Example Embodiment

[0031] Example 1 Basic diet

[0032] The composition of the basal diet used in the examples of the present invention is shown in Table 1. Among them, corn silage is coarse feed, and the rest is concentrated feed.

[0033] Table 1 Basic diet composition

[0034] Feed ingredients

[0035] The nutritional level of the basal diet is shown in Table 2.

[0036] Table 2 Nutritional level of basal diet

[0037] Nutritional level

[0038] The components of the concentrate are mixed uniformly in proportions and set aside.

Example Embodiment

[0039] Example 2 Sheep diets with different levels of licorice extract

[0040] The basal diet prepared in Example 1 was supplemented with licorice extract with a content of 1000 mg / kg, 2000 mg / g, 3000 mg / kg, and 4000 mg / kg, respectively. Because the basic diet of sheep includes concentrate and coarse meal, the conventional method is generally to mix the additives into the concentrate. In the basal diet prepared in Example 1, the concentrate accounts for 50% of the proportion. Therefore, 2000mg / kg, 4000mg / kg, 6000mg / kg, 8000mg / kg of licorice extract is added to the concentrate of the basal diet. The basal diets with licorice extract content of 1000mg / kg, 2000mg / kg, 3000mg / kg and 4000mg / kg can be prepared.

Example Embodiment

[0041] Example 3

[0042] 1 Test method

[0043] The experiment was conducted in Ningxia Nuanquan Farm. Select 50 healthy weaning tan sheep lambs of the same strain, four months old, similar weight, and randomly divided into a control group and four test groups for feeding experiments. The control group was fed a basic diet without licorice extract (see Example 1) The test group one, two, three, and four were fed diets supplemented with 1000mg / kg, 2000mg / kg, 3000mg / kg, 4000mg / kg licorice extract in the basic diet (see Example 2) . During the whole trial period, conventional feeding management was adopted, single pen feeding, and feeding in morning and evening. The feeding method is in accordance with the conventional feeding method, first coarse feed and then refined feed, free drinking water. The test sheep were slaughtered from weaning to the end of 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...
