Two rapeseed (Brassica napus) meals, RM1 and RM2, with two levels of glucosinolates (GLS; 5 and 41 mumol/g DM respectively) were incorporated at the levels of 300 and 500 g/kg of the diets of juvenile rainbow trout (Oncorhynchus mykiss) in replacement of fish meal, and compared with a fish-meal-based diet. A decrease in the digestibility of the DM, protein, gross energy and P was observed with ...

This study examined the effects of substituting fish oil and fish meal with a blend of alpha-linolenic acid (ALA, 18:3 n-3) rich vegetable oils (14%, w/w) and defatted poultry meal (34%, w/w) in a formulated diet, on growth and tissue fatty acid profiles in barramundi fingerlings. Results indicated that on average, while the ALA levels of the barramundi liver and fillet increased with increasin...

The study was designed to test the effects of dietary supplementation with fish meal or specific n-3 fatty acids on ovarian activity and uterine responses in early lactating cows. From 5 to 50 d in milk (DIM), cows were fed diets that were isonitrogenous, isoenergetic, and isolipidic containing none (control), 1.25, 2.5, or 5% menhaden fish meal (FM) or 2.3% Ca salts of fish oil fatty acids (Ca...

Although chronic fish oil intervention had been shown to have a positive impact on vascular reactivity, very little is known about their acute effects during the postprandial phase. Our aim was to examine the impact of a fish oil-enriched test meal on postprandial vascular reactivity in healthy younger ( < 50 years) v. older ( > or = 50 years) men. Vascular reactivity was measured at baseline (...

The main objective of this study was to evaluate alternate vegetable proteins as a replacement for fish meal in diets of Labeo rohita and Ctenopharyngodon idella and use the findings to formulate a cost effective diet for freshwater fish species. Fish of an average weight of (L. rohita 1.91±0.05; C. idella 19.57±0.09 g) was stocked in four earthen fish ponds. The feed was prepared from five dif...

Experiments were conducted to compare endogenous amino acid losses and the true amino acid availability (TAAA) of 3 feedstuffs by using methods involving a short-term fasting and an N-free diet with cecectomized ganders. Diets were formulated to contain soybean meal, fish meal, and cottonseed meal as the sole source of protein. A precision-fed assay was used in which each feed sample was precis...

Two pond experiments were conducted to evaluate cottonseed meal (CSM), distiller’s dried grains with solubles (DDGS), and supplemental lysine as replacements for soybean meal (SBM) in channel catfish diets. In Experiment 1, fish fed diets in which SBM was totally replaced with CSM gained similar weight as fish fed control diet, but fish fed CSM diet in Experiment 2 had 9.5% lower weight gain th...
