The current study was conducted to estimate the effect of dietary pyroligneous acid (PA) on performance, noxious gas emission in excreta, blood parameter and fatty acid composition of breast meat in Korean native chicken. A total of 240 one-day-old chicks were allocated to three treatments (PA; 0, 0.1, 0.2%) with five replicate of 16 each per treatment for 10 weeks. Although there was no effect on the performance, ammonia gas concentration was significantly decreased in the PA treatments compared to the control (p<0.05). Birds fed PA had higher serum total protein and high density lipoprotein-cholesterol (HDL-cholesterol) concentration but lower triglyceride content in the PA 0.2% treatment than control (p<0.05). In fatty acids composition of breast meat, myristic and stearic acid were significantly decreased, whereas oleic and linolenic acid were significantly increased in the group fed PA compared to those of the control group (p<0.05). The result of the current study indicates that dietary PA may reduce the noxious gas emission and improve lipid levels as well as increase of monounsaturated fatty acids composition of breast meat in Korean native chickens.

The applicability of electronic nose was tested to detect lipid peroxidation in chickens and to measure antioxidant effect of astaxanthin in chicken carcasses. Two sources of astaxanthin were fed to 62-wk-old spent laying hens to improve meat quality: natural astaxanthin (NA) from the red yeast, Phaffia rhodozyma, and synthetic astaxanthin (SA) from chemical synthesis. One hundred forty four ISA Brown laying hens were used in a 6-wk feeding trial. Three treatments consisted of the basal diet (control), SA (100 mg astaxanthin/kg basal diet) and NA (50 mg astaxanthin/kg basal diet). The astaxanthin levels of SA and NA were set to give a similar degree of skin pigmentation. After 6-wk feeding of astaxanthin, the skins from NA and SA were discriminated from the control by electronic nose. However, electronic nose failed to distinguish between SA and NA skins after 6-wk feeding. The astaxanthin level differences between skins of SA and NA were not remarkable during the 6-wk trial. The lipid peroxide formation in skin was significantly decreased by SA but not by NA. The antioxidation effect of SA was detected by electronic nose because SA skin was discriminated from others. NA was a better pigmentation agent than SA, but the reverse was true in antioxidation. Electronic nose is applicable for detecting astaxanthin in chicken, and meat off-flavor caused by lipid peroxidation during storage.

This study was conducted to investigate the effects of dietary supplementation of garlic by-products on performance, proximate composition, carcass characteristic, cholesterol, and blood composition of chickens. Broiler chicks were fed diets for 5 weeks with a diet 1% garlic by-product (T1), 2% garlic by-product (T2), and 5% garlic by-product (T3). There were no difference among diet in performance. In proximate composition, crude fat of chicken meat was decreased in diets by addition of garlic by-product than control, but moisture and crude ash were no significant difference. Liver weight was significantly increased (P<0.05) by the dietary supplementation with garlic by-products compared to the control diet. The total cholesterol and LDL-cholesterol of treatment groups was lower than control, and the HDL-cholesterol of treatment groups was higher than control (P<0.05). Especially, T3 was significantly (P<0.05) more effective in improving cholesterol compared to other treatment groups. In blood composition, GOT of broiler was decreased in diet by garlic by-products than control group, but GPT, triglyceride, and glucose were no significantly different. In conclusion, these data indicate that supplementation of garlic by-products (T3) were most effective in decreasing total cholesterol, LDL-cholesterol, and GOT and increasing HDL-cholesterol.

This work was carried out to improve the performance and the carcass yield of Korea native duck (KND) according to crossbreeding KND and broiler duck (BD). Two hundred forty out of crossbred ducks were divided into 4 strains and selected as 120 ducks separated by sex, respectively. Crossbred ducks were native ducks (female)
native ducks (male), native ducks (female)
broiler ducks (male), broiler ducks (female)
native ducks (male), and broiler ducks (female)
broiler ducks(male) as A, B, C and D, respectively. Broiler duck diet was fed as experimental diet for 0~3 weeks (CP 22.0%, ME 2,900 kcal/kg) and 3~8 weeks (CP 18.0%, ME 3,000 kcal/kg). Body weight of male was high compared to female, and that of B and C was high compared to A and low compared to D at 3 and 8 week (P<0.05). Body weight gain of male was high compared to female at 3~8 weeks and 0~8 weeks, and it was shown as D>C>B>A on body weight gain (P<0.05). In case of feed intake, there was no difference between male and female, and B and C were high compared to A and low compared to D (P<0.05). Male feed requirement was high at 3~8 weeks, and there was significant difference between A and B, C and between B and D. Carcass yield of 4 strains was shown as 70.1%, 70.8%, 73.1% and 71.2%, respectively. Finally, Crossbreeding of KND and BD may improve the performance and the carcass yield of KND.

