As legumes and grasses mature, the ratio of leaves to stems decreases, thus decreasing the nutritional value of the forage. For forage quantity to be adequate, there has to be sufficient quantity of the preferred plant species for the specific herbivore and sufficient forage of acceptable quality. Determining the proper supplementation program requires livestock managers to know the following: The decision to provide a supplement should be based on forage supply, protein content, and animal body condition. What else can be done? Protein is calculated from the amount of nitrogen contained in plants. Just like harvested forages, nutritional quality of pastures is related to the maturity of the forage when harvested. This generally occurs 50-55 days after cob silking and corresponds to a DM of 32-38% in the whole plant. Post was not sent - check your email addresses! The nutritional value of forage cover crops planted from mid-August through early September is high with total digestible nutrients (TDN) ranging from 70 to 80%. A dataset was created bearing degradability parameters of feeds from 40 studies. Varieties of kale differ markedly in winter hardiness, rate of establishment, stem development, and time required to reach maturity. Ruminants need the microorganisms to "unlock" the energy in forage, allowing them to harvest and make use of cellulose that is unavailable to non-ruminants. Increasing forage intake improves energy availability; therefore, correcting a protein deficiency is generally the first supplementation priority. Dairy producers strive to achieve legume forage with 20 to 23% crude protein (CP), 26 to 30% acid detergent fiber (ADF), 38 to 42% neutral detergent fiber (NDF), and a net energy for lactation (NE L) of 0.62 to 0.68 Mcal/lb. EMPYR Premier Forages are our top-of-the-line, carefully selected hybrids that consistently outperform and outproduce the others in their class in field and in feed. Energy values of forage are commonly reported as total digestible nutrients (TDN) or digestible energy (DE). Livestock contributes enormously in food and nutritional security apart from livelihood security to rural population all over the world. Abstract The nutritive value of a forage largely determines ruminant animal daily performance through the provision of digestible energy, crude protein (CP), minerals, and vitamins. With contributors including freelance writers, extension specialists and allied industry partners, the leading-edge content is balanced and promotes the best in the forage industry. The forage quality needed is based on the nutritive requirement of the livestock consuming the forage. Types of Protein Supplements. Table 2.2 at the end of this chapter shows the nutrient content of common feeds used as protein and energy supplements. Shrubs are generally considered good sources of phosphorus for general animal maintenance and gestation, even when mature. The available nutrients would also support about 1-1.5 lb/d gain on weaned calves if quantity was adequate,” said Karla Jenkins. Phosphorus content of plants can fluctuate depending on the soil status. Guidelines on feeding and processing methods, as well as comparative research data on animal performance, are included.

This may not represent the quality of the green forage that they’re eating because I took a sample with green, brown and seedheads mixed together.
