Total mixed dairy rations (TMR) offer an opportunity to improve business profits through improved animal performance and health, decreased feed wastage, improved labor efficiency and improved butterfat. The installation of a TMR system normally requires added investments in feed mixing and distribution equipment. Additional storage facilities may be required as well.

With a TMR system, each bite is a balanced diet. For small herds, a limiting factor influencing milk production is balancing the ration for the broad range of production levels within the herd. Diets too low in energy and protein may limit production of early lactating cows or result in thin cows with lower production and reduced reproductive efficiency. In contrast, diets too high in energy and protein can result in overconditioned cows at freshening with fat cow problems. In larger herds, cows can be grouped more homogeneously to better balance for nutrient requirements.

The purpose of this publication is to provide a format for evaluating the economic consequences of changing to a TMR system. Planning will enable you to determine what investments, labor costs, power costs, etc., are needed to implement the system before making new investments or changes in your operation.

Adopting the TMR feeding system will change your dairy enterprise costs and returns. To evaluate this change, the following partial budgeting procedure (economic analysis) will allow you to balance expected total gains against losses that will result if you switch from parlor grain feeding to a TMR.

The following budgeting procedure allows you to estimate:

This "ballpark" analysis will help determine if the potential added returns will outweigh the added costs, indicating whether the proposed change will be profitable for your operation.

Brief instructions follow:

Item 3 provides guidelines and a method for calculating tractor power costs that are necessary to operate the mixer wagon and front-end loader. Tractor costs are allocated to TMR on a cost per hour of operation basis because the tractor is usually used for other business activities. Thus this is an easy method of allocating this specific cost to TMR. Because labor and machinery operate together, the hours per cow are the same as the labor hours used in Item 2. Also, you can use variable or total costs per hour of tractor operation. For example, if the tractor you plan to use is an older tractor that is fully depreciated, it would be appropriate to use variable costs only. But if you have a newer tractor or have to purchase a tractor specifically for the TMR system, you should use total costs per hour of operation to calculate power costs.

Items 4 and 5 are self-explanatory. Just fill in the blanks and calculate the answer. Note that the marketing costs in Item 4 are based on hundredweight of milk, not pounds.

Item 6 may not be a cost to you. If it isn't, leave it blank.

Summary

The Partial Budget Analysis Worksheet allows you to estimate the rate of return from the investment needed to implement a total mixed ration system in your dairy operation. The answer calculated on line D3 indicates whether the change has a potential of producing a positive or negative annual profit. Line D4 converts the dollar profit into a percent return to the additional capital needed to make the change, i.e., from parlor feeding to TMR system. For this reason the major capital investments needed for the TMR system should be identified and analyzed as accurately as possible.

The actual increase in milk production and the milk price received will vary. Therefore, two or more analyses based on different levels of increased milk production per cow such as 500, 750, 900, 1,200 pounds and at different price levels such as $11, $12, $13 per hundredweight should be calculated. At least a best-case and worst-case scenario should be thought through and analyzed to develop a bracket in which you will be operating.

Producers who feed balanced, palatable rations can expect less productive gains from TMR (lower benefit levels) than others whose rations fall short of nutritional requirements. Under such conditions, producers should experience the higher gains per cow.

Another important consideration is the investment requirement from a total business perspective. If higher outlays for equipment and power are required and must be obtained by borrowing money, debt service becomes an important risk consideration. This could be judged in terms of cash flow obligations to service debt and whether the added debt influences the financial statement of the total business in an adverse fashion (debt/equity ratio).

Section B: Added Returns and/or Reduced Costs

Estimated increase in value of milk production:

Present average annual milk production per cow is _______ pounds(a)
Expected increase in production per cow (Guide 3 to 10 percent) _______ pounds(b)
Projected milk price (3.5 percent) per hundredweight. $_______ plus value for 0.1 percent butterfat _______ cents per hundredweight. is projected price for 3.6 percent milk $_______ (c)

  1. Value of increased milk production

    _____ number of cows x _______ (b) pounds increase per cow = _______ total pounds milk/100 = _______ hundredweight x $_______ (c) price for 3.6 percent milk = $_______

  2. Increased value of butterfat for present production

    _____ number of cows x _______ (a) pounds present production per cow = _______ total pounds milk/100 = _______ hundredweight. x _______ cents per hundredweight. per 0.1 percent added butterfat = $_______

  3. Reduced feed wastage (3 to 5 percent of total feed cost)

    Feed cost guides based on milk production per cow:
    12,500 pounds = $1,050; 15,000 pounds = $1,150
    18,000 pounds = $1,250; 20,000 pounds = $1,300
    _____ number of cows x $_______ feed per cow = total value fed x _____ percent wastage = $_______

  4. Other returns or reduced costs (i.e., salvage value of old feeding system) $_______
  5. Total estimated added returns (Add lines 1 through 4) $_______
    1Know horsepower requirement to operate. Will you need to buy a tractor to operate or can you use your present tractor?
    2Do not include hay, grain or silage storage investments. Feed costs included in Section B3 are based on market value plus transportation and storage costs, therefore investments for hay, grain and silage storage should not be included.

Section C: Added Costs and/or Reduced Returns Associated with the TMR System

  1. Added feed cost1 (Use only the extra grain ration required for the added production)

    Increased milk production ___________ pounds per cow per ___________ milk per feed ratio2 (Guide 2 to 3 pounds) = __________ pounds grain ration x _________ cents per pound x ____________ number of cows = $__________

  2. Labor costs

    Guides for added labor for TMR system per cow by herd size: 100-cow herd — 5.5 hours per cow; 200-cow herd — 4.1 hours per cow; 300-cow herd — 3.7 hours per cow; 500-cow herd — 3.6 hours per cow
    ____________ hours per cow x ___________ number of cows x $__________ per hour. = $_______

  3. Power costs (use variable costs for tractors presently owned and total costs for purchased tractor for the TMR system)

    Guides for tractor costs:
