Application method of digestion and emission reduction functional compound preparation for grazing cattle in saline-alkali soil

By screening the optimal mixing ratio of Mongolian leek and Daphne odora, a granular compound preparation was prepared, which solved the problems of low digestibility and high methane emissions in cattle grazing on saline-alkali land. This achieved efficient utilization of 'toxic weeds' resources, reduced breeding costs, and improved digestibility and methane emission reduction effects.

AI Technical Summary

Technical Problem

Cattle grazing on saline-alkali land have low digestibility and high intestinal methane emissions. Traditional 'toxic weeds' resources have not been effectively utilized, and there is a lack of compound forage technology suitable for grazing scenarios.

Method used

The optimal mixing ratio of Mongolian leek and Daphne odora was screened through in vitro rumen fermentation experiments. A granular compound preparation was then prepared and fed to grazing cattle in saline-alkali land at a fixed dose. Combined with scientific formulation to mitigate risks and achieve resource utilization.

Benefits of technology

It significantly improves the dry matter digestibility and nitrogen utilization efficiency of cattle grazing in saline-alkali land, steadily reduces methane emissions, lowers breeding costs, is easy to operate, and is suitable for large-scale promotion.

Abstract

The invention relates to the field of pasturing livestock nutrition and feed resource development, and particularly discloses an application method of a digestion and emission reduction functional composite preparation for pasturing cattle in saline-alkali soil, and the application method comprises the following steps: S1, selecting Allium mongolicum and Stellera chamaejasme as raw materials, and screening an optimal mixing ratio through in vitro rumen fermentation; s2, preparing a granular composite preparation according to the optimal proportion; s3, supplementary feeding is conducted on the saline-alkali land grazing cattle according to the fixed dosage. The method solves the problems of low digestibility and high methane emission of saline-alkali soil grazing cattle due to ingestion of low-quality forage grass, and solves the technical gaps that Allium mongolicum and Stellera chamaejasme are wasted as traditional toxic weed resources, and single grass seeds are difficult to synergistically realize digestion promotion and methane emission reduction, improves the digestibility of saline-alkali soil grazing cattle and nitrogen utilization efficiency, and improves the economic benefit of the saline-alkali soil grazing cattle. Methane emission is synchronously reduced, toxic weeds are converted into functional indigenous grass, the feed source is expanded, the breeding cost is reduced, the technology adapts to the grazing scene, operation is easy and convenient, and large-scale application and popularization are easy.
