Phenotypic plasticity of composite beef cattle performance using reaction norms model with unknown covariate
The objective of the present study was to determine the presence of genotype by environment interaction (G × E) and to characterize the phenotypic plasticity of birth weight (BW), weaning weight (WW), postweaning weight ...
Genotype x environment interaction for age at first calving in Brazilian and Colombian Holsteins
The objective was to determine whether there is a genotype x environment interaction for age at first calving (AFC) in Holstein cattle in Brazil and Colombia. Data included 51,239 and 25,569 first-lactation records from ...

Repeatability and heritability of response to superovulation in Holstein cows
The objective of this study was to estimate the relative effects of genetic and phenotypic factors on the efficacy and efficiency of superovulation for Holstein-Friesian cows reared in Brazil. A database, established by ...
A place preference test in the fish Nile tilapia
The Nile tilapia fish (Oreochromis niloticus) has a high potential to be used as a model in neuroscience studies. In the present study, the preference of the Nile tilapia between a gravel-enriched (GEE), a shelter-enriched ...
Integrated pest management programme in hospital environment
(Sage Publications Ltd, 2015-05-01)
Urban pests are known to infest health service facilities, especially in a warm, wet neotropical climate. In practice, pest control services for health service facilities are generally outsourced and in most cases are not ...
Factors that cause genotype by environment interaction and use of a multiple-trait herd-cluster model for milk yield of Holstein cattle from Brazil and Colombia
Descriptive herd variables (DVHE) were used to explain genotype by environment interactions (G x E) for milk yield (MY) in Brazilian and Colombian production environments and to develop a herd-cluster model to estimate ...
Typing clinical and animal environment Aspergillus fumigatus gliotoxin producer strains isolated from Brazil by PCR-RFLP markers
Aspergillus fumigatus, a well-known human and animal pathogen causing aspergillosis, has been historically identified by morphological and microscopic features. However, recent studies have shown that species identification ...
Animation modeling with Petri Nets

Performance of laying hens and economic viability of different climatization systems
Since thermal environment affects production, egg quality and laying hens' mortality rates, it is highly relevant to control the thermal environment within poultry houses so that the best financial profits could be obtained. ...
