Core Viewpoint - The grain-saving action in the livestock industry is crucial for high-quality development and strategic transformation regarding feed grain security, requiring both technological innovation and conceptual upgrades to shift from a "resource-consuming" model to a "high-efficiency and sustainable" model [1][5]. Group 1: Current Challenges in Livestock Industry - China's livestock industry consumes over 40% of total grain consumption, with significant waste due to traditional farming methods [2]. - Issues include high feed wastage rates from manual feeding, imbalanced nutrient formulations, and low utilization of alternative feed resources such as crop residues and insect protein [2][3]. - The reliance on corn and soybeans for feed leads to increased costs and environmental pressures, necessitating the implementation of grain-saving actions [2]. Group 2: Measures for Grain Saving - The Ministry of Agriculture and Rural Affairs has introduced a plan focusing on three main measures: improving efficiency in grain use, increasing alternative feed sources, and optimizing feed structure [1][5]. - Technological empowerment is essential, including the promotion of precise feed formulation technologies and the development of smart feeding systems to enhance feeding accuracy [3][4]. - There is a push to diversify feed sources by utilizing non-grain feed resources such as microbial fermentation of crop residues and exploring the potential of insect and algae proteins [4]. Group 3: Structural Adjustments in Livestock Production - The livestock industry, primarily dominated by pig farming, needs to adjust its feed structure, particularly reducing the high feed-to-meat ratio compared to poultry and aquaculture [5]. - Continuous optimization of pig production capacity and promoting efficient meat poultry production are necessary to balance supply and demand [5]. - The industry should also focus on developing facility aquaculture and enhancing the supply capacity of aquatic products while promoting policies and technologies that support these transitions [5].
