A study to assess acid values in soybean, cotton seed and sunflower oil commonly used in poultry ration was conducted. It was observed that mean acid value of oils kept in open were significantly high (7.67) than oil kept in sealed form (1.296). The mean acid value was higher in soybean oil (P less than 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 degree centigrade 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.
