Putting on Pounds: Consider Creep Feed07 October 2014
While normally not a big fan of creep feeding, a Kentucky beef expert sees this year as an opportunity to feed before weaning.
Common problems of creep feeding calves are excessively conditioning replacements, inducing acidosis and over-fleshy feeders, but with proper management it should work, especially this winter.
Dr Jeff Lehmkuhler, University of Kentucky, writes that feed costs are low and calf prices are high, meaning increased pounds at weaning can mean more profit.
This is a year that proper creep management should allow for a nice return if things stay near the range they are currently, writes Dr Lehmkuhler.
In general, creep feeding should be provided for at least the last 60-days before weaning. Now is the time we should be considering to creep those calves to be weaned in November.
Creep feed utilization is optimized at lower rates of supplementation. Partial feed conversions tend to be better when supplement rates are near the 0.5-0.75 per cent of body weight on a dry matter basis while intakes in the 1.5 per cent of body weight range are less efficient.
Technologies that limit intake of creep can improve feed conversion. The cost of this technology must be considered to ensure that an acceptable profit margin exists. Salt has long been used as an intake limiter, but it is corrosive to metal and over time will rust out feeders.
However, poly-lined feeders or the use of poly-mineral feeders can be utilized to supply creep overcoming this issue. New feed technologies are also effective in limiting intake and can be implemented in creep mixtures to control intakes to improve efficiency of gains.
Creep feeds are generally higher in crude protein to overcome protein limitations in the forage being consumed. Young calves are in a lean phase of growth and supplementing marginal forage can improve calf performance. Often creep feeds will be at least 14 per cent crude protein with some approaching 25 per cent for lower targeted intakes.

The protein level should be a function of the expected intake while balancing the protein supply from milk and forage to the calves needs. With ample forage regrowth this fall in the upper Southeast, energy supplementation is needed more so than protein for many operations. Therefore, a 14-18 per cent crude protein range would be acceptable in creep feeds to compliment available pasture forages.
With the availability of low-starch coproduct feeds, the risk of acidosis is much less when feeding these co-products compared to grain-based, high starch creep supplements. However, a mixture of grains and coproducts can be used. Frankly, there is not a single creep feed mixture that is the best for every situation.
The composition of the forage, predicted or desired creep supplement intake, and the requirement of the calves needs to be factored in when designing a creep supplement. Also, don't overlook the possibility of creep grazing as it can be a cost effective strategy to add some inexpensive gains.
Below are a few basic considerations when putting together a creep supplement and managing the feeder.
- Keep the fines and dust to a minimum
- Consider feedstuffs and if they will lead to sorting/settling that may lead to inconsistent intakes and nutrient balance
- Avoid adding excessive moisture (i.e. liquid molasses or ear corn that is not dry) as it can lead to caking in feeders
- Avoid non-protein nitrogen sources
- Avoid excessive roughage products such as cottonseed hulls that could cause bridging and separation
- When starting to creep, limit the amount placed in feeder and monitor it frequently
- During humid weather, consider more frequent filling to avoid caking
- Keep feeders on a high traffic use pad or concrete to avoid muddy conditions around feeder
The moon and stars have aligned to present an opportunity this year to capture some added value. Contact your county extension office and / or nutritionist to obtain additional information on creep feeding your calves this fall and take advantage of this opportunity.
