INFERTILITY IN INBRED EWES

Genome-Wide Association Mapping for Female Infertility in Inbred Mice

The genetic factors underlying female infertility in humans are only partially understood. Here, we performed a genome-wide association study of female infertility in 25 inbred mouse strains by using publicly available SNP data. As a result, a total of four SNPs were identified after chromosome-wise multiple test correction. The first SNP rs29972765 is located in a gene desert on chromosome 18,...

The Mechanism of Temporary Infertility in Ewes Grazing Oestrogenic Subterranean Clover Prior to and during Joining

Ewes in which oestrus had been synchronised were artificially inseminated (at the second synchronised oestrus) 17 to 21 days after placement on plots containing either oestrogenic (Trifolium subterraneum L. c% Dinninup) or non oestrogenic pasture. A comparison of the reproductive performance indicated that grazing oestrogenic pasture prior to and during joining reduced the proportion of ewes in...

Calcium metabolism in pregnant ewes.

I . A combination of balance and isotope techniques has been used to study calcium metabolism in ten sheep at different stages of pregnancy, and the results have been combined with earlier results obtained during lactation to show the variations in Ca metabolism which occur during the whole reproductive cycle. 2. Transfer of Ca to the foetuses during pregnancy and to the milk after parturition ...
