Title: The Adaptability as Recipients for ET in Cows with the Coexistences of Corpus Luteum and Follicle, and Cystic Corpus Luteum
Abstract: We discussed possibility of conception and blood progesterone concentration of recipients for embryo transfer in cows with the coexistences of corpus luteum and follicles, and cystic corpus luteum.As for blood progesterone concentration, both the coexistences of corpus luteum and follicles and cystic corpus luteum indicated the similar value as corpus luteum without follicles.Moreover, investigated changes of blood progesterone concentration from the previous day of transfer to the very day of transfer, in each case, the coexistences of corpus luteum and follicles, cystic corpus luteum and cor-pus luteum without follicles, high rise of blood progesterone concentration was recognized in pregnancy cows.The corpus luteum and follicles, if they are A rank corpus luteum, were higher conception rate whether there were follicle rupture and observation and diagnosis of external genital organs or not.By the treatment of exclusion of luminal fluid in cystic corpus luteum, the normalization of morphological investigation of corpus luteum and rise of blood progesterone concentraion were recognized. It was thought that the corpus luteum and follicles, if morphological investigation of their corpus luteum are normal, could be used as recipients.It was also thought that cystic corpus luteum could be used by removing luminal fluid.
