The influence of pregnancy on production traits in dairy cattle

Original language description

The aim of this study was to evaluate the effects of pregnancy in cows on milk production measured as kg and content of milk components. The comparison was made between pregnant and non-pregnant twins created from multiple births. The monitored twins, born between years 2000?2006 (n = 97), had the same father and mother, the first calving occurred at the same farm and in the same time period (?1 month). The aim was to create cow pairs, comparable in terms of genetic and environmental factors at first lactation. The first group included cows which became pregnant 60 days after calving. The second group was made up of their non pregnant twin-equals. The results showed differences in milk production. Measured traits were daily milk production in kg, fat in % and protein content in kg, and somatic cell count. There was a statistically insignificant decline in milk production in pregnant cows for each time period of pregnancy (1?30; 31?60; 61?90 and 91 to 120 days). This was -0.46; -1.33; -
