Quality and Fertility of Post Thaw Sephadex Filtered Bull Semen
The present investigation was carried out to assess the effect of Sephadex (G-15) filtration on the post thaw bull semen quality and conception rate. Post thaw unfiltered (control) and Sephadex filtered semen from four healthy bulls (three cross bred and one pure bred Holstein Friesian) were subjected to microscopic examination viz. sperm concentration, individual motility, live sperm count and...
متن کاملBull Semen Evaluation Post-thaw and Relation of Semen Characteristics to Bull’s Fertility
Evaluation of the quality of cryopreserved bull spermatozoa is reviewed. The methods for the assessment of sperm quality have markedly improved over the last decades – starting with the assessment of morphological shapes and subjective motility analysis towards the more sophisticated analysis of the molecular changes in chromatin, membranes and catabolic activities of the sperm cell itself. Fun...
متن کاملRelationship between sperm ATP content and motility of carp spermatozoa.
Carp spermatozoa are immotile in seminal plasma or in saline solution of high osmolality (> 400 mosmol kg-1). These 'quiescent' spermatozoa initiate a progressive forward motility when transferred in freshwater or in saline solution with low osmolality (< 160 mosmol kg-1). In this study we investigated 'in vitro' the relationship between sperm ATP content (measured by bioluminescence) and sperm...
متن کاملPost-thaw Characteristics of Pinzgau Bull Semen following Long-term and Short-term Storage
The aim of the study was to examine sperm viability of Pinzgau bull insemination doses following longor short-term storage. Insemination doses, provided by Slovak Biological Services Inc. (Lužianky, Slovak Republic), were slow-frozen and stored in containers with liquid nitrogen for 1 18 years. The sperm samples were divided, according to the length of storage, to the short-term ( ≤ 15 years) a...
متن کاملInfluence of Bull Seminal Plasma on Post-thaw Ram Semen Parameters and Fertility
The aim of the study was to evaluate the effect of the addition of 20% bull seminal plasma to semen extenders on post-thaw sperm motility, morphology, and fertility. Two Merino rams at 3-5 years of age, 43 ewes, and one Holstein bull were used. Fourteen ejaculates were collected by the use of an artificial vagina, twice a day, at 60 min interval. Six semen ejaculates were extended with Tris-egg...
