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 (9-21 weeks (wks) of age) on pullet development and the subsequent performance, egg quality, and bone quality of Hy-Line Brown laying hens. A total of 256 pullets were randomly assigned to two treatments. Each treatment was replicated eight times with 16 pullets per replicate (n=8), which were fed ad libitum using either of the two CP regimens: (1) 14%-18% CP (fed with 14% and 18% CP from 9-17 wks and 18-21 wks, respectively); (2) 16% CP (fed with 16% CP from 9-21 wks of age). At 21 wks of age, eight birds per treatment were randomly selected to evaluate body composition and ovarian development. For quality analysis, eggs were collected at 28, 32, 36, and 70 wks. At 70 wks of age, eight hens per treatment were selected to evaluate bone quality. There were no treatment differences in pullet performance, body composition, and ovarian development at 21 wks. The dietary CP regimen during the rearing period (9-21 wks) did not influence laying performance during the laying period. There were no treatment differences in tibial and femoral quality at 70 wks. Egg quality results showed an inconsistent trend. It was concluded that the pullets fed with the low CP grower diet (14%) during the pullet period and a high CP pre-lay diet (18%) from 18-21 wks of age developed properly and had satisfactory laying performance. However, the rearing diet did not enhance bone quality.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"59 4","pages":"328-337"},"PeriodicalIF":1.5,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/02/51/59_328.PMC9596298.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40469046","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}

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 muscle cells because of their thick muscle layers, which enable easy analysis of the cells. Morphological observations and expression patterns of smooth muscle markers were confirmed. Next, we observed where the markers were localized in the gizzard tissue at E10, E15, and E18. Finally, the expression pattern of Cx43 in primary cultured smooth muscle cells from E15 gizzards was investigated. The analysis revealed the expression and localization of Cx43 and calponin 1 in the smooth muscle layers, and 3D analysis revealed dynamic changes in the localization pattern of Cx43 from E10 to E15. Cultured smooth muscle cells confirmed that Cx43 was expressed in the cell membrane and cytosol. In conclusion, Cx43 expression was identified in chicken gizzards at E10, E15, and E18, which was localized differently during development. The expression was broad at E10, and became restricted at E15 and E18. Primary culture of smooth muscle cells showed that Cx43 was present in the cell membrane and cytosol. This suggests that Cx43 is actively translated into the cytosol at E10, forming a hexamer, and shuttling the cell membrane to function as a gap junction.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"59 4","pages":"338-347"},"PeriodicalIF":1.5,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/88/1b/59_338.PMC9596294.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40688157","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}

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, it is not clear whether chickens have a gustatory perception of L-amino acids. Here, we found that chickens conditioned to avoid either L-Ala, L-Ser, or L-Pro solutions could successfully learn to avoid the corresponding L-amino acid solution in the conditioned taste aversion (CTA) test. Because CTA is a well-established learning paradigm generated specifically by pairing gustatory perception and gastrointestinal malaise, the present study suggests that chickens can sense L-amino acids by gustatory perception. In addition, we found that the expression of the T1R1 and T1R3 genes was significantly downregulated in response to chronic exposure to L-Ala solution, but not to acute oral stimulation. Taken together, the present study suggests that chickens have a gustatory perception of L-amino acids, and the expression of T1R1/T1R3 mRNAs in the oral cavity can be regulated by L-amino acid intake. Since chickens can detect L-Pro solutions, additional amino acid receptors, other than T1R1/T1R3, may be involved in L-amino acid taste detection in chickens.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"59 4","pages":"348-356"},"PeriodicalIF":1.5,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/46/5a/59_348.PMC9596290.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40469045","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}

