ABSTRACT

Todeterminethe correlation betweenthe leveloffeed energyto bodyweightand meat

quality of semi intensive France muscovy duck, the authors of this article research on

the experimental arrangement adopted in 1050 France meat Muscovy duck, divided

5 batches, each batch of 70 birds, 35 males, 35 females, repeat 3 times, with densities

energy decreases from 1 to5:290012800/2700/2600/2500 kcal/kg 1-3 weeks period,

3050/2950/2850/2750/2650 kcal/kg 4:7 weeks period; 3150/3050/2950/2850/2750

kcal/kg period 8-12 weeks of age, all batches are the same levels of crude protein at 3

correspondin g periods w as 1 8/ 1 6/ 150/o:

Results showed that lowering the energy density of feed intake, the growth of

France Muscovy duck down, live weight at 12 weeks of age was highest in plot I

(3587.26 g), the lowest in plot V (3142.55 g), density energies of feed did not affect

the protein ratio of meat, but lipid rations of meat increased proportionally to the

energy in the diet. The relationship between dietary energy levels with live weight

of France Muscovy duck were positively correlated and close. Correlation coefficient

between dietary metabolizable energy densitiEs and muscle'chemical composition

were mostly positive, the male is closer than that of female.

1. INTRODUCTION

Energy density of feeds affects performance and quality of poultry meat. However, the impact

of how each type of poultry farming in different conditions have not been fully studied. To find

out the correlation belween the .rergy levels in the diet with body weight and meat quality French

Muscovy duck keeping in semi intensive, we carried out this topic.

2. MATERIALS AND METHODS

21 Location

The experiment was conducted at the experimental farm in College of Agriculture and Forestry,

Thai Nguyen University, Viet Nam.

2.2 Methodology

The experiment was arranged in a subdivision method compared to ensure equitable principles

of variety, age, number, sexes, density, breeding methods and processes of care. The different

experimental factors such as the levels of energy.
