Objective: Resting comfort may influence sleep-related lying postures in cattle. This study aimed to investigate the effects of bed cleanliness on tucked (TSP) and extended (ESP) head positions in sleep-related lying postures.
Methods: The study was conducted over two experimental periods.

Sleep plays an important role in cattle production and welfare. Therefore, this study aimed to investigate the development of sleep-like posture (SLP) expression in dairy calves from birth to the first calving as an indicator of their sleep behavior. Fifteen female Holstein calves were subjected.

Methods: Six calves were stroked by a trainer for 6 minutes once daily for 5 days after birth (D1).
Sleep is one of the essential behaviors in mammalian health and welfare. In this study, we focused on how concentrate-rich diets (Conc) can influence the sleep of cattle. We hypothesized that Conc would suppress the daily sleep of cows because of behavioral frustration according to shorter eating and rumination.

Total 85 behavior data (summer 41, autumn 44) were corrected from 12 commercial tie-stall dairy farm in northern Tohoku area. Daily duration, bout frequency, and averaged bout duration of sleep and lying were measured.

Objective: Environmental change is one of the stressful events in livestock production. Change in environment disturbs cow behavior and cows require several days to regain a stable behavioral pattern. Sleeping posture (SP) and lying posture (LP) have been used as indicators for animal that are relaxed and well-acclimated to their environment.

At first, we executed a questionnaire survey to determine factors that comprise attitudes of farmers toward their jobs and dairy cows, and three factors were extracted. These were named as 'Positive beliefs to cows', 'Negative beliefs to cows' and 'Job satisfaction', respectively.

We collected blood samples every 5 min by using an automated blood sampling system and simultaneously recorded feeding, ruminating, and other behaviors using a video camera. Plasma non-esterified fatty acid (NEFA) concentrations continuously decreased during feeding and decreased temporarily during rumination.

As a stress response, the behaviors of 37 postpartum cows were observed when they were introduced into a new group. Milk samples for MC measurement and milk trait data were collected on the test day every 2 months after calving.
