Partial Replacement of Fish Oil with Vegetable Oils in Diets for EuropeanSeabass (Dicentrarchus labrax): Effects On Growth Performance and FattyAcids Profile

KENAN ENGİN

The study was conducted to determine the effects of alternative oil sources on growth, body composition and feed conversion of sea bass individuals. The tested oils used in the study were as follows: sesame oil (SO), canola oil (CO) and soybean oil (SBO). All tested oils were included at a 50% substitution level of fish oil and were compared with a control diet containing 100% fish oil (FO). There was no effect of diet on specific growth rate. The highest final weight was seen in fish fed SO and FO diets compared to that of fish fed CO diet and SBO diets (P0.05). In the n-6 fatty acids, fish f ...Daha fazlası

Potential of Cottonseed Oil as Fish Oil Replacer in European Sea Bass Feed Formulation

KENAN ENGİN

Triplicate groups of 20 European sea bass (35 g) were fed five diets in which the added lipid was 100% fish oil (FO), 40% (CSO40), 60% (CSO60), 80% (CSO80) and 100% (CSO100) refined cottonseed oil (CSO), for a period of 120 days. Overall fish growth, feed conversion ratio and protein utilization were unaffected by dietary treatment, but hepatosomatic and visceral fat indexes increased with increasing dietary CSO. Fillet fatty acid composition of total lipids reflected the fatty acids in the test diets. The monounsaturated fatty acids were significantly higher in fillet of fish fed diet FO, CSO ...Daha fazlası

Effects of Dietary Cottonseed and/or Canola Oil Inclusion on the Growth Performance, FA Composition and Organ Histology of the Juvenile Rainbow Trout, Oncorhynchus mykiss

KENAN ENGİN

This study aimed at demonstrating the effects of total and 50% dietary fish oil replacement by cotton seed and canola oils and a mixture of these vegetable oils (VOs) on growth, tissue fatty acid composition and histology of digestive organs in the juvenile rainbow trout for 84 days. Five iso-nitrogenous and lipidic diets were formulated to replace dietary fish oil (FO) totally by cotton seed oil (CSO), canola oil (CO) and an equal or 50% FO/ 50% VO mixture. Duplicate groups of 50 fish (~15 g) were fed two times daily to apparent satiation. Growth performance, feed efficiency and viscerosomati ...Daha fazlası

Effects Of The Feeds Containing Different Plant Protein Sources On Growth Performance And Body Composition Of Rainbow Trout (Oncorhynchus mykiss W )

MURAT BİLGÜVEN | MUSTAFA BARIŞ

In this study, a total of 720 rainbow trout (Oncorhyncus mykiss) having 50.08±0.19 g of average initial weight were used to compare of usage of the soybean meal, sunflower meal, canola meal and cottonseed meal as the best plant protein source. Four different feeds which contain soybean meal (SBM), canola meal (CM), sunflower meal (SFM) and cotton seed meal were used, respectively. Four trial groups were tested in triplicate during 12 weeks. Experimental diets were prepared as isonitrogenous significantly difference among the groups for average feed consumption, condition factor and survival ra ...Daha fazlası
