|Title:||Efficiency of protein utilization in male and female broiler chickens||Contributor(s):||Li, Li (author); Nolan, John Vivian (author)||Publication Date:||2002||Handle Link:||https://hdl.handle.net/1959.11/4417||Abstract:||The efficiency of dietary protein utilisation in broiler chickens was studied by conventional balance techniques and by digestion and metabolism of ¹⁵N-labelled protein in the diet. Between 16 and 30 days of age, male chickens tended to be heavier and to ingest more feed than female chickens: however, female chickens tended to absorb and utilize dietary protein more efficiently than male chickens. Whole-body synthesis rate did not differ between sexes and was 6.7-7.5 times the protein absorption rate. Only about 10% of the protein synthesized was deposited in tissue gain whereas 90% was degraded. Fractional protein synthesis rates were determined from the decline in enrichment in small intestinal, liver and breast muscle samples taken sequentially from birds that had earlier ingested ¹⁵N-labelled feed. FSRs declined with age but did not differ between sexes and were 44-52, 23-29 and 15-18 %/d, respectively.||Publication Type:||Conference Publication||Conference Name:||Australian Poultry Science Symposium, Sydney, NSW, Australia, 11 - 13 February, 2002||Conference Details:||Australian Poultry Science Symposium, Sydney, NSW, Australia, 11 - 13 February, 2002||Source of Publication:||Proceedings of Australian Poultry Science Symposium, v.14, p. 175-178||Publisher:||Australian Poultry Science Symposium & Poultry Research Foundation & World's Poultry Science Association, Australian Branch||Place of Publication:||Sydney, NSW, Australia||ISSN:||1034-6260||Field of Research (FOR):||070204 Animal Nutrition||Socio-Economic Outcome Codes:||830309 Poultry||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Other Links:||http://www.vetsci.usyd.edu.au/apss/documents/2002/APSS2002-li-pp175-178.pdf
