Estimativa da mudança genética na produção de leite e gordura em bovinos da raça Holandesa
(1997-07-01)
The objective of this study was to estimate the genetic trends of the milk and fat yield in three herds maintained in São Paulo State, Brazil. The estimation of genetic, environmental and phenotypic trends were based on ...
Adherence and experimental infection of bacteria associated with periodontal infections of young cattle in Brazil (Cara inchada)
(1997-07-01)
In vitro- and in vivo-assays were conducted, to study the possible role of streptomycin-and actinomycin-producing soil actinomycetes for the pathogenesis of Cara inchada in cattle (CI). Adherence of Bacteroides spp. to ...

Consistency of side choice in the milking parlour by holstein-friesian cows and its relationship with their reactivity and milk yield
(2001-02-19)
Dairy cows often have to choose which of two sides to enter in the milking parlour. Some cows are very consistent in this choicė, and it is common to assume that when these cows are more disturbed are being milked in their ...

Repeatability and heritability of response to superovulation in Holstein cows
(1999-04-15)
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 ...
