stocking rate for cattle

Posted By : / 0 0

The daily forage consumption of an animal unit is 17.64 pounds. Using an appropriate stocking rate for your forage resource is the first step in managing a sustainable pasture or range operation. Stocking rate determines animal performance, financial return and the long-term condition of the range. 0000037196 00000 n There are three approaches to this problem. A rancher wanting to leave 750 pounds per acre of threshold residue must subtract this quantity from the total forage supply to determine the forage available for consumption. 1991. Effect of long-term, year-long s. grazing at moderate and heavy rates of stocking on diet selection and forage intake dynamics. 22-25. Stocking rates refer to the number of stock, e.g. As profit levels decline, there is a greater chance the ranch will suffer a catastrophic loss. If this situation develops, the enterprise may not be able to survive crises caused by climate and market variability. “This was mainly driven by increased grass utilisation,” she added. 3.2 cows per hectare. 1990. Stocking rate refers to the actual number of animals grazed, which may not match forage production. 1989. So, eight ewes are one animal unit (meaning that eight ewes consume about 26 pounds of forage daily). Approaches to the restoration of rangelands – the Queensland experience. A cow can maintain her bodyw… High overhead and high family expenses, coupled with excessive stocking rates, will jeopardize the ranch and all its resources. For example, if an exclosure was established on July 1 and on August 1 (31 days later) the difference in forage supply between the grazed area and the exclosure equalled 75 pounds per acre, the disappearance would equal 2.4 pounds per day. 191-199. 0000010304 00000 n The number of animal units grazed determines the amount of forage that will be consumed each day and over the entire grazing period. The usual measure is dry sheep equivalents (DSE) per hectare (ha), however, this may also be expressed in terms of cattle per unit area, such as breeders (cattle) per ha or square kilometre. Stocking rate refers to the number of livestock on a paddock or a whole farm and is expressed as an indication of the number of a particular type of animal per unit area. “That’s the single most important consideration. Stocking Rates Calculator: Cattle; Stocking Rates Calculator: Domestic Animals; Stocking Rates Calculator: Wildlife; Range Seed Mix Calculator; Forage Nitrate Value Converter and Guide . pp. Grazing systems and stocking rates are used to influence livestock grazing behavior with the intent of improving livestock and vegetation performance. Many ranchers try to graze the maximum number of animals they believe possible under current and “hoped for” conditions. Stocking rate refers to the actual number of stock per unit area at a particular time. If you already know your rotation frequency or are continuous grazing, proceed to Step 2. Stocking rate is defined as the land area allocated to each grazing animal for a specific length of time. • The daily utilization rate for livestock. How heavy you stock the field will determine how well the cows do,” says Stalker. From flooding to drought, producers have to deal with all kinds of weather extremes, which often makes calculating stocking rates on available pastures and forages quite variable from year to year. 1974. From 1999 to 2002, a grazing trial was conducted on a commercial property in the coastal Burnett. At the high stocking rate, the volume of milk solids produced per cow dropped by 8-10%. How Do I Determine Actual Forage Production? Ranchers must select stocking rates with limited knowledge of future forage and market conditions. Convert for animal type you are using with Animal Unit Equivalents: Information: • The cow herd on the allotment has an average weight of 1400 lbs. 0000023512 00000 n 0000003011 00000 n Calculate proper stocking rate for cattle: Stocking Rate = Available forage Pounds eaten/month 5. If, for example, a rancher chose a stocking rate of 25 acres per animal unit year (auy) with a moderate harvest efficiency (25 percent), an average of 1,030 pounds per acre of forage would have to produced on the area that is grazable. Calculating stocking rate is relatively simple once the con-cept and terminology are understood. When I ask people what their stocking rates are for a year, I always hear “you can put one pair per eight acres.” I soon realized this statement is not accurate—there is not an identical pasture—anywhere. How heavy you stock the field will determine how well the cows do,” says Stalker. My land can support my 100 cows for 2.65 months (utilizable lbs forage ÷ lbs of feed consumed per month) 272,000 ÷ 102,720 = 2.65 months . When Should Stocking Rate Decisions be Made? Then, the planned stocking rate should be adjusted seasonally according to actual ranch conditions (Figure 4). You can find out more about pasture utilisation for cattle producers in the MLA More Beef from Pastures pasture utilisation module. Cattle may overgraze the most productive sites and preferred species before they use less preferred sites and species. In Heitschmidt, R. K. and J. W. Stuth (eds.). For grazed forages to remain productive, grazing use must be matched to the individual pasture’s carrying capacity. Stocking Rate Determination on Native Rangeland. High grazing pressure also increases labor requirements and competition