Effects of a direct-fed microbial (primalac) on turkey poult performance and susceptibility to oral Salmonella challenge.
A study was conducted to determine 1) the effect of a dietary direct-fed microbial (DFM) on turkey poult performance, 2) the effect of a DFM on a Salmonella challenge, and 3) the effect of feed processing on the efficacy of the dietary DFM. Day-of-hatch Large White female poults were placed in 2 rooms in 2 Petersime batteries per room. Twelve pens of 7 birds each were used in each battery (24 p...

Evaluation of selected direct-fed microbial candidates on live performance and Salmonella reduction in commercial turkey brooding houses.
As effective probiotic Bacillus isolates that can increase BW gain (BWG) are identified, they may offer advantages in terms of stability, cost, and feed application over probiotics limited to drinking water application. Additionally, an effective direct-fed microbial (DFM) may offer an effective alternative to antibiotic growth promoters. Previously, 4 Bacillus isolates were identified and eval...
