Peabody will work with the selected livestock operator to implement procedures designed t:o
mitigate some of the potential for bloat and maximize the benefits to the reclaimed land;.. •
Turning the animals in early in the season will allow them to become acclimated to the
alfalfa in the stands. Maintaining the livestock in the pasture throughout the grazing
season will aid in substantial removal of the top growth of the alfalfa while depleting
root reserves. This will reduce flowering, viable seed production, and sunlight and space
competition for other species. Late season grazing, if heavy enough, can seriously
deplete root reserves, reduce vigor and may result in winter kill under certain
situations. White the entire stand nitl not be affected equally, those plants heavily
selected by the grazing animals will be continuously reduced in vigor. Because of ttre
palatability of alfalfa, it should be selected continuously resulting in the desired
reductions in vigor.
Turning animals in during mid-season will increase the risk for bloat because of maximum
alfalfa growth during this period. Operators will not be encouraged to turn-in during
this period unless they are committed to intensive management, it is determined that the
animals have been acclimated, or it appears that the primary period for bloat has passed.

bloat. However, it should be noted that death losses due to bloat cannot be completely
eliminated, even in stands that appear to have a relatively low composition of alfalfa.
Variables such as differences in bloat susceptibility ol` individual animals or condition
of animals when turned-in are difficult to control. !iome of these management methods
include proper turn-in times during the day as well as during the season, proper
conditioning of the animals prior to turn-in, frequent: monitoring of livestock during
grazing with particular emphasis on the first several days after turn-in, and use of bloat
prevention supplements using the anti-bloat ingredient Poloxalene.
Carolyn Moon, a local livestock operator in the Hayden area, has run cattle during the
1985 and 1986 grazing seasons (mid-May to late October) in prrlaw reclaimed areas at
Seneca. These stands have a fairly heavy alfalfa composition similar to the 1978-1981
reclamation. She reported no losses to bloat and was very satisfied with the overall
animal performance and gains achieved by the end of the season.
Water and salt or bloat guard supplement will be placed within the pasture to insure
maximum grazing distribution. Adjustment of salting/supplement locations will be used to
