The survival rate and telomere length were measured as vital markers. Telomere length was analyzed via quantitative fluorescence in situ hybridization method using the lymphocytes of 466 chickens. We found that the telomere length decreased linearly with increasing chronological age in all chicken breeds. Telomere length and telomere shortening rates (TSR) were significantly different among the chicken breeds after 20 weeks of age ( P <0.01). Rhode had the longest telomere length and the lowest TSR, whereas Cornish had the shortest telomere length and the highest TSR. In terms of TSR, the telomere length of 50-week-old chickens was half of that of 8-week-old chickens. There was also a significant difference in survival rates among the breeds. Both Rhode and Korean Ogye had the highest survival rates, while Cornish had the lowest. There was a significant positive correlation between survival rate and telomere length, and telomere length in old age showed a higher correlation with survival rate than that in young age. Therefore, it is considered that TSR is more closely related to survival rate than the telomere length. Based on the telomere dynamics and survival rates of 12 Korean native chicken breeds, it was concluded that the Rhode breed and Cornish breed had the highest and lowest vitality, respectively.","PeriodicalId":17845,"journal":{"name":"Korean Journal of Poultry Science","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83842002","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}

This result showed there was no difference on the fecal excretion per feed intake of laying hens supplemented with phytase levels in the diets. On the other hand, the excretions of dried feces, N, P 2 O 5 , and K 2 O were significantly ( P <0.05) reduced in 2,000 FTU/kg treatment than 0, 1,000 FTU/kg treatments. There was no difference on the compost composition and nutrient contents in compound fertilizer using compost from hens fed dietary phytase levels. However, compost content in the fertilizer was 69.6 ∼ 71.6% when compost of 25 ∼ 30% moisture content was used, and 13.0 ∼ 47.1% at compost of 40 ∼ 60% moisture content.

Parent stocks produced from a nine-combination association from five pure line strains (C, D, F, K, and Y) were used. The body weight analyses results showed that the CY combination had the highest body weight (1,604.9 g) and the DK combination had the lowest (1,424.4 g). The average age at first egg of the nine combinations was 118.6 days; however, that of the YD combination was 111.6 days, making it the fastest growing combination, whereas the DK combination was the slowest, at 126 days. Hen-day egg production was 74% or more for the CF, CK, and DK combinations. The DK combination hens showed excellent persistence in egg laying. Hen-housed egg production exhibited results similar to those of hen-day egg production. Egg weight was significantly higher in the DK combination than in the other combinations and was observed to increase from 20 (43.9 g) to 40 (58.1 g) weeks. The egg quality analyses results showed that the combinations based on the F and K strains had a bright eggshell color, with relatively high egg weights. Eggshell strength and thickness were the highest in the DK combination (3.8 kg/cm, 0.38 mm). In summary, the CF and DK combinations showed excellent egg production ability and egg quality, while the YC, YD, and YK combinations with the Y strain as the paternal strain exhibited poor performance.

One-day-old Cobb and Ross broilers were raised for 35 days in conventional and animal welfare farms with, amongst others, different floor sizes, stock densities, and ammonia concentrations. One-dimensional H nuclear magnetic resonance, orthogonal partial least squares-discriminant analysis (OPLS-DA), and pathway analyses were performed to analyze the metabolomic properties of broiler meat. For breast meat, only those from the Ross strain could be separated according to the environment in the OPLS-DA plot. Ross breast meat from animal welfare farms showed significantly higher acetate, anserine, creatine, and inosine monophosphate content than those from conventional farms (P<0.05). In contrast, for thigh meat, the Cobb strain was differentiated using OPLS-DA. The contents of five metabolites, such as glucose and lactate, were higher in thigh meat from animal welfare farms; however, nine metabolites, including seven free amino acids, were lower compared to those from conventional farms (P<0.05). Pathway analysis was performed to interpret the biological changes in chicken meat based on environmental factors. The results indicated that the animal welfare environment led to significant changes in four metabolic pathways in Ross breast meat and in 20 metabolic pathways in Cobb thigh meat (P<0.05). In conclusion, the animal welfare environment could influence the metabolomic properties of Ross breast meat and Cobb thigh meat, which may affect the sensory quality of meat.

Their breast and thigh meat were used as samples. The proximate composition, pH, color, water-holding capacity (WHC), shear force, collagen content, and fatty acid composition were determined.
