Genetic analysis of clinical mastitis data for Holstein cattle in the Czech Republic

Peters (1927) descreveu que, atraídos pelo odor característico do ácido acético, insetos dípteros, conhecidos por moscas do vinagre (Drosophila funebris) transportam o nematóide para

Indirect genetic selection for udder depth, bone quality, udder height, rear teat placement and conforma- tion traits showed the highest genetic correlations with measurements of

In animal breeding, these models are used to infer genetic parameters such as heritability and genetic correlations, linear combinations of fixed effects ( e.g ., diferences in

The objective of this study was to estimate the covariance components and genetic parameters for test- day milk, fat and protein yields of primiparous Holstein cows, using

Data was available on daily average milk yield (AMY), total lactation milk yield (TMY), last milk yield before drying of (LMY) and milk yield corrected for 305 days lactation

Two hundred and seventeen records on milk production per lactation period (MY), milk production up to 305 days of lactation (MY305) and length of lactation period (LL) of 82

Therefore, the aim of this study was to estimate heritability as well as genetic and environmental correlations between 305-day milk yield (Milk305), milk yield in the first

percent (P%), protein yield (PY), somatic cell score (SCS), and total bacterial count score (TBCS) as well as to estimate the genetic correlations among these traits, using a
