Fixed-time artificial insemination in beef cattle
BACKGROUND The study was designed to test the effect of fixed-time artificial insemination (fixed-AI) after the slightly modified Ovsynch protocol on the pregnancy rate in beef cattle in Finnish field conditions. The modification was aimed to optimize the number of offsprings per AI dose. METHODS Ninety Charolais cows and heifers were entered into the program an average of 1.8 times. Thus, 16...
متن کاملDifferences in Mating between a Boar, Traditional Artificial Insemination, and Post Cervical Insemination
As populations around the globe are growing the demand for pork protein in the human diet is increasing. Technologies utilized in 1990s such as artificial insemination have improved our capabilities to produce leaner carcasses. Utilizing superior genetics and breeding techniques as tools to improve growth rates, feed efficiency, and carcass quality is imperative for the swine industry to succes...
متن کاملEffect of boar exposure at time of insemination on factors influencing fertility in gilts.
The effect of boar exposure during artificial insemination (AI) on semen backflow, fertilization, and embryo quality was evaluated. Gilts (approximately 170 d) were induced into estrus with PG600, and ovulation was synchronized using hCG 72 h later. Estrus detection was initiated after PG600 and continued at 12-h intervals. At estrus, gilts were allotted to receive boar exposure (BE, n = 20) or...
متن کاملOvulation induction in rabbit does submitted to artificial insemination by adding buserelin to the seminal dose.
This study was aimed at determining if a GnRH analogue, buserelin, could be used for ovulation induction in rabbit does submitted to artificial insemination (AI) by intravaginal administration, by adding the hormone to the seminal dose. In a first experiment, 39 secondiparous experimental does (Hyplus strain PS19, Grimaud Frères, France, of about 30 weeks of age) were divided into 3 groups of 1...
متن کاملUse of boar spermatozoa for artificial insemination. II. Fertilizing capacity of fresh and frozen spermatozoa in gilts inseminated either at a fixed time or according to Walsmeta readings.
A fertility trial was conducted comparing two methods of defining the optimum time to inseminate frozen boar semen. One hundred sixty-four gilts were inseminated, one-half at a fixed insemination time of 32 to 34 h after calculated onset of estrus and the remainder were inseminated on the basis of changes in the vaginal mucosal electrical resistance. Inseminations were made when the instrument ...
