The objective of this study is to investigate individual animal variation bovine fecal microbiota including as affected by diets. Fecal samples were collected from 426 cattle fed 1 3 diets typically feedlot cattle: 1) 143 steers finishing diet (83% dry-rolled corn, 13% corn silage, and 4% supplement), 2) 147 late growing (66% 26% 8% 3) 136 heifers early (70% silage 30% alfalfa haylage). Bacterial 16S rRNA gene amplicons determined using next-generation pyrosequencing technology. A total...
The objective of this study was to determine the effect lysozyme and antibiotics on zoonotic pathogen shedding in faeces from nursery pigs housed without with an indirect disease challenge.Two replicates approximately 650 each were weaned randomly assigned one 24 pens either a room that had been fully disinfected or left unclean. Pigs control diet (Control), + (Antibiotic; chlortetracycline tiamulin), (Lysozyme; 100 mg kg(-1) diet). Rectal swab samples collected day 0 28 treatment, enriched...
Methane (CH4) gas released by cattle is a product of fermentation in the digestive tract. The 2 primary sites CH4 production ruminants are reticulum-rumen complex and cecum. release from represents 2% to 12% loss energy intake. Reducing proportion feed lost as has potential improving efficiency well decreasing contribution greenhouse production. Feed intake growth were measured on 132 fall-born steers for 70 d. Seven with extreme positive residual gain (RG) 7 negative RG whose DMI was within...
The objective of this study was to determine if the faecal microbiome has an association with Escherichia coli O157:H7 prevalence and enumeration. Pyrosequencing analysis performed from feedlot cattle fed one three diets: (i) 94 heifers low concentrate (LC) diet, (ii) 142 steers moderate (MC) (iii) 132 high (HC) diet. A total 322 585 OTUs were calculated 2,411,122 high‐quality sequences obtained 368 samples. In LC diet group, assigned orders Clostridiales RF39 (placed within class...
The objective of the study was to determine levels Escherichia coli O157:H7 colonization in gastrointestinal tract (GIT) naturally shedding cattle pathogen at low- or super-shedder levels.Over 2 years, feedlot were sampled multiple times for faecal E. O157:H7. Just prior harvest (1-2 days), animals that super-shedders (≥104 CFU per gram faeces) specifically identified, and based on longer term screening data, pen cohorts low-shedders (years 1 2) chronic-shedders (year 1) also identified. At...
Here, the effect of microwave-dried black soldier fly ( Hermetia illucens ) larvae meal (HILM) as a dietary protein source on growth performance and health broilers was evaluated. A total 126 male were randomly allocated to three treatments (six replicates seven birds per group): control diet (CON) corn soybean two experimental diets in which replaced with 25% (25HILM) or 50% (50HILM) HILM. The slaughtered at 35 d determine apparent ileal digestibility (AID), volatile fatty acid (VFA)...
서언 갓(Leaf mustard: Brassica juncea)은 배추과에 속하는 채소류 중 하나로 우의 삼각형(U's triangle)에 따르면 배추(AA, 2n=20)와 흑 갓(BB, 2n=16)의 복이배체(amphidiploid, AABB, 2n=36)종으로 알려져 있으며(Yang et al. 2016), 국내에서 는 여수 지역에서 많이 재배되어 오고 있다.갓의 독특한 맛은 글루코시놀레이트(glucosinolate, GSL)의 일종인 sinigrin이 가수분해되어 나오는 allyl iso-thiocyanate (AITC)에 기인한다.이로 인해 갓은 독특하면서도 톡 쏘는 맛을 가지게 된다(Dai 2014).갓 가공식품인 갓김치는 칼륨 등 무기질 영양이 풍부하여 지역특산물로서 발전하고 있기 때문에 농업적으로 우수한 형질을 가지는 다양한 용도의 갓을 개발하는 것은 중요하다.
Tulip cultivation in Korea primarily uses imported bulbs due to the absence of domestic production. To ensure safety and sustainability, Korean authorities have implemented strict phytosanitary measures for five viruses: arabis mosaic virus, tobacco necrosis ringspot tomato black ring bushy stunt virus. In April 2021, 86 tulip plants presented symptoms such as chlorotic mottle, mosaic, streak, stripe, yellowing leaves, color breaking on flowers. These samples were collected investigate...
