As an added feature of Asian Agribiz’s 2022 Pig Feed Quality Conference, Kemin Industries sponsored a deep dive tutorial on protecting against ASF beyond the mill. Below are some highlights.
Identifying significant ASF risks in feedmills
Traffic and material inputs are key factors to assess when identifying virus contamination in feedmills. “When we talk about traffic, we must be careful about the people and vehicles going in and out. This is especially true for people who enter the production area, which should be kept strictly clean,” said Alex De Leon, Head of Technical Services, Kemin Animal Nutrition and Health, Asia Pacific. The risks from input materials can come from their packaging. “When there is ASF contamination in your feedmill, the best places to check for it are the material storage bins, boots, and finished feed,” he advised.
Critical steps in material testing to ensure feed safety
Testing materials starts from the material supplier. Dr De Leon said feed producers should conduct audits on how suppliers handle and transport materials. In feedmills, processes should be in place for proper sampling and testing to identify the targeted pathogens. The most critical step is monitoring and measuring the raw materials and the finished feeds in the plant, he added.
How to protect farms from ASF recontamination
Preventing ASF recontamination must start from the feedmill. “Once the feedmill is contaminated, it will stay contaminated,” said Dr De Leon. He pointed out that the transportation of feed also poses contamination risks. Proper cleaning of the surfaces of the feedmill and the trucks will help producers reduce the risk of pathogens being introduced to customer farms. He emphasized that formaldehyde and/or organic acids are effective tools to mitigate ASF pathogens in feedmills and farms.
