The objective of this experiment was to evaluate the effect of bull exposure on ovarian cyclicity in postpartum Murrah buffaloes. Twentyone buffaloes between the fi rst to fi fth lactation, which had calved during September and early February, were assigned at random to receive one of the following two treatments: (1) exposure to a vasectomized bull (bull exposed, BE) and (2) isolated from bull...

oxidative stress has been identified as a crucial factor leading to male infertility largely due to peroxidativedamage to the sperm cell membrane. cadmium (cd) is a widespread environmental pollutant and oneof the well-known reproductive toxicants. because of its long biological half-life (10–30 years), cdaccumulates in the biological systems. the present study was designed to assess the concen...

in the present study, the fertilizing potential of semen recovered from slaughtered bulls epididymis was evaluated after cryopreservation, by conventional techniques and flow cytometry methods. the cauda epididymal was dissected and sperm were recovered and evaluated for volume, sperm concentration, and membrane and acrosome integrity using a flow cytometer. sperm fertility potential was tested...

The study aimed to determine the physical and physiological response of Madura bull as a breeding source. This used 30 bulls aged >12-24 months at Waru Sub District, Pamekasan District. evaluation was performed including qualitative quantitative characteristics. Physiological evaluated based on rectal temperature, respiration rate, pulse rate. status measurements were carried out in morning,...

If genetic evaluations are calculated with a single-trait repeatability model, evaluation changes may be attributed in part to bulls that have daughters that deviate considerably from the typical response to aging. Differences in maturity rate of bull daughters were examined to determine whether they influence change in bull evaluations. Standardized milk records for Holsteins that first calved...

background: hormesis is defined as the bio-positive response of something which is bio-negative in high doses. in the present study, the effect of radiation hormesis was evaluated on the survival rate of immunosuppressed balb/c mice by cyclosporine a. materials and methods: we used 75 consanguine, male, balb/c mice in this experiment. the first group received technetium-99m (3700bq) and the sec...

introdouction: squamous cell carcinoma is the most common oral cancer and the prognosis because of a late diagnosis remains poor despite numerous treatments. therefore, we conducted a cross-sectional study to investigate the relationships between survival rate(sr) of oral squamous cell carcinoma (oscc) and clinical,demographic, pathological, and molecular factors in yazd city during 1998– 2008....
