Nutrient composition of the grasshoppers Oxya hyla hyla showed that they are a rich nutrient source containing 687.7 g protein/kg of dry body weight. Their antinutrient values fell within nutritionally acceptable values of the poultry bird Coturnix japonica japonica (Japanese quail). The most required essential amino acids and fatty acids were also present in sufficient amount. For feeding tria...

Production of crystalline l-Thr results in the generation of a Thr biomass that contains more than 80% CP, 5.20% Lys, 5.10% Val, 4.52% Thr, 4.15% Ile, and 1.06% Trp. This Thr biomass product can possibly be used as a feed ingredient in diets fed to weanling pigs, but there is little information about the nutritional value of this product. The objective of this work was to determine the AA diges...

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...

 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= ...

  Apparent digestibility coefficients (ADC) were calculated by using chromic oxide in the diet as an indigestible marker to evaluate the Iranian Cottonseed meal (CSMP) . Then, the nutritional value of cottonseed meal ( ‍ CSM) as soybean meal (SBM) substitute in quality low cost rainbow trout (Oncorhynchus mykiss) ration was investigated. In this study, six formulated feeds consisting different ...

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...

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...
