So, eight ewes are one animal unit (meaning that eight ewes consume about 26 pounds of forage daily). This equals 12.8 animal unit days of grazing per acre (225 divided by 17.64 pounds per day) before grazing must be stopped until regrowth occurs. Note that animal density should be much higher than 0.5 if animals are only grazing the pasture a fraction of the time. 566 0 obj <> endobj xref 566 38 0000000016 00000 n Forage and Grazing Terminology Committee. It is typically expressed as acres per animal unit. The most common cause of degradation is simply that ranchers expect animal productivity from their rangelands to be much higher than is realistic (Pressland and Graham, 1989). Our work makes a difference, in the lives of Texans and on the economy. Stocking Rate Determination on Native Rangeland. 0000005691 00000 n Convert for Animal type you are using with Animal Unit Equivalents: Animal Unit Months for your animal = Stocking Rate Animal Unit Equivalent 6. Determine stocking rate, plan paddock sequences and use tactical grazing to maximise conversion of pasture into beef Guidelines for tactical grazing by planning paddock sequences. Heavier stocking rates require earlier removal of cattle from the system, but this strategy would allow a longer recovery period for the pasture. This figure is used because livestock need to have 4% of their weight in forage each day (2.5-3% intake, .5 trampling loss and .5-1% buffer). When stocking rates and grazing times are determined by this forage supply/forage residue approach, there is time for the rancher to predict potential forage shortfalls, determine the impact of the decision on finances and other ranch resources, and make any necessary adjustments before the forage resource is harmed or financial problems occur. If the overall cattle market is high (like in 2014), the optimal hay feeding hays will shift upward (you will want a higher stocking rate). The decisions that will achieve successful ranch management are different for each enterprise because each ranch has its own resources. College Station, Texas, pp. Financial obligations often “force” a rancher into selecting a stocking rate too high for the forage supply available. L. D. and C. Richardson. Stuth (eds.). How Do I Determine the Correct Stocking Rate? With intensive management, including frequent stock rotations, it is sometimes possible to achieve a slightly higher harvest efficiency by getting animals to consume forage before it is lost to trampling, weathering and other causes, However, 25 percent hat-vest efficiency is considered a moderate stocking rate and is the level most ranchers should strive for. A stocking rate refers to the number of animals per unit area for a given period of time. This is always the same number, .04, or 4%. 304-309. The stocking rates contained within this publication are generalized for Saskatchewan soil zones and represent average stocking rates under various conditions. Average Stocking Rates for Alabama Beef Cattle Operations Table 2 shows average stocking rate potential across various soil-climate regions of Alabama. Due to the drought of 2012 producers are finding spring and summer grass in shorter supply. Researchers Study Modified Intensive-Early Stocking Rates. 2.5 cows per hectare. Certain amounts of plant residue (ungrazed herbage) must be maintained to protect the soil, ensure rainfall infiltration and sustain forage production. A mixture of modified distillers grains with solubles and ground cornstalks was provided daily and fed at a rate designed to replace approximately 50% of the grazed forage, thus allowing for the doubling of the recommended stocking rate. Stocking rate is defined as the concentration of grazing livestock on a given amount of land over a season, year or period of time. At a moderate stocking rate, only half the amount available for consumption (225 pounds per acre) can be used by livestock. You can find out more about pasture utilisation for cattle producers in the MLA More Beef from Pastures pasture utilisation module. Individual farm stocking … 1991. For some wildlife species, you cannot optimize cattle production and wildlife habitat at the same time. An animal unit is equivalent to an 1,110-pound dry cow at maintenance (Forage and Grazing Terminology Committee, 1991). 191-199. But Stalker says there are a few guidelines to follow if you plan to have your cattle graze cornstalks this fall or winter – starting with stocking rate. At a moderate stocking rate, only half the amount available for consumption (225 pounds per acre) can be used by livestock. Stocking rate refers to the actual number of stock per unit area at a particular time. In both studies animal performance declined when forage supplies fell below these threshold levels. Livestock stocking rate impacts not only a livestock operation and operation economics, but impacts wildlife habitat as well. If you already know your rotation frequency or are continuous grazing, proceed to Step 2. 0000001403 00000 n This means that stocking rates in the fall and winter should be about one to two acres per calf (600 lbs) and then two to three calves per acre in the spring. Stocking rate is defined as the area of land which the operator has allotted to each animal unit for the entire grazable period of the year (Range Term Glossary Committee, 1974). 1990. • Stocking Rate – what happens at farm level: • Feed cost and grass growth effects • Case Study of an expanding dairy farm • Outline of current situation • Assessing the options • Discussion and conclusions. If we have 100 acres and 100 yearling steers weighing 700 lbs., the stocking rate is one steer/acre or 700 lbs. He runs over 1,000 head of Angus cattle with 10,000 sheep on the property. More cattle usually means more production in total butsome loss of production per head. Stocking rate determines animal performance, financial return and the long-term condition of the range. Then if forage shortfalls and overgrazing occur, they are frequently blamed on drought. Stocking Rate . Range condition: sustained ranch productivity. 0000009244 00000 n Table 2 shows average stocking rate potential across various soil-climate regions of Alabama. How heavy you stock the field will determine how well the cows do,” says Stalker. cattle production, wildlife habitat). An explanation on how stocking rates effect livestock production, how stocking rates correlate to harvest efficiency and calculations behind stocking rates. The principle governing stocking rate decisions is to “take half and leave half.” This means that of the total forage produced during the year, half should remain ungrazed. The stocking rate chosen initially may not be the right one all year. Pressland, A. J. and T. W. G. Graham.
