The aim of this research was to define methods for early prediction (based on 1. milk control record) of lactation flow in Holstein heifers as well as to choose optimal one in terms of prediciton fit and application simplicity. Total of 304,569 daily yield records automatically recorded on a 1,136 f ...

Oznake: cattle;breeds;Slovenian Holstein;longevity;Weinbull proportional hazards model;
The longevity of Slovenian Holstein population was analzsed using survival analysis with a Weibull proportional hazard model. Data spanned the period between January 1991 and January 2010 for 116,200 cows from 3,891 herds. Longevity was described as the length of productive life - from first calving ...

Izvirni znanstveni članek
Oznake: govedo;krave;molznice;starost;mastitis;mlečnost;
The purpose of this study is to determine the effect of age of cows on variability in mastitis prevalence risk and its concomitant impacts on their successive daily milk yield by analyzing test-day records of dairy cows collected in the period 2005–2022. The results obtained indicate a correlation b ...

Oznake: cattle;Holstein;milk traits;heritability;correlations;genetic trends;Slovenia;Croatia;
The objective of this study was to estimate genetic parameters for milk traits (daily milk, fat, and protein yield) for a joint genetic evaluation in Holstein breed in Croatia and Slovenia and to compare results from the joint and national evaluation systems. Test-day records from Croatian (CRO) and ...
