Lawsonia Prevalence Patterns Investigated

Yearly variability in exposure to a severe disease-causing bacterium of young horses appears to be different than previously thought. Despite the common belief that the incidence of equine proliferative enteropathy (EPE), a severe gastrointestinal disease of foals and long yearlings, spikes higher in some years than in others, researchers have recently fo...

New Diagnostic Assay for EPM Developed

Dan Howe, PhD, a molecular parasitologist at the University of Kentucky Gluck Equine Research Center, has developed a new assay to aid in diagnosing equine protozoal myeloencephalitis (EPM). This enzyme-linked immunosorbent assay, or ELISA, measures antibodies to the surface antigens (SAGs) SnSAG2, SnSAG3, and SnSAG4 of Sarcocystis neurona, the parasite t...

Grazing Management During Drought

Much of Kentucky has been behind on rainfall since spring began, but the drought has been exceptional in Western Kentucky with some cities 8 and 9 inches below normal rainfall totals. With some of the state's historically driest months ahead, good pasture management is critical for livestock producers, said forage extension specialists from the Univer...

Mild Winter Impacts Weed Emergence

The mild winter weather and excellent soil moisture have resulted in rapid growth of many cool-season weeds this year in Kentucky. Weed growth is currently about three to four weeks ahead of "normal" development. This means pasture managers need to scout fields now and be prepared to initiate control tactics sooner than normal. Henbit, purple de...

Horse Lysine Requirements Focus of Study

Lysine is one of the 20 amino acids essential to horses, but it often is the most deficient in their diets due to its inadequate levels in commonly-fed cereal grains. Amino acids are the building blocks of protein, which form muscle, enzymes, and hormones throughout the body. Horses can only use them if all essential amino acids are present at sufficient ...

Colic in Horses: General Review

Among the species of domestic livestock, the horse is the animal that most commonly suffers from colic. Colic is a general term indicating abdominal pain. The anatomy of the horse's digestive tract, how the tract works, and the management practices imposed by man seem to contribute to colic's occurrence. Colic might not be caused solely by disease...

Weed of the Month: Common Ragweed

Common ragweed is distributed widely across the United States and occurs in pastures and cultivated crops. Infestations in pastures are usually more of a problem during periods of drought or when overgrazing occurs. Leaves usually alternate between the upper and lower portions of the stem. Stems can be smooth or hairy and are usually branched. Mature plan...
