Farrowing Strategy Change-Belstra Farms
• Needed to increase piglet weaning age • Minimize age spread between nursery and
finisher groups • Capture the value of 2-2 ½ lb piglets due to
high born alive • Provide a better opportunity for immune
stabilization in nursery/finish population • Increase feed intake in lactation • Minimized cross-fostering after 24 hours post
birth • Eliminated bump weaning • Implemented a modified MCREBEL

McREBEL Management Changes to Reduce Exposure to
Bacteria and Eliminate Losses
• Information for this power point was gleaned from: 1. The article “Management Changes to Reduce Exposure to Bacteria and Eliminate Losses” by M. McCaw 2. A case report: “Effect of reducing crossfostering at birth on piglet mortality and performance during an acute outbreak of porcine reproductive and respiratory syndrome” by Monte B. McCaw, DMV, PhD. 3.McREBEL Management System (Strictly limited cross-fostering) for Controlling PRRS Associated Disease Losses in Suckling and Nursery Pigs by M.B. McCaw, A. Holtcamp, J. Roberts, P. Davies

McREBEL Management Changes to Reduce Exposure
to Bacteria and Eliminate Losses
Underlying Philosophy: to optimize growth of suckling pigs one must minimize interventions and maximize supportive care
3/04/2009 Page 5
McREBEL Procedures
• McREBEL objective: to maximize the number of piglets remaing on their birth mother and to maximize the number of piglets remaining on the colostrum mother
• Do not cross-foster after 24 hours of age -move the min. number just to fill functional teats -do not cross-foster to create uniform size or single gender -smallest pigs have lowest priority and are left by mom as “extras” if more pigs than functional teats

Belstra Deck Strategy • 1 deck/12 farrowing stalls • 8 cups/room of 24 stalls • Cup and deck placement is on the fan end of the room for
warmth • Pre-Heat deck before placement of pigs • Split nurse and foster all litters at day 1-foster all sows with
average born alive for that day • Day 3-4 place compromised pigs in the deck • Day 12-14 place compromised pigs in the deck • Start creep feeding at 7-10 days with a snap down pan

Sow performance parameters Iroquois Valley Swine Breeders
current production • 1,100 sows

Cost of Rescue Deck Technology • $1.00 per weaned pig
– .75¢-.90¢/pig in milk replacer – .10¢/pig in equipment cost depreciated
over 4 years
Summary $29,560.00/year
Value Propositions for Farrowing Strategy Change
3/04/2009 Page 13
Decreased Wean To Estrus Interval
• .8 Day WEI reduction due to Strategy Change • .8 x 2.41 l/s/y = 1.93 per sow increase in productive sow
days • 1.93 days x 1100 sows = 2123 productive days gained
($1.00/day non-productive cost)
320 productive days/sow • 2123 ÷ 320 = 6.63 sows that are more productive • 6.63 sows x 26.9 PSY = 178 piglets
Summary 178 x $32.00 = $5,696.00
Value Propositions for Farrowing Strategy Change
3/04/2009 Page 14
Average weaning weight increase • Increase of 2.6lb with new strategy • Think in terms of weaned pig contract
– 13lb/pig = $32.00 base – .50¢ / lb for every pound over 13lbs
– increased value of $1.10 / weaned pig
Summary 28,000 (95% sold) x $1.10 =
$30,800.00
Value Propositions for Farrowing Strategy Change
3/04/2009 Page 15
Reduced pre-wean mortality • Reduction of 2.3% • .29 pigs / litter increase
– 12.5 BA x 2.3% = .29 p/l • 2651 litters/year x .29 = 769 additional
pigs
Summary 769 x $32.00 = $24,608.00

3/04/2009 Page 16
Nursery Mortality • Reduced from 5% to 1.5% • Net reduction 3.5%
• 29,590 pigs weaned x 3.5% = 1,036 pigs saved
