Experiments were conducted to estimate daily N maintenance requirements (NMRs) and the genetic potential for daily N retention (NRmaxT) of pullets in growth phase. Three nitrogen balance trials were conducted, and a total ...

The objective of this experiment was to determine the protein requirements for hen pullets from 1 to 18 weeks of age, by factorial method, using the nitrogen balance and the comparative slaughtering techniques. Protein ...

Short-term nitrogen-balance response to traded intakes of a vegetable mixed-protein diet and to a milk-egg protein diet was tested in eight healthy male children aged 12-14 y. They received 72, 104, 136, and 168 mg N · kg ...

The present work aims to describe the nitrogen (N) budget in integrated aquaculture systems with Nile tilapia (Oreochromis niloticus) and Amazon River prawn (Macrobrachium amazonicum) in earthen ponds, with and without the ...

Part of the nitrogen (N) fertilizer applied to crops is lost to the environment, contributing to global warming, eutrophication, and groundwater contamination. However, low N supply stimulates soil organic N turnover and ...

The objective of this work was to determine the crude protein requirements for broiler breeder pullets, using the factorial method. The protein requirements for maintenance were obtained by comparative slaughter technique ...
