The relationship between feed efficiency and behaviour differs between lactating Holstein and Jersey cows Open
In dairy production, high feed efficiency (FE) is important to reduce feed costs and negative impacts of milk production on the climate and environment, yet little is known about the relationship between FE, eating behaviour and activity. …

Behavioural tests Open
To answer specific questions regarding cow behaviour or affective states, it is sometimes necessary to study the cow’s responses to specific stimuli in a test situation. This can be done either in the animal’s home environment or in a test…

Lying, standing, and eating behaviour Open
Standing and lying behaviours are well-defined. Lying is often described as when the flank or sternum of the animal is in contact with the ground, and end of lying when all four legs are perpendicular to the body (see [1]). The transition …

Feed and water intake Open
Knowledge about dry matter intake (DMI) is a very important element in cattle management. Modern, high producing dairy cows require great amount of feed in order to meet the nutrient and energy requirements for maintenance and milk product…

Technical note: Random forests prediction of daily eating time of dairy cows from 3-dimensional accelerometer and radiofrequency identification Open
Feed intake and time spent eating at the feed bunk are important predictors of dairy cows' productivity and animal welfare, and deviations from normal eating behavior may indicate subclinical or clinical disease. In the current study, we d…

Changes to steps, lying, and eating behavior during lactation in Jersey and Holstein cows and the relationship to feed intake, yield, and weight Open
Devices that record behavior automatically have made it possible to accurately measure the lying and eating behavior of large numbers of dairy cows. During lactation, weight, feed intake, and production of cows change; however, longitudina…

Rumination activity Open
The daily rumination pattern in cattle is influenced by different factors such as feeding frequency, physical and chemical characteristics of the diet, feeding time, fasting, photoperiod and grazing management [1], [2], [3], [4], [5]. Stud…

The effect of transition cow housing on lying and feeding behavior in Holstein dairy cows Open
The present study investigated the effect of straw yard housing during the dry period and 2 d of additional maternity pen housing postcalving on lying and feeding behavior and calving difficulty in Holstein dairy cows. In this study, 122 m…
