STUDY ON THE IMPACT OF CASSAVA LEAF MEAL ON THE PRODUCTIVITY AND QUALITY OF JAPANESE QUAIL IN THAI NGUYEN PROVINCE

Abstract

The study was conducted on 300 quails from 1 to 42 days of age, divided into two group, each group have 50 quails, repilcate 3 times (3 x 50 =150). The control group (CG) was feed base diet (BD); the experimental group (Exp) were feed the diet supplemented 0%; 2 % and 4 % cassava leaf meal in three periods of 1- 7; 8- 21 and 22-42 days of age, respectively. The Exp diet has the same level of metabolic energy and protein in comparison with BD. The result showed that: at 6 weeks of age, the live rate of CG was 90.67% and the Exp was 94.67%. The body weight of CG was 165.50 g and Exp was 177.50 g. Feed conversion ration/1 kg body weight gain of Exp was less than CG of 6.71%; the average dry matter and lipid of breast and leg muscle of Exp less than the CG but the protein it higher than the CG.
