Effect of dietary probiotics and prebiotics on the performance of broiler chickens.
Poultry Science, 2019 The prolonged use of antibiotics has led to the development of resistant bacteria and also led to accumulation of antibiotic residue in the poultry feed, this ultimately led to the prohibition of antibiotics as growth enhancers in animal production. Thus,

Relevance of Water Quality to Broiler and Turkey Performance
Poultry Science, 1996 Water was tested from 300 broiler farms in Arkansas in cooperation with three integrated poultry companies, each having at least two locations in the state. The turkey study was conducted in cooperation with three integrated turkey companies with samples from 100 turkey farms, although the numbers were not equal among companies.

Evaluation of Ammonia Stress and Coccidiosis on Broiler Performance
Poultry Science, 1979 Eighty broiler chickens were randomly assigned to each of 12 chambers in a controlled environment poultry facility. Ammonia gas was injected at 0, 50, or 100 ppm from 28 to 53 days of age. All chicks, except the control pens, were innoculated with coccidia at 36 days of age.

Antimicrobial Use in Livestock: The Economic Cost of Action or Inaction
Journal of Agricultural Economics, EarlyView.ABSTRACT This paper quantifies the economy‐wide consequences of two independent global stress‐tests in livestock production. The first assesses the effects of phasing out antimicrobial growth promoters (AGPs), and the second evaluates the long‐term impacts of antimicrobial resistance (AMR) progression.
