영어

Domestic SAMs (super activated material series) were added by 0.8% to the feed of 24 pigs in order to study the component change of excretion, the reduction effect of malodorous substances, and the change of meatiness. P, Zn, Mn, and organic components out of excrement components were decreased. Valeraldehyde, a highly malodorous substance, and methyl isobutyl ketone were decreased by 58% and 39%, respectively. As for the characteristics of meatiness, in the group with addition of 0.8% SAMs, all of the brightness, red index, and yellow index tended to increase in comparison with those of control group. As for the dressed carcass, the effect of 0.8% SAMs addition on the growth (weight increase and feed conversion rate) was insignificant. The concentration of immunoglobulin G in the blood of growing piglets was increased from the range of 25 to 50% in the 11th week to the range of 40 to 60% in the 16th week, and the number of lymphocytes started to increase from the 5th week and increased by 18% in the 16th week. There existed preventive effects on respiratory disease and viral syndrome, which often generate in growing pigs. The results above indicate that the addition of SAMs to pig feeds is expected to decrease the amount of such an environmental pollutant excretion as P out of excrement and to have a positive influence on the immunity enhancement and growth rate.

국내산 초활성점토광물 SAMs (super activated material series)를 양돈사료에 0.8% 첨가하여 24마리의 돼지를 사육하면서 배설물의 성분 변화, 악취물질의 감소효과와 육질의 변화와 혈액성상의 변화를 연구하는 것이 목적이었다. 배설분(排泄糞) 성분 중에서 P, Zn, Mn과 유기성분등이 감소하는 효과가 있었다. 악취강도가 높은 성분인 valeraldehyde 는 58%, methyl isobutyl ketone은 39%의 감소효과를 보였다. 육질의 특성은 SAMs 0.8% 첨가구의 경우 대조구 에 비해 전체적으로 명도와 적색도, 황색도 모두 증가하는 경향을 나타내었다. 도체(屠體)성적은 양돈 사료에 SAMs를 0.8% 첨가한 결과 발육(증체 및 사료 요구율)에는 유의성은 없었다. 육성기 돼지새끼에서 혈중 면역항체G의 농도가 11주에서 25-50%, 16주에서 40-60% 수준으로 증가하였고, 임파구의 수는 11주부터 증가하기 시작하여, 16주에는 18% 증가하였다. 이상의 결과로 볼 때 양돈 사료에 SAMs의 첨가는 분(糞) 중 P와 같은 환경오염물질 배설량의 감소 가 기대되며, 일부 높은 악취성 물질의 감소와 면역증진과 성장률에 긍정적으로 영향을 미칠 것으로 기대된다.
