and < 50 ppb T-2. The data suggest that in piglets exposed to weaning stress and a natural infection with HPS, DON levels as low as 220 ppb can decrease performance. From day 15-20, all piglets were treated with Vital TSS (Trimethoprimum, Sufathiazolum and Sulfidimidinum). This treatment effectively controlled the HPS infection. During this trial phase no differences in performance were recorded between treatments, indicating that a reduction in stress level did allow the piglets to cope with 220 ppm of dietary DON. Mycotoxin-contaminated straw did not affect piglet performance or health. However, low levels of dietary DON led to a reduction in performance in piglets exposed to weaning and microbial stress. Mycotoxin adsorbent can help in alleviating the negative effects on performance.

Improving The Productivity Of Beef Pastures In Northwest Minnesota
Pastures are an underutilized and under-managed resource on many beef operations. Is it worthwhile to place more management emphasis on pastures? One might think that given the long winters we face in northwest Minnesota, we have to rely so heavily on conserved forages anyway that better management of pastures during the relatively short window they are useable may not be worth the effort. Howe...
متن کاملManagement Strategies for Rangeland and Introduced Pastures Oklahoma Cooperative Extension Service
Oklahoma is blessed with an abundance of excellent forage resources. Many Oklahoma producers enjoy the benefits of operating livestock production systems on both rangeland and introduced-forage pastures. However, some producers may not be aware of the need for different management strategies for the two ecosystems. Improper management generally results in decreased profitability of the livestoc...
متن کاملHeifer Production on Rangeland and Seeded Forages in the Northern Great Plains
Integrating use of seeded perennial cool-season grass pastures with native rangeland can increase available forage and provide a high plane of nutrition for grazing livestock. Our objective was to compare performance of yearling beef heifers grazing native rangeland with those grazing an integrated system that included seeded forages. Twice-replicated, 3-ha pastures seeded to either ‘Rosana’ we...
متن کاملMineral Concentrations of Cool-Season Pasture Forages in North Florida during the Winter-Spring Grazing Season: I. Macro Minerals
Concentrations of selected macro minerals (Ca, P, Na, K, and Mg) were determined from coolseason annual grass pasture forages over four consecutive late fall-winter-spring grazing seasons (2001-2005). Forage samples were taken from eight experimental pastures used in beef cattle grazing trials. Two, 2-yr experiments were conducted; animal and pasture data were reported previously (Myer and Blou...
متن کاملMineral Concentrations of Annual Cool Season Pasture Forages in North Florida during the Winter-Spring Grazing Season: II. Trace Minerals
Concentrations of selected trace minerals (Cu, Fe, Zn, Mn, Co, Se) were determined from annual cool-season grass pasture forages over four consecutive winter-spring grazing seasons (2001-2005). Twice monthly forage samples were taken from eight experimental pastures used in beef cattle grazing trials. Two, 2-yr experiments were conducted; animal and pasture data were reported previously. Each e...
متن کاملNative Warm-Season Grasses: Naturally Adapted Productive Pastures
The series of severe droughts between 2007 and 2012 resulted in substantial decreases in cattle numbers – and enterprises – in our region. Some of the impact of these droughts may have been offset if producers in the region had reliable, drought-resilient summer forages. For all of the benefits of tall fescue, it was never meant to provide our summer forage. After all, it is a coolseason grass....
