Clitoria ternatea Extract as Natural Antibiotic Growth Promoter (AGP) on Broiler Concerning Carcass Quality and Intestine Morphometric

Background: This study aims to ascertain the optimal dose of Clitoria ternatea extract in relation to the quality of broiler carcasses and intestinal morphometrics. Methods: The Clitoria ternatea extract was applied in this study in different doses, where control, 4 ml, 6 ml, 8 ml, and 10 ml per litre of drinking water at weekly intervals in broilers to know the effect on carcass quality and intestine morphometrics. Statistical Tool for Agricultural Research (STAR) Software/STAR was used to analyze the data Using the corrplot function of the corrplot package from RStudio 4.2.2. Result: The results of variance analysis showed that the Clitoria ternatea extract treatment had a very significant effect (P less than 0.01) on Thigh Meat Cholesterol (TMC), Breast Meat Fat (BMF), low-density lipoprotein (LDL) of carcass broiler, and intestinal weight. In correlation, HDL Blood is positively correlated with intestinal weight (r=0.59) and blood cholesterol with LDL blood (r=0.77). The other parameters are positively correlated, such as abdominal fat is positively correlated with blood cholesterol, breast meat fat, and thigh meat cholesterol, where thigh meat cholesterol is positively correlated with breast meat cholesterol, breast meat fat is positively correlated with blood cholesterol and LDL blood, and these two parameters are positively correlated also with breast meat cholesterol and thigh meat fat. It can be concluded that Clitoria ternatea extract, as a natural antibiotic growth promoter for broilers, can improve the quality of broiler carcasses but does not have a substantial effect or correlation with intestine morphometrics.
