The use of Challenge conditions and coccidiosis challenges in an experiment makes the interpretation of research as it applies to commercial conditions more difficult. I have found that reducing density and feeding a consistently good quality diet will enable a production manager to determine which products work in his operations and the products that give a positive return.

Robert Swick . Excellent comment on sustainability, however do not discount the sustainability of the chemicals used to produce the amino acids and vitamins. Many times the production of these nutrients using chemicals is an integrated operation and they used chemicals (by products) from the production of other products. Many times cyanide and HCl acid are in surplus from other reactions. To get a ...

Andy G Tuazon; Dr. Tuazon, I have not used the Gastec ammonia detector. We have used the following hand held detectors, Drager, PAC 7000, 3-M's Single Gas Detector model 450-455-104 A, and the Honeywell gas detector model 128-266-1-3. These gas detectors are available from the Grainger distribution company 9avaiable on line). All of these models can detect the ammonia, however they assay only for ...

Adam Fahrenholz Dr. Fahrenholz, May I disagree with you on less uniformity ifor feeds for older animals that have a larger meal intake as compared to a chick with a smaller meal intake. I believe that we are not only meeting the animal’s needs, but also we are feeding and altering the entire biome in the animal. A larger animal has the body mass to tolerate variations in meal intake as compared to ...

We face a global challenge in feeding a rapidly increasing population, while using fewer resources to do it. In short, we need to do more with less. This sustainable global food challenge will take a variety of players and approaches to resolve, but technology will undoubtedly be central if we are to be successful.Digitization, the Internet of Things and more powerful software all offer new tremen ...

Ammonia levels are problem in modern poultry houses with South or North American or European production methods. Ammonia can be controlled with very low stocking densities and/ or high ventilation rates and deep litter, however it will difficult to make a profit. Thus Dr. Czarick’s work on continuous detection of ammonia is very important. Our goals are for 10 ppm of ammonia. This level is a ...

Interesting comment about the CV's of mixer tests and the 1985 date for the 10 % CV acceptability. While employed at Degussa, now Evonik in the 1980's mixer profliles were offered as a customer service. At that time a standard was needed to compare for % CV's for mixer profiles. The standard at that time, around 1985, was the Kansas State research on mixer profiles using the QuanTab salt assay. T ...

A couple of quick remarks on this topic. When phytic acid is hydrolysed by phytase and the mucosal phosphatases in the intestine the only two direct products of this are myo-inositol and phosphate. We have measured the appearance of both of these in multiple experiments and this is clear evidence of phytase efficacy and its compatibility with endogenous phosphatases in the intestine. All additiona ...

Good summary article, but take care, grain and soya products also have a host of problems like the meat products cited. I have fed broilers no meat product diets for 20 years and there are problems with these grain, soybean meal, canola meal, pea protein, isolated protein sources, millet and sorghum based diets.
Excellent nutrition is required for successful animal production with either type of ...
