Effects of the Use of Ground Khaohom Mae Phaya Tongdam Paddy Rice in Diets on Productive Performance of Native Crossbred Chickens

Abstract

The objectives of this study were to determine the effects of the use of ground Khaohom Mae Phaya Tongdam paddy rice in diets on productive performance, survival rate, cost and profit of native crossbred chickens. Two hundred and forty 21-day-old native crossbred chickens of mixed sex were randomly allotted into a completely randomized design. All chickens were divided into 6 groups according to the level of ground Khaohom Mae Phaya Tongdam paddy rice in diets. Each group consisted of 4 replications with 10-chicken per replication. There were 6 formulated diets with containing 0, 5, 10, 15, 20, and 25 percent of ground Khaohom Mae Phaya Tongdam paddy rice. Feed and water were provided ad libitum. The experiment lasted for 16 weeks. The results showed that the native crossbred chickens with the use of ground Khaohom Mae Phaya Tongdam paddy rice in diets groups had no significant differences (P>0.05) in final body weight, weight gain, average daily gain, feed intake, and feed conversion ratio. The survival rate of all groups was 100 percent throughout the experimental period. The higher ground Khaohom Mae Phaya Tongdam paddy rice in diets was used, the cost of production increased. However, the use of 15 percent ground Khaohom Mae Phaya Tongdam paddy rice in diets gave the highest profit. Hence, it can be used 25 percent of ground Khaohom Mae Phaya Tongdam paddy rice in native crossbred chicken diet without any effects on productive performance of native crossbred chickens. But it will make the higher cost of production and the lower profit.
