In Mexico, there is a wide variety of breeds of bovines, goats, sheep<br />

<strong>and</strong> wild deer, that are either indigenous to the area or imported from<br />

other countries. They are used for the production of meat, milk, for<br />

hunting ranches , in zoos <strong>and</strong> circuses. Due to injuries <strong>and</strong> trauma in<br />

the fields, during transportation, fighting <strong>and</strong> other causes, these<br />

animals suffer various types of fractures of long bones such as<br />

femur, fibula, radius, <strong>and</strong> also of the metatarsi <strong>and</strong> metacarpi .The<br />

Faculty of Veterinary Medicine of the National University of<br />

Mexico recieves cases from submitted by veterinary practitioners<br />

from all over the country <strong>and</strong> also directly from zoos or from animal<br />

owners everywhere in the country. In the last few years we have<br />

been asked to reduce fractures using implants such as plates, screws,<br />

circlage, intramedular pins. In this poster, we present 12 cases<br />

of traumatized animals, 11 of which were treated with implants <strong>and</strong><br />

one had to be amputated due to the severity of the injury. The group<br />

included five deer, a wild goat, two bovines (bos taurus) <strong>and</strong> one bos<br />

indicus,<strong>and</strong> three hampshire sheep. The procedures were successful<br />

in all the deer <strong>and</strong> sheep <strong>and</strong> also in one bos taurus, while in the bos<br />

indicus <strong>and</strong> one bos taurus of approximately 800 kg <strong>and</strong> the wild<br />

goat, the procedure was unsuccessful. The male bulls twisted the<br />

plates as soon as they stood on their legs <strong>and</strong> the wild goat died of<br />

causes unrelated to the surgery. Two of the sheep <strong>and</strong> the female bos<br />

taurus were implanted with plates <strong>and</strong> screws <strong>and</strong> had a good<br />

evolution. In the same way, the deer whose fractures were treated<br />

with Steinman pins had a good recovery. The failures in the bulls<br />

were due to the excess weight. The Steinman pin worked well in<br />

animals whose weight ranged between 35 <strong>and</strong> 40 kg <strong>and</strong> the plates<br />

were satisfactory in two sheep that weighed 35 kg <strong>and</strong> a female bos<br />

taurus that weighed 225 kg. The experience obtained with these<br />

cases makes us conclude that plates should not be used in animals<br />

weighing over 250 kg <strong>and</strong> that the Steinman pins are very<br />

satisfactory for use in small domestic or wild ruminants f. e. the<br />

white tailed deer, goats, sheep <strong>and</strong> dama fallow deer.<br />

The efficacy of Finadyne ® injectable was evaluated for treatment of<br />

induced inflammation of the subcutis in cattle. It was assessed by<br />

comparing in a cross-over designed trial the effect of Finadyne ® on<br />

exudate PGE 2 concentration to that of Metacam ® <strong>and</strong> 0.9% NaCl<br />

solution. Twelve healthy calves (183.3 ± 39.1 kg) were included in<br />

the study <strong>and</strong> r<strong>and</strong>omly assigned to three treatment sequences.<br />

Sterile hollow perforated polyethylene balls were surgically<br />

embedded in the subcutis at four distinct sites per animal two weeks<br />

prior to D0. On D0, D21, <strong>and</strong> D42, an aseptic inflammation of the<br />

subcutis was induced by injecting in three balls per animal 0.5 ml of<br />

a 2% carrageenan solution. Treatment immediately followed. 0.5 ml<br />

of exudate was collected prior to challenge, <strong>and</strong> 2, 4, 8, 12, 24, 36,<br />

<strong>and</strong> 48 hours after. Cages were emptied after each collection.<br />

Exudate PGE 2 concentrations were measured using a validated<br />

ELISA kit. Each animal received all three items as treatment<br />

sequentially on D0, D21, <strong>and</strong> D42. PGE 2 pre-challenge<br />

concentrations were near 0. PGE 2 concentration levels over time<br />

displayed a post-challenge sharp increase, peaked 2 hours after<br />

treatment <strong>and</strong> gradually decrease, returning to baseline values within<br />

