Multiple superovulations in N'Dama heifers
Tropical Animal Health and Production, 1990 Five N'Dama heifers were superovulated with follicle stimulating hormone (FSH-P or Folltropin) a total of six times each. The superovulations were carried out between ongoing experimental Trypanosoma congolense infections. Twenty-four (80%) of the 30 superovulations had a good ovarian response with 21 (70%) producing an average of 2.7 +/- 0.4 (mean +/-

Development of Recombinant Follicle-Stimulating Hormone for the Superovulation of Cattle: A Review. [PDF]
Vet SciEmbryo transfer technology is extensively utilized in cattle breeding, with superovulation serving as its foundation. Superovulation currently relies on the administration of exogenous hormones to stimulate follicular development and maturation in the ...

Recent advances in the superovulation in cattle [PDF]
Reproduction Nutrition Development, 2002 The variability in the superovulatory response continues to be one of the most frustrating problems with embryo transfer in cattle. The removal of LH from pituitary extracts has tended to reduce the variability in response, and several studies involving the use of the purified porcine pituitary extract. Folltropin-V are reviewed.

Handmade Biopsy for Genotyping of In Vitro‐Produced Bovine Embryos
Anatomia, Histologia, Embryologia, Volume 55, Issue 3, May 2026.ABSTRACT Blastocyst biopsy allows genomic selection of pre‐implantation bovine embryos, reducing generation interval and enhancing the genetic gain. We aimed to evaluate the suitability of a simple biopsy procedure, performed by hands, using a splitting microblade and a stereoscope, on in vitro‐produced embryos. Crossbred Bos taurus x B.

COITAL BLOCK TO SUPEROVULATION IN THE HAMSTER [PDF]
Reproduction, 1963 Summary. Hamsters injected with 60 i.u. pregnant mares' serum (pms) on the morning of metoestrus (Day 1 of oestrous cycle) will ovulate sixty to seventy ova if they are isolated from males. However, if similarly treated females are caged with males on Day 2 or 3, coitus takes place and the inactive corpora lutea of the oestrous cycle ...
