Biggest costs of bloat may be in undiagnosed cattle
Submitted by harminka
Cattle deaths due to bloat are an economic loss, but the greater cost may come during the early stages of bloat, said a Texas Agricultural Experiment Station researcher at Vernon.
“What you don’t see will be the hidden loss of depressed animal gains ranging from one-third to a little more than one pound per day over a 60-day bloat period in cattle with slight to moderate bloat,” said Dr. Bill Pinchak, Experiment Station range animal nutritionist.
Know Your Feed Terms
Ropin’ the Web
When you are talking nutrition and feeds with your feed salesperson, livestock nutritionist, veterinarian or neighbour, it is important that you both speak the same language and understand what the other person means.
You will find this list of common meanings of feed terms helpful when you are talking nutrition, reading articles, feed analysis reports or feed tags.
Acid Detergent Fibre (ADF) – the fibrous, least-digestible portion of roughage. ADF consists of the highly indigestible parts of the forage, including lignin, cellulose, silica and insoluble forms of nitrogen. Roughages high in ADF are lower in digestible energy than roughages that contain low levels of ADF. As ADF levels increase, digestible energy levels decrease.
Baxter Black: GOODBYE, JIM
by Baxter Black, DVM
A rodeo legend died last month. Jim Shoulders, 16 times world champion in bulls, broncs and all around…Unequaled in the annuals of rodeo.
I knew Jim in the same way I knew Casey Tibbs and know Harley May. As a tribal elder. They had achieved their rodeo pinnacles before I was old enough to appreciate their accomplishments. I missed their heroics but I was a recipient of their wisdom. And they had time to talk to me.
That is different than my acquaintance with Larry Mahan and Ty Murray. I followed their careers and take pleasure in their success. They reign now as chieftans, retired but still actively involved and influential…still busy.
University of Tennessee Extension Organizes a Drought Information Website
It is no secret that Tennessee is experiencing a drought and that August is on track to be the hottest on record.
Despite scattered rain and showers, home lawns have dried up, crops and pastures are very stressed, and the entire state has been declared eligible for federal agricultural disaster assistance. Areas in other states across the region are experiencing similar conditions.
To help farmers and consumers confront the situation, University of Tennessee Extension has organized information about the effects of the drought on plants and animals on a central website. Visit http://utextension.tennessee.edu/Drought2007/
Selenium – The critical performance component
By J.A. Davidson, P.Ag., PAS
The importance of selenium in the nutrition of livestock and poultry has been recognized since 1957 when it was first identified as an essential micronutrient. It was in the early 1970s that supplementation of animal diets with either sodium selenite or selenate became an accepted practice worldwide.
Selenium is a metalloid with chemical properties similar to sulphur and was first discovered in 1818 by J.J. Berzelius, in Sweden. It is estimated that worldwide, selenium has an average concentration of only 0.05 mg/kg in the soil. The amount of selenium present in soil for absorption by plants is directly related to the amount of selenium in the rock that weathered to form the soil.
Scanning Your Future
UGC technician answers commonly asked questions about collecting ultrasound data.
Brett Setter, UGC ultrasound technician
When I first became an Ultrasound Guidelines Council (UGC) ultrasound technician I wanted to have a company slogan or phrase that exemplified what it means to scan cattle. I wanted it to be short, sweet and to the point. I thought about it for a few weeks.
One day my wife and I were driving, and she came up with a simple catch phrase that captured the entire ultrasound process in three simple words — “scanning your future.”
Infectious Diseases that Affect Cattle Fertility
Nolan R. Hartwig, DVM, Iowa State University
Calving percentage, the number of calves weaned divided by the number of females exposed to bulls the previous year, is the most important production parameter that can be measured. The first priority of cow/calf health and production programs should be to emphasize reproduction.
The most common cause of reproductive failure in beef herds is failure to conceive in the first place. Failure of cows and heifers to come in estrus while exposed to bulls is the leading cause of conception failure. The most common cause of anestrus, in turn, is nutrition; specifically lack of energy intake during the early lactation period. Body condition and energy intake pre- and post-calving are critical aspects of maintaining high herd fertility. A basic health program should include condition scoring cows in late fall and feeding accordingly through the post calving period. Infectious diseases are often immediately blamed when unacceptably high numbers of open cows and heifers are encountered. Cow condition and nutrition should be the first consideration. Protein deficiency is uncommon as a cause of infertility. Minerals such as phosphorus, selenium, copper, zinc, and others should be considered, but can usually be handled when mineral and salt mixtures designed for beef cows are available in a palatable form. Toxins such as endophyte infected fescue should also be considered when infertility problems occur
