Method for improving quality of mutton by using stems and leaves of liquorice

Abstract

A method for improving the quality of mutton by using stems and leaves of liquorice comprises the following steps of (1) mixing the following ingredients in percentage by weight: 39%-40% of alfalfa, 19%-21% of withered and yellow liquorice stem and leaf grass meal, 29%-30% of corn, 4.0%-3.9% of cotton seed meal, 3.8%-3.9% of sunflower seed meal, 1.0%-1.1% of salt and 1.0%-1.1% of additives manually or by using a TMR (total mixed ration) machine or preparing the ingredients into total mixed ration particles on the basis of dry matters; and (2) feeding mutton sheep by using the daily ration mixed in the step (1) every morning and every evening at intervals of 10-11 hours. The feeding period is not shorter than 50 days, the content of the dry matters in the liquorice stem and leaf grass meal in the daily ration of the mutton sheep reaches 345-377 grams per day, and the mutton sheep freely eat the ration and freely drink water in the feeding period. By the method, the cholesterol content of the mutton can be reduced obviously, and the content of inosine monophosphate, amino acids and unsaturated fatty acids is increased, so that the quality of the mutton is improved.

Description

technical field [0001] The invention relates to a method for improving the quality of mutton, in particular to a method for improving the quality of mutton by using licorice stems and leaves with characteristics of Chinese medicinal materials. Background technique [0002] Licorice has excellent characteristics such as cold resistance, heat resistance, drought resistance, and saline-alkali resistance. It has strong fitness and vigorous vitality. It is one of the important plant resources in arid and semi-arid areas. As the aerial part of licorice, licorice stems and leaves have high crude protein and crude fat content and low crude fiber content in the vegetative stage, and contain a variety of amino acids, major elements and trace elements. The feeding effect is similar to that of alfalfa, and the output remuneration Slightly higher than alfalfa, it is an excellent leguminous forage with dual functions that other forages do not have, and its application prospects are very p...

Problems solved by technology

[0003] At present, prior art Feng Jianzhong etc., research shows in the "Discussion on Utilizing Licorice Resources to Develop Animal Husbandry Production" published in the 2nd issue of 1995 "Environment and Resources in Arid Areas" that feed with 20% licorice seedling powder+20% alfalfa powder The weight gain effect of feeding 4-month-old Tan lambs is higher than that of 40% alfalfa powder group and 40% licorice seedling powder group, but there is no research on the improvement of mutton quality by licorice stems and leaves

Guo Tongjun et al. published "The Effects of Licorice Stems and Leafs Substituting Alfalfa on Milk Components and Blood Indexes of Dairy Cows" published in "Feed Research" in the 02 issue of 2013, which disclosed that 18% (dry matter basis) of licorice stems and leaves were added to the diet of Holstein dairy cows. The effect is similar to the same amount of alfalfa, and the blood cholesterol of the group fed with licorice stems and leaves increases by 9.54%, but there is no problem related to the improvement of meat quality with licorice stems and leaves

Xue Zhengfang, Shihezi University's 2004 master's thesis "Evaluation of Nutritional Value of Licorice Stems and Leaves and Research on Development and Utilization" discloses that on the basis of basic diets, each sheep is fed with 500g and 300g of licorice stems and leaves per day, and 42 It was found that the daily gain of the 500g and 300g licorice stem and leaf groups was 57.14g and 29.14g higher than that of the control group, and the total blood cholesterol content decreased by 1.2% to 8.43%. lamb quality problems
