The distribution of the immunoglobulins IgG, IgM, and IgA in turkey serum, bile, egg white, egg yolk, intestinal secretions, and some intraocular tissues has been studied. Just as in the chicken and the pigeon, IgG is the most abundant immunoglobulin in the serum and IgA in egg white, intestinal secretions and bile. In addition, IgM was detected in serum and egg white, and IgG in egg yolk, iris, vitreous body, and aqueous humor. The discussion deals with the importance of using purified immunoglobulin fractions and heavy-chain-specific antisera in disease studies in the turkey, specially in the case of infectious diseases which lead to the occurrence of "rheumatoid factors".

Food allergens are defined by their stability during digestion, with allergenicity largely influenced by resistance to enzymatic hydrolysis. Ovalbumin (OVA), a major egg protein, is a significant contributor to food allergies, particularly in children. Our previous work demonstrated that high hydrostatic pressure (HHP) treatment reduces OVA allergenicity by disrupting conformational epitopes and altering its structure.

Bioactive peptides rich in branched-chain amino acids (BCAAs) are an effective way to alleviate fatigue conditions, but the deep mechanism remains unclear. This study investigated the anti-fatigue effect of branched-chain amino acid-enriched egg white peptides (BEWPs) through the gut-muscle axis by gut bacteria and untargeted metabolomic analyses. The results demonstrated that BEWPs enhanced exercise endurance and strength by also promoting gastrocnemius development in mice.

Edible films are significant in prolonging the shelf life of meat products. Herein, we prepared some edible coatings (EW/TNPCSs) based on egg white/chitosan/pectin as polymer matrix, containing tannic acid-nisin composite nano-crosslinker with antibacterial-antioxidant activities. The results of preservation indicated that the prepared EW/TNPCSs reduced the water loss of chilled pork and delayed the changes of taste, texture and surface color.

Bone damages in laying hens are of great concern in poultry farming. Besides various risk factors like housing systems or nutrient supply during egg production, it has often been hypothesized that genetically high-performing laying hens may be more prone to bone damages. The relevance of dietary support during the rearing period of pullets for optimal bone development has been little addressed so far.

The present experiment aimed to formulate four ointments that included mixtures of plant extracts (, , , and ), apitherapy products (honey, propolis, and apilarnil) and natural polymers (collagen, chitosan, and the lyophilisate of egg white) in an ointment base. : In order to investigate the therapeutic properties of the ointments, experimental in vivo injury models (linear incision, circular excision, and thermal burns) were performed on laboratory animals, namely Wistar rats. The treatment was applied topically, once a day, for 21 days.
