Improving productivity in the animal feed industry is crucial to ensure proper nutrition for animals and the

quality of meat products, making it a vital sector for food security and the economy. The issue identified in the

research relates to productivity and efficiency limitations in animal feed plants, caused by inefficient processes,

waste, and extended changeover times, which affect the profitability and competitiveness of companies in the

sector. The proposed solution included the implementation of Lean tools such as 5S, Heijunka, and SMED to

optimize production processes, reduce changeover times, eliminate waste, and enhance operational efficiency

in animal feed plants. The results of this research showed significant improvements in the productivity of the

plant studied, with a 35% increase, a 73% reduction in changeover times, a 47% decrease in the production

cycle time, and a 98% increase in production schedule compliance. These indicators reflect the positive impact

of implementing Lean tools in the animal feed industry.