A survey of transovarially transmitted diseases, including salmonellosis [(pullorum disease; PD)/(fowl typhoid; FT)], mycoplasmosis, avian infectious anemia (CIA), and fowl adenovirus infection was conducted in the breeder chickens from August to December in 2009. The numbers of flocks sampled out were: Grand Parents Stock (GPS), 45; Parents Stock (PS) 1,018, Baeksemi breeder (BSB) 54. The seroprevalence of salmonellosis (PD/FT) were 0% (GPS), 3.2% (PS), and 3% (BSB), respectively. A total of 983 chicken farms were affected with FT outbreaks between 2000 and 2008. The incidence of FT in commercial broilers, Baeksemi, commercial layers, native chickens, and broiler breeders was 44.3%, 26.2%, 15.7%, 12.6% and 1.08%, respectively. Of the affected broilers, over 90% birds were under 2 weeks of age, indicating it was possible that they were infected with S. gallinarum via vertical transmission. The sero-positive flocks against Mycoplasma gallisepticum (MG) were 71.1% (GPS), 88.7% (PS), 88.7% (BSB), while the rates of positive flocks against Mycoplasma synoviae (MS) were 86.0% (GPS), 77.0% (PS), and 98.0% (BSB). In GP and parent farms, the detection rates on specific genes of CIA virus were 19/45 (42.2%), and 169/1039 (18.0%), respectively, whereas the seroprevalence of CIA were 86.0% in GPS and 93.7% in PS flocks. In addition, positive flocks of fowl adenoviruses were 4.4% (GPS), 2.7% (PS) and 9.35% (BSB), respectively. As the results, avian mycoplasmosis and CIA have been more prevailing in chicken breeder than avian salmonellosis and fowl adenovirus infection in Korea.

Telomeres are nucleoprotein structures at the ends of chromosomes consisting of DNA sequences arranged in tandemly repeated units
. However, this hexamers can also occur at non-telomeric sites in some avians and vertbrate. This study was carried out to present the distribution of telomeric DNA sequences in Korean Native Chicken chromosomes. The fluorescence in situ hybridization technique using a telomeric DNA probe was performed to the metaphase spreads of chicken early embryonic cells. Telomeric DNA signals were detected at the ends of chromosomes including macrochromosomes and microchromosomes. In chicken, surprisingly, chromosome 1 showed very distinct interstitial telomeric DNA hybridization patterns which located two interstitial sites in the p-arm at 1p11 and 1p23, and one in the q-arm at 1q32. In chromosome number 2 and 3 also displayed interstitial telomeric signals (ITS) in the long arms at 2q24 and 3q32, respectively. The pattern of telomeric DNA distribution in Korean Native Chicken chromosomes was in agreement with a previously reported in Gallus domesticus. The relative amount of telomeric DNA sequences in each macrochromosomes ranged from 4.6% to 16.3%. Distribution of telomeric DNAs at the end of p-arm was much more than that of q-arm in almost chicken chromosomes. The distribution of ITS in chicken chromsomes implicate to tandem chromosome fusions that might have occurred during the process of karyotype evolution.

Inclusion body hepatitis-hydropericardium syndrome (IBH-HPS) is an acute viral disease usually found in broilers aged from 3 to 5 weeks and causes up to 75% mortality. Among the 12 serotypes of fowl adenovirus group 1, serotype-4 (FAdV-4) was identified as a primary agent of IBH-HPS and was usually isolated in IBH-HPS cases in Korea since 2007. To prevent these IBH-HPS outbreaks in Korea, we developed the FAdV-4 inactivated vaccine using Korean isolate (ADL070244) and evaluated the efficacy of this vaccine. For the efficacy test, 2-week-old specific-pathogen-free (SPF) chickens intramuscularly inoculated with 1 or 2 dose of inactivated vaccine were used and challenged with FAdV-4 through either intramuscular or oral route at 2 weeks after vaccination. The vaccine induced good seroconversion which was confirmed by agar gel precipitation (AGP) test. In addition, the vaccine could decrease the FAdV-4 detection rate and histological lesion severity such as lymphocyte infiltration and necrosis in the liver comparing with those of non-vaccination group. Based on the current results, the developed FAdV-4 inactivated vaccine in this study was effective in the terms of reduction of virus detection rate and histological lesions severity. However, it was difficult to confirm the efficacy of the vaccine clearly because of no mortality and clinical signs in the non-vaccinated group after challenge. Therefore, we need further study to develop a standard challenged model system which could clearly evaluate the efficacy of the vaccines for FAdV-4.

