“…Present finding is consistent with earlier reports that high dietary linseed oil lowered the growth performance of tilapia (Li et al, 2016;Francis et al, 2006). Moreover, earlier reports indicate that high dietary n-3 polyunsaturated fatty acids (PUFAs) depressed growth in hybrid tilapia and tilapia zillii (Huang et al, 1998;Kanazwa et al, 1980). In contrast, replacing FO with linseed oil at higher levels had no effect in the growth of Atlantic salmon and Murray cod (Menoyo et al, 2005;Turchini et al, 2011).…”

The present study evaluated the impact of varying dietary linseed oil composition on growth, survival and tissue polyunsaturated fatty acids (PUFA) profiles in Nile tilapia (Oreochromis niloticus). Five isonitrogenious diets with varying linseed and sunflower oil concentrations were formulated and fish fed twice daily to for 3 months. Commercial diet was used as a control in triplicate tanks set for each diet treatment. Growth parameters were measured from changes in body weight and length. A 75:25 ratio of sunflower oil to linseed oil gave a better survival and specific growth rate than 100% linseed oil or 100% sunflower oil. Tissue PUFA composition were determined using gas chromatography. High dietary linseed oil composition (100%) resulted into significantly high (P<0.05) total n3 fatty acids (9.9-25%) and DHA (1.8-7.9%) in muscles whereas liver n3 fatty acids and DHA composition ranged between 9.3-25.5 and 0.7-2.6%, respectively. Muscle and liver n3/n6 ratio ranged between 0.7-2.2 and 0.7-2.6 while tissue arachidonic acid (ARA 20.4 n6) content ranged between 2.6-3.5% in muscles and 3.4-4.5% in the liver. ARA 20.4 n6 values were low relative to the dietary precursor, linoleic acid, LA, 18.2 n6. Fatty acid deposition in the tissues increased with the feeding period with the third feeding month recording significantly higher DHA, total n3 and n3/n6 ratio. Based on the result, dietary linseed oil > 50% reduced growth and survival rate in tilapia, however, it increased tissue accumulation of essential fatty acids which also increased with the length of feeding period.

“…This research supports the results achieved in this study. Additional previous studies have also reported greater growth in the cases where dietary vegetable oils were used in place of fish oil in some fish species such as South American catfish (Arslan et al 2008), rainbow trout Oncorhynchus mykiss (Rinchard et al 2007), African catfish (Hoffman and Prinsloo, 1995;Ng et al 2003), and hybrid tilapia (Huang et al, 1998;Ng et al, 2001). In freshwater fish species, LA and LNA will fulfill the essential fatty acid requirements because freshwater fish have the ability to convert these fatty acids to longer chain n-3 and n-6 PUFA (Sargent et al, 1995).…”

“…However, in some freshwater fish such as African catfish Clarias gariepinus (Hoffman and Prinsloo, 1995;Ng et al, 2003), hybrid tilapia Oreochromis niloticus × O. aureus (Huang et al, 1998;Ng et al, 2001) and South American catfish Pseudoplatystoma fasciatum (Arslan et al, 2008), growth depletion was observed when they were fed diets based on fish oil. Nevertheless, important changes in fatty acid composition in favor of n-6 fatty acids (Ng et al, 2003;Arslan et al, 2008) and lipid accumulation (Caballero et al, 2003) were evident when vegetable oil was substituted in place of fish oil.…”

