MS-associated EAA has a direct influence on income and biosecurity expenses because it increases cracked and degraded eggs, increases labour costs for sorting and cleanup and decreases hatchability through higher embryonic mortality when shell integrity is compromised. EAA manifests as irregularities at the egg’s apex, including thinning, increased translucency and susceptibility to cracks. These defects lead to increased egg breakage and spoilage, directly leading to degrading egg quality and marketability.

Etiology and Transmission:
Mycoplasma synoviae, belongs to the Mycoplasmataceae family and is fastidious about its culture conditions as it requires serum and NAD on modified Frey media. The pathogenicity of strains varies due to immune evasion, adhesins, sialidase activity, nitric oxide generation and antigenic diversity.

Fig. 1. Transmission of M. Synoviae
The host range of the MS infection includes chickens, turkeys, ducks, geese, guinea fowl, pheasants, quail and psittacines. Transmission occurs via both vertical and horizontal route. Vertical transmission takes place through transovarian infection, leading to early chick exposure, while horizontal transmission occurs via aerosol spread, respiratory secretions, fomites and human activity. Once introduced, the infection tends to persist, as infected flocks become lifelong carriers. Multi-age layer systems further support its persistence and contribute to episodic clinical outbreaks.

Pathogenesis:
M. synoviae primarily enters the host through the respiratory tract, with the upper respiratory mucosa serving as the initial site of colonization. With the help of specialized surface proteins and adhesions the organism attaches to the epithelial cells which help it to evade mucociliary clearance. From the respiratory tract, it can spread locally, causing tracheitis, airsacculitis and respiratory distress. In some birds, the pathogen disseminates via bacteraemia, reaching synovial membranes and joints, where it induces inflammation. This leads to synovitis, characterized by swelling, pain and lameness, often accompanied by exudation of yellowish synovial fluid. The organism may also localize in the tendon sheaths and bursae, producing tenosynovitis. Co-infections with other respiratory pathogens (e.g., E. coli, NDV and IBV) exacerbate disease severity. Chronic infections are common and affected birds may become carriers, serving as reservoirs for flock-to-flock transmission.

Clinical Signs:
Mycoplasma synoviae most commonly causes subclinical upper respiratory infections or infectious synovitis and tenosynovitis, while in layers it is also associated with eggshell apex abnormality (EAA) syndrome, characterized by thin, rough, translucent shell apices and intermittent production loss (Feberwee et al., 2009). The clinical expression of the disease is often expressed by stress and co-infections with pathogens such as infectious bronchitis virus (IBV), Newcastle disease virus (NDV) and Escherichia coli (Lockaby et al., 1998).

Affected birds may show mild respiratory involvement, including slight tracheal rales and sinusitis which are more evident under poor air quality or concurrent respiratory infections. The musculoskeletal form is marked by lameness, reluctance to walk, swelling of the hock joint, wing joints and footpads with exudative tenosynovitis of tendon sheaths and sternal bursitis. In systemic or severe cases, signs include depression, inappetence, ruffled feathers, weight loss and pale to cyanotic head parts, with occasional vasculitis and keel bursitis. Morbidity typically ranges from low to moderate, while mortality is generally low but may increase in the presence of secondary bacterial infections, wet litter, cold stress and immunosuppression.

Post Mortem Lesions:
– Respiratory tract:
– Mild to moderate airsacculitis with thickening, opacity and presence of turbid or caseous exudate.
– Mucoid tracheitis and sinusitis (especially when complicated by co-infections).
– Joints and musculoskeletal system:
– Synovitis: Swollen joints (particularly hock, wing and foot joints) with accumulation of yellow to serofibrinous exudate.
– Tenosynovitis: Inflamed tendon sheaths filled with exudate.
– Sternal bursitis (breast blisters) with fibrinous to caseous material.
– Systemic involvement:
– Generalized fibrinous polyserositis in some cases, especially with secondary E. coli infection.
– Emaciation and poor body condition due to chronic disease.
– Eggshell apex abnormality (in layers):
No specific gross lesion in reproductive tract, but post-mortem examination may reveal rough, thin and translucent apices of eggshells in affected flocks.

