Abstract: Bay leaves contain flavonoid active compounds including quercetine and fluoretine having antioxidative and antimicrobial properties.
Bay leaves can be given as feed additive to improve body metabolism in animals.
This study was aimed at assessing the effects of the inclusion of bay leaf solution in drinking water on the performance and carcass quality of male MA ducks.
Seventy-two male one-day-old MA ducks were allocated into battery cages .

INTRODUCTION
The crossbreeding of mojosari and alabio ducks has been conducted in Indonesian Research Institute for Animal Production.

Male MA duck, also known as king MA, is a superior meat producer with excellent reproductive properties (Laihad et al.
, 2.
King MA ducks are found to have faster growth rate and their meat is thicker, tenderer, more tasteful, and white in color.
These ducks are also more efficient in feed utilization, and vulnerable to diseases and At the age of 6 weeks.
MA ducks were found to have 1370 g body weight with a carcass percentage of 62.

METHODS
The study was conducted at the Poultry Farm of Department of Animal Husbandry.

LDS was prepared by boiling 100 g bay leaves in 2 liters of water for 20 minutes.
Boiled LDS was filtered and cooled before it was mixed with drinking water.
RESULTS AND DISCUSSION
Mesurements on feed intake, body weight gain, and feed conversion ratio were taken within the 8-week experimental period.
Means of performance of male MA ducks given drinking water containing LDS are listed in Table 1.

It was shown that the inclusion of bay leaf solution of various levels in drinking water of male MA ducks aged 2-8 weeks did not significantly (P>0.

This indicated that in male MA ducks treated with 8% LDS inclusion in drinking water, flavonoids contained in LDS improved basal metabolism.
Result of this study was in line with the notion that in addition to binding serum lipid and modifying oxidized Low Density Lipoprotein Cholesterol (LDL), quercetine and fluoretine also function in improving basal metabolism.

This high drinking water intake was higher than that of other kinds of fowls as duck is a waterfowl requiring more water.
