USE OF FAT AS MAJOR ENERGY SOURCE IN BROILER PRODUCTION

Abstract

The terms "oil" refer to triglycerides of several profiles of fatty acids. Fatty acids that are not bound to other organic components as glycerol are the so-called free fatty acids. Lipids constitute the main energetic source for animals and they have the highest caloric value among all the nutrients. Supplying energy, the addition of fat to animal diets improves the absorption of fat-soluble vitamins, decreases pulverulence, increases diet palatability, and the efficiency of utilization of the consumed energy. Furthermore, it reduces the rate of food passage through the gastrointestinal tract, which allows a better absorption of all nutrients present in the diet. Considering diets with the same nutritive values, birds fed with rations containing oil present better performance than birds fed no oil. Moreover, the use of oil or fat in diets for broilers may change both the composition and the quality of the carcass. The study was conducted in Tangail district under the Dhanbari upazilla to observe the effect of oils in broiler ration as a energy source. The result reveals that the feeding of oil instead of maize has better performance.Three groups of birds were considered: 1) 61% oil group birds 2)46% oil group birds.3) Control group birds. The control group birds were fed with mixture of feed that are commonly used in broiler ration, in 61%& 46% oil diet contained palm oil as energy source. The performance of 61% oil group was better than 46% oil group & control group birds; on the other hand the 46% oil group birds were better in performance than control group birds. There was no mortality of birds during my experiment period. The total number birds were 100 in three study groups. Each group contained 33 birds and each of the groups were replicated thrice. There was no other abnormality observed in the birds.
