Problems solved by technology

Light grazing causes waste of pasture resources, while heavy grazing causes pasture degradation
In recent years, in order to protect the pastures, raising sheep in houses has become a trend, but raising sheep in houses will not only increase the cost of the breeder, but also cause a huge waste of existing pasture resources, indirectly reduce the productivity of pastures, and at the same time, the mutton produced by house feeding Strong smell, affecting consumption level
[0009] However, the prior art has the following defects: 1) it mostly focuses on the growth and development of livestock, such as body weight; 2) the detection index of meat quality research is relatively single, and most of them are the determination of nutrients in meat, which cannot fully reflect the quality of meat; 3) grazing

[0026] 1.1 Test time and place

[0027] The breeding experiment was carried out in the Siziwangqi Experimental Base of the Inner Mongolia Academy of Agriculture and Animal Husbandry Sciences from July to October 2009. The test base is located in the southeast of Siziwang Banner, Ulanchabu City, Inner Mongolia, 132 kilometers away from Hohhot, in the desert grassland and agro-pastoral zone, covering an area of ​​34,600 mu, 90% natural grassland. The main forage species in this area are Pinus breviflora, Artemisia frigida, and Cryptocarpa. The soil is chestnut soil. The annual rainfall in this area is 220-160mm. Sunite sheep is an excellent local meat breed, which can adapt to the harsh local climate. It has the characteristics of strong adaptability, cold and drought resistance, rough feeding resistance, strong disease resistance, etc., and stro...

Abstract

The invention relates to a free range husbandry method for improving mutton quality, which comprises free range concentrate supplementary. In the invention, juvenile castrated male lambs in a growing and finishing period are taken as research objects, and different free range husbandry methods are used for reasonably using pasture resources and improving meat quality; and thus, the pastures are reasonably used, high-quality mutton production capacity is improved, the consumption level and capacity of people are promoted, the economic benefit of manufacturers and operators at different stages is improved, the common development of grass industry and sheep raising industry is promoted, and industrial development and environmental protection are coordinated and unified in a real sense.

Description

Technical field [0001] The invention relates to the field of animal husbandry, in particular to a grazing method for improving the quality of mutton. Background technique [0002] Grazing is the most important use of grassland. In the grazing ecosystem, grassland and herbivores must be organically combined to form a balance of grass-livestock system, otherwise it will affect the harmony between grassland and herbivores that live on grassland. Make the environment worse. In recent years, due to the increasingly serious phenomenon of grassland "three modernizations", the area of ​​grassland is declining, and the degree of grassland desertification is increasing. The establishment of a reasonable grazing system is imminent, and a time-limited grazing system has emerged. [0003] The so-called meat quality, broadly speaking, includes the four aspects of meat's sensory quality, processing quality, nutritional value and hygienic quality. Among them, sensory quality is the most importan...
