this study investigated the inhibitory effects of bacillus licheniformis on g1 and g2 aflatoxins in culture media and kilka fish meal. two concentrations of aflatoxins (8 and 12 ppb for g1 and g2) and (2 and 4 ml from aflatoxins standard per 50g of fish meal) were used in culture media and kilka fish meal respectively. the doses of bacillus were 3 and 4% for this experiment. changes of aflatoxi...

Fly larvae may provide an effective method to mitigate two large and growing global concerns: the use of fish meal derived from capture fisheries in aquaculture diets and manure management in livestock and poultry facilities. A 9-wk feed trial was conducted to determine whether fly larvae could be used as a partial fish meal and fish oil replacement in rainbow trout, Oncorhynchus mykiss, diets....

Weanling pigs (total of 560) were used in two experiments to determine the effects of poultry meal in nursery diets on pig performance. In Exp. 1,210 barrows and gilts (initially 7.4 kg and 21 +/- 2 d of age) were fed one of five diets, which included a control diet with no specialty protein products or (as-fed basis) the control with 2.5 or 5.0% fish meal, or 2.9 or 5.9% poultry meal (11.8% as...

Precision feeding aims to provide the correct amount of feed farmed animals for optimal growth and performance avoid waste. However, knowledge underlying meal-to-meal variability in voluntary intake species is still limited. This study examined relationship between meals, deprivation time (pellets) consumed by Atlantic salmon post smolts. The data was collected from individual fish handfed sati...

Meta-analysis was applied to quantify the effect of replacement of fish meal by soyabean products in diets on fish growth. Measurement of growth in different units among studies required the use of a standardised effect size (Hedges' d). From a total of ninety-nine studies concentrating on fish meal replacement by defatted soyabean meal, 53 % were eliminated due to, among others, absence of a f...