– Diagnosis:
Diagnosis of MS relies on combination of clinical observation, serology, microbiology and molecular techniques. Observation of respiratory signs such as sneezing, coughing and nasal discharge, along with joint or tendon swelling indicative of synovitis or tenosynovitis and specially in layers, eggshell apex abnormalities like thin, rough or translucent apexes can be observed.
However, clinical signs alone are not definitive, as they can overlap with other infections like NDV, IBV or E. coli.

Serological tests, including ELISA, rapid plate agglutination (RPA) and hemagglutination inhibition (HI), are useful for flock-level monitoring, though maternal antibodies and past exposure can complicate interpretation. Microbiological isolation from choanal or tracheal swabs and synovial fluid using specialized media allows definitive identification of MS, but the process is slow and prone to contamination. Molecular methods such as PCR and real-time PCR offer rapid, sensitive and specific detection of MS DNA, even at low bacterial loads. For accurate diagnosis, a combination of clinical assessment, serology and molecular confirmation is recommended, especially in flocks showing respiratory disease, joint swelling, or eggshell defects.

Treatment
Along with careful use of antibiotics, proper management practices and vaccination strategies are very important in Mycoplasma synoviae management. Treatment typically relies on antimicrobials such as tylosin, tiamulin, doxycycline or enrofloxacin, which can reduce bacterial load and clinical signs, but complete eradication is difficult due to intracellular persistence. Widespread and indiscriminate antibiotic use has led to antimicrobial resistance (AMR) in MS strains because of these challenges, thus, vaccination plays a central role in flock protection, lower bacterial shedding and prevent eggshell apex abnormalities in layers.

Prevention and Control:
Prevention focuses on biosecurity measures, including sourcing MS-free breeders, controlling movement of personnel and equipment and minimizing stressors that predispose birds to infection. Integrated control combining vaccination, strict biosecurity, monitoring via serology or PCR and responsible antimicrobial use is essential to minimize economic losses, maintain flock health and reduce the risk of AMR development. Thus vaccination, combined with good biosecurity and management practices can control MS spread, minimizing antibiotic reliance and maintaining flock productivity.

A recent research program highlights that micro-encapsulation of seaweed and plant extracts can stimulate digestive functions, improve performance, and reduce feed costs, addressing current egg industry needs.

The egg industry grapples with key challenges in optimizing nutrition and profitability for laying hens. One significant hurdle involves efficiently producing eggs while maintaining bird health and well-being. Sustainable practices, such as efficient waste management and reducing the environmental footprint, are essential to address growing concerns about the environmental impact of egg production. To tackle these issues and enhance the performance of laying hens, strategies have emerged. These include formulating balanced diets with alternative protein and energy sources, exploring feed additives like enzymes, microbials, phytogenics, and seaweed extracts. Enzymes, such as phytase, improve nutrient utilization, while probiotics and prebiotics support gut health, enhancing feed conversion and disease resistance. Natural phytogenics provide antioxidants, affect the microflora profile, and improve digestive functions, ultimately leading to increased egg production and improved egg quality. Seaweed bioactives (so called-phycogenics), contribute as well to better gut health of animals. These strategies address challenges in egg production and meet consumer expectations for high-quality, nutritious eggs, all while promoting sustainable and eco-friendly practices.

The latest benchmark for phytogenic feed additives
Lately, a feed additives company has introduced an innovative product, NUQO©NEX (NQ), comprising metabolites sourced from both plants and algae (referred to as phytogenic and phycogenic, originating from the Greek words ‘phytos’ for plant and ‘phycos’ for algae). These metabolites are shielded by a unique micro-encapsulation technology. The utilization of micro-encapsulation has become imperative in the realm of phytogenic feed additives to mitigate the volatility of natural compounds. While the term ‘encapsulation’ is increasingly generic, it is crucial to discern authentic technology that not only safeguards but also effectively releases active ingredients, setting it apart from rudimentary methods like silica absorption or light-agglomeration, which may suffice for various compounds but fall short in preserving delicate phytogenics like essential oils.

