For more detailed information on microbial inoculants please refer to other Team Forage Factsheets at:https://fyi.extension.wisc.edu/forage/fof/. Alfalfa is highly nutritious and a natural source of nitrogen. Factor in Feed Switches. Clostridial fermentation is more likely in hay silage if the forage moisture is greater than 65%. Alfalfa is a cool-season perennial commonly grown for feeding livestock or as a cover crop and soil conditioner. Avoid placing bags in locations with drainage issues. University of Wisconsin Extension, Team Forage, Focus on Forage Factsheet. The first costs to consider are labor, fuel and machinery. Saving Time and Fuel During Tillage Move the WebFeeding Directions. 2006. Alfalfa meal happens to be a versatile product that can be used in many ways in your organic garden. High-protein forage for all classes of horses. By harvesting early under good growing conditions, there is increased opportunity for an additional harvest that more than offsets the yield loss in the first harvest by harvesting early. A recommended minimum feed out rate of 12 inches per day was suggested. Muck and Holmes (2006) recommended a minimum silo bag removal rate of 12 inches per day. A small amount of canola oil is added to the chopped forage to control any potential dust. Ideal for horses with higher energy requirements such as performance horses and lactating mares. Most manufacturers offer special patch tapes that adhere tightly to plastic silo bgs and are weather and light resistant. Second and third harvests usually generally are shorter in height than the first harvest. This form needs Javascript to display, which your browser doesnt support. But waiting for increased yield when growth is good leads to poor-quality hay. Once harvested, the ground will need to be turned before next seasons planting takes place. WebPremium Chopped Alfalfa is manufactured by cutting Standlee forage into approximately 2-4 pieces. WebThese diets may be pelleted, ground and mixed, a mixture of ground forage (alfalfa) pellets and grain, and/or high-concentrate type. Therefore, under drought when growth is reduced, waiting for a more advanced maturity stage to allow increased production would be a wise management strategy. Keep children from playing on or around bags. Alfalfa pellets tend to be a bit drier This juice carries away a high concentration of soluble nutrients, representing a significant loss of valuable feed. WebIdeal For: All horses Underweight horses Performance horses Features: Alfalfa & grass hay Easy to mix with grains Consistent quality Helps Support: Hay shortages Poor hay quality In this case, increasing the packing pressure can help. Both of these harvests were under drought stress and plant height was only 10 to 12 inches in the third harvest. Unlike alfalfa, which has a deep root system, bluegrass is shallow rooted and will not compete well with the alfalfa if the topsoil is dry. Consider fencing the storage pad area to exclude domestic animals. Opportunities for Feedlot Pen Surface Improvements, Biologically Effective Grazing Management Reduces the Detrimental Effects from Drought Conditions on Grasslands, Drought Emergency Grazing Practices will have Costs Next Season, Fertilization of Extremely Grazed and Moderately Grazed Mixed-Grass Prairie with Slow Release Phosphorus and Urea, Grazing and Feeding Restrictions for Herbicides, Livestock Producers have Options for Dealing with Forage Shortage, Supplementing Cattle on Drought-affected Pastures and Ranges, Drought Related Livestock Poisoning by Weeds, Drought Increases Cyanobacterial Poisoning Risk to Livestock, Managing Odor Nuisance and Dust from Cattle Feedlots, Overwintered Cattle May Spread Weed Seeds, Testing Livestock Water Quality Critical During Drought, Extending Mobile-Mapping Beyond Field-Level Collection, NDSU Breeding Programs Using Unmanned Aerial Vehicle (UAV) and Robots. Orient bags north-south to promote melting of snow. In summary, plant height is the best indicator to use in determining when to harvest, especially in the first harvest, but also in later harvests. This fact sheet reviews bagged silage recommendations that help to maintain high quality forage. Use of the PEAQ stick will help you make the decision as to when to harvest. Chop alfalfa at 3/8-inch theoretical length Remember that these gasses are poisonous. Conversely, early irrigation The alfalfa plant has been cultivated for generations