Research plan: 

Research plan 3 Oocyte collection IVM Oocyte fixation and staining IVF IVC Vitrification Vitrification

Oocyte collection: 

Oocyte collection 4 Slaughter house 35 o C, 0.9% NaCl solution Aspirated follicle from bovine ovary with 18 –gauge needle attached to 10 ml syringe

In vitro maturation (IVM): 

In vitro maturation (IVM) 5 Cultured in TCM 199 medium Incubate for 24 hours in 5%CO 2 in humidified air at 39 o C

In vitro fertilization (IVF): 

In vitro fertilization (IVF) 6 Sperm preparation two straw thawed at 37 o C for 30 seconds. the thawed semen will be layered on Percoll medium centrifuged at 900 rpm for 15 minutes In vitro insemination 44 u l drop of IVF-TL incubate for 2 hours. 10 COCs will be transfer to IVF-TL and co-incubated for 24 hours in 5%CO 2 in humidified air at 39 o C.

In vitro culture (IVC) : 

In vitro culture (IVC) 7 After co-incubation, vortexed for 1-2 minute and culture in IVC medium for next 135 hours 5%CO 2 in humidified air at 39 o C for blastocyst.

Vitrification: 

Vitrification 8 Vitrification means cooling without formation of ice. It is the process to preserve the oocyte or embryo by liquid nitrogen for long time. Storage in LN 2

Objectives of this plan: 

Objectives of this plan To investigate the In vitro production of embryo in cattle To develop the high productive cattle breed To bypass the dependency of whole follicular development in cattle To increase the livestock population
