“…This result is consistent with other reports for broiler chicks (Phetteplace & Watkins, 1989;Olomu & Baracos, 1991a). Studies using whole flaxseed for poultry diets have shown that whole eggs and various tissues are enriched with n-3 PUFAs derived from dietary α-linolenic acid (C18:3n-3) (Caston & Leeson, 1990;Cherian & Sim, 1991;Jiang et al, 1991).…”

Different combinations of saturated and unsaturated fatty acids were fed to broilers to establish their effect on the fatty acid composition of the broiler carcass and the abdominal fat pad. Six combinations of Canola acid oil (CAO, high levels of C18:3n-3 and monounsaturated fatty acids) and Famarol acid oil (FAO, high levels of C18:2n-6 and saturated fatty acids) were included in the broiler diets from one day of age to six weeks of age, viz. 100% FAO, 80% FAO-20% CAO, 60% FAO-40% CAO, 40% FAO-60% CAO, 20% FAO-80% CAO, 100% CAO. There were no statistically significant differences between dietary groups in weight gain (1.71 ± 0.059 kg) or feed conversion ratios (1.97 ± 0.051 g feed/g gain). No significant differences between treatments were found in the moisture (66.20 ± 0.112%), protein (17.63 ± 0.484%), lipid (15.92 ± 1.507%) and ash (0.95 ± 0.115%) concentration of the carcasses, nor in the moisture (28.77 ± 0.112%), protein (3.03 ± 0.484%), lipid (63.32 ± 9.789%) and ash (0.45 ± 0.135%) concentrations of the abdominal fat pads. With the increase in dietary CAO levels, the mean percentages of C18:2n-6 and C20:4n-6 in the carcasses decreased respectively with 1.78% units from 20.88% and 0.35% units from 1.05%, whilst C18:3n-3 and longer chain n-3 fatty acids such as C20:5n-3 and C22:6n-3 increased respectively with 2.25% units from 1%, 0.1% units from 0.1% and 0.67% units from 0.2%. The same tendency was seen in the abdominal fat pads where C18:2n-6 and C20:4n-6 decreased respectively with 1.55% units from 20.75% and 0.98% units from 1.2% with an increase in dietary CAO, whilst C18:3n-3, C20:5n-3 and C22:6n-3 increased respectively with 2.13% units from 1.15%, 0.45% units from 0.03% and 0.95% units from 0.05%. The n-3/n-6 ratio in the carcasses and abdominal fat pads increased respectively with 0.16% units from 0.06% and 0.19% units from 0.06% with an increase in dietary CAO. These results clearly indicate that dietary CAO enriched with α-linolenic acid lowered the saturated fatty acid concentrations in broiler carcasses and abdominal fat pads with 4.88% units and 10.63% units respectively, and increased the monounsaturated fatty acid concentrations with 3.87% units and 7.25% units, respectively and polyunsaturated fatty acid concentrations with 1.02% units and 2.38% units, respectively. The results of this experiment showed that substitution of Famarol oil with Canola oil in broiler diets can increase the ratio of n-6 to n-3 fatty acids in broiler carcasses and abdominal fat pads to 5:1, a ratio more suitable for human health. Increasing the level of n-3 fatty acids in the diets was also effective in reducing the level of saturated fatty acids in the carcasses and abdominal fat pads of broiler chickens resulting in "healthier" chickens.

