Welcome to the EZ Ration Processor!

This SDSU Extension calculator is designed to assist producers with supplemental feed purchase decisions. There are many feedstuffs available that provide protein or energy. The price of these products, based on the nutrients they provide, should be used to develop the best, low-cost balanced ration for the enterprise. To use this calculator producers will need to know the price per unit of the feedstuffs available for purchase, the mileage to deliver the feedstuffs, and the cost of delivery for the feedstuffs. Additionally, for accurate calculations, the feed values of the available options should be entered. Base nutrient analysis for common feeds are listed in the calculator. Evaluation of feedstuff costs, on a nutrient basis, will provide producers the opportunity to create least-cost rations for their livestock enterprises. As feed is the largest expense in any livestock enterprise this is a critical decision making process. Disclaimer: The preceding is presented for informational purposes only.

FEEDING CALCULATORS & CHARTS


Feed is the single largest cost associated with raising small ruminants. Sheep and goat producers should balance or evaluate feed rations to make sure they are meeting the nutritional requirements of their animals. Ration balancing can ensure optimal animal performance, prevent nutritional problems, and manage feed costs. There are two ways to balance feed rations: by hand using paper and pencil or with a computer with or without the Internet. Rations can be balanced manually using simple arithmetic. The Pearson Square and simultaneous algebraic equations are common methods of ration balancing. Computers and the internet can make ration balancing easier. Tedious tasks are automated, arithmetic errors are eliminated, and the programs are preloaded with nutritional requirements and feed libraries. Several software options are available for sheep and goat producers. Programs vary in their cost, user interface, and features. The Standard Edition for sheep Ewe and Feedyard balances rations for energy, protein, vitamins, and minerals using the substitution method. They also calculate cost of gain and feed cost per head per day. The Goat Nutrition Standard Edition Modules are designed for ration evaluation and manual formulation of growing and mature dairy, meat, and mohair goats. The software utilizes the guidelines outlined in the National Research Council's publication The Nutrient Requirements of Small Ruminants as the primary basis for these guidelines. They will run on a PC or Mac. The ISU Sheep Feedlot Monitor Software is specialized to assist sheep feedlot managers with both detailed monitoring of animal performance along with business transactions involving the sheep feeding enterprise. Both programs offer least-cost and analysis or evaluation options for ration balancing. Free demo versions of the software can be downloaded from the web site. It uses the substitution method of ration balancing. Because its nutritional recommendations are based on the NRC requirements 6th Revised Editionone of the limitations of the MSU Sheep Ration Program, is that it does not allow you to balance rations for high producing ewes triplets or better or parlor-milked dairy ewes. The program is also not suitable for goats, unless you use sheep nutritional requirements. While you can add or edit feeds, you cannot add an animal or modify animal requirements. Feed specifications and rations are stored on the MSU server.

The Pearson square or box method of balancing rations is a simple procedure that has been used for many years. It is of greatest value when only two ingredients are to be mixed. In taking a close look at the square, several numbers are in and around the square. Probably one of the more important numbers is the number that appears in the middle of the square. This number represents the nutritional requirement of an animal for a specific nutrient. It may be crude protein or TDN, amino acids, minerals or vitamins. Corn represents Soybean meal represents 4. Check of the calculation:. It is possible to mix more than two ingredients using the Pearson square. For example, to prepare a 15 percent crude protein mixture that consists of a supplement of 60 percent soybean meal 45 percent crude protein and 40 percent corn gluten meal 45 percent crude proteinand a grain mixture of 65 percent corn 9 percent crude protein and 35 percent oats 12 percent crude proteintake the following steps. Since only two components can be used in the Pearson square method, the ingredients are combined first as follows:. The crude-protein value of a feed or the percentage of any other component e. The two most common methods of expression are on an as-fed basis or dry-matter basis. Use the following procedure to calculate composition on a dry-matter basis. Crude protein value on an as-fed basis divided by dry-matter content of the feed times equals the crude-protein content on a dry-matter basis. If alfalfa hay is used as an example, the crude protein value is 17 percent on an as-fed basis. To determine the total digestible nutrient TDN content of the above alfalfa on a dry-matter basis, follow the same procedure: 50 percent TDN value on an as-fed basis divided by 0. Likewise, the crude-protein content or the TDN value also can be expressed on the basis of any given dry-matter level. For example, if you use a percent dry-matter basis, use the following calculation. Given a TDN value of 76 percent and a dry-matter content of 86 percent 14 percent moisturewhat would be the TDN value of this feed on a 90 percent dry-matter basis? If you know the dry-matter composition of a specific ration and want to determine what that composition will be on an as-fed basis for mixing, make the calculations shown in Table 1.

