Exposure to Bacillus thuringiensis (Bt) toxins in low- and moderate-dose transgenic crops may induce sublethal effects and increase the rate of Bt resistance evolution, potentially compromising control efficacy against target pests. We tested this hypothesis using the fall armyworm Spodoptera frugiperda, a major polyphagous lepidopteran pest relatively tolerant to Bt notorious for evolving fiel...

 This study was carried out to investigate the apparent digestibility coefficients (ADCs) value of protein, amino acid and energy and body amino acid composition of rainbow trout fed solvent extracted soybean meal (SBM) and full-fat soybean meal (FFS) partly replacing fish meal (FM) in diets. Five iso nitrogenous (average 50.36% crude protein) and energetic (4294 kcal/kg total energy) diets wer...

One-day-old broiler chickens were fed on a control diet based on maize and maize starch or diets containing 30 g/kg of 89% deacetylated chitin (chitosan) or low-methoxyl (34% degree of esterification) pectin. Feeding of the chitosan diet to chickens significantly reduced body weights and feed intakes compared with animals fed on control or pectin diets on days 5 and 11 of the experiment. On day...

The kinetics of urea metabolism were measured in children recovering from severe malnutrition. For a period of up to 10 d they received one of four diets which provided 711 kJ (170 kcal)/kg per d. Two groups received a diet with a high protein:energy (P:E) ratio of 10-6% (HP), enriched with either fat (HP/F) or maize starch and sucrose (HP/C). Two groups received a diet with a low P:E ratio of ...

this study was designed to determine the effects of dietary replacement of fish oil with canola oil ongrowth performance, feed efficiency of body and economic indices of experimental diets of juvenilecommon carp (cyprinus carpio). during the experiment 270 juvenile fish with an average initialweight of 16.24 ± 0.10g were randomly distributed in 18 well aerated cylindrical polyethylene tanks(15 ...

Ruminant husbandry constitutes the most important source of anthropogenic methane (CH4). In addition to enteric (animal-derived) CH4, excreta are another source of CH4, especially when stored anaerobically. Increasing the proportion of dietary concentrate is often considered as the primary CH4 mitigation option. However, it is unclear whether this is still valid when diets to be compared are en...

The rural population in many parts of India consumes sorghum (Jowar) and maize as staple food. The flour made out of these cereals is consumed after cooking or baking on a pan with or without oil. The present study was undertaken in two groups of healthy human volunteers. Each subject of first group consumed ground unrefined sorghum (100g) daily as supper for three weeks in the form of pancake....

This study was designed to compare the effect of kola testa, which is rich in fibre with maize conventional energy source and other sources such as corn bran rice bran. A total two hundred forty African giant land snails (Archachatina marginata) an average live weight 177.69 ± 10.87g were assigned four dietary treatments: a maize-based diet (Diet 1) served control, completely randomized design....
