“…Among the factors reported in the literature to maintain an agricultural system running, one nds education level. For the present study, this variable ranged between incomplete and complete elementary school (4-6 schooling years) that is lower than reports for other sheep producing regions in Mexico (Herrera et al 2019), and lower than the international mean (Tindano et al 2015; Voors and Haese 2010).…”

“…In Mexico, SSSPS have one of the best pro tability rates and growth prospects in the livestock sector (Martínez-González et al 2011) since their characteristics enable them to turn by-products and residues from unpro table harvests into useful human food with high nutritional and economic value (Wilkinson 2011;Herrera et al 2019). SSSPS are mostly located in states of central Mexico, which provide 35% of national production (SIAP 2019); and the region consumes 85% of the national demand (Rodríguez-Licea et al 2016).…”

The objective was to assess grazing as an element of profitability and competitiveness of a small-scale sheep production system (SSSPS) in central Mexico and compare its economic performance by means of an analysis of scenarios. A questionnaire was applied to 66 sheep farmers on technical variables, flock management, economic and social aspects. Two scenarios were analyzed to assess the contribution of grazing on profitability and competitiveness. The first analysis was when grazing was the feed base, and secondly, costs of opportunity and economic impacts were studied under the assumption that sheep do not graze and total feed has to be bought from feed vendors. In order to determine the differences between the farmers with the highest and lowest profitability indexes, a four-stratum stratification was made (stratum 1, between 6 and 35 sheep; stratum 2, 36 to 70 sheep, stratum 3 = 71 - 105 sheep; and stratum 4, 106 to 140 sheep). Quantitative variables (technical management, flock management and social aspects) were evaluated with analysis of variance, while qualitative variables were analyzed by means of a Kruskal-Wallis test. Production cost analysis and profitability index were assessed with the Policy Analysis Matrix. Differences were found between strata, farmers with more than 70 sheep have the best profitability indices and the least vulnerability before the non-grazing scenario. Grazing had a positive effect reducing the cost of production and increasing competitiveness in the four strata assessed. However, farmers with higher technical level, specialized breeds and larger flocks (strata 3 and 4) have higher economic profits.

“…En México la producción de ovinos y caprinos es una opción económica para enfrentar la pobreza en las zonas rurales, por la cantidad de ingresos y la cantidad de productores (4,5). En el caso de los ovinos, el inventario nacional es de 8.6 millones de cabezas (6), en 50,000 unidades de producción. Alrededor del 34% de los productores solo obtienen ingresos de la producción ovina.…”

Small ruminant production systems in Mexico and their effect on productive sustainability

et al. 2022

View full text Add to dashboard Cite

In the small ruminant sector, there is a great interest in measuring and improving their production systems and their environmental performance, since its great adaptability and inhabits a wide variety of ecosystems, with a great biodiversity of food resources, grazing in turn, generates economic-productive and environmental benefits. However, unplanned management and overexploitation of the natural resources of these areas have caused erosion, water depletion and even desertification, in the same manner intensive production systems and intensive agriculture that feeds these farming systems. To compare scientific innovations in the sustainability of the different production systems of small ruminants a bibliometric analysis was carried out to describe the advantages and disadvantages of the management of extensive, semi-intensive and intensive-stable production systems in the sustainability of small ruminants. There is concern in society about the environmental impact of animal production systems and that these have been carried out in a sustainable way. This trend influences the production of sheep, goats, and white-tailed deer, which are develop in intensive, semi-extensive and extensive systems. Due to the pressure to increase the volume and efficiency of production and to cope with demand, intensive systems are best suited, but face greater environmental such emission of greenhouse gases (GHGs), which contribute to global warming and animal environmental problems. On the other hand, semi-extensive and extensive systems also emit GHGs, however are associated with greater animal welfare and cleaner production. However, are affected by seasonal variations for forage production to maintain production levels.

“…La mayoría de la ovinocultura en México es desarrollada bajo sistema extensivo, también denominado tradicional, donde su alimentación se basa en el pastoreo a orilla de caminos vecinales y pastizales en zonas de conservación. Aunque también se cuenta con sistemas de alimentación mixtos, los cuales disponen de forrajes, entre ellos la avena (Avena sativa) y ebo (Vicia sativa), que son producidos en las tierras de los productores ovinos (Herrera-Haro et al, 2019), también presentan diferente nivel tecnológico, capacidad productiva y uso de recursos (Espejel-García et al, 2015).…”

Dinámica de la producción y consumo de carne ovina en México 1970 a 2019

2021

Introducción. El volumen de producción de carne de ovino en México no satisfizo la demanda, principalmente para la elaboración del platillo tradicional “barbacoa”. Objetivo. Evaluar la dinámica de la producción y consumo de carne de ovinos en México. Materiales y métodos. La información estadística se obtuvo a partir de publicaciones oficiales de México del año 1970 al año 2019. Se determinaron los incrementos/decrementos, la tasa de crecimiento media anual, se calculó el índice estacional con el método de porcentajes promedios. Los datos de cada mes se expresaron como porcentajes del precio y de la producción. Resultados. La producción de carne en canal de ovino de 1970 a 2019 tuvo una tasa de crecimiento media anual de 2,2 %, en 2019 la producción fue 64 030 toneladas; la carne de ovino pagó mejor (USD por kg) en comparación con otras especies pecuarias. En 2019 los precios pagados fueron 1,47, 1,69, 1,54, 1,34 y 1,08 de ovinos (Ovis aries), bovinos (Bos taurus), caprinos (Capra hircus), porcinos (Sus scrofa) y pollos (Gallus gallus domesticus), respectivamente. El índice de estacionalidad para la producción de ovinos en pie, mostró que los meses de enero a mayo fue cuando se tuvo la menor producción (<100) y de junio a diciembre se dio la mayor (>100). La variabilidad del índice de la estacionalidad de los precios en carne de ovinos fue de 99,1 hasta 100,7 %, para este índice fue muy baja la variación (1,6 %), esto significó un precio estable todo el año; el consumo per cápita en México pasó de 467 a 567 g de 1970 a 2019. Conclusión. Existió una marcada estacionalidad en la producción; sin embargo, el precio se mantuvo constante a través del año, debido a que las importaciones estabilizaron el precio en la época de poca producción en México.
