The infl uence of CP content and ingredient complexity, feed form, and duration of feeding of the Phase I diets on growth performance and total tract apparent digestibility (TTAD) of energy and nutrients was studied in Iberian pigs weaned at 28 d of age. There were 12 dietary treatments with 2 type of feeds (high-quality, HQ; and low-quality, LQ), 2 feed forms (pellets vs. mash), and 3 duration...

Coconut coir dust and corn stover powder were taken as raw biomass materials for pellet production, using four uni-axial compression set-ups, to explore the influence of diameter inner hole cylinder, depth in , remained compaction on density. Sample pellets produced at force steady phase, maximum density coconut material is 1.53 g/cm3 (1530 kg/m3), 1.23 (1230 kg/m3) stalk are obtained, At same ...

The dynamic response of the rotor system in a ring die granulator is complex and difficult to solve when it operates under joint external, support gear mesh forces. To this problem, finite element method extrusion theory was applied study develop coupling model for hollow overhung with external load excitation. A Newmark-β numerical integration used multiple excitation results included time-dom...

Particles of beech wood were treated with hot water at the temperature 150 oC, during 60 min, prior to pelleting process. The applied pretreatment affected chemical composition and heating value particles. Two groups pellets, designated as PT 10 20, produced from particles, moisture content particles being 10.5 20.5 %, respectively. Pellets nontreated (PNT) served controls assess effects on pel...

In order to study the effect of turmeric rhizome powder (TU) and enzyme in some blood parameters of laying hens, an in vivo study was conducted. In a 5 * 2 completely randomized block design with factorial arrangement, 5 levels of TU (0.0, 0.05, 0.10, 0.15, and 0.20 %) and 2 levels of enzyme (0.0, and 0.05%) with 4 blocks (replicate) , 480, 100-week old laying hens for 4 weeks fed wheat-soybean...

I. The effects of processing cereals on aspects of rumen metabolism, physiology and pathology were investigated in five experiments with lambs. Three experiments studied the effects of diets containing loose whole, pelleted whole or pelleted rolled barley on rumen volatile fatty acid ratios, rumen pH and digestibility. In a 4th experiment the effects, on the same measurements, of pelleting whol...
