Development of estrous synchronization protocols using melengestrol acetate in Bos indicus cattle.

Five experiments were conducted on commercial farms in Brazil designed to develop the basis for an estrus synchronization protocol using melengestrol acetate (MGA) in Bos indicus cattle. These studies resulted in the development of the following protocol: 0.5 mg x d(-1) of MGA between d -14 and -1; 2.0 mg i.m. injection of estradiol cypionate on d -9; 48 h temporary weaning between d 0 and 2; a...

Delivery of cloned offspring: experience in Zebu cattle (Bos indicus).

The production of a healthy cloned calf is dependent on a multitude of successful steps, including reprogramming mediated by the oocyte, the development of a functional placenta, adequate maternal-fetal interaction, the establishment of a physiological metabolic setting and the formation of a complete set of well-differentiated cells that will eventually result in well-characterised and fully c...

Ovarian Follicular Patterns and Hormone Profile in Thai Native Cattle (Bos indicus)

The objective of this study was to characterize the patterns of ovarian follicular waves, and FSH and P4 concentration during estrous cycle in Thai native cattle (Bos indicus). Transrectal ultrasound examination of ovaries was performed daily using a 7.5 MHz transducer and blood samples were collected after the ultrasound examination during May to August, 2010. There were 1-, 2or 3-follicular w...

Characterization of yolk sac proteins of Bos indicus cattle embryos.

The yolk sac is an embryonic membrane that is essential for the embryo's initial survival in many mammals. It also plays an important role in the production of proteins necessary for development. We studied proteins of the yolk sac in bovine embryos at up to 40 days of gestation. We examined the yolk sac of 17 bovine embryos at different gestational periods, measuring α-fetoprotein, α-1-an...

Puberty in South American Bos indicus (Zebu) cattle.

Puberty in Zebu heifers follows a pattern characterized by a decrease in the steroid feedback mechanism and an increase in LH concentration, which result in the first ovulation followed by a short estrous cycle and the onset of normal cycles thereafter. These events are similar to those observed in Bos taurus cattle but occur at a later age. The late onset of puberty is both genetic and environ...
