To evaluate the effects of n-3 and n-9 fatty acid combination on broiler chicks, diets containing the combinations of five different fat sources including flaxseed oil, fish oil, EPA, DHA and olive oil were provided, and all chicks were processed at 4 weeks of growth. Liver, breast and thigh samples were collected and fatty acid composition and/or CIE
measurement were measured. Also, live chick and liver weights were weighed and the ratio was provided as an evidence of fat accumulation in liver. No significant difference was determined in both live and liver weight ratio and liver color. EPA was low in FHO as compared to livers from others. In contrast, DHA was significantly high in FHO. In broiler breasts derived from FDO, AA and n-3 fatty acid content was high, but only numerical differences of EPA and DHA were determined in breasts from FDO. The thighs from FHO showed high in EPA, DHA and n-3 fatty acid content but had low in AA and n-6 to n-3 ratio. Therefore, the results indicate that broiler chicken diets containing either FDO or FHO may be possible combination diets increasing n-3 polyunsaturated fatty acids in broiler chicks.

The aim of this study was to investigate phenotypic characteristics, morphometric measurements, reproduction and production performances of Aseel chicken of Bangladesh. The dominant feather color of neck/hackles was red in both males (56.14%) and females (54.16%) while the sickle feather color was mostly black in both chickens (71.93% vs. 54.17%). The predominant saddle and breast feather colors were red (40.35%) and black (64.91%), respectively, in male whereas most frequent observed color was pale brown in female (58.33 and 50.0%, respectively). The predominant feather color of wing bow and wing bay was found black (68.42 and 80.70%, respectively) in male but only pale brown color was observed in females (62.5 and 54.17%, respectively) for these two characters. Different phenotypic measurements such as the average shank length and circumference were
cm, respectively, in male and
cm, respectively, in female. Keel length was
cm in male and
cm in female. The average adult live weight in male was measured
g while in female it was
g. The age of 1st lay was found to be 28.86 weeks. Total number of eggs laid per year ranged between 24~48, number of clutch/hen/year varied from 2 to 4 and number of eggs/clutch/hen was found to be 10~12. The average live weight of Aseel chicken at 1, 2, 3, 4, 6, 8, 10, 12, 16 and 17 weeks of age were recorded as
g respectively. Finally, this phenotypic characterization as well as productive and reproductive performances of Aseel chicken will give the baseline information to researcher for further study and for planning any on-ward conservation and implement strategy.

Coccidiosis control programs such as vaccines or in-feed anticoccidials are commonly practiced in the poultry industry to improve growth performance and health of commercial broiler chickens. In this study, we assessed the effects of various coccidiosis control programs (e.g., in ovo vaccination, synthetic chemicals, and antibiotic ionophores) on immune status of broiler chickens vaccinated against infectious bronchitis virus and Newcastle disease virus (ND) and raised on an Eimeria-contaminated used litter. In general, the levels of
-1-acid glycoprotein, an acute phase protein, were altered by the treatments when measured at 34 days of age. Splenocyte subpopulations and serum antibody titers against ND were altered by various coccidiosis control programs. In-ovo-vaccinated chickens exhibited highest mitogenic response when their spleen cells were stimulated with concanavalin A (Con A) at 7 days of age. It is clear from this study that the type of coccidiosis control program influenced various aspects of innate and adaptive immune parameters of broiler chickens. Further studies will be necessary to delineate the underlying relationship between the type of coccidiosis control program and host immune system and to understand the role of other external environmental factors such as gut microbiota on host-pathogen interaction in various disease control programs.

This experiment was conducted to investigate the dietary effects of turmeric powder (TP) on laying performances, egg qualities and its transfer into eggs. A total of two hundred, 60-wk-old, Lohmann Brown layers were divided into 4 groups, placed in to 5 replicates per group (10 layers each) and fed each one of four diets containing 0% TP (control), 0.10, 0.25 or 0.50% TP, respectively, for 7 wks. Egg production in the all groups fed diets containing TP were significantly higher than that in control (P<0.05). No differences in feed intakes, egg and eggshell qualities were observed among the treatments, but Roche color fan number (yolk color) in group fed diet with 0.5% TP was significantly higher than in control (P<0.05). In the groups fed diets containing TP, Haugh units after 2 wk of storage were significantly higher than that of control (P<0.05). The curcumin content of egg yolk in the groups fed diet containing 0.50% TP was significantly higher than those in the other groups (P<0.05). The cholesterol levels of egg yolk were not influenced by dietary TP. It was concluded that dietary TP was effective in improving laying performance and internal egg qualities. TP can be also used as a feed additive for the production of value-enhanced eggs with increased yolk color and curcumin content.

One of the biggest challenges for the animal feed industry in the coming years will be to meet the growing demand in animal protein in light of increased cost of feed ingredient as well as tougher restrictions on the use of antimicrobial growth promoters imposed by consumers and governments. A key focus area will be to maximise feed efficiency and minimise nutrient waste. It has been widely acknowledged that the composition of the intestinal microflora is closely related to intestinal health and performance of animals. Advanced microbial techniques have shown a close relationship between bacterial communities and their ability to modulate nutrient absorption and processing. In addition it has been recognised that modulating the immune response has significant impact on overall health as well as overall nutrient demand. Molecular techniques are a useful tool to gain an understanding of the impact of dietary interventions including the use of functional feed additives on specific changes in microbial communities or the immune system. Most these techniques however focus on the evaluation of large changes in bacterial compositions and often underestimate or neglect to recognise small changes in microbial diversity or behaviour changes without any measurable immune response. The key to understanding the relationship between specific nutritional intervention and the impact on health and performance lies in a deeper understanding of the impact of these nutrients on the expression of specific genes or specific metabolic pathways. The development of molecular tools as a result of developments in the field of Nutrigenomics has enabled researchers to study the effects of specific nutrients on the whole genome or in other words, the effect of thousands of genes simultaneously, and has opened a completely different avenue for nutritional research.

