THE EFFECTS OF DIFFERENT LEVELS OF OREGANO (Origanum vulgare) EXTRACT ON THE GROWTH PERFORMANCE OF NATIVE CHICKEN

The study was conducted to determine the effects of different levels of Oregano extract on feed consumption, water consumption, live weight gain, feed conversion efficiency, and economics of producing native chickens at Poultry Project of College of Agriculture, Mindanao State University, General Santos City in November 14,2018 to January 04,2019. The experiment was laid out in Completely Randomized Design (CRD) with four treatments the T1 - pure water, T2 - 10% oregano extract and T3 - 20 % oregano extract and T4-antibiotics (Ambroxitil®) added to water ration replicated three times. Birds without oregano extract consumed the lowest (3.89 kg/bird) feed consumption and the birds given antibiotics in water ration consumed 3.93 kg/bird while those given 100 ml and 200 ml oregano extract consumed the same and highest feed consumption (2.95 kg/bird). Birds given pure water consumed the highest water consumption (9.19 L/bird) while the birds given 200 ml (20%) oregano extract consumed the lowest water consumption (8.37 L/bird) and those birds given 100 ml (10%) oregano extract and antibiotics in water ration consumed 9.02 and 8.48 L/bird, respectively. Live weight gain ranged from 0.64 to 0.85 kg/bird. Income analysis show that the birds under T2 gave the highest Income Over Feed and Chick Cost with Php 7.64, followed by birds in T3, T4 and T1 with Php -5.85, Php -11.14 and Php-23.50,respectively.
