Systemic inflammation in early lactation and its relation to the cows' oxidative and metabolic status, productive and reproductive performance, and activity

Autor: M.Q. Zhang, S. Heirbaut, X.P. Jing, B. Stefańska, L. Vandaele, N. De Neve, V. Fievez

Publikováno v: Journal of Dairy Science, Vol 107, Iss 9, Pp 7121-7137 (2024)

ABSTRACT: A dysregulated inflammatory response contributes to the occurrence of disorders in cows during the transition period from pregnancy to lactation. However, a detailed characterization of clinically healthy cows that exhibit an enhanced infla

Autor: M. Salamone, I. Adriaens, A. Liseune, S. Heirbaut, X.P. Jing, V. Fievez, L. Vandaele, G. Opsomer, M. Hostens, B. Aernouts

Publikováno v: Journal of Dairy Science, Vol 107, Iss 1, Pp 304-317 (2024)

ABSTRACT: The transition period is one of the most challenging periods in the lactation cycle of high-yielding dairy cows. It is commonly known to be associated with diminished animal welfare and economic performance of dairy farms. The development o

Combination of milk variables and on-farm data as an improved diagnostic tool for metabolic status evaluation in dairy cattle during the transition period

Autor: S. Heirbaut, X.P. Jing, B. Stefańska, E. Pruszyńska-Oszmałek, B. Ampe, C. Umstätter, L. Vandaele, V. Fievez

Publikováno v: Journal of Dairy Science, Vol 107, Iss 1, Pp 476-494 (2024)

ABSTRACT: Milk composition, particularly milk fatty acids, has been extensively studied as an indicator of the metabolic status of dairy cows during early lactation. In addition to milk biomarkers, on-farm sensor data also hold potential in providing

Publikováno v: Journal of Dairy Science, Vol 106, Iss 8, Pp 5723-5739 (2023)

ABSTRACT: Metabolic and oxidative stress have been characterized as risk factors during the transition period from pregnancy to lactation. Although mutual relations between both types of stress have been suggested, they rarely have been studied conco

Prediction of metabolic status of dairy cows in early lactation using milk fatty acids and test-day variables

Autor: Muluken Girma, A.T.M. van Knegsel, S. Heirbaut, L. Vandaele, X.P. Jing, B. Stefańska, V. Fievez

Publikováno v: Journal of Dairy Science, Vol 106, Iss 6, Pp 4275-4290 (2023)

ABSTRACT: Early lactation metabolic imbalance is an important physiological change affecting the health, production, and reproduction of dairy cows. The aims of this study were (1) to evaluate the potential of test-day (TD) variables with or without

Diagnostic milk biomarkers for predicting the metabolic health status of dairy cattle during early lactation

Autor: S. Heirbaut, X.P. Jing, B. Stefańska, E. Pruszyńska-Oszmałek, L. Buysse, P. Lutakome, M.Q. Zhang, M. Thys, L. Vandaele, V. Fievez

Publikováno v: Journal of Dairy Science, Vol 106, Iss 1, Pp 690-702 (2023)

ABSTRACT: Data on metabolic profiles of blood sampled at d 3, 6, 9, and 21 in lactation from 117 lactations (99 cows) were used for unsupervised k-means clustering. Blood metabolic parameters included β-hydroxybutyrate (BHB), nonesterified fatty aci

Different reticuloruminal pH metrics of high-yielding dairy cattle during the transition period in relation to metabolic health, activity, and feed intake

Autor: S. Heirbaut, D. Børge Jensen, X.P. Jing, B. Stefańska, P. Lutakome, L. Vandaele, V. Fievez

Publikováno v: Journal of Dairy Science, Vol 105, Iss 8, Pp 6880-6894 (2022)

ABSTRACT: The measurement of pH in the reticulorumen in combination with a time–pH threshold has been widely applied in research to diagnose subacute ruminal acidosis. However, other pH metrics also have biological value. In this study, 44 animals

Subacute ruminal acidosis phenotypes in periparturient dairy cows differ in ruminal and salivary bacteria and in the in vitro fermentative activity of their ruminal microbiota

Autor: H. Yang, S. Heirbaut, J. Jeyanathan, X.P. Jing, N. De Neve, L. Vandaele, V. Fievez

Publikováno v: Journal of Dairy Science, Vol 105, Iss 5, Pp 3969-3987 (2022)

ABSTRACT: Both ruminal microbial structure and functionality might play a role in inter-individual variation in susceptibility for subacute rumen acidosis (SARA) observed in dairy cows. The aims of this study were to determine whether differences bet