48 hours. Curves were similar over all three periods.PGE 2<br />

concentrations when treated with Finadyne ® or Metacam ® were<br />

consistently lower than those measured when treated with NaCl.<br />

Percent of inhibition was highest at +4 hours after treatment.<br />

Differences (absolute values) with the placebo were significant<br />

throughout the post-treatment period (up to 48 hours) for Finadyne ®<br />

<strong>and</strong> at +2, 4, 8, <strong>and</strong> 12 hours after treatment with Metacam ® .<br />

Differences in pre-dose concentrations among calves were<br />

accounted for by dividing post-dose PGE 2 concentrations by predose<br />

PGE 2 concentrations for each calf. Mean PGE 2 concentrations<br />

in the NaCl group were significantly higher compared to those in the<br />

Metacam ® group at 2 <strong>and</strong> 4 hour, <strong>and</strong> close to significance at 8, 12,<br />

24 <strong>and</strong> 36 hours. They were significantly higher than those in the<br />

Finadyne ® group throughout the study. At 36 <strong>and</strong> 48 hours after<br />

dosing, the mean PGE 2 concentration in the Metacam ® group was<br />

significantly higher than in the Finadyne ® group. This study shows<br />

that both items inhibit cyclo-oxygenase with a more potent <strong>and</strong><br />

residual inhibitory activity of Finadyne ® compared to Metacam ® .<br />

Displacement of the abomasum is probably the most common<br />

surgical condition of bovine patient. Left displacement of abomasum<br />

is a multi factorial syndrome by many caves. the results <strong>and</strong> finding<br />

of studies (cause, number of parturition) may be different in different<br />

geographic location.The study were done on 157Dairy cattle with<br />

LDA in some dairy farms in Tehran .The goal of this study is to find<br />

the answer for some questions (age, sex, number of parturition ) .The<br />

results showed that 96.5% of cases were in female <strong>and</strong> 3.2% in male<br />

sex. The other results were as follows: 2.6% of cases were heifers<br />

25% in first parturition, 7.2% in 2th parturition 35.5% in 3th<br />

parturition, 25% in 4 th parturition 4.6% in 5 th parturition 1.3% of<br />

cases were in before parturition 0.7% in first week after parturition<br />

2.07% in 2 weeks after parturition 50% in 3 weeks after parturition<br />

10.5% in 4 th weeks after parturition 15.8% in 5 th weeks after<br />

parturition 8.06% of cases recovered after surgery completely 5.3%<br />

were culled for some complications 13.7% of cases were culled for<br />

accompany diseases .<br />

Objectives: Research was done on the efficacy <strong>and</strong> safety of lidocaine<br />

during endoscopic procedures of the upper respiratory tract in cattle.<br />

Patients <strong>and</strong> Method: Experiments were performed in healthy non<br />

lactating cows. Eight minutes after intranasal (IN) or intravenous (IV)<br />

application of lidocaine (1.5 mg/kg), both given over a period of 5 min,<br />

rhinotracheobronchoscopy was performed. Experiments were<br />

videotaped for subsequent analysis of behavioural changes. Mean<br />

invasive arterial blood pressure (MABP) <strong>and</strong> heart rate (HR) were<br />

analysed at specified time points. Blood samples were taken up to 60<br />

min in order to measure serum lidocaine concentrations.<br />

Results: Preliminary data show that lidocaine did not lead to<br />

significant cardiovascular reactions in cattle, neither after IN nor<br />

after IV administration. In the present study absorption of lidocaine<br />

was generally rapid after IN application. During the procedure of<br />

rhinotracheobronchoscopy, HR <strong>and</strong> MABP increased slightly in all<br />

groups (lidocaine IN, IV <strong>and</strong> the control groups). Lidocaine<br />

significantly improved the animals’ tolerance during rhinoscopy,<br />

especially when given IN. Insertion of the endoscope into the trachea<br />

was eased in both, the lidocaine IN <strong>and</strong> the lidocaine IV group.<br />

Discussion <strong>and</strong> Conclusion: We conclude from our results that<br />

lidocaine is a safe <strong>and</strong> effective analgesic option for endoscopic<br />

procedures of the upper respiratory tract when given at a dosage of<br />

1.5 mg/kg. On the basis of our results we favour intranasal over<br />

intravenous application of lidocaine for rhinotracheobronchoscopy<br />

in cattle.<br />
