Two experiments were conducted to determine the NE content of dry extruded-expelled soybean (DESBM) and the effect of a multienzyme carbohydrase (MC) mixture on the NE content of DESBM and to determine the effect of diet design on NE values in growing pigs using indirect calorimetry (IC). In Exp. 1, 24 barrows (19.6 ± 0.51 kg BW) were allotted in a completely randomized design to 4 dietary trea...

different compositions of liquid media were used for their efficacy in the production of beta-galactosidase by aspergillus oryzae in submerged fermentation. enzyme production was improved by switching from lactose-based media to soybean meal- and wheat bran-based media. further improvement was made when the soybean meal medium was supplemented with sodium nitrate and magnesium sulfate. results ...

—Taurine has been demonstrated to be conditionally indispensable for several carnivorous fish species. Current trends in trout production include decreasing levels of fish-meal content in feeds, along with faster growing strains of fish. Taurine may be a limiting nutrient in support of elevated planes of growth for rainbow trout. A 9-wk feeding trial was conducted using a factorial treatment de...

Naturally fauna-free crossbred rams approximately 5 mo old, 49.3 +/- 1.88 kg live weight, were allotted to four groups. Two groups remained fauna-free, whereas the other two groups were faunated. A diet based on corn silage-soybean meal containing either a low or a high Cu concentration (7 or 15 micrograms/g dry matter) was fed ad libitum to the two groups for 197 d. The rams were killed at the...

A total of 786 pigs (PIC TR4 × (Fast LW PIC L02); initially 213.2 lb ± 2.37 lb) were used to evaluate the effects increasing soybean meal (SBM) in corn-wheat middsbased diets on growth performance late finishing pigs. Pens blocked by BW and randomly assigned 1 5 treatments with 9 replications per treatment. Experimental corn-based 30% wheat midds. Soybean levels increased from 0 16% replacing a...

The use of various protein sources (industry by-products, proteaginous) in poultry diets requires a greater understanding of protein digestion mechanisms. The aim of this study was to characterize the molecular actors required for protein digestion in broilers fed 4 different diets containing soybean meal, rapeseed meal, pea, or corn distiller's dried grain with solubles as the only protein sou...

Two experiments were conducted to evaluate the effects of 1) two grain mixtures and 2) various carbohydrate sources and levels fed to weanling pigs during the initial 2 wk postweaning. A total of 720 crossbred pigs were weaned at 23 +/- 2 d of age at an average BW of 5.8 kg. In Exp. 1, a 2 x 3 factorial experiment in a randomized complete block design was conducted in 12 replicates. Treatment d...

This study was conducted to investigate the effects of partial replacement of dietary fish meal with soybean meal (SBM) on some blood and serum parameters of Beluga (Huso huso) juveniles. Three isonitrogenic and isoenergetic diets, as SBM1 (Soybean meal protein (SBP): Fishmeal Protein (FP) =1:3), SBM2 (SBP: FP = 2: 3) and SBM3 (SBP: FP =1: 1) were fed to triplicate groups of fish. After 8 weeks...

poultry requirments for vitamins and minerals are met from two sources feed ingredients and premixes.in practical poultry nutrition, the role of feed ingredients is over looked. this experiment was conducted to evaluate the effects of the time of vitamin and mineral premixes withdrawal on growth and economic performance of broilers. four hundred and fifty, one day-old male broiler chickens (ros...
