1 Transition to Antibiotic Free: Tips and Tricks January 2018 Greg Wideman, DVM

2 Key to successful antibiotic free production: RWA, ABF, NAE etc

3 Some of the small stuff Data and information management Disease elimination and control Weaning age Colostrum Farrowing room hygiene Piglet handling Iron/anemia Barn setup and management Water quality and treatment Communication

4 Data management Continuous measurement and review of key biologic and economic performance indicators Simple No duplicate data entry Web-based Close-out oriented Inventory tracking for program and treated pigs Benchmarking

13 Disease Control and Elimination OPIC AMU Project (2014) Goals: Quantify the amount and class of antimicrobials used to raise pigs from breeding to slaughter on a subset of Ontario farms. Understand the key drivers impacting on-farm antimicrobial choice and usage. Assess an AMU benchmarking strategy consider pros and cons for future efforts This project was funded in part through Growing Forward 2 (GF2), a federal-provincial-territorial initiative. The Agricultural Adaptation Council assists in the delivery of GF2 in Ontario.

14 OPIC AMU Project (2014) Demographics 36 volunteer farms (mean 440 sows) 105 sites 34,647 sows 867,329 piglets 839,913 weanlings 688,831 market hogs 13 volunteer feed suppliers 4 volunteer veterinary practices

15 Targets for Disease Elimination

16 Economic analysis of health costs associated with PRRS+ vs PRRS- production systems from Holtkamp, 2013

17 Mycoplasma hyopneumonia (MHP) drives antibiotic use

18 Success rate of MHP elimination projects from Yeske 2016, AASV

19 Disease Elimination - MHP year dressed weight ADG FCR Mortality % Mh+ average Mh average pigs per year Mh- allowed removal of two 1-wk pulses of in-feed ctc 22mg/kg BW, overall G/F antibiotic use reduction 75%

20 Disease Prevention/Biosecurity Safe and secure gilt supply Incoming gilt isolation Transport plan especially cull sows and pigs Minimum Danish entrance standard Culture of audit, review and discussion

21 Farrowing Room Fine-tuning Colostrum measurement and management (immunocrits, split suckling, inducing)

22 Lets Colostrum Produced prior to farrowing kg colostrum per sow Only expressed during first 24 hours after farrowing 80% reduction of antibodies by 24 hrs Pre weaning mortality Scours, swollen joints, greasy pig Lifetime performance Health and disease resistance Growth Age at puberty of gilts! Gilts future # born alive, litter growth rate!

23 Can we improve colostrum quality? Warm dry piglets! Parity structure Vaccines Nutritional supplements Careful induction of farrowing Can be measured! Brix refractometer Ig immunocrit ELISA/RID Meloxicam pre farrow Colostrum replacement (bovine)

24 Farrowing Room Fine-tuning Colostrum measurement and management (immunocrits, split suckling, inducing) Piglet chilling measurement and management (FLIR, drying, 24hr farrowing care)

25 Chilling

26 Farrowing Room Fine-tuning Colostrum measurement and management (immunocrits, split suckling, inducing) Piglet chilling measurement and management (FLIR, drying, 24hr farrowing care) Iron status measurement and management (HemoCue Hb 201+, iron reconciliation)

27 Data Management again!

28 Anemia Monitoring Hemoglobin assay, on farm test Verification of iron program

29 Weaning Age Impact of young pigs Impact of variation Implications on colonization/infection with bacterial pathogens

33 Pull count Combined pull count by week Average pull count: pigs/week Week Pull counts from Largie and Ptbo presented together

34 Sow Herd Weaning Age/Weight Interventions Correct split-suckling Eliminate late fosters Off-label use of Regumate to prevent early farrowings Coccidioisis control Review farrowing crate down days Review farrowing room treatment SOPs and efficacy Shipping room feed/water/temperature Replace water pump, focus on lactation feed intake

37 Why treat a Livestock Water System? 1. Make un potable water into potable water 1. Microbiological 2. Mineral 2. Treat/remove biofilm 3. Direct effect on pig 1. ph of gut 2. Direct nutrient value of water additive 3. other?

38 Water Quality Water availability Water palatability Pig pathogens in water (e.g. coliforms) Biofilm in water lines
