Free range husbandry method for improving mutton quality

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 main way of using grassland. In the grazing ecosystem, grassland and herbivores must be organically combined to form the balance of the grassland-animal system, otherwise it will affect the harmony between the grassland and the herbivores who live on the grassland. worsen the environment. In recent years, due to the increasingly serious phenomenon of "three modernizations" of grassland, the area of ​​grassland is decreasing, and the degree of desertification of grassland is increasing. It is imminent to establish a reasonable grazing system, and the time-limited grazing system came into being. [0003] The so-called meat quality, broadly speaking, includes four aspects: sensory quality, processing quality, nutritional value and hygienic quality of meat. Among them, the sensory qual...

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 The system takes the season as the change time point, and the seasonal grazing method is only changed according to the seasonal change, but the grazing is still all-day grazing (the grazing time is taken as the unit of day), and the grazing time is extensive and imprecise; There is no report on the relationship between growth performance and meat quality of Sunite sheep (a unique local breed in China)

[0010] Therefore, there are few studies on mutton in the prior art, and the most suitable grazing and feeding methods in arid and semi-arid pastures have not been obtained, and the impact of grazing and feeding methods on mutton quality, especially the short-chain fatty acids related to the smell of mutton, has not been found. Reports on the relationship between stearic acid and muscle fiber changes
