Two experiments were conducted to determine the effects of supplementing different levels of kaolin (Exp. 1) and effects of age of layers and levels of kaolin (Exp. 2) on the performance, egg and shell quality parameters of laying hens. In Exp.1, 64 laying hens of 58 wks age were randomly allotted to 4 treatments of 16 hens in each. Dietary treatments were basal diet supplemented with 0.0, 0.2, 0.4 and 0.6% kaolin. In Exp. 2 96 laying hens were divided into 6 groups of 16 hens each in a 2 ${\times}$ 3 factorial arrangement (two different ages, 30 and 58 wk and three levels of kaolin, 0.0, 0.2 and 0.4%). In both the experiment there were linear decreases in feed intake (P<0.001), improvement in FCR (P<0.05), and egg production (P<0.05), with increasing dietary kolin level. Supplementation of kaolin had no effect on the egg and shell quality parameters in both experiments. Thus, it is concluded that kaolin may improve performance, and 0.2% level showed the best laying performance.

This study was carried out to evaluate the visual turfgrass's color quality, winter color, and spring green-up under three different soil systems and to make a practical use for sports turf design and construction. Several turfgrasses were evaluated in multi-layer, USGA and mono-layer systems. Turfgrass entries in the study comprised of 3 cultivars from Korean lawngrass (Zoysia japonica Steud.) of typical warm-season grass (WSG) and 3 blends and 3 mixtures from Kentucky bluegrass (KB, Poa pratensis L.), perennial ryegrass (PR, Lolium perenne L.), and tall fescue (TF, Festuca arundinacea Schreb.) of cool-season grass (CSG). Significant differences were observed in the turfgrass's color quality, winter color, and spring green-up in the study. Seasonal variation of visual turf color greatly occurred according to soil systems and turfgrasses. Multi-layer and USGA systems were highly associated with better visual color ratings, as compared with mono-layer system. Regardless of soil system, visual turf color in all entries was better from spring to fall than in winter. Great color differences were observed during a period of early December to early spring. CSG produced a better color quality over WSG in any soil system. Overall color ratings for CSG were KB > PR > Mixtures > TF. As for a winter color, its ranking was USGA > multi-layer > mono-layer system. No difference was found in winter among cultivars of Korean lawngrass, being completely brown, but great differences among CSG. Rated best for winter color was PR, followed by CSG mixtures, KB and finally TF in order. It was generally conceded that fast green-up in spring was greatly related with multi-layer over mono-layer system and also CSG over WSG. Among CSG, TF had a fastest green-up. PR was also fast in green-up, but poor in color uniformity. KB, however, was the slowest due to shallow rooting system, when compared with other CSGs. These results demonstrate color differences were greatly variable according to soil systems and also among turfgrass species. A precise decision should be made in selecting turfgrass species and soil system. Multi-layer and USGA systems were considered as the suitable one for turfgrass color quality, winter color and spring green-up. It is a great necessity to combine proper soil system, right turfgrass species, and appropriate mixing rates by a concept-oriented approach, when establishing garden, parks, soccer field, and golf courses and so on.

We investigated the effects of organic acid and ultrasonication treatment in maintaining the quality of garlic during storage. Samples were exposed for 5 min to either ultrasonication at 60℃, 1% citric acid, or 0.5% fumaric acid. Presence of microorganisms and minerals, hardness, and color were compared during storage at 4℃ for 28 days. The total aerobic bacterial count remained low. No proliferation of Escherichia coli was observed after treatment with fumaric acid or ultrasonication, and mold proliferation was inhibited by ultrasonication. The mineral content of the northern type garlic was higher than that of the southern type. Exposure to fumaric acid did not result in a substantial difference in hardness until 21 days of storage, at which time there was a decrease in the L-value in each cultivation type. Our results indicate that treatment with 0.5% fumaric acid for 5 min was effective in reducing the abundance of microorganisms during storage without affecting the hardness or color in garlic.

본 연구는 산란계의 주령 및 난강의 이상 및 이상 정도가 내부품질에 미치는 영향을 조사하기 위해 실시되었다. 정상란과 이상란은 각각 81.22%, 18.78%의 출현율을 보였다. 난백높이와 호우유닛은 이상란이 낮고 또한 이상의 정도가 심한 경우 더 낮게 측정되는 결과를 보였다(p < 0.05). 특히 이상란 중에서도 기형란의 내부품질에 미치는 영향이 가장 큰 것으로 나타났다. 결과를 종합해 보면 계란의 외형적 이상은 내부품질의 저하와 밀접하게 상관한다고 볼 수 있다.

The current experiment was conducted to evaluate the effects of adding Salicornia extract to the drinking water on the performance, egg quality, and blood profile of laying hens. A total of 216 Hy-Line Brown laying hens at 40 weeks of age were used in a 10-week experiment. The birds were allotted into three experimental treatments with three replications per treatment and 24 birds per replication. The treatments were CON (basal diet), T1 (1 cc of Salicornia extract per liter of drinking water), and T2 (5 cc of Salicornia extract per liter of drinking water). The collected data were analyzed using the SAS package program. The results indicated that addition of Salicornia extract to the drinking water of laying hens did not cause any negative effects on the performance, egg quality, or blood profile. Compared to the control treatment, the treatments with Salicornia extract remarkably increased egg production (P<0.05) in the last week of the study, improved egg shell thickness and significantly reduced the egg breaking rate (P<0.05). The results of this study showed that the addition of Salicornia extract improved egg shell quality; thus, Salicornia extract can decrease the egg breaking rate and increase production on commercial farms.

Two experiments were conducted to evaluate the feeding values of sesame oil meal (SOM) and to investigate the effects of its dietary supplementation on egg production in laying hens. In experiment I, the values of true metabolizable energy (TME), nitrogen corrected true metabolizable energy (TMEn) and true amino acid availability (TAAA) were determined by force-feeding 16 ISA-Brown roosters and collecting the total excreta from the birds, The TME and TMEn of SOM were 2.30 and 1.99 kcal/g, respectively, and the average TAAA of 15 amino acids was $76.93\%$. In experiment 2, a total of ninety, 48 weeks old ISA-Brown layer were randomly divided into 9 groups of 10 birds each and assigned to three experimental diets containing 0, 5 and $10\%$ SOM for 4 weeks (30 birds per treatment). The inclusion of SOM into laying hen diets at the 5 and $10\%$ level did not affect production and quality of egg. The C18:3 $\omega$3 content of egg yolks in the $10\%$ SOM group was higher than the other groups, but not significantly. There were no adverse effects on blood parameters in layers fed treated diets containing $5\%$ or $10\%$ SOM, The results indicate that SOM can be used for layers diet up to $10\%$ without any significant negative effects on egg production and quality.
