| Summary: | This study was conducted to evaluate the effect of different levesl of dietary soybean oil and acidulated sunflower oil soapstock on performance, egg quality and fatty acid profile of egg yolk in laying hens, . A total of 75, 44-week-old Hy-Line W36 laying hens were distributed into five treatments according to a completely randomized experimental design, consisting of soybean oil, acidulated sunflower oil soapstock (ASS) dietary inclusion levels (25, 50, 75 and 100 %), with five replicates of three birds each. The experiment was lasted in 84 days. Dietary treatments had no significant effect on body weight change, egg production, feed intake, feed conversion ratio, egg weight and egg mass. The dietary inclusion of ASS i had no significant effect on egg specific gravity, egg shell breaking strength, egg shell weight and egg shell thickness, egg shape index, albumen index, yolk index, albumen pH, yolk pH but haugh unit L, a, b color value. . The inclusion of different levels of soybean oil and ASS in the diet of laying hens had no significant effect on palmitic, palmitoleic, stearic, oleic, linoleic and linolenic acid contents of egg yolk. It is concluded that the soybean oil can be replaced by ASS without any adverse effect on performance and egg quality in laying hen diets. |
