The effect of climate on dairy and beef cattle is variable and complex because it affects the environment in which the animals are raised and reproduced. Its influence on animal welfare and production have been recognized and studied since 1950's. Climate affects livestock directly and indirectly...

El efecto del clima en el ganado bovino es variable y complejo, ya que condiciona el medioambiente en el que los animales viven y se reproducen. Sus influencias en el bienestar y producción animal han sido reconocidas y estudiadas desde 1950. El clima afecta al ganado directa e indirectamente, ya...

Datos climáticos del periodo diciembre a febrero de los años 1999 al 2007 provenientes de estaciones meteorológicas situadas en Curicó, Chillán, Temuco y Osorno fueron utilizados para calcular un índice temperatura-humedad ajustado por el efecto del viento y de la radiación (THIadj-max). Las vari...

Meteorological data from December to January of years 1999 to 2007 from weather stations located in four localities in Chile (Curicó, Chillán, Temuco and Osorno) were used to calculate the adjusted temperature-humidity index (THIadj-max). Climate variables used to calculate the index were: wind s...

Se evaluó el efecto del tipo de sustrato a fermentar por Saccharomyces cerevisiae (Sc) sobre la digestibilidad in vitro de la proteína cruda (Divcp y Div2h), de la proteína verdadera (Dtp) y la tasa de degradación de proteína (kdcp) en diferentes extractos proteicos producidos por esta levadura. ...

The in vitro crude protein (CP) digestibility (Divcp), true protein digestibility (Dtp) and degradation rate (kdcp) were measured in different protein extracts of Saccharomyces cerevisiae (Sc) yeast. These extracts were generated through a biotechnological method (solid state fermentation). Wheat...

The high content of crude protein (CP) of pastures in southern Chile creates a nutritional imbalance that results in large amount of nitrogen (N) being excreted into the environment. Two regression equations and a dynamic model, available from the literature, were utilized to simulate the N use e...

The objective of the study was to assess the effects of summer weather conditions on animal performance and behaviour in southern Chile. Data of milk yield, animal activity, tympanic temperatures (TT; n = 15), and three comfort thermal indices were collected in La Araucania Disctrict. Time of day...

A summer study and a winter study were conducted using an incomplete factorial structure in a complete randomized design. Within season, the factors studied were 1) type of diet, which included 2 levels of ME, classified as either concentrate (3.04 Mcal of ME/kg) or roughage (2.63 Mcal of ME/kg) ...
