This study was conducted to investigate effect of feeding beet pulp on reproductive performance, colostrum composition and microbiological characteristics in sows. A total of 12 sows(Landrace×Yorkshire) were randomly allotted three dietary treatments at gestating 90 days. The diets were prepared by adding 0, 5 and 10% of the beet pulp in basal diets. The pigs fed 5% beet pulp showed higher litter size than the 0 and 10% beet pulp treatments, although there was not significant among the treatments. Similarly, birth and 21days weight in piglet were not different among the treatments. In colostrum fat, protein, lactose, citric acid, solid, ffa, true protein were ranged to reference values, but not difference among the treatments. E.coli of feces was lower(P<0.01) in the 5% beet pulp than the 0 and 10% beet pulp treatments. But no effect was observed on Lactobacilli of feces among dietary treatments. These our results indicate the beet pulp has no significant effect of reproductive performance and colostrum composition in sows. But, 5% level beet pulp is effective for reduction of intestinal pathogenic microorganisms.

Background : Curcuma longa L., is a very famous spice and medicinal herb in several countries of the world. Curcumin and volatile oils of C. longa improve hepatic and renal functions, and could be used against biliary disorders, diabetic and hepatic disorders. This medicinal plant was introduced for the regional promotion, Jeollanam-do, as the subtropic area in Korea. In the present study, the plant was introduced to the Jeollanam-do region of Korea with the aim to determine the optimal planting densities for growth characteristics, yield and curcumin contents which have not been reported up until now. Methods and Results : The field experiment was conducted at the experimental farm of Division of Traditional Korean Medicine Resource, NIKOM, Jangheung-gun, Jeollanam-do, Korea. The seedstock was planted at 40×20cm, 40×30cm and 40×40cm spacing with 3 replications. Nine plants were selected randomly for observations on growth characteristics such as plant height, stem diameter, leaves number, leaves area and to dry weight at days after transplanting (DAT) 90, 120 and 150. The dried samples of plant were stored in air tight polythene bags at room temperature for HPLC analysis of curcumin, which was undertaken following standard procedures. Top plant growth was observed in the 40×30cm planting density of C. longa, plant height, leaves number, leaves area and day shoot weight were larger than in the other treatments. Root length, root diameter and supporting roots of underground part were increased as planting density was wide, and dry root weight was increased in 40×30cm. However, yield and curcumin constituent was highest each 294 kg/10a and 68.7 mg/g in the planting density of 40×20cm. Conclusion : Based on the results of this study, planting density of 40×20cm is the most suitable in the cultivation and curcumin constituents of C. longa.
