This study were carried to investigate to the effects of diet supplemented with pine needle powder on pH, total phenol contents, DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity, TBARS (thiobarbituric acid reactive substance), WHC (water holding capacity), shear force, sensory evaluation, meat color, and fatty acid composition of chicken meat. Broiler chicks were fed the corresponding diets containing 0% pine needle powder (Control), 0.3% pine needle powder (T1), 0.6% pine needle powder (T2), or 0.9% pine needle powder (T3) for five weeks. The pH and TBARS was significantly decreased by the supplementation of pine needle powder compared to the control (P<0.05). The total phenol contents and DPPH radical scavenging activity were significantly increased by the supplementation of pine needle powder compared to the control (P<0.05), and T3 showed the most effective (P<0.05) more effective in improving self-life compared to the other treatment groups. The CIE
value of treatment groups showed significantly higher value compare to the control, however, CIE
values was decreased. In fatty acid composition, the level of oleic acid in chicken meat was significantly (P<0.05) increased by the supplementation of pine needle powder compared with the control group. In conclusion, dietary supplementation of pine needle powder was effective in decreasing pH and TBARS, and increasing total phenol contents and DPPH radical scavenging activity in broiler meats.

DOI : 10.5536/KJPS.2011.38.4.255
This work was conducted to investigate the effects of phytase on the growth performance, excreta excretion, and N and P excretion of broilers for 7 weeks. One hundred ninety two Ross broiler (one-day-old) with average weight
g were assigned randomly to 4 treatments groups (12 birds/pen, 4 pens/treatment) as
complex factors of sex of broiler male, female) and phytase 2 treatments (0, 300 FTU/kg), and fed experimental diets for 6 weeks (starter, 0~2 wk; earlier, 2~4 wk; finisher, 4~7 wk). The experimental diets included that phytase was added to the basal diet. Body weight was high at male treatment and at phytase treatment. Feed intake was high at male treatment and was no difference between phytase and non-phytase treatment. Feed efficiency was the highest at male and phytase treatment. Manure excretion was high at male treatment and reduced at phytase treatment. Excretion of N and P was high at male treatment and at non-phytase treatment. Finally, when phyase was added to basal diet, the growth performance of broilers was improved and excreta excretion and N and P excretion of broilers were decreased.

DOI : 10.5536/KJPS.2011.38.4.265
This study was carried out to determine the effect of dietary supplementation of quercetin and methoxylated quercetin extracted from onions on chicken thigh meat quality during cold storage. For 35 days, 1-day-old 320 broiler chicks (Ross) were divided into 8 groups and supplemented the diet; basal diet only (CONTROL), CONTROL with antibiotics (AB), vitamin E 20 IU (VE20), vitamin E 200 IU (VE200), quercetin 20 ppm (QC20), quercetin 200 ppm (QC200), methoxylated quercetin 20 ppm (MQ20), and methoxylated quercetin 200 ppm (MQ200). After slaughtering the broilers, thighs were separated and analyzed the quality change of the meat during storage at
for 7 days. The meat quality factors such as pH, color, water holding capacity, and sensory characteristics of thigh meat were determined on the experiment day 0, 3, and 7. After slaughtering, the pH of AB, VE 20, QC 20, and MQ 200 showed no significant difference compare to that of CONTROL. However, VE 200 and QC 20 showed higher pH value than CONTROL on storage day 3.
value of chicken thigh of MQ 20 was lower than CONTROL on storage day 0, however, no significant difference was found between CONTROL and treatments on storage day 3. Redness (
) of chicken thigh in CONTROL was increased during storage. QC 20, QC 200, and MQ 200 significantly reduced the
value of chicken thigh (p<0.05). Water holding capacity of VE 20 and MQ 200 was significantly higher than the CONTROL on the day 0. Also, QC 200 showed higher WHC compare to the CONTROL. In sensory evaluation, overall acceptability of chicken thigh in quercetin and methoxylated quercetin group showed no significant differences compare to that of CONTROL by storage day 3. These results suggested that the quercetin and methoxylated quercetin could be used as additives to enhance broiler thigh meat quality such as pH and WHC without adverse effect on color and sensory characteristics.

