Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of organic trace element complex package, in particular to a complex package for improving broiler chicken wooden meat and a preparation method and application thereof. BACKGROUND

[0002] Chicken meat quality is one of the most concerned problems in broiler industry, which affects the economic benefits of broiler, and good chicken meat quality is a performance of broiler health and a key to whether the chicken meat can be accepted by breeders and consumers.

[0003] Wooden meat is a new type of broiler muscle abnormality problem, which mainly occurs on the breast muscle, and is a late stage of white striped meat. Wooden meat is characterized by ridge-shaped protrusions on the surface of the breast muscle, and the texture is hard. The hardening of the upper part of the breast muscle is usually the first to occur, and then spreads to the tail of the breast muscle. In the later stage, the surface of the breast muscle is also accompanied by tissue fluid exudation and blood spots, and the sensory is dull. In recent years, the rapid growth of broiler breeding and the excessive pursuit of feed to meat ratio in China have led to a shortened growth period of broiler, insufficient muscle composition deposition, and an increased incidence of wooden meat. According to relevant data, the incidence of wooden meat in China has reached as high as 18.33%. Oxidative stress, hypoxia and their interaction are the triggering factors of wooden meat. In addition, broiler metabolic abnormalities, inflammatory response, excessive growth rate and high meat yield can all increase the incidence of wooden meat.

[0004] At present, most of the researches mainly focus on the mechanism of wooden meat, and there is a lack of systematic and targeted measures to solve the problem of wooden meat in broiler. In actual production, more attention is paid to single nutritional regulation: such as adding vitamin C, arginine, inositol or reducing the fat content of the diet for prevention; secondly, the physicochemical properties of the chicken meat that has formed lesions are optimized to improve the meat quality and processing characteristics. Both of them do not fundamentally solve the problem of wooden meat in broiler. SUMMARY

[0035] The nutritional levels are calculated values.

[0036] Raising management: The experiment used full-closed cage raising, arranged in three layers. The temperature in the shed was controlled at 34 ℃ for 1-day-old broilers, then decreased by 1 ℃ every 2 days until the temperature was maintained at 21 ℃. The relative humidity in the shed was controlled at 65%-70% in the first week, and then decreased to 50%-65% and maintained unchanged in the second and third weeks. Incandescent lamps with a light intensity of 10-15 lx were used in the shed, with 23 h of light and 1 h of darkness in the first week, 20 h of light and 4 h of darkness in the second and fourth weeks, and then 23 h of light and 1 h of darkness until the end of the experiment; the light was uniform on each layer. The broilers were allowed to freely eat and drink water using nipple waterers, and daily management was carried out according to the requirements of the chicken farm.

[0037] Test period: 42 days.

[0038] 2. Detection index Average daily feed intake (ADFI), average daily gain (ADG), feed to gain ratio (F / G), mortality rate, wooden meat, etc.

[0039] 3. Results The experimental data were preliminarily arranged using Excel (2013), and independent sample t-test was performed using SPSS 17.0, with the results expressed as mean ± standard error.

[0040] The results of the production performance test are shown in Table 2. It can be seen that there was no significant difference in the body weight, ADFI and mortality rate of white-feathered broilers at 42 days of age between the groups with and without the addition of the compound package in the diet ( P >0.05); the ADG of the test group had a tendency to increase compared to the control group ( P <0.10), with an increase of 2.45 g / d; the F / G of the test group was significantly lower than that of the control group ( P <0.10), with a decrease of 0.06.

[0042] Note: The same row data with different capital letters indicate extremely significant difference ( P <0.01), different small letters indicate significant difference ( P <0.05), and no letters indicate no significant differenceP >0.05), same below.

[0043] The results of the wooden meat test are shown in Table 3. It can be seen that the proportion of wooden meat of the white-feathered broiler chickens in the test group at 21 days of age was significantly reduced compared with the control group (P < 0.05), and was reduced by 41.40%; the proportion of wooden meat of the white-feathered broiler chickens in the test group at 42 days of age was extremely significantly lower than that in the control group (P < 0.01), and was reduced by 86.63% to below 2%. The effect of feeding the compound package on improving wooden meat is shown in Table 3. P P Figure 1

[0044] Table 3. Effect of the compound package on wooden meat of AA broiler chickens in effect example 1

[0045] It can be seen from effect example 1 that adding the compound package of the application to the basic diet has a trend of improving the average daily weight gain of broiler chickens, significantly reduces the feed conversion ratio, and extremely significantly reduces the incidence of wooden meat of broiler chickens. It can be inferred that the growth-promoting and meat-improving effects may be related to the chelation of humic acid with trace elements, the improvement of the absorption rate of trace elements, the activation of humic acid to improve the absorption of feed, antibacterial and anti-inflammatory, astringent and antidiarrheal, treatment of nutritional diarrhea, maintenance of intestinal health, trace element antioxidant stress, and improvement of the resistance of broiler chickens.

[0046] Therefore, the compound package of the application is a green and efficient feed additive, has a significant effect on improving wooden meat of broiler chickens, and has a broad application prospect.​​​
