Forage particle length is becoming an increasingly important issue in ruminant nutrition. Knowing the particle length, and understanding the factors which influence it, can promote better rumen health and milk production. This economical, easy-to-use Forage Particle Separator allows you to test your own forage or diet with immediate results on your as-fed feeds. By determining the different percentages of forage and feedstuff lengths, you can determine how much long feed material should be added to meet the needs of your dairy cows. This Forage Particle Separator will help you achieve the correct particle lengths needed to help meet the nutritional requirements of dairy animals. If minimum fiber levels are not obtained, cows often display one or more of the following metabolic disorders: reduced total dry matter digestibility, reduced milk fat percentage, displaced abomasum (DA), and an increase in the incidence of rumen parakeratosis. Reduced forage particle size has been known to decrease the time a cow spends chewing, which can cause decreased rumen pH. Smaller forage particles also spend less time in the rumen for microbial digestion, thereby decreasing digestibility. Diets that are too long can reduce intake and limit production. As determined from research data conducted by the Pennsylvania State University.
To use Nasco’s Forage Particle Separator, simply stack the four plastic separator boxes on top of each other. Next, place about three dry pints or 8 cups of forage in the top box. Shake the separator five times and then rotate the unit a quarter turn. Shake and rotate a total of eight times, then weigh the material remaining on each of the three screens and the bottom pan. Percentages of different particle lengths can then be calculated, and long forage can be added as needed to meet dietary requirements. The 0.16" (4 mm) sieve enables more accurate estimation of physically effective fiber by adding the amount on the top three sieves (0.75", 0.31", and 0.16" sieves).
Includes four forage boxes - one each with 0.75" (19 mm or 3/4") holes, 0.31" (8 mm or 5/16") holes, 0.16" (4 mm or 5/32") holes, and a solid bottom - and complete instructions for use.
