Cover crops can provide many benefits for the soil in crop productions systems. Benefits can include conserving soil and water as well as improving the soil. Reduced Erosion An obvious effect of growing cover crops is covering the soil surface, which can significantly reduce the potential for wind and water erosion. This is particularly true […]
Interseeding (Drilling or broadcasting early season into standing crop) Establishing cover crops after corn and soybeans is a challenge in Wisconsin due to the minimal amount of growing season left after harvest. Interseeding a cover crop during the vegetative growth of these crops provides Wisconsin farmers a cover crop establishment method earlier in the season. […]
Wisconsin’s short growing season doesn’t provide a lot of time for growing cover crops. However, the early harvest of winter wheat allows an excellent window for cover crops to grow, protect the soil and provide other benefits. Cover crop recommendations typically change depending on where you are in Wisconsin but because of the early harvest […]
Farmers have been making silage pile for years, but some methods have allowed huge storage losses. Typically, a pile is constructed by unloading silage into an elevator and piling up the silage, much as a quarry piles sand or gravel. This piling method misses the most important step – PACKING.
“Update on starch utilization by dairy cows” was presented by Randy Shaver, University of Wisconsin. Two-to fourfold increases in corn prices in recent years over historical trends have prompted many questions about the utilization of starch by dairy cows.
Quality of corn silage is determined by energy content and intake potential as well as content of protein and minerals. Methods used to evaluate corn silage quality include chemical methods such as fiber analysis, biological methods such as fermentation with ruminal microbes, and instrumental methods such as near-infrared reflectance spectroscopy (NIRS) which predicts nutrients rather than measuring them directly.
There continues to be a lot of interest in corn silage harvested with a self-propelled forage harvester (SPFH) equipped with an aftermarket processor having cross-grooved processing rolls set for 2- to 3-mm roll gap and greater roll speed differential than has typically been used (32% versus 21%). Also, the developer of this processor recommends that […]
Increasing starch or neutral detergent fiber (NDF) digestibility in whole-plant corn silage (WPCS) may increase lactation performance by dairy cows or reduce purchased feed costs for dairy farmers.
Hay producers working in humid environments are well-acquainted with the consequences of baling moist hays, which include heating, molding, losses of dry matter (DM) and nutritive value, and the possibility of spontaneous combustion.
If we understand and use the biology and physics of forage drying properly, not only does the hay dry faster and have less chance of being rained on, but the total digestible nutrients (TDN) of the harvested forage are higher
Pricing corn silage is a difficult decision because it often comes at a time when emotions between sellers and buyers are high. The seller has the opportunity to sell a corn field for either silage or grain and incorporate the fertilizer value of the stover back into the field. The buyer has the opportunity to buy a corn field for silage or buy grain from the market and purchase low quality straw (wheat or corn stover aftermath) to formulate rations.
Nitrate poisoning is a condition that may affect ruminants consuming certain forages or water that contains an excessive amount of nitrate. Horses are much less sensitive to nitrate toxicity since they are hindgut ferments and do not have a rumen.
