iNOS (Inducible nitric oxide synthase) and TLR-4 (Toll-like Receptor-4) play crucial roles in innate immunity of poultry. iNOS has been mapped to chicken chromosome 14 and implicated in a variety of chicken diseases. iNOS possesses potent antimicrobial activity, including the inhibition of microbes replication in vitro. TLR-4 is a pathogen associated molecular-pattern receptor for bacterial product, such as LPS (lipopolysaccharides) found in Gram negative bacteria, that triggers pro-inflammatory cytokine expression after engagement with ligands. In the previous studies, genetic analysis of iNOS and TLR-4 revealed the possible association of mutation in these genes with the intestinal microflora of cecum when infected with Salmonella spp. This study was aimed to augment previous findings, which show the association of iNOS (C14513T) and TLR-4 (G4409T) polymorphisms with economic traits in Korean Native Black (KNB), Rhode Island Red (RIR) and Cornish chickens. Investigation in the effect of SNPs on economic traits (layday, layw, layno, bw150, bw270, layw270) was conducted. iNOS (C14513T) had a significant effect on the average body weight at 270 days of age (p<0.05) in both KNB and RIR, whereas TLR-4 (G4409T) showed no significant correlation with all traits (p>0.05). The results obtained from using the candidate genes can be useful for the genetic improvement of body weight in both KNB and RIR breeds.

FABPs, 15 kDa organic substances, are small intracellular proteins which have a primary role to regulate fatty acid uptake and intracellular transport. This study was conducted to identify SNPs in the two FABP family genes and their associations with the body weight traits in Korean native chicken (KNC). Two SNPs, namely g.508C>T of FABP3 gene and g.285C>T of FABP4 gene, have been genotyped by using PCR-RFLP method. The results showed that FABP3 was significantly associated with body weight at birth, body weights at 12 to 20 weeks, and also slaughter weight. Moreover, the g.285C>T SNP of FABP4 gene was not associated with any body weight traits. These results suggested that the g.508C>T SNP of FABP3 genes can be used as molecular markers to select KNC having desirable body weights.

The present study examined effects of production performance, immune activity and egg quality by raising on exercise yard in laying Hens, the results of which could be used as baseline data to enhance animal welfare and the safety of livestock products. A total of 90 Hy-line-Brown laying hens of 13 weeks old were used in the experiment for 38 weeks. The cage group (Cage group) was raised in a cage, where an area of
was assigned to two hens, while hens in the exercise yard
group) was assigned to a combination of a chicken house (
) and a exercise yard (
) per a hen. Hens in the exercise yard
group) was assigned to a combination of a chicken house (
) and a exercise yard (
) per a hen. Treatment was replicated 3 times with ten birds per replication. Ten birds were arranged according to randomized block design. While initial egg production rate was significantly higher in the Cage group,
group exhibited a slightly higher rate in the mid- and late-stage of the experiment, although the difference was not statistically significant. Exercise yard treatment groups exhibited a higher feed intake rate than the Cage group up until the hens were 39 weeks old (P<0.05), but the difference dissipated from that age on. The age at first egg in the exercise yard treatment groups was 16 days later than that for the Cage group (P<0.05), although differences in the quality of the eggs were not observed. The results of immune activity test showed that IgA in the exercise yard treatment groups was significantly higher than that in the Cage group (P<0.05). IgG, IgM, and corticosterone were also higher in the exercise yard treatment groups. The soil in exercise yard increased of organic matter and decreased of cation exchange capacity (CEC) in raised hens. In sum, raising hens in a exercise yard raise style decreased the rate of initial egg production, which was followed by a slight increase during the latter part of the experiment. The exercise yard raise hens' immune activity was heightened.

