Aim: The experiment was conducted to study the total seminal plasma protein (TSPP) and heparin-binding proteins (HBPs) in relation to initial semen quality of buffalo bull. Materials and Methods: Semen from two Murrah buffalo bulls (bull no. 605 and 790) with mass motility of ≥3+ were used for the study and categorized into three groups (Group IMass motility 3+, Group IIMass motility 4+ and Gro...

chromosomal appearance of 12 holstein bulls selected for artificial inseminations were examined bysister chromatid exchanges (sces). for differential staining of sister chromatids bromodeoxyuridine (brdu)was inoculated in lymphocyte cultures. the mean, maximum and minimum number of sce per cell weredetermined 6.8 ± 1.14, 8.3 ± 1.1 and 5.7 ± 1.5, respectively. sce frequencies of all animals were...

Selection or replacement of a herd bull is an important decision for cow-calf producers. To justify the price paid for a bull, cattlemen may utilize several criteria. They must also determine if the specific selection criteria used add or detract from the value of a particular animal. The study reported here evaluated 13 years of data presented to bull buyers at a graded bull auction in Florida...

Objectives. To assess the effect of Red Bull(©) on (1) blood glucose and catecholamine levels, (2) cardiovascular and respiratory function changes before, during, and after exercise, (3) reaction time, (4) cognitive functions, and (5) response to mental stress test and emotions in young healthy individuals (N=38).

this is a report of a penile fibrosarcoma in a two-year-old crossbred holstein bull. the ulcerated tumormass with dimensions of 7 × 9 × 6.5 cm, was enveloped the glans and body of the penis. it had a white-graycolor at cross section appearance. there was no metastatic evidence of regional lymph node enlargement.histopathologically, elongated spindle-shaped cells arranged densely in the interwov...

A bull is a graph obtained by adding a pendant vertex at two vertices of a triangle. Here we present polynomial-time combinatorial algorithms for the optimal weighted coloring and weighted clique problems in bull-free perfect graphs. The algorithms are based on a structural analysis and decomposition of bull-free perfect graphs.
