Identification of a metabolomic signature associated with feed efficiency in beef cattle

tailieu.vn

Identification of a metabolomic signature associated with feed efficiency in beef cattle. Animals with better ability to convert food into animal protein, measured as a trait called feed efficiency (FE), also produce less manure and greenhouse gas per kilogram of produced meat. Thus, the identification of high feed efficiency cattle is important for sustainable nutritional management.

A comparative analysis of the transcriptome profiles of liver and muscle tissue in pigs divergent for feed efficiency

tailieu.vn

Feed is a major economic consideration within the pig industry and accounts for 60–70% of the total produc- tion cost. On a different theme, variation in the immune responses has also been identified as a factor influencing feed efficiency [4, 8, 9].. Irrespective of the underlying biological processes con- tributing to RFI, early life predictors of feed efficiency would be a valuable, as the measurement of individual feed intake is not feasible in commercial production.

Background: Genetically selected modern broiler chickens have acquired outstanding production efficiency through rapid growth and improved feed efficiency compared to unselected chicken breeds. Recently, we analyzed the transcriptome of breast muscle tissues obtained from modern pedigree male (PeM) broilers (rapid growth and higher efficiency) and foundational Barred Plymouth Rock (BPR) chickens (slow growth and poorer efficiency).
