Abstract

Background: Conception is a fundamental trait for successful cattle reproduction. However, conception rates in Japanese Black cattle have been gradually declining over the last two decades. Although conception failures are mainly caused by embryonic mortality, the role of maternal genetic factors...

Abstract

Brahman-cross calves exhibit unusual inheritance of birth weight: Brahman-sired crossbreds out of Bos taurus females are heavier with greater difference between sexes than calves of the reciprocal cross. The objectives of this work were to confirm that unusual inheritance and to investigate...

Abstract

90 KE strain ♀ mice aged 9-12 wks. were artificially inseminated about 18 hrs. after the injection of HCG to induce ovulation. The ♂♂ that provided the spermatozoa were of 2 genotypes: inbred KE and crossbred F1 (KP ♂ x KE ♀). The spermatozoa were either epididymal or collected from the uteri of...

Abstract

The DNA content of morphologically normal spermatozoa was determined in 300 cells each in Mus musculus, Mus poschiavinus and their F1 hybrids. In contrast to the parents, the F1 hybrids showed a high degree of spermatocyte aneuploidy. The variation of DNA content in spermatozoa of F1 hybrids was...

Abstract

Body weight at birth and 5 wk of age was studied in mice of the C57 and KE strains and in 3 sublines of the CBA strain. No difference in body weight was found between the CBA sublines, and no heterosis was observed in their F1 hybrids. At birth, mice from inter-strain crosses were heavier than at...

Abstract

Animal Breeding. Progress is reported on 16 projects. Results were obtained for crossbred lamb performance of 4 breeds of ewes; Galway, Wicklow Cheviot, Greyface (Border Leicester x Scottish Blackface) and Halfbred (Border Leicester x Wicklow Cheviot). Data on Galway fleeces showed considerable...

Abstract

Heterospermic litters were obtained from virgin ♀ mice of the KE and KP strains artificially inseminated with mixed KE + KP sperm. Females that had some embryos sired by each ♂ were examined from the 13th (KE ♀♀) or 14th (KP ♀♀) day of gestation until parturition. F1 hybrid embryos in heterospermic ...
