BACKGROUND European bison is the largest mammal in Europe with the population of approximately 4000 individuals. However, there is no report of post-mortem spermatozoa collection and cryopreservation from this species and the aim of this study was to test if the epididymal spermatozoa collected post-mortem from European bison are suitable for cryopreservation and artificial insemination (AI). ...

Animal related injuries are frequently reported in countries where the bulls are used for traditional show events like bullfighting and bull-running as well as in countries where the farming and livestock rearing is predominantly practiced. Although, they are rare among other penetrating traumas, they often tend to be mortal. They have a unique pattern of injury mechanism. Bull gore injuries fr...

—The bull trout Salvelinus confluentus is believed to be among the most thermally sensitive species in coldwater habitats in western North America. We conducted a comprehensive field assessment of thermal habitat associations throughout the southern margin of the species’ range. We developed models of thermal habitat associations using two data sets representing a geographically diverse range o...

Twoand 3-year-old beef bulls were exposed to 25 or 40 beef cows on pasture during a 90-day breeding period. Reproductive performance of bulls by age of bull and size of cow group was evaluated in terms of percentage calf crop. Results indicated that reproductive performance of 2-year-old bulls was higher, but not significantly different (P>.05), than that of 3-year-old bulls. The percentage cal...

This paper is concerned with the optimality of a trend following trading rule. The idea is to catch a bull market at its early stage, ride the trend, and liquidate the position at the first evidence of the subsequent bear market. We characterize the bull and bear phases of the markets mathematically using the conditional probabilities of the bull market given the up to date stock prices. The op...

the aim followed in this study was to make a comparison of the composition of fatty acids available in the sperm lipids of cattle, sheep and goat. semen samples were collected from 28 holestein cows, 12 chal rams and 7 mahabadi goats. after washing out and removal of the seminal plasma, total lipids of the sperm were extracted and fatty acids trans-methylated. the fatty acid methyl esters were ...

to determine the role of ddx3y gene in spermatogenesis and infertility in bulls, blood samples were collected from five infertile bulls (azoospermic; no sperm in the semen) at the animal breeding center in karaj, iran. the recommended human primers by eaa/eqmn were investigated using the blastn database for sts marker detection. alignment of sts marker genes with bovine genome was performed. pr...