As the world population grows and developing countries become more affluent, the global consumption of meat will increase by more than 50% within the next 10 years. Confronting the increased demand for poultry food products are emerging field diseases, increasing regulatory bans of antimicrobial growth promoters, high-density growth conditions, and waste management. Although biotechnology offers solutions to some of these challenges, basic studies are needed to better understand the complex interaction between the intestinal microbiome, host immunity and the environment. This presentation will focus on emerging strategies to enhance gut immunity and to decrease economic losses due to poultry diseases. This presentation will highlight recent developments in coccidiosis research and provide information on host immunity, immunomodulation, and the latest advances in dietary and nutritional approaches against coccidiosis. Such information will magnify our understanding of host-parasite biology, mucosal immunology, and design of future nutritional interventions and vaccination strategies for coccidiosis.

This study was conducted to investigate the effect of different raising days (30, 36, 42) on physico-chemical meat quality properties of chicken breasts and legs stard with 1 day old. In chemical compositions, moisture and protein contents (%) were decreased whereas fat contents (%) were increased as the raising days. In mineral contents, there was not significantly different in calcium contents. However, there was a decrease of potassium contents (p<0.05) as raising periods increased. Nucleotide-related compounds were 121.0 mg/100 g at 30 day, 130.4 at 36 day and 131.2 at 42 day, respectively. However, they were not significantly different during the raising periods (p<0.05). The similar tendency was observed in leg parts.
values were decreased especially for chicken raised for 42 days.
values were gradually increased as the raising periods increased. Cooking loss (%) was decreased whereas Warner-Bratzler shear forces (WBS) were increased as the raising periods increased.

DOI : 10.5536/KJPS.2011.38.4.293
The current work was carried out to investigate the effect of crossbred Korean native chickens (KNC) on performance and meat quality. A total of 720 chicks (1d of age) was used in this work and were divided into groups by crossbreds (A, B, C and D) and sex (male and female). Crossbreds were A) (KNC egg-meat type C strains
KNC meat type S strains)
Ross broiler, B) (KNC egg-meat type C strains
KNC meat type H strains)
KNC meat type S strains, C) (KNC native R strains
KNC meat type S strains)
KNC meat type H strains and D(White Semibroiler Chickens). Experimental diets consisted of 3 phases such as starter (0~5 weeks; CP 20.0%, ME 3,050 kcal/kg), earlier (5~8 weeks; CP 18.0%, ME 3,100 kcal/kg) and finisher (8~12 weeks; CP 16.0%, ME 3,150 kcal/kg). They were fed the broiler diets for 12 weeks at the flat house and thirty six chickens were slaughtered at week 5 and 10. There was no significant difference on the fertility of crossbred KNCs, and the hatchability of B crossbred was low compared to other crossbreds. On body weight (BW), D crossbred resulted in a higher BW after 5 weeks (P<0.05). Body weight gain (BWG) and feed intake (FI) of A crossbred were also significant higher compared to the other crossbreds for all periods. On carcass ratio (CR), A crossbred showed higher CR at 5 weeks, there was no significant among crossbreds at 10 weeks. The partial meat ratio(ala, breast, neck, leg) of C crossbred was the lowest among other crossbreds (P<0.05), but the back meat ratio was not difference among treatments at 5 and 10 weeks. pH of meats have no difference among crossbreds at 5 week, and A crossbred was high compared to other crossbreds at 10 week (P<0.05). The moisture content of D crossbred meat and the protein content of B crossbred meat were high compared to other crossbreds at 5 week. Chemical compositions of meats have no difference among crossbreds at 10 week. Lightness and redness have not significance among crossbreds at 5 week, and redness of A crossbred was the highest among all crossbreds (P<0.05). Shear force and cooking loss of A crossbred were high at 5 week, and cooking loss of A crossbred was low compared with other crossbreds at 10 week. These results suggested the basic data that needed to develope the new strains.

DOI : 10.5536/KJPS.2011.38.4.305
This study was conducted to investigate the effects of housing systems on the productivity and physiological response as stress indicators in White Leghorn chickens. The chickens subjected to the conventional cages had a significantly lower viability, hen-housed egg production, egg weight and body weight compared with those to the floor pens. However, the hens housed in the conventional cages had a shorter day of the first egg and a greater egg quality compared with those housed in the floor pens. In addition, this study was also investigated to identify biological markers for assessing the physiological response of chickens under stress conditions. As biological markers, the amount of telomeric DNA was analyzed by quantitative fluorescent in situ hybridization on the nuclei of cells. The DNA damage rate of lymphocytes was also quantified by the comet assay. The amount of telomeric DNA of the lymphocytes, kidney and spleen was significantly higher in the chickens under floor pens than those under conventional cages. The DNA damage also increased in chickens raised under conventional cages, as compared to the chickens under floor pens. As results, we conclude that the chickens housed in conventional cages have a greater stressful status than those housed in floor pens.

