(Universidad de Chile, 2005)Los objetivos de este trabajo fueron describir histológicamente el ovario de Fissurella crassa, caracterizando los diversos estados de madurez gonadal de esta especie; detectar la presencia de progesterona en la gónada ...
-
(Sociedad Chilena de Anatomía, 2016)The laboratory rat (Rattus norvegicus albinus) laboratory rat has long been used as a biological model for research. Therefore knowledge of its anatomy, particularly as related to pulmonary lobulation is useful for any ...
-
(1996)The specific lacrimal fluid IgA levels and the specific serum IgG levels of broiler chicks (meat type hybrids (MT)), brown-egg layer chicks (heavy layer (HL)), and white leghorn chicks (light layer (LL)) were compared after ...
-
(Elsevier, 2014)The biological control service supplied to croplands is a result of the predator community present within a focal crop, which is likely influenced by surrounding landscape composition and configuration. In this study, ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2003-09)The avian eggshell is an acellular bioceramic containing organic and inorganic phases that are sequentially assembled during the time the egg moves along the oviduct. As it has been demonstrated in other mineralized tissues, ...
-
(MDPI, 2021)Even though behavioural and physiological reactions to predation risk exhibited by prey species have received considerable attention in scientific journals, there are still many questions still unsolved. Our aim was to ...
-
(MDPI, 2021)Research is ongoing to find nutritional methane (CH4 ) mitigation strategies with persistent effects that can be applied to grazing ruminants. Lipid addition to dairy cow diets has shown potential as means to decrease ...
-
(Frontiers Media, 2022)Salmonella spp. is a relevant foodborne pathogen with worldwide distribution. To mitigate Salmonella infections, bacteriophages represent an alternative to antimicrobials and chemicals in food animals and food in general. ...

-
(Taylor and Francis, 2014)In Africa, the genus Xenopus presents cryptic species and diverse hybrids between species. It has been assumed that the invasive populations of this genus correspond to X. laevis and that they are derived from the subspecies ...
-
(BMC, 2022)Background Porcine circovirus type 2 (PCV2)-associated diseases are a major problem for the swine industry worldwide. In addition to vaccines, the availability of antiviral polymers provides an efficient and safe option ...

-
(2014)La elevada prevalencia de ciertas infecciones en los animales y su impacto económico a nivel productivo y en salud pública, han orientado los esfuerzos hacia la búsqueda de nuevos métodos de control y prevención, alternativos ...
-
(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 ...
