Abstract

The objective of the work was to study the cleavage rate of in-vitro fertilized embryos of caprine oocytes. A total of 3490 oocytes were retrieved from 812 caprine ovaries of abattoir origin. Recovery rate of oocytes per ovary was recorded 4.3. Oocytes were matured in-vitro in TCM-199 containing supplements for 27 hr in humidifier atmosphere of 5% CO2 at 38.5 ºC in CO2 incubator.  Maturation rate was 89.025 per cent. The results of the present study revealed that the overall cleavage rate through in-vitro fertilization was 14.8%. Out of total cleaved embryos, 134 two cell stage embryos were used for tetraploid embryo production. Developmental stages of remaining cleaved embryos were recorded (2 cell; 18.40%, 4 cell; 9.81%, 8-16 cell; 4.29%, morula; 0.92%, blastocysts).