Pearson's Square also called the Pearson Square, the box method, the rectangle method is a great tool to help you determine the proper mixture of two different feedstuffs to reach a particular nutritional percentage. This is a particularly useful tool when you're trying to combine feedstuff for winter feeding or to simply optimize your animals' intake for proper growth and health while not having any feed waste. Normally you would have to do the math manually. We wanted to give you an easier way to get your mixed ration calculations done quickly, so we built a Pearson's Square calculator for you to use. Follow the steps below to use the calculator. Ingredients in a mixture must be calculated on the same basis. We have set the calculator up so that all nutrient percentages displayed are based on your chosen basis. The target percentage must be between the percentages of your feedstuffs for the calculation to work. Example: A protein mix of Bromegrass Select the two feedstuffs you want to balance. We have an extensive list of options and their nutrient percentages, taken from the National Research Council's publication, Nutrient Requirements of Small Ruminants. If you have tested your feed and know their values, overwrite the default percentage to match your specific feedstuff by typing your number over the value in the percentage field for a more accurate calculation. If the feedstuff you're using is not in our list, type it over any value in the feedstuff name field, and its percentage over the value in the percentage field to get a result with your specific feedstuff. Your results will be expressed both in the parts and percentages of each feedstuff required to meet your target nutrient percentage. If results are not displayed after completing steps 1 through 3 above, check that all fields have information in them and that your target percentage is between the two feedstuffs. If you'd like to see an example of where a Pearson's Square could come in handy, check out our Fundamentals of goat nutrition article contributed by Dr. Frank Pinkerton. If you use a feedstuff or nutrient you would like us to add to the calculator, please send an email to support easykeeper. The percentages included in this Pearson's Square are only generalizations or averages of nutrient composition provided by the "Nutrient Requirements of Small Ruminants", published by the National Research Council. Actual analyses should be used when formulating rations. EasyKeeper Herd Manager assumes no liability for rations developed using the information included in this nutrition calculator.

Fear not, gentle reader. This is nearly always the case when you feed a commercial ration without supplements; and only during growth especially in the first yearlactation, and the last three months of pregnancy are horses likely to need extra nutritional support. With the exception of salt and water, horses do not develop cravings for the nutrients they require; they simply function according to appetite and taste preference, just as humans do. Fortunately, most of these are known to be provided in adequate amounts by any common equine diet. Or, at least, there are no documented cases of clinical deficiencies or toxicities. We know that horses have a need for trace amounts of sulfur in their diets, for example, but there has never been a documented case of sulfur deficiency, so we safely assume that all equine diets deliver enough sulfur for their needs. As a result, we can zero in on a few key nutritional elements, for which deficiencies or excesses might occur—protein, digestible energy DEcalcium, phosphorus, and selenium. Levels of vitamins A and E also might be a concern for growing horses and those in high-performance situations, especially in the winter months when they have no access to growing forage. These will have an important bearing on the concentrations of nutrients they require. For example:. What stage of life is your horse in? Are you feeding a growing foal, a lactating broodmare, an adult pleasure horse, or a mile endurance champion? Is your horse idle, or doing work of light, medium, or serious intensity? Medium work is perhaps up to an hour a day of trotting and cantering, such as might be required of a dressage horse or working cow horse. Intense work usually is considered such strenuous tasks as playing polo, racing, or upper-level three day eventing, where the horse is exercising at a high-performance level for more than an hour a day. Is his workload due to be increased, decreased, or remain constant? What feeds are available to you? Which are reasonably priced? Incidentally, heart-girth tapes are of no use for pregnant mares; their heartgirths alone will not tell the story. The total weight of feed per day should be between 1. If, for instance, you owned a Standardbred mare who weighs pounds, our rule would suggest that she would need between For example, if your mare is overweight and only in light work, you would lean toward the lower end of the scale, at If, on the other hand, she was in top physical condition and was competing in a high-intensity sport like harness racing or upper-level combined driving, she might require closer to 28 pounds of feed a day to provide her with the energy she needs. The 1. Intense work, lactation nursingand growth all need to be fueled by larger amounts of nutrients. To some extent, the intake also will be affected by temperament laid-back, easy keepers will be at the lower end of the scale, while nervous or high-strung horses which are hard keepers will need moreand climate because it takes more energy to maintain internal body temperature in below-freezing weather. Most horse people, of course, are used to feeding by volume this horse gets half a scoop, this one a whole scoop, that pony a handful. They also vary in regard to the number of flakes they contain. And some grains are far heavier and more energy-dense than others. For example, a one-quart scoop of corn will have considerably more energy than a one-quart scoop of oats. So if you feed that quart to a horse which is used to oats, you might have one wired-for-sound horse on your hands! The simplest way to determine the weight of a hay bale is to bring your bathroom scale out to the barn. Stand on it empty-handed to find your own weight, then repeat the process while hoisting a bale of hay. Then crack open a couple of bales and weigh yourself holding some representative flakes.