The objective of this study was to investigate the effects of addition of green tea extracts on physicochemical properties and shelf-life of seasoned chicken with soy sauce during cold storage. Treatments (C, T1 and T2) containing various levels (0, 1 and 2%, respectively) of green tea extracts were manufactured, and we investigated pH, meat color (
), volatile basic nitrogen (VBN), thiobarbituric acid reactive substances (TBARS), total plate counts, fatty acid composition and sensory scores during cold storage for 16 days. T1 and T2 have more dark color than control during storage time. VBN, TBARS and total plate count of control were significantly higher than those of T1 and T2 at the latter storage time (p<0.05). Also, VBN, TBARS and total plate count of all treatments was increased with storage time. Linoleic acid was the highest value in control which had the highest value of TBARS in day 16 (p<0.05). Aroma value of control was significantly higher in storage time except day 16 than those of T1 and T2 (p<0.05). Acceptability value of control was significantly higher than those of T1 and T2 in day 4, 8 and 12 (p<0.05).

Chicken is an important livestock as a valuable biomedical model as well as food for human, and there is a strong rationale for improving our understanding on metabolism and physiology of this organism. The first draft of chicken genome assembly was released in 2004, which enables elaboration on the linkage between genetic and metabolic traits of chicken. The objectives of this study were thus to reconstruct metabolic pathway of the chicken genome and to construct a chicken specific pathway genome database (PGDB). We developed a comprehensive genome database for chicken by integrating all the known annotations for chicken genes and proteins using a pipeline written in Perl. Based on the comprehensive genome annotations, metabolic pathways of the chicken genome were reconstructed using the PathoLogic algorithm in Pathway Tools software. We identified a total of 212 metabolic pathways, 2,709 enzymes, 71 transporters, 1,698 enzymatic reactions, 8 transport reactions, and 1,360 compounds in the current chicken genome build, Gallus_gallus-2.1. Comparative metabolic analysis with the human, mouse and cattle genomes revealed that core metabolic pathways are highly conserved in the chicken genome. It was indicated the quality of assembly and annotations of the chicken genome need to be improved and more researches are required for improving our understanding on function of genes and metabolic pathways of avian species. We conclude that the chicken PGDB is useful for studies on avian and chicken metabolism and provides a platform for comparative genomic and metabolic analysis of animal biology and biomedicine.

In the present study we report in vivo inhibitory potential of single strain of bacteriophage (
) in day-old SPF chicks experimentally infected with Salmonella enteritidis (SE). The bacteriophages prepared by feed additives and drinking water were given to chicks for 20 days starting prior 10 days before challenge with SE. Chicks were euthanized at 10 days after challenge for quantitative salmonella isolation from intestine and determination of environmental contamination level of salmonella. Bacteriophage therapy as additives in feed and drinking water resulted in significant inhibition of the SE replication in intestines of SPF chickens (P<0.05). In addition, environmental contamination by SE fecal shedding was decreased in bacteriophage-treated birds. Therefore, bacteriophage
examined in this study may be a plausible alternative to antibiotics for the reduction of salmonella infection both in poultry.

Because some zoonotic Salmonella can be transmitted to human through poultry products, threatening human public health, Salmonella infections in poultry are increasingly worldwide subject to control measures and programs. Given the fact that there are numerous opportunities for Salmonella to gain entry to extensive, integrated poultry operations including the hatching, handling, feeding, and processing facilities, the whole supply chain of poultry meat should be an object of Salmonella control programs as well as biosecurity of poultry farms. This article reviews Salmonella food poisoning caused by poultry source and critical need to control Salmonella in poultry productions, and describes practical strategies.
