Heritability (0.08) was evaluated in a model whereas the comparable group used interaction between herd and control day. The influence of as heritability (0.03). herds years testing (0.04 0.05). Phenotypic correlations milk urea concentration milking traits: daily quantity milk, content fat proteins (P <0.0001). Positive low phenotypic correlation (0.15) found yield, amount (0.10).

Estimates of Genetic and Phenotypic Parameters for Milk Production in Moroccan Holstein-Friesian Cows
To satisfy the growing demand of the human population for milk, the Moroccan government set up a plan in 1975 to increase milk production. The most important genetic strategies were the introduction of improved dairy cattle, the institution of milk recording, and the extension of artificial insemination (AI). Thus, more than 10,000 Holstein and Friesian heifers were purchased annually from Euro...
متن کاملGenetic and Phenotypic Parameters for Milk Production Traits in the First and Second Lactation in Romanian Simmental Dairy Cows
The aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of Romanian Simmental dairy cattle. For the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...
متن کاملEstimation of Genetic Parameters for Milk Production Trait in Holstein Cows of the Mazandaran Gavdasht Herd Using Test Day Records
Random regression models (RRM) are used for genetic estimations of milk traits in dairy cows. RRM utilize data on traits that are repeated during the time, such as milk trait, which allows of the evaluation of the test day production information. In this study, to estimate genetic parameters for milk production trait, test day records (TDR) were collected from the first lactation of Holstein co...

Genetic relationship between milk urea nitrogen and reproductive performance in Holstein dairy cows.
The objective of this study was to describe the genetic and phenotypic relationship between milk urea nitrogen (MUN) and reproductive traits in Iranian Holstein dairy cows. Test-day MUN data obtained from 57 301 dairy cows on 20 large dairy herds in Iran between January 2005 and June 2009. Genetic parameters for MUN and reproductive traits were estimated with a five-trait model using ASREML pro...
