Abstract
Bacteria in low moisture environments are not favorable for growth, but can survive and cause a possible food safety risk for consumers. A study was conducted to evaluate survivability of Escherichia coli and storage stability of commercial powdered goat milk (PGM) products. Three batches of whole milk PGM samples were purchased at a local outlet, and divided into two halves to assign non-inoculated control and E. coli inoculated groups, then stored at 4 and 22°C for 0, 2, and 4 months. Results showed that significant reduction (P<0.05) in E. coli counts occurred at 22°C treatment group by more than 2 log CFU/g at 2 months storage, then further decreased by an additional 0.37 log CFU/g at 4 months storage. The survival of E. coli was significantly higher at 4°C, suggesting that E. coli could survive better at 4°C by extending a longer latent period than at higher temperature (22°C) under the low water activity condition. E. coli counts had negative correlations with water activity at both temperature treatments for all three storage periods except for 0 and 2 months at 22°C, indicating that the survivability of the E. coli would decrease in powdered whole goat milk for 4 months of storage because of decrease in water activity. It was concluded that Escherichia coli survival and storage stability of the commercial PGM products were significantly (P<0.05) affected by storage temperature and time. READ MORE...

![]() Resumen El Chicamocha Medio es una ecorregión donde la caprinocultura se considera una actividad económica importante para las familias campesinas, por ello se propuso identificar las prácticas de manejo del ganado caprino para generar información específica que sea útil para las instituciones en diferentes escenarios. Se tomó una muestra no probabilística a 33 unidades productivas caprinas de nueve municipios de esta región. El diagnóstico se realizó mediante una encuesta semiestructurada sobre como: 1. tipificación de predios, 2. acompañamiento técnico, 3. inventario de semovientes, 4. instalaciones para caprinos, 5. fin productivo, 6. manejo del rebaño, 7. Plan sanitario, 8. tipo de sistema productivo y alimentación y 9. Bioseguridad. Se estableció que la caprinocultura se desarrolla en minifundios con un inventario promedio de 59 cabezas, con infraestructura adaptada y baja inclusión tecnológica. El fin productivo predominante es la carne, su manejo es tradicional en sistema semi confinado y el principal problema sanitario referido es el parasitismo gastrointestinal. Se concluye que el manejo del rebaño es tradicional con baja inclusión tecnológica, los problemas sanitarios son de origen infeccioso y las soluciones ofrecidas a este renglón productivo son muy incipientes.

La metodología fue descriptiva con variables cuantitativas y muestreo por conveniencia, la información se recopilo por observación y encuestas semiestructuradas de aplicación directa, y luego mediante la técnica de paneles de productores se validó. El desconocimiento de estos parámetros limita la eficacia en la toma de decisiones de los productores, incidiendo directamente en el desarrollo de la cadena, evidenciándose en las falencias existentes en la gestión administrativa y de mercados.

The Department of Animal and Dairy Sciences is seeking an Assistant Extension Professor for a 12-month tenure track (60% extension/40% Research) position to develop a swine management extension program and a research program that emphasizes swine growth and development and/or fresh or processed pork production. The Animal and Dairy Sciences Department currently houses approximately 380 undergraduate students, 20 graduate students, and 22 faculty, both on campus at research and extension centers throughout Mississippi. The Department conducts teaching, research and extension activities on the 1200 acre south farm which includes a small research swineherd and research pens for over 150 animals. Also, proximity to commercial swine facilities in the Southeast will increase research and extension opportunities for the successful candidate. The Department began operations on a new 15,000 ft2 Meat Science and Muscle Laboratory in July of 2018 and will move into a new 38,000 ft2 Animal and Dairy Sciences Building in June of 2019. The Department offers Bachelors of Science degrees with concentrations in Pre-Vet Science/Science, Animal Production, and Business and Industry. Both M.S. and Ph.D. degrees are offered from within the College of Agriculture and Life Sciences in Animal and Dairy Sciences. Job Description:
The Department of Animal and Dairy Sciences is seeking an Assistant Extension Professor for a 12-month tenure track (60% Extension/40% Research) position to coordinate statewide Sustainable Agriculture Research and Education (SARE) programs as well as develop extension and research programs in small ruminant health, reproduction or management. The Animal and Dairy Sciences Department currently houses approximately 380 undergraduate students, 25 graduate students and 22 faculty, both on campus and at research and extension centers throughout Mississippi. The Department conducts teaching, research and extension activities on the 1200 acre south farm that includes a research sheep herd.

Extensive Dual Purpose Goat Production System in the Municipality of Capitanejo, Santander, Colombia6/26/2019 ![]() Abstract The Chicamocha Medio is an ecoregion where the goat culture is considered an important economic activity for the peasant families. Therefore, it was proposed to identify goat management practices to generate specific information that is useful for institutions in different scenarios. A non-probabilistic sample was taken from 33 goat production units from nine municipalities of this region. The diagnosis was made through a semi-structured survey on: 1. plots classification, 2. technical support, 3. livestock inventory, 4. goat facilities, 5. productive aim, 6. herd management, 7. sanitary plan, 8. type of productive system and food and 9. biosafety. It was established that the goat culture is developed in smallholdings with an average inventory of 59 heads, with adapted infrastructure and low technological inclusion. The predominant productive purpose is meat, its management is traditional in a semi-confined system and the main health problem referred to is gastrointestinal parasitism. It is concluded that the management of the flock is traditional with low technological inclusion, the sanitary problems are of infectious origin and the solutions offered to this productive line are very incipient.

The Cultural Landscape: An Oral Study Through the Testimony of Volcano Mauro Carrillo, Colombia6/25/2019 ![]() Abstract This article was raised to provide a description of the technical and economic parameters given in the extensive dual purpose goat production in the region of the Chicamocha Medio. The methodology was descriptive with quantitative variables and convenience sampling, the information was collected by observation and semi-structured surveys of direct application, and then it was validated through the producer panel technique. The ignorance of these parameters limits the efficacy in the decision-making of the producers, directly affecting the development of the chain, evidencing in the existing shortcomings in the administrative and market management.

La Guajira es el departamento con mayor población ovinocaprina de Colombia, los animales han permanecido desde la época de la conquista en poder de las comunidades indígenas Wayúu, asentadas en la media y alta Guajira. Los sistemas de producción, la crianza y manejo de estos animales se adecúan a el ecosistema en el que viven y a la cultura de la etnia Wayúu, siendo para los occidentales una alternativa que ayuda a preservar de manera eficiente los recursos naturales. El Ministerio de Agricultura y Desarrollo Rural de Colombia y Agrosavia, investigan sobre la medicina tradicional y la proyección de estos sistemas a mercados internacionales. Un agradecimiento especial a Clara Viviana Rúa Bustamante (IGA-CR, Colombia) por esta información. "At the recently held Animal Production Society of Kenya's Scientific conference in Nakuru, there was a meeting of farmers who are members of the Dairy Goat Association of Kenya (DGAK), along with researchers and experts in animal production. They observed that shrinking land sizes and increased urbanisation are some of the things that are taking a toll on goat farming."
