1. Take Home Message #2Shredlage &Forage Form
2. Visualizing the Rumen Mat
3. Physically effective fiber Providing 5 pounds of feed particles over 0.75 inch to 2 inches 550 to 600 minutes of cud-chewing activity per cow per day. 60 to 75% of cows at rest should be cud-chewing > 60 chews per bolus of feed. Rumen pH should be over 6.0
4. Shredlage vs. Kernel Processing Longitudinally ripped forage (increase surface area) Stalk pieces about the size of an alfalfa steam (1.25 inch TLC or 30 mm) Rhine of plant completely opened up. Smashed corn kernels Softer and fluffier.

Shredlage processor Processor costs ~ $30,000 Additional $25/hour to cover extra fuel & other costs Estimated 2 gallons more fuel per hour ShredlageLLC recommends that custom operators charge $1.50-$2/ton Custom harvesters estimate roll replacement on one roll at 40,000-50,000 tons and maybe both rolls at 60,000-70,000 tons Custom Harvesters Tell How Shredlage Works For Them New silage corn processing method is examined - Apr. 15, 2013 http://hayandforage.com/corn/custom-harvesters-tell-how-shredlage-works-them

16. Take Home Message #3 Build Your Milk Check
17. Never Give Up Milk 1 lb of dry matter cost $0.12 Milk price is $0.20 per pound Good cows produce 2 lb of milk per 1 lb of DM Profit: $0.28 cents per cow per pound of DM
18. Value of Milk Components(Prices for November, 2013) Holstein herd: 70 lb milk, 3.5% fat , and 2.9% true protein corrected to 3.7% fat and 3.0% true protein 70 lb x 0.2% point increase = 0.14 lb of milk fat x $1.63 / lb fat = $0.23 70 lb x 0.1% point increase milk protein = 0.07 lb protein x $3.63 / lb = $0.25 Profit potential: $0.48
19. Milk Fat and Milk Protein Relationship(Hoard’s Dairyman—Aug, 2013) Protein Fat vs Fat % Protein % vs Fat Protein 3.86 3.17 80% 1.22 Ayrshire Brown Swiss 1.22 3.96 3.30 83% 4.49 1.36 Guernsey 3.31 74% Holstein 1.23 3.70 3.02 82% Jersey 4.75 3.64 77% 1.30
20. Case Study: U of IL Dairy Farm Item Added Value /cwt Milk fat is 3.9% + 23 cents Milk true protein is 3.1% + 25 cents Milk quality premium + 83 cents rBST premium not to use + 59 cents

40. Take Home Message #7Replacement Heifers
41. Cost of Raising Heifers(33 WI operations in 2013) Feed costs $1046 Labor and mgmt costs $ 333 Variable costs $ 274 Fixed costs $ 209 Total $1,862 (Add calf value and calf costs of $363)
42. Looking Back 1999 2007 2013 Total Cost $1099 $1323 $1863 Daily Cost $1.61 $2.04 $3.04 Days on Feed 683 648 611

44. Points to Ponder Do you raise all female replacement heifers? Does genomics allow identification of superior animals? Do you use sexed semen on the best heifers and cows? Do you breed the bottom 1/3 cows to beef bulls?
45. Take Home Message #8Grouping Cows
46. Economics of Three Production Groups Milk yield Feed cost DMI Cost (lb/cow) ($/cow/day) (lb/day) ($/lb DM) 85 6.58 49.8 0.132 76 5.05 42.7 0.112 41 3.80 35.3 0.107
47. Economics of 85 lb vs. 76 lb TMR 1. Savings with two rations approach is $1.53 Adjusting for lower DMI $0.86 (42.7 lb x 13.2 cent/lb = $5.64 day (42.7 lb x 11.2 cent lb = $4.78 day Milk loss when shifting cows (4 lb @ 19 cents) $0.76
48. Grouping Software Program Dr. Victor Cabrera, U of WI Compare one group vs. to 2, 3, or 4 groups Download your DHI herd data (milk yield, components, DIM, and body weight) Protein and energy costs Current milk prices
49. Grouping Software Program Enter the loss of milk yield per cow Number of days of lost milk production Added costs of mixing rations Savings on additives Comparison of IOFC: Cluster (cows with similar needs) Dairy Merit (milk yield and body weight at .075 power) FCM (fat corrected milk) DIM (days in milk)
50. Ration Selection Cluster approach Four lactating groups 120/120/120/110 cows per group 16.5% CP 0.73 Mcal / lb DM 15.1%CP 0.68 Mcal/ lb DM 14.4%CP 0.66 Mcal / lb DM 13.2%CP 0.62 Mcal / lb DM
51. Economic Comparisons 1 vs 2 group $ 27,628 per year 1 vs 4 group $103,957 per year 2 groups 300 / 170 $1,359,105 100 / 370 $1,346,952 235 / 235 $1,359,108

54. Control / Measuring Shrink Measuring weigh-backs (1% to 2%) Reducing feed losses Forages (5 to 35%) Concentrates (2 to 10%) By-products (5 to 10% Environment: moisture, wind , birds, mold
55. Must Use Silage Inoculants 3% improvement in dry matter recovery 2% increase in digestibility Benefit to cost ratio ($1 per ton) 3 : 1 on nutrient preserved 8: 1 when fed to high producing cows
56. Oxygen Barrier Covering 60 times more reduction in oxygen penetration in wet silage (using OTR or oxygen transfer rate comparisons) Reduces DM loss by 50% in the top 1.5 to 3 feet of silage Results in a 2 to 5% savings in dry matter retained
57. Take Home Messages Cows are always “talking” to us Select areas that may give you the biggest “bang” for your time Monitor values so when changes occur, you / we have a base line
58. Make Economic-Based Long Term Correct Decisions Maintain a solid mineral program Holstein heifers must gain 1.6 – 1.8 lb / day SCC must be below 200,000 Days open must by under 120 days Accelerated calf program is a must Select additives that pay Consider a low group TMR
59. Feed Changes: Cow Responses Change in MUN by 3 units (8 to 12) Change in manure score by one unit (3.0) Change in body condition score by 0.5 (3.0) Change > 3 lb of management level milk Change > 0.2 % milk fat unit Change > 0.1% milk protein unit Change 2 lb of dry matter intake
