To achieve this, 20 calves of primiparous and 20 calves of multiparous cows were selected. The calves were monitored for 30 days and scored for signs of disease, as described in McQuirk (2008); according to score, they were divided into healthier calves; the Low calf score group (LCS, 5\u20138), Medium calf score group (MCS, 9\u201312) and High calf score group (HCS, 14\u201317); or calves most prone to disease. Their mothers were monitored for the same period with a Lely Astronaut 3 herd management system (Lely, Maassluis, The Netherlands) for rumination time, milk yield, milk fat, protein, lactose concentrations and milk fat to protein ratio. Both cows and calves were sampled for blood, and concentrations of glucose with \u03b2-hydroxybutyrate were registered. The results indicate that primiparous cows had a 16% higher blood glucose concentration (3.03 mmol\/L SE = 0.093) compared with multiparous cows (2.61 mmol\/L, SE = 0.102) (p &lt; 0.01), but no difference in calf glucose was recorded. \u0392-hydroxybutyrate levels did not differ significantly between cows and calves by parity group. Rumination time was longest in the HCS group at 550.79 min\/d. and was 16% longer compared with the LCS group (461.94 min\/d.; p &lt; 0.001) and 8% longer compared with the MCS group (505.56 min\/d.; p &lt; 0.001). The MCS group rumination time mean was statistically significantly higher compared with the LCS group by 8% (p &lt; 0.001). Milk yield was also highest in the HCS group (44.8 kg\/d.): 19% higher compared with the MCS group (36.31 kg\/d., p &lt; 0.001) and 13% higher than the LCS group (38.83 kg\/d., p &lt; 0.001). There was also a significant difference between the MCS and LCS groups of 6% (p &lt; 0.001). The HCS group had the highest milk fat concentration (4.47%): it was 4% higher compared with the LCS group (4.28%, p &lt; 0.001) and 5% higher than the MCS group (4.25%, p &lt; 0.001). Milk fat to protein ratio was highest in the HCS group (1.21) and was 7% higher than in the MCS group (1.12, p &lt; 0.001) and 8% higher than in the LCS group (1.11, p &lt; 0.001). The LCS group was determined to have the highest concentration of milk lactose (4.66%). It was 1% higher compared with the MCS group (4.62%, p &lt; 0.001) and 1.07% higher than the HCS group (4.61%, p &lt; 0.001). We can conclude that parity did not affect calf health status and that cows of the HCS group showed symptoms of negative energy balance expressed through higher milk yield, higher milk fat concentration and higher milk fat to protein ratio, with lower milk lactose concentration. Further and more thorough research is needed to evaluate the relationship between pregnant cows and calves.<\/jats:p>","DOI":"10.3390\/ani13162576","type":"journal-article","created":{"date-parts":[[2023,8,10]],"date-time":"2023-08-10T10:24:47Z","timestamp":1691663087000},"page":"2576","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Evaluation of the Metabolic Relationship between Cows and Calves by Monitoring Calf Health and Cow Automatic Milking System and Metabolic Parameters"],"prefix":"10.3390","volume":"13","author":[{"given":"Mingaudas","family":"Urbutis","sequence":"first","affiliation":[{"name":"Large Animal Clinic, Veterinary Academy, Lithuanian University of Health Sciences, LT-47181 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dovil\u0117","family":"Mala\u0161auskien\u0117","sequence":"additional","affiliation":[{"name":"Large Animal Clinic, Veterinary Academy, Lithuanian University of Health Sciences, LT-47181 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8572-2616","authenticated-orcid":false,"given":"Mindaugas","family":"Televi\u010dius","sequence":"additional","affiliation":[{"name":"Large Animal Clinic, Veterinary Academy, Lithuanian University of Health Sciences, LT-47181 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9777-8243","authenticated-orcid":false,"given":"Vida","family":"Juozaitien\u0117","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Natural Sciences, Vytautas Magnus University, LT-44248 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7366-7242","authenticated-orcid":false,"given":"Walter","family":"Baumgartner","sequence":"additional","affiliation":[{"name":"University Clinic for Ruminants, University of Veterinary Medicine, A-1210 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9993-2224","authenticated-orcid":false,"given":"Ram\u016bnas","family":"Antanaitis","sequence":"additional","affiliation":[{"name":"Large Animal Clinic, Veterinary Academy, Lithuanian University of Health Sciences, LT-47181 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Immler, M., B\u00fcttner, K., G\u00e4rtner, T., Wehrend, A., and Donat, K.
