Abstract
Dairy cattle on organic farms are still selected on the basis of information from conventional systems. Productivity of cows differs between organic and conventional herds, therefore, the ability of cows to adapt to an organic production environment has been questioned. The aim of this study was to investigate the milk yield and milk ability traits during lactation of Lithuanian black & white and Holstein cows with different genotypes in organic farm. The research was carried out in organic farm in 2020 with dairy cows (n=364) of different genotype of Lithuanian black and white cattle population. The milk yield (MY), milking speed (MS), highest milk flow (HMF), milking time (MT) were evaluated. Investigated traits were measured with DeLaval electronic milk meters, “Apro Windows” software. All records were between five and 305 days of lactation. The statistical analysis of data was performed using the SPSS 20.0 (SPSS Inc., Chicago, IL, USA) software package. A probability of less than 0.05 was considered significant (P<0.05). We observed that a highest MY and HMF in organic farm was detected in cows with a genotype of Lithuanian Black and White breed (LB&W, LB&WxH and LB&WxHxLB&W) during all stages of lactation. MT of these cows during the first two stages of lactation was longer, compared to cows of other genotypes. We estimated that of all fixed effects the biggest influence on MY, MS, MT was by stage of lactation (P<0.001); a genotype showed a highest impact on MT(P<0.001) and MY(P<0.01).
