This book was released on 1987 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of different dietary lipids on the growth, nutrition and tissue lipid profiles of rainbow trout raised to market size on a commercially available ration were examined. Rainbow trout of 80 g mean initial weight were fed pellets prepared according to Oregon Moist Pellet specifications for 20 weeks. Salmon oil (0MP-1), soybean oil (OMP-2), linseed oil (OMP-3), chicken fat (OMP-4), pork lard (OMP-5) and beef tallow (OMP-6) were used for the 6% lipid component of the diets. No differences in feed conversion or growth rate were observed across diet groups. Trout nutrition was monitored by three blood parameters -- red blood cell (RBC) fragility (hemolysis), packed cell volume (PCV) (hematocrit), and percent hemoglobin. The OMP-1 diet appeared to have caused oxidative stress in trout as measured by hemolysis, while hematocrit and percent hemoglobin values were uniform across diet groups. Tissue levels of total n-3 fatty acids were highest in the OMP-3 group and decreased in the order OMP-1> OMP-2 = OMP-4 = OMP-5 = OMP-6. However, unaltered linolenic acid (18:3 n-3) comprised almost 50% of the n-3 fatty acid content of OMP-3 trout tissue lipid. The level of total 20:5 n-3 plus 22:6 n-3 (18%), was 33% higher in tissue from OMP-1 trout than tissue from all other diet groups which held fairly constant at 12% across OMP groups 3-6. The lowest tissue level of total 20:5 n-3 plus 22:6 n-3 was found in the OMP-2 trout, 10%. Trout raised on the OMP-1 diet also retained higher tissue stores of 20 and 22 carbon monoenes than trout fed OMP diets 2-6, but less than dietary levels. In contrast, trout fed OMP diets 2-6 retained higher tissue levels of these same fatty acids than dietary levels. The diet ratio of polyunsaturated fatty acids (PUFA)/22:1 appeared to influence whether 22:1 was conserved or oxidized. The most favorable balance of trout tissue monoenes, n-6 fatty acids and total 20:5 n-3 plus 22:6 n-6 for human health was found in trout fed the OMP-6 diet.

This book was released on 1986 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two rainbow trout (Salmo gairdneri) reference diets (a practical reference (control) diet (C201) formulated for feed development studies and semipurified reference (basal) diet (C101) for nutrient requirement studies) were used in a 16-wk feeding trial to investigate their suitability for Arctic charr (Salvelinus alpinus). Biochemical and performance parameters together with gross morphological and histological evidence showed that diet C201 was a suitable reference diet for feed development studies in Arctic charr. It produced no pathological conditions. However diet C101 was not suitable for nutrient requirement studies in Arctic charr; compared to diet C201 it produced high mortalities, lower weight gains (growth) and low hematocrit values. It resulted in liver which was beige-gray in color, had an abnormal glycogen distribution and accumulation and had a higher weight to body weight ratio. This abnormal liver had a higher content of lipid (dry weight), moisture, calcium, iron and cobalt and a lower content of fat-free solids, copper, magnesium, and zinc. Diet C101 also produced higher whole body contents of manganese, and cobalt and lower content of selenium.

Pustowka and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One hundred two-year-old rainbow trout (Oncorhynchus mykiss) were fed one of the four treatment diets for 16 months. The diets differed only in the additional source of lipid which comprised 12% of the total diet. Herring oil (adequate n-3 fatty acids), menhaden oil (high in n-3 fatty acids), safflower oil (high in n-6 fatty acids) or tallow (high in saturated fatty acids) were the sources of dietary lipid.

Download or read book Some Effects of Cyclopropenoid Fatty Acids on Lipid Metabolism in Rainbow Trout Salmo Gairdnerii written by Caroll Marie Combs and published by . This book was released on 1967 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diets containing cyclopropenoid fatty acids (CPFA) were fed to rainbow trout. At a level of 223 ppm (from Sterculia foetida oil), these CPFA in six weeks reduced weight gain by as much as 50 percent over the control fish on the same diet without CPFA. Compounds containing the intact cyclopropene ring were recovered from the tissue lipids of the trout at approximately two-thirds of the level fed. These acids seemed to concentrate in the egg lipids of the adult female fish. At 223 and 2233 ppm (from S. foetida oil) and 50 ppm (from food grade cottonseed flour) the CPFA were demonstrated to alter lipid metabolism. In general, the CPFA fed fish had higher stearic and palmitic acid levels and lower oleic and palmitoleic acid levels in their tissue lipids than did the controls. On diets containing corn oil or corn oil plus salmon oil, fish fed CPFA tended to deposit more long chain unsaturated fatty acids than did their controls. When provided with tristearin as the sole dietary lipid, the CPFA fed fish reduced the level of unsaturation of their tissue lipids.
