Implications The host DNA in faeces presumably originates from gut cell losses. This development of a non-invasive assessment method is potentially a novel indirect measurement of gut cell losses, although further validation experiments are required. A yeast-inclusion diet significantly reduced pig DNA in faeces and therefore may reduce gut cell losses. Turnover of gut cells contributes to feed e ...

In response to Dr. Marchenkov. Sorry, but I disagree very strongly! Animal feed mixing is very predominantly a dry mixing process. As soon as you add small quantities of ANY liquid into this dry mix you start to get "balling" where dry particles aglomerate. This immediately reduces homogeneity. As well as the basic physical mixing problems of adding liquids to a solid mix, we have the additional p ...

Dear Dr. Milena Sevastiyanova, Thank you for the article. I feel that the conclusion that the product Luminance can replace Colistin has not been shown effectively in this trial. As the PWD symptoms were not seen the use of colistin was unnecessary and so it cannot be concluded that the product provided an effective replacement. Also there are no stats or negative control in this study so it is ...

Good story, with consistent fundamentals. However, I have some doubts about what I would like to clarify. - There is no doubt about the bactericidal action of short chain (acc) and medium chain (acm) acros. My question as a researcher is that normally the immune challenge of the animals in the experiment is appreciably less than the field level, in which case the acc and acm may prove as efficient ...

Dear Prof. Donzele, I agree piglet numbers are constrained in this work and as it is a challenge study we expect to see a larger degree of variation so would drive a need for more piglet numbers. There were numerical differences in feed intake but this was highly variable due to age of piglet and health implications following the K88+ challenge, therefore it was not significant. In larger scale wo ...

Hi Pablo, Thank you for your comment. Yes this the first piece of work we carried out looking at the effect our products had following E.coli challenge. We have subsequently done work with veterinary groups on farms replacing zinc oxide in their weaners.

Background and objectivesThe recent EU ban on therapeutic levels of zinc in animal diets has led to concern regarding potential performance losses and animal welfare. Potential alternatives such as organic acids have been shown to be beneficial in reducing gram negative bacterial and promote digestibility (Canibe et al., 2001; Mroz, 2005). These properties may also help in the replacement of zinc ...
