Stud bull plays an important role in the development of animal husbandry. Detailed knowledge about maintenance behavior of stud bulls is essential for practicing better management conditions in the farm to support the artificial insemination (AI) industry demand. Therefore, a comparative study was conducted on stud bulls to evaluate the effect of genetic group, season, genetic group × season in...

Sixteen (mean age = 1.1 +/- 0.1 yr; mean BW = 478 +/- 34 kg) Brahman-influenced bulls were used to determine the influence of fescue type on sperm characteristics and serum concentrations of prolactin, cortisol, and testosterone. Bulls were blocked by BW, scrotal circumference (SC), and pregrazing sperm characteristics and randomly assigned to graze toxic endophyte-infected (EI; 4 bulls/pasture...

Two experiments were conducted to characterize changes in serum hormones prior to and during puberty in bulls and to study effects of castration or shortening the scrotum on these hormonal changes. In the first experiment, four of eight prepubertal bulls (135 days old) and four of eight pubertal bulls (278 days old) were left intact and four of each group were castrated. Two weeks later, serum ...

The breeding soundness evaluation (BSE) was used to evaluate Senepol (Bos taurus) bulls (n = 495) on St. Croix over a 7-year period. Young, unproven bulls (10-26 months of age) and breeding bulls (16 months to 8.5 years) were tested prior to sale or use in breeding. Inbreeding coefficients were determined for a subset of bulls (n = 290). The percentage of bulls passing the BSE increased (P < 0....

The term „Electronic Service Market“ (ESM) can be decomposed into the parts „market“, „service“ and „electronic“, i.e., the allocation mechanism of the market is used to co-ordinate service utilisation in a computer-supported way. This definition restricts that for electronic markets from [Schm93] to the provision and consumption of on-line available services. In an ESM, all transaction phases ...

the objective of this work was to determine the effect of sex, breed and birth season of calves on intensity of mllt (musculus longissimus lumborum et thoracis) area changes and development of the selected body parts in bulls and heifers of blonde d´aquitaine (ba) cattle during rearing period. two generations of bulls (n=63) and heifers (n=68) of blonde d´aquitaine (n=61) and crossbreds c×ba (c...
