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 />
