Beef cattle must be administered with supplemental biotin in order to enhance their milk production and increase their resistance against various hoof disorders. Preferably, cows must be fed daily with at least 20 mg of biotin through the lactation period, so as to ensure that demand is not exceeded by biological supply. Biotin is actually a sulfur-containing, water soluble vitamin that induces the synthesis of fatty acid, amino acids and glucose.

RECENTLY reported research has demonstrated the added discovery power microbiome and '-omics' studies have provided to livestock sciences. Results from these assorted trials may provide additional insights into the ruminal [...]

The purpose of this article is to review the current data and the relevant implications concerning the concept of 'accelerated calf growth.' This is a much-maligned term and often conjures [...]

A summarization of the findings of a report on Escherichia coli O157:H7 generated by the US Dept. of Agriculture reveals that the origins of the bacteria are difficult to identify and that prediction of critical control points is impossible. E. coli O157:H7 received notoriety in 1992 during an outbreak in Washington, which received national coverage, resulting in the hospitalization of 600 people and the death of four children.

DAIRY farms with higher-producing cows create smaller carbon footprints and are more profitable, a win-win situation for everyone, including the cows, according to Victor E. Cabrera, a University of Wisconsin-Madison [...]

A RECENT study by University of Montana faculty and graduate students found that wolf predation of cattle contributes to lower weight gain in calves on western Montana ranches. This leads [...]

BY selectively breeding not only cows but also their rumen bacteria, researchers in Denmark intend to reduce the release of methane while also increasing the effectiveness of the cow's milk [...]

BEEF producers shouldn't overlook proper mineral intake as part of an overall feeding plan, according to Purdue Extension specialist Ron Lemenager. Lemenager, a professor of animal sciences at Purdue, said [...]

AT the University of Kentucky Coldstream Dairy Research Farm, the staff, students and faculty have been putting a lot of effort into making the milking cows more comfortable by using [...]

DROUGHT-ravaged pastures and tight hay supplies in the Southwest mean cattle producers must take extra care this winter to balance the right amount of forage and supplement for their breeding [...]

THE U.S. Department of Agriculture's Food Safety & Inspection Service (FSIS) will take several formal steps by next March to prevent residues in beef following an audit by USDA's Inspector [...]

KANSAS State University diagnosticians are helping the cattle industry save millions of dollars each year by developing faster and more accurate ways to detect Escherichia coli. Lance Noll, master's degree [...]

RESEARCHERS from Aarhus University in Denmark have discovered that a hitherto overlooked group of microorganisms in the rumen plays a significant part in the emission of methane from cattle. When [...]

UNIVERSITY of Illinois research has demonstrated that swine producers can feed dried distillers grain with solubles (DDGS) to pigs without concern for sulfur content. 'When you buy DDGS, you don't [...]

A DUST storm reminiscent of the 'dirty thirties' hit the city of Lubbock, Texas, in mid-October. The city is surrounded by cattle feedlots and crop production, and without soil conservation [...]

ADVERSE summer feeding conditions slowed performance of cattle finished in July, which had reduced daily gains and higher feed conversions and costs. Feedyard managers reported that high temperatures, winds, dust [...]

IF a cow has never been on pasture, it may take her a few days to learn how to graze, a University of Wisconsin-Madison study suggests. Whether or not a [...]

AFTER falling for six straight weeks, the beef cutouts finally increased last week, lending some support to the cattle markets as retailers tweaked beef inventories for the Fourth of July [...]

HIGH feed costs in recent months have made it attractive to 'grow' cattle to heavier weights and feed them fewer days than usual, but there are factors to consider, a [...]

AT the recent dairy science meetings in San Antonio, Texas, there were at least six research papers that dealt with ration particle size. These studies typically evaluated physically effective fiber [...]

Going wireless: Utah State University's College of Agriculture announced that it has entered into an agreement with TekVet LLC to use its wireless TekVet System in some ongoing research efforts [...]

BROOKINGS, S.D. -- Dairy producers are looking for means to increase feed efficiency, and improvements in feed efficiency can positively affect herd profitability even when changes in production or feed [...]

High environmental temperatures and stocking density are two reasons for reduced performance of late-finishing pigs. Previous reports have shown that the digestion of dietary protein increases animal heat production, whereas [...]

Gastrointestinal parasites are a major cause of economic loss in ruminants throughout the world, and Ostertagia ostertagi (brown stomach worm) is a major contributor to the loss. According to researchers [...]

News about the successful cloning of a sheep by scientists in Scotland renewed interest in the cloning of cattle. Scientists at the University of Arkansas are finding ways by which cattle can be cloned with embryos as well as with the DNA single cell method that was used in Scotland. One problem being encountered in cattle cloning is the low survival rate of cloned calves and their surrogate mothers. Cloned calves, which usually weigh 150-200 lb. at birth, are much heavier than calves produced by the usual breeding methods.

Cattle growth due to dietary roughage was investigated to determine whether feed intake and growth is influenced energy dilution. Cattle were fed vary levels of roughage but dietary energy levels were kept constant through the addition of fat. The results showed that dietary roughage had a direct effect on feed intake and growth. Moreover, the effects of dietary roughage level on feed intake was not solely the result of the dilution of energy density.

An alliance between cattle producers, Iowa State University and animal health corporations has shown that early control of calf diets yields beef which is more tender and of more consistent quality. The research, conducted from Nov 1992 to Jul 1993, was made possible by cooperation and data-sharing between participant groups and companies. Among the other significant results of the cooperative research was the development of various formula which allow the the measurement of marbling and tenderness.
