Advances in Feed Additives for Enhancing Early Lactation Performance in Ruminants

Dear Colleagues,

The early lactation period is a crucial stage in ruminants, characterized by metabolic imbalances, immunosuppression, and variable milk production, all of which compromise health and productivity. Historically, antibiotics were routinely used in early lactation for pathogen control and inflammation management. However, given the risks of antimicrobial resistance and food safety, replacing antibiotics with feed additives has emerged as a dominant approach in livestock production. The proper utilization of nutritional additives helps to optimize energy and metabolism, boost immune function, and maintain intestinal health.

This Special Issue aims to highlight the role of feed additives in the early lactation period, investigating their mechanisms and impacts on ruminant health, metabolism, and milk production. By bridging research and practice, this Special Issue will support evidence-based strategies for sustainable ruminant production.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

• Nutritional regulation and metabolic improvements;
• Immunomodulation and stress resistance;
• Rumen health and fermentation enhancement;
• Molecular mechanisms of lactation performance;
• Antibiotic alternatives;
• Sustainability and environmental impacts.

We look forward to receiving your contributions.
