Development of facial masks for indirect calorimetric studies for livestock
With the use of a facial mask, it is possible to evaluate the gaseous exchange of an animal outdoors. But the question is: can an animal put on a facial mask for a long period of time without affecting its physiological ...
Serological survey of Toxoplasma gondii in captive Neotropical felids from Southern Brazil
Toxoplasma gondii is the causative intracellular protozoan of toxoplasmosis in human being and animals. Members of the Felidae family are considered the single definitive host for the infection; both wild and domestic cats ...
Thermal ecology of small animals
One of the most representative cases in which the relation individual-environment is evident is the heat exchange between animals and their physical environment. Based on the physical laws regulating heat exchange and on ...
Two-Way Selection for Daily Gain and Feed Conversion in a Composite Rabbit Population
We conducted a two-way selection experiment in a composite rabbit population to investigate the responses to selection for postweaning ADG and feed conversion (FC). Two generations of crossing, followed by four generations ...
Efeito da tosquia na temperatura corpórea e outros parâmetros clínicos em ovinos
The aim of this study was to determine the variation of the temperature after shearing in sheep under dry and hot environment conditions and to compare the temperature changes with variation in cardiac and respiratory ...

Influence of hot environments on some blood variables of sheep
Thirty-two Polwarth sheep of ages up to 1 year were observed under temperatures varying from 10.5 to 46.5°C. The following blood cell counts were made: erythrocyte (RBC), leucocyte (WBC), eosinophil (EOS), neutrophil (NEU), ...
Genotype-environment interaction for post-weaning traits in Nellore beef cattle
(CSIRO Publishing, 2012-01-01)
Identification of genotype-environment interaction in beef cattle may help the artificial selection process and increase the efficiency of genetic evaluation on sires submitted to different environments. Post-weaning traits ...
