Title: The effects of group size and subtherapeutic antibiotic alternatives on growth performance and morbidity of nursery pigs: a model for feed additive evaluation Document date: 2018_7_6
ID: r6xzqu6a_19
Snippet: Pigs were weighed by pen on a floor scale (validated with a standard check weight at each use) at the beginning and end of the experiment, and at the end of each feed phase (days 11 and 24) to determine ADG. Feed offered was weighed by the automatic feed delivery system, and remaining feed was weighed at the end of each phase to determine ADFI and G:F, measured as total BW gain:total feed intake. Pen, removal date, BW at removal, and reason for r.....
Document: Pigs were weighed by pen on a floor scale (validated with a standard check weight at each use) at the beginning and end of the experiment, and at the end of each feed phase (days 11 and 24) to determine ADG. Feed offered was weighed by the automatic feed delivery system, and remaining feed was weighed at the end of each phase to determine ADFI and G:F, measured as total BW gain:total feed intake. Pen, removal date, BW at removal, and reason for removal were recorded for each pig found dead or removed from the study. This information was used to calculate pig days for each phase and the overall experimental period.
