Abstract


The aim of this study is to evaluate zootechnical and biochemical parameters in poultry farm after using a dietary exogenous enzymes. This study was conducted on a total of 7.400 chicks from Arbor Acres strain. They were divided into two groups, one received a basic diet (standard) not supplemented with enzymes as control throughout the rearing period and the other a diet supplemented with enzymes. Growth performance, feed efficiency and mortality were recorded at the end of each week. Results showed that the addition of the enzymes does not significantly improve body weight and feed conversion during the breeding period. However, the mortality rate was higher in the control group compared to supplemented with the enzymes. The diet based on exogenous enzymes decreased the level of serum glucose (1.75 g.L-1 vs 2,60 g.L-1), respectively for the control and experimental group). It increased not significantly, the levels of triglycerides (0,87 vs 0,53 g.L-1), HDL (0,79 vs 0,75 g.L-1), LDL (0,28 vs 0,16 g.L-1). Exogenous enzymes proved a positive effect on zootechnical parameters and serum glucose in Algerian broiler chicks.
