Abstract: VILLA, RONALYN N. Supplementation of Fresh Oregano (Coleus aromaticus Benth.) Leaf Extract in the Drinking Water of Male Broilers. Undergraduate Thesis. Bachelor of Science in Agriculture major in Animal Science. Cavite State University, lndang, Cavite. April Labrador. 2007. Adviser: Prof. Teresita M. A study entitled 'Supplementation of Fresh Oregano (Coleus aromaticus Benth.) Leaf Extract in the Drinking Water of Male Broilers" was conducted at the Production Project of the Department of Animal Science of Cavite State University, Indang, Cavite from July 06 to August 12, 2006. The study was undertaken to determine the effect of fresh oregano leaf extract on broilers in terms of body weight, feed consumption, feed conversion efficiency and meat acceptability and to determine the level of fresh extract most beneficial to broilers. Results of the study revealed that supplementation of fresh oregano leaf extract at varying levels did not have considerable effect on body weight, feed consumption and feed conversion efficiency of broilers. Being insignificant (P>0.05) in all aspects evaluated, the results of the sensory evaluation suggest that the panelists did not perceive any distinctive differences in the organoleptic traits of the samples. Three birds or 16.67 % mortality occurred in Treatment II during the third, fourth and fifth week of the experiment. The first mortality was due to the extremely cold weather while the second and third mortalities were due to a noticeable incidence of diarrhea in all the birds under all treatments as manifested in their watery dung. The highest production cost was incurred in Treatment III (Php 1724.44) while the lowest was recorded in Treatment II (Php 1699.11). The total return, on the other hand, was highest in Treatment IV (Php 2291.25) and lowest in Treatment H (Php 1872.00). Treatment IV turned out to be the most efficient because it generated a higher net income compared to the treatments. Treatment II incurred the lowest production cost considering a mortality of 16.67%, hence, the lowest income. Supplementation of fresh oregano leaf extract mixed in drinking water did not influence the body weight, feed consumption, feed conversion and meat acceptability of the broilers. Furthermore, the amount of fresh oregano leaf extract most suitable for broiler production was not accurately determined, since the amounts used in the study failed to influence the growth performance of the birds.
