In vitro evaluation of in vivo fertilizing ability of frozen rabbit semen.
The present work studied different spermatozoa parameters and the ability of frozen rabbit spermatozoa to fertilize, in vitro, in vivo-matured oocytes, as a test to predict their in vivo fertility and prolificacy. Semen from rabbit bucks was frozen using two freezing protocols [in a freezer at -30 degrees C or in liquid nitrogen vapour (LNV)]. For the in vivo trial, females were inseminated wit...
متن کاملFertilizing ability of turkey semen diluted with simple sugar-based extenders after cooled storage
It is now possible to store turkey semen for 4 to 24 h without appreciable loss in fertility and hatchability. Optimum conditions for 24 or 48 h storage have not been fully determined. Development of new storage media, allowing the insemination of very low numbers of spermatozoa, may provide interesting possibilities regarding the use of superior sires. This study was conducted to evaluate effe...
متن کاملSLOPE PROFILE MORPHOMETRY AS AN INDICATOR FOR SLOPE MOVEMENT
Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...
