  • Title: [Various results of nonsurgical embryo transfer in lactating cattle under field conditions in the Netherlands].
    Author: Hoogenkamp H.
    Journal: Tijdschr Diergeneeskd; 1984 Mar 15; 109(6):245-9. PubMed ID: 6710467.
    Abstract:
    Superovulation was induced in 129 lactating donor cows for embryo transfer under field conditions. Twenty-nine animals (22.5 per cent) responded with fewer than three corpora lutea. The number of animals flushed was ninety-nine, averaging 8.2 corpora lutea per donor cow. The average proportion of recoveries was 56.4 per cent. The quality of the embryos was satisfactory in 64 per cent of the cases. The average number of embryos and egg cells per donor was 4.6, which resulted in 2.9 good quality embryos per donor. The percentage of pregnant recipients was 56 in good quality embryos and 9 for fair quality embryos.
