| Popis: | This study was conducted to investigate the effects of combination of linseed oil (rich in omega 3 polyunsaturated fatty acid, ω3 PUFA) and palm oil (rich in saturated fatty acid, SFAs) on the growth performance, meat quality, and fatty acid composition of birds under high environmental temperature. Experiment was conducted in summer (average high temperature 31°C). Birds in the positive temperature control group (PTC) and negative temperature control group (NTC) were fed with maize-soybean meal-maize gluten basal diet, the other 4 experimental groups were fed with basal diets containing linseed oil (LO), palm oil (PO), or their combination at the ratio of 3:2 (linseed oil/palm oil, w/w, group LPI) or 2:3 (group LPII), respectively. Results showed that the NTC deleteriously affect the growth performance, carcass quality and fatty acid composition of chickens than PTC group. The growth performance of birds under high environmental temperature was improved by oil supplementation. Furthermore, the combination of both oils achieved a better growth performance than the single oil during 22 to 42 d. Compared with NTC group, the yields of breast, leg and carcass were significantly improved in group LPI. Fatty acid composition of meat was significantly modified by dietary oil, and PUFA, especially ω3 PUFA in meat was increased by linseed oil (P |