and growing alfalfa in your garden is easy. Alfalfa forage is low in sugar, moderately high in protein, high in calories For more information on feed out losses see Clark (2002). With bags, it is always important to close the bag off after each feeding. Homofermenters speed the fermentation process along while heterfermenters increase the shelf life during feed out. During this time, the forage varies in quality from day-to-day. The prime objective in determining when to harvest is to obtain prime hay in the bale. Alfalfas extensive root system nourishes both plants and soil. WebThe best method to estimate the RFV or RFQ in the first harvest is to utilize a PEAQ stick available for purchase from the Midwest Forage Association. Presently, landfilling is the recommended practice to dispose of plastic waste. Learn to adjust the packing machines braking pressure for varying moisture levels. Bag suppliers can provide a vent for this purpose. byMatthew Digman1 Bags need to be disposed of properly. Densities tended to decrease as particle size increased. Regrettably, there is no good way to predict when adding microbial inoculants will be effective. Optimal relative forage quality (RFQ) is achieved when alfalfa is cut at or near 170 RFQ based on scissor clip or PEAQ measurements. Plastic waste handling and disposal is a disadvantage of silo bags. 2 deep. However, the wet conditions could present some challenges with putting up the first cutting of alfalfa in a timely fashion and maintaining feed quality. 2006. Alfalfa has few pest problems, however, the alfalfa weevil can cause serious damage. The removal rate (inches removed from the silage face per day) influences loss during the feed out period. Plant height is the best indicator of when to take the first harvest (Table 1). Fields generally have varying maturity and height, especially in second and later harvests. Then you can either leave it out in the field, covered against the Here, well cover six management strategies for optimal If planting alfalfa for livestock, it will need to be harvested and cured prior to flowering (known as early-bloom stage). A similar effect was seen at the early flower stage. WebFeeding alfalfa hay on a windy day, where leaves are blown away results in an inadequate ration. The passage rate of alfalfa hay is approximately 36 hours vs. 70 hours for grass The preferred corn silage moisture range for bagged silage is 65-70%. When feeding hay pellets, I do a ratio of 2:1, cold water to pellets. To help quantify dry matter densities and losses in silage bags, a study was completed by agricultural engineers, Richard Muck and Brian Holmes (2006). Rapid silo filling is accomplished by having sufficient harvest, transport and silo filling equipment capacity and adequate labor to operate the equipment. Choose the Right Conditioner. Avoid these air pockets that interfere with proper fermentation. Prior to planting you should clean the area, work the soil, and remove any debris. pp.119- 120. Forage should be harvested at the correct degree of maturity to assure desired feed quality and proper sugar content for good fermentation. This is especially true for cash hay producers and dairy operations where prime hay means greater net returns for the alfalfa crop, but it can be important for beef cow producers also as a source of high-quality high-protein hay to be used in rations with other low-quality hays like mature grasses or slough hay. 6.https://fyi.extension.wisc.edu/forage/files/2014/01/ManageBunker.pdf, Focus on Forage Vol 9: No. This works for alfalfa, timothy, or orchard grass pellets. At Fargo, we have found that harvest should begin whenever the alfalfa reaches around 28 inches in height, regardless of the maturity stage, if prime hay in the bale is desired. Unlike other storage formats, bags or parts of bags can be labeled to show the location of specific feed inventories. To aid in forage removal and to minimize losses during feed out, place bags on an all-weather base such as macadam, asphalt or concrete. Since cows perform best when presented uniform quality forage, avoid feeding silage during the fermentation period. Hopefully, sometime in the near future, recyclers will be accepting this plastic waste and using it as a fuel or making it into other plastic products. An effective fermentation process is based upon a variety of factors including the types and numbers of bacteria found on the forage. Calculate the value of additional gain. Higher carbohydrate levels increases digestibility and animal acceptability, which should result in improved animal performance. Mailing address: NDSU Dept. You should begin to see sprouts within seven to ten days. What is the proper adjustment for bagging machines? 