Supplementary data for: Randomized controlled trial assessing the effects of xylazine sedation in 2 to 6-week-old dairy calves disbudded with a cautery iron
Borealis
Reedman, Cassandra N.; Duffield, Todd F.; DeVries, Trevor J.; Lissemore, Kerry D.; Duncan, Ian J.; Winder, Charlotte B. — 2021-02-18 Data from various models as a part of a randomized controlled trial evaluating the effects of xylazine sedation for cautery disbudding in dairy calves. This data is from mixed linear (total daily milk consumption, haptoglobin concentrations, latency to drink milk following disbudding, average lying bout length and length time to perform the disbudding procedure), Poisson (entitled visits to the automated feeder and number of lying bouts) and negative binomial (unentitled visits to the automated feeder) models by time relative to disbudding, stratified by treatment group.

Supplementary material: Effect of a milk by-product based calf starter feed on dairy calf nutrient consumption, rumen development, and performance when fed different milk levels
Borealis
Parsons, Sarah D.; Steele, Michael A.; Leslie, Ken E.; Renaud, David L.; Reedman, Cassandra N.; Winder, Charlotte B.; DeVries, Trevor J. — 2021-10-18 The objective of this study was to determine the effect of a milk by-product based feed treatment compared to a conventional grain-based ration on feed intakes, rumen development, and growth of heifer calves fed two different levels of milk. This data is from mixed linear models, with the data presented for treatments separated by factor (milk treatment and feed treatment) rather than the treatment interactions.

Ancillary analysis for: Relative efficacy of antimicrobial treatments in dairy cattle to cure existing intramammary infections: a systematic review and network meta-analysis (1990-2019)
Borealis
McMullen, Carrie K.; Sargeant, Jan M.; Kelton, David F.; O'Connor, Annette M.; Reedman, Cassandra N.; Hu, Dapeng; Glanville, Julie; Wood, Hannah; Winder, Charlotte B. — 2021-09-27 This data is an ancillary analysis conducted for the systematic review and network meta-analysis to investigate the relative efficacy of antimicrobials to cure existing intramammary infections in dry cows. This ancillary data was used to analyze the results of trials published between 1990 - 2019 because eradication programs for Streptococcus agalactiae, a bacterium very susceptible to penicillin products, were implemented in the 1980s and achieved low levels of this pathogen in dairy herds (Makovec and Ruegg, 2003; Keefe, 2012), such that penicillin products could have an inflated measure of cure of existing IMI within the network in studies prior to 1990. This analysis was not pre-specified in the protocol, nor did it provide inferences that differed from the full network meta-analysis.
