“…In recent years, studies have been conducted in Peru to measure enteric CH 4 emissions with camelids or cattle [ 21 , 23 , 32 , 33 ] and although their results vary, all authors agree on the relationship between CH 4 emissions and nutritional compounds such as fiber, which can be significantly affected in the dry season [ 34 ]. These in vivo results are not different from those obtained in this experiment conducted under controlled conditions, where 7 of the 8 species evaluated showed higher CH 4 production during the dry season.…”

The present study aims to establish the relationship between chemical composition and in vitro methane (CH4) production of high Andean grasses. For this purpose, eight species were collected in dry and rainy seasons: Alchemilla pinnata, Distichia muscoides, Carex ecuadorica, Hipochoeris taraxacoides, Mulhenbergia fastigiata, Mulhenbergia peruviana, Stipa brachiphylla and Stipa mucronata. They were chemically analyzed and incubated under an in vitro system. Species such as A. pinnata and H. taraxacoides were characterized by high crude protein (CP. 124 g/kg DM) and low neutral detergent fiber (NDF. 293 g/kg DM) contents in both seasons, contrary to Stipa grasses. This same pattern was obtained for H. taraxacoides, which presented the highest values of gas production, organic matter digestibility (DOM), metabolizable energy (ME) and CH4 production (241 mL/g DM, 59% DOM, 8.4 MJ ME/kg DM and 37.7 mL CH4/g DM, on average). For most species, the content of CP, acid detergent fiber (FDA) and ME was higher in the rainy season than in the dry season, which was the opposite for CH4 production (p ≥ 0.05). In general, the nutritional content that most explained the behavior of CH4 production was the NDF content (R2 = 0.69). Grasses characterized by high NDF content produced less CH4 (R = −0.85).

“…La distribución al entorno natural del CH4 tiene un efecto perjudicial para la atmósfera, debido a su efecto invernadero (García-González et al 2008;Castelán-Ortega et al 2014;Liu et al 2018) y aunado a esto, representa una pérdida de energía (contenido bruto de 55.22 MJ kg -1 ) dietética para los animales rumiantes (2 -12 %) por lo que representa el principal gas de efecto invernadero en las granjas (Martin et al 2016). De acuerdo con Salas-Riega et al (2022), la actividad agropecuaria es responsable del 12-22 % de gases efecto invernadero y el ganado de leche contribuye con el 40 % de las 8.1 Gt de CO2e al año emitidas por este sector. Se ha mencionado que, desde el aumento del metano en la revolución industrial, la temperatura ha aumentado 0.31 °C y hoy en día el efecto invernadero ocasionado por este gas 25 veces mayor que el del CO2 (Liu et al 2018).…”

“…En este tenor, se ha propuesto al pastoreo como posibilidad para disminuir la intensidad de emisión de metano por kg de leche producido (Carrillo-Hernández et al 2020) y de acuerdo con Meale et al (2012), mejorar la calidad del forraje mediante la suplementación de plantas alternativas tiene potencial de disminuir las emisiones de CH4 por kg de producto animal, dado un mayor aprovechamiento de la dieta y un lapso más corto de alimentación. Sin embargo, el manejo de la alimentación de los pequeños productores es heterogéneo; varía según la localidad, la zona agroecológica y la condición socioeconómica según lo que tengan a su disposición en determinada época del año (Salas-Riega et al 2022); por lo que también se propone el uso de cereales de grano pequeño como opción forrajera en estos sistemas, dadas sus características como ciclo productivo corto y resistencia a la baja precipitación pluvial con un gran rendimiento de materia seca (MS) (Vega-García et al 2021), además de que, como mencionan Eckard et al (2010), al cambiar de pastos C4 a C3 se puede reducir la producción de CH4.…”

Background: Given the demand for meat and milk, it is necessary to increase the productivity of ruminant animals, nevertheless livestock also contributes to climate change due to annual methane (CH4) emissions, having a detrimental effect on the atmosphere, due to its effect greenhouse and also represents a loss of dietary energy for ruminant animals. Objective: The objective was to evaluate the nutritional quality in vitro, as well as the production and estimation of methane of small grain cereals in small-scale milk production systems, through two experiments. Methodology: In experiment 1, twelve dairy cows were compared through continuous grazing (6 h/d) in a 3x3 Latin square design, replicated three times with three 14-d experimental periods and three small-grain cereals: rye (Secale cereale) (CEN), wheat (Triticum aestivum) (TRG) and triticale (Triticosecale Witt.) (TRT), in addition the cows were supplemented with 4.5 kg DM/cow/d of commercial concentrate. In experiment 2, six cows grazing continuously (8 h/d) on a kikuyu grass (Cenchrus clandestinus) pasture were used in a double reversible design with the inclusion of 10 kg DM of rye silage (ECE) or rye silage. triticale (ETR), in addition the cows were supplemented with 3.6 kg DM/cow/d of commercial concentrate; this experiment also had three 14-d experimental periods. Forage (for chemical composition) and milk samples were taken at the end of each experimental period. Results: In experiment 1, the nutritional composition presented a high quality (mean of 145 and 740 g/kg DM, for CP and IVDMD, respectively), on the other hand, for experiment 2 the quality was medium-low (mean of 76 and 653 g/kg DM, for CP and IVDMD, respectively) regarding the fermentation parameters obtained through the in vitro gas production technique, as well as the methane production of the forages and the estimation of enteric CH4 production. No significant differences (P>0.05) were detected between the evaluated treatments. Implications: The results of this work provide information on the role that small grain cereals can play in methane emissions, in these production systems according to their nutritional value. Conclusions: in Experiment 1, it is concluded that rye, wheat and triticale are viable options to obtain medium-quality forage suitable for grazing, presenting enteric methane emissions, as well as moderate emission intensity, similar to those produced by quality pasture grazing. Regarding Experiment 2, both rye silage and triticale silage are presented as options to be used in these milk production systems in winter, without greatly increasing enteric methane emissions.
