I. INTRODUCTIONPoultry feed is routinely pelleted for many reasons such as increased feed intake, feed efficiency, and feed hygiene (Abdollahi et al., 2013). However, pelleting is not without its drawbacks, particularly when using higher pelleting temperatures (Abdollahi et al., 2010). The industry has been trending towards ever higher conditioning temperatures due, at least in part, to efforts to ...

@M.C. Fernando R. Feuchter A. - Acetic acid (active ingredient in vinegar) can also be metabolized by some microbiota, but to a lesser extent (in my experience) than citric acid. One issue that can come up is the rather low acetic acid concentration in vinegar (generally 4 to 6%). Even if you are going to be further diluting the vinegar in drinking water, there is still the cost associated with tr ...

Gene Pesti, as evidenced by several research works (Zhand & Adeola, 2017; 2018; Fang et al., 2007 – poultry and pigs) and pointed by Aaron Cowieson, SID Ca/P is more additive in complex mixtures. Some nutrient recommendations have already started using SID P (NRC, 2012) in feed formulations as pointed by Joshua Jendza. Therefore, a concurrent use of SID Ca is necessary because of the int ...

Aaron Cowieson - The benefits of using standardized digestibility is exactly as you say, but I was of the impression that using Ileal instead of total tract digestibility was more a matter of convenience. We already collect illegal samples for SID of amino acids, and using those same samples for mineral analysis as well is simply easier than collecting a separate excreta sample. Particularly when ...

Thank you for your pushback against overly optimistic marketing language.
Synergy is a word often used, but an effect rarely demonstrated in organic acid trials. Additivity is far more common. This is becuase for most organic acids, the mode of action is the same, and the pH of the environment in which the acids are expected to operate are either too high or too low to allow for the ...

Dear Dr. Rajendra,Thanks for your adequate feedback and clarifications.I can't more than agree with some of your statements such as the feed preservation efficacy of propionic and formic acid: in fact "decontaminants" rather than "organic acids". And for sure, since decennia most industrial preservatives have been based on propionic and formic acid and their salts and are abundantly used. But thes ...

Thanks for this information, interesting, but revealing a lot of questions or request for more detailed information.1) Could you document the synergism between the organic acids and salts you are using in your product? Meaning each time the individual effect at the used level and then the various combinations?2) What is the dosage you recommend and what is the level and concentration you are reach ...

Fermentative effects are driven more by the diet than the acid.
Unprotected acids are absorbed or metabolized vaguely early in the foregut. Effects on the hind gut are indirect, in that they acid affects the foregut, and those effects have a carryover effects on the hind gut - where fermentation occurs. By the cecum or colon, all of the acid added to feed or water ...
