Selenium(Se) is an essential trace element in the human body. Main function of this element is a catalytic part of antioxidant enzymes that protect cells against the attacks of free radicals that are produced during normal metabolism of the body. Se is also essential for normal function of the immune system and thyroid gland. It also appears to be a key nutrient in counteracting the development of virulence and inhibiting HIV(human immunodeficiency virus) progression to AIDS. It is also required for sperm motility and reduces the depression. Therefore, it is very meaningful that livestock producers generate Se-fortified animal products, such as Se-egg, Se-milk, Se-pork, Se-chicken and Se-beef from the point of producers as well as human heath. However, regulation on Se usage and Se-fortified food/feed is far from being clear in Korea even though Se should be carefully monitored because of its toxicity. Thus, one has to be aware of Se properties when designing Se-fortified animal products.

Buffalo meat patties with two fat levels, F1 (15% added fat) and F2 (5% added fat and 3% tapioca starch), were cooked in a pre-heated hot air oven (HO) at $175{\pm}2^{\circ}C$ for 15 min, in a microwave oven (MO) for 70 sec and by pressure cooking (PC) at 15 psi pressure for 10 min. and compared for physico-chemical, processing, sensory and microbiological quality attributes. F2 had significantly (p<0.05) higher value for the moisture and moisture protein ratio than F1. However, MO and PC patties had significantly (p<0.05) higher moisture content than HO-cooked buffalo meat patties irrespective of fat content. Highest fat percentage was in MO patties while the minimum was in PC patties. Moisture and fat retention and cooking yield were highest in MO patties irrespective of added fat content in the formulation. Cooking yield and dimensional parameters were better maintained in F2 than F1. Sensory scores viz. appearance and color, flavour, juiciness and texture for HO patties were better than other cooking methods. Sensory panelists rated overall acceptability of HO patties very good to excellent, whereas PC and MO patties were rated as good to very good irrespective of fat content. Microbiological quality was comparable in both groups irrespective of cooking methods used.

The in-vitro meat is a novel concept in food biotechnology comprising field of tissue engineering and cellular agriculture. It involves production of edible biomass by in-vitro culture of stem cells harvested from the muscle of live animals by self-organizing or scaffolding methodology. It is considered as efficient, environmental friendly, better ensuring public safety and nutritional security, as well as ethical way of producing meat. Source of stem cells, media ingredients, supply of large size bioreactors, skilled manpower, sanitary requirements, production of products with similar sensory and textural attributes as of conventional meat, consumer acceptance, and proper set up of regulatory framework are challenges faced in commercialization and consumer acceptance of in-vitro meat. To realize any perceivable change in various socio-economic and environmental spheres, the technology should be commercialized and should be cost-effective as conventional meat and widely accepted among consumers. The new challenges of increasing demand of meat with the increasing population could be fulfill by the establishment of in-vitro meat production at large scale and its popularization. The adoption of in-vitro meat production at an industrial scale will lead to self-sufficiency in the developed world.

The objective of this study was to establish a multi-residue quantitative method for the analysis of anthelmintic and antiprotozoal drugs in various livestock products (beef, pork, and chicken) using ultra-high-performance liquid chromatography-tandem mass spectrometry. Each compound performed validation at three different levels i.e., 0.5, 1, and 2× the maximum residue limit according to the CODEX guidelines (CAC/GL 71-2009). This study was conducted according to the modified quick, easy, cheap, effective, rugged, and safe procedure. The matrix-matched calibrations gave correlation coefficients >0.98, and the obtained recoveries were in the range of 60.2%-119.9%, with coefficients of variation ≤32.0%. Furthermore, the detection and quantification limits of the method were in the ranges of 0.03-3.2 and 0.1-9.7 ㎍/kg, respectively. Moreover, a survey of residual anthelmintic and antiprotozoal drugs was also carried out in 30 samples of beef, pork, and chicken collected in Korea. Toltrazuril sulfone was detected in all three samples. Thus, our results indicated that the developed method is suitable for determining the anthelmintic and antiprotozoal drug contents in livestock products.

