The use of antibiotics in agriculture has seen many changes over the last few years. Most notably, all medically important antibiotics for veterinary use can now only be obtained by prescription. These and other changes led to the reduction or elimination of antibiotics in animal feed. Antibiotics in feed has been used for decades and their use has shown very positive therapeutic effects, such as improved feed conversion, reduced morbidity, and less clinical and subclinical disease in Canadian livestock. With the new restrictions on antibiotic use, Canadian livestock industries are actively seeking alternatives to antibiotics to add to feed to act as 'growth/health promoters'. Proveta Nutrition, Ltd. has a product called GoldEdge+ that improved the number of eggs produced by layer chickens which suggests that it may positively impact their productivity and health. We will perform microbiological analyses to determine the minimum inhibitory concentration of GoldEdge+ needed to kill or inhibit the growth of field isolates of Escherichia coli, Salmonella Typhimurium, Salmonella Enteritidis, Streptococcus suis, Clostridium perfringens and Lawsonia intracellularis. The bacteria can infect poultry, pigs and cattle so information on GoldEdge+ antimicrobial activity on them may potentially impact several of Canada's livestock industries.

在过去几年中，抗生素在农业中的使用发生了许多变化。最值得注意的是，所有医学上重要的兽医用抗生素现在只能通过处方获得。这些和其他变化导致动物饲料中抗生素的减少或消除。在饲料中使用抗生素已经有几十年的历史，它们的使用显示出非常积极的治疗效果，例如提高饲料转化率，降低发病率，减少加拿大牲畜的临床和亚临床疾病。随着对抗生素使用的新限制，加拿大畜牧业正在积极寻求抗生素的替代品，以添加到饲料中，作为“生长/健康促进剂”。Proveta营养有限公司有一种名为GoldEdge+的产品，可以提高蛋鸡的产蛋量，这表明它可能对蛋鸡的生产力和健康产生积极影响。我们将进行微生物学分析，以确定GoldEdge+杀死或抑制大肠杆菌、鼠伤寒沙门氏菌、肠炎沙门氏菌、猪链球菌、产气荚膜梭菌和胞内Lawsonia野外分离株生长所需的最低抑制浓度。这种细菌可以感染家禽、猪和牛，因此有关GoldEdge+抗菌活性的信息可能会影响加拿大的几个畜牧业。
