Abstract
This study was conducted to explore the possibility of making use of ova collected from slaughtered cows from local abattoirs. The recovered ova was cultured in vitro in artificial media for in vitro maturation (IVM) and invitro fertilization (IVF).
The ova collected was 115 from 31 ovaries, over a period of about 3 months. After maturation (IVM), 20 ova were fertilized. Of these, 45% reached the two cell stage, 20% reached the four cell stage, 15% reached the 8 cell stage and 20% reached the morula stage. These low rates of the developed embryos are comparable to many studies conducted elsewhere (30%).
The study indicated that such methods could be advantageous in getting hold of cows embryos with very little cost especially for the studies that do not require a large number of embryos.
