Deoxynivalenol (DON), one of the most common mycotoxins, is frequently found in foods. This study investigated effects orally administered DON on blood biochemical parameters, growth performance, histology, microbial composition, and metabolism rats. After a 1-week adaptation period, 4-week-old rats were 0.9% saline (control), 1 mg/L (T1), 10 (T2), or 50 (T3) by gavage for 49 days. The DON-treated groups had significantly lower body weights than control group (p < 0.05). Blood alkaline...
Bovine fecal microbiota is important for host health and its composition can be affected by various factors, such as diet, age, species, breed, regions, environments. The objective of this study was to evaluate the impact diet gender on in Korean native Hanwoo cattle. 16S rRNA gene amplicon sequencing conducted from 44 cattle divided into four groups: (1) 11 heifers fed an oat hay plus total mixed ration (TMR) breeding (HOTB), (2) early fattening TMR (HEFT), (3) steers (SEFT), (4) late...
Rumen cannulation is a surgical technique used to collect rumen contents from ruminants. However, surgery may potentially impact the composition of microbiota. This study aimed examine longitudinal alterations in microbiota Hanwoo steers after surgery. In this study, eight were used; four underwent (cannulation group), while remaining left intact (control group). samples collected all using stomach tubing method on day before (day 0) and postoperative days 1, 4, 7, 10, 14, 17, 21, 24, 28,...
Mycotoxin-contaminated feed or food can affect physiological responses and cause illnesses in humans animals. In this study, we evaluated the effects of deoxynivalenol (DON) toxicity on growth performance, blood biochemistry, histology, microbiome, metabolism rats fed with different toxin concentrations. After 1 week acclimatization, seven-week-old male received 0.9% saline as a control, 0.02 mg/kg DON T1, 0.2 T2 via oral gavage for 4 weeks. The final body weight group was significantly...
Hanwoo and Jeju Black cattle (Jeju Black) are native breeds of Korean cattle. recognized as natural monuments known to exhibit slower growth rates compared Hanwoo. While several studies have analyzed the genetic characteristics these cattle, there has been limited research on differences in their microbiome. In this study, rumen fluid was obtained from three steers steers, different diets (total mixed rations [TMRs] for growing, early fattening, late fattening periods) were used substrates...
Abstract The objectives of this study were to improve productivity and reduce manure odor through the addition feed additives in broiler chickens. Two hundred seventy chickens (one day old, Ross broiler) randomly assigned five treatment groups (control, 0.1AR, 0.2AR, MF, MW) with three replications (18 birds each replication). enzyme (AR, ArazymeTM 0.1, 0.2%) added was mainly protease extracted from insects. microorganisms (MF, a mixture Lactobacillus, Bacillus subtilis, photosynthetic...
