Beef specialists warn of bloat on wheat pasture
Varying degrees of drought across the state have caused cool-season grasses to grow a little later than usual this year, and Oklahoma State University Extension specialists have received reports of bloat in calves grazing wheat and other small grain pastures.
Growing conditions improved for these pastures, which have been grazed short this winter with regrowth that is all highly digestible leaf.
“We have also had some late winter frost events that can damage the cell walls in the new growth, releasing the cell contents for rapid availability in the rumen, said Paul Beck, OSU Extension beef cattle nutrition specialist. “These plant fractions are the most bloat provocative and can very quickly cause bloat in grazing calves.”
Death can occur rapidly from bloat, but so can relief. Calves can return to normal soon after supplements containing Bloatguard (Poloxalene 6.6%). Bloatguard is commercially available in blocks, mineral supplements and topdresses for concentrate supplements.
- Don’t wait until the bloat outbreak occurs. Have some type of block, supplement or mineral on hand that contains Bloatguard. Not all feed stores carry this item. Ranchers may have to travel to another town to find it.
- Feed calves a few days a week throughout the winter to keep them coming up to troughs so they can be easily gathered if bloat occurs.
- Mineral or supplements providing ionophore monensin decrease the incidence and severity of bloat. This will make it more manageable to identify bloat outbreaks before they cause death losses and allow time to take corrective measures.
Replacement heifers and spring breeding
- Should be 14 to 15 months of age
- Roughly at 2/3 of their mature weight
- Over 90% of heifers at this age and weight will be fertile, ready to conceive and on schedule to calve at 2 years of age
Body Condition score of cow herd
- Heifers should be at about a 6
- Cows should be at a 5 ½
- Monitoring body condition scores is as important as it’s ever been this year because of the large amount of nontraditional hays that have been fed
Deworming
Deworming can be the least expensive way for cattle to maintain or add body conditioning. Johnson recommends checking records and analyzing the cost effectiveness of deworming the herd.
