Wherein, the following experiments are carried out to prove that:
540 healthy 28-day-old fast-growing yellow-feathered broilers with similar body weight are selected in the test, and are randomly divided into 3 groups according to the body weight, each group has 6 repetitions, and each repetition has 30 chickens. Wherein the control group was fed a corn-soybean meal type basal diet without any antibiotics, and the test groups were supplemented with 10mg/kg of zinc bacitracin (antibiotic group) and 10mg/kg of citrus extract (citrus extract group), respectively, to the basal diet. The basic diet is prepared according to NRC (1994) and combined with national agriculture 2004) and is prepared into granular feed. Test period 35 d. The basal diet composition and nutritional levels are shown in table 1.
The feeding test was carried out in the animal science research institute of Guangdong province academy of agricultural sciences. All test chickens were raised on a 4-layer three-dimensional net and were fed with free food and water. During the test period, natural illumination is adopted, and additional illumination is not supplemented. Others were raised and immunized according to conventional feeding and immunization procedures. Daily feed intake was recorded during the trial and the health of the test chickens was observed.
At the age of 63 days, after fasting for 12h, 2 broilers with the weight close to the average weight were randomly selected for each repetition. Weighing the live weight of each chicken before slaughtering, then bleeding and killing the neck vein, removing the feather, recording the slaughtered weight, then dissecting, and taking the breast muscle, leg muscle, abdominal fat and the like for measuring the carcass performance indexes of the broiler chicken. The internal organs were rapidly isolated and the weight of spleen, thymus, bursa of fabricius and liver was recorded. The left dorsal pectoral muscle was used to determine the meat quality and antioxidant index.
The experimental results are as follows:
the influence of the citrus extract added into the feed on the organ index of yellow-feathered broilers is as follows:
as can be seen from Table 2, compared with the control group and the antibiotic group, the spleen index of the broiler chickens in the citrus extract group is increased by 56.25% (P < 0.05); compared with a control group, the broiler liver index of the citrus extract group is improved by 21.15% (P is less than 0.05); no significant difference was found between the broiler thymus index and the bursal index among the groups (P > 0.05).
The influence of the citrus extract added into the feed on the slaughtering performance of yellow-feathered broilers is as follows:
as can be seen from table 3, compared with the control group, the leg muscle rate and the breast muscle rate of the broiler chickens in the citrus extract group were respectively increased by 16.40% and 21.18% (P <0.05), and the muscle rate of the broiler chickens in the antibiotic group was increased by dried flank meat% (P < 0.05). No significant difference exists among the groups in the slaughtering rate, the half-bore rate, the full-bore rate and the abdominal fat rate (P is more than 0.05).
The feed is added with the citrus extract to influence the meat quality and muscle oxidation resistance index of yellow-feathered broilers:
as can be seen from table 4, compared with the control group, the alpha value of dried flank meat muscle at 45min after slaughtering of the broiler chickens in the citrus extract group is increased by 11.21% (P <0.05), and the L value and the b value are respectively reduced by 3.87% and 18.95% (P < 0.05); the pectoral b' value of 45min after slaughtering of the broiler chickens in the antibiotic group is reduced by 16.77% (P < 0.05). Compared with the antibiotic group, the L value of pectoralis muscle of the citrus extract group is reduced by 3.74 percent (P <0.05) 45min after the broiler chicken is slaughtered. No significant difference was observed between groups at 45min dried flank meat muscle pH after slaughter of broiler chickens (P >0.05), and at 24h dried flank meat muscle pH after slaughter, meat color, drip loss and tenderness (P > 0.05).
As can be seen from table 5, the broiler muscle GSHPx activity in the citrus extract group was increased by 15.57% and 32.03%, respectively (P <0.01), compared to the control group and the antibiotic group. No significant difference exists between the activities of broiler chicken muscles T-A0C and T-S0D and the content of MDA (P is more than 0.05).
To summarize: in conclusion, under the test conditions, the feed added with 10mg/kg of the citrus extract can improve the slaughtering performance of yellow-feathered broilers, enhance the immunity of organisms, improve the meat quality and improve the oxidation resistance of muscles, and the improvement effect is better than that of the feed added with 10mg/kg of bacitracin zinc.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