Brown trout Salmo trutta (~1 g) were fed four casein-gelatin based diets with different lipid resources for 6 weeks. The sources of dietary lipid were menhaden oil (MO diet), hazelnut oil (HO diet,), a blend of linseed oil and soybean oil (1:1) (LO+SO diet), and soybean lecithin (LE diet). Feeding trial was conducted in a recirculating water system at 13±0.2°C. Fish fed LO+SO diet demonstrated the highest growth performance while those fed HO diet had the lowest growth rate (P<0.05). The fatty acid profiles of fish reflected the fatty acid composition of the diets. High level of docosahexaenoic acid (22:6n-3, DHA) in whole body lipids of fish fed LO+SO diet corresponded with the high level of linolenic acid (18:3n-3, LNA) in the lipids of this diet. Fish fed LE diet which was rich in linoleic acid (18:2n-6, LA) had the highest level of arachidonic acid (20:4n-6 , ARA) in their body. The results suggest that the efficiency of elongation and desaturation of C18 fatty acids depends on the dietary lipid source and brown trout has capacity to transform LA and LNA to ARA and DHA, respectively. Growth depletion in fish fed HO diet might be caused by essential fatty acid deficiency.Keywords: Brown trout, Salmo trutta, lipids, fatty acids, growth. Balık Yağı Yerine Kullanılan Farklı Diyetsel Bitkisel Yağların Kahverengi Alabalık (Salmo trutta) Yavrularında Büyüme ve Yağ Asidi Kompozisyonuna Etkisi ÖzetMevcut çalışmada yaklaşık 1 g ağırlığındaki kahverengi alabalık yavruları 6 hafta süre ile kazein-jelâtin tabanlı yemlerle beslenmiştir. Yemlerde yağ kaynağı olarak balık (ringa) yağı (MO diyeti), fındık yağı (HO diyeti), soya yağı-keten tohumu yağı karışımı (1:1) (LO+SO diyeti) ve soya lesitini (LE diyeti) kullanılmıştır. Kapalı devre su sisteminde yürütülen çalışma boyunca sıcaklık 13±0,2°C olarak gerçekleşmiştir. Çalışma sonunda LO+SO yemi ile beslenen balıklar diğer yemlerle beslenen balıklara göre önemli derecede yüksek büyüme performansı göstermiştir (P<0,05). En düşük büyüme HO yemi ile beslenen balıklarda görülmüştür. Tüm vücuda ait toplam yağların nötral ve polar lipit fraksiyonlarının yağ asidi içerikleri yemlerin yağ asidi içeriklerini yansıtmıştır. Yüksek düzeyde linolenik asit (18:3n-3, LNA) içeriğine sahip LO+SO diyeti ile beslenen balıkların vücudunda, dokozahekzaenoik asit (22:6n-3, DHA) miktarında artış görülmüştür. Benzer şekilde en yüksek araşidonik asit (20:4n-6, ARA) içeriği, 18:2n-6 (linolenik asit, LA) bakımından zengin olan LE diyeti ile beslenen balıklarda görülmüştür. Mevcut çalışmanın sonuçları, kahverengi alabalıkta yemlerdeki yağ kaynağına bağlı olarak LA ve LNA in sırasıyla ARA ve DHA e dönüştürebildiğini göstermektedir. Fındık yağı ile beslenen balıklardaki düşük büyümenin esansiyel yağ asidi eksikliğinden kaynaklandığı düşünülmektedir.Anahtar Kelimeler: Kahverengi alabalık, Salmo trutta, yağlar, yağ asitleri, büyüme.

“…Deaver et al (1986), Brasitus et al (1985) and Thi-Dinh et al (1990) found that feeding rats a high unsaturated fat diet decreased the phospholipid concentration in liver, enterocytes and the plasma membrane of adipocytes, respectively. Feed stuffs rich in PUFA, like pasture and WDGS, are known to increase the proportion of PUFA in muscle tissue phospholipids of beef (Dannenberger et al 2007), fish (Huang et al 1998) and pork (Nurnberg et al 1998). Mead et al (1980) further suggested lipid oxidation can increase the activity of phospholipases to remove esterified fatty acids.…”

Abstract. Feeding wet distillers grains plus solubles (WDGS) increases polyunsaturated fatty acid (PUFA) levels in beef. It was hypothesised that WDGS in feedlot diets increases PUFA concentration in the sarcoplasmic reticulum (SR) membrane, thereby altering membrane integrity, resulting in more rapid intracellular calcium leakage and improved tenderness. The objective of this study was to evaluate this hypothesis. Ninety-six crossbred steers were fed either a corn-based diet with 0% WDGS or 50% WDGS. Fifteen strip loins per treatment were collected, fabricated into steaks, aged and placed under retail display conditions. Steaks were used to measure tenderness, proteolysis, free calcium concentrations, lipid oxidation, sarcomere length and SR membrane fatty acid, phospholipid lipid, neutral lipid and total lipid profiles. Compared with steaks from steers fed 0% WDGS, steaks from steers fed 50% WDGS were more tender (P < 0.05) and had greater (P < 0.05) free calcium concentrations early post-mortem. Feeding 50% WDGS also tended to increase (P < 0.10) total PUFA concentrations, decrease (P < 0.10) total phospholipid concentration and increase (P < 0.10) total neutral lipid concentration for SR membrane. Steaks from steers fed 0% WDGS had greater (P < 0.05) lipid oxidation (TBARS values) than steaks from steers fed 50% WDGS after extended aging. Although differences in tenderness between the two treatments were detected, there were no corresponding differences (P > 0.10) in sarcomere length or proteolysis. This study showed that feeding WDGS may increase tenderness, possibly by increasing free calcium in muscle early post-mortem. However, the true mechanism that contributes to these differences is still unclear.
