Studied were a total of 52 samples of forage mixtures prior to and after pelleting from three forage plants in this country, in terms of total bacterial count and the relative share of coli bacteria and Salmonellae. Two experiments were layed out under productional conditions for peletting a forage mixture at 92-94 degrees C being contaminated with Salmonella bacteria at the rate of 10(3) and 10(2) per gram of mixture. Results showed that pelleting processes reduce both the total bacterial count and the coli and Salmonella counts, the microbial cells being in an anabiotic status. It is suggested to adopt forage pelleting as a method to render harmless Salmonella-contaminated forages provided the count of Salmonella organisms does not exceed 10(2) per gram of forage. Pelleting should be carried out at 92-94 degrees C. This is to be routinely practised until the problem of forage decontamination is solved by other means.
对该国三种饲草植物制粒前后的52份饲草混合物样本进行了研究，涉及细菌总数以及大肠杆菌和沙门氏菌的相对占比。在生产条件下进行了两项实验，以92 - 94摄氏度对被沙门氏菌以每克混合物10³和10²的比例污染的饲草混合物进行制粒。结果表明，制粒过程会降低细菌总数以及大肠杆菌和沙门氏菌的数量，微生物细胞处于无生命状态。建议采用饲草制粒作为一种使受沙门氏菌污染的饲草无害化的方法，前提是沙门氏菌生物体的数量不超过每克饲草10²。制粒应在92 - 94摄氏度下进行。在通过其他方法解决饲草去污问题之前，应常规进行此操作。
