The mechanisms of the effects of different oils with different fatty acid profiles on poultry performance remain poorly understood. Therefore, the aim of this study was to investigate the duodenal activity of digestive enzymes and the digestibility of nutrients in the diets of laying hens fed different oils in the same diet (sunflower, soybean, rapeseed and linseed oils, 2.6% of the total diet). The test was conducted on 10 laying hens of the Hysex white cross with chronic duodenal (7 birds) or ileal (3 birds) fistulas. Different oils influenced lipase and alkaline phosphatase activity in duodenal chyme. The highest lipase and alkaline phosphatase activity was found when soybean oil was administered. At the same time, there was a significant (P |
