Intravenous lipopolysaccharide challenge alters ruminal bacterial microbiota and disrupts ruminal metabolism in dairy cattle.
In the present study, three primiparous lactating Holstein cows (260-285 d in lactation) were used in a 3 × 3 Latin square design to assess the effects of three doses (0.0, 0.4 and 0.8 μg/kg body weight) of lipopolysaccharide (LPS, Escherichia coli 0111:B4) on changes in ruminal microbiota and ruminal fermentation. Ruminal pH was linearly decreased (P< 0.001) by LPS challenge, and the concentra...
متن کاملAcute bovine laminitis: a new induction model using alimentary oligofructose overload.
Twelve dairy heifers were used to examine the clinical response of an alimentary oligofructose overload. Six animals were divided into 3 subgroups, and each was given a bolus dose of 13, 17, or 21 g/kg of oligofructose orally. The control group (n = 6) was sham-treated with tap water. Signs of lameness, cardiovascular function, and gastrointestinal function were monitored every 6 h during devel...
متن کاملDistribution of technetium-99m PEG-liposomes during oligofructose-induced laminitis development in horses.
Liposomes are phospholipid nanoparticles used for targeted drug delivery. This study aimed to determine whether intravenous liposomes accumulate in lamellar tissue during laminitis development in horses so as to assess their potential for targeted lamellar drug delivery. Polyethylene-glycol (PEG) coated liposomes were prepared according to the film hydration method and labelled using (99m)Tc-he...
متن کاملEquine laminitis model: cryotherapy reduces the severity of lesions evaluated seven days after induction with oligofructose.
REASONS FOR PERFORMING STUDY A previous preliminary study demonstrated the potential of distal limb cryotherapy (DLC) for preventing laminitis. Clinically, DLC must be effective for periods longer than 48 h and the preventive effect must extend beyond its discontinuation. OBJECTIVES To evaluate the effect of DLC, applied during the developmental phase of induced laminitis, on the severity of ...
متن کاملSYMPOSIUM: ENVIRONMENTAL RISK FACTORS FOR LAMINITIS Environmental Influences On Claw Horn Lesions Associated With Laminitis And Sub-acute Ruminal Acidosis (SARA) In Dairy Cows
A dairy cow’s environment may influence the onset of laminitis and associated claw horn lesions by exacerbating changes in the hoof triggered by events at parturition, onset of subacute ruminal acidosis, or claw horn growth and wear and ground reaction forces on different walking surfaces. Environmental risk factors for laminitis and associated claw horn lesions include feed bunk space and desi...
