Beef production from dairy bulls under two different production systems and its effect on the fatty acid profile and beef quality.
(CIENCIAS, 2014)Bulls in dairy production are usually slaughtered at an early age to avoid production problems and unnecessary costs. However, the animals could be a source of additional income and better quality meat. The objective of ... -
Effects of pregrazing herbage mass in late spring on enteric methane emissions, dry matter intake, and milk production of dairy cows
(CIENCIAS, 2016)Few studies have examined the effects of fresh forage quality on enteric methane (CH4) emissions of dairy cows under grazing conditions. The aim of the current study was to evaluate the effects of 2 contrasting forage ... -
Evaluation of chañar seed cake from biodiesel production as a soil amendment.
(CIENCIAS, 2014)One of the major problems for biodiesel producers is the disposal of the seed cake after expelling oil from seeds. Every ton of biodiesel results in 2.5 to 3 tons of seed cake as byproduct. The physicochemical characteristics ... -

(Facultad de Ciencias, 2013)Flavobacterium columnare, a fastidious Gram-negative pathogen and the causative agent of columnaris disease, is one of the most harmful pathogens in the freshwater fish-farming industry. Nevertheless the virulence mechanisms ... -
Insect abundance and damage on the deciduous Nothofagus macrocarpa increase with altitude at a site in the Mediterranean climate zone of Chile
(CIENCIAS, 2015)An understanding of the spatial and temporal patterns of insect abundance and plant damage across altitudinal gradients and the mechanisms driving them is limited. Importantly, little is known in this area in relation to ... -
Interspecific recognition in Chilean parabiotic ant species
(CIENCIAS, 2003)In Chile, Camponotus morosus and Solenopsis gayi sometimes co-inhabit a single nest, seemingly in a parabiotic association. To elucidate the nature of this association we conducted behavioural tests that measured aggression ... -
