“…La suplementación alimenticia en la producción ovina es una estrategia de mitigación de la baja oferta de forrajes en distintas épocas del año, en gran parte debido a que las producciones ovinas a nivel mundial están ubicadas en las zonas secas, predominantemente con baja disponibilidad forrajera y pasturas con pobres valores nutritivos (Iñiguez, 2011). Se ha observado que en las regiones tropicales existen una o dos temporadas de lluvias durante el año, y se prevé que los meses de junio y julio, y enero y marzo, presentan una disminución en la disponibilidad de forraje, lo que permite implementar planes de acción para evitar disminuciones en los índices productivos.…”

The sheep body measurements are useful indicators of type and function that allow improving the selection. Biometric studies have shown in sheep a relationship between these measures with some productive variables. The main purpose of this study was to evaluate the testicular development and their relationship with morphometric parameters on Colombian hairy sheep of Sampués, Sucre, Colombia. Weaned males (n=12) born between February and April of 2014 were used, and the following measures were taken every twenty-eight days: scrotal circumference (CS), body weight (PC), rump height (AG), withers height (AC), and right and left testicular length (LTD and LTL).The sheep were between three to twelve months old. A multiple regression analysis (RA) was done from PC; AG; AC; TL. To describe the variation of LT, the model included only the variables PC; AG; AC. The grade of association between the studied variables was performed by a Pearson correlation. Scrotal circumference showed a high correlation with the evaluated morphometric parameters. In the RA analysis, the PC influenced the variable CE (p<0.05), while other variables did not have a significant influence. According to the regression coefficient associated to the measurement, per each kg of PC that an animal gained in weight, there was a corresponding increase of 0,09 cm in the CS.

“…Participatory research promotes community involvement in both the analysis of its reality and in the search for alternative solutions to its production limitations (Mata, 2003;Freire, 1973;Fals-Borda, 1987). This contributes to the researcher's training, the formation of the community organization, and in a dynamic and participatory manner to the development of a portfolio of alternative projects (Schutter and Yopo, 1983), in which producers and researchers interact (Gonsalves et al, 2006) to obtain a technological change that improves farmers' living conditions (Iñiguez, 2011). This is necessary, especially when it comes to agricultural production systems in arid areas (Salinas et al, 1991) with specific characteristics (Arechiga et al, 2008), where adaptive research is required that results in greater productivity and thus increased application by the producer (Devendra, 2010).…”

“…La investigación participativa promueve la intervención de la comunidad, tanto en el análisis de su realidad como en la búsqueda de alternativas de solución de sus limitantes de producción (Mata, 2003;Freire, 1973;Fals-Borda, 1987). Esto contribuye a la formación del investigador, de la organización comunitaria, y en forma dinámica y participativa en la formulación de un portafolio de proyectos alternativos (Schutter y Yopo, 1983), donde interactúan productores e investigadores (Gonsalves et al, 2006) para obtener un cambio tecnológico que mejore la condición de vida de los productores (Iñiguez, 2011). Esto es necesario, en especial cuando se trata de sistemas de producción agropecuarios en zonas áridas (Salinas et al, 1991) con características específicas (Arechiga et al, 2008); donde se requiere investigación adaptativa que resulte en mayor productividad y así incremente su aplicación por el productor (Devendra, 2010).…”

