“…Thus, it was expected that the population and activity of rumen microorganisms would increase, in turn increasing the digestibility of feed containing rice straw. This agrees with [6] results, who found that Gliricidia sepium increases digestibility of agricultural waste-based rations. Furthermore, [20] stated that increasing levels of Gliricidia sepium supplementation in low-quality feeds increases the rate of feed degradation, thus G. sepium supplementation may increase consumption and providing organic material that is easily degraded.…”

“…Hence, it is necessary to supplement it with a soluble protein from legume, e.g., Gliricidia sepium. Gliricidia sepium have 15-30% protein content [4], making them suitable to use as a feed supplement in waste-based feeds [5,6]. It also contains sufficient amounts of minerals (except phosphorus and copper) to meet the needs of livestock in the tropics [7].…”

Rice straw as ruminant feed has low digestibility makes ruminants difficult to digest. Since ammoniated rice straw can increase its digestibility, it is necessary to supplement it with Gliricidia sepium. This research aimed to determine the effect of Gliricidia sepium supplementation on decreasing methane gas production and improving nutrient digestibility in complete ration with ammoniated rice straw. The treatments of this research were: A = 40% ammoniated rice straw + 60% concentrate, B = 40% ammoniated rice straw + 50% concentrate + 10% Gliricidia sepium, C = 40% ammoniated rice straw + 40% concentrate + 20% Gliricidia sepium, D = 40% ammoniated rice straw + 30% concentrate + 30% Gliricidia sepium. This research showed supplementation of G. sepium significantly decreased methane gas production from 27.22 mM to 13.13 mM and the number of protozoa from 6.3 x 105 cell/ml rumen fluid to 4.7 x 105 cell/ml rumen fluid. Gliricidia sepium supplementation increased digestibility significantly (P < 0.05). Digestibility of dry matter increased from 58.83% to 68.54% and digestibility of organic matter also increased from 59.50% to 69.50%. Total VFA (Volatile Fatty Acid) concentration did not differ significantly (P > 0.05) among treatments. Higher levels of G. sepium supplementation increased N-NH3 concentration from 7.33 mM to 10.50 mM and microbial protein synthesis from 74.33 mg/100ml rumen fluid to 108.25 mg/100ml rumen fluid. The treatment had a significant effect (P <0.05) on propionate production and the ratio of acetate: propionate. It can be concluded that 30% of Gliricidia sepium supplementation decreased methane gas production and the number of protozoa. Besides, 30% of Gliricidia sepium supplementation increased digestibility and rumen fermentation.

“…El contenido de lignina en L. leucocephala encontrado fue alto, sin embargo esta dentro de los rangos sugeridos por la FAO. La cantidad de lignina presente en la L. leucocephala de este ensayo, afectó directamente su digestibilidad y seguramente los componentes de la ración, reduciendo el aprovechamiento de energía (38,39) . El Cuadro 3 expresa los parámetros de la producción de gas total y sus volúmenes fraccionales a las 8, 24 y 72 h de fermentación.…”

Se evaluaron mediante la técnica de producción de gas in vitro, fuentes energéticas locales (melaza, Zea mays L. y Musa paradisiaca L.) sobre la fermentación ruminal y producción de metano de diversos forrajes usados en un sistema silvopastoril con Panicum maximum cv. Tanzania, Gliricidia sepium (Jacq.) y Leucaena leucocephala cv. Cunningham, con ovinos. Se usaron cinco borregos Pelibuey x Katahdin 40 ± 3 (μ±DE) kg como donantes de líquido ruminal. Se analizaron cinco tratamientos (dietas) con diferentes mezclas de follaje de arbóreas y fuentes energéticas en un diseño experimental completamente al azar. M. paradisiaca y Z. mays presentaron los mayores registros de volumen (V) máximo en producción de gas (544 y 467 ml/g-1 MS, respectivamente) (P≤0.05). El follaje de G. sepium y L. leucocephala tuvieron los menores valores de V (253 y 180 ml/g-1 MS, respectivamente) (P≤0.05). La dieta D4 GMP (48 % P. maximum, 30 % G. sepium, 7 % Zea mays, 15 % M. paradisiaca) registro el mayor valor de V. No hubo diferencia (P>0.05) en la producción de metano en las dietas usadas, teniendo un rango de 6.31 a 9.60 de LCH4/kg MSDIG. Se generó un índice de emisión potencial de gases fermentables (IPEGF), el cual sugirió que dietas con carbohidratos de lenta fermentación, contribuyen a un índice más alto de emisión de gases. Por su mejoramiento en la calidad de las dietas y en contribuir en una baja de emisiones de CH4, se sugiere el manejo de arbóreas forrajeras como G. sepium y L. leucocephala, incorporando fuentes energéticas locales.

“…(2017) and Piñeiro-Vázquez et al . (2017) estimated that trees’ fruits and foliage ( Bursera Simaruba, Enterolobium cyclocarpum, G. sepium, L. Leucaena ) in optimal doses can mitigate between 21–37% of ruminal CH 4 . Indirectly, these fruits and foliage helped to reduce the use of off-farm fodder (previous chapter) and consequently also reduced GHG emissions.…”

Agro-Ecosystem Services Assessment of Silvopastoral Experiences in Chiapas, Mexico: Towards a Methodological Proposal

SUMMARYIn response to the current needs of humanity with regard to food production, environmental disasters and climate change, it is important to define (livestock) production systems and management practices that are both productive and ecologically sustainable. We qualitatively assessed advanced silvopastoral experiences in five ecologically and culturally distinct regions in Chiapas, Mexico, given their ability to provide key services: internal (productivity and productive resiliency) and external (climate change mitigation and biodiversity conservation). We propose 20 indicators that reflect management, resources, use of external inputs, availability of food, commercial products and animal feed and trees in grazing and forest areas. Sets of some indicators form criteria for dependence on external inputs, productive diversification with emphasis on food security, soil conservation, tree cover and landscape connectivity, among others. Indicators and thresholds were adjusted to critical (traffic light) levels, based on field data. Comparing the levels reached by the studied experiences, we found that most of the resulting services go hand in hand; so ‘win–win’ situations are possible to be achieved. The elements and practices that affect both internal and external services were explored. The red light critical points in each production unit were identified so that they could be attended. Experiences that presented higher levels in assessment criteria could serve as examples to enable the improvement of livestock systems under similar conditions. We propose this assessment as a tool for rapid intervention that can be widely applied to livestock systems, from conventional to organic or diversified, because of the criteria used. However, it can be more flexible, as new criteria can be added and thresholds can be adjusted for other types of production systems, always reflecting local and desired conditions. The proposed indicators can be also used as a basis for a quantitative agroecosystem assessment.
