The developer said the form of the product enables it to deliver intrinsic resistance in pelleting feed to combined temperature, friction, and moisture without the need for foreign material coating.
Poultry trials in various global locations have shown the product delivers in terms of feed efficiency and production performance in birds, said the company.
“A wide range of benefits, confirmed by peer-reviewed poultry trials, include improved gut microbiota diversity, gut function and digestibility; improved feed use efficiency, reduced FCR, higher body weights, and enhanced survival rates.”
Trial data
A 2021 peer-reviewed study, conducted by He et al, showed the probiotic had positive effects on gut morphology in poultry with a significant increase in villus height observed at day 24. Actisaf Sc 47 HR+ was also shown to help birds achieve significantly improved villi height vs crypt depth ratio, compared to birds in both a control group and an antibiotic treatment group, said the firm.
A US study, run by Texas A&M university (TAMU), and carried out last year also evaluated the probiotic product. Birds were vaccinated at one day old with live coccidiosis vaccine, at a double dose, they were fed a corn-soy diet with 5% DDGs throughout the study and were raised on used litter. The birds in two Actisaf Sc 47 HR+ groups (representing different feeding rates) achieved significantly better FCR, compared to birds in both a control group and an antibiotic group, reported Phileo Lesaffre.
The company also reported results from a field trial carried out on a broiler farm in Eastern Europe in 2022. “Broilers were floor-raised for 39 days in two houses. In the first house, the birds were fed a basal feed without yeast probiotic supplementation. In the second house, birds were fed a basal feed supplemented with 400 g/T of Actisaf Sc 47 HR+. At day 39, broilers in the Actisaf Sc 47 HR+ group achieved better production performance across all parameters (body weight, survival rates, feed efficiency, etc.). The trial also yielded in an 8:1 return on investment (ROI) for the broiler farm.”
