Graphical AbstractAbstract.The research was carried outs in the province of Pastaza in the Ecuadorian Amazon with the objective of determining external and internal quality at different days of storage in Creole eggs sent to local markets. 840 Creole eggs were evaluated, which were measured depending on the days of storage, and 120 eggs were sampled MOL2NET, 2019, 5, doi:10.3390/mol2net-05-xxxx 2 for each day of storage. The treatments to be applied were seven storage times 0, 5, 10, 15, 20, 25 and 30 days. The variables that were measured for external quality were egg weight, shape index and shell index. For internal quality was evaluated: yolk index and haugh Units. A Fully Randomized Design (DCA) was used. The external quality of the egg is affected only by the weight, which decreases after 10 days of storage in local markets, while the shape index and the shell index did not show any alteration. Regarding internal quality, the indicators of the yolk index and Haugh Units began to decrease their quality as the days of storage increased, affecting the commercialization process. It is considered that for the commercialization and packaging the Creole egg can be used until day 5 taking into account the yolk index, whereas with respect to Haugh Units until day 25 of storage in local markets for the conditions of the Ecuadorian AmazonInsert abstract text here

The objective of the study was to evaluate the main causes that affect the low productivity and quality of the primary link of the cattle production chain as an input for the food transformation industry and related to other destinations in the Ecuadorian Amazon region (RAE). Questionnaire were conducted with 399 variables from each of the Amazonian provinces to evaluate behavior in the productive, environmental, economic and social dimensions of livestock systems and animal behavior of the different breeds. The results were analyzed once the livestock systems were typified in each productive purpose, we analyzed the discrete variables that affect the behavior of the systems, related to the productive dimensions (individual milk production and birth rate) and ANAVA for breeding breeds more frequent in each of the provinces. The composition of the systems in the RAE showed that the most frequent breeds are Criollo (35.9) and mestizos without records (63.3%) with a specialized breed deficit that means that the agroindustrial sector is almost non-existent. The Norman races; Holstein and Brown Swiss present births of 82.47; 78.19 and 66.47% respectively, however they do not express their milk production potential due to the management system used. It is concluded that the link that presents the greatest vulnerability is the primary one (livestock farmers) mainly because in the RAE are producing with important productive deficiencies.

El objetivo de este trabajo fue realizar estudios básicos sobre: las bases fenotípica y genotípica intrarracial del bovino Macabeo como recurso genético endémico en peligro de extinción en la amazonia ecuatoriana; estudios de bioquímica sanguínea y; la caracterización de los sistemas productivos donde estos hatos se han desarrollado. Los principales resultados mostraron biotipos de poblaciones con alta variabilidad fenotípica con respecto al color de la piel, pero con gran similitud en la distribución de la pigmentación de la franja lineal longitudinal en el cuerpo, en correspondencia con la coloración de cabeza y extremidades; con cuernos grandes y abiertos. El acercamiento genético fue con la raza ibérica el Hartón del Valle de Colombia, lo que indica que tienen un origen común o se han producido migraciones de individuos de estas razas; existe en el hato una elevada consanguinidad de (0.089±0.12). Entre las principales alteraciones bioquímicas sanguíneas, sobresalen los porcentajes de subnormalidad de los niveles de proteína (65,24 g/l), urea (2,08 mmol/l) y glucosa (1,97 mmol/l), todo ello se relaciona con la nutrición proteica y energética. El ganado bovino Macabeo tiene alto potencial genético, por su adaptación al trópico, por lo que se recomienda considerarlos para perfeccionar en el país el programa de conservación y mejora de este genotipo.
