31242854-2	2019	Cattle selected for low-RFI (feed efficient) have similar production levels but decreased feed intake, while also emitting less methane.	Methane	128-135	RFI	Bos taurus	24-27	
30197132-16	2018	When pre-experimental RFI was used as a continuous variable, higher methane per kilogram of DMI was found for cows with negative RFI than positive RFI values, but not for methane per kilogram of ECM.	Methane	68-75	RFI	Bos taurus	22-25	
30197132-16	2018	When pre-experimental RFI was used as a continuous variable, higher methane per kilogram of DMI was found for cows with negative RFI than positive RFI values, but not for methane per kilogram of ECM.	Methane	68-75	RFI	Bos taurus	129-132	
30197132-16	2018	When pre-experimental RFI was used as a continuous variable, higher methane per kilogram of DMI was found for cows with negative RFI than positive RFI values, but not for methane per kilogram of ECM.	Methane	68-75	RFI	Bos taurus	129-132	
25156936-8	2014	Compared with Group High RFI, the CH4 emission of Group Low RFI was significantly lower (on the basis g/d and g/kg DMI by 11% and 19%, respectively).	Methane	34-37	RFI	Bos taurus	60-63	
25156936-9	2014	Furthermore, the CH4 emission [g/d] was significantly correlated with RFI (r = 0.77).	Methane	17-20	RFI	Bos taurus	70-73	
22038990-7	2012	Selection for a decreased RFI phenotype can reduce feed intake, methane production, nutrient losses in manure, and visceral organ weights substantially in beef cattle.	Methane	64-71	RFI	Bos taurus	26-29
