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.

在过去的几年中，抗生素在农业中的使用发生了许多变化。最值得注意的是，现在只有处方才能获得所有用于兽医使用的医学重要抗生素。这些和其他变化导致动物饲料中的抗生素减少或消除。饲料中的抗生素已经使用了数十年，它们的使用表现出非常积极的治疗作用，例如改善的饲料转化率，发病率降低以及加拿大牲畜的临床和亚临床疾病较少。随着对抗生素使用的新限制，加拿大牲畜行业正在积极寻求抗生素的替代方法，以添加饲料以充当“增长/健康促进者”。 Proveta Nutrition，Ltd。拥有一种名为GoldEdge+的产品，可改善层鸡产生的鸡蛋数量，这表明它可能会对它们的生产力和健康产生积极影响。我们将执行微生物学分析，以确定杀死或抑制大肠杆菌，鼠伤寒沙门氏菌，肠菌，苏伊斯链球菌，suis链球菌，perfridium perfridium perfringens和lawsoniaiaiaiaiaia insacellarialis的田间分离株所需的最小抑制浓度。细菌可以感染家禽，猪和牛，因此有关戈德奇+抗菌活性的信息可能会影响加拿大的几个牲畜行业。
