Effect of test year, parity number and days in milk on somatic cell count in dairy cows of Los Rios region in Chile
(Universidad Austral de Chile, Facultad de Ciencias Veterinarias, 2020)
In Chile, most dairy cattle are located in the southern region of the country, where the largest volume of milk is produced. This study aimed to quantify changes of somatic cell count (SCC) over 20 years in 11 herds of the ...

Genetic parameters for buffalo milk yield and milk quality traits using Bayesian inference
(Amer Dairy Science Assoc-adsa, 2010-05-01)
The availability of accurate genetic parameters for important economic traits in milking buffaloes is critical for implementation of a genetic evaluation program. In the present study, heritabilities and genetic correlations ...

Effect of residual variance heterocedasticity on milk yield and age at first calving genetic parameter estimates
(2010-01-01)
Genetic evaluation programs assumed homocedasticity of residual variance estimates for different milk yield levels. The objective of this study was to estimate genetic parameters for 305-d milk yield (MY305) and age at ...
Genetic parameters for test-day milk yield, 305-day milk yield, and lactation length in Guzerat cows
(2013-04-01)
Milk production in tropical environments requires the use of crossbreeding systems including breeds well adapted to harsh conditions, but with lower productivities when compared to specialized breeds. Besides the genetic ...

The effect of a product with three gluconeogenic precursors during the transition period on blood metabolites and milk yield in Chilean Holstein cattle
(Taylor and Francis Ltd., 2018)
The objective of this study was to determine the effect of a product containing calcium propionate 70 g/kg, propylene glycol 95 g/kg and glycerol 330 g/kg on blood β-hydroxy butyrate, non-esterified fatty acids and milk ...
Genetic parameters for milk yield of Bubalus bubalis using unadjusted and adjusted milk production for days in milk
(2007-12-01)
The objectives of this study were to estimate genetic parameters for unadjusted and adjusted milk production for 270 and 305 days of lactation and, subsequently, to verify the coincidence of rank of 2%, 5%, 20% and 40% ...
