ADSA 2021 Annual Meeting Webinar Series

Probiotic bacteria, particularly lactobacilli, play an important role in human health. Recently, the lactobacilli taxonomy underwent extensive revision, including the addition of 23 new genera, which will have a significant impact on future research and regulatory approaches. Fermented dairy products are an important delivery system for probiotic cultures. The pairing of probiotic cultures with fermented dairy products appears to have synergistic benefits for gut health and allows new opportunities for optimization. In addition, prophages have been shown to play an important role in the ecology of probiotic cultures in vivo. In this symposium, we will explore recent developments in understanding Lactobacillus taxonomy, the role of prophages, and the synergism of probiotic cultures and milk and the effect of this synergism on activity in the human digestive tract.

In the last 40 years, there has been growing interest from the scientific community in milk quality and milk processing at the farm level in dairy production from mares and jennies, as well as the effects of equid dairy products on human health (e.g., microbiome, immunity, cancer, infectious diseases, skin disorders). This symposium aims to furnish an overall analysis on knowledge in this area and highlight the scientific challenges in terms of improving milk production from both a quantitative and a qualitative point of view (e.g., milking management, suckling foal management, feeding management, animal welfare, genetic selection), implementing processing techniques to ensure longer shelf life, and increasing dairy product variability on the market through scientifically sound studies of the effects on human health.

Enteric methane is a major greenhouse gas resulting from feed digestion by ruminants. Societal attention to climate change continues to emphasize the need for enteric methane mitigation from milk production systems. The development of successful enteric methane mitigation strategies requires interdisciplinary research in ruminal microbiology, ruminant nutrition, breeding and genetics, health and well-being, farm technology, farm systems and modeling. Attendees to this symposium will learn about future prospects for research and advances from the last decade that already contributed to or hold potential for developing technologies and practices that reduce enteric methane emissions from dairy animals.

The mammary gland is a modified skin gland and thus plays a role in the innate immune system; moreover, the adaptive immune response is important during development and health. Understanding mammary immunity and how management, nutrition, genomics and environment affect it will enhance health, production and welfare of the dairy cow.

Speakers and presentation titles:
Metabolic transitions and lipid mediators as modulators of mammary gland inflammation and oxidative stress. - Andres Contreras
Environmental effects on mammary immunity and health. - Geoffrey Dahl
Applications of nutritional immunology to improve mammary health. - Turner Swartz and Barry Bradford
Milk, teat, and skin microbiomes and their role in mammary health and immunity - Erika Ganda
