Intraperitoneal Injection of Cisplatin Induces Nausea-Like Responses without Vomiting in Chicks (Gallus gallus domesticus)
Cisplatin is an anti-cancer drug that causes nausea and vomiting as adverse effects. Cisplatin-induced responses have been widely used to investigate the mechanisms underlying nausea and vomiting in several mammalian species. Because nausea and vomiting are caused by a variety of factors, including…

Effects of α-dicarbonyl Compounds on the Differentiation of Chicken Embryonic Myoblasts
Glyoxal (GO) and methylglyoxal (MGO) are highly reactive alpha-dicarbonyl compounds (α-DCs) generated through multiple pathways of glucose metabolism. Both GO and MGO are cytotoxic to mammalian cells, and are implicated in the pathogenesis of several diseases, including diabetes. In mammalian…

Comparative Performance of Three Hen Genotypes for Dual-Purpose Egg and Meat Production in Free-Range Systems
Breed selection is a key factor for small- and medium-scale poultry producers, particularly regarding the adaptability of birds to local conditions, their productive performance, and product quality. In this study, we evaluated the laying performance and egg quality among hens of three genetic…

Effects of Intraoral, Intracrop, and Intragastric Administration of Copper Sulfate on Vomiting, Retching Behavior, and Nausea-Like Responses in Chicks
Nausea and vomiting are induced by environmental distress and pain; understanding their etiology can improve animal welfare in modern farm operations. Oral administration of CuSO4 induces nausea and vomiting in some mammalian species and in pigeons. Although oral administration of CuSO4 induces…

Effect of Carnosine Supplementation on Warmed-Over Flavor, Volatile Compounds, and Meat Quality in Ground Chicken Breast and Thigh Meat
Lipid oxidation produces an unpleasant warmed-over flavor (WOF) in meat. In this study, the antioxidant peptide carnosine (Car) was added to minced chicken breast and thigh meat, and its effect on WOF, volatile compounds, and meat quality during refrigerated storage was assessed. Breast and thigh…

Effects of Quercetagetin on Gut-Liver Axis Function and Cecal Microbial Diversity in Broilers via PINK1/Parkin-Mediated Mitophagy
Oxidative stress is a major constraint on broiler health and productivity. Mitochondrial dysfunction and gut–liver axis disruption play pivotal roles in this process. The present study investigated whether dietary quercetagetin (QG) alleviated diquat (DQ)-induced oxidative stress in broiler…

Feeding Preferences, Carcass Characteristics, and Plasma and Pectoral Muscle Biochemical Indicators in Racer and Shiqi Pigeons
Racer pigeons are renowned for their exceptional flying abilities, and Shiqi pigeons are meat pigeons prized for their tender and nutritious meat. This study investigated the physiological and metabolic differences between the two breeds under distinct breeding objectives by examining their feeding…

Parental Age is not a Decisive Factor Influencing Gut Development, Nutrient Utilization, or Growth Performance in Response to Supplementation with Multi-Enzyme Preparations in Broiler Offspring
Progeny from older breeder hens exhibit higher feed intake but less efficient nutrient utilization than those from younger breeders. Multi-enzyme supplementation (MES) can serve as a practical dietary intervention to address this challenge. This study aimed to assess the effect of broiler breeder…

Supplementation of 5-Aminolevulinic Acid Suppressed Body Weight Loss and Reduced Disease Severity During Eimeria tenella Infection in Broiler Chickens
This study aimed to evaluate the effects of 5-aminolevulinic acid (5-ALA) supplementation in broiler chickens infected with Eimeria tenella. To assess these effects, chickens supplemented with 20 ppm 5-ALA (5-ALA group) were compared with non-supplemented controls (control group). Sporulated E…

Effect of Centrally Administered Neuropeptide Y and α-Melanocyte-stimulating Hormone on Water Intake in Chicks
From an animal welfare perspective, thirst avoidance is an important criterion for the poultry industry. Neuropeptide Y (NPY) and α−melanocyte-stimulating hormone (α-MSH) play critical roles in regulating food intake, which is closely related to water intake in mammals and chickens. This study…

Role of Medullary AKT and p38 MAPK in Regulating Feeding of Broiler Chicks
In layer chicks, central administration of insulin and refeeding promote the phosphorylation of AKT and extracellular signal-regulated kinase (ERK) in the medulla oblongata. Broiler chicks consume more feed than layer chicks, suggesting distinct feeding regulation. This study aimed to clarify the…
