Concerns have been raised about the presence of the bioaccumulating pesticide toxaphene in the tissues of Great Lakes fish. Toxaphene, banned in the U.S. since 1990, is an environmentally persistent chlorinated hydrocarbon mixture of over 670 chemical congeners. Current fish consumption advisories issued in the Great Lakes states focus on concentrations of PCBs and mercury in fish. The Great La...

In order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in Isfahan region. Protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and Pollen. Results showed that the longevi...

Two feeding trials were conducted to evaluate the influence of dietary curcumin level on fish meal replacement with poultry by-product (PBM) in a largemouth bass (Micropterus salmoides) diet. In trial I, reference diet (R) contained 400 g/kg meal, and PBM replaced 60 80% (P16 P8). II, containing 80 (P8) served as control (C), was added at 5000 10000 mg/kg (C5 C10), respectively. Replacement sig...

The chemical composition and protein quality of 11 alternative protein sources (chicken products, blood products, enzyme-hydrolyzed fish protein concentrate, soybean meal, and spray-dried pork liver) were determined, and an experiment was conducted to determine palatability and digestibility of processed red blood cell-containing diets. Chicken protein sources differed in concentrations of CP, ...

Ruminally undegraded protein (RUP) values of blood meal (n = 2), hydrolyzed feather meal (n = 2), fish meal (n = 2), meat and bone meal, and soybean meal were estimated using an in situ method, an inhibitor in vitro method, and an inhibitor in vitro technique applying Michaelis-Menten saturation kinetics. Degradation rates for in situ and inhibitor in vitro methods were calculated by regression...

A 10 week feeding trial was carried out to evaluate the replacement value of hatchery wastes for fish meal in the diet of laying Japanese quail (Coturnix coturnix japonica). 108 female Japanese quails (36 per treatment) were randomly allocated into 3 dietary treatments A, B and C which are fish meal (FM), whole hatchery waste meal (WHWM) and shelless hatchery waste meal (SHWM) based diets respe...

 The present study was carried out in order to establish an economical effective diet for the pacific white shrimp in the southern part conditions of Iran. Three dietary energy levels (E1=262, E2=312, E3=362 Kcal 100 g-1 diet) and 6 ratios of fish meal (FM): soybean meal (SBM) [(P1= 100% FM+ 0% SBM), (P2= 80% FM+ 20% SBM),(P3= 60% FM+ 40% SBM), (P4= 40% FM+ 60% SBM), (P5= 20% FM+ 80% SBM),(P6= ...

In recent years, interest has grown among poultry nutritionists in using alternative protein sources, such as insect meal, to meet the requirements of due sustainability concerns surrounding traditional sources soybean and fish meal. Insect meal can be produced from different insects, including black soldier fly, mealworms, house crickets, its nutrient composition varies depending on species, s...
