Embodiment 1

[0033] Obtaining and identification of plant extracts

[0034] 1. Extraction and identification of hesperidin

[0035] Hesperidin was extracted by solvent extraction. The dried tangerine peel was crushed and passed through a 250-mesh separation sieve to extract the active ingredients. The samples were stored at -20°C for later use. The specific steps are: (1) Weigh 0.20g of sieved dried tangerine peel powder into a 25mL polytetrafluoroethylene-lined stainless steel reaction kettle, and add 60% of tangerine peel according to a material-to-liquid ratio of 70:1 (g:mL). (volume fraction) ethanol solution, hot solvent extraction was carried out at 120°C, and the extraction time was 45min. (2) Centrifuge at 4000 r / min for 5 min after extraction, remove ethanol by rotary evaporation immediately, and store the remaining samples in vacuum freezer for subsequent identification.

[0036]Identification of hesperidin High performance liquid chromatography (HPLC) was used to quantitative...

Embodiment 2

[0045] Test design

[0046] Using a completely randomized experimental design, 200 healthy white-feathered broiler (AA) broiler chicks with an average body weight of (44.65±1.45) g were selected and randomly divided into 4 groups, namely the control group (Con Group), the orange Peridin group (HesGroup), rosmarinic acid group (Ros-A Group) and hesperidin-rosmarinic acid group (Hes x Ros-A Group), 5 replicates each, 10 chickens per replicate, There was no significant difference in body weight among the groups (P>0.05). Each replicate was placed in the same cage (0.9m x 0.6m). The basal diet adopts corn-soybean meal type diet, and is formulated into powdered compound diet with reference to "Standard for Chicken Feeding" (NY / T 33-2004). The control group was fed the basal diet, the hesperidin group was fed the basal diet + 60 mg / kg hesperidin preparation, the rosmarinic acid group was fed the basal diet + 30 mg / kg rosmarinic acid preparation, The hesperidin-rosmarinic acid gro...

Embodiment 3

[0048] Determination of growth performance indicators

[0049] At the beginning of the experiment, the initial body weight of 1-day-old broilers was weighed in each replicate and recorded. During the test period, at 21 and 42 days of age, the body weight of the broilers was measured with each repetition as a unit after fasting for 3 hours. The weight ratio is used to evaluate the effect of hesperidin-rosmarinic acid improving meat quality preparation on various growth performance indicators of broilers. The results are shown in Table 1.

[0050] Table 1 Effects of hesperidin preparations, rosmarinic acid preparations and hesperidin-rosmarinic acid preparations for improving meat quality in diets on the growth performance of broilers

[0051]

[0052] The growth performance results of broilers in the control group, hesperidin group, rosmarinic acid group, and hesperidin-rosmarinic acid group are shown in Table 1: Compared with the control group, the rosmarinic acid preparat...

Abstract

The invention discloses a biological agent for improving meat quality and a preparation method and application thereof, and the biological agent comprises hesperidin and rosmarinic acid in a mass ratio of (1-4): (1-2). The preparation method of the biological agent for improving the meat quality specifically comprises the following steps: (1) extracting hesperidin; (2) extraction of rosmarinic acid; (3) preparing an extract application solution; the combined preparation of hesperidin and rosmarinic acid is small in additive amount, high in activity and low in cost, improves the meat quality of broilers, improves the immunity of the body while enhancing the oxidation resistance of the body, promotes breast muscle deposition of the broilers, improves the nutrient content and proportion of muscles, and improves the quality of the broilers. The glucose utilization efficiency of the body is enhanced, meanwhile, the lipid synthesis and decomposition process of the body is promoted, and nutrient substances in muscles, especially the content and proportion of fatty acid can be improved.

Description

technical field [0001] The invention belongs to plant extracts, and in particular relates to a biological preparation for improving meat quality, a preparation method and application thereof. Background technique [0002] With high nutritional value, low fat content and ease of cooking, chicken is one of the main commodities in China's meat consumption market. With the continuous improvement of living standards, increasing the production capacity of high-quality poultry meat is also an important measure to meet the rigid needs of consumers. However, the broiler chickens in the intensive breeding mode have a fast growth rate and a short growth cycle, the chicken quality is difficult to reach the level of high-quality poultry, and the broilers in high-density cages are in a state of stress for a long time, which not only reduces the growth performance of the broilers, but may also affect the broiler chickens. health has an impact. In the past, farmers usually added antibioti...
