Abstract

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 Araucanía District. Time of day and...

AbstractFull Text

A total of 20 crossbreed steers received an electronic device in the tympanic canal to collect tympanic temperatures (TT). Simultaneously, climatic variables including air temperature, wind speed, solar radiation, relative humidity, and rainfall were collected by using a weather station located at...

AbstractFull Text

The study was conducted in Osorno Chile, in order to assess the effect of castration on average daily gain of weaned calves during the backgrounding phase. The study considered a total of 20 weaned calves of a beef biotype whose average live weight was 189.5 kg (±4.3 SEM). Two groups of 10 animals...

Abstract

A mechanistic model (COWPOLL) was used to estimate enteric methane (CH4) emissions from beef production systems in Chile. The results expressed as a proportion of gross energy intake (GEI) were compared with enteric fermentation data reported in the last Chilean greenhouse gases inventory, which...

Abstract

Meteorological data from December to January of the years 1999 to 2007 from weather stations located in 4 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...

Abstract

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...