RESUMENLa cabra se localiza en agroecosistemas frágiles. Con el propósito de evaluar el efecto de tecnologías aplicadas de manera participativa, en un marco de conservación de los recursos naturales sobre la productividad de pequeños rumiantes, se probaron seis tecnologías: 1) El pastoreo diferido rotacional (SPDR) logró 60 % de cubierta vegetal y 35 % pastoreo continuo (PAC); 996.5 vs. 280.8 kg·ha -1 de materia seca (P<0.01) y composición botánica de 59 especies vs. 27 en SPRD y PAC, respectivamente; 2) De 200 presas filtrantes construidas, hubo retenciones hasta de 212 t de suelo sedimentado en presas de 25.5 m de ancho; 3) Resiembras con nopal Amarilla Olorosa tuvieron una supervivencia de 90.7 %; 4) La siembra de cebada logró rendimientos (MS) similares al maíz con mayor proteína cruda; 5) La suplementación de cabras y cabritos (0-5 meses) con bloques nutricionales, incrementó el PV (P<0.001) en cabritos de parto doble (71.9 g·día -1 ), respecto a cabritos dobles (46.5 g·día -1 ) y cabritos sencillos (40.7 g·día -1 ) no suplementados; 6) Quesos de leche caprina y bovina no difirieron (P<0.05) en atributos valorados, logrando la participación de mujeres. El enfoque de sistemas participativos permitió diseñar actividades apropiadas, incrementando la productividad y promoviendo la conservación de recursos naturales. ABSTRACTThe goat is located in fragile ecosystems. In order to evaluate the effect of applied technologies in a participatory manner, within a framework of conservation of natural resources, on the productivity of small ruminants, six technologies were tested: 1) deferred-rotation grazing system (DRGS) achieved 60 % vegetation cover compared to 35 % for continuous grazing (CG); 996.5 vs. 280.8 kg . ha -1 of dry matter (P<0.01) and botanical composition of 59 species vs. 27 in DRGS and CG, respectively; 2) of 200 filter dams built, up to 212 t of soil sediment was captured in 25.5-m-wide dams; 3) reseeding with Amarilla Olorosa (fragrant yellow) prickly pear cactus had a 90.7 % survival rate; 4) sowing of barley achieved yields (MS) similar to corn but with higher crude protein; 5) supplementation of goat does and kids (0-5 months) with nutritional blocks increased live weight (P<0.001) in double birth kids (71.9 g . day -1 ) compared to unsupplemented double and single kids (46.5 g . day -1 and 40.7 g . day -1 , respectively); 6) goat and cow's milk cheeses did not differ (P<0.05) in measured attributes, achieving the participation of women. The participatory systems approach enabled designing appropriate activities, increasing productivity and promoting conservation of natural resources.

The transfer of animal genetic improvement strategies in the environments of resource-poor smallholder producers in developing countries has not been successful. Therefore, the access by farmers to sources of animals with high genetic potential is difficult or just not possible. As producers improve or intensify their systems to capture market opportunities, this access need is accentuated. This paper reviews identified constraints to the transfer of breeding plans, the need for a new approach, and the lessons learned in applying a better-targeted approach. The issues and thoughts were derived from the experience of a working group involving the International Center for Agricultural Research in the Dry Areas; Austrian University of Natural Resources and Life Sciences; Argentinean National Institute of Agriculture Technology; Brazilian Agricultural Research Corporation (Embrapa Goats and Sheep); and National Research Institute for Forestry, Agriculture and Animal Production-Mexico. The transfer of breeding strategies in smallholder systems is not a straightforward task. Contrasting a successful application in commercial livestock production environments, the achievement of the primary objectives in smallholder systems requires a holistic approach beyond pure technical matters. Of all identified aspects with direct incidence in the implementation of breeding plans, the lack of specific national policies coupled with long-term funding to support the improvement of smallholder production systems, and the lack of involvement and participation of the communities emerge as issues that gravitate more to achieve sustainability and meet the objectives of a given breeding plan.Key words: Breeding plan, policy, participatory approach, smallholder ABSTRAKStrategi transfer teknologi pemuliaan untuk perbaikan genetik ternak pada peternak kecil di negara berkembang belum berhasil. Oleh karena itu, akses petani terhadap potensi genetik berkualitas tinggi masih sulit. Dalam memperbaiki dan mengintensifkan sistem untuk membuka peluang pasar, maka produsen harus memperluas akses peternak kecil terhadap ternak unggul. Makalah ini mengulas kendala yang teridentifikasi dalam transfer strategi pemuliaan, kebutuhan akan terobosan baru yang lebih tepat sasaran. Isu dan pemikiran dirangkup dari pengalaman kerjasama
