Bovine Immunodeficiency Virus (BIV) is a Lentivirus, which can cause varieties of infectious complications due to immune system dysfunctions and induce remarkable economic losses to dairy cattle industry. Considering the probability that BIV infection can be worldwide distributed and giving attention to the fact that till now not only any epidemiological survey but also any case study have not been done, therefore this is the first investigation about BIV infection in Iran. In this study 197 Holstein cattle slaughtered in Meysam abattoir in Tehran province were surveyed. The investigation began from the October 2005 and ended in March 2006. The purpose of the survey was to determine the infection rate of BIV and the effects of the infection on the clinical and pathological parameters. Nested- PCR was used in the diagnosis of the infection.The results of the study showed that total infection rate was 16.2% (32/197). The animals with four pair’s permanent teeth had the highest (26.8%) infection rate (0.01
Objective of study: Currently it is assumed, that the lung of newborn calves expands and starts gas exchange quite shortly after birth. Up to now, it was not shown at what time during the first weeks of life, different lung areas of bovine neonates show a maximum gas exchange rate. Therefore the lung development of bovine neonates within the first three weeks post natal was examined using CT. Material and methods: For the ongoing examinations of the first three weeks post natum 15 healthy Holstein Frisian calves, born without any complications, were chosen. Their vitality was checked with the APGAR-Score (>7.5) and blood-gas-analysis.The lung function was measured segmental in a spiral CT -PQ 2000- of the brand Picker International. In order to examine the thorax area, the animals were slightly sedated (Xylazinhydrochloride, Impfstoffwerke Dessau, 0.09 mg/kg body weight). The Region of interest (ROI) was chosen in a way that lung tissue without larger supply-structures (such as vessels) was measured (Roi sqnn 12): dorsal left and right quadrant, ventral left and right quadrant; from cranial to caudal direction. The CT-measuring times were: 0.5-1 h, 6 h, 12 h p. n., 1 st , 2 nd and 3 rd week p. n.The statistical analysis was made with SPSS 14.0 using variance analysis and Pearson’s correlation coefficient. Results: 1. Immediately p. n. the two dorsal lung areas are ventilated, with a delay of about 12 hours also the ventral ones (p < 0.001). 2.The expansion of the lung-alveoli increases from cranial to caudal. The time until the cranial lung areas are completely ventilated was two weeks, for the caudal areas three weeks. 3. In the cranial area, the left half of the lung is better ventilated than the right. (1 st hour p. n. until 2 nd week post natum p < 0.02 to 0.001) whereas the right caudal lung area participates more intensively after the 12 th hour post natum until the third week post natum in the increasing gas exchange than the left area (p < 0.05 to 0.001). Conclusions: A complete gas exchange activity within the bovine lung is only given with the beginning of the second week post natum. It was shown that there are significant differences in the development of the stability of lung alveoli comparing cranial and caudal lung segments as well as dorsal and ventral lung areas.

Leslie 1 1 University of Guelph, Population Medicine, Guelph, Canada 2 Iowa State University, Population Medicine, Ames, United States 3 University of Guelph, Kemptville Campus, Kemptville, Canada Infectious disease poses a major welfare challenge for neonatal dairy calves. Opportunities for supportive therapy which may alleviate animal suffering during disease states need to be identified and formally evaluated. The objective of this study was to examine whether meloxicam (Metacam ® 20 mg/mL solution for injection for cattle, pigs and horses, Boehringer Ingelheim) is an effective supportive therapy for the alleviation of sickness and pain-related behaviours in cases of neonatal calf diarrhea complex. For this double-blind controlled trial, 62 Holstein bull calves were purchased at birth and transported to a calf research facility. At the naturally occurring onset of diarrhea, the calves were enrolled in the study and randomly assigned to receive a single subcutaneous injection of meloxicam (0.5 mg/kg BW) or an equal volume of placebo solution. Starter ration and milk intakes were recorded daily for each calf until 56 days of age. Following onset of diarrhea, calf feeding behaviour, lying posture, standing posture and activity were evaluated over a five day observation period. During the study, 56 calves presented with clinical signs of diarrhea and were subsequently treated with meloxicam (n=28) or placebo (n=28). Meloxicam-treated calves began consuming starter ration significantly earlier (p1/50 (Pomona 11/24 vs. 23/23, D 54% CI 28-80%, P
