Norgestomet and gonadotropin-releasing hormone enhance corpus luteum function and fertility of postpartum suckled beef cows.
In Exp. 1,101 suckled beef cows were administered two injections of prostaglandin F2 alpha (PGF2 alpha) 11 d apart. Cows in Group 1 received no additional treatment. Cows in Groups 2 and 3 received 250 micrograms of GnRH plus 47-h calf removal. Cows in Group 3 also received a norgestomet ear implant that was inserted 4 d after the first PGF2 alpha injection and left in situ for 8 d. The second ...
متن کاملDual effects of nitric oxide in functional and regressing rat corpus luteum.
The present study investigated the effect of nitric oxide (NO) on the lifespan of the corpus luteum (CL). Using a competitive nitric oxide synthase (NOS) inhibitor, L-nitro arginine methyl ester (L-NAME, 600 micromol/l), and a long-life NO donor, diethyl-aminetriamine (DETA-NONOate, 10(-8), 10(-6) or 10(-4) mol/l), we found that in ovaries from rats at the mid stage of CL development, endogenou...
متن کاملRelationships between follicle and corpus luteum diameter, blood flow, and progesterone production in beef cows and heifers: preliminary results
The aim of the present study in beef cattle was to investigate potential differences in follicle size and follicle wall-blood flow between cows and heifers and to compare follicle wall-blood flow between smaller and larger follicles. Cows and heifers were treated with a synchronization protocol and follicles and CLs were measured and evaluated for blood flow. Pregnancy diagnosis was performed o...

15 صفحه اولIdentification of microRNAs in corpus luteum of pregnancy in buffalo (Bubalus bubalis) by deep sequencing
This study was aimed to identify miRNAs of corpus luteum (CL) in buffaloes during pregnancy. For this study, CL (n=2) were collected from gravid uteri of buffalo and RNA was isolated. Following this, the purity and integrity of RNA was checked and used for deep sequencing using Illumina Hiseq 2500 platform. The reads’ quality was checked prior to in silico analyses viz. identification of conser...
