“…Similar results were found by Li et al (2005) when a Bacillus subtilis culture was used. It has been proposed that these effects are achieved by different mechanisms, including competitive exclusion of pathogens (Morishita et al 1997;Nisbet 1998) and improved digestion and absorption of nutrients (Thomke and Elwinger 1998). There have been some previous attempts to correlate gut microbiota with higher levels of performance (Apajalahti et al 2004;Torok et al 2008).…”

Abstract.A study was undertaken to investigate the ability of two commercial probiotics applied in free-range laying hens (from 18 to 22 weeks of age) in reducing the occurrence of reproductive tract pathologies, and improving hen health and performance. In all, 630 17-week-old brown layers were transferred to a freshly cleaned free-range laying facility, and randomly divided into three groups, with three replicates of 70 birds each. Both probiotics were administered in the drinking water (Groups 1 and 2) on a daily basis for 4 weeks, while Group 3 was left untreated. At 38 weeks of age, the results demonstrated that treatment with either probiotic significantly reduced the occurrence of reproductive tract pathologies (control vs probiotics, 33% vs 22% and 11%; P < 0.01), mortalities (control vs probiotics; 3.8% vs 1.5 and 1.9%; P < 0.01), and increased the performance of hens, for another 20 weeks post-treatments (hen day production for control vs probiotics 75% vs 90% and 94%; P < 0.01). Birds treated with probiotics maintained their bodyweight and egg weights at standard ranges, while untreated birds did not perform at this level. Although we were unable to show any effect on cloacal bacterial colonisation, the results of the present study provided some initial evidence that reproductive pathologies that often cause drops in egg production and sudden deaths of birds, can be reduced if free range hens are treated with a commercial probiotic before or during the onset of lay. The use of a probiotic benefits the health and performance status of hens, resulting in better hen welfare and significant economic gains to egg producers.

“…In the monogastric camp, alternatives to antibiotics were, as expected, mostly studied in pigs and poultry (Thomke and Elwinger, 1998;Doyle, 2001). Because of the peculiar digestive physiology of the rabbit, it can be hazardous to simply extend the conclusions of such studies to this species.…”

“…Among such substances are organic acids, hydrogen peroxide and bacteriocins, which can kill other microbes, alter their metabolism, and/or reduce their production of toxins (Rolfe, 2000). But it should not be forgotten that some of these mechanisms were verified in vitro, and so need to be substantiated in vivo to be more than hypothesis (Thomke and Elwinger, 1998;Guillot, 2001).…”

“…In some studies, animals were used as a human model (Thomke and Elwinger, 1998 A significant number of trials show positive effects of probiotics, especially among younger animals, such as chicks and piglets, raised in less than ideal hygienic conditions (reviewed by Thomke andElwinger, 1998, andSimon et al, 2003). But a certain number without positive or even negative effects have also been published (Doyle 2001).…”

This review is focused on the most studied and developed substances which are commonly known as alternatives to dietary antibiotics, particularly as far as rabbit feeds are concerned. After a reminder of the reason to be and success of antibiotic growth promoters, and why they lately came to be banned in the European Union, we successively deal with probiotics, prebiotics, enzymes and organic acids. Data on rabbits are, as expected, quite scarce when compared to species such as pigs and poultry. Nevertheless, the available performance results are discussed together with the possible mechanisms of action. Special mention is made of the effects of these substances on digestibility and caecal activity.