The present study was performed to assess the worth of using the by products for seaweed (Eucheuma spinosum) ethanol production process (SEPPB) as broiler feeds. For this purpose, 225 broiler chicks (white mini broilers) were used as experimental animals. The control (Control group) was fed with the broiler feeds. 5% mixture (5% SEPPB group) was fed with a 5% SEPPB mixture feeds, and the 10% mixture (10% SEPPB group) was fed with a 10% SEPPB group mixture feeds. The experiment was repeated for five times and 15 birds were assigned in each experiment and the experimental period was five weeks. There was no difference in the rate of weight gain until the second week of the 5% SEPPB group and 10% SEPPB group. However, the weight gain rate was increased to 6.2% for the 5% SEPPB group and 11.4% for the 10% SEPPB group as compared to the Control group at the third weeks of the experimental period. There was no statistical significant difference in terms of feed FCR and feed intake. Analyses of the quality of chicken breasts showed that pH was 2.5% higher in the 5% SEPPB group and 2.3% higher in the 10% SEPPB group. Shearing force was 31.3% lower in the 5% SEPPB group and 14.7% lower in the 10% SEPPB group, while heating loss was 14.4% lower for 5% SEPPB group and 10% SEPPB group when compared to the Control group. No significant differences were observed in terms of moisture, protein, and crude ash components in chicken breast analyses. However, crude fat was 36.8% higher in the 5% SEPPB group when compared to the Control group (P<0.05). Analyses of fatty acid in chicken breast meat showed that stearic acid was significantly higher in the 10% SEPPB group (P<0.05) and linolenic acid was significantly higher in 5% SEPPB group and 10% SEPPB group in comparison to the Control group (P<0.05). Interleukin-2 (IL-2) in blood serum was 44% higher in the 5% SEPPB group and 36% higher in the 10% SEPPB group (P<0.05). Interleukin-6 (IL-6) was similar in both the Control and the 5% SEPPB group, but it was 62% higher in the 10% SEPPB group in comparison to the Control group (P<0.05). Analyses of serum chemical values revealed that albumin was the highest in the 5% SEPPB group, followed by the Control group and then 10% SEPPB group.

Thyroid hormone (TH) plays a role in growth of the poultry. Thyroid-stimulating hormone (TSH) stimulates production and distribution of TH, and is a heterodimer which is formed by
-subunits. Most of TSH activity is known to rely on
gene is located on chicken chromosome 26 and associated with growth performances. Therefore, this study aimed to investigate the association of TSH-
SNP (G1031C) with economic traits (layday, layw, layno, bw150, bw270, layw270) in Korean Native Black chicken, Rhode Island Red and Cornish. Allele frequency of GG genotype in Rhode Island Red (RIR) was found to be 1.00 in this study. A significant effect was only observed on body weight at day 150 in Cornish. In Cornish, body weights of chicken with the CC genotype (
) were significantly higher than that of the GG genotype (
) (p<0.05). These findings suggest that the G1031C SNP of TSH-
gene can be used for improvement of growth-related traits in Cornish.

This work was carried to evaluate production efficiency factor, carcass yield and meat quality with weeks of Large-type Korean native ducks. Korean native ducks (n = 90) from National Institute of Animal Science (RDA, Korea) were used in this work. Ninety ducks were divided into 6 groups (15 birds/group) and were fed with meat-type duck diets for 8 wk old. When ducks grew at specific wk (6, 7 and 8 weeks), 2 ducks per group were slaughtered at 6, 7 and 8 wk old. Production efficiency factor, carcass yield, partial meat and meat quality were researched in this work. There was no significant difference on livability with weeks, but body weight at 7 and 8 wk old was higher than that at 6 wk old (P<0.05). Feed conversion ratio at 6, 7 and 8 wk old were 2.25, 2.69 and 3.21, respectively, so there was significant difference with weeks (P<0.05). Production efficiency factor at 6, 7 and 8 wk old were 256.6, 199.8 and 153.0, respectively, so there was significant difference with weeks (P<0.05). Carcass yield at 8 wk old was higher than that at 6 and 7 wk old as 73.5% (P<0.05). Lightness at 6, 7 and 8 wk were 41.8, 39.0 and 38.1, respectively, and that at 6 wk old was the higher than other weeks (P<0.05). There was no significant difference on redness at 6, 7, and 8 wk old (P>0.05) and yellowness at 8 wk old was higher compared to other weeks (P<0.05). Cooking loss was the highest at 6 wk old as 31.6%, but water holding capacity was the highest at 8 wk old (P<0.05). There was no significant difference on shear force among weeks. pH at 6 wk old was the lower than that of other weeks as 5.84. Moisture content significantly decreased with weeks (P<0.05) and fat content at 8 wk was the highest as 1.88% (P<0.05). Protein content significantly increased with weeks until 20.9% at the age of 8 wk (P<0.05). Ash content at 7 and 8 wk old was the higher than that at 6 wk old (P<0.05). There was no significant difference on juiciness, tenderness, and flavor with weeks. Finally, these results may provide that shipping time at 7 wk old preferred to that at 6 and 7 wk old, but further research was needed because of deficiency of data.

