Abstract: The objective of this experiment was to evaluate the effect of two feeding levels and two breeds on the daily activity budget of indoor-housed lactating beef cows fed total mixed ration (TMR). We used a total of 20 cows from Parda de Montaña (PA, n = 14) and Pirenaica (PI, n = 6) breeds. To evaluate the feeding level, PA cows were fed the TMR at the maintenance level and in a restricted amount. To evaluate the breed effect, PA and PI cows were fed at maintenance. All cows were video recorded for 24 consecutive… Show more

The aim of the present study was to investigate whether the access to pasture affects the stereotypic behavior of Jersey cows kept in loose housing systems. Therefore, a total of 21 randomly selected Jersey cows housed in two different investigation farms were observed once a week for four weeks in winter and summer, respectively, using the focal sampling method. On every examination day, each cow was observed for 15 min and the amount (AP) and length (LP) of periods, in which the cows showed stereotypic behavior within this observation time, were counted. Wilcoxon signed rank tests were carried out to estimate differences between pasture access and no pasture access regarding AP and LP. Welch two sample t-tests were performed to detect differences in AP and LP between both investigation farms. The results of the study show significant differences between the option of pasture access and no pasture access regarding the values of AP and LP. The values of AP (p = 0.001) as well as the values of LP (p = 0.006) were lower when the cows had access to the pasture. No differences could be found between the investigation farms. It could be concluded that the access to pasture has a significant influence on the stereotypic behavior of Jersey cows. Further studies are needed to intensively analyze the causes of stereotypic behavior in Jersey cows.

In this narrative review, the authors summarise the relationship between stress and behaviour and how dairy cattle cope with stressors. Based on the available literature, the most common stressors in intensive dairy cattle farming, such as pain, disease, heat stress, poor comfort caused by technology, and social stress, are surveyed. The authors describe how these stressors modify the behaviour of dairy cattle, influencing their feeding patterns, social interactions, and overall well-being. Additionally, the review explores the effectiveness of various coping mechanisms employed by dairy cattle to mitigate stress, including physiological adaptations and behavioural responses. This review is a valuable resource for understanding and grading stress in dairy cattle through behavioural reactions. Elucidating the intricate interplay between stressors and behaviour offers insights into potential interventions to improve animal welfare and productivity in dairy farming. Furthermore, this review highlights areas for future research, suggesting avenues for more comprehensive behavioural studies to enhance our understanding of stress management strategies in dairy cattle.

This paper proposed a supplemental feeding pusher based on beef cattle's auxiliary feeding needs to solve the traditional feeding mode of manual work, labor intensity, and inconsistent manual work standards. Firstly, the conveyed feed particles movement process was established as a motion model and the basis of the design parameters of the screw conveyor was explained. ANSYS static analysis module was used to ensure that the structural parameters of the discharging device were reasonable, ANSYS vibration modal analysis module was used to verify the frame strength and stability. According to the theoretical design of the trial prototype, the control system with STM32F103RE microcontroller as the core was carried out. Finally, the orthogonal test was conducted with the screw shaft speed, sweeping roller brush height, and traveling speed as test factors; different parameters were set to verify the effect of supplemental feeding and pushing, and parameter optimization of the test results was carried out using Design-Expert software. The optional combination of working parameters was determined to be the feeding screw shaft speed 188 r/min, the sweeping roller brush speed 160 r/min, and the work speed 0.26 m/s. The test demonstrated that the residual feed width was 0.73 m, and the transverse coefficient of variation was 14.9%, which could satisfy the needs of auxiliary feeding for beef cattle. This study reduced feed waste and met the cattle feeding needs to the greatest extent, and it could provide a reference for auxiliary feeding machinery.
