4. Components of Hay Losses: Field curing Harvesting Storage Feeding

5. Storage 20-45% loss Harvesting 7-15% loss Feeding 10-30% loss Field curing 10-25% loss It’s not unusual to see total losses of 70% or greater LOSS ACCUMULATE WITH EACH STEP

7. The True Cost of Storage and Feeding Losses About 3 billion dollars of hay is lost per year from storage and feeding in the U.S. (37.5 million tons)

16. Hoop Structures for Hay Storage

17. Adjustable tension to keep cover tight

18. Hoop Structures for Hay Storage Cost: Package (hoops, cover) $6,000-7,000 Posts, concrete, lumber, gravel, labor = $1,000-3,000 Total Materials Cost = ~ $7,500 - 10,000 250-300 bales Assuming 10-year structure life (prorated 16-year warranty on cover) $10,000/10 yr = $1000 per year $1000/300 bales = $3.00 per bale

19. Tarped Stacks Hay Sheds Hoop Structures Storage Options $1.50 – 2.50 $2.00 – 3.00 $3.50+

20. Long-term Hay Storage DM Loss (Undercover)  5% 1 st year, little thereafter Net wrap or plastic sleeves  5-8% 1 st yr, 2-5% ea yr Twine on the ground  Don’t even think about it! Vitamin A content of old hay DM Loss (Undercover)  5% 1 st year, little thereafter Net wrap or plastic sleeves  5-8% 1 st yr, 2-5% ea yr Twine on the ground  Don’t even think about it! Vitamin A content of old hay

21. By-products Viable option when hay is > ~$80/ton Must be purchased in bulk loads Storage – under shelter, grain bins, gravity flow wagons Most cases – need a feed trough Feeding (other than a shovel) is the biggest obstacle for most people

22. Comparison of Relative Energy Values Maintenance energy Corn 1.00 Hay 0.50-0.70 Cottonseed 1.00 Soybean hulls.88 Corn gluten feed.88 Distillers grains.99

23. Choices of By-Products 1.Soybean hulls  Low starch, moderate protein, high intake  Bloat 2.Corn gluten feed  Low starch, high protein (good complement to low quality hay)  Limit to 25% of diet, high sulfur, low Ca:P 3.Whole cottonseed  High energy (fat) and protein  Limit to 0.5% of diet 1.Soybean hulls  Low starch, moderate protein, high intake  Bloat 2.Corn gluten feed  Low starch, high protein (good complement to low quality hay)  Limit to 25% of diet, high sulfur, low Ca:P 3.Whole cottonseed  High energy (fat) and protein  Limit to 0.5% of diet

24. What about distiller’s grains? Fairly comparable to corn gluten feed  Probably will need to limit to less than 20% Big difference between wet and dried DGs  Dried: Energy expense = added cost  Storage needed  Wet: Transportation expense = added cost  Storage needed  Perishable product  High feed-out rate Fairly comparable to corn gluten feed  Probably will need to limit to less than 20% Big difference between wet and dried DGs  Dried: Energy expense = added cost  Storage needed  Wet: Transportation expense = added cost  Storage needed  Perishable product  High feed-out rate

25. Stretching Hay with By-Products In general, by-products are great ways to stretch short hay stocks.  1 lb of feed replaces about 1.5 to 2 lbs of hay Again, feeding (Supplements, TMRs, or Hay) is almost always more expensive than grazing.
