Effect on metabolism in salmonids


Despite the fact that the effects of feed ration and oil processing were minor, the combination of vegetable protein and oil sources had significant effects on growth, nutrient digestion and retention, intestinal enzymes and bile salt. A fatty acid tracer study revealed that the pyloric caeca was the most important site for absorption of both medium chain and long chain fatty acids in the gastrointestinal tract. Results A peruvian fish oil was refined, winterised (settling), randomised or added medium chain triglycerides or taurine. The processing of the oil had minor effects on growth, nutrient retention, blood glucose and insulin, intestinal proteolytic and lipolytic enzymes and bile salt concentration. The winterised oil lowered the blood cholesterol and had a positive effect on the digestibility of fat and energy.
