The combined treatments also improved jejunal morphology, as indicated by increased villus height and villus height-to-crypt depth ratio (P < 0.05). In addition, the supplemented groups exhibited enhanced antioxidant capacity and modulated intestinal immune-related indices, as reflected by higher total superoxide dismutase, Glutathione peroxidase, Total antioxidant capacity, and Secretory immunoglobulin A levels (P < 0.05). The combined extract supplementation reduced serum IL-1β and IL-6 levels and Diamine oxidase activity while increasing <i>Claudin-1</i> expression compared with the control group (P < 0.05).

In this study, we evaluated the laying performance and egg quality among hens of three genetic origins (Canarian, Lohmann Dual, and Novogen BT), as well as post-laying carcass and meat characteristics. In addition, consumer panels were employed to undertake sensory evaluations of eggs and meat. Sixty hens fed a commercial diet were reared under traditional free-range conditions. The production of eggs was monitored from 20 to 74 weeks of age, after which, the hens were slaughtered for carcass and meat analyses. Growth trajectories of hens were assessed using the Gompertz equation, which revealed distinct patterns among the three genotypes. The Canarian breed was characterized by a later age at inflection (9.5 weeks) and reached a higher asymptotic weight (2.2 kg) than the Lohmann Dual (7.3 weeks; 1.5 kg) and Novogen BT (7.9 weeks; 1.7 kg) breeds. With respect to egg production, efficiency was lower in Canarian hens (feed conversion ratio > 8.2) than that in Lohmann Dual and Novogen BT hens (feed conversion ratio = 2.9-3.9), which is assumed to be associated with the brooding behavior of Canarian hens. Compared with the other assessed breeds, Canarian eggs were characterized by distinctive quality traits, including tinted shell coloration and higher redness (a*) and yellowness (b*) values. Similarly, the meat and skin of Canarian hens had higher yellowness (b*) values, indicating specific quality attributes. Sensory evaluation revealed comparable acceptability among the three breeds, although Canarian hens received higher scores for specific sensory attributes of meat, particularly aroma, juiciness, and greasiness.

Oral administration of CuSO₄ induces nausea and vomiting in some mammalian species and in pigeons. Although oral administration of CuSO₄ induces retching in chicks, whether it causes true vomiting or nausea-like responses remains unknown. This study examined whether intraoral, intracrop, and intragastric administrations of CuSO₄ induced vomiting, retching, and nausea-like responses in chicks (<i>Gallus gallus domesticus</i>). Food intake, crop emptying rate, and voluntary activity were used as indices of nausea-like responses. CuSO₄ limited food intake, irrespective of the administration route, and markedly reduced the crop-emptying rate. Voluntary activity remained unaffected by intraoral administration, but decreased following intracrop and intragastric administrations. Four of the six chicks exhibited retching after intraoral administration of CuSO₄; whereas intracrop and intragastric administrations failed to elicit this behavior. Similarly, CuSO₄ failed to cause any vomiting. These findings indicate that CuSO₄ does not act as an emetic agent in chicks; rather it induces nausea-like responses. Route-dependent effects further suggest that exposure within the oral cavity is required for the excretion of CuSO₄, possibly serving as a protective behavioral mechanism to reject irritant compounds before they enter the lower gastrointestinal tract.</p>","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"63 ","pages":"2026019"},"PeriodicalIF":2.1,"publicationDate":"2026-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13437258/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148679077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have examined the effects of circadian disruption on brain development in chickens, which are diurnal animals with genomic similarities to humans; however, adult chickens lack post-hatching parental care, which limits their utility in analyses of parent-offspring interactions. In this study, we investigated the potential use of Bengalese finches (<i>Lonchura striata domestica</i>) as model animals for circadian rhythm and physiological research. Given that the small size of Bengalese finches makes it difficult to implant nanotags directly, we developed and fitted specialized garments containing nanotags. After one week under experimental light cycle conditions, rectal temperature and weight were measured, and the activity recorded by the nanotags was analyzed. The nanotag garments did not impede Bengalese finch flight nor did they influence body temperature, weight, or whole-blood glucose levels. Finches housed under a 12-h:12-h light-dark cycle exhibited minimal activity during the dark phase and increased activity after the lights were turned on, reaching peak levels above 40 counts. In contrast, finches housed under constant 24-h light exhibited relatively continuous activity levels of 5-20 counts, with no distinct resting phase. The results demonstrate that locomotor activity rhythms in Bengalese finches are strongly regulated by environmental lighting conditions, and that nanotag placement using specialized garments enables non-invasive physiological and behavioral monitoring.
