This study was conducted to determine in vitro crude protein degradation (IVDP) parameters and effective crude protein degradability (EPD) of various feeds using the modified in vitro gas production (GP) technique. Feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. Rumen fluid was collected before the morning feeding from four rumen fistulated lam...

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...

The aim of this study was to determine the effect of fish meal and mineral-vitamin premix, supplementing organic diets, on the performance of pigs and some meat and blood characteristics. The experiment was conducted on an organic pig fattening farm. The study involved 120 pigs with an approximate 25 kg body weight. Animals were divided into 3 groups, kept in pens, 10 animals each. Group I (con...

A 60-day feeding trial was conducted to evaluate the potential of using poultry by-product meal (PBM) as a partial replacement for fish meal (FM) in the diets for juvenile sobaity. Six iso-nitrogenous and iso-lipidic diets were formulated to contain graded levels of PBM, at 0 (as control diet), 15, 25, 35, 45, and 55% of FM replacement. Each diet was fed to groups of 20 juvenile sobaity in trip...

Four hundred and eighty five rainbow trout (76 ± 6.44 g mean weight) were acclimated to laboratory conditions and then randomly divided into four groups of tanks in triplicate. The first group (Group 1) was fed on a commercial diet (control) without Bacillus subtilis supplementation. The second, third and fourth groups (Group 2, Group 3 and Group 4, respectively) were given a diet supplemented ...

In 2 experiments, 602 pigs were used to evaluate the effects of fish meal, fermented soybean meal, or dried porcine solubles on phase 2 nursery pig performance. In Exp. 1, nursery pigs (n = 252; PIC TR4 x 1050; 6.8 kg initial BW and 7 d after weaning) were fed: 1) a control diet containing no specialty protein sources and the control diet with 2) 5% fish meal, 3) 3.5% dried porcine solubles, 4)...