between animal enterprises using the same range. Financial obligations often “force” a rancher into selecting a stocking rate too high for the forage supply available. How Much Forage Should be Ungrazed and How Much Can be Eaten? cattle production, wildlife habitat). High grazing pressure continued over several years causes the range to deteriorate and future productivity to be lost. Via the examples created in this article, the stocking rate example is (1,600 lb/acre x (50%)/100) / … Since the initial stocking rate is selected on the basis of projected forage production, the stocking rate has to be adjusted seasonally, according to actual forage production, to maintain a moderate stocking rate. This article uses three sets of data which explores this balance of stocking rates, productivity and profit. x�bbc`b``Ń3� ���ţ�1�x(�@� >� n endstream endobj 567 0 obj<>/ViewerPreferences<>/Metadata 29 0 R/Pages 28 0 R/StructTreeRoot 31 0 R/Type/Catalog>> endobj 568 0 obj<>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/Properties<>>>/ExtGState<>>>/Type/Page>> endobj 569 0 obj<> endobj 570 0 obj<> endobj 571 0 obj[/Indexed/DeviceCMYK 65 596 0 R] endobj 572 0 obj<> endobj 573 0 obj<>stream But they can use past records, experience and range surveys to make realistic projections of forage and market conditions (Figure 3). EXAMPLE FARM Beefy Acres is a cow/calf operation located in the Southeast. 0000030861 00000 n 0000001056 00000 n APSAT (Annual Planning Stock Adjustment Templates) uses pasture utilization ratings and actual versus expected growing conditions to project needed stocking rate adjustments (Kothmann and Hinnant, 1990). Denver, Colorado. The minimum residue levels needed to sustain production are 300 to 500, 750 to 1,000 and 1,200 to 1,500 pounds per acre (oven dry weight) of shortgrasses, midgrasses and tallgrasses, respectively. He explains that the corn grain is the most nutritious part of the plant, second is the husk and third in nutrient quality is the leaf. Stocking rates are often expressed in AUs/unit area (links to Animal Unit). The stocking rate chosen initially may not be the right one all year. Conner, J. R. 1991. Ungrazed herbage is an investment in future forage production. View more Farming and Ranching information ». A stocking rate refers to the number of animals per unit area for a given period of time. McGinty, Key to A. and L. D. White. Proper stocking rates occur between the threshold points for individual animal performance (point 1) and unit area performance (point 2). The code’s recommendations are not a complete list and they are not meant to replace expert advice, such as from a veterinary surgeon. Total Land Area ÷ [(# AUs) x (grazing season)] = Stocking Rate 100 ÷ (60 x 6) = 0.27 acres per AUM or 1.7 acres for the season. Generally, stocking rate is expressed as “animal units” for a given amount of land. Stocking Rate = Available Forage Pounds Eaten/Month Stocking Rate = 600,000 lbs/ac 800 lbs/month Stocking Rate = 750 animals/month 5. I rotate through them at a rate of once a week. 0000042553 00000 n 0000002265 00000 n 1988. A useful practice is to take photographs at several set locations on the ranch three or four times each year. Figure 5 shows the proper residue level (1,500 pounds per acre) for a tallgrass prairie site near Bowie, Texas. For an example, look at the listings in Table 1. Stocking rate is a management decision and one of the most important grazing management decisions a rancher or land manager makes. The rancher can conduct periodic range condition surveys to compare current species composition with known ratings in the Soil Conservation Service Technical Site Guides. Since an animal unit consumes 17.64 pounds of forage daily, in 1 year an animal unit requires 6,439 pounds of forage (365 x17.64). How does a rancher determine the quantity of forage he has and is likely to produce in coming months? At Grazing land management EDGE and Nutrition EDGE workshops many producers have described how they have improved profitability by using conservative stocking rates.. Terminology for grazing lands and grazing animals. Stocking rate. 0000003772 00000 n An explanation on how stocking rates effect livestock production, how stocking rates correlate to harvest efficiency and calculations behind stocking rates. Kothmann, M. M. and R. T. Hinnant. Researchers Study Modified Intensive-Early Stocking Rates. 0000030658 00000 n If livestock numbers arc based primarily on the average carrying capacity, the range will be overgrazed in dry years and undergrazed during wet years. Denial of the law of diminishing returns leads to ‘the fallacy of numbers’, that more cattle are always better than less. 0000013878 00000 n In a similar study in the eastern Rolling Plains of Texas, organic matter intake declined when forage supply was below 623 pounds per acre (Pinchak, et al., 1990). 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). 