“…The main source of income for 95.3 % of the interviewed farmers derives from agricultural production, whether exclusively from livestock (77 %), croplivestock (20 %) or cropping (3 %) production. Only in 4.7 % of the systems the main source of the income derives from activities unrelated to livestock production in concurrence with Mellado et al (2005) in a study conducted in the same region. In this study the types of systems did not differ on their main income sources (P>0.05).…”

“…Grazing mostly takes place in communal range lands (95 % of the cases); it is carried out by family members in particular by the family head, in agreement with Mellado et al (2005). Grazing starts at 10:00 h and ends at 18:00 h, time in which goats return to the corral for shelter.…”

“…Para el 95.3 % de los productores encuestados, la principal fuente de ingresos proviene de la producción agrícola, ya sea exclusivamente producción de ganado (77 %), cultivo/ganado (20 %) o cultivo (3 %). Sólo en 4.7 % de los sistemas la fuente principal de ingresos deriva de actividades no relacionadas con la producción de ganado, de acuerdo con Mellado et al (2005) en un estudio realizado en la misma región.

RESUMENSe llevó a cabo un estudio base en la Comarca Lagunera en el norte de México con el fin de evaluar el potencial para la implementación de un programa de mejoramiento. Se aplicó una encuesta a 64 productores, con el fin de documentar el sistema de producción. Se realizó una caracterización fenotípica de la población caprina; se registraron medidas corporales de 509 animales. El sistema se diferenció en insatisfacción de la producción, distancia a las áreas urbanas y tipo de trabajadores. La alimentación de los animales se basa en el pastoreo con una suplementación mínima. Las medidas corporales incluyen: altura a la cruz (77.0 ± 0.3 cm), circunferencia del pecho (87.0 ± 0.3 cm) y longitud del cuerpo (78.0 ± 0.3 cm), obtenidas hasta los 4 años de edad. Edad al primer estro = 6.9 meses, edad al primer servicio = 8.3 meses, intervalo entre partos = 1 año, longitud de lactación =7.4 meses y crías promedio por parto =6.3. La mayoría de los productores (40 %) evalúa a sus hembras en base a la producción y a los fenotipos (no se cuenta con un registro). El principal recurso para los machos se obtiene fuera del rebaño, sin considerar las características de adaptación y productividad. Todos los productores comentan que las cabras de raza europea con alto porcentaje de mejoramiento genético muestran problemas de adaptación. Se considera importante, un sistema basado en la comunidad, que permita un acceso a animales mejorados y que considere los objetivos de los productores. ABSTRACTA baseline study was conducted in the Comarca Lagunera in the North of Mexico to evaluate the potential for implementation of a breeding program. A questionnaire was applied to 64 producers to document the production system. A phenotypic characterization of the goat population was performed; body measurements of 509 animals were recorded. The systems differentiated in production intensification, distance to urban areas and type of employees. Animal feeding is based on grazing with minimum supplementation. Body measurements including: height at withers (77.0 ± 0.3 cm), chest circumference (87.0 ± 0.3 cm) and body length (78.0 ± 0.3 cm), increased until 4 years of age. Age of first estrus, age of first service, kidding intervals, lactation length and kiddings per doe averaged, respectively, 6.9 months, 8.3 months, 1 year, 7.4 months and 6.3 kiddings. Most (40 %) producers evaluate their females on production and phenotype basis, recording is not done. The main source of males is form outside of the herd, without consideration of adaptation and productivity traits. All producers expressed that goats with high percentage of genetically improved European breeds showed adaptation problems. A community-based system, that allows access to improved animals and which considers the producers' objectives, was considered important.

The objective of this study was to evaluate the effect of foraging on local scrubby rangeland versus stable feeding with high-protein concentrate as well as the compulsory pasteurization process on goats’ milk and artisan soft cheese quality in terms of chemical composition and fatty acid profile. The results indicated that there were no significant differences in the energy, fat, or ash content of milk and cheese due to feeding; however, a significant influence of feeding on cheese protein and fatty acids in both milk and cheese was detected. Feeding on scrubby rangeland tended to increase the amounts of major polyunsaturated fatty acids in milk and cheese from goats. Pasteurization, which is mandatory in Mexico, did not alter the fatty acid concentrations in milk or cheese. Small goat-keepers using rangeland resources might claim better economical returns for products recognized as healthier. Further investigations to assure ecosystem sustainability of shrubby rangeland joined with economical evaluations and best animal management to avoid deleterious effects are recommended.
