Some impressive FCR improvements from Typlex®.
480 male Ross 308 birds used in 6 treatments, control and ferric tyrosine added at 0.01, 0.02, 0.05, 0.10 and 0.20 g/kg. At day 20 litter from a known campylobacter positive commercial flock was added to all pens.
At day 18, 1 bird/pen was sampled cloacally for campylobacter enumeration and at 42 days pooled caeca from all pens were assayed for campylobacter.
At 0.05g/kg the additive significantly (p<0.05) reduced campylobacter cfu/g from log10 5.124 to 4.377
Some fairly impressive FCR improvements also noted (p<0.05), control FCR was 1.637 and all additive treatments below 1.550