This study was conducted to investigate the effect of dietary supplementation levels of spinach powder and extract on performance, egg quality and lutein content in egg yolk. Laying hens were subjected to one of the following treatments; C, basal diet (BD); T1, BD + 1 ppm lutein from spinach powder; T2, BD + 1 ppm lutein powder from spinach extract; T3, BD + 2 ppm lutein powder from spinach extract; T4, BD + 2 ppm lutein from spinach extract. As a result, performance of laying hens was no significant difference among treatments. T4 had a significantly (p<0.05) higher egg yolk color than the other treatments. As from the lutein content in egg yolk, T4 had a significantly (p<0.05) higher content than the other treatments. Finally, these results suggested that the dietary supplementation for lutein-rich egg production, lutein concentration must be higher than a minimum of 2 ppm. Also, dietary with lutein extract from raw materials was appropriate for lutein-rich egg production than dietary with raw materials.

This study was carried out to investigate the growth performance and the carcass ratio of meat-type Korean Native Ducks. Four hundred twenty Korean Native Ducks` chicks were selected and divided into four treatments (7 replications/ treatment, 15 birds/replication) by strains (A and B) and gender(male and female) with
fractal factors. There was no significant difference between A and B on the body weight at 2, 4, 6, and 8 weeks old (P>0.05). However, body weight of female was higher at 2 weeks old than male while that of male was higher at the 8 weeks old (P<0.01). Daily feed intake of male was higher compared to female during 6~8 weeks (P<0.05). On weekly body weight gain, there was no significant difference between strains, but gained body weight of male was higher until 2 weeks old while that of female was higher during 6~8 weeks (P<0.01). On the live body weight and carcass weight by strains and genders, B strain was higher than A strains at the 8 weeks of age (P<0.01). Carcass yield was the highest at 8 weeks of age in both strains (P<0.05). These results may provided the basic data on growth performance and carcass ratio of meat-type Korean Native Ducks.
Advances and Future Directions in Poultry Nutrition: An Overview
Ravindran, Velmurugu ;

In the past, poultry nutrition has focussed on increasing the production efficiency to meet the progress achieved in the genetic potential of broilers and layers. Future directions in poultry nutrition will be driven by not only by the need to maximise biological and economic performance of birds, but also by societal issues (environment, antibiotic growth promoters, welfare, traceability and use of genetically modified ingredients). Key advances in poultry nutrition are discussed and future directions, which can be expected, are highlighted. Given the tightening supply and ever-increasing cost of raw materials, there will be more pressure to extract every unit of energy and nutrients from feed ingredients. In this context, a number of feed additives are expected to play an increasingly significant role. Feed enzymes and crystalline amino acids, in particular, will have a profound effect on future sustainability of the poultry industry. Future nutritional research need to focus on identifying the barriers to effective digestion and utilisation of nutrients and, to achieve this objective, nutritionists must combine their expertise with those of specialising in other biological sciences, including immunology, microbiology, histology and molecular biology.

DOI : 10.5536/KJPS.2012.39.1.063
This study was conducted to determine the possible use of Red Ginseng marc as stress inhibiter in thermal stress (temperature humidity index 86) and lipopolysaccharide (LPS) - exposed laying hens by investigating their effects on laying performance, blood biochemical parameters, immunoglobulin concentration and serum superoxide dismutase (SOD) like ability. A total of forty-five 52-wk-old laying hens (ISA Brown) were divided into 3 treatment groups with 5 replicates of 3 birds in each group. NC (negative control, no immune substances), PC (positive control,
-glucan 25 ppm) and RGM (Red Ginseng Marc 3%) were added in feed with respective substance. Egg production in RGM was significantly increased in comparison with NC groups for 8 weeks (P<0.05). On blood biochemical parameters, effects of ambient temperature is definite by showing significant difference in aspartate aminotransferase and others (P<0.05), but RGM both before and after thermal stimulation have no significant difference in comparison with other groups. And for 3 weeks after thermal stimulation, laying performance was also not significantly different among treatments. Immunoglobulin M content and SOD like activities after challenge with LPS were higher in the RGM and PC than NC (P<0.05). In conclusion, although ineffective as inhibiter in thermal stress, dietary supplementation of Red Ginseng marc improved SOD like activity and immune system by regulating immunoglobulin content in laying hens. These findings have laid the foundation for future studies of immunomodulation in laying hens fed Red Ginseng Marc and of evaluation of heat stress inhibitor.

This study was carried out to investigate the performance of growing period of two-crossbred of Korean Native Chickens. A total of four hundred eighty female 2-crossbred chicks that restored strains and were aboriginal at National Institute of Animal Science. Treatments were four crossbreds (4 replications/crossbred, 30 birds/replication) as A) C strain
S strain, B) C strain
H strain, C) R strain
S strain, and D) L strain
H strain, respectively. Livability of C crossbred was the highest as over 90% and that of B crossbred was the lowest as 73~78% during growing period (P<0.05). Body weight of A crossbred was the highest at the 4 week and that of D strain was the lowest at the 4 and 8 week (P<0.05). Weekly body weight of B and C crossbreds were higher than A and D crossbreds (P<0.05). There was no significant difference among four crossbreds. Weekly feed intake of D crossbred was the highest among all crossbreds at 0~4 weeks (P<0.05). These results suggested the basic data on the record of growing phase of 2-crossbreed Korean Native Chickens.
