In vitro embryo production in small ruminants
This paper reviews the technical bases of in vitro embryo production in small ruminants with special attention to the results obtained by our group in Northeastern Brazil. The laparoscopic oocyte recovery in hormonally treated live animals indicates a promising future for the application of this technique to genetic improvement program. New molecular biology tools should provide information to ...
متن کاملSperm Flagellum Volume Determines Freezability in Red Deer Spermatozoa
The factors affecting the inter-individual differences in sperm freezability is a major line of research in spermatology. Poor sperm freezability is mainly characterised by a low sperm velocity, which in turn is associated with low fertility rates in most animal species. Studies concerning the implications of sperm morphometry on freezability are quite limited, and most of them are based on spe...
متن کاملDetection of Mycoplasma agalactiae in Small Ruminants of Southeast Iran
Agalactia is an infectious and contagious disease of small ruminants caused by Mycoplasma agalactiae (M. agalactiae). Although different microorganism strains contribute to this disease, M. agalactiae is known as the most prominent causative agent. Therefore, this study aimed to investigate the rate of M. agalactiae involvement in contagious agalactia in the southeast region of Iran. Sampling ...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Detrimental Effects of Non-Functional Spermatozoa on the Freezability of Functional Spermatozoa from Boar Ejaculate
In the present study, the impact of non-functional spermatozoa on the cryopreservation success of functional boar spermatozoa was evaluated. Fifteen sperm-rich ejaculate fractions collected from five fertile boars were frozen with different proportions of induced non-functional sperm (0--native semen sample-, 25, 50 and 75% non-functional spermatozoa). After thawing, the recovery of motile and ...
