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, …

The objective of this study was to evaluate effects of intermittent suckling on sow and litter performance. Seventeen crossbred sows and litters were randomly assigned to treatment groups seven days prior to weaning: continuous suckling (CS) and intermittent suckling (IS; litters removed for 6 hr each from day 21 to 28). Litters were weaned at 28 days of age. Feed and water were available to litters and sows at all times. Feed intake was recorded. Body condition scores were collected on sows before farrowing and at weaning. Number of days to return-to-estrus for the sows was also recorded. Litters were …
