Effect of Different Natural Feed Additives Compared to Antibiotic on Lipid Profile of Broiler Chicks Under High Temperature

Abstract

This experiment was conducted to investigate the effect of two different medicinal plants, cumin (Cuminumcyminum), fenugreek (Trigonellafoenum-graecum) as natural feed additives with antibiotic (Doxystin)on the serum lipid profile of broiler chicks. One hundred and sixty, (one day-old) broiler chicks were randomly divided into six groups of similar mean weight, each with four replicates of ten chicks. The control group received broilers basal diet. For the other groups, the basal diet was supplemented with one of the following: the antibiotic (Doxystin) as 0.5% or one of the spices, C. cyminum, T. foenum-graecum as 2%.Serum lipid profile in the broiler chicks was affected as follows, total cholesterol concentration was significantly (P<0.05) decreased in all groups received spices diet compared to doxystin and control groups. Also there was significant (P<0.05) decrease in the serum LDL-C concentration of T.foenum-graecum treated groupcompared to doxystin and control groups. Also the HDL-C concentration showed significant (P<0.05) decrease in all experimental groups compared to the control group. Spices treatments resulted in significant decrease of the total cholesterol and the LDL-C fraction similar to antibiotic treated animals. This experiment concluded that C. cyminum, T. foenumgraecum could be used as promising hypocholesterolemicagents that can improve meat quality.
