Abstract:

The experiment was conducted to study the effects of plant additives (mulberry leaf powder,garlic powder and green tea powder) on content and composition of amino acids and fatty acids in muscle in Huiyang Bearded chicken.120 one hundred and twenty-day-old female chickens were randomly divided into 4 treatments,3 replicates per treatment,10 chickens per replicate.The different treatments were fed the following diets:Group Ⅰ,fedding basal diet + 2% green tea powder;Group Ⅱ,feeding basal diet + 4% mulberry leaf powder;Group Ⅲ,feeding basal diet + 1.5% garlic powder;Control group,feeding basal diet.After preliminary experiment for 7 days,the feeding trial lasted for 30 days.After the trial,10 chickens per treatment were selected to be slaughtered.100 g of meat from breast muscle of every individual from the slaughtered chickens was used to analyze the content and composition of fatty acids and amino acids by gas chromatography and automatic amino acid analyzer,respectively.The results showed that:①The plant additives had no effect on the composition of amino acids in muscle,but significantly improved the content of essential amino acid in muscle compared with the control group (P<0.05);②The plant additives had no effect on the composition of fatty acids in muscle,but significantly decreased content of the saturated fatty acids (P<0.05),while significantly improving percentage of polyunsaturated fatty acids in muscle compared with the control group.Overall,the plant additives could improve the meat quality by significantly improving the content of essential amino acid,percentage of polyunsaturated fatty acids in muscle,and significantly decreasing content of the saturated fatty acids in muscle.

Key words: plant additives; Huiyang Bearded chicken; amino acids; fatty acid
