The traditional means of tracking animal location in a field is by visual observation. Not only is this method labor intensive, it is also prone to error as the observer can alter cattle movement, observation periods are often too short to obtain confidence in general daily behavior patterns, and observer fatigue becomes an issue. In the 1990s, the University of Kentucky began using GPS collars on cattle to track their position with the goal of incorporating this information into cattle management practices. One of the key unanswered questions regarding the GPS collars is the accuracy of the position data recorded …

Compositions And Methods For Enhancing Fiber Digestion, Juan Tricárico, Karl A. Dawson
Animal and Food Sciences Faculty Patents
Methods and enzyme supplements for enhancing fiber digestion in mammals and birds are described. The supplement comprises an effective amount of acetyl esterase, formulated for feeding to animals consuming significant percentages of forages in the diet. The compositions of this invention improve dry matter and neutral detergent fiber disappearance rates, and are useful dietary supplements for improving fiber digestion. The compositions of this invention may be utilized alone or in combination with known exogenous fibrolytic enzyme supplement to improve fiber digestion in mammals and birds. The acetyl esterase advantageously used in the compositions and methods of the present invention is …

Aspergillus niger is being used commercially for phytase production utilizing solid-state cultivation; however, no studies have been published that investigated the optimal environmental temperature and initial substrate water content to maximize fungal growth and/or phytase production. Solid-state cultivations of Aspergillus niger on wheat bran and soybean meal were conducted at three temperatures (25°C, 30°C, and 35°C) and three initial moisture contents (50%, 55%, and 60% wet basis) in a split-plot full-factorial experimental design. Fermentations were conducted for 0, 24, 48, 72, and 120 h. The containers were sampled destructively and assayed for phytase activity and glucosamine concentration as an estimate …

Seven Basic Elements For A Successful Native Warm Season Grass Establishment For Forage Production, Randy Seymour, John Seymour
Forage Symposium at the Kentucky Cattlemen’s Convention
First, let’s make it clear from the start, there is NO justification for plowing up all of your cool season forages and replacing them with warm season forages.
We strongly believe, and can support our belief with practical evidence, that warm season native grasses, produced in DESIGNED AMOUNTS to complement cool season forages, will make money for the beef and dairy producer.

Managing Broomsedge In Pastures, Monroe Rasnake
Forage Symposium at the Kentucky Cattlemen’s Convention
Broomsedge, broomgrass, sagegrass (Andropogon Virginiana) is a perennial, warm season grass native to Kentucky. It is well adapted to the soils and climate of this area. Add to this the fact that it is relatively unpalatable to livestock and it is easy to understand why it is common in Kentucky pasture fields. The question then becomes: why is it a problem in some fields and not in others?

Getting More From Forages, Garry D. Lacefield
Forage Symposium at the Kentucky Cattlemen’s Convention
In human endeavors, results are usually highly correlated with investments in terms of thought, time, effort, and a certain amount of money. In particular, the best and most profitable forage programs have had the most thought put into them. Top producers strive to continue to improve their operations by developing strategies, practices, and procedures that will result in “GETTING MORE FROM FORAGES”.