“…In the current study, growth performance of broiler chickens in days 21-42 and 1-42 of treatment was in line with previous reports that the substitution of some (Olomu and Baracos 1991) or all (Benatmane et al 2011) dietary oil with FO did not significantly affect weight gain, feed consumption, and feed efficiency. The study of Rahimi et al (2011) showed that BW gain during days 1-21 did not differ by feeding 7.5% FO, but it decreased with adding the amount of 10%, which is completely opposite to our result of the elevated BW gain at 21 days by FO1 treatment (replacing 1.25% CO by FO).…”

ABSTRACT:The effect of different levels of corn oil (CO) and flaxseed oil (FO) on growth performance, blood characteristics, fatty acid composition, and expression of lipogenic genes in the liver of broiler chickens was studied. Two hundred forty female Cobb-500 broiler chickens at the age of one day (body weight (BW) = 46 ± 4 g) were fed a corn soybean meal based diet containing 5% CO (LC), 3.75% CO + 1.25% FO (FO1), 2.5% CO + 2.5% FO (FO2) or 5% FO (FC). Chickens fed FO1 diet had better BW gain (P = 0.049) and gain/feed ratio (P = 0.006) than those fed LC and FC diets during days 1-21 of age. However, for the whole experimental period (1-42 days of age), the dietary lipid source had no effect on the growth performance. On day 42 of age, the hepatic percentages of 18:3n-3 (P = 0.001) and 20:5n-3 (P < 0.001) were higher in FC than in LC group, which led to a higher content of total n-3 PUFA and lower n-6/n-3 PUFA ratio. The contents of 18:2n-6 (P < 0.05) and Σ n-6 PUFA (P = 0.009) were lower in FC than in LC group. Chickens fed FO1 and FO2 diets had higher Ca 2+ -ATPase activity and lower lipoprotein lipase activity than those fed LC and FC diets, whereas activities of lactate dehydrogenase and Na + ,K + -ATPase were increased by FO2 than by LC diet (P < 0.05). The relative mRNA expression level of lipin 1 in chickens fed FO2 and FC was higher (P < 0.01) than in those fed LC and FO1 diets. Our results demonstrated that higher levels of FO led to hepatic enrichment of n-3 PUFA content and lower n-6/n-3 PUFA ratios in liver and increased the expression of lipin 1 whereas the expression of lipin 2, NADH dehydrogenase subunit 2, Δ-6 fatty acid desaturase, WD and tetratricopeptide repeats 1, and glyceraldehyde-3-phosphate dehydrogenase was not affected.

“…This fact corroborated the observation of Crespo and Esteve-Garcia (2001), who concluded that the supply of flax oil containing a high level of LNA did not influence the content of SFA in meat. Olomu and Baracos (1991) performed an experiment with feeding linseed oil with a high content of LNA. Their observation that the amounts of MUFA, especially oleic acid, were depressed, was not proved.…”

Effects of 1, 3, 5 or 7% of linseed oil in the diet on the content of fatty acids in breast and thigh meat were studied in broiler chickens. Oils made either of seeds of the linseed cultivar Atalante (A) with a high content of α-linolenic acid or of the cultivar Lola (L) with a predominating content of linoleic acid were fed from 25 to 40 days of age. When feeding A, the contents of all n-3 polyunsaturated fatty acids (PUFA), including eicosatrienoic acid, were significantly higher, those of n-6 PUFA were lower, and the ratio of n-6/n-3 PUFA was narrower (P < 0.001) than when L was fed. The narrowest n-6 to n-3 PUFA ratio was observed at the content 36 g of α-linolenic acid (58 g A) per kg of the diet while the widest one at 2 g of α-linolenic acid (70 g L) per kg of the diet. When using L, the increasing level of linoleic acid in feed was associated with significantly increasing levels of all n-6 PUFA in meat. The content of all n-3 PUFA increased after the application of oil A, but the dependence for eicosapentaenoic acid in thigh meat was expressed significantly more precisely by the second degree parabola with the maximum at the level of 37 mg of α-linolenic acid and for clupanodonic and docosahexaenoic acids by parabolas with maxima at the level of α-linolenic acid in the diet 41 g and 30 g for breast meat and 35 g and 27 g for thigh meat, respectively. By means of the inclusion of linseed oil with a high content of α-linolenic acid in the feed mixture it would be possible to produce poultry meat with a high content of n-3 PUFA as a functional food.
