A study was conducted to examine broiler performance and carcass yield across 5 consecutive commercial broiler flocks after the removal of roxarsone (ROX) and growth-promoting antibiotics (GPA) from the feed. Over a 1-yr period, approximately 552,000 broilers were reared in 4 solid-walled, tunnel-ventilated houses, divided into 2 paired-house facilities, and were assigned 1 of 2 dietary treatments. The treated group received basal diets containing salinomycin, ROX, and GPA, whereas the control group received the same diets without ROX and GPA. Average BW were recorded for 200 sample birds/treatment per flock at 18, 35, and 48 d of age. Average BW, …

Poultry litter is one of many components resulting from the production of broilers. Understanding poultry litter microbiological composition is very beneficial when attempting to improve the broiler's environmental conditions and searching for the best uses for this valuable industry by-product. The objective of this study was to collect samples of poultry litter throughout the United States and determine the presence of bacteria in the litter. Tests were conducted for total bacteria, Gram negative bacteria, Gram positive bacteria, Staphylococcus, Escherichia coli, and coliforms. Poultry litter samples were taken from 12 different regions throughout the United States and were analyzed …
