The present study was conducted to determine the correlation of hypo-osmotic swelling test with conventional semen evaluation parameters of fresh semen collected from two Nili-Ravi buffalo and two Sahiwal cow bulls. A total of 10 pooled samples (each comprising two consecutive ejaculates) from each bull were collected. Each semen sample was divided into two parts. One part was used for the eval...

A comparative study of the sialic acid content of semen, serum and spermatozoa from several mammalian species was made. The sialic acid content of semen showed a very wide range of concentration in the four species examined, while the sialic acid concentrations in serum were much more uniform. The semen from man and bull contained higher concentrations of sialic acid than the serum of these res...

Studies showed that assisted reproductive technology changed the sex ratio at birth, but the effect of semen processing (swim-up technique and density-gradient separation) on enriching either Xor Y-bearing sperm is always controversial. We recruited 30 healthy males and their semen samples were obtained by masturbation after sexual abstinence for 2-7 days. Each sample was divided into 3 aliquot...

The study had two objectives, namely, to estimate the andrological disorders leading to disposal of Karan Fries (KF), Sahiwal cattle and Murrah buffalo bulls and to study the effect of various factors (species/breeds, season of birth and period of birth) on male reproductive parameters. Records on occurrence of subfertility problems and disposal pattern of bulls maintained at the National Dairy...

It is generally thought that a single ejaculate is a bad predictor of semen quality of a subject, because of significant intra-individual variation. Therefore, we investigated the degree to which the results of a first semen analysis differ from that of a second analysis among men from a general population in Norway. In addition, we analysed how the two different semen results mirrored the over...

Maintaining a successful pig artificial insemination programme depends on a number of factors, including evaluation of semen characteristics. This study compared the efficacy of different extenders on the sperm motility of Kolbroek semen during short term storage at 4 °C and 25 °C. Semen was collected from Kolbroek boars using the gloved hand technique and transported to the laboratory for eval...

AIM The present study was conducted to investigate the effect of species, breed and age on bacterial load in fresh and frozen semen of Cattle and Buffalo bull. MATERIALS AND METHODS Present study covered 56 cow and 10 buffalo bulls stationed at Central Semen Station Anjora, Durg (Chhattisgarh). Impact of breeds on bacterial load in semen was assessed using six breeds of cattle viz. Sahiwal, G...

A suitable method for the cryopreservation of donkey semen would be very valuable for the ex situ management of genetic diversity in this species. This report uses a variety of observation and trials to evaluate the effect of cryoprotectants in per-cycle pregnancy rates (PC) in equids females (jennies (donkey) and mares (horse)). This was explored by (1) comparing the results of insemination of...

Frozen semen is produced through several stages, which deteriorate spermatozoa. This research aimed to evaluate the deterioration degree of frozen after 5 °C cooling and freezing Bali cattle. The samples included 10 male cattle with a body weight 542-668 kg, from was collected once week for five weeks. each individual’s sperm determined by observing two distinct straws. parameters observed viab...

BACKGROUND The aim of the study was to evaluate the quality of fresh raccoon dog semen and raccoon dog semen stored at 4 °C. The qualitative evaluation was based on apoptosis in the sperm cells, which was tested by the Annexin V/Pi assay, the TUNEL method and JC-1. In addition, the suitability of the semen for insemination and its effect on reproduction in females were determined in relation to...
