1/21/2024 0 Comments Pasteurization unit calculationThe cost and nutrient value of whole milk can be taken from your milk check. The amount of water is needed to calculate the cost of hot water used in mixing milk replacer. Be sure to enter the amount of powder fed to each calf each day and the amount of water mixed with that powder. Dry matter content will likely not be listed, but it typically ranges from 96 to 98%. Milk replacer nutrient information can be found on the tag. The next section of input gathers nutrient and cost information about the feeds you offer to calves. Labor costs may include an adjustment for benefits in addition to wages. In the fourth section, enter your costs for various types of energy and for labor. If you do not use a mixer for milk replacer, leave these items blank or enter zeroes. The annual cost of the mixer is not included because the purchase price is typically a minimal expense. Hot water used in cleaning the mixer is not counted. This spreadsheet accounts for the costs of heating hot water (in an electric water heater), electricity used in running a mixer, and soap used to clean the mixer. Section three collects information about milk replacer mixing. If you are evaluating a batch pasteurizer, the time required to process a batch should include the process from start to finish, both heating milk and cooling to feeding temperature. It is not necessary to delete the information under the other type of pasteurizer. In addition to this first section, be sure to enter information under the appropriate heading for the pasteurizer you want to evaluate. For the additional labor line, be sure to include only the extra time needed to operate the pasteurizer compared to feeding milk replacer, not the entire time required to feed. The first part of this section applies to both batch and continuous flow high-temperature, short-time (HTST) equipment. The next section requires information about the operation of the pasteurizer. The interest rate is entered as a whole number. If any of the components is not needed for your installation, enter a zero for the purchase price and leave the years of life blank. In the first section, capital investment, the purchase price and years of life for each component of the pasteurizer system are entered. Instructions for InputĪll information to drive the economic calculations of the spreadsheet is entered on the "Input" worksheet. The final components of the spreadsheet are two simple calculators that estimate the supply of and demand for waste milk and calculate the amount of powder to add to waste milk to increase solids or volume. Additionally, the spreadsheet offers tables that compare the costs of alternatives to feeding pasteurized milk when the supply of waste milk is not adequate to feed all calves. Additionally, the cost of each feed is expressed on a crude protein basis for comparison of cost-to-value. Of course, adequate nutrient intake is very important, and the amount of fat and protein provided to calves is presented for each feed option for this reason. We chose not to do this because many variables other than nutrient intake affect the actual growth and health performance of calves. The spreadsheet calculates costs and nutrients fed, but does not evaluate calf health or growth for each option. All nutrient values can be edited to compare a variety of feeding programs. The spreadsheet also provides a comparison of the nutrients provided by milk replacer, waste milk, and whole milk. This spreadsheetcalculates the cost of owning and operating a calf milk pasteurizer as well as costs to feed milk replacer or whole, saleable milk. In addition, pasteurization does not reduce the amount of antibiotic residues or bacterial toxins that may be present in waste milk. Some potential considerations are an economic analysis, estimation of daily waste milk supply, and provision for feeding calves when the waste milk supply is not adequate. While it is now possible to recover the feed value of waste milk with much lower disease risk, it is important to carefully evaluate your situation before the decision to install a pasteurizer is made. Prior to the introduction of such systems, feeding waste milk was considered risky, primarily due to the potential for spreading disease. Commercial systems for pasteurizing milk fed to calves have become available in recent years.
