Special Issue Information

Dear Colleagues,

The transition period in dairy cows is undoubtedly one of the key stages of the entire productive cycle of the dairy cow that determines the success of the cow's lactation, including health, milk yield, and fertility, and which defines the profit of dairy operations.

In this scenario, nutrition and feeding, cow comfort, and overall management are fundamental pillars that help to modulate the cow’s metabolic status and immunity (immunometabolism) in this challenging time.

Management of the transition cow should focus on minimizing the adverse impacts of negative energy and protein balance, the severity of hypocalcemia, other macro- and microminerals, a reduction in ketosis, the excessive release of non-esterified fatty acids (NEFA), hepatic lipidosis, displacement of the abomasum, inflammatory disorders (metritis and mastitis), and oxidative stress. In addition, the adaptation of the rumen to diets richer in starch, and therefore, a reduction in the risk of rumen acidosis, must be addressed. In the end, any of these management strategies will help in modulating the immune system, reducing the negative impact of the typical immunosuppression that occurs around parturition.

We invite original research and review papers that contribute new information on immunomodulation and metabolism during the transition period of dairy cows. Research and review papers may cover basic research topics, but manuscripts focused on practical management, including case reports, epidemiological studies, and field trials, are also encouraged and welcomed.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Dairy cows face several challenges during the transition period, and the administration of live yeast might be useful to mitigate this stressful condition. In the current study, the effects of live yeast administration on milk production, feed intake, and metabolic and inflammatory conditions were evaluated. Multiparous Holstein cows were enrolled in this randomized controlled trial and received either a control diet (CTR, n = 14) or the control diet plus 4 g/d of live Saccharomyces cerevisiae yeast (LSC, n = 14) from −21 to 56 days relative to calving. Dry matter intake, milk yield and composition, and rumination time were monitored daily. Blood samples were collected at −21, −7, 3, 14, 28, 42, and 56 days relative to calving to evaluate the metabolic profile. Fecal samples were collected at 56 days relative to calving to measure volatile fatty acids and feed digestibility. No differences between groups were observed in dry matter intake. Compared with CTR, rumination time was lower in LSC in after calving. Although there were no differences in milk components between groups, LSC had greater milk yield in the last three weeks of the study than CTR. No differences were observed in inflammatory markers or other plasma metabolites, except for β-hydroxybutyrate, which was higher in LSC, and reactive oxygen metabolites (ROMs), which were lower in LSC. Overall, these outcomes suggest that live yeast supplementation had some positive effects on milk yield and oxidative status. Full article
