Using rumination time to manage health and reproduction in dairy cattle …
网页2021年10月21日 · Different authors have reported a range of rumination times (RTs) and patterns in dairy cattle. Welch reported a basic circadian pattern in rumination with cattle normally spending 8–9 h per day ruminating.
Review Invited review: Current perspectives on eating and rumination ...
网页2018年6月1日 · The process of chewing during eating and ruminating plays a vital role in maintaining high levels of feed intake and efficient digestive function in high-producing dairy cows. Ruminants chew their feed initially during eating, and swallowed feed is later regurgitated and remasticated through the process of rumination.
Rumination and its relationship to feeding and lying behavior …
网页2012年6月1日 · Rumination and lying times are positively associated, helping to explain why rumination peaks at night when cows are most likely to be lying down (and least likely to be feeding). However, we caution the extrapolation of our results to lactating dairy cattle, as our observations were limited to cows during the dry period.
A New Approach to Recording Rumination Behavior in Dairy Cows …
网页2024年8月26日 · Rumination behavior in cattle can provide valuable information for monitoring health status and animal welfare, but continuous monitoring is essential to detect changes in rumination behavior.
Relationships between milk fat and rumination time recorded by ...
网页Rumination time (RT) of individual cows can be measured with commercial rumination sensing systems, but our understanding of how daily RT (minutes per day) is related to milk fat production is limited. Our hypothesis was that between cows within a herd, greater RT would be associated with lower milk fat concentration.
Invited review: Current perspectives on eating and rumination …
网页This review provides a comprehensive understanding of the dietary, animal, and management factors that affect eating and ruminating behavior in dairy cows and presents an overview of the physiological importance of chewing with emphasis on recent developments and practical implications for feeding and …
Rumination activity of dairy cows in the 24 hours before and after ...
网页The objective of this study was to describe the short-term changes in rumination patterns in dairy cows immediately before and after parturition. In total, 17 cows were fitted with rumination sensors that were able to monitor rumination time, number of rumination boli, and number of rumination jaw movements.
Effects of extrinsic factors on some rumination patterns: A review
网页Behind the generic term “cattle”, the dairy cow is the main area of interest for rumination, followed by “behavior”, “performance”, “system”, and “milk production,” which highlights how this kind of research is strongly related to the productive system.
Heritability and genetic correlations between rumination time …
网页2018年7月17日 · So far, rumination has been used as a proxy for monitoring dairy cow health at farm level. However, investigating its genetic aspects as well as its correlation with other important productive traits may turn this management tool into a new informative selection criterion.
Assessment of Ruminating, Eating, and Locomotion Behavior …
网页Heat-stressed cows eat less and hence ruminate less, which results in fewer buffering substances entering the rumen; rumination is the primary stimulus for saliva synthesis.
