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: Kill (plow or spray) the alfalfa stand now and plant a full-season corn hybrid, control perennial grasses and broadleaves with a post-emergence […]
Attaining a high silage density is important for two primary reasons. Most importantly, density and dry matter content determine the porosity of the silage.
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.
Establishment of dense vigorous stands of alfalfa is essential for long-term profitability, but establishment can be challenging because seedling alfalfa is vulnerable to competition from annual weeds and wind and water erosion. Roundup Ready Alfalfa was re-introduced last year as a new tool available to farmers growing high-quality alfalfa. While not for everyone, it will be useful for many alfalfa growers.
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.
