Embodiment 1

[0031] Embodiment 1 basic diet

[0032] The composition of the basal ration used in the embodiment of the present invention is shown in Table 1, wherein the corn silage is a coarse material, and the rest are concentrated materials.

[0033] Table 1 Composition of basal diet

[0034] feed ingredients

[0035] The nutritional levels of the basal diets are shown in Table 2.

[0036] Table 2 Nutrient level of basal diet

[0037] nutritional level

[0038] Mix the components of the concentrate evenly in proportion and set aside.

Embodiment 2

[0039] Example 2 Sheep Diets Containing Different Levels of Licorice Extract

[0040] Add 1000mg / kg, 2000mg / g, 3000mg / kg, 4000mg / kg of licorice extract to the basal diet prepared in Example 1, respectively. Because the basic ration for sheep consists of concentrate and roughage, the conventional method is to stir the additive into the concentrate. Concentrate accounts for the ratio of 50% in the basal diet that embodiment 1 makes, therefore in the concentrate of basal diet, add the Radix Glycyrrhizae extract of 2000mg / kg, 4000mg / kg, 6000mg / kg, 8000mg / kg content, The basal diets with licorice extract content of 1000mg / kg, 2000mg / kg, 3000mg / kg and 4000mg / kg can be prepared.

Embodiment 3

[0042] 1 Test method

[0043] The experiment was carried out at Nuanquan Farm in Ningxia. Select 50 weaned Tan sheep male lambs of the same strain, four months old, similar in weight, and healthy, and randomly divide them into a control group and four test groups for feeding experiments. Example 1), test groups 1, 2, 3, and 4 were fed with 1000mg / kg, 2000mg / kg, 3000mg / kg, 4000mg / kg licorice extract in the basal diet respectively (see Example 2) . During the whole period of the experiment, the conventional feeding management was adopted, and the animals were fed in a single pen and fed in the morning and evening. The feeding method is according to the conventional feeding method, first coarse material and then concentrated material, and free drinking water. The test sheep were slaughtered from weaning to fattening, and the longissimus dorsi muscle was taken for analysis to determine the antioxidant capacity and drip loss.

Abstract

The invention relates to application of a licorice extract as an additive agent of mutton daily ration for reducing mutton drip loss. According to the invention, the licorice extract which is highly matched with main mutton producing area of China is added in the mutton daily ration, so that the oxidation resistance of the mutton can be improved from the daily ration nutrition regulation perspective, the water retention performance of the mutton is improved, the mutton drip loss is reduced, therefore, the mutton quality is improved, and the product competitiveness is increased.

Description

technical field [0001] The invention relates to the field of sheep feeding methods, in particular to a diet control method for reducing drip loss of mutton. Background technique [0002] Muscle contains about 75% water, 20% protein, 5% fat, and a small amount of carbohydrates, vitamins and minerals. Among them, mutton has the characteristics of high protein content and low cholesterol content. It is a traditional food and medicine dual-purpose and nutritious meat food in my country, and it is also a good product for tonic in winter. [0003] During slaughter, storage, and processing, the water in muscle is easily lost. Muscle can bind water to a certain extent through its own physical form and chemical structure, which is called water retention. The size of the water system is often described by drip loss, which is the most important indicator to measure the quality of meat. Studies have reported that dripping loss in fresh meat is generally 1-3% (Offer et al., The struct...
