Only the intake depends <strong>on the total amount of feed<\/strong>, the other parameters give a density.<\/li>\n \t<li><strong>VEM<\/strong>[\/kg DS] The Feed Unit Milk is a measure of total <strong>energy requirements<\/strong> (milk production, growth, gestation and maintenance). Like the other parameters below, it is evaluated per kilogram of dry matter, i.e., as a density.<\/li>\n \t<li><strong>FOS<\/strong> [g\/kg DS] Fermentable Organic Matter is a measure of <strong>pens energy<\/strong>. It is the amount of organic matter available in the rumen for rumen microbes.<\/li>\n \t<li><strong>DVE<\/strong> [g\/kg DS] Intestinal Digestible Protein is the <strong>protein<\/strong> that is digested in the <strong>thin intestine<\/strong>. It is important for <strong>milk protein<\/strong> and it pushes for <strong>milk production<\/strong>. It comes from two sources: one is protein formed in the rumen (microbial protein), and the other is plant protein that passes untouched from the rumen to the intestine (resistant protein).<\/li>\n \t<li><strong>OEB<\/strong> [g\/kg DS] The Unstable Protein Balance is a <strong>balance<\/strong> between the available <strong>protein<\/strong> on the one hand and the available <strong>energy<\/strong> for the <strong>pens microbe<\/strong> on the other. In theory it should be zero, in practice the value may be higher to push for <strong>milk production<\/strong>.

The rate of digestion of cell walls, starch or protein can be greatly affected by the moisture of the ration.<\/li>\n \t<li><strong>RE<\/strong> [g\/kg DS] Share <strong>Rough Protein<\/strong>. Proteins can vary considerably in the rate at which they are broken down in the rumen. Rapidly degradable is the <strong>unresistant<\/strong> portion, slowly degradable is the <strong>resistant<\/strong> portion. RE supply is important for <strong>milk production<\/strong> and <strong>milk protein<\/strong> formation, provided it is combined with sufficient energy.<\/li>\n \t<li><strong>RC<\/strong>[\/kg DS] The <strong>Red Cellulose<\/strong> is a component of the <strong>cell wall<\/strong> carbohydrates. Depending on the shedding of the plant, it can be highly or less <strong>digestible<\/strong>. The less digestible, the more <strong>structural in the rumen<\/strong>. Slowly digestible crude fiber results via acetic acid formation in <strong>milk fat<\/strong>.<\/li>\n \t<li><strong>NDF<\/strong> [g\/kg DS] <strong>Neutral Detergent Fibre<\/strong> represents the total weight of <strong>cell walls<\/strong>.  A cell wall is composed of a middle lamella (contains mainly pectin), a primary cell wall (contains mainly cellulose and hemicellulose) and possibly a secondary cell wall (contains mainly lignin (wood dust) and possibly cutin (cork dust)). Pectins are largely converted to propionic acid to form glucogenic <strong>energy <\/strong>while cellulose and hemicellulose are largely converted to acetic acid to form <strong>milk fat<\/strong>.&lt;\/li\n \t<li><strong>ADL<\/strong> [g\/kg DS] The <strong>Acid Detergent Lignin<\/strong> is the part of the plant that is completely <strong>not digestible<\/strong>. These lignins disappear again via manure. They do have a value, in that lignins provide the <strong>feel prick<\/strong> in the ration and, along with cellulose and hemicellulose, give rise to <strong>required activity<\/strong>.<\/li>\n \t<li><strong>ADL\/NDF<\/strong> is a ratio we calculate to estimate how good the <strong>digestibility of the cell walls<\/strong> are. A low ADL\/NDF ratio corresponds to high NDF digestibility while a high ratio indicates low digestibility.<\/li>\n \t<li><strong>SET<\/strong> [g\/kg DS] <strong>Starch<\/strong> are part of the <strong>cellular content<\/strong> carbohydrates. These are easier to digest than the RC. <strong>Resistant<\/strong> starch passes through the rumen to the small intestine and can be used directly as an energy source. <strong>Unresistant<\/strong> starch can be used as an energy source for rumen microbes (FOS) and\/or can be converted to propionic acid in the rumen and then used as an energy source through the liver. Excess of unstable starch can lead to <strong>pens acidification<\/strong> via lactic acid formation.<\/li>\n \t<li><strong>BZET<\/strong> [g\/kg DS] <strong>Resistant Starch<\/strong> is the fraction of starch that is <strong>unavailable in the rumen<\/strong> and that becomes digestible in the small intestine only after it is enzymatically broken down there into glucose. It thus makes a greater contribution to glucose supply than unstable starch. In the case of <strong>too high resistant starch<\/strong>, excess starch enters the <strong>thick intestine<\/strong>. In the colon, the starch provides less energy for the cow and can also lead to the formation of unwanted bacteria, such as E. Coli.<\/li>\n \t<li><strong>SUI<\/strong> [g\/kg DS] <strong>Sugars<\/strong> are part of the <strong>cellular content<\/strong> carbohydrates. They are highly <strong>fast digestible<\/strong> in the <strong>pens<\/strong> (FOS). A limited amount of sugar possibly results in additional <strong>milk fat<\/strong> via beta-hydroxybutyric acid formation, however, excess can lead to <strong>pens acidification<\/strong> via lactic acid formation.<\/li>\n \t<li><strong>FAT<\/strong> [g\/kg DS] Fats (often also abbreviated as RV), are very <strong>energy-rich<\/strong>. Resistant fats pass through the rumen. For non-resistant fats, the allowable amount is limited so as not to interfere with proper <strong>pen function<\/strong>.<\/li>\n<\/ul><\/span>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b905cbc elementor-widget elementor-widget-heading\" data-id=\"b905cbc\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Techno-economic key figures<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1983898 elementor-widget elementor-widget-text-editor\" data-id=\"1983898\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<span class=\"translation-block\">In addition to pure feed values, it is also important to evaluate <strong>technical<\/strong> and <strong>economic key figures<\/strong> of a ration.
