This study was performed to discover bifidobacteria isolated from human intestines that optimally convert linoleic acid (LA) conjugated (CLA) and optimize the culture conditions of milk fermentation. One hundred fifty neonatal were screened for CLA-producing ability, Bifidobacterium breve LMC 017 selected as it showed about 90% conversion free LA in MRS broth. The strain resistance at 0.5% microaerophillic conditions. When monolinolein (LA 90%) used a substrate CLA production, rate lower...
This study was performed to characterize natural CLnA isomer production by Bifidobacterium breve LMC520 of human origin in comparison conjugated linoleic acid (CLA) production. B. found be highly active terms production, which the major portion identified as cis-9,trans-11,cis-15 GC-MS and NMR analysis. incubated for 48 h using MRS medium (containing 0.05% l-cysteine·HCl) under different environmental conditions such atmosphere, pH, substrate concentration. The high conversion rate...
In this study, the effects of four dietary supplementation levels rice bran (RB) on milk yield and composition were examined in Saanen dairy goats. Four goats (initial bodyweight, 55.0 ± 7.1 kg) 21-day periods used a 4 × Latin-square design. The diets contained 0, 5, 10, 20% DM RB, but otherwise formulated to be 10.7 MJ metabolisable energy/kg 18.8% crude protein/kg DM. Goats consumed greatest amount feed concentrate when fed 5% RB diet (P < 0.01); however, forage intake was not...
본 연구는 거세한우 비육시 섬유질배합사료의 급여가 발육, 사료이용성 및 도체특성에 미치는 효과를 구명하고, 기존의 분리급여 방법과의 경제성을 비교검토코자 실시하였다. 생후 약 6개월령(평균체중 153kg 내외)의 거세 한우 60두를 공시하였으며, 사양시험은 6개월령부터 28개월령까지 22개월간 시험설계는 배합사료와 볏짚 분리급여구(Control), 습식 섬유질배합사료 급여구(TMRⅠ), 맥강 20%(TMRⅡ) 40%(TMRⅢ) 함유 건식 급여구 등 4처리로 하여 각 처리당 15두씩 완전 임의배치하였다. 일당증체량은 20%를 첨가한 섬유질배합사료구가 0.70kg으로 모든 처리구에서 가장 높았으나 처리간에 유의적인 차이는 없었다(p>0.05). 전기간 kg 증체당 사료요구량은 대조구가 11.63kg 이었고, 급여구인 TMRⅠ, TMRⅡ TMRⅢ구는 각각 9.29, 10.46 10.71kg 이었다. 도체율과 거래정육율은 처리구가 59% 63% 내외로 처리간 차이가 없었으며(p>...
This study was conducted to determine the effects of dietary multi-nutritional targeted supplementation according different growth stages on performance, blood metabolites and carcass characteristics Korean native Hanwoo steers.Thirty two steers, 6 months age weighing 159.2±24.1 kg, were distributed into 2 groups: control group without any supplements, (MNTS) treatment supplied with wheat bran catechins (WBC, 8 16 age), ruminally protected amino acid-enriched fatty acid (RPAFA, 17 28 age)...
본 연구는 한국의 충남과 전북지역에서 생산되는 유기우유와 일반우유의 이화학적 성분분석을 통해 차이점을 구명하고자 수행하였으며, 각 지역에서 유기우유 및 일반우유 생산농가를 각각 5개씩 선정하여 3회(2월, 3월 8월) 우유를 채취하였으며, 일반성분, 무기물 지방산을 분석하였다. 유기우유의 유성분 중 유지방(p<0.01), 총 고형물(p<0.05), 유리지방산(p<0.01) 구연산(p<0.05)의 함량은 일반우유에 비해 유의적으로 낮았지만, 유단백질은 높았다(p<0.05). 유당, 우유 요소태 질소(MUN) 체세포수는 일반우유와 차이가 없었지만, MUN은 전북지역의 우유가 충남지역보다 우유내 P의 함량만 유기우유에서 높았고(p<0.01), Ca, K, Mg, Zn Fe의 없었다. 지방산 분석 결과, 함량이 높은 palmitic acid나 oleic acid에서는 유의적 stearic acid와 포화지방산은 일반우유에서 높았다(p<0.01). 또한, 불포화지방산인...
Vitamin C (VC) supplements have been used for enhancing marbling fat in high-quality beef cattle. However, mode of action VC was not clearly studied a long time. The aim this experiment to determine the effect dose titration bovine muscle-derived cells (MDC) from semimembranosus (SM) and longissimus dorsi (LD) muscle tissues. We hypothesized that may affect adipogenesis MDC isolated different depots. Bovine were pronase liberated SM LD tissues 3 newborn Hanwoo calves. incubated with...
α-solanine is a glycoalkaloid compound found in leaves, fruit and tubers of potato. poisoning was reported various animal models such as mice, rabbit, chicken. However, previous study indicated a-solanine to induce performance beef cattle. We hypothesized that may affect myogenesis bovine satellite cells but not adipogenesis adipocytes. Bovine (BSC) were pronase-liberated from semimembranosus (SM) muscle tissues three new-born Hanwoo calves. preadipocytes isolated perirenal (PR),...
