Growth and Carcass Characteristics of Japanese Quail Taking Hibiscus sabdariffa Supplement in Diet.

Abstract

In pharmacology, roselle, krajeab or Hibiscus sabdariffa is a herb that the study has found that it can reduce fat in veins. The kajeab juice is a pro-health drink to reduce the blood thickness and help digestion. Krajeab or roselle fruits are harvested fresh and their calyces are used. In the study calyces were dried and made into a mixture of a supplementary diet for feeding Japanese quails to study their growth, the volume and the efficiency growth rate and their carcass characteristics. The quails were 5-13 weeks old and 400 male Japanese quails were used in the experiment. A completely randomized design (CRD) was used in 4 treatments and 5 replications in which 20 birds were used in each replication. Group 1 was the control group, a premixed diet was used; Group 2 a premixed diet with a mixture of 1.0 percent of roselle was used; Group 3 a premixed diet with a mixture of 3.0 per cent of roselle was used; Group 4 a premixed diet with a mixture of 5.0 percent of roselle was used. The data on the volume of food, the volume of water, and the weight of each quail was recorded weekly. The carcass characteristics of Japanese quails at the age of 13 weeks were recorded. The data analysis was done by IRRISTAT program. The results were as follows: When a roselle mixture as a supplementary diet at different levels for Japanese quails was used, they weighed lower that those in the control group but not significantly different. Besides, it has found that a roselle mixture as a supplementary diet at 1.0, 2.0 and 5.0 per cent affected the growth of Japanese quails when compared with those in the control group and was significantly different (p<0.01) and it also made the efficiency growth rate higher than those in the control group; the carcass characteristics were significantly different. When a roselle mixture at 1.0, 3.0 and 5.0 percent was used, it could reduce the abdominal fat that was less than those in the control group and was significantly different (p<0.01). The study on the color of the carcass characteristics has found that the color of chest, abdominal fat, heart and liver of Japanese quails that took a mixture of a supplementary diet at 1.0, 3.0 and 5.0 per cent was not significantly different. To sum up, roselle krajeab contain certain characters to reduce fat in veins in Japanese quails. This can be seen from all group of Japanese quails that accessed roselle krajeab would result low fat in veins if compare to those Japanese quails which were not and these showed distinguished statistical outcomes (p<0.01). Moreover, for the future purpose of study shall focus on hematology and cholesterol leves within blood in order to verify better results in reducing both for as well as choledterol levels.