0000014836 00000 n A grazing area's stocking rate is different, but related to, its carrying capacity. Texas A&M Veterinary Medical Diagnostics Laboratory, Texas A&M College of Agrculture and Life Sciences. For example, if the total forage supply is 1,200 pounds per acre, only 450 pounds per acre is available for consumption ( 1,200-750 = 450). Calculating whole farm stocking rate on grass growth and forage requirements: Milking platform stocking rate. More cattle usually means more production in total butsome loss of production per head. Pressland, A. J. and T. W. G. Graham. Proper livestock distribution is one of the four principles of grazing management, which also includes stocking rate, season of use, and kind and class of animals. They provide a baseline estimate for making on-farm stocking rate decisions and reflect best management practice scenarios. Livestock grazing comparison is a method of comparing the numbers and density of livestock grazing in agriculture.Various units of measurement are used, usually based on the grazing equivalent of one adult cow, or in some areas on that of one sheep.Many different schemes exist, giving various values to the grazing effect of different types of animal. Forage utilization is assumed at 70 per cent of available forage. 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. OR: My stocking rate is 640 acres ÷ 385.2 AUMs = 1.66 acres per AUM. The formula for stocking rate is (Forage Yield (lb/acre) x (Utilization Rate (%)/100)) / AUM. The HG system was designed as a low cost pasture management system for a post EU milk quota scenario based on high levels of pasture utilisation and a low level of concentrate supplementation. 0000007970 00000 n This ratio of forage demand (forage intake needed by livestock) to forage supply is called grazing pressure. 0000042808 00000 n The minimum forage production required for different harvest efficiencies and stocking rates can be determined from Table 1. 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. By Tim Miller, NRCS Range Management Specialist Lawrence, Kansas. 0000003821 00000 n Australian Rangeland Journal, 11(2). x�b```b``-``c`�d`@ V�(G����l/����N��:e�N�Ȁ�UB��d?�c�n,EL�a3e:M�ImkIpWP��,���/;)s��ظ�60���aqqӌ��`���L3t�;(&���]H+�2ح��|/ֹ����²�� �����C���g|8�awa]#C�R���|���7��:l� �_1��A�b`PY9��D�Àx=@� B�RS endstream endobj 602 0 obj<>/Size 566/Type/XRef>>stream Both the number of animals grazed and the financial needs of the enterprise must be realistic in relation to potential forage production. Stocking Rate and Milk Output per cow, per Ha ‘Diminishing return once grass utilised is at max’ Stocking Rate. This page may take a few moments to load. But when proper amounts of forage are left ungrazed, rainfall infiltrates the soil and preferred plant species become better established and produce more forage than if grazed too closely. Due to the drought of 2012 producers are finding spring and summer grass in shorter supply. My land can support my 100 cows for 2.65 months (utilizable lbs forage ÷ lbs of feed consumed per month) 272,000 ÷ 102,720 = 2.65 months . With this surplus forage the rancher might bring in stocker animals, lease grazing or use prescribed burning to improve the range. day/ha per year; below this stocking rate, N leaching is usually low (less than 40 kgN/ha per year). About a cow/calf pair per 3 acres. 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 Glos- sary Committee, 1974). In one study in south Texas, when grazing pressure reduced forage supplies below about 750 pounds per acre, cattle consumed more browse and their intake of organic matter, digestible energy and crude protein rapidly declined (Hanson and Stuth, 1988). Livestock stocking rate impacts not only a livestock operation and operation economics, but impacts wildlife habitat as well. Stocking Rate . 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. How to Calculate Stocking Rate and Carrying Capacity Step 1: Estimate your pasture inventory Stocking rate on this farmlet was 4.5 LU/ha, while the majority of the winter feed requirements were imported from outside the grazing platform. The second treatment was double the recommended stocking rate at 7.63 animal unit month equivalents of forage demand per acre. of cattle (such as calves, breeding cattle and dairy). B-1646, Texas Agricultural Extension Service. pp. cattle production, wildlife habitat). 90-1. An animal unit is equivalent to an 1,110-pound dry cow at maintenance (Forage and Grazing Terminology Committee, 1991). Pinchak, W. E., S. K. Canon, R. K. Heitschmidt and L. Dowher. If we have 100 acres and 100 yearling steers weighing 700 lbs., the stocking rate is one steer/acre or 700 lbs. An AUM also is a common way of expressing stocking rates, such as “my pasture can support 125 AUM in an average year of growth.” The standard animal unit is a 1,000-pound cow with a 6-month-old or younger calf by her side. Breeding Unit (Cow & followers) A breeding unit is a cow and her offspring; that is dependant calves plus weaned cattle (followers) from the previous year, which are not yet ready for sale or use as breeders. Stocking rate calculator The stocking rate calculator is designed to determine the number of cattle or sheep you should put into a paddock based on its carrying capacity. Researchers Study Modified Intensive-Early Stocking Rates. The proper stocking rate for a pasture is affected by its topography, accessibility and range site characteristics, as well as by animal diet preference and grazing behavior. Briske, D. D. and R. K. Heitschmidt. One 80-pound ewe of a hair sheep breed equals .12 animal unit equivalent. Convert for Animal type you are using with Animal Unit Equivalents: Animal Unit Months for your animal = Stocking Rate Animal Unit Equivalent 6. If the remaining grazable forage (amount above desired residue) equalled 90 pounds per acre, then approximately 38 days of grazing would remain at the current stocking rate. 1989.
