Variabilidade Genética do Peso Adulto de Matrizes em um Rebanho Nelore do Estado de São Paulo
(2000-11-01)
Records of 776 Nellore cows from a herd raised at São Paulo State, Brazil, were analyzed to determine the cow mature weight and to estimate their genetic and phenotypic parameters. A previous analysis showed that month and ...
Genetic correlations between mature cow weight and productive and reproductive traits in Nellore cattle
(2012-12-01)
We investigated genetic associations between mature cow weight (MW) and weaning weight (WW), yearling weight (YW), weight gain from birth to weaning (GBW), weight gain from weaning to yearling (GWY), weaning hip height ...
Effects of inorganic copper injection in beef cows at late gestation on fetal and postnatal growth, hematology and immune function of their progeny
(Elsevier, 2021-10)
To determine if Cu injection during late gestation can affect fetal and postnatal growth, hematology and immune function of progeny, 70 multiparous pregnant Angus cows, at 219 ± 15 d of gestation, were ranked by BW and BCS ...

Cow and herd predictors of udder health status in a random sample of argentinian dairy herds
(Universidad de Buenos Aires. Facultad de Ciencias Veterinarias, 2017-11)
The objective of this observational study was to evaluate the relationship between cow- and herd-level factors and cow udder health status, measured by composite milk sample somatic cell count (CSCC) in dairy herds from ...
Correlações genéticas de características de tamanho corporal e condição corporal com características de eficiência produtiva de fêmeas da raça Canchim
(2008-03-01)
The objectives of this study were to obtain heritability estimates for number (NBZ10 and NBZT) and kilograms (QBD10 and QBDT) of calves weaned up to ten years of age and during herd life, kilograms of calves weaned per ...

Evidence for Involvement of IL-9 and IL-22 in Cows' Milk Allergy in Infants
(Mdpi Ag, 2017)
Although allergic inflammation is characterized by a T helper (Th) 2-dominant immune response, the discovery of a role for new T cell subsets in inflammatory diseases has added an additional layer of complexity to the ...
