Photo courtesy of Feed Institute of Chinese Academy of Agricultural Sciences Rumination is a unique digestion method of herbivorous animals such as cattle and sheep, but this ability is not innate.
When the ruminant behavior is established is an interesting scientific question
.
Recently, the ruminant feed innovation team of the Institute of Feed Research of the Chinese Academy of Agricultural Sciences conducted a systematic study on the establishment and development of ruminant behavior in newborn calves, and determined that the time when calves first appeared ruminant behavior was 15-20 days of age
Journal of Dairy Science
According to researcher Tu Yan, the chief scientist of the team, ruminant behavior is closely related to rumen health and digestive function, but few people pay attention to the time when calves first ruminate
.
The study used infrared cameras to observe the rumination behavior of calves and found that under the feeding mode of "milk + fine feed", calves' first rumination was mainly concentrated at 15-20 days of age
The research was supported by the Beijing Innovation Team of the Dairy Industry Technology System, the Innovation Project of the Chinese Academy of Agricultural Sciences and the Basic Scientific Research Business Expenses of the Chinese Academy of Agricultural Sciences
