may display nervousness or aggression, abnormal posture, difficulty in coordination and rising, decreased milk production, or loss of body weight despite continued appetite. Affected cattle will die. There is neither any treatment nor a vaccine to prevent the disease. The incubation period (the time from when an animal becomes infected until it first shows disease signs) is from 2 to 8 years. Following the onset of clinical signs, the animal’s condition deteriorates until it either dies or is destroyed. This process usually takes from 2 weeks to 6 months. Most cases in Great Britain occurred in dairy cows between 3 and 6 years of age. Currently, these is no test to detect the disease in a live animal; veterinary pathologists confirm BSE by postmortem microscopic examination of brain tissue or by the detection of the abnormal form of the prion protein. BSE is so named because of the spongy appearance of the brain tissue of infected cattle when sections are examined under a microscope.
