Regulatory mechanisms underlying drinking behavior have not yet been identified in chickens; however, the regulation of osmolality and water intake appears to be closely related. This study clarified whether wet feeding affects appetite, osmolality, and stress-related gene expression in the hypothalami of chicks. In Experiment 1, the effects of different wet feed percentages on the growth of broiler chicks were examined. Wet feeds were prepared by mixing either 0.25 g (20% wet feed), 0.667 g (40% wet feed), or 1.5 g (60% wet feed) of distilled water per g of commercial feed. Then, the wet feeds were offered to 4-day-old broiler chicks until 42 d of age. Forty percent wet feed significantly increased body, breast, and leg weights. In Experiment 2, 7-day-old broiler chicks were given either commercial starter feed or 40% wet feed until 21 d of age. Again, weights of the body, breasts, and legs were significantly increased by wet feeding. The total amount of water loss in the individual waterers was significantly decreased by wet feeding. No significant changes were observed in mRNA levels of the genes encoding appetite-regulatory peptides (neuropeptide Y and α melanocyte-stimulating hormone), osmoregulatory peptides (vasotocin and mesotocin), or stress-related peptides (corticotrophin-releasing factor) in the chicken hypothalamus. Overall, 40% wet feed improved growth without inducing thirst or hunger in broiler chicks. These findings suggest that wet feeding contributes to both meat yield and animal welfare during broiler production.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"62 ","pages":"2025008"},"PeriodicalIF":1.8,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11795110/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143382783","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}

The main objective of this study was to detect polymorphisms in the SLC24A5 gene of the Chinese yellow quail (Coturnix japonica) and analyze their effect on tyrosinase activity in skin tissue and melanin content in down feathers. The cDNA of the SLC24A5 gene was cloned by RT-PCR and subjected to Sanger sequencing. Potential single-nucleotide polymorphisms (SNPs) were screened using multiple sequence alignment. The screened nonsynonymous SNPs were genotyped across 265 Chinese yellow quails using the kompetitive allele-specific PCR method. The association of genotypes with tyrosinase activity in the skin and melanin content in down feathers was analyzed. The g.8884145A/G SNP was identified in exon 9 of the SLC24A5 gene, resulting in an Asp396Ala mutation. The mutant residue was predicted to be located inside the eighth transmembrane helix of the SLC24A5 protein, which is primarily responsible for recognizing Na+/Ca2+ ions. Mutant individuals had significantly lower total melanin content in the feathers and tyrosinase activity in dorsal skin, in spite of no significant difference in SLC24A5 mRNA expression in the same tissues. This study indicates that the g.8884145A/G mutation reduced tyrosinase activity by affecting the function of the SLC24A5 protein, which in turn decreased melanin content of down feathers in Chinese yellow quail.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"62 ","pages":"2025006"},"PeriodicalIF":1.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11779592/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143080455","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}

Therefore, in this study, we investigated the taste preference in chickens for Tre and the metabolism of this disaccharide. In a short-term drinking test, chickens preferred low concentrations of Tre solution while avoiding high concentrations. Instead, in a conditioned taste aversion test, chickens did not show taste aversion to Tre, implying that chickens do not have a sufficient taste for Tre. The initial feed intake rate increased when 0.5% Tre was added. Respiratory gas analysis revealed that intragastric administration of 1.0 M Tre weakly increased the respiratory quotient. Furthermore, approximately 50% of Tre was metabolized in chickens. These results suggest that chickens slightly taste the sweetness of Tre. Moreover, adding Tre to feed increases the chickens' initial appetite, and they use approximately 50% of Tre as an energy source. This information is relevant for using Tre alone or as a supplement in poultry feed.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"62 ","pages":"2025005"},"PeriodicalIF":1.8,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11737969/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143007137","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}

In mammals, CpG oligodeoxynucleotides (CpG ODN) stimulate the innate immune system via toll-like receptor 9 (TLR9). However, TLR9 is absent in birds; instead, TLR21 serves as the receptor for CpG ODN. While CpG ODN induce behavioral and physiological changes in mammals, there is limited research on their effects on behavioral and physiological parameters in birds. The aim of the present study was to determine whether intraperitoneal injection of K3, a synthetic class B CpG ODN, affected food intake, voluntary activity, cloacal temperature, blood constituents, and feed passage from the crop in chicks (Gallus gallus). Additionally, the effects of K3 (GC), which contains GpC motifs instead of CpG motifs, were investigated to determine the importance of these CpG motifs. Intraperitoneal injection of K3 significantly increased the mRNA expression of interleukin-1β, interleukin-6, interleukin-8, and interferon-γ in the spleen. These changes were not observed with K3 (GC) administration. Intraperitoneal injection of K3 significantly decreased food intake but did not affect voluntary activity. K3 also significantly increased cloacal temperature, tended to increase plasma glucose and corticosterone concentrations and significantly decreased feed passage from the crop. In contrast, K3 (GC) showed no effects on these parameters. These results demonstrate that class B CpG ODN is associated with anorexia, hyperthermia, and reduced feed passage through the digestive tract in chicks during bacterial and viral infections.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"61 ","pages":"2024025"},"PeriodicalIF":1.8,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11611325/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142801241","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}
