Dear, Sandro Cerrate,I fully agree with your statement that the ideal would be to work with different rations respecting the age and body weight of the rooster, this also serves for the female because the maintenance requirement will vary according to body weight and physical activities and in the case of female still producing eggs. However, in practice, this is almost impossible due to problems ...

Dear Sandro Cerrate,My name is Carlos Borges I am a Nutritionist and I work with consultancy ( C Borges Consultoria)here in Brazil.My PhD thesis was on “Nutritional Requirements of Protein and Energy for Breeding Roosters in the Production Phase”During the work that was quite long, because we worked with the roosters still in the breeding and before mating and we took the experiment un ...

Dear Dr Fawad Khalil Organic acids that are used in animal nutrition are most effective at low pH. For this reason, its action is more efficient in the region close to the proventricle and decreases considerably in the duodenum where the pH is above 5. This is because the organic acids used in nutrition have pKa below 5, consequently the mixtures of these acids will be buffered in the intestinal ...

Dear FredericAt first, yes, all acids or products that lower the pH of the water could be used. However, we must remember that HCl and H3PO4 are inorganic and strong and can damage your piping and compromise the water supply for birds.In Brazil, some producers use acetic acid (vinegar) to clean the water box and piping, but do not use it often to prevent equipment corrosion.Phosphoric acid (H3PO4) ...

Dear FredericI will try to answer your questions.Firstly, the objective of using organic acids in water is to lower the pH of the water itself, as most pathogenic bacteria do not grow in environments with pH <4.0.Ammonia is used in these products precisely to buffer the pH of the water around 4.0, because if the pH drops too much, the birds can decrease the consumption of water and feed.Organic ...

All short chain organic acids used in animal nutrition have pKa between 3.8 to 5.0 and, if not protected with vegetable fat, do not pass the duodenum at significant concentrations as they will be absorbed and used as energy sources by different routes metabolic.Some organic acids such as formic, sorbic and benzoic have a higher efficiency than others in controlling gram-negative bacteria such as S ...
