This study investigated whether freezing or warming water-in-oil (W/O) vaccines affected the immune responses of chickens. One of the conditions affecting the efficacy of commercially available animal vaccines is the storage temperature range. Previous studies have shown that the properties of some inactivated vaccines change owing to freezing, lea...

The effects of oxygen gas injection starting on day 17 of incubation (D17) in a chick shell-less culture system (cSLC) on the subsequent embryo development were examined on day 19 of incubation (D19). On D19 of cSLC, the plasma phosphorus and total cholesterol concentrations of the embryos were significantly higher (P0.05). The percutaneous oxygen ...

Amyloid fibrils, which are formed from aggregates of aberrant proteins, can cause various forms of amyloidosis (including Alzheimer's disease). Such disorders often occur in elderly populations and are suspected to be lifestyle related. Thus, it has been speculated that some foodstuffs could be beneficial for preventing amyloidosis. In this study, ...

Difference of onset of increase of PRL content in the anterior pituitary gland and plasma PRL concentration during the late stage of chicken embryogenesis is well known. To investigate the disagreement, changes in PRL content and PRL mRNA levels, and the effects of vasoactive intestinal polypeptides (VIP) on PRL release and PRL mRNA expression were...

Previous studies in mammalian obesity models have suggested that central transforming growth factor- β (TGF- β ) controls the gene expression of appetite-regulating neuropeptides and peripheral energy metabolism. In the present study, we investigated the possible involvement of central TGF- β /Smad signaling in feeding regulation in chickens. Centr...

Elucidating taste sensing systems in chickens is an important step toward understanding poultry nutrition. Amino acid taste receptors, type 1 taste receptors 1 and 3 (T1R1 and T1R3, respectively), are expressed in chicken taste cells, and chicken T1R1/T1R3 is activated by L-alanine (L-Ala) and L-serine (L-Ser), but not by L-proline (L-Pro). However...

The pullet phase is an important stage in the development of laying hens when the development of organs, including reproductive organs and bones, is rapid. However, in recent years, few studies have focused on this crucial stage. The purpose of this study was to evaluate the effect of a dietary crude protein (CP) regimen during the rearing period (...

Body measurement traits (BMTs), which are classical quantitative traits of vital responses to body growth, have been studied in pigs, cattle, and sheep for several decades. In chickens, BMTs mainly cover body slope length, keel length, chest width, chest depth, tibia length, and tibia diameter; however, their genetic markers are yet to be considere...

Japanese native chickens (JNCs) comprise approximately 50 breeds, making Japan a diversity hotspot for native chicken breeds. JNCs were established through the repeated introduction of chickens from foreign countries. Jidori, which is the generic name of JNC breeds whose ancestral morphology resembles that of their wild progenitor (red junglefowls)...

Smooth muscle cells are widely distributed in the digestive organs of chickens. They exist as single cells, but adhere to each other to function synchronously. In this study, the expression of the gap junction protein connexin 43 (Cx43) in chicken gizzards was investigated at embryonic days (E) 10, E15, and E18. Gizzards have an abundance of smooth...
