Ration Balancing Made Easy
Contact your local county Extension office through our County Office List. Print this fact sheet. 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.

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.

This tool calculates average mineral intake for a mineral that is fed to your cattle. It includes average intake over time and graphs average intake between times you place mineral in your pasture. It can account for mineral remaining in the feeder and changes in number of cattle in the pasture. Mineral Consumption Record : Program. OSU Cowculator is a Windows based Computer software program designed to assist cattlemen in making informed decisions associated with beef cownutrition. Animal criteria such as cow weight, body condition, stage ofproduction and breedas well as the feed and forage library can be customized to each operation or to specific scenarios within an operation. Animal requirements and performance predictions are based on years of research data,including the and previous versions of the National Research Council'sNutrient Requirements of Beef Cattle. This decision aid provides a framework for the user to record beginning and ending inventories for various cattle and horse categories. Spreadsheet documents the sale or transfer of cattle between production activities. The reports provide a summary by cattle category with associated pay-weight and price per hundredweight. Cowgame is a beef herd genetic simulation program. The player starts with a fifty cow herd and makes selections based upon weaning weight, feedlot gain or yearling weight. The next year's calf crop is generated during each session and the genetic information is saved so that future selections can be made. AI sires can also be used. Calculates the inbreeding of all individuals in a given pedigree that may be stored as a data file or entered directly into the portion of the program that calculates inbreeding. Economic aspects of preconditioning programs. From these inputs, the program calculates net operating returns and annual cash flow for the ranch under different production-marketing alternatives available to the manager. From data entered by the user, this program generates profit or loss by industry segment for purebreds, two-breed terminal, three-breed terminal, three-breed rotational and three-breed special cross. It is capable of using up to 14 different breeds of cattle. Preconditioning is the practice of preparing calves for the stresses encountered during the transition from nursing to confined feeding. The concept has existed since the large-scale cattle feeding industry first evolved in the late s. The goals are to overcome the stress of weaning, teach calves to eat milled feed, administer appropriate immunizations, reduce sickness and increase the value of the calves to cattle feeders. The OQBN Vac program is a preconditioning program that allows producers to third party verify their preconditioning efforts. This tool lets you estimate the cost of participation in the program versus your projected returns. Equitable breeding livestock agreements can take many forms as parties contribute land, labor, management and cattle differently. This Excel spreadsheet assists in valuing contributions and evaluating alternative share arrangements. Spreadsheet : Publication : Fillable Form. The program is useful for enterprise budgeting, estimating transportation costs, and evaluating purchasing alternatives.