It is of utmost importance to delve into the manufacturing technology underpinning each product, rather than solely relying on surface-level claims. With its notably high concentration of active components and remarkable stability, this novel solution assures a precise release in the digestive tract and offers a cost-effective dosage unlike any other currently available. This technology has been meticulously developed to optimize poultry performance and can serve as an alternative growth promoter or a means to enhance feed conversion ratios and overall performance, ultimately resulting in an improved return on investment for poultry operations.

Numerous trials have validated the effectiveness of this technology in enhancing the performance of laying hens across diverse contexts and geographic regions. Concurrently, scientists have conducted assessments to gauge the technology’s precise influence on feed digestibility. This research aims to provide formulators and nutritionists with greater flexibility in their decision-making processes.

Enhancing Feed Digestibility in poultry
In a recent study conducted at the University of Berlin in Germany, researchers undertook a comparative analysis of four treatments: a negative control, two commercial products incorporating phytogenics (referred to as P1 & P2), and a novel technology, NUQO©NEX (NQ). The findings revealed that the NQ treatment not only enhanced the digestibility of nutrients like crude fat, crude protein, and starch but also contributed to increased mineral digestibility, including crude ash, calcium, and phosphorus, when compared to the negative control. The other two solutions also improved the digestibility of certain nutrients and minerals but to a lesser extent than NQ. Notably, the NQ treatment exhibited the most pronounced effects on nutrient and mineral digestibility, resulting in the highest overall performance improvement. In sum, the NQ treatment demonstrated enhanced feed digestibility, ultimately leading to improved performance, in contrast to conventional products relying on phytogenics. This underlines the significance of the formulation’s composition (comprising both phytogenics and phycogenics) and the influence of manufacturing technology (micro-encapsulation) on product stability and release within the digestive system.

Concrete impact on feed costs with a conservative matrix value
The NQ technology underwent extensive testing in various global regions, including Asia, Europe, and Latin America, to evaluate its impact on the performance of laying hens. Additionally, to offer maximum flexibility to nutritionists and formulators, diverse scenarios were examined, involving the application of feed additives either “on top” of the formulation or using a “matrix value” approach, allowing adjustments to the feed formulation to reduce costs by decreasing energy and protein content. Two recent trials were conducted at Kasetsart University in Thailand under the guidance of Professor Yuwares.

In an experiment, the NQ technology was used with a “matrix value” at 75 ppm. Three treatments were tested: 1) an initial control diet [C0], 2) a second treatment that consisted of the same control diet but with reduced energy and protein content (-23 kcal/-0.25% dig.Prot) [NC], and finally, 3) a third treatment was given to animals based on the control diet, with reduced energy and protein content (-23 kcal/-0.25% dig.Prot) along with the NQ technology at 75 ppm [NC+NQ]. In this case as well, the experiment consistently delivered expected results. Applying a matrix to the control diet (NC) adversely affected laying percentage, egg mass, and FCR but did not alter feed intake when compared to the control. Applying NQ technology with a matrix value (NC+NEX) helped to restore layer performance, with the laying percentage even slightly surpassing that of CO.

Beyond performance indicators, additional assessments highlighted the influence of the NQ technology. Researchers observed a decrease in both fatty liver scores and occurrences. Moreover, there was an enhancement in eggshell thickness, whether the technology was used in a diet, with or without a matrix value.

Opt for the latest, science-backed technology to safeguard profits
In the evolving landscape of the egg industry, the NQ technology emerges as a revolutionary solution. By seamlessly combining exclusive ingredients sourced from both plants and algae, it offers a distinctive advantage. What sets this technology apart is its genuine micro-encapsulation method, ensuring the safe and efficient release of active components. Through extensive trials, the remarkable effects on laying hens’ performance, improved feed digestibility, enhanced egg quality, and notable reduction in costs have been demonstrated. NQ technology is not just one more phytogenic feed additive, but rather the most advanced nature-based technology for optimizing laying hens’ performance at competitive cost. It serves as a cornerstone for the future of egg production, delivering unparalleled advantages to producers and championing healthier, more sustainable laying hens’ operations.