The objective of this study was to investigate the incidence of PSE pork depending on different stunning conditions at slaughterhouse. The carcass weights were significantly lower in the normal pork(74.6 kg) than those in the severe PSE pork(76.9 kg) and light PSE pork(77.0 kg). The groups of PSE pork showing the light or the severe PSE sign had significantly lower backfat thickness and intramuscular fat contents when compared to the normal pork(p < 0.05). The incidences of PSE pork significantly increased with the increase of the electrical stunning voltages such that they were 12.3% with 220V of stunning voltage, 17.41% with 240 V of stunning voltage, 24.91 % with 250 V of stunning voltage and 43.12 % with 430 V of stunning voltage. On the other hand, the incidence of PSE pork was significantly lower in $CO_2$ stunning(33 %) than high-voltage stunning(500 V, 72.96 %) when they were slaughtered with the same slaughtering condition except the stunning method. The $CO_2$ stunning method was very effective to reduce the incidence of PSE pork. Therefore, the result from this study suggested that the stunning methods had a significant effect on the incidence of PSE pork. Also, the low-voltage stunning and $CO_2$ stunning methods were highly recommended to control and maintain the pork quality.

A survey was performed to analyse the current animal disease control system by questionnaires. A questionnaire was administered to the livestock-related experts(n = 116) residing in Gyeong-In region and the livestock farmers(n = 108) residing in Incheon from June to July in 2007. The data was analyzed statistically by SPSS 12.0 version. First, the offices related to the animal disease control were dispersed and their cooperation was not effective. Second, the scale of local disease centers was weaker than that of central one in both man-power(eg. veterinarians), budget and so on, and was not enough to control the outbreak of the main animal diseases. Third, there were also insufficient incentives for livestock farmers to report notifiable animal disease. Finally, there was limitation in bury area and incineration facilities. To develop domestic animal industry, control of the disease and rearing of the environmentally friendly livestock farm are the main directions in Gyeong-In region, Production of high quality and safe livestock products is the most important factor to expand the livestock industry. Conclusively, local animal disease center with comparison to central one should be expanded to control the disease and develop the livestock industry in Incheon metropolitan city.

Objective: Low fat duck meat sausages were prepared by replacing the fat in the formulations with soy protein isolate (SPI) and inulin to find the best formulation having superior shelf-life without affecting its quality attributes. Methods: Four sausage mix formulations were prepared viz.control (0% SPI and inulin), T₁ (2.5% inulin), T₂ (2.5% SPI), and T₃ (2.5% SPI+2.5% inulin) replacing duck fat as per the recipe. Five batches of duck meat sausages of each formulation were prepared, and the final products were evaluated for physico-chemical, organoleptic, and microbiological qualities. Results: The % moisture and crude protein content of the sausages revealed an increasing trend (p<0.01) from control to the treated formulations, while the % total ash contents were found to be non-significant (p>0.05). On the contrary, the per cent ether extract decreased significantly (p<0.01) from the control to the treated groups. In terms of calorie value, control samples exhibited the highest values with a significant (p<0.01) regression from control to treated formulation, respectively. The colour profile study (L, a^*, b^*) of the formulations were found to be non-significant. Texture profile study in terms of springiness, cohesiveness, chewiness, and resilience revealed no significant difference in all the treatment groups except the hardness scores, which revealed a significantly (p<0.01) increasing trend from control to the treated formulations. The total viable count showed a significant decrease in the treated groups. However, there was a significant increase in the bacterial load during the storage till day 15th. The total viable psychrophilic bacterial count showed a significant (p<0.01) increase in bacterial load from day 5th to 15th day of storage. Colititre counts were negative for all the formulations until the 15th day of storage. Conclusion: The present study results may conclude that duck meat sausages could be prepared satisfactorily by replacing duck fat with SPI and inulin at the rate of 2.5% of each with superior quality attributes.
