This study aimed to improve the quality of cryopreserved goat semen for artificial insemination by the addition of cattle seminal plasma crude protein. Semen collected from cattle and centrifuged to obtain seminal plasma. Then it was purified to obtain the crude protein. The diluent used in this study was milk-yolk. There were three groups, control group without crude protein (P0), the addition...

Milk urea nitrogen (MUN) of dairy cows was determined in relation to breed. A total of forty (40) Pabna and red Chittagong dairy cattle each of twenty (20) were selected to know the milk composition, nutritional status and milk urea nitrogen. Live weight of Pabna Cattle (187±14 kg) was higher than that of red Chittagong cattle (174±4 kg). In Pabna cattle milk yield (4.94 kg), minerals (0.15%) a...

Seminal plasma is complex fluid containing a wide variety of both organic and inorganic components, among which proteins are an important part of the high-molecular-weight substances. The protein composition of mammalian seminal plasma varies in species and has important effect on sperm functions such as sperm motility (Henricks et al., 1998), viability (Brandon et al., 1999) and freezability (...

Two experiments were designed to examine the effects of crude seminal plasma (CSP) exposure ofejaculated and epididymal spermatozoa before freezing. Experiment 1, two consecutive ejaculates werecollected (n=4) within 5 min, the second one was carried out in a tube containing Fiser extender (coatedspermatozoa); by centrifugation, seminal plasma was removed from coated ejaculates. The pellets wer...

To study the influence of season on oxidative status of buffalo semen and their association with semen characteristics and seminal plasma proteins, ejaculates were collected twice a week in winter, summer and rainy seasons from six adult Bhadawari buffalo bulls. The neat semen was analyzed for semen characteristics immediately after collection and oxidative status viz. lipid peroxidation (LPO),...

background: the human seminal fluid is a complex body fluid. it is not known how many proteins are expressed in the seminal plasma; however in analog with the blood it is possible up to 10,000 proteins are expressed in the seminal plasma. the human seminal fluid is a rich source of potential biomarkers for male infertility and reproduction disorder. methods: in this review, the ongoing list of ...

introduction: mcp (membrane cofactor protein or cd46) is a complement regulatory proteins (crps), which is present in most of body cell membranes (except erythrocytes), and also in most biologycal body fliuds. due to the important role of this protein in the complement system, specially in fertility, the aim of this study was to determine and isolate this protein in human seminal plasma. materi...

In this study, quantitive characteristics and chemical composition of in roach (Rutilus rutilus caspicus) sperm were investigated. Sperm traits included sperm movement duration, percentage of motile spermatozoa, sperm density, spermatocrit and sperm volume. Some seminal plasma characteristics (sodium, potassium, calcium, magnesium and chloride) were investigated. In addition, some metabolites o...
