What is forage testing?
Forage testing provides the nutritional value of pasture, hay, or silage. It is important to know the quality and nutrient content of feed to calculate an efficient feed ration and mineral supplementation program.
What are three important factors for forage quality?
Six major factors affecting forage quality (not yield), ranked by their impact on forage quality, include: maturity, crop species, harvest and storage, environment, soil fertility, and variety. The relative importance of these factors, and some exceptions to the ranking, are described as follows.
What determines forage quality?
Determinants of Forage Quality Forage fiber content is the primary detractor to high intake and nutrient availability. Relative to assessing forage quality, fiber tests are our single best method, though additional tests for protein and moisture can help to further characterize the forage.
How do you improve forage quality?
By offering livestock mixed grazing pastures or blending feeds, nutritional quality can be enhanced. For example, alfalfa is the highest-yielding perennial forage legume and produces more protein per unit area than other forage legumes and so can be grown alone or in combination with a range of different grass species.
Why does forage quality decrease with maturity?
Maturity at harvest Forage leaves contain considerably more protein and less fiber than the stems, so as forage matures and the stem becomes more prevalent and fibrous, quality decreases and the plant becomes less digestible.
How is ADF and NDF calculated?
The ADF percentage is measured by boiling forage in an acid detergent solution, then measuring the residue remaining. In the same way, NDF is measured by boiling the forage in a neutral detergent solution, then measuring the insoluble residue.
How is alfalfa tested?
Laboratory evaluation of alfalfa and other hay quality may be performed by chemical analysis or by near infrared reflectance spectroscopy (NIRS). Once the results are obtained from the laboratory, estimation of actual quality or feeding value must be determined.
What is pasture and forage?
Meaning of Pasture and Forage Crops A pasture is an area of land on which grasses and legumes (forages) grow for animals to graze. Forage crops are plants cultivated for their vegetative portions in a pasture and are used either in fresh or preserved for feeding livestock such as cattle, sheep and goat.
What is difference between forage and fodder?
Fodder refers mostly the crops which are harvested and used for stall feeding. Forage may be defined as the vegetative matter, fresh or preserved, utilised as feed for animals. Forage crops include grasses, legumes, crucifers and other crops cultivated and used in the form of hay, pasture, fodder and silage.
Why is forage quality important?
As a forage matures, its digestibility, rate of digestion and CP content decline, causing the cow to derive fewer nutrients from the forage, lowering the quality. A decline in the quality of forage has an impact on the amount of other feedstuffs that the animal is able to consume.
