The aim of this paper is was to investigate the effects of soybean oil, flax and rapeseed oil on the body weight, fatty acid composition of lipids and sensory characteristics of chicken breast meat. At the beginning, six groups with 40 one day old chicks Cobb 500 hybrid line, with five replications was formed. Chickens were fed with three mixtures of 21, 20 and 18% protein, respectively. The experiment lasted 42 days. The use of different types of oils in the diet did not exhibited statistically significant (P>0.05) differences in body weight of chickens. The control group achieved final body weight of 2704g and 2695g, and the experimental groups in a row 2735, 2645, 2735 and 2670g. The use of flax oil and rapeseed oil changes the fatty acid composition of lipids. Replacing rapeseed with soybean oil reduces the percentage of palmitic, stearic and linoleic acids, and increases the share of oleic and linolenic acids in the abdominal fat pad. The inclusion of flax oil in the diet of chickens in an amounts of 4% and 8% increase the amount of linoleic acid to 63% and 203%, which was statistically highly significant (P<0.01) difference compare to the control groups I and II, whereas the amount of linoleic acid is reduced by 14% and 33%. Dietary addition of vegetable oils in this experiment did not show any improvement of chicken breast meat sensory quality, but lipids of meat was improved with the higher levels of PUFAs which contributes to a higher quality of gained chicken meat.

Dietary Conjugated Linoleic Acid

This study was conducted to investigate the effects of dietary conjugated linoleic acid (CLA) on fatty acid composition, lipoprotein content, lipid peroxidation, and meat colour of broiler chickens. A total of 180 broiler chickens were allocated to 3 dietary treatments (0, 2.5, and 5% Lutrell) and given a standard broiler starter diet and finisher diet. Body weight of chickens and feed intake were recorded weekly. After slaughter, the breast meat was aged at 4°C for 0, 3, and 6 days. The fatty acid composition was measured in the breast meat. Body weight (BW) and feed efficiency were decreased by dietary CLA level (P<0.05). Chicken fed with 2.5% Lutrell had the highest feed intake compared to the control (CON) group. The total CLA increased significantly (P<0.05) in breast meat from birds supplemented with CLA. Propensity for lipid peroxidation was significantly higher after 6 days of meat storage (P<0.05) and the redness in chicken breast meat was lower in CLA-fed birds (P<0.05). It is also notable that a 5% Lutrell supplementation decreased the plasma total cholesterol (TC), low density protein (LDL), and HDL (high-density lipoprotein)/LDL ratio in chickens (P<0.05).

Fatty acids of liver, carcass, and milk of rats fed corn oil, rapeseed oil, partially hydrogenated herring oil, or margarine were examined by gas–liquid chromatography. Appreciable quantities of linoleic acid were maintained in the tissues and milk, even when the hydrogenated herring oil with a low level of linoleic acid was fed. The proportion of C20and C22acids deposited or secreted was related to that of the diet, and was highest with rapeseed oil. In the livers of rats fed each diet, long-chain, polyunsaturated acids were observed. The fatty acids of milk more closely reflected the dietary pattern than did those of the tissues.

Lipid Fatty Acid Composition

This paper investigates the effect of soybean, flax and rapeseed oil on productive performance and lipid fatty acid composition of broiler chickens. Six groups of 40 one day-old chicks hybrid line Cobb 500, with five replications were formed. Three mixtures with 21, 20 and 18% protein were used. The first 14 days groups were fed with the starter mixture. The control group was based on the 4% and 8% soybean oil while in the experimental groups were included the same concentration of flax and rapeseed oil. The experiment lasted 42 days. At the end of the experiment 10 chickens from each group were sacrificed for examination of fatty acid composition of lipids. The control group achieved weight of 2704g and 2695g, and the experimental group in 2735, 2645, 2735 and 2670g, respectively. Feed conversion was improved with increasing the amount of oil in the diet. The usage of flax and rapeseed oil changed the fatty acid composition of lipids. Substituting soybean oil with rapeseed oil reduces the percentage of palmitic, stearic, and linoleic acids, and increases participation of oleic and linoleic acids in abdominal fat. The inclusion of flaxseed oil in the diet of chickens in the amount of 4% and 8%, increases the amount of linoleic acid by 63% and 203%, which is a statistically high and significant difference for the control group I and II, while the amount of linoleic acid is reduced by 14% and 33 %, which presents a statistically significant difference compared to group II.

The aim of this study was to investigate the effects of soybean, flax and rapeseed oil on productive performance and carcass quality of broilers chickens. At the beginning of the experiment six groups of 40 one day-old chicks, hybrid line Cobb 500 was formed, with five replications. For nutrition two feed mixtures were used. During the first two weeks, in preparation period, chickens were fed with starter mixture, and then with grower mixture until the end of the experiment. Control group was fed with mixture of standard composition and quality based on corn and soybean meal with the addition of 4% and 8% soybean oil, while the experimental group included 4% and 8% flaxseed oil and 4% and 8% rapeseed oil. The experiment lasted 35 days. During the experimental period, chickens were fed and watered ad libitum and microclimatic conditions were constantly monitored. Control of body weight and feed consumption was carried out every seven days. At the end of the experiment 10 chickens from each group were sacrificed for the purpose of testing the carcass quality. Upon completion of the experiment, control group achieved weight of 2122g and 2053g, and the experimental group with flax oil 2164g and 2094g, and the group with rapeseed oil weighs of 2121g and 2081g. Chickens on treatment with 4% flax oil in the diet achieved significantly higher body mass (P<0.05) at the end of the experiment compared with the groups who were on treatment with 8% rapeseed and soybean oil. Soybean oil at a rate of 4% showed significantly (P<0.05) increased final body weight compared to body mass of chicks in a group with the addition of 8% soybean oil. Feed conversion ratio was lowest in the group with the addition of 4% flax oil and rapeseed oil, and the highest in the group with the addition of 8% flax oil. The differences found in the carcass quality between the control and experimental groups were not statistically significant (P>0.05). The largest amount of abdominal fat (18.9 g) was in the group with the addition of 4% rapeseed oil and lowest in the group with the addition of 8% soybean oil (12.6 g). Based on these results it can be concluded that the addition of 4% oil showed better productive results, but had no effect on carcass quality of chickens.