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 examined using western blot analysis and real-time PCR quantification. Changes in SPRL content were strongly correlated with PRL mRNA levels. The increase in PRL content on day 17 of incubation may be caused by the increase in PRL mRNA levels on day 16 of incubation. Additionally, the effects of VIP on PRL release from the embryonic anterior pituitary gland were not observed until day 18 of embryogenesis. These results suggest that increased levels of PRL mRNA and PRL content in the anterior pituitary gland are closely correlated. However, the increased expression of PRL mRNA observed on day 17 and the initiation of PRL release from the anterior pituitary gland on day 19 were differentially regulated. According to the results of western blot analysis, the proportion of glycosylated PRL (G-PRL) and non-glycosylated PRL (NG-PRL) in the anterior pituitary gland at the end stage of development differed from the proportion of PRL released from the anterior pituitary gland. According to the results of two-dimensional western blot analysis, no isoforms with different isoelectric points were detected in the culture medium on days 19 and 20. These data suggest that the peptide chains of G-PRL and NG-PRL were not modified. In conclusion, the differentiation of PRL-producing cells and the maturation of the hypothalamus and anterior pituitary gland were completed at the end stage of incubation, and that different factors regulated the initiation of PRL mRNA expression before day 18 of incubation.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"59 4","pages":"364-370"},"PeriodicalIF":1.5,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/71/3d/59_364.PMC9596296.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40469047","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}

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, we determine whether fibril formation by the hen egg white lysozyme (HEWL) could be inhibited by conducting a thioflavin T assay followed by fluorescence and electron microscopy observations. The results demonstrated that four peptide specimens prepared by the hydrolysis of crude proteins from the egg white, egg yolk, chalazae, and eggshell membrane of hen eggs effectively inhibited HEWL fibril formation. Among the four specimens, peptides from chalazae exhibited the highest preventive ability. The superiority of chalaza peptides was also observed when fibril formation was assayed using a full-length human lysozyme and human amyloid β peptide 1-42, which is the key factor for the development of Alzheimer's disease. Our study of the fibrillization of the human lysozyme also showed that metal ions (Zn2+, Ca2+, Co2+, Mn2+ and Al3+) promoted fibrillization, and their effects were abolished by the peptide specimens (especially by chalaza peptides). Thus, we conclude that chicken-egg proteins could be a convenient source of therapeutic materials for amyloidosis.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"59 4","pages":"384-391"},"PeriodicalIF":1.5,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/d5/72/59_384.PMC9596292.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40688158","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}

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, leading to reduced immune responsiveness after inoculation. In this study, we first determined the freezing temperatures of a commercial W/O vaccine using freezers maintained at -10, -13, -15, and -20°C. The results showed that the W/O vaccine froze from -10 to -12°C. Next, we evaluated the effect on antibody level transitions (sample-to-positive ratio) in 46-day-old broiler chickens vaccinated with the W/O vaccine that was maintained at -20°C, 5°C, and -10°C, in that order. In addition, the effect on antibody value transitions was evaluated in 45-day-old broiler chickens vaccinated with the W/O vaccines that were frozen and thawed between -20°C and 5°C repeatedly or warmed to 45°C. In these experiments, no remarkable effect of the freeze-thawing or warming treatments on antibody value transitions was observed. These results suggested that the efficacy of the W/O vaccine was not significantly affected when placed in a frozen environment or left in a room temperature environment of 42°C or lower for approximately 5 d. These data indicate the possibility of expanding the temperature range for handling W/O vaccines.","PeriodicalId":16883,"journal":{"name":"Journal of Poultry Science","volume":"59 4","pages":"378-383"},"PeriodicalIF":1.5,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/47/de/59_378.PMC9596295.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40688155","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}

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), is generally thought to have propagated from north East Asia (Korea and north China) to ancient Japan. However, mitochondrial haplogroup D, which is abundant in Island Southeast Asia (ISEA) as well as the Pacific but relatively rare in other regions, can be observed in some Jidori breeds (e.g., Tosa-Jidori, Tokuji-Jidori) with high frequency, leading to speculation that chickens from ISEA or the Pacific also contributed genetically to JNCs. To test this hypothesis, we sequenced the mitochondrial genomes of Jidori breeds and conducted phylogeographic analysis. Our results indicate that the JNC Haplogroup D belongs to Sub-haplogroup D2, which is currently only observed in Xinjiang, northwest China, and not to Sub-haplogroup D1, which is widely distributed in the ISEA-Pacific region.
