Golgin subfamily B member 1 (GOLGB1) gene encodes the coat protein 1 vesicle inhibiting factor, giantin. Previous study showed that mutations of the GOLGB1 gene are associated with dozens of human developmental disorders and diseases. However, the biological function of GOLGB1 gene in chicken is still unclear. In this study, we detected a novel 65-bp insertion/deletion (indel) polymorphism in the chicken GOLGB1 intron 5. Association of this indel with chicken growth and carcass traits was analyzed in a yellow chicken population. Results showed that this 65-bp indel was significantly associated with chicken body weight (p < 0.05), highly significantly associated with neck weight, abdominal fat weight, abdominal fat percentage and the yellow index b of breast (p < 0.01). Analysis of genetic parameters indicated that “I” was the predominant allele. Except for the yellow index b of breast, II genotype individuals had the best growth characteristics, by comparison with the ID genotype and DD genotype individuals. Moreover, the mRNA expression of GOLGB1 was detected in the liver tissue of chicken with different GOLGB1 genotypes, where the DD genotype displayed high expression levels. These findings hinted that the 65-bp indel in GOLGB1 could be assigned to a molecular marker in chicken breeding and enhance production in the chicken industry.

The objective was to explore the possible impacts of dietary supplementation with a synbiotic, organic acids or their combination on the growing efficiency, carcass traits and some blood constituents in broilers. In total, 160 1-day-old male broilers (Ross 308) were randomly assigned into four equal groups (40 birds with 8 replicates). The control group received the basal diet with no supplements, while diets of the treated groups were supplemented with organic acids (OA; 1 g/kg), a synbiotic (S; 1 g/kg) and an equal mix of OA and the synbiotic (OS; 2 g/kg). The dietary supplementation with OA decreased the feed intake (P = 0.011) and bodyweight gain (P = 0.011) when compared with other experimental groups. However, the dietary supplementation with the synbiotic plus OA resulted in a considerable improvement in the overall feed conversion rate when compared with the control and OA-supplemented groups (P = 0.001). Groups fed the diets supplemented with the synbiotic or the synbiotic plus OA showed significantly higher net profits and the profit to cost ratio than did the CON and OA-supplemented groups (P = 0.010 and 0.005 respectively). Birds in the S and OS groups had a significantly higher jejunum villus height (P = 0.001), and carcass (P = 0.012) and breast meat (P = 0.001) yields than did those in the control and OA groups. However, the synbiotic-supplemented group produced significantly lower abdominal fat percentage (P = 0.021). The dietary supplementation with the synbiotic or the synbiotic plus OA decreased the lymphocyte counts (P = 0.003) and the serum reduced glutathione concentration (P = 0.001), but significantly decreased the heterophil to lymphocyte ratio (P = 0.001), and the serum cholesterol (P = 0.014) and oxidised glutathione (P = 0.002) concentrations compared with the control and OA-supplemented groups. The present findings showed that dietary supplementation with a synbiotic or a synbiotic plus OA can improve the growth performance, carcass traits, serum antioxidant activity and blood-related indices in broilers.

Objective: The purpose of this study was i) to identify the characteristics of carcass traits in Chikso by gender, region, age at slaughter, and coat color using the carcass data collected from the nationwide pedigree information and coat color investigation, and ii) to estimate genetic parameters for breed improvement.Methods: A linear model was used to analyze the environmental effects on the carcass traits and to estimate genetic parameters. Analysis of variance was performed using TYPE III sum of squares for the unbalanced data provided by the general linear model procedure. Variance components for genetic parameters was estimated using REMLF90 of the BLUPF90 family programs.Results: Phenotypic performance of carcass weight (CW), eye muscle area (EMA), and backfat thickness (BF) in Chikso were lower than those of Hanwoo. This is a natural outcome because Hanwoo have undergone significant efforts for improvement at the national level, a phenomenon not observed in Chikso. Another factor influencing the above outcome was the smaller population size of Chikso compared to that of Hanwoo’s. The heritabilities of CW, EMA, BF, and marbling score in Chikso were estimated as 0.50, 0.37, 0.35, and 0.53, respectively, which were was higher than those of Hanwoo.Conclusion: Based on the genetic parameters that were estimated in this study, it is expected that the carcass traits will improve when the livestock research institutes at each province conduct small-scale performance tests and the semen is provided to farmers after selecting proven bulls using the state-of-art selection technique such as genomic selection.
