December beef cattle tips from U of A System Division of Agriculture
of
Welcome to the December issue of Beef Cattle Tips from the University of Arkansas System Division of Agriculture. Beef Cattle Tips is a monthly newsletter designed to remind you of timely production practices that could benefit your operation.
Items presented in this newsletter should be completed sometime this month, if it has not already been addressed.
General management
-Winter is a good opportunity to catch up on equipment maintenance including lubrication and fluid change of tractors, packing wheel bearings on trailering equipment and checking tires on trailers, field equipment, etc., and replacing floors in stock trailers.
-During December, some days are better spent indoors than outdoors. Now is a time to summarize herd records for the year and compare to previous year to determine the production direction of the herd. Valuable summaries include changes in 205-day adjusted weaning weights, monthly calving distributions, culling percentages, calf crop percentages, cow age and body condition and calving interval changes.
-December is a good month to summarize your financial records. Determine your cost for mineral, supplemental feed, vet medicine, fertilizer, hay, weed control, etc. Knowing your cost to maintain a cow per year is very important and will aid in marketing decisions.
-Plan next year’s budget and production plans.
-Proper free choice mineral and fresh water is just as important in the winter time as in the summer time.
-Do not use frost-damaged Johnsongrass as pasture for seven days after the first killing frost. Delay pasturing for least seven days or until the frosted material is completely dried out and brown in color. The Johnsongrass may contain prussic acid which can cause sudden death in cattle.
-Deworm cattle to prevent weight loss and inefficient use of hay and feed supplements going into the winter. For most locations in Arkansas the weather this past summer and fall were ideal for parasites and therefore cattle are probably carrying higher numbers than normal.
-Monitor cattle closely for signs of respiratory disease. The large variations in temperature in the fall can contribute to decreases in respiratory immune function which may lead to pneumonia.
-Exclude cattle from access to oak trees whenever possible. Acorns are falling and are toxic to cattle causing kidney damage and death.
Tips for Fall calving herds
-Turn bulls in with cow herd. Watch bulls behavior carefully. Be sure they are seeking cows in estrus and are able to mount and breed cows.
-Breeding fall calving heifers should be about over by the end of December. It is important for heifers to breed early in their first breeding season and it’s a good idea to breed heifers 30 days before the mature cow herd. Heifers should have had three chances to breed by the end of December.
Monitor body condition especially if December is cold and wet. Winter weather can bring an increase in TDN and dry matter intake. Additional hay and supplement maybe necessary to maintain proper body condition and performance.
Tips for Spring calving herds
-Deworm cows prior to calving
-Evaluate heifer weights - it is important heifers weigh 65% of their mature weight at breeding time. Monitoring heifer development and weight gain ensure heifers will reach their target weight.
-Some pregnant heifers may actually calve in late December. It is very important to watch pregnant heifers very carefully and assist when necessary. To learn more about calving and when and how to assist during calving read Fact Sheet 3105 .
Pasture Management
-Soil fertility management
-Fall and winter is a good time to correct imbalances in ph
-Soil fertility and ph should be monitored regularly
-ph in pasture soil drops relatively fast because of leaching of calcium carbonates and lack of soil mixing like in a cropping system with frequent tillage
-Correcting ph will take several months so it is wise to check lime requirements before next year’s growing season
-Collect at least 15 subsamples per pasture using a zig-zag course
-Mix the subsamples then submit one composite sample per pasture to the county extension office
-Use appropriate crop code
-Refer to Fact Sheet 2121 .
Weed control
-Winter annual weeds such as buttercup, thistle, and henbit are germinating now.
-Start spraying pastures where there were problems in the past.
-Late fall and winter spraying is very effective.
-For identification and control recommendations, refer to MP 522.
Grazing management Stockpiled bermudagrass
-Graze out by January 1 -Use grazing methods that avoid trampling of forage and ensure high forage utilization, such as strip grazing
-Strip grazing improves forage utilization and may double the number of grazing days compared to continuous grazing.
Stockpiled fescue
-Begin grazing
-Use grazing methods that avoid trampling of forage and ensure high forage utili
zation, such as strip grazing. - Fact Sheet 3133.
Winter annual grains/ryegrass
small -Begin grazing once canopy reaches height of 8 inches.
-Use grazing methods that avoid trampling and ensure high forage utilization, such as rotational grazing or limit-grazing.
-Under limit-grazing, cows are routinely pastured on dormant pasture or fed hay in a dry-lot, but are allowed to eat their fill from a limited-access winter annual pasture several times per week.
-Research has demonstrated, limit-grazing of beef cows and calves on a mixture of wheat/rye/ryegrass (planted at 0.2 acre of per head) for two days per week produced the same cow, calf, and rebreeding performance as cows fed unlimited hay plus a supplement.
-Limit-grazed cows also consumed 30 percent less hay during the winter feeding period.
-Fact Sheet FSA3064
Brassica (turnips, turnip hybrid, rape)
- Livestock must acquire taste.
-Use grazing methods that avoid trampling of forage and ensure high forage utilization, such as rotational grazing or limit-grazing. -Graze out by January 1. -Fact Sheet FSA61 -Hay Management -Protect hay when feeding by using rings to reduce waste. Unrolling hay increases hay waste unless it is done on a controlled basis.
-Consider using a temporary electric wire fence wire. This reduces waste from trampling and increases utilization of the hay.
-Unroll the bale, then string up an electrified polywire down the length of the line of hay.
-Place the wire about 30 inches high over the hay.
-Cattle will line up as if eating at a feed bunk.