This study was carried out to determine the effect of dietary supplementation of resveratrol and methoxylated resveratrol extracted from branch of Morus alba L. on the quality of chicken thigh meat during cold storage. For 35 days, 1-day-old 320 broiler chicks (Ross) were divided into 8 groups and supplemented the diet; basal diet only (BD), BD with antibiotics (AB), vitamin E 20 IU (VE 20), vitamin E 200 IU (VE 200), resveratrol 20 ppm (RV 20), resveratrol 200 ppm (RV 200), methoxylated resveratrol 20 ppm (MR 20), and methoxylated resveratrol 200 ppm (MR 200). After slaughtering the broilers, thighs were collected and analyzed the quality change of the meat during storage at
for 5 days. The meat quality factors such as pH, color, water holding capacity, and sensory characteristics of thigh meat were determined on the experiment day 1, 3, and 5. AB, VE, and MR increased pH value of chicken thigh compare to BD (p<0.05). Lightness (
) showed no significant difference during storage day 1 and 5. VE 200 and MR 20 stabilized the redness (
) of chicken thigh as the value of day 1. Water holding capacity of chicken thigh from VE 20, RV 200, MR 20, and MR 200 on storage day 3 was higher than that of BD (p<0.05). In sensory evaluation, the panelist discriminated the tenderness and gave the higher score on the chicken from AB, VE20, RV 20, and MR 20 compare to BD (p<0.05). These results suggest that the dietary resveratrol and methoxylated resveratrol could be used as chicken meat quality enhancer in broiler industry.

The chicken monoclonal antibody (mAb), 13C8, reacts with sporozoite antigens of Eimeria spp. which causes avian coccidiosis. Since this mAb was produced at low amount due to genetic instability of chicken hybridoma, a recombinant 13C8 single-chain Fv (ScFv) antibody was constructed by amplification of the variable domain of heavy (VH) and light chain (VL) genes of antibody derived from chicken hybridoma. The constructed 13C8 ScFv was successfully expressed in E. coli and purified as a soluble form. In ELISA analysis, this recombinant 13C8 ScFv antibody showed antigen binding activity as the original mAb. In addition, nucleotide sequence comparison of 13C8 gene to the germline chicken VL and VH genes suggested that the gene conversion with
and VH pseudogenes might contribute to the diversification of VL and VH genes in chickens.

DOI : 10.5536/KJPS.2011.38.4.331
The study was conducted to evaluate the production and the performance test of egg-type commercial Korean Native Chickens. A total of 360 female layers were produced from CY
C (A), CL
C (B), CG
C (C) and CW
C (D) crossbreds kept at National Institute of Animal Science, Korea, and breed during 20~64 weeks to investigate the productivity and the performance. Layers were divided into 4 crossbreds (6 replications/crossbred, 15 heads/replication). Age and egg weight at first egg was no significantly different among crossbreds. Body weight (BW) at first egg of D crossbred was significantly lower compared to that of other crossbreds (P<0.05). Weekly BW of B crossbred was the highest at 20, 30 and 40 weeks of age, but BW of D crossbred was the lowest among crossbreds. Feed intake (FI) of B crossbred was significantly higher compared to the other crossbreds at 20~24, 32~44 and 52~60 weeks of age. FI of D crossbred was significantly lower compared to other crossbreds after the age of 44 weeks (P<0.05). Average egg weight of B crossbred was significantly higher than the other crossbreds at the age of 24~60 weeks (P<0.05). Egg production ratio (%) of C crossbred was significantly higher compared to the other crossbreds for whole test periods (P<0.05). Hen-housed egg production number at 64 weeks of age for A, B, C and D crossbreds resulted in 241.4, 235.6, 232.3 and 227.0, respectively. Feed conversion ratio of A and C crossbreds was lower compared to the other crossbreds at the age of 20~24 weeks and C crossbred was the lowest among the crossbreds at the age of 60~64 weeks. These results provide the basic data which will be helpful to develope the new strains of commercial Korean Native Chickens.
