objective: the effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. materials and methods: in this experimental study, we randomly assigned 9 zandi rams to two groups (isoenergetic and isonitrogenous diets): control (ctr...

Insulin is present in the seminal plasma and involved sperm activities like motility capacitation. However, effects of insulin on viability cooled ram are not fully understood. Therefore, objective current study was to evaluate effect addition maintained at 5ºC. Sperm samples were collected from six healthy, mature Santa Inês rams. The ejaculates divided into two aliquots with (insulin group) o...

background: as we all know, sperm has the capacity to take up foreign dna, therefore, sperm mediated gen transfer can be an inexpensive and simple method in animal transgenesis in various species. however, there is not sufficient evidence of dna uptake by ovine spermatozoa. objectives: the purpose of the present study was to examine the uptake of human lysozyme gene contained plasmid (pegfp-ire...
