In order to clarify the influence of feed rate on a hydrocyclone flow field, numerical simulation was employed model pressure velocity air column, turbulent kinetic energy, and split ratio. The results revealed that static pressure, tangential velocity, radial increased with an increase in rate. When at inlet increases from 1 m/s 5 m/s, 5.49 kPa 182.78 kPa, 1.97 11.16 0.20 1.16 demonstrating hi...

The article presents the results of experimental studies process extracting excess liquid from a water-saturated hide. experiments were conducted in two options: using rigid base plate and cermet for feed mechanism roller machine. In study, samples wet hide on plates pulled between rotating squeezing rollers conveyor chains. Mathematical dependences amount removed its rate pressure obtained spe...

The effects of feeding level on body weight (BW), lifetime growth rate, backfat thickness (BF), fatness (BF/BW) and ovulation rate at first (puberty) and second estrus were examined in 145 gilts. From 47.2 kg until puberty, gilts were fed 2.0 kg/d (L) or had ad libitum access to feed (H). From puberty to second estrus, the feed allowance of one-half of the L gilts was increased to 2.8 kg/d. Flu...

Skolpap, W., Scharer, J.M., Douglas, P.L. and Moo-Young, M. Optimal feed rate profiles for fed-batch culture in penicillin production Songklanakarin J. Sci. Technol., 2005, 27(5) : 1057-1064 The fed-batch optimization of penicillin productivity was applied as an example of optimization algorithm verification. The objective function of this problem was to optimize penicillin productivity by dete...

Net feed conversion efficiency (NFCE) describes whether an animal eats more or less feed than expected for its size and growth rate. Early results from the Trangie NFCE Project, and from the Beef CRC, show that considerable variation in NFCE exists within each of the British breeds tested and is moderately heritable. Estimates of heritability for average daily gain, 365-day weight, feed intake,...

Five groups of broiler chickens were raised on feed containing varying substitutions of single cell protein from preprocessed waste activated sludge (pWAS) in varying compositions of 0:100, 25:75, 50:50, 75:25, and 100:0 pWAS: fishmeal by mass. Forty chickens per batch were evaluated for growth rate, mortality rate, and feed conversion efficiency (ηє). The initial mass gain rate, mortality rate...

This experiment was conducted, during a seven-week period to investigate, the effects of using various levels of garlic cloves and turmeric rhizome powders, on laying hens’ performance, egg quality characteristics and cholesterol content in yolk. Two hundred and sixteen, 27-weeks old Novogen white laying hens were assigned randomly into nine treatments with eight replicates of three birds each....
