Impact of Rumen Microbes on Feed Efficiency

Impact of feed efficiency and diet on adaptive variations in the bacterial community in the rumen fluid of cattle Assessment of the microbial ecology of luminal methanogens in cattle with different feed efficiencies Characterization of variation in rumen methanogenic communities under different dietary and host feed efficiency conditions, as determined by PCR-Denaturing Gradient Gel Electrophor...

Feed Efficiency Opportunities with 2008 Feed Cost

With the milk to feed ratio at 2.36 in February, 2008, dairy managers must carefully reviewing feed inputs relative to milk yield. A milk to feed ratio under 3 is a signal to reduce feed inputs. Feed efficiency (also referred to as milk performance efficiency and dairy efficiency) can be defined as pounds of 3.5%FCM (fat corrected milk) produced per pound of dry matter (DM) consumed. Monitoring...

Priority Area Review : Feed Grains & Feed Efficiency

Feed efficiency and mitochondrial function.

Studies have been conducted in our laboratory to assess differences in mitochondrial function and biochemistry in male broilers with high and low feed efficiency (FE) from the same genetic line and fed the same diet. Mitochondria obtained from broilers with low FE exhibited greater uncoupling of the electron transport chain (ETC) that was apparently due to site-specific defects in electron tran...
