assess situation
Assess Situation
  • Inventory Cattle
  • Inventory Feed Supply
  • Do the numbers match?
animal management issues
Animal Management Issues
  • Pregnancy check, cull opens
  • Cull older, lower producing cows
  • Cull problem cows, disposition, arthritic, teat, udder and feet problems.
conduct a feed and animal inventory
Conduct a feed and animal inventory
  • Use ASC-78 as a guide
  • Group animals by their needs
  • Compare how much feed is needed vs what is on hand

are alternatives available on the farm
Are Alternatives Available on the Farm?
  • Corn that will make little or no grain yield
    • Chop it as silage
    • Do not graze or roll it for hay due to nitrates
  • Soybeans that will not set a bean
    • Graze or roll as hay, prevent bloat if grazing
    • Cut and roll when all leaves are still green
soybeans for hay or silage
Soybeans for Hay or Silage
  • For silage, harvest at R6 stage
  • May need to wilt after cutting
  • Forage beans yield 3-4 tons/ac of DM
  • Grain beans yield 2-3 tons/ac of DM
  • Animals do not like the silage, eat 20% less than corn silage
soybeans for hay or silage1
Soybeans for Hay or Silage
  • Hay may need to be harvested at a little earlier stage
  • Should be conditioned to crush stem or hard to cure
  • If too mature at cutting, will lose bean due to conditioning
  • May have feeding loss of up to 20% due to stem refusal
baling or grazing corn stalks
Baling or Grazing Corn Stalks
  • 120 bu corn = 4 to 5 tons residue/acre
  • Cows consume grain, leaves, husks, cobs, stalks in order
  • 1 acre of stalks = 30 days grazing/cow with mineral, protein supplementation
  • Should be strip grazed
  • Baling leaves much of the best (grain, leaves, husks) in the field
corn stalks
Corn Stalks
  • High Nitrates have been detected
  • Low quality feed
  • Requires protein and energy supplementation
  • Considerable waste in feeding
  • Stores poorly
what can i pay for silage
What can I pay for silage?
  • Based on previous estimate, hay costs $178.31 per cow to winter
  • How many tons of corn silage will it take to winter them?

=> 3.06 tons

  • You can pay $58.27 per ton of corn silage if hay is $125 per ton
slide31
Nutrient dense feeds such as grains, commodities, etc., are cheaper per unit of nutrient compared to hay.Be sure and compare on a dry matter basis.
stretch hay with supplement
Stretch Hay with Supplement

Feed the hay on hand and buy supplement

  • Corn will replace hay at the rate of 1.0 lb. Corn can replace 2.0 lb. of hay

Economics of Corn vs. Hay to Cows

*Corn purchased at $4.90 / bu from feed dealer

**Assumes 130 day winter feeding period

Assuming 130 Day Winter Feeding
  • Corn based may be cheaper depending on hay / corn price
  • Even if hay is cheaper, what is the goal?
  • Do we want to minimize costs, or maximize profit?
  • What is the value of a 21 lb increase in weaning weight and a 7% increase in conception rate?

Limitations
soy hulls
Soy Hulls
  • Excellent palatability
  • Less starch content than grains; therefore, less negative effect on forage utilization
  • Safer, less incidence of founder
corn gluten
Corn Gluten
  • By-product of soft drink industry
  • May be wet or dried
  • Corn gluten “feed” is around 22-25% CP; corn gluten meal is about 60% CP
  • Low starch
corn gluten feed
Corn Gluten Feed
  • High level of Sulfur (around 0.6%)
  • Limit to 50% of DMI due to its high sulfur content (Cu deficiency and polio)
challenges
Challenges
  • Transportation costs
  • Equipment needs for handling and storage
  • Rancidity
methods of ensiling
Methods of Ensiling
  • Silo Bags
  • Bunker Silos
  • Covered Piles
advantages of a 70 30 mixture 50 50 dm basis
Advantages of a 70:30 Mixture (50:50 DM basis)
  • Reduces dust in soybean hulls
  • Reduces seepage
  • Decreases CP content to 21%
  • Maintains high energy values
ensiling wdg with crop residues
Ensiling WDG with Crop Residues
  • On farm study
  • Blended corn stalks with MWDG
  • Blend was 60% DM
    • Cool at bag opening
    • Heated quickly

Garcia et al., 2004

recommendations
Recommendations
  • DM of blends should be no more than 50%
  • Drier blends do not preserve as well
  • Use of WDG over MWDG is preferred

You must maintain body condition

  • Calving

Energy Deficiencies Affect
  • Cow Rebreeding
  • Calf Health/Survival
  • Calf Growth Rate
timing of deficiency influences effect
Timing of Deficiency Influences Effect
  • Pre-calving deficiency  days of post partum interval
  • Post-calving deficiency  % conception
limit forage consumption
Limit Forage Consumption
  • Supplement Forage
  • Feed in Hay racks
  • Utilize all hay before moving rack
  • Delay feeding by 12 hours after roll eaten
  • Move feeding area to reduce mud
rumensin for wintering cows
Rumensin for Wintering Cows
  • 50 – 60% of total cost is winter feed
  • Prevent and control coccidiosis
  • Improved feed efficiency
  • Feed in 1 lb of feed daily

savings from limit hay feeding dry cows
Savings from Limit Hay FeedingDry Cows

* Hay valued @ $125 per ton

early weaning of calves
Early Weaning of Calves
  • Decreases nutrient needs of the cow
  • Cheaper to feed calf than cow
  • Calves as old as 50 days can be weaned
  • Feed conversion 4 to 5 lbs/lb of gain
  • Good health practices
  • Must be able to reach feed and water
sellout now and buy back in spring
Sellout now and buy back in spring?
  • Stock cows averaging near $650 this fall
  • Pairs ranged from $850 to $1,000 last spring
  • Wintering costs – (140 days @ $1.75) = $245
  • Mkt. value + winter feed savings = $850 to $950
  • Considerations
    • Prices for pairs this spring
    • Quality
    • Tax considerations
warning

Warning

Consider all alternatives before you pay too much for poor-quality large round hay bales or other sources of roughage.

long term adjustment
Long Term Adjustment
  • Store a surplus of hay (carry-over)
  • Consider some warm season grass pasture
  • Select cattle for reproductive efficiency
  • Calving season
