1 Webster County Diversified Agriculture Conference Presented By Andy McCorkill Livestock Specialist University of Missouri Extension Ph: (417)

2 Discussion Reasons for Supplementation Different Feedstuffs Practice Problem Determine Cows Needs Determine Forage Base Nutritional Value Determine Least Cost Option

3 Correcting Nutrient Deficiencies Maintain Proper Body Condition Optimal Production Levels Improve Profitability Nutrients of Focus Protein Energy Vitamins and Minerals

4 Improve Forage Utilization Allow animal to make better use of poor quality forages Stretch Forage Supply Replace part of the forage in the ration

5 Find a way to meet the needs of the animal Economical Fits in the management scheme of the operation

6 Forage!!! Cheapest, Most Economical

7 Convenience Feeds Advantages Easy to feed Less management required Disadvantage COST Examples Molasses based Lick Tubs Liquid Feed Range Cubes

8 Oilseed meals Excellent protein source Relatively high in energy Often used as an ingredient in limit fed mixes and lick tubs

9 Byproduct Feeds Good source of both energy and protein Highly digestible fiber Don t interfere with DM Intake like grains

10 Grains Good source of energy Can lead to reduced DM Intake

11 Size Large vs. Small Body Condition Thin vs. Fat Stage of Production Age Heifers vs. Mature Cows Level Production (Milking Level)

12 What Does Your Cow Really Need? Requirements % Crude Protein X Dry Matter Intake (lb./day) = pounds of CP % Total Digestible Nutrients X Dry Matter Intake (lb./day) = pounds of TDN Hay/Forage Supplies % Crude Protein X Dry Matter Intake (lb./day) = pounds of CP % Total Digestible Nutrients X Dry Matter Intake (lb./day) = pounds of TDN What else does she need? CP Requirement - amount supplied by hay = lbs. CP needed TDN Requirement - amount supplied by hay = lbs. TDN needed Least cost feed Feed 1 Cost per pound / % DM / % CP = Cost per pound of protein Cost per pound / % DM / % TDN = Cost per pound of energy Feed 2 Cost per pound / % DM / % CP = Cost per pound of protein Cost per pound / % DM / % TDN = Cost per pound of energy Feed 3 Cost per pound / % DM / % CP = Cost per pound of protein Cost per pound / % DM / % TDN = Cost per pound of energy Feed 4 Cost per pound / % DM / % CP = Cost per pound of protein Cost per pound / % DM / % TDN = Cost per pound of energy

13 1200 pound cow in first 90 days of lactation Producing 20# milk

14 1200 pound cow in first 90 days of lactation Producing 20# milk Requirements: 9.8% CP 58% TDN 30# DM

15 What Does Your Cow Really Need? Requirements % Crude Protein 9.8 X Dry Matter Intake (lb./day) 30 = 2.9 pounds of CP % Total Digestible Nutrients _58 X Dry Matter Intake (lb./day) _30 = 17.4 pounds of TDN Hay/Forage Supplies % Crude Protein X Dry Matter Intake (lb./day) = pounds of CP % Total Digestible Nutrients X Dry Matter Intake (lb./day) = pounds of TDN What else does she need? CP Requirement - amount supplied by hay = lbs. CP needed TDN Requirement - amount supplied by hay = lbs. TDN needed / % DM / % TDN = Cost per pound of energy

16 Fescue/Red Clover Hay 87% DM 11% CP 54% TDN Feeding 27#/hd/day

17 What Does Your Cow Really Need? Requirements % Crude Protein 9.8 X Dry Matter Intake (lb./day) 30 = 2.9 pounds of CP % Total Digestible Nutrients _58 X Dry Matter Intake (lb./day) 30 = 17.4 pounds of TDN Hay/Forage Supplies % Crude Protein _11 X Dry Matter Intake (lb./day) _27 = 3.0 pounds of CP % Total Digestible Nutrients 54 X Dry Matter Intake (lb./day) 27 = 14.6 pounds of TDN What else does she need? CP Requirement amount supplied by hay 3.0 = 0 lbs. CP needed TDN Requirement amount supplied by hay 14.6 = 2.8 lbs. TDN needed

18 Feed 1 Soybean Meal $20.90/CWT Feed 2 Distiller s Dried Grain 13.55/CWT Feed 3 Corn Gluten Pellets 13.20/CWT Feed 4 Soy Hull Pellets 13.15/CWT

19 What Does Your Cow Really Need? Least cost feed Feed 1 Cost per pound _.209 / _91 % DM / 54 % CP =.43 Cost per pound of protein Cost per pound _.209 / _91 % DM / 87 % TDN =.26 Cost per pound of energy Feed 2 Cost per pound.1355 / 90 % DM / 30 % CP =.50 Cost per pound of protein Cost per pound _.1355 / _90 % DM / 92 % TDN =.16 Cost per pound of energy Feed 3 Cost per pound _.132 / 90 % DM / 24 % CP =.61 Cost per pound of protein Cost per pound _.132 / 90 % DM / 80 % TDN =.18 Cost per pound of energy Feed 4 Cost per pound.1315 / 90 % DM / 12 % CP = 1.21 Cost per pound of protein Cost per pound.1315 / 90 % DM / 77 % TDN =.20 Cost per pound of energy

20 Calculations TDN on an As Fed Basis %TDN (from chart) x %DM How much is required??? Total required additional TDN/% TDN on an As Fed Basis Total cost/hd/day Amount of total feed required x price/#

21 Feed 1 (SBM).91 (%DM) x.87 (%TDN) =.79 % TDN as fed 2.8# (total additional TDN)/.79= 3.6#/hd/d 3.6#/hd/d x.21= $0.76/hd/day Total Supplementation Cost

22 Feed 2 DDG.90 (%DM) x.92 (%TDN) =.83% TDN as fed 2.8# (total additional TDN)/.83= 3.4#/hd/d 3.4#/hd/d x.14= $0.48/hd/day Total Supplementation Cost

23 Feed 3 (Corn Gluten Pellets).90 (%DM) x.80 (%TDN) =.72% TDN as fed 2.8# (total additional TDN)/.72= 3.9#/hd/d 3.9#/hd/d x.13= $0.51/hd/day Total Supplementation Cost

24 Feed 4 (Soy Hull Pellets).90 (%DM) x.77 (%TDN) =.69% TDN as fed 2.8# (total additional TDN)/.69= 4.1#/hd/d 4.1#/hd/d x.13= $0.53/hd/day Total Supplementation Cost