2023 Gardening Know How, Future US LLC, Full 7th Floor, 130 West 42nd Street, New York, NY 10036. Some producers have used a weighted chain, rope, or cable draped over the plastic near the feed out to limit air movement between the bag plastic and the silage. WebAfter the harvested alfalfa has dried out for two to three days, use a baler to wrap it up into rounds or squares. Only the amount of silage that will be fed in a short period should be removed or uncovered at one time. Excessive braking pressure causes over-filling that increases wear on the machine and tension on the plastic silage bag. What Weve Learned About Storing Feed in Bags. In addition, the stem nematode can infest and weaken stem buds. Follow the manufacturers recommendations for adding vents to the bag. Some provide stretch lines on the plastic bag as gauges to avoid over-filling. The dairy industry has increased use of corn silage Vol 3: No. Base your decision when to harvest on the valleys realizing that the short growth and more advanced maturity on the hilltops will not affect the quality extensively. We should have delayed the third harvest to obtain additional yield in this case. Dairy Freestall Housing and Equipment (MWPS-7). Deciding when to sell calves? At no time should more than three days worth of silage be exposed. Average dry matter loss across all bags was 14.6 percent (similar to a well managed bunker). Using GPS with GIS for Efficient Nutrient Placement, Choose the Right Nozzles for Field Sprayers, Cleanup of Oil and Fuel Spills in Agricultural Buildings Associated with Flooding, Low-stress Cattle Working Facitlities Video, Videos: Managing Stress on the Farm and Ranch, Harvesting Drought-Stressed Small Grains as Forage, Drought and Prevent Plating Crop Insurance, Potential for Drought Can Impact Prices and Marketing Plans, Livestock Water Quality Likely to be Impacted by Drought, Ranchers Should Consider Water Supply in Drought Plan, Select Best Annual Forages During Drought, Dealing With Flooding on Your Farm or Ranch, Ag Hub crops, crops-alfalfa When Should I Harvest Alfalfa. It makes a good drought-resistant plant too, as it doesnt like wet feet. A Wisconsin state standard is currently being developed which specifies how leachate and runoff from feed storage areas must be managed. Keeping bags away from other feed sources may also reduce damage caused by the occasional stray livestock animal. A correctly designed paved site provides an additional benefit in that it can be converted to bunker storage at some point in the future by adding walls. Vol 49(5): pp. Once you decide it is time to harvest, consideration should be given to time of day for harvest. Unfortunately, reducing fiber length also reduces available effective fiber for the animal. If the worst six bags were eliminated (47 total bags in study), the average loss dropped to 11.6 percent (similar to a well managed bunker). Any holes should immediately be sealed with tape to prevent oxygen from entering the silage mass. Frequently hilltops have less growth and are more advanced in maturity thanlower wetter areas of the field. Use a 0.5% per day predicted dry down rate from the sample date until 65-70% whole plant moisture is reached. Vol 4: No. Avoid methods that result in dislodging the face. Merely sprinkle the seeds evenly onto the soil and cover lightly with dirt. WebFEEDING TIPS: Weigh the amount of forage provided to each horse to ensure you are feeding the proper amount. Purdue University.https://www.agry.purdue.edu/ext/forages/rotational/articles/PDFs-articles/what-weve-learned-about.pdf. can be marked on the bag. Spotlight on Economics: Economic Lessons From Precision Agriculture in N.D. This green manure will then fertilize the soil as well as stimulate microbial activity, thus aerating it too. Seepage of forage juice can occur if forage is harvested at moisture contents above 70%. It becomes more difficult for these animals to digest once the plant matures. As with any farm operation, the value of tillage must be weighed against its cost. Again, maturity at harvest varies depending on the year and moisture level so it's best to use height to help decide when to harvest. Base your decision when to harvest on the valleys realizing that the short growth and more advanced maturity on the hilltops will not affect the quality extensively. North Dakota State University is distinctive as a student-focused, land-grant, research university. Air pockets can also be minimized by chopping at a shorter theoretical length of cut, 15% or less of the hay particles exceeding 1.5 inches. The alfalfa shoots will breakdown. 