Mitigation of Natural Hazards and Disastersn rates and early embryonic mortality. Animals were immunized such that the interval from booster injection to mating was controlled to give either high or low antibody titre levels. Immunization significantly increased ovulation rates, being 1.49, 2.23 and 1.88 for control, high and low groups resporiginality 发表于 2025-3-25 15:44:52

It is believed that interfarm variation and recipient quality contribute to the variation. The percentage of recipALERT 发表于 2025-3-25 17:24:13

In this short review, this is shown in experiments using epididymal spermatozoa and also inferred from data from field results in cattle and sheep breeding. Factors involved in these processes are the genetic make up (breeds, strains, chromosomal abnormalities), environment (pAmbulatory 发表于 2025-3-25 21:31:39

It can be concluded that of the categories of chromosome mutants that are mostly of concern for embryonic death, aneuploidy and polyploidy, man has the highest incidence of both.
