We have paid little attention to Pure Live Seed (PLS) in the Midwest because we have generally had high quality seed (greater than 90% germ and 98% purity). But the short forage seed supply has caused some low quality seed to come on the market. To avoid being caught paying market price for low quality […]
When haymaking conditions are poor hay may be rained on or left lying in the field for prolonged time periods due to cool and humid conditions which reduced drying rates. The long drying periods with high humidity allow field growth of mold on the hay.
Difficult alfalfa harvesting conditions sometimes result in farmers being off schedule for late summer harvesting alfalfa. This raises the question of best cutting management of alfalfa harvest as the end of summer approaches. If we want good winter survival and rapid greenup for good yield next year, alfalfa must either: This has resulted in the […]
The plant density that maximizes corn grain and silage yield has been increasing through time. The economic optimum plant density is a function of corn yield and quality responses, seed cost, and grain or silage price. The economic plant density is lower than the plant density that maximizes yield.
Introduction It’s early May, you’re looking at a rather marginal alfalfa stand, the haylage silo is nearly empty, and you generally use some corn silage in the dairy ration. Here are the options: What are the advantages and disadvantages of each option? With Option 1, you give-up all alfalfa production on the field for the current […]
wheat seed not collected in the combine becomes a weed and impacts alfalfa establishment and productivity, especially in no-till and reduced-till fields. Previous research in Wisconsin has shown that volunteer wheat can reduce alfalfa density by up to 50%, resulting in shorter alfalfa stand life and reduced forage quality the following spring.
“Cut alfalfa at late bud for optimum quality.” We’ve heard this statement, or a similar one, many times over the past 10 to 15 years. Although forage quality is strongly correlated to morphological stage (for example, late-bud or first flower), many years of monitoring the forage quality of a standing crop has taught us that environment plays an important role in what the actual forage quality might be at a specific stage of maturity.
Alfalfa may start growing in the spring while some freezing nights are still occurring. This has caused many management questions among farmers.
Undersander et al. (1993) developed a method for estimating milk per ton of forage dry matter (DM) as an index of forage quality of alfalfa and grasses. The milk per ton index of Undersander et al. (1993) is based on energy content of the forage predicted from acid detergent fiber (ADF) content and DM intake potential of the forage predicted from neutral detergent fiber (NDF) content.
Attaining a high silage density is important for two primary reasons. Most importantly, density and dry matter content determine the porosity of the silage.
As interest grows in adding grasses to dairy rations (to add digestible fiber and improve cow performance and health), many dairy producers find themselves learning about a feedstuff they haven’t grown or used in many years. This Fact Sheet will explore some reasons for feeding grasses, discuss some of the agronomic considerations producers need to think about when growing grasses for […]
Relative Feed Value has been widely used for ranking forage for sale, inventorying and allocating forage lots to animal groups according to their quality needs, as well as determining when to harvest.
