Effects of some oils used in broiler rations on performance and fatty acidcompositions in abdominal fat

This study was carried out to examine how the fatty acid compositions of oi ls (sunflower, cotton, corn, flaxseed, soybean, olive, fish, tallow and ren dering oils) were reflected in the products and their effects on the growin g performance of broilers. Trial was carried out to determine the effects of the same fat sources on t he performance of the broilers and fatty acid compositions of abdominal fat with totally 414 broiler chicks. Feed consumption, body weight, feed conve rsion, abdominal fat/carcass yield and fatty acid levels of abdominal fat w ere determined. At the end of trial, the lowest moderate body weight were found to be 1957. 10; 1901.20; 2197.20; 2072.76; 2080.30; 1943.20; 1887.30; 2074.00; 2099.20 g, respectively. The lowest daily body weight increase was also observed at the group fed the fish oil (37.53 g) and the greatest daily body weight in creased at the group fed the corn oil (43.85 g). The lowest feed conversion ratio 1.95 kg was observed at the group which consumed the ration containi ng corn oil. In samples of abdominal fats taken from broilers which consume d omega-3-rich fats, omega-3 fatty acids, showing omega-3/omage-6 fatty aci ds ratio significantly increased. The fat content and fatty acid compositio n of abdominal fat were determined. The level of fatty acid from the group consumed flax oil that was rich in omega-3 was observed the highest (15.62 %), while the lowest level (2.02 %) was found in the group administered wit h rendering oil. Of all groups, the highest level (52.33 %) of saturated fa tty acid was obtained from the group Fed ration contained tallow Consequently, the compositions of fatty acids from these sort of animal pro ducts presented for human consumption was seen to highly alter depending on nutrition. Especially, following consumption flax and oil, the ratio I, om ega-3 appeared to increase. The person who consume those might be peculated to be in low risk of being disordered by heart-vessel diseases.
