Abstract:

An important foundational component of work for construction and improvement of a national ecological grass husbandry system is to construct a universal quality and safety index system, to evaluate the quality and safety level of forage products in various regions. In this study, under the conceptual framework of the driving forces-pressure-state-impact-response (DPSIR) model, based on published forage standards and related literature, the relevant indicators affecting the quality and safety of forage products were systematically identified, and 14 core indicators were selected. These were: per capita consumption of beef and mutton, the number of machinery items for livestock husbandry, the number of items of equipment for keeping produce fresh in storage, the annual sunshine duration, the annual precipitation, the crude protein content, the neutral detergent fiber content, the acid detergent fiber content, the dry matter digestibility, the annual yield or growth rate of beef, the annual yield growth rate of mutton, the total amount of beef and mutton, the number of regional regulations and standards, and the quality supervision. The analytic hierarchy process (AHP) was used to quantify the weight of each index. The weight of crude protein content was found to be the highest, followed by neutral and acid detergent fiber content, and the weight of the number of items of equipment for keeping produce fresh in storage was the smallest. Based on this evaluation index system, the quality and safety of natural forage products in Tongde County of Qinghai Province and Shandan County of Gansu Province was evaluated. It was found that the quality and safety of natural forage products in Tongde County was higher than in Shandan County, and the corresponding safety levels were Grade Ⅱ and Grade Ⅲ, respectively. The establishment of a quality and safety evaluation index system for forage products is expected to result in improvement of the quality and safety level of forage products. This initiative will therefore provide important scientific guidance for ensuring forage production practices will deliver high quality products to local animal industries.
