We measured the body weights of 1,384 KNC breeders at 1-140 days of age at two-week intervals. The age at first egg laying, hen-day and hen-housed egg production, and the egg weights were investigated. Correlation coefficients between the body weight and egg production traits were analyzed. The results showed that the correlation coefficients between body weight and age at first egg laying were significantly positive before 4 weeks, but negative after 8 weeks of age. The correlation coefficients between body weight and egg production rate were estimated to be negative before 8 weeks and positive after 12 weeks of age. Coefficients of hen-day and hen-housed egg production were similar. There was little correlation between body weight and egg weight at 32 weeks of age, whereas a low positive correlation was with egg weight at 50 weeks. In conclusion, there was little correlation between body weight and laying performance before 8 weeks of age, whereas a significant positive correlation was with body weight after 12 weeks. The results suggest that as the chick's weight increases in the late growing stage, sexual maturity is faster, the egg production rate is higher, and the egg weight increases. Therefore, the weight management of KNC female breeders is very important in the late growing stage, and the body weight of chicks must be maintained above the standard weight.","PeriodicalId":17845,"journal":{"name":"Korean Journal of Poultry Science","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73895693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using 22 paternal chickens and 329 offspring, the paternal reproductive performance such as fertility, embryo mortality, and hatchability, as well as the offspring production performance such as survival rate, body weight, and weight gain were analyzed. Telomere length was analyzed through quantitative fluorescence in situ hybridization using lymphocytes. No significant differences were observed in fertility, embryo mortality, and hatchability between paternal chicken telomere lengths ( P<0.05 ). These results indicate that paternal telomere length had a weak negative correlation with fertility and embryonic death rate but a weak positive correlation with hatchability. The correlation coefficient between paternal telomere length and offspring survival rate was r=0.17 ( P>0.05 ). The group of offspring with long paternal telomeres showed relatively poor growth performance. Moreover, a significant negative correlation was estimated between paternal telomere length and offspring growth performance ( P<0.05 ). The correlation coefficient between paternal and offspring telomere lengths was r=0.075 ( P>0.05 ). In conclusion, there was a weak association between paternal telomere length and reproductive performance, offspring survival rate, and offspring telomere length, respectively. However, paternal telomere length and offspring growth performance showed a negative relationship. Such results could be due to the re-extension of telomere length by telomere reprogramming in the early embryonic stage and the different degree of telomere shortening between individuals with increasing age after birth.","PeriodicalId":17845,"journal":{"name":"Korean Journal of Poultry Science","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80579466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the mid-1990s, abundant dinosaur fossils have been found in China and various other parts of the world. Research articles on phylogenetic, evolutionary, and genomic studies of fossil taxa show that birds are living theropod dinosaurs. This review describes the link between birds and dinosaurs based on studies of their skeletal structures, feathers, respiratory organs, chromosomes, and metabolism.

One hundred and twenty 1-day-old birds (Ross 308) were allocated to two dietary treatment groups with six blocks in a randomized complete block design. The two experimental diets consisted of a corn-soybean meal-based basal diet and a diet with 0.5% TO powder instead of cornstarch in the basal diet. After feeding the experimental diets for ten days, all birds' body weight and feed intake were measured, and representative eight birds were selected from each treatment group. Small intestinal lamina propria cells were isolated using flow cytometry to examine the frequency of immune cells. Cecal feces were harvested for 16s rRNA gut microbiota analysis and fecal IgA levels. Here, we found that 0.5% TO supplementation increased CD3 + CD4 + T cells in the small intestine, but decreased CD3 + CD8 + T cells in the small intestine. Gut microbial analysis showed that TO supplementation significantly increased the alpha diversity of the gut microbiome. Taxonomic analysis showed that TO treatment increased the abundance of Firmicutes and decreased that of Bacteroidetes at the phylum level. The distribution of Enterobacteriaceae containing many harmful bacteria at the family level, was lower in the TO group. In the LEfSe analysis, the TO group had a significantly enriched abundance of Agathobaculum at the genus level. Overall, results show that Tetradesmus sp. supplementation influences intestinal T-cell immunity and induces the expansion of beneficial gut microbes in pre-starter broiler chickens.","PeriodicalId":17845,"journal":{"name":"Korean Journal of Poultry Science","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74330386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, chimeric peptides (cpNK) of chicken and pig NK-2 and cpNK-derived peptides (cpNK-a1 and cpNK-a2) were synthesized, and their antimicrobial effects against various pathogenic bacteria such as Escherichia coli, Salmonella spp., Listeria monocytogenes , Staphylococcus aureus , and methicillin-resistant Staphylococcus aureus (MRSA) were investigated. The structure of chimeric peptides from chicken and pig NK-2, cpNK, include α -helix like NK-2 and peptide net charge was +9 like porcine NK-2. The cpNK peptide showed powerful bactericidal effects against most bacterial species, including MRSA, especially against gram-negative bacteria. Furthermore, cpNK-derived short peptides, cpNK-a1 and a2 also showed bactericidal activity, but the effects were weaker than those of cpNK.

In cell culture, it is well known that the culture medium has a significant influence on cell growth and maintenance of cell characteristics. This study aimed to adjust the culture medium to make it more suitable for QM7 muscle cells. A culture medium was prepared by adding 2% chicken serum (CS) instead of 10% tryptose phosphate broth (TPB) to the conventional culture medium. In the culture medium prepared with CS, the QM7 muscle cells changed from a pointed, thin to a broader shape. In addition, they grew and divided more rapidly in the new culture medium than in the conventional culture medium. The number of cells increased faster in the CS-containing culture medium from day two after passaging, and significantly increased from day three. The muscle cells grown in the medium containing CS maintained their undifferentiated state prior to differentiation. Myotubes formed well when the cells were maintained in CS-containing medium, resulting in a longer length and uniformity. According to the above results, it is clear that the culture of QM7 myocytes using a medium containing CS rather than TPB helps obtain better results in cell maintenance and differentiation.","PeriodicalId":17845,"journal":{"name":"Korean Journal of Poultry Science","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89486348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
