【题文】 A calorie is a unit of energy, not a measure of weight or nutrient density. The calories you see on nutrition labels,however,are actually kilocalories. The calories on food packaging always refer to kilocalories, even though it just says “calories”. One kilocalorie is the amount...
The impact of nutrient density in terms of energy and/or protein on live performance, metabolism and carcass composition of female and male broiler chickens of two commercial broiler strains. J. Anim. Physiol. An. N. 94:509-518.Delezie E, Bruggeman V, Swennen Q, Decuypere E, Huyghebaert ...

Relationship between dietary fiber and nutrient density and its effect on energy balance, egg yolk cholesterol and hen performance. Two experiments were conducted to determine the effect of dietary fiber in rations of varying nutrient density on egg yolk cholesterol, energy balance and ... R E,Var...

3). In poultry, feed ingredients are largely digested enzymatically, and because of the short GIT they require feed which has a greater energy and nutrient density compared to pigs and ruminants. Although microorganisms in poultry colonize the entire length of the GIT, the highest microbial ...
body mass index (BMI), percent body fat (fat), fasting blood glucose, fasting serum insulin levels, glycated hemoglobin (HbA1c), systolic and diastolic blood pressures, serum levels of total cholesterol, triglyceride (TG), high-density lipoprotein-cholesterol, uric acid, urea nitrogen, and creati...
Restriction of energy density and DMI by using low-energy forages, such as straw, is a good approach for controlling this problem. Alfalfa stems contain high fiber and moderate protein content and have the potential to be used to replace straw to reduce dietary energy. The objective of this ...
predictVcmaxfrom physical environmental variables: irradiance (photosynthetic photon flux density, PPFD) and temperature and CO2(ref.23). The ‘strong form’24of this hypothesis states that carboxylation and electron transport are co-limiting under typical daytime growth conditions, so that neither is ...
and the alkyl toO-alkyl ratio was used to provide an index of the decomposition potential of organic materials, with higher ratios indicating a greater decomposition potential90. Aggregate distribution was measured by a wet sieving and size-density fractionation approach91. In total, three aggregates...
