(Cambridge University Press, 2014)Information available on the role of Mg for growth and cellulose degradation by rumen bacteria is both limited and inconsistent. In this study, the Mg requirements for two strains each of the cellulolytic rumen species ...
-
(1989)Some aspects of the population dynamics of the vicuña Vicugna vicugna were studied using census and field data recorded at the Reserva Nacional Las Vicuñas, I Region, northernmost Chile. Census data and mean values of ...

(Elsevier, 2018-10-01)This study aims to compare results obtained by mate selection accounting for different components in the objective function (OF), including functions related to genetic variability of the future progeny, using Nile ...
-
(Wiley, 2017)An algorithm to perform mate selection in aquaculture breeding using a computational optimization procedure called "differential evolution" (DE) was applied under optimum contribution selection and mate selection scenarios, ...
-
(Elsevier, 2020)Optimum contribution selection (OCS) and mate selection (MS) are alternative strategies to maximize genetic gain under controlled rates of inbreeding. There is evidence in the literature that MS outperforms OCS in controlling ...
-
(Elsevier, 2011)Several cardiovascular diseases (CVD) observed in adulthood have been associated with environmental influences during fetal growth. Here, we show that maternal exposure to cadmium, a ubiquitously distributed heavy metal ...
-
(Elsevier, 2020)Undernourishment is a frequent condition in sheep pregnancies under extensive systems, since most of the pregnancies occur when the prairie has the lowest forage allowance. Underfed sheep pregnancies are associated with ...
-
(MDPI, 2021)The effects of a combined supplementation with herbal antioxidants during pregnancy on reproductive traits and piglet performance (number of live, dead, and mummified newborns and litter weight at birth and individual ...
-
(2012)Twenty-eight Merino Precoce suckling lambs raised under confinement in the Mediterranean semi-humid dryland of Central Chile were studied to evaluate meat quality and major carcass characteristics. Animals were grouped by ...

(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2012)Twenty-eight Merino Precoce suckling lambs raised under confinement in the Mediterranean semi-humid dryland of Central Chile were studied to evaluate meat quality and major carcass characteristics. Animals were grouped by ...
-
(Universidad de Chile, 2012)Trypanosomacruzi es el agente causal de la enfermedad de Chagas, la infección parasitaria más importante deLatinoamérica. Se considera una enfermedad crónica, que causa discapacidad, para la cual no existe tratamientoefectivo. ...
-
(RESILIENCE ALLIANCE, 2005-06)We conducted a factorial simulation experiment to analyze the relative importance of movement pattern, boundary-crossing probability, and mortality in habitat and matrix on population density, and its dependency on habitat ...
-
(Spandidos Publications Ltd., 2017)Cyclooxygenase (COX)-2 expression is positively correlated with malignant features in canine mammary carcinomas. Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit COX activity and may therefore possess anticancer ...
-
(Universidad de Chile, 2013)Las metaloproteinasas (MMPs) son una familia de enzimas proteolíticas capaces de procesar o degradar proteínas de la matriz extracelular. Las MMPs tienen un prodominio, prodominio catalítico, una región bisagra y un dominio ...

(Pontificia Universidad Católica de Chile, Facultad de Agronomía e Ingeniería Forestal, 2010)Permanent and permeable edges, where natural enemies can feed, overwinter or easily cross over, should enhance the early arrival of these predators to crops. We evaluated the abundance and species richness of coccinellids ...
-
(American Dairy Science Association, 2000)We studied effects of breed, dietary fat source, and dietary copper intake as factors known to influence unsaturation of milk fat and its potential for development of spontaneous oxidized flavor in milk. Twelve Holstein ...
-
(Elsevier, 2011)The objective was to evaluate mitochondrial distribution, and its relationship to meiotic development, in canine oocytes during in vitro maturation (IVM) at 48, 72, and 96 h, compared to those that were non-matured or in ...
-
(BioMed Central, 2013)Background: Chagas disease is caused by the protozoan Trypanosoma cruzi, which is transmitted to mammal hosts by triatomine insect vectors. The goal of this study was to model the spatial distribution of triatomine species ...
