The present study investigated the optimum additive ratio of wheat straw pellet as a substitute for beet pulp during oyster mushroom cultivation. The chemical properties across treatments were pH of 4.8–5.5, total carbon content of 45.9–46.5%, total nitrogen content of 1.5–1.7%, and carbon-to-nitrogen ratio of 27.8–31.0. Mycelial growth was the fastest in a medium containing 20% wheat straw pellet (at 88.2 mm in ‘Heuktari’ and 70.3–79.6 mm in ‘Suhan-1Ho’); however, there were no significant differences in mycelial density among the treatments. The characteristics of fruiting bodies by variety were as follows. In ‘Heuktari’, the valid stipe number per bottle (1,100 cc) was 22.5 and yield was 177.1 g/1,100 cc in the mixed medium containing 10% wheat straw pellet, with the values being comparable to those of controls. In ‘Suhan-1Ho’, the valid stipe number per bottle (1,100 cc) was 14.0 and yield was 151.2 g/1,100 cc in the mixed medium containing 10% wheat straw pellet, with the values being comparable to those of controls.

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.

느타리버섯 병재배용 재료중 비트펄프를 대체하기 위해열매탈과팜이삭(PEFB)를 6, 8mm 형태의 펠렛으로 성형한 후 첨가비율을 달리하여 5개의 처리구로 나누어 느타리버섯을 재배한 결과는 다음과 같았다. 수한1호의 경우,T1 78.8g, T2 90.6g, T3 76.0g, T4 88.6g, T5 55.4g으로 대조구인 T1보다 T2, T4처리구에서 수량이 많았다.춘추계통의 김제5호의 경우, T1 111.6g, T2 139.8g, T3133.47g, T4 126.8g, T5 136.2g으로 T2, T5처리구에서수량이 많았다. 위 시험결과를 종합해볼 때, 열매탈과팜이삭(PEFB)를 비트펄프로 대체하여 느타리버섯 재배에 이용이 가능함을 확인할 수 있었다.
