Methane emissions from rams fed kikuyu hay or kikuyu-lotus hay mixture

Methane emissions from rams fed kikuyu hay or kikuyu-lotus hay mixture

Dietary inclusion of contain-tannin legumes may reduce enteric methane emission in ruminants. To evaluate methane emissions from sheep fed a kikuyu grass (Cenchrus clandestinus) diet partially substituted with lotus (Lotus uliginosus), twelve growing rams, with 23±2 kg average liveweight, were assigned randomly to two treatments and with three measurement periods in a switchover design. Treatments consisted of 100% kikuyu hay or 70% kikuyu hay: 30% lotus hay and with 6 rams per treatment. Each of three periods lasted 20 d, where the first 15 d were for acclimatization and the last 5 d for measurements. Rams were placed in metabolic cages and fed once a day (8 AM) at 90% of their voluntary feed intake, with free access to drinking water. Feed intake, fecal production and feed digestibility were determined at each period. Methane production was measured for each treatment group of 6 rams using the poly-tunnel technique. Legume addition reduced total methane production (27.6 vs. 23.1 g/animal; p<0.01), methane production per dry matter intake (DMI) (18.8 vs. 12.2 g/kg DMI; p<0.01), methane production per digestible OM (DOM) (36.1 vs. 23.4 g/kg DOM; p<0.01) and methane production per digestible NDF (DNDF) (43.5 vs 34.0 g/kg DNDF; p<0.01). In conclusion, lotus inclusion in pasture systems could be a suitable legume to reduce methane emissions in grazing systems.

La inclusión de leguminosas taníferas puede reducir las emisiones de metano entérico en rumiantes. Para evaluar la incorporación de lotus (Lotus uliginosus) a una dieta basal de kikuyu (Cenchrus clandestinus) sobre la emisión de metano en ovinos, doce corderos con peso vivo de 23±2 kg fueron asignados aleatoriamente a dos tratamientos en tres periodos de medición en un diseño de sobrecambio. Los tratamientos fueron 100% heno de kikuyo o 70% heno de kikuyo y 30% heno de lotus con seis corderos por tratamiento. Cada uno de los tres periodos tuvo una duración de 20 d, en donde los 15 d primeros días fueron de adaptación y los últimos 5 d de medición. Los corderos fueron ubicados en jaulas metabólicas, alimentados una vez al día (8 AM) al 90% de consumo voluntario y tuvieron agua a voluntad. El consumo, la producción de heces y la digestibilidad fue determinada para cada periodo. La producción de metano fue determinada para cada grupo de 6 corderos a través de la técnica del poli-tunel. La inclusión de leguminosa redujo la emisión de metano total (51.6 vs. 43.1 g/animal; p<0.01), metano respecto a la materia seca consumida (MSC) (18.8 vs. 12.2 g/kg MSC; p<0.01) y metano respecto a la materia orgánica digerida (MOD) (36.1 vs. 23.4 g/kg MOD; p<0.01). En conclusión, el lotus podría ser una leguminosa adecuada para reducir las emisiones de metano en sistemas pastoriles.
