This study aims to determine the morphometrics of 3 age groups on the consumption of feed with the same nutrition and on growth. The material used was 50 male fighting cocks which were separated based on 3 age categories, namely 6- 8 months, 9-12 months, 13-30 months. The research method used is descriptive analysis in the form of mean, standard deviation, coefficient of variance, correlation test and followed by t-test. Data collection was done by direct observation and measurement of quantitative properties based on the observed parameters. The results of this study show a description of the qualitative and quantitative characteristics of male fighting cocks based on 3 very diverse age categories and have different characteristics ranging from eye color, feather color and shank color, then from the results of quantitative analysis of maxilla length, wing length, chest length , chest width, femur length, tibia length, shank length, third toe length and shank circumference, had different averages and correlated from high to moderate. From the results of the t-test on feed and morphometrics, there were several significant differences between maxilla length, wing length, chest length, chest width, femur length, and shank circumference (P<0.05) while the tibia length, shank length, and the length of the third toe showed no significant difference (P> 0.05). Then the results of the t-test showed that the feed given to the body weight of the fighting cocks had a significant difference from feeding the 1st week to the 6th week (P<0.05). Differences can occur due to several factors, namely the content of food substances in the feed, especially the energy and protein content, and can be influenced by environmental factors, genetics, maintenance management, drug administration, vitamins, herbal herbs and environmental temperature. Keywords: Fighting cock, qualitative nature, quantitative nature, feed.
