The paper studied the ovulation rate and embryonic vitality of dam line pigs of CRP multiple cross systems.

The rule of follicle development and the ovulation of dominant follicle as well as luteinization process in estrous cycle of maiden goat of Dazu black goat (6-12 months old) were observed by using B real-time supersonic fault scanner, and the ovulation rate of the goat was counted.

To investigate the effects of active immunization with inhibin on the change of reproductive hormone contents in blood, generative organ and ovulation rate in oestrous cycle of Nyctereutcs Procyonoides were the purpose of this study.

In order to understand the molecular mechanism and the candidate genes for high fecundity in Hu sheep,sixteen adult Hu ewes,grouped into single lambling(S) and multiple lambling(M) groups,were treated for synchronized estrous and sacrificed for tissue sampling and recording ovulation number.

【Objective】 The present study was performed to investigate the relationships between the mRNA level of BMP2,BMP4,BMP6 and BMP7 gene in ovaries and the ovulation number in Hu sheep,so as to provide references for finding hyper-prolificacy candidate gene and understanding the molecular genetic mechanism of high fecundity in Hu sheep.

Superovulation Effect in Specific Pathogen-free Mice;

The Research of Methods of Superovulation and Embryo Recovery on Minipigs;

The Progress of Research on Animals Superovulation Technology;

In order to find an effective and stable method of super ovulation,81 cows were selected from 1 173 diary cattles and deals with FSH(the dosage was 400,360 and 320mg each),PG and LRH-A3 each.

ion:Make super-ovulation of Bore goat with variety ways during non-reproductive seasons.

MOET technique, namely, Super-ovulation and Embryo Transfer technique, is one new biological high-tech which has been developed till 1970s in order to improve reproductive capacity of quality female cattle.
