Effects of Combination of Plant Essential Oil and Benzoic Acid on Growth Performance,Slaughter Performance,Meat Quality and Muscle Odor Components,Texture Characteristics and Antioxidant Capacity of Huaibei Partridge Chickens
This experiment was conducted to study the effects of combination of plant essential oil and benzoic acid on growth performance,slaughter performance,meat quality and muscle odor components,texture char-acteristics and antioxidant capacity of Huaibei partridge chickens.A total of 360 one-day-old male Huaibei par-tridge chickens were randomly divided into 4 groups with 6 replicates per group and 15 chickens per replicate.Chickens in the control group(CON group)were fed a basal diet,and others in experiment groups were fed basal diets supplemented with 300 mg/kg plant essential oil compounds(EO group),2 000 mg/kg benzoic acid(BA group)and 300 mg/kg plant essential oil compounds+2 000 mg/kg benzoic acid(EO+BA group),respectively.The experiment lasted for 90 days.The results showed as follows:1)dietary plant essential oil significantly decreased the feed to gain ratio(F/G)(P＜0.05).Dietary benzoic acid significantly increased the final body weight(FBW)and average daily gain(ADG),and significantly decreased the F/G(P＜0.05).Dietary plant essential oil and benzoic acid had significant interaction on FBW,ADG,average daily feed in-take(ADFI)and F/G(P＜0.05).2)Dietary plant essential oil had no significant effects on slaughter per-formance(P＞0.05).Dietary benzoic acid significantly increased the dressing percentage,semi-eviscerated percentage and eviscerated percentage(P＜0.05).Dietary plant essential oil and benzoic acid had no interaction on slaughter performance(P＞0.05).3)Dietary plant essential oil significantly decreased the pH of leg muscle(P＜0.05).Dietary benzoic acid significantly decreased the pH of breast muscle(P＜0.05).Dietary plant es-sential oil and benzoic acid had significant interaction on pH,drip loss rate and shear force of breast muscle(P＜0.05).4)Dietary plant essential oil had no significant effects on texture characteristics of breast muscle and leg(P＞0.05).Dietary benzoic acid significantly increased the gumminess of leg muscle(P＜0.05).Diet-ary plant essential oil and benzoic acid had significant interaction on the hardness of breast muscle and elastic-ity,gumminess and chewiness of leg muscle(P＜0.05).5)Dietary plant essential oil increased the contribu-tion ratio of inorganic sulfides to principal component 1(PC1)of breast muscle and leg muscle,and increased the contribution ratio of organic sulfides to principal component 2(PC2)of breast muscle and leg muscle.Di-etary benzoic acid increased the contribution ratio of inorganic sulfides to PC1 of leg muscle,and increased the contribution ratio of organic sulfides to PC2 of breast muscle and leg muscle.Dietary plant essential oil and benzoic acid increased the contribution ratio of inorganic sulfides to PCI of leg muscle,increased the contribu-tion ratio of short-chain alkanes to PC2 of breast muscle,and increased the contribution ratio of organic sulfides to PC2 of leg muscle.6)Dietary plant essential oil significantly increased activity of catalase(CAT)in breast muscle and activity of glutathione peroxidase(GSH-Px)in leg muscle(P＜0.05).Dietary benzoic acid had no significant effects on antioxidant indexes of breast muscle and leg muscle(P＞0.05).Dietary plant essential oil and benzoic acid had significant interaction on activity of CAT in breast muscle and leg muscle(P＜0.05).In conclusion,dietary combination of plant essential oil and benzoic acid can increase growth performance,im-prove odor components and increase muscle antioxidant capacity of Huaibei partridge chickens.[Chinese Jour-nal of Animal Nutrition,2024,36(1):295-311]
