Condensed tannins (CTs) account for up to 20% of the dry matter in forage legumes used as ruminant feeds. Beneficial animal responses CTs have included improved growth, milk and wool production, fertility, reduced methane emissions ammonia volatilization from dung or urine. Most important is ability such forages combat effects gastrointestinal parasitic nematodes. Inconsistent were initially attributed concentration diet, but recent research has highlighted importance their molecular...
This study investigated the separate and combined anthelmintic (AH) effects of different phenolic compounds, including condensed tannins flavonoids, all which are known to occur in willow leaves, a potentially valuable dry season feed. A range contrasting model tannins, span whole were isolated from tilia flowers, goat black currant leaves red leaves. All together, tested compounds represented major tannin types (procyanidins prodelphinidins) flavonoid (flavonols, flavones flavanones). The...
Plants containing condensed tannins (CTs) may hold promise as alternatives to synthetic anthelmintic (AH) drugs for controlling gastrointestinal nematodes (GINs). However, the structural features that contribute AH activities of CTs remain elusive. This study probed relationships between CT structures and their activities. Eighteen plant resources were selected on basis diverse structures. From each resource, two fractions isolated in vitro measured with larval exsheathment inhibition assay,...
The variable anthelmintic efficacy of condensed tannins (CT) against gastrointestinal nematodes may depend on CT concentration, composition, or fate along the digestive tract. We analyzed concentration and composition by acetone–HCl–butanol thiolysis coupled to HPLC-MS in digesta feces lambs. Lambs had been infected with Haemonchus contortus Trichostrongylus colubriformis received sainfoin pellets hazelnut skins contrasting prodelphinidin/procyanidin ratios. lower concentrations than...
Abstract The Alpine goat ( Capra aegagrus hircus ) is parasitized by the barber pole worm Haemonchus contortus ). Hematological parameters from transcript and metagenome analysis in host are reflective of infestation. We explored comparisons between blood samples control, infected, infected zoledronic acid-treated, antibody (anti-γδ T cells) treated wethers under controlled conditions. Seven days post-inoculation (dpi), we identified 7,627 transcripts associated with different treatment...
The study aimed to assess the effects of different concentrations Ziziphus spina-Christi (ZSC) leaves on fertility buck goats. Twelve goats aged 12–15 months with an average body weight 22±2 kg were divided randomly into three dietary treatments: T1, T2, and T3, each given a basal diet daily plus feeds 20 g/kg (2%) ZSC for T1 40 (4%) T2; T3 was used as control that consumed only. experiment lasted 3 months. On days 45 90, blood samples collected plasma testosterone measurement using...
Geochelone carbonaria es una de las dos especies Tortugas terrestres que han sido descritas en Venezuela. Aquí reportamos un caso infección parasitaria severa con nemátodos estrongilidos y oxyuridos 15 tortugas la localidad Upata, Estado Bolívar, Los animales fueron capturados sabana por el propietario finca ganadera zona encerrados área restringida cerca. Dos meses más tarde, los se mostraron enfermos, presentando anorexia, letargia diarrea. Las heces eran fluidas, mucoides hemorrágicas....
Proanthocyanindins (PAs) from shea meal (SM), a by-product obtained after lipid extraction of the nuts, contained B-type linkages, had high ratio prodelphinidins (73%) and were galloylated (42%). The average polymer size was 8 flavan-3-ol subunits (≈2384 Daltons) epigallocatechin gallate major subunit.
The antimicrobial effects of diverse tannin-containing plants, particularly condensed tannins (CTs) produced from various are the subject this study. CT components can be determined using CT-specific procedures such HCl-Butanol Acetone assay, Thiolysis reaction, and HPLC/MS analysis. These methods indicate contents, including mean degree polymerization, procyanidins prodelphinidins ratio (PC/PD%), isomers trans- cis-, concentration. Tannin-containing plants possess antibacterial action,...
Abstract The focus of this research was to investigate how tannin extract from black tea influenced the hematological and histopathological evaluations male rabbits fed a mycotoxin-contaminated feed, including 17 ppb aflatoxin, 5 ochratoxin 2 fumonisin. A total 28 local were allocated into four groups, first which control group. second Mycotoxin-contaminated meal. third given Mycotoxin feeding with extracts (125mg/mL per head) administered orally, while fourth contaminated diet (250 mg/mL...
Abstract Resistance to internal parasites (IP) is important in the sustainability of a meat goat enterprise. Langston University (LU) and American Kiko Goat Association conducted SecondGeneration Buck Performance Test 2019. The performance test measured fecal egg count (FEC) packed-cell volume (PCV) natural challenge 6 wk on pasture (PAS) an artificial dry-lot confinement (CON). Seventy-seven bucks less than 1 yr age completed both PAS CON. was 23-ha with native grasses forbs. Bucks were...
Abstract The interaction between inclement weather and disease acquisition is a long-recognized relationship. In the case of coccidiosis, parasitic infestation intestines, wet known to promote incidences in livestock. Our opportunistic investigation tracks blood chemistries goats that were exposed coccidian 100 year rain event Oklahoma. results suggest potentially patterned response may be developed into clinical tool future provide warnings for producers risks associated with growing...
