Turkish Journal of Veterinary & Animal Sciences

The liver damage and obstructions of the biliary tract were evaluated ultrasonographically in experimentally bile duct ligated dogs. Seven healthy dogs of different breeds were used. The common bile duct was double ligated at the duodenal region after clinical and ultrasonographic examinations. After that, clinical examinations, biochemical analyses and examinations of the liver, gallbladder and biliary tract were done ultrasonographically over 6 weeks. All dogs were necropsied and macroscopic and histologic alterations were determined at the end of the study. It was determined that the levels of serum ALT, ALP, GGT and T. Bilirubin were (p < 0.001-0.05) statistically significantly increased after the operation in all dogs. As a result of ultrasonographic examinations, it was determined that the bile ducts and gallbladder were distended, the neck of the gallbladder was larger and more tortuous than normal, hypoechoic sludge was prominent in the gallbladder, and perivascular, multifocal hyperechoic areas appeared in the liver parenchyma toward the end of the study. These alterations were confirmed macroscopically and microscopically at the end of the autopsy in all dogs. We consider that as well as blood serum parameters, ultrasonographic examinations are useful in the early diagnosis of biliary diseases and in differentiating them from hepatic diseases.

This research was carried out to determine the effect of various milk sampling intervals and different methods on the accuracy of estimation of lactation milk yield in dairy cattle. Individual daily milk weights of 599 Holstein, Simmental and Brown Swiss lactations from the Aegean Agricultural Research Institute were used. It was assumed that test-day milk yields were obtained by regular and irregular intervals of 28 d and 56 d, with the irregular intervals having a standard deviation of 5 d. From test-day milk yields, 305 d milk yields were estimated by the Holland (Lactation yield = mean of test day …

Two methods to measure target strength (TS) are introduced and compared with each other. One is the suspension method, and the other is the split-beam method. Each of them is representative of control and in situ methods, respectively. In addition, a morphological investigation of a swimbladder in a pressure tank, and the development of an instrumented package of acoustic and optical systems, are also introduced. The former is to reveal the degree of TS variation by the vertical movement of fish, and the latter is to obtain precise TS and fish behavior by the echo trace analysis method.
