“…Irrespective of diets, the overall mean CH 4 emission was 255.01 L/day and 182.63 g/day. These values are consistent with the earlier observations of 165 (Shibata and Terada, 2010) or Molina et al (2016) reported 148 g/d in dairy heifers and variation observed in methane production among different studies could be attributed to feed quality, diet composition and individual animals. Sherasia et al, (2016) indicated that feeding nutritionally complete diets reduced (P<0.01) enteric methane emission (258.7 and 221.0 of g/d) after feeding in dairy cows, and Mohini and Singh (2010) found that lower methane production when fed complete diet to dairy cattle (197.4 versus 223.4 g/d).…”

The objective of this study was to determine the effect of feeding two fermented total mixed ration (FTMR) on methane production in dairy heifers. Four Holstein Friesian dairy heifers with mean body weight (BW) of 301.1 ± 42.2 kg were used in a simple cross-over design trial. Treatments consisted of 2 FTMR formulated to yield either low (LMD) or high CH 4 production (HMD). No differences were observed in dry matter intake (DMI; 6.49 and 6.19 kg/d), BW change (-3.37 and -7.25 kg), or DM digestibility (50.64 and 46.99%) between diets. Ruminal pH, total volatile fatty acids (TVFA) and molar proportions of acetate, propionate and butyrate were not different among diets. Concentrations of blood glucose were higher (P=0.05) for HMD compared with LMD at 2 h post feeding; however, blood urea nitrogen was not different. Methane emissions were 236.32 L/d for LMD and 273.70 L/d for HMD and not different. Feeding the FTMR differing in CH 4 potential did not affect DMI, digestibility, ruminal TVFA production or molar proportions of VFAs in dairy heifers.

“…En varios estudios se evidencia la capacidad de los SSPi basados en L. leucocephala para reducir las emisiones de GEI en sistemas bovinos orientados a la producción de carne y leche. Estas determinaciones incluyeron la producción de CH4 por fermentación entérica in vivo (Molina et al 2015;Molina et al 2016) y in vitro (Rivera et al 2015a), determinación de huellas de carbono, medición de los flujos de gases provenientes de praderas y excreciones bovinas, así como el balance de GEI (Naranjo et al 2012, Rivera et al 2015a, Rivera 2015b.…”

Reducir la vulnerabilidad a los desastres, adaptar los sistemas de producción agropecuaria a los cambios ambientales y mitigar las emisiones de gases con efecto de invernadero son acciones urgentes para enfrentar el cambio climático. En ganadería bovina de pastoreo, la investigación aplicada realizada en empresas y familias pioneras de varios países, ha permitido notables avances en agroforestería, especialmente con el sistema silvopastoril intensivo (SSPi), un uso de la tierra caracterizado por aplicar simultáneamente varios principios agroecológicos orientados a la maximización de la transformación de la energía solar en biomasa, la fijación biológica del nitrógeno, la solubilización del fósforo, la acumulación de materia orgánica en el suelo, el pastoreo rotacional, el uso inteligente del agua, la conservación de la diversidad biológica y el bienestar animal. Con estos arreglos, en los SSPi se aumenta la carga animal hasta cuatro o cinco veces en comparación al pastoreo extensivo pasando de 200 hasta 800-1200 kg ha-1 año-1, a la par que se reducen los costos en sistemas intensivos al reemplazar el alimento concentrado (40% en vacas lecheras tropicales) y evitar el uso de fertilizantes nitrogenados (bajan de 300 ha-1 año-1 de N2 hasta cero). La producción de carne y leche por hectárea se incrementa ostensiblemente sin aumentos en las emisiones de metano entérico ni aumentos en las emisiones de óxido nitroso. De esta manera, la implementación de SSPi permite intensificar sosteniblemente la producción de carne y leche bovina en el trópico y subtrópico.

“…Secondly, legumes can reduce enteric CH4 emissions from ruminants (Harrison et al 2015) and increase the levels of nitrogen (N) in the soil through biological N fixation (Dubeux et al 2017). For example, studies show that, when Leucaena leucocephala is sown into grass pasture, CH4 emissions per kg of consumed dry matter can be reduced by 15% (Molina et al 2016) and more than 75 kg N/ha/yr can be fixed (Shelton and Dalzell 2007). Other environmental benefits include: the improvement of soil fertility and carbon accumulation (Rao et al 2015); the potential for mitigation of and adaptation to climate change (Schultze-Kraft et al 2018); and a contribution to rehabilitating degraded pastures (Plazas and Lascano 2006).…”

Keynote paper presented at the International Leucaena Conference, 1‒3 November 2018, Brisbane, Queensland, Australia.Despite the great potential of legumes in cattle production, their adoption and use throughout the tropical world remain limited. While this is largely attributed to factors such as limited knowledge or access to credit, lack of information on the viability and profitability of the technology can influence the adoption decision. The objective of this study is to evaluate the profitability of including Leucaena diversifolia, accession ILRI 15551 in a Colombian beef cattle production system. For this purpose, we use data from a grazing experiment comparing a grass-legume association (Brachiaria hybrid cv. Cayman and L. diversifolia) with a grass monoculture (cv. Cayman) in the Valle del Cauca department, both with the purpose of beef production. We use a discounted cash flow model, developed with the simulation software @Risk, which considers inherent risk and uncertainty factors in these types of rural investment projects, under three different pasture degradation scenarios. The results indicate that the inclusion of L. diversifolia is financially profitable and substantially improves the associated risk and performance indicators. Profitability indicators increased in a range of 15‒110%, and the probability of suffering economic losses decreased from 72% to 0%. The results were directly related to the increases in animal productivity (49%) and efficiency resulting from including the legume. This work shows that L. diversifolia has significant potential to increase both animal production and profitability, which is conducive to the sustainable intensification of beef production in grazing systems.
