Consumer-driven nutrient cycling has been shown to be an important process in supplying inorganic nutrients to autotrophic and heterotrophic organisms in aquatic ecosystems. Theory indicates that consumer nutrient excretion is influenced primarily by an organismâs nutrient composition; however, an organismâs diet should also play an important role in nutrient excretion, ...

One hundreds ninety two 30-week age White Leghorn (Hy-line W-36) laying hens ...

The effects of microbial phytase supplementation on growth performance, ileal digestibility of protein and ether extract, amount of excreted phosphorus and bone development was investigated in a 3 weeks trial using 192 mixed sex, day-old Ross 508 broiler chicks fed corn-soybean meal diet. The trial was set up according to ...

Feeding trials were conducted in glass tanks to assess the effect of toasting and incubation of soybean meal supplemented with phytase (Ronozyme P (5000) CT, Batch HB 955001) in practical diets on the growth, digestibility and mineral deposition in Nile tilapia, Oreochromis niloticus. The diets contained six levels of the ...

Aquafeed is a major source of phosphorus (P) that results in eutrophication and pollution of water-ways.

In previous studies, it has been found that 3% Na2CO3 added to a cariogenic diet raised the pH of the diet from 6.0 to 8.9 and also reduced its cariogenicity. The addition of lactic acid to the diet in an amount which lowered the pH to 4.7 did not make ...

Ectopic calcification is a frequent complication of many degenerative diseases. Here we identify the serum protein α2–Heremans-Schmid glycoprotein (Ahsg, also known as fetuin-A) as an important inhibitor of ectopic calcification acting on the systemic level. Ahsg-deficient mice are phenotypically normal, but develop severe calcification of various organs on a mineral ...
