Avaliou-se na Universidade Estadual Paulista (UNESP) em jaboticabal, a presenca de microorganismos nas silagens de graos umidos de milho. Os tratamentos constaram de cinco percentagens de sabugo na silagem (0,5,10,15 e 20% na materia verde) e quatro periodos de amostragem apos a abertura dos silos (0,2,4 e 6 dias), em esquema fatorial, num delineamento inteiramente casualizado, com tres repiticoes. O crescimento de laactobacilos foi maior na silagem exclusiva de graos. A presenca de clsstrideos diferiu entre os tratamentos, com valores entre 1,30 e 3,32 oog UFC/g de silagem. A presenca de leveduras enterobacterias aumentoueem funcao das proporcoes de sabugo e dos periodos de amostragem. A populacao de lactobacilos foi satisfatoria para uma boa fermentacao das silagens, e a presenca do sabugo favoreceu o desenvolvimento do clostrideos e enterobacterias apos a abertura dos silos. |

Antibiotics such as chlortetracycline (CTC) have been used to promote growth of pigs for decades, but concerns over increased antibiotic-resistant infections in humans have prompted the development of alternative strategies. Developing alternatives to antibiotic growth promoters (AGPs) could be informed by information on the mechanisms of growth promotion, notably, how AGPs affect the microbial populations of the gastrointestinal tract. Pigs from three sows were aseptically delivered by cesarean section. Six piglets were distributed to each of two foster mothers until weaning, when piglets were fed a diet with or without 50 mg/kg CTC for 2 weeks. The ileal bacterial microbiota was characterized by using a cultivation-independent approach based on DNA extraction, PCR amplification, cloning, and sequencing of the 16S rRNA gene pool. The ileal and mucosal communities of these growing pigs were dominated by Lactobacillus bacteria, various members of the family Clostridiaceae, and members of the poorly known genus Turicibacter. Overall, CTC treatment resulted in three shifts: a decrease in Lactobacillus johnsonii, an increase in L. amylovorus, and a decrease in Turicibacter phylotypes. The composition of the microbiota varied considerably between individual pigs, as revealed by shared operational taxonomic units (OTUs) and similarity (SONS) analysis (theta(YC) values). While the observed variation between untreated pigs obscured the possible effect of CTC, integral-LIBSHUFF and SONS analyses of pooled libraries indicated a significant shift due to CTC in both the lumen and the mucosa, with some OTUs unique to either treated or control ileum. DOTUR analysis revealed little overlap between control and treated communities at the 3% difference level, indicating unique ileal communities in the presence of CTC.
