Estimation of The Correlation Value of Body Weight and Linear Body Size of KUB Chickens Fed Fermented Cow Feces

Abstract

The purpose of this study was to estimate the correlation value of growth traits and linear body size of KUB chickens fed feed containing fermented cow feces such as body weight, shank length, chest circumference, back length, and wingspan of KUB chickens from 8 to 16 weeks of age. Forty-eight adult chickens were used as parents consisting of 8 males, and 40 females. From their AI mating, they produced 100 chicks as research materials. A completely Randomized Design with 4 treatments and 5 replications for each treatment was used in this study. A correlation analysis was carried out using Spearman correlation analysis to calculate the correlation value and error standard. All data obtained were analyzed using SPSS release 21 software. The results showed that KUB chickens that consumed feed containing fermented cow feces as much as 10% were able to produce body weight and linear body size that was better than other treatments. The estimated correlation value between body weight and linear body size of KUB chickens consuming fermented cow feces varied from very strong to very weak. For selection purposes, it can be carried out mainly on traits with high positive correlation values.
