fully agree with the line of arguments of Tahir Naseem, however, the words he uses to define the "form" of an element limit the possibility of further development of research in this direction.1. 1. The terms "organic or inorganic": the term organic is applicable only to compounds of elements and is not applicable to individual elements. Thus, Cu, Zn, Na, Ca, P, N, O are elements and they cannot b ...

Copper (Cu) is a vital element involved in cellular metabolism and enzyme systems. At levels greater than nutritional requirements, dietary Cu addition enhances growth performance as a growth promoter (Pesti and Bakalii, 1996). Copper dosing at levels up to 250 mg/kg feed has been shown to improve intestinal structure and function, and alter the intestinal microbiota profile (Di Giancamillo et al. ...

I. INTRODUCTIONThe move towards lower protein diets in the UK has been driven by several factors over the last 20 years or so. In the early 1990’s the transition was made to formulating using digestible amino acids rather than total; this immediately gave a reduction in protein content and was, in hindsight, a useful cost reduction and performance improving step. By 1996, though, the challen ...

1. IntroductionFeed materials, such as wheat and maize, are known to be major variables when formulating poultry diets, as their nutrient profile and quality are often inconsistent and deviate from default values used by feed formulation software [1]. Additionally, the feed industry has access to a wide range of feedstuffs and the use of a particular ingredient will often depend on its cost, sinc ...

IntroductionRecently, higher dietary arginine (Arg) levels than the recommended values in nutritional tables have been reported (Murakami et al. 2012; Xu et al., 2018; Zampiga et al.,2018; Oliveira et al., 2022). This suggests that Arg levels needed for maximum performance are increased in modern broilers. The high dietary Arg levels found in the literature may be associated with the critical role ...

An increase in dietary phytate concentration may limit the availability of both phosphorus (P) and calcium (Ca) as a result of the progressive formation of Ca-phytate complexes along the gastrointestinal tract (Selle et al., 2009). However, inconsistent results were reported regarding the impact of phytate on P and Ca release in the presence of phytase with broilers, presumably due to the differen ...
