The objectives of the present study were to determine the effects of six different antibiotics in controlling the growth of semen contaminating bacteria and if these antibiotics have any adverse effect on Awassi ram spermatozoa. Semen samples from six mature Awassi rams were used in this study. A total number of 120 ejaculates were collected from the rams using an artificial vagina once a week....

The aim of the present study was to investigate the effect of in vitro supplementation of selenium on fresh and frozen spermatozoa quality of buffalo (Bubalus bubalis) bulls. Five healthy buffalo bulls (5 ejaculates from each bull) were used. Each ejaculate was diluted at 37 ˚C with tris-based extender containing 0 (control), 0.5, 1, 2, 4 and 8 µg mL(-1) sodium selenite and the sperm motility a...

The objective of this study was to compare the number of recovered spermatozoa, in different parts of the uterine horn and oviduct in gilts, after insemination with fractionated (experiment) and non-fractionated (control) liquid stored semen. The number of spermatozoa and volume of backflow was also investigated. Twenty three cross-bred gilts were used in the study. They were divided into 2 gro...

this study was carried out to investigate effects of copper sulphate (cuso4) additive to semen extenders on sperm parameters: progressive motility, viability, membrane integrity and dna damage, after semen dilution and cryopreservation. semen samples of 5 buffalo bulls of 3-5 years old were collected at 5 different occasions during the autumn 2011. a total number of 25 samples were used in each...

An improved moveable in vacuo XUV fluorescence detection system was employed for the laser cooling of bunched relativistic (β = 0.47) carbon ions at Experimental Storage Ring (ESR) GSI Helmholtzzentrum Darmstadt, Germany. Strongly Doppler boosted (∼90 nm) emitted from a forward light cone after excitation 2s–2p transition (∼155 by new tunable pulsed UV (257 nm). It shown that detected strongly ...
