Formatted Abstract/Summary
Free range accounts for approximately 15% of Australia‚Äüs commercial egg production. Although this system allows hens to express full behavioural repertories, hens held under free-range conditions are exposed to various microbial agents that can influence the bacteria present in their intestinal and reproductive systems, resulting in a wide range of disease problems. Pathologies such as oophoritis, salpingitis, peritonitis, salpingo-peritonitis and metritis are frequently encountered at onset and during the laying period, subsequently causing health problems and reduced egg production. One key problem facing free-range egg industry is that there are virtually no suitable medications for use against infections of the reproductive tract. Therefore poultry scientists and producers are looking to developing healthy alternatives to antibiotics, and probiotics have often been proposed as a natural choice. The objective of this study was to explore the ability of commercial probiotics for laying hens applied in drinking water for 4 weeks before the start of lay in reducing the occurrence of reproductive tract pathologies in laying hens, and improving hen general health and performance. The results demonstrated that the use of probiotics in the drinking water (n=6 flocks, n = 3 control flocks) significantly reduced (P<0.01) the occurrence of reproductive tract pathologies (22% vs. 44% of birds necropsied) and decreased (P<0.01) mortality of hens (1.3% with probiotics compared to 3.8% without). Egg production was also increased (P<0.01) at peak of lay (90% vs. 75%). The results of this study provided some initial evidence that the manipulation of bacterial communities by administration of a probiotic could be a useful approach to control and prevent reproductive tract infections in hens kept in free-range.
