La presencia de campylobacter en pollos de carne alimentados con diferentes niveles de butirato sódico en dietas experimentales

Comparisons of the effect for five different levels of butyrate were carried out, with or without the associated minero-vitamins mixture supplemented with essential amino acids and additives in the starter feed for phase I, 1-15 days old, resulting in ten treatments in total. In the diets for phase II, 16-36 days old, there was no feed mixture and just one level of SB in the treatments for samples 2 to 5 and 7 to 10. The samples 1 and 6 were the control group without SB. For this work we used a total of 960 one-day old broilers (Cobb-500), obtained from a commercial hatchery. The broilers were distributed into ten experimental treatments, with 8 repetitions per cage per treatment and 12 birds per cage, with a total of 80 cages and 960 broilers. At the end of the experiment after 36 days, a swab was collected from six birds per cage to assess the presence of campylobacter, but not positive results for this microorganism.
