Special Issue Information

Dear Colleagues,

Nowadays, the dairy sector is reaching a crossroads that could soon lead to a paradigm shift. Public opinion is seriously concerned about its polluting impact and is also beginning to question the long-term ecological sustainability of milk production. In addition, milk consumers are increasingly demanding improvements in the welfare of dairy cattle, with some production systems having their days numbered. At the same time, stakeholders are trying to guarantee that these pivotal changes do not compromise the economic viability of dairy farming, as they face rising feed, energy, water, and labor costs.

Therefore, dairy production can only have a future if it reduces its polluting impact, if it decreases or uses more efficiently the resources it consumes, and if measures are implemented to effectively ensure the welfare of dairy cows. Hence, there is a clear urgency in implementing solutions that address these problems, and the most welcome are those ones that approach these issues together.

The purpose of this Special Issue is to publish original research articles or reviews on strategies that can contribute to more economically and ecologically sustainable dairy production that also promotes animal welfare.

Hematology RIs help clinicians and researchers determine whether a hematology parameter is abnormal, which plays an important role in animal health surveillance. China is one of the largest dairy producers in the world, with millions of Holstein cows. However, there has been no published data on hematology RIs for dairy cows in China yet. Therefore, the aim of this study is to establish updated and accurate RIs for Holstein cows in southern China. To increase the accuracy of the RIs, we collected blood samples from 786 Holstein cows and analyzed 25 hematologic variables. The RIs for Holstein cows were established using the 95% percentile RIs according to the American Society of Veterinary Clinical Pathology guidelines. The effects of different ages, parities and lactation stages were also checked in this study. The data of 21, 22 and 19 out of 25 hematology parameters were significantly different between different ages, parities and lactation stages, respectively. Furthermore, the hematology RIs of separate subclasses according to different ages, parities and lactation stages were generated. Hematology RIs according to ages and lactation stages, as well as parities and lactation stages, were also assessed. Together, our results confirm that hematology RIs for cows vary by ages, parities and lactation stages. The present study helps to fill the gap in hematology RIs for Holstein cows in southern China, and our data may serve as a very useful tool for monitoring the health and welfare of dairy cattle in China.
