Objective: This study was conducted to evaluate various levels of milk by-product in weaning pig diet on growth performance, blood profiles, carcass characteristics and economic performance for weaning to finishing pigs. Methods: A total of 160 weaning pigs ([Yorkshire${\times}$Landrace]${\times}$Duroc), average $7.01{\pm}1.32kg$ body weight (BW), were allotted to four treatments by BW and sex in 10 replications with 4 pigs per pen in a randomized complete block design. Pigs were fed each treatment diet with various levels of milk by-product (Phase 1: 0%, 10%, 20%, and 30%, Phase 2: 0%, 5%, 10%, and 15%, respectively). During weaning period (0 to 5 week), weaning pigs were fed experimental diets and all pigs were fed the same commercial feed during growing-finishing period (6 to 14 week). Results: In the growth trial, BW, average daily gain (ADG), and average daily feed intake (ADFI) in the nursery period (5 weeks) increased as the milk by-product level in the diet increased (linear, p<0.05). Linear increases of pig BW with increasing the milk product levels were observed until late growing period (linear, p = 0.01). However, there were no significant differences in BW at the finishing periods, ADG, ADFI, and gain:feed ratio during the entire growing-finishing periods. The blood urea nitrogen concentration had no significant difference among dietary treatments. High inclusion level of milk by-product in weaner diet decreased crude protein (quadratic, p = 0.05) and crude ash (Linear, p = 0.05) of Longissimus muscle. In addition, cooking loss and water holding capacity increased with increasing milk product levels in the weaner diets (linear, p<0.01; p = 0.05). High milk by-product treatment had higher feed cost per weight gain compared to non-milk by-products treatment (linear, p = 0.01). Conclusion: Supplementation of 10% to 5% milk by-products in weaning pig diet had results equivalent to the 30% to 15% milk treatment and 0% milk by-product supplementation in the diet had no negative influence on growth performance of finishing pigs.

이 논문은 소매업체의 청과물 구입실태와 농산물 도매시장 구매의 문제점을 조사 분석하여 소매업체와 도매시장간 연계성 강화 방안을 모색하고 있다. 대형유통업체는 구매채널이 비교적 골고루 분산되어 효율적인 구매방식을 모색하고 있으나 중소 유통업체는 산지직거래 능력이 미약하여 주로 중도매인(방문구매)에 의존하고 있다. 업태별로 향후 도매시장 구입 의향을 보면, 대형유통업체와 외식/급식업체의 경우 도매시장 구입을 유지 내지 감축하려는 비율이 높고, 중소유통업체는 도매시장 구입을 확대 내지 유지하려는 경향을 보였다. 소매업체가 도매시장 구입 시 느끼는 문제점으로는 상품의 균질성 미흡과 속박이, 저온저장고 부족, 장소협소로 물류미비, 유통비용과다, 가격안정성 미흡 등이 있다. 농산물 도매시장이 시급히 개선해야 할 사항으로는 시장면적 확대로 물류효율화, 저온저장고 확충 등 시설 개선, 품질관리시스템 확립, 소분 포장 등 가공시설 확충 등인 것으로 조사되었다. 소매업체와 농산물 도매시장간 연계를 강화시키기 위해서는 도매시장 공간 확보를 통한 물류 원활화, 도매시장내 국가 검품제도 도입, 경락가격 안정화 방안 모색, 하역비 절감 방안, 소매업태별 차별화 마케팅 추진, 중도매인의 규모화 등이 필요하다. 거래제도 측면에서는 단기적으로 선취매매, 정가수의매매 등을 활성화시키고 중장기적으로는 도매상제도의 확대가 필요하다.

Sample preparation including dehydration and drying of samples is the most intricate part of scanning electron microscopy. Most current sample preparation protocols use critical-point drying with liquid carbon dioxide. Very few studies have reported samples that were dried using chemical reagents. In this study, we used hexamethyldisilazane, a chemical drying reagent, to prepare plant samples. As glandular trichomes are among the most fragile and sensitive surface structures found on plants, we used Millingtonia hortensis leaf samples as our study materials because they contain abundant glandular trichomes. The results obtained using this new method are identical to those produced via critical-point drying.

We developed a type of sausage made of chicken breast and liquid egg whites for consumers interested in weight management. To determine the quality of the product, its chemical characteristics, fatty acid composition, free amino acid contents, and nucleotides contents were evaluated during 4 weeks of storage. Sensory evaluation was conducted by both general consumers and body-builders. The sausage was proposed as a fat-free product as fat content was 0.12% based on the Korean Indication Standard of Animal Origin Food. Protein content was 13.42% and calorie value was 61.50 kcal/100 g of the sausage. In sensory evaluation, the mixture of chicken breast and egg whites stuffed into the same casing had an adverse effect on taste, color, texture and overall acceptance while the product that contained egg white stuffed separately into the outer casing enclosing the chicken breast (double layer) improved these attributes. The developed double-layer sausage can last for at least 4 weeks of storage without quality deterioration of flavor-related compounds, such as fatty acids and nucleotides.
