Dear All! I like Dr. Ruiz's arguments very much. Restricting feeding, besides light control, is a very complicated issue once we depend on people to make the restriction, and it is impossible to see all farmers doing whatever should be done, based on the company´s recommendation. At the hottest period of the day, leave the chicken alone. This is a recommendation to broilers that are produced ...

Whilst I was managing a poultry research facility, our standard operating procedure was to formulate diets based on actual ingredient amino acid values and not meet a crude protein minimum. This is typically not practical for day-to-day formulation. However, it should be possible to do periodic amino acid analysis of ingredients to determine the total amino acid protein and non protein nitrogen co ...

All commercial poultry eat with reasonably good precision to balance nutrient intake with requirements. Short term, there can be some variation in feed intake related to local situations, but long-term, the mechanisms of feed intake regulation are quite precise. Matching nutrient needs with intake is an obvious inherent evolutionary necessity to ensure survival and reproduction. A bird’s dai ...

Interesting results. Compared to a 1050 micron particle size mash diet, what are the costs to produce a? - High quality pelleted diet: 90% pellet; 10% mash- Industry standard quality pelleted diet: 60% pellet; 40% mash?

Dr. Ruiz, thank your for your salient and well documented comments. We know that fermented soybeans in the form of tofu are a staple in the diets of people around the world. Do you know of any work which has been done evaluating it’s feeding value in animal diets. In addition to the process potentially impacting TI, it is likely that there would be an effect on the carbohydrates in ...

Thank you. I want to be clear on the antibiotic combination to use for fowl cholera/typhoid

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 ...

Phytogenic compounds, probiotics and organic acids are used in broiler feeds as an option to AGPs due to their ability to emulate properties of antibiotics. This study’s goal was to compare a field AGP (virginiamycin 100 g/MT) program (T1) with two antibiotic free programs: Lactococcusbased probiotic+yeast MOS+a blend of Italian Chestnut-C/Argentine Quebracho-Q bioactive ex ...
