The Effect Of Prostaglandin Inhibitor On Pregnancy Rates Of Heifer Embryo Transfer Recipients, Jared William Mcnaughtan
The Effect Of Prostaglandin Inhibitor On Pregnancy Rates Of Heifer Embryo Transfer Recipients, Jared William Mcnaughtan
Theses and Dissertations
Manipulation of the reproductive tract results in increased levels of prostaglandin, which may, in turn, reduce pregnancy rates in embryo recipients. Administration of a prostaglandin inhibitor prior to embryo transfer improves pregnancy rates in cows. Embryo transfer into heifers is more difficult and often requires additional manipulation of the uterus. This study was designed to determine whether administration of the prostaglandin inhibitor, flunixin meglumine, immediately prior to embryo transfer increases pregnancy rates in heifers. Heifers (n=466) were divided into two equal groups based on BCS (range=6-7) and weight (range=256-455). Estrus was synchronized in heifers by giving two injections of prostaglandin …
Evaluation Of Agronomic Performance Of Forage Grasses In Tiahuanaco, Justiniano Mamani Condori
Evaluation Of Agronomic Performance Of Forage Grasses In Tiahuanaco, Justiniano Mamani Condori
Theses and Dissertations
Most families in the area of Tiahuanaco, Bolivia participate in livestock production, mainly cattle breeding. The primary feed sources for livestock in this area are native grasses, barley, and, to a smaller degree, oats. These grasses have low yield because of climate and soil conditions. This area does not have enough forage, especially during the dry season, and the animals are not regularly fed during the year. Consequently, animal production is low. This research was conducted during 2001 and 2002 at the Bolivian Catholic University campus, Farmer’s Academic Unit of Tiahuanaco, Ingavi Province, La Paz, Bolivia. Study site locations were …
