In the past, many cases of laminitis have been of mysterious origin. Recent investigations in veterinary medicine, coupled with the availability of new techniques for analyzing hydrolyzable carbohydrates in forage may provide evidence to solve some of these mysteries. Fructan has been shown to be capable of inducing laminitis in clinical studies. Insulin resistance, a primary feature of Equine ...

A field study was made of the effects of a residual nematicide (phenamiphos), a fumigant (methyl bromide), and fallowing on the number of root lesion nematodes (Pratylenchus penetrans), forage yields of alfalfa, and the occurrence of Fusarium spp. in plant roots and soil. Fallowing controlled nematodes initially, but by the end of the second growing season, nematode numbers were as high as in p...

The grass pea (Lathyrus sativus) is a dual purpose forage seed legume crop. It has a good potential as winter forage legume under Saudi Arabian conditions. This study was conducted in 1993/94 and 1994/95 seasons to evaluate 15 selection lines of the Grass Pea for forage, seed yields and other growth characters. Combined analysis of data from the two years revealed significant difference between...

Three grass species, Agropyron desertorum (Agde) and Agropyron elongatum (Agel) and recently, Bromus tomentellus (Brto) are mainly used for range improvement as mixed seeding in semi-arid areas of Iran. Because there is little information about management of these grasses, this study was conducted at the Sisab Research Station in northern Iran to evaluate their responses to grazing management a...

AND INTRODUCTION In the Western United States poisonous plants are estimated to cost the animal industry more than 200 million dollars annually. The majority of these losses are attributed to livestock grazing on rangelands. Little has been done to determine the costs of livestock poisoned by contaminated feeds which are probably more frequent and costly. Grazing livestock generally avoid eatin...

Concentrated sources of dairy manure represent significant water pollution potential. The southern United States may be more vulnerable to water quality problems than some other regions because of climate, typical farm size, and cropping practices. Dairy manure can be an effective source of plant nutrients and large quantities of nutrients can be recycled through forage production, especially w...

Corn harvested for silage is an important feed crop on most Pennsylvania farms, where cropland often is limited. The crop provides livestock producers with a high-yielding, relatively consistent source of forage and the animals with a highly digestible and palatable feed. Corn silage produces more energy per acre than any other crop grown in Pennsylvania. Corn silage serves as a high-energy for...
