Abstract   

    A study to assess acid values in soyabean, cotton seed and sunflower oil commonly used in poultry ration was conducted. It was observed that mean acid value of oils ~ept in open were significantly high (7.67) than oil kept in sealed form (1.296). The mean acid value was higher in soyabean oil (P<0.01) than the values in cotton seed oil and sunflower oil. While determining the effect of Santaquin, BHT and Oxistat as antioxidant, in the ration stored at 40 °C for 2 months, it was observed that the acid values in untreated control ration was 18.20 while with the added antioxidants were 4.88, 4.85 and 4.83, respectively showing a significant increase with each week of the storage.

Key words: Soyabean oil, Cotton seed oil, sunflower oil, Acid value, Antioxidant.
