Publikováno v: Animal, Vol 16, Iss 3, Pp 100470- (2022)

During early lactation, most dairy cows experience negative energy balance (NEB). Failure to cope with this NEB, however, can place cows at greater risk of developing metabolic disease. Our objective was to characterise, retrospectively, lying behavi

Graduate Student Literature Review: Evaluating the appropriate use of wearable accelerometers in research to monitor lying behaviors of dairy cows

Autor: DJ Donaghy, C.V.C. Phyn, John R Roche, S.J. Hendriks, K.R. Mueller, S. A. Turner, J.M. Huzzey

Publikováno v: Journal of Dairy Science. 103:12140-12157

Until recently, animal behavior has been studied through close and extensive observation of individual animals and has relied on subjective assessments. Wearable technologies that allow the automation of dairy cow behavior recording currently dominat

Associations between lying behavior and activity and hypocalcemia in grazing dairy cows during the transition period

Autor: John R Roche, S.J. Hendriks, K.R. Mueller, C.V.C. Phyn, J.M. Huzzey, DJ Donaghy, S.-A. Turner, B. Kuhn-Sherlock

Publikováno v: Journal of Dairy Science. 103:10530-10546

Hypocalcemia is a common metabolic disorder of transition dairy cows that is considered a gateway disease, increasing the risk of other health disorders and reducing cow performance. Clinical milk fever is associated with long periods of recumbency,

Changes in behavior and fecal cortisol metabolites when dairy cattle are regrouped in pairs versus individually after calving

Autor: P.L. Knickerbocker, K.A. Mazer, J.M. Huzzey, K.L. Kutina

Publikováno v: Journal of dairy science. 103(5)

Regrouping occurs when dairy cows are moved between pens, and this can negatively affect cow behavior and production. Pen changes occur frequently around calving, a time when cows are vulnerable to health problems. Regrouping cows along with a famili

Publikováno v: Animal Production Science. 60:148

Lying behaviour and activity were measured in healthy grazing dairy cows during the transition from late gestation to early lactation (i.e. the transition period). Behaviour data derived from IceTag® or IceQube® (IceRobotics, Edinburgh, Scotland, U

Lying behavior and activity during the transition period of clinically healthy grazing dairy cows

Autor: S. A. Turner, S.J. Hendriks, B. Kuhn-Sherlock, J.M. Huzzey, K. M. Mueller, John R Roche, C.V.C. Phyn, DJ Donaghy

Publikováno v: Journal of dairy science. 102(8)

Lying behavior and activity may provide useful information for the prediction of an imminent calving and the health of transition dairy cows; however, it is important first to understand what constitutes typical lying behavior and activity because th

Changes in feeding, social, and lying behaviors in dairy cows with metritis following treatment with a nonsteroidal anti-inflammatory drug as adjunctive treatment to an antimicrobial

Publikováno v: Journal of dairy science. 101(5)

Dairy cows with metritis display sickness behaviors, and nonsteroidal anti-inflammatory drugs (NSAID) have the potential to reduce these responses. The objective of this study was to investigate changes in feeding, social, and lying behaviors in dair

Behavioral changes before metritis diagnosis in dairy cows

Autor: J. Lomb, J.M. Huzzey, Heather W. Neave, Stephen J. LeBlanc, M.A.G. von Keyserlingk, Daniel M. Weary

Publikováno v: Journal of dairy science. 101(5)

Metritis is common in the days after calving and can reduce milk production and reproductive performance. The aim of this study was to identify changes in feeding and social behavior at the feed bunk, as well as changes in lying behavior before metri
