In this session, we'll dive into the importance of calcium and negative DCAD in dairy cattle nutrition and reproduction. You’ll learn how managing these elements in the diet can help improve reproductive performance and prevent health issues. We’ll also cover how to identify and address management challenges associated with negative DCAD and calcium levels, providing actionable insights to optimize your herd's overall success.

Statistical Process Control (SPC) functions can monitor any bird health metrics that are measured: presence/absence, load, health scores, etc. SPC Systems combine multiple SPC functions to monitor different types of changes. SPC Systems can detect smaller changes, and can detect them more quickly and more reliably than individual SPC functions. -

There are different additives used to improve intestinal health and performance, eliminate or at least mitigate lots of predisposing factors or boost birds immune system towards pathogens. Enzymes (phytase and NSP enzymes), some vitamins (such as vit A, E, D3, niacin) and trace elements (like Zn and Se), probiotics, prebiotics, phytogenics (for example essential oils, polyphenols or saponins), short and medium chain fatty acids. The question is...which solutions are right for my flocks?
Unfortunately, there is no straight and simple answer. We need to understand each additive's specific mode of action and pick the one that best addresses the conditions and challenges we face.
When it comes to feed additives that improve intestinal health, a main attribute is inflammation management or anti-inflammatory properties. A desirable effect is also stimulation of the specific immune response towards different pathogens instead of non-specific inflammatory reactions, which are less efficient and often detrimental. Feed additives that boost intestinal health mitigate (prevent or alleviate) tissue stress and damage by, for example, dealing with antinutritional factors or having antioxidant effect.
Some additives have specific trophic properties over the intestinal mucosa, in which way they boost the mucosal function – absorption of nutrients and barrier for pathogens and toxic substances.
On the other side, some additives support the state of eubiosis or balance between the microorganism – in our case, the bird and its microflora. They might have a direct effect on the host metabolism by reducing stress and inflammation, driving metabolism to more catabolic versus anabolic processes.
Besides, most of the feed additives have additive or even synergistic effects that one could leverage on.
What You Will Learn:Define the components of intestinal integrity and review different nutritional strategies and feed additives helping to improve the intestinal barrier function, maintain balanced state of the intestinal microflora and tolerance to inflammation to improve performance and reduce the need of antibiotic treatments on the field. How to improve intestinal integrity by adjusting our feed specifications (protein, fibers, fat and minerals), dealing with main antinutritional factors, feed structure and raw materials’ quality. -
Dr. Mike Kogut, research microbiologist with the USDA Agriculture Research Service, introduces the intestinal trio and the relationship between gut microbiota, metabolites and immunity, including detailed discussion of inter-organ communication in the gut and regulation of tissue physiology. He further explores host defense mechanisms for disease resistance and disease tolerance, and how metabolism can manipulate host defenses.

PRESENTED IN ENGLISH. INTERPRETATION IN CHINESE.
Although not a novel disease, coccidiosis is still one of the most economically important veterinary problems in poultry production. According to 2020 data, coccidiosis contributes to more than $14 Billion of annual losses.
Due to their biology, coccidia could not be eradicated from poultry farms. Thus, coccidiosis requires uninterrupted and well-directed management.
What You Will Learn
The first prerequisite of successful coccidiosis management programs is having precise monitoring in place. A review of the arsenal of tools to manage coccidiosis, and how to use them in order to achieve optimal efficacy of coccidiosis control in the short- and long-term, keeping in mind the specifics of each operation. How Eimeria develop resistance toward different anticoccidial products, and how to assess the specific sensitivity patterns of field Eimeria strains in order to build an efficient program for specific conditions. -

The current H5N1 High Pathogenicity Avian Influenza (HPAI) virus is genetically diverse, with this Eurasia lineage of virus producing the first outbreaks in 1996 in domestic geese in China. The genetic clade 2.3.4.4b has spread intercontinentally between Asia, Europe, the Middle East, Africa and North America, causing major infections in wild aquatic birds—and in some species, such as common cranes and pelicans—major die-offs and outbreaks in backyard, village and commercial poultry in Asia, Europe, the Middle East, Africa and North America. Control is best to utilize biosecurity practices and prevent introduction into poultry premises. Some countries are utilizing vaccine as an additional tool in the control. -
