Improving feed efficiency (FE) reduces the environmental impact and increases the profitability of pig production. Despite the improvements in pig FE achieved in recent years1,2, it still takes~3.5 kg of feed to produce 1 kg of saleable pig meat2–4. Nutritional strategies can be implemented to improve FE; however, the impact of these strategies on the microbial composition of the g ...

I. INTRODUCTIONMetabolizable energy (ME), digestible amino acids (dAA) and available phosphorus (avP) are the largest and most expensive components in broiler diets, considerable fractions of which still pass through the digestive tract undigested and are lost via excretion (Ravindran et al., 2013), hence, emphasizing the need for higher nutrient usage efficiency than current practice. Ability of ...

I. INTRODUCTIONThe most important cost component of broiler feed relates to energy, as this may account for up to 75% of feed costs (van der Klis & Kwakernaak, 2008). Therefore, more accurate evaluation of feed energy in broiler production is imperative for environmental and financial reasons. The metabolisable energy (ME) system is currently the preferred measure for determining energy utilis ...

I think everyone in this discussion made good comments. It seems to me that all that is needed is an underlying theory to fit all the various pieces into. This is the same for phytase and all the other enzymes: First, it should be accepted that responses to enzymes follow Michaelis-Menten kinetics. Enzymes do not give linear responses. This was very nicely illustrated by Shirley and Edwards, Jr. ( ...

For sure enzyme responses are non-linear but in the range, we test them in animal nutrition they occasionally appear linear. I think it is crucial to also examine available/reactive substrate concentration when interpreting enzyme response. Systems may be saturated with the substrate in which case enzyme responses may be exaggerated across a wide range of inclusion concentrations, or they may be s ...