An experiment was conducted to determine the effects of origins of soybean meal (SBM) on growth performance, nutrients and energy retention and fecal microflora in broilers. The SBM originating from Korea, Brazil and India were used. A total of 480 broiler chicks (average initial BW, 41.8 g) were randomly allotted to 6 treatments. Each treatment had 4 replicate pens with 20 chicks per pen. Birds were fed diets containing SBM originated from Korea (domestic SBM), Brazil or India (imported SBM) and the diets were based on the total amino acid (TAA) or true digestible amino acid (TDAA). Experimental diets were fed in two phases, starter (d 0~21) and finisher (d 22~35). The overall weight gain, feed intake and FCR were better (P<0.05) in birds fed Korean SBM. During starter and finisher periods, birds fed diets containing Korean SBM had greater (P<0.05) retention of GE, DM, and CP (P<0.05) as compared with Birds fed diets containing SBM from India. In addition, diets formulated on TDAA basis had grater (P<0.05) CP retention during starter period and DM, GE and CP retention during finisher period. There were no differences (P>0.05) in the excreta microflora and overall feed cost per kg body weight gain in birds fed SBM from different origins; however, diets formulated on TDAA basis had lesser (P<0.05) feed cost per kg body weight gain in birds when compared with diets formulated on TAA basis. These results indicate that Korean SBM has better nutrients digestibility than SMB originated from Brazil and India, which contributes to the improved performance of broilers. In addition, better performance was obtained when diets were formulated on TIDAA basis.

There are several loci controlling the feather color of birds, of which one of the most studied is Extended black (E) encoding the melanocortin 1-receptor (MC1R). Mutations in this gene affect the relative distribution of eumelanin, phaeomelanin. The association of feather color and sequence polymorphism in the melanocortin 1-receptor (MC1R) gene was investigated using Korean native chicken H breed (H_PL) and 'Woorimatdag' commercial chickens (Woorimatdag_CC). In order to correlate gene mutation to Korean native chicken feather color, single nucleotide polymorphism (SNP) from MC1R gene sequence were investigated. A total of 307 birds from H_PL and Woorimatdag_CC were used. H_PL have black, black-brown feather color and Woorimatdag_CC have black with brown spots or brown with black spots. There are 6 SNPs in MC1R gene, locus T69C, C212T, A274G, G376A, G636A, T637C. 3 SNPs are nonsynonymous that change amino acid. But it is difficult to find correlation of feather color and polymorphisms. It will be needed to increase the population of Korean native chicken H breed and correlation analysis of genetic variation with feather colors.

This study was conducted to evaluate the effects of dietary supplementation of vitamin C or E on the expressions of endoplasmic reticulum (ER) stress, lipid and glucose metabolism associated genes in broiler chickens. A total of 216 one-day-old male broilers was randomly alloted to 4 treatments with 6 replicate pens per treatment and 9 broilers per pen for 35 days. The dietary treatments were control, vitamin C (control diet + ascorbic acid 200 mg/kg diet), vitamin E (control diet +
-tocopherol 100 mg/kg diet), vitamin C + E (control diet + vitamin C 200 mg/kg + vitamin E 100 mg/kg), respectively. To evaluate gene expressions by quantitative real-time polymerase chain reaction, total RNA was extracted from the liver of the chicken at 35 days of age. Dietary supplementation of vitamins was significantly down-regulated the expression of stress marker genes including HSP70, HSP90, and HMGCR, as compared to the control (p<0.05). The expressions of ER stress associated genes also inhibited by supplementation of vitamins as well (p<0.05). Vitamin C supplementation suppressed the expression of lipid associated genes such as FASN, FATP1 and ACSL1. Vitamin supplementation did not affect the glucose transporters, GLUT2 and GLUT8, in the liver. The results of the present study indicated that dietary supplementation of vitamin C or E could be beneficial for the alleviating physiological stress in broiler chickens.

Both ODC and PRDM16 genes were known to be associated with body weight traits in chicken. These two genes were located on GGA3 and GGA21, respectively, where the QTLs of body weights are located. Therefore, the objectives of this study were to identify the SNPs in these two genes and their associations with body weight traits in Korean native chicken. Fluidigm Dynamic Array integrated fluidic circuits (IFCs) assay was used to genotype 7 SNPs consisting g.-353C>T, g.2136A>G, g.2524T>C, g.3607C>T SNPs of the ODC gene, and g.182216C>T, g.182290A>T, g.182491A>T SNPs of the PRDM16 gene. Statistical analysis showed that g.2136A>G SNP of the ODC was associated with body weight at 20 weeks of age and slaughter weight, and g.3607C>T SNP of the ODC was associated with body weight at 2 weeks of age. Association between g.182216C>T SNP of the PRDM16 and body weight at 12 weeks of age has also been revealed. In addition, g.182491A>T SNP of PRDM16 has significant correlation with body weight (BW) at 8 weeks, BW at 10 weeks and BW at 14 weeks of age. These results suggested that both ODC and PRDM16 could be strong candidate genes for body weight traits in Korean native chicken.
