Kevin Downs (Middle Tennessee State University) and Joseph Gulizia (Auburn University) talk with Sam Shafer (PSA) about the results of providing poultry with different colored feed and how that impacts the birds' feeding preferences. They also discuss what this study means for further research on this topic. This is a follow-up from a previous episode regarding the findings of this study.

INTRODUCTIONThe use of soybean meal in poultry diets can be tested for antinutritional factors, which is easily identified with ureatic activity and protein solubility in KOH analysis. This research aimed to evaluate soybean meal quality measured by ureatic activity and KOH solubility in poultry feed mills.MATERIAL AND METHODSFor this analysis, 283 samples were obtained from a broiler feed mill lo ...

IntroductionSoyabean meal is the most important source of dietary protein for poultry in South Africa and much of the world. The increased use of vegetable protein meals in animal feeds has been brought about through consumer pressure for more sustainable and welfare oriented animal protein production.  The increased use of vegetable protein sources has highlighted the importance of protein q ...

John Htoo, Based on the summary presented, I would like to highlight as correct, the decision of the team of researchers responsible for the work, to have used a suboptimal level of lysine to determine the best tryptophan relationship with lysine. This decision-making is justified by the fact that animals require grams of amino acids per day or phase, not percentage. Thus it can be deduced that th ...

Distillers dried grains with solubles (DDGS) has a high concentration of Leu, and the Trp requirement for growing pigs may be increased if diets contain excess Leu. Therefore, the objective of this experiment was to determine the optimum standardized ileal digestible (SID) Trp:Lys ratio in growing pigs fed diets with excess Leu from DDGS. A diet based on corn, soybean-meal, and 35% DDGS was f ...

I. INTRODUCTIONDietary electrolyte balance (DEB) is defined by the interrelationship between sodium (Na+), potassium (K+) and chloride (Cl-) where DEB = Na++K+ -Cl- as mEq/kg and it plays an influential role in homeostasis of the body fluids. Borges et al. (2004) investigated DEB in two experiments and concluded that there was a quadratic effect on weight gain and feed conversion efficiency (FCE) ...

INTRODUCTIONThe swine slaughtering process is affected by practices that go from the establishment of fasting on the farm to the slaughtering stage in the slaughterhouse. Animals are subjected to practices that will directly reflect on the quality of their carcass, and on how meat cuts will be ranked as more or less valuable in the market. Thus, pre-slaughter phases are fundamentally relevant to t ...
