Screening of Polish Holstein-Friesian bulls towards eradication of complex vertebral malformation (CVM) carriers.
The effectiveness of a program aimed at eradicating carriers of the recessive disorder Complex Vertebral Malformation (CVM) from the population of Holstein-Friesian bulls is reported. Among 1823 bulls, 1268 young and 555 proven bulls were examined. Three hundred and three bulls appeared to be CVM carriers (16.62%). The highest number of carriers occurred in the sons of a CVM sire, 55.51% and 61...

متن کاملGenetic analysis of lactation persistency in the Polish Holstein-Friesian cows*
The objectives of this study were to analyze the genetic properties of three measures of lactation persistency in Polish Holstein-Friesian cows, and possibly to choose one measure which could be used for estimation of breeding value for lactation persistency in the Polish dairy cattle population. Data included 117,327 first three lactations of 110,141 cows calved in 1995-2009. The lactation cur...
متن کاملThe effect of non-genetic factors on reproduction traits of primiparous Polish Holstein-Friesian cows
The aim of this research was to estimate the influence of environmental factors, such as air temperature and milk production, on reproduction traits of primiparous Polish Holstein-Friesian cows. The following reproduction traits were considered: interval from calving to first insemination, interval from first to last insemination, interval from calving to conception, number of inseminations per...
