Problem Weeds in Hay and Forages for Livestock
نویسنده
چکیده
Although they may only make up a small portion of the cases presented to veterinarians, poisoning cases often require special effort. When food animals are exposed to poisonous weeds, a devastating case with large morbidity and mortality may ensue. The concern is for the herd and economics as much as treatment of the individual animal. In addition, producers and veterinarians must address food safety concerns and handle additional emotion, publicity, and medicolegal issues. Livestock poisoning associated with the ingestion of weeds in hay and forages can cause sudden death as seen with oleander or nitrate accumulating plants or a chronic disease as observed with the ingestion of pyrrolizidine alkaloid containing plants. Other problems associated with alfalfa include photosens itization and mechanical injury.

Poisonous Plants That Contaminate Hay and Forages in the Western United States
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...

In this experiment eight 1,600 mL dual-flow continuous culture fermenters were used to measure the fermentation pattern of cultivable and pasture forages in camel. Two adult camels were used as rumen inocula donors. Fermenters were fed with 120 g of DM/d in 3 equal portions at 08:00, 16:00, and 24:00 h. The trial contained two treatments of four replicate each in a completely randomized design....

متن کاملToxic Weeds in Hay and the Effects on Livestock
Eliminating toxins from the hay begins in the field. However, toxic weeds frequently end up in hay and forage and pose a serious risk to livestock. The effects of poisonous plants on animals depend on the amount ingested and the individual weed present in hay. Many indications for poisoning exist. Obvious cases involve sudden onset of disease in a number of animals. Finding of common feed or en...
متن کاملGreat Basin Cattle Nutrition Research Programs: Strategies to Improve Nitrogen Utilization in Alfalfa Hay
The majority of ruminant livestock production occurs in temperate grasslands where animals are allowed to graze or are fed harvested forages (i.e., hays or silages). As a result, forages comprise 50 to 90% of total feed consumed by ruminants during their production cycle (Reid and Jung, 1982). In the U.S., beef cattle production is often viewed as an intensive enterprise because of finishing ca...
