Endogenous losses of nutrients

Endogenous losses of nutrients.

(2) (3) These are not presented in the form of practical allowances. Hence, in practice, safety margins will be allowed to take account of such factors as variations in availability of nutrients in different samples of feeding-stuffs, possible losses during manufacture and storage of food, breed and individuality of animals, environmental circumstances and standards of husbandry. livestock has ...

Quantifying Losses of Plant Nutrients and Elements during Windrow Composting of Various Feedstocks

The viability of composting as a practical alternative for disposal of the large quantities of organic wastes generated by municipalities, industry and agricultural procesSing depends, to a large degree, on adequate local markets for fished compost. In m y areas, the use of composts as soil ameadments in nearby agridtural fields offqs a large potential mark&. The benefits of adding stabilized o...

Ammonia and Methane Emission Factors from Cattle Operations Expressed as Losses of Dietary Nutrients or Energy

The objective of this study was to conduct a systematic review of published literature on ammonia (NH3) and enteric methane (CH4) emissions from beef and dairy cattle operations to obtain statistically representative emission factors based on dietary intakes of nutrients or energy, and to identify major causes of emission variations. NH3 emissions from lagoon or other manure storage facilities ...

Role of luminal nutrients and endogenous GLP-2 in intestinal adaptation to mid-small bowel resection.

To elucidate the role of luminal nutrients and glucagon-like peptide-2 (GLP-2) in intestinal adaptation, rats were subjected to 70% midjejunoileal resection or ileal transection and were maintained with total parenteral nutrition (TPN) or oral feeding. TPN rats showed small bowel mucosal hyperplasia at 8 h through 7 days after resection, demonstrating that exogenous luminal nutrients are not es...
