چکیده

experiment was conducted to study the effect of different antibiotics on sperm quality of ram by a completely randomized block design using 23 factorial arrangement with 2 block and 4 observations in each experimental units. factors include three antibiotics named gentamycin (g), lincomycin (l) and ampicillin (a) that were used at two different levels including zero and, respectively 5, 10 and 2.5 μg / ml of diluents. tris-based and skimmed milk-based diluents were considered as block1 and block2 respectively. semen was collected from four rams in 8 times. samples were aggregated and divided into eight equal parts. the different levels of antibiotics were added to each part. samples temperature was reduced at a rate of 0.25° c/min to5° c and was stored at this temperature for 72 hours. sperms evaluations were performed at 0, 24, 48 and 72 h after storage. the interactions between antibiotics on the progressive mobility, plasma membrane integrity and viability of sperm were significant (p

Effect of Different Levels of Vitamin C and Zinc on Sperm Quality Characteristics of Arabi Ram

During the semen storage, oxidative damage is one of the major causes of reduced motility and fertility of spermatozoa. Therefore, antioxidants such as zinc and vitamin C in seminal plasma may be have the important effects on reduce the lipid peroxidation of spermatozoa by prevent the destroy effect of ROS. The aim of this study was to evaluate the effect of different levels of vitamin C and zi...

Effect of different levels of egg yolk on ram sperm coating and preserving at 5°C

Experiment was conducted to evaluate the effect of different levels of egg yolk for coating and storing spermatozoa. Ejaculates were collected from four rams. In each session, second ejaculates (n=4) were collected in a tube containing 1 mL coating buffers which were prepared by 10, 15 or 20% egg yolk plus Tris-fructose. Samples were pooled, centrifuged and the supernatant removed in the labora...
