The Master Forage Probe from Dairy One can help you gather valuable information needed to evaluate and improve silage management. Available exclusively from the Dairy One Forage Lab, the probe is designed to measure silage density, as well as obtain representative core samples from the face of bunk silos, bagged silage, and large round and square baled hay.

Corn and hay crop silages are valuable commodities on dairy farms. Measuring silage density is a good way to determine how well the silage is packed. A good fermentation relies on proper packing to exclude oxygen. Inadequate packing in bunk silos, trenches, piles and ag bags can lead to nutrient loss and spoilage, thereby lowering feeding value and potential milk production.

Density Calculators

Instructions for Determining Density
Follow Master Forage Probe sampling instructions

1. Select a sampling site and using your Master Forage Probe, obtain a core sample of at least 6 inches (15 cm) and not greater than 10 inches (25 cm). Withdraw the probe and insert plunger into the hole. Measure and record the depth of the hole as the Core Depth. Enter the Core Depthin inches or cm into the calculator.
2. Weigh a plastic bag or bucket large enough to hold the entire contents of the probe and record weight (container weight). Empty the entire contents of the probe into the container, weigh and record (combined weight). Subtract the container weight from the combined weight to determine the Core Weight. Enter the Core Weight in grams into the calculator.
3. Determine the dry matter of the core sample using a Koster Tester,  Microwave Oven or Laboratory value. Enter the Dry Matter. ClickCalculate to display the density.
4. Using the above information, your density will automatically be calculated in lbs./cu. ft. on an As Sampled and Dry Matter Basis.
5. If performing a multiple site evaluation, repeat the above steps for each site. The calculator will determine the individual density for up to three sites and compute the average.

Note: the density calculator is calibrated to work specifically with the Master Forage Probe. Entering depths and weights obtained using another sampling device will result in erroneous density values.

乳制品的主饲料探针可以帮助您收集评估和改进青贮饲料管理所需的有价值的信息。该探针专门用于乳制品饲料实验室，该探针设计用于测量青贮饲料密度，并从面包堆垛，袋装青贮饲料和大型圆形和平方ed草获得代表性的核心样品。

玉米和干草作物青贮饲料是奶牛场的宝贵商品。测量青贮饲料密度是确定青贮饲料的良好方法。良好的发酵依赖于适当的包装以排除氧气。双层仓库，沟渠，堆垛和农用袋子的包装不足会导致营养物质的损失和腐败，从而降低了饲料价值和潜在的牛奶生产。

密度计算器

确定密度的说明
遵循主饲料探针采样说明

1. 选择采样站点并使用您的Master Forage Probe，获取至少6英寸（15厘米）且不大于10英寸（25厘米）的核心样品。拔出探头并将柱塞插入孔中。测量和记录孔的深度为核心深度。在计算器中输入英寸或厘米的核心深度。
2. 称重一个足够大的塑料袋或桶，以容纳探头的全部内容物并记录重量（容器重量）。将探头的整个内容物清空到容器中，称重并记录（组合重量）。从组合重量中减去容器重量以确定核心重量。输入芯重量以克到计算器。
3. 使用Koster Tester，微波炉或实验室值确定核心样品的干物质。进入干物质。单击计算以显示密度。
4. 使用上述信息，您的密度将自动计算在lbs./cu。以取样和干物质为基础。
5. 如果执行多站点评估，请对每个站点重复上述步骤。计算器将确定最多三个站点的个人密度，并计算平均值。

注意：密度计算器被校准以与主饲料探针专门工作。输入使用其他采样设备获得的深度和重量将导致错误的浓度值。
