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 کاملA Comparison of Transcervical and Laparoscopic Intrauterine Artificial Insemination Techniques on Reproductive Performance of Ewes
In all domestic species, acceptable pregnancy rates with frozen-thawed semen are only achievable with intrauterine insemination. Unlike the cow and the goat, the cervix of the ewe is a formidable barrier to penetration for transcervical intrauterine insemination not only due to the physical size of the canal and a narrow luminal diameter (even at estrus), but also due to it’s caudally facing, e...

متن کاملArtificial Insemination
A GROUP of dairymen in New Jersey organized in 1938 the first cooperative in the United States for the artificial insemination of their cows. This method of serving females without natural mating has since become one of the most significant programs for livestock improvement in the history of American agriculture. A great deal of research has been done on all phases. A basic contribution was th...
متن کاملArtificial Insemination
[2] Artificial insemination is a relatively simple medical procedure by which semen obtained by masturbation is deposited by means of a syringe in or near the cervix of the woman's uterus. Artificial insemination is of two basic types: homologous insemination, when the semen is obtained from the husband (AIH); and heterologous insemination, when the semen is obtained from a donor (AID). AIH is ...
