Effects of barley grain particle size on dairy cow performance

Particle Size Effects on Hydro-Cyclone Performance

The hydrocyclone has a very important roll in industrial separation. The consideration of its behavior is very important for design. In this investigation, behavior of water flow and particles trajectory inside a hydrocyclone has been considered by means of numerical and experimental methods, and results have been compared together. To have a numerical simulation, a CFD software was used, and f...

Effects of Barley Grain Particle Size on Ruminal Fermentation and Carcass Characteristics of Male Lambs Fed High Urea Diet

Two experiments were conducted to evaluate effects of barley grains particle size on ruminal pH and ammonia concentration of rams (experiment 1) and carcass characteristics (experiment 2) of male lambs fed high urea diet. Treatments in two experiments were (1: basal diet + whole barley grains, 2: basal diet + ground barley grains with a 5 mm screen, 3: basal diet + ground barley grains with a 3...

effect of substitution barley grain with dried citrus pulp on performance of holstein dairy cow

in order to determine the effects of substitution of barley grain with dried citrus pulp (dcp) on eight lactating holstein cows with average body weight of 550 ± 50 kg and 75 ± 15 days in milk were allocated to 4 dietary treatments, which were diet; the control with 0% dried citrus pulp (dcp) and 15% barley grain, diet 2, 3 and 4 containing 5, 10 and 15% dcp and 10, 5 and 0% barley grain respec...

effect of supplemental dietary fat and processed barley grain on performance of lactating dairy cow

the effect of barley grain processing and source of supplemental fat on performance of lactating dairy cows were studied in a replicated 4 × 4 latin square design with 21-d periods and a 2 × 2 factorial arrangement. eight holstein cows with mean body weight (bw) of 572 ± 71 kg and 45 ± 10 days in milk were allocated to 4 dietary treatments including 1) ground barley with cottonseed 2) pelleted ...
