Protein Nutrition in Fish-I

Trace minerals in fish nutrition

The role of trace elements in biological systems has been described in several animals. However, the knowledge in fish is mainly limited to iron, copper, manganese, zinc and selenium as components of body fluids, cofactors in enzymatic reactions, structural units of non-enzymatic macromolecules, etc. Investigations in fish are comparatively complicated as both dietary intake and waterborne mine...

Aquacultural production is a major industry in many countries, and it will continue to grow as the demand for "sheries products increases and the supply from natural sources decreases. As in more traditional forms of animal production, nutrition plays a critical role in intensive aquaculture because it in#uences not only production costs but also "sh growth, health and waste production (Gatlin,...

Metabolism and Nutrition: Nutrition I

The utilizable energy content of wheat distillers dried grains with solubles (wheat-DDGS) without or with supplementation of enzyme containing xylanase, amylase and protease (XAP) activities was deter­ mined for turkeys using linear regression method. A total of 126 BUT 10 male turkeys were fed a nutrient-adequate starter diet from d 1 to 14. On d 14, the birds were assigned to 6 dietary treatm...

Metabolism and Nutrition: Nutrition I

High levels of trypsin inhibitors (TI), one of the major anti-nutritional factors in SBM, can affect nutrient absorption and bird performance. Five soybean meals (SBM) ranging from 3,100 to 46,100 TIU/g were used in a performance trial to determine a threshold for trypsin inhibitors in the diet. The SBM products were grouped into 2 categories: cold pressed SBM and solvent extracted SBM. Of the ...
