Mohammad Hosein Shahir I agree with this position especially in rations where phytase is not added

Mohammad Hosein Shahir Dear Mohammad, you are absolutely right! form my practical experience, if I use effective phytase against high phytate feed content, it is necessary to add more Ca to avoid imbalance! The excess of phosphorus, released by phytase, resulted to decrease egg shell quality. The best way to solve these problem is to use mogern software like Korm-Optima (Russia, Voronezh). And of ...

bad pellet quality and feed toxicity

INTRODUCTIONLeucine (Leu) is a branched-chain amino acid (BCAA) that is essential for poultry species. It is one of the most potent amino acids regarding its effects on protein synthesis and degradation, energy balance regulation, modulation of insulin secretion, a nitrogen donor for muscle production and a critical regulator to initiate the translation and protein synthesis (Antony et al., 2002; ...

INTRODUCTIONAscites or pulmonary hypertension syndrome (PHS) is one of the main causes of mortality in modern broilers. It is estimated that ascites incidence may be as high as 20% of total mortality in broilers [1]. Due to selection for rapid growth, broiler chickens have a high metabolic rate and hence higher oxygen requirements. However, they have a marginal capacity of lung and cardiovascular ...

INTRODUCTIONThe rapid growth of modern broilers in a relatively short period of time requires a parallel increase in the size or capacity of supply organs, such as those of the cardiovascular and respiratory systems. However, due to the slower development of these organs relative to body growth rate, the capacity to balance body energy is compromised, particularly under extreme environment conditi ...

The adverse effects of excess Leu have been demonstrated mainly in diets containing marginal or deficient levels of Val and Ile.

When the levels of valine and isoleucine are above their minimum requirements in the practical diets, it is unlikely to observe the performance reduction in broilers due to Leu excess and BCAA antagonism.

we added 5 dietary synthetic leucine levels to a basal diet containing adequate valine and isoleucine. Performance improved by almost 8%. I can send the article. please email me: shahir_m@znu.ac.ir.

Dear Oscar Briceño
We just increased dietary leucine levels in valine and isoleucine sufficient diets. Recent research have shown that the antagonism between leucine and branched chain amino acids occurs in high leucine and low valine or isoleucine diets. Our experimental ration had enough valine and isoleucine according to Aviagen ( Ross 308) recommendations.