2002. dry matter/ft. Commonly available duct or masking tapes are not generally suitable for this purpose and will not provide a long-term seal. Hold the end of the plastic in place with some form of weight (sand, discarded silage, etc.) Table 1 also illustrates why harvest at early flower during the first harvest would be recommended when growth is less than 20 inches in height. Note that the relative feed value (RFV) (relative forage quality (RFQ) would produce a similar table) decreased from 220 to 149 as the plant height increased from 16 to 35 inches when all samples were taken at the early bud stage. or simply nail another board to the one used to wrap the end of the plastic bag. craig.saxe@wisc.edu. Also note that the loss in RFV was much less when the maturity stage increased from early bud to early flower within a given height. Place the sprouts into a clean sieve or a colander and run cold water over the sprouts for 1 minute. Cutting alfalfa to meet the needs of the livestock being fed should be the emphasis for this answer. Rinse the sprouts under cold water for 1 minute. This increases both plastic costs per ton of silage and the probability that more air will be entrapped in the silage mass. The higher the density of forage in a silo bag, the lower the amount of air infiltration as the bag is opened or if the bag is punctured. Feed separately in a feed bin or bucket, or mix with the feed ration to reduce rapid feed consumption (bolting). There are many ways to save fuel in tillage field operations: not tilling, choosing a minimum tillage operation over a heavier one, and ensuring your tractor and implement are set up properly. Whatever removal practice is used, the silage face should remain tight and smooth. 1277-1284. 7.https://fyi.extension.wisc.edu/forage/files/2014/01/FeedoutLossFOF.pdf, Coblentz, W. 2005. Sun-Cured Alfalfa, Cane Molasses, Vegetable Oil,Dried brewers yeast, Vitamin A Acetate, Vitamin D3, Vitamin E. Sun-Cured Alfalfa, Cane Molasses, Vegetable Oil, Dried brewers yeast, Vitamin A Acetate, Vitamin D3, Vitamin E. Premium Chopped Alfalfa Forage should be fed at a minimum of 1% to 1.5% of body weight per day if using as a complete hay replacement. These costs are estimated to range from $9 to $19 per acre, depending on the field operation and equipme. Since alfalfa roots quickly, it doesnt require deep plantingonly about a half inch (1 cm.) 2000. When growing alfalfa, choose an area with plenty of full sun. But what factor(s) should be used to determine when to harvest if these are not determining factors? Open bags cause billowing plastic that pumps air over the silage, increasing losses. Microbial Inoculants for Silage. Therefore, the optimum maturity stage at harvest will be more advanced than the first harvest. High What are the recommendations for filling silage bags? The growing season changes the optimum time to take the first cutting. WebOptimal relative forage quality (RFQ) is achieved when alfalfa is cut at or near 170 RFQ based on scissor clip or PEAQ measurements. Clark, J. Estimated RFV by plant height at two maturity stages. Rapid silo filling (within 3 days) increases the uniformity of forage moisture and quality in the silo, and reduces exposure of the forage to precipitation and air during filling. Locate bags away from woods and tree fence lines. Image by McKinneMike Alfalfa is a cool-season perennial commonly grown for feeding livestock or as a cover crop and soil conditioner. Wet silage is a poorer product and has a greater chance of freezing. The estimated RFV in Table 1 is for alfalfa standing in the field. If the worst six bags were eliminated (47 total bags in study), the average loss dropped to 11.6 percent. Bag Silo Densities and Losses. WebBecause alfalfa production spans several years, its important to start off with the most productive stands possible. Punctured bags allow air to enter, which can cause significant feed deterioration.
