Abstract

Artificial insemination using sex-sorted semen is employed to efficiently increase the number of female dairy calves born. Previous studies have determined that using sex-sorted semen is beneficial to improve the management, but the mechanism by which it increases cattle numbers through objective...

Abstract

The objectives of this cross-sectional study were to characterize reproductive management practices on Canadian dairy farms and describe differences based on regional and demographic factors. A questionnaire was offered to all licensed Canadian dairy producers and included 189 questions regarding...

Abstract

Little is known of the genetic variability in semen quality traits in cattle and their inter-relationships. The objective of the present study was to estimate genetic parameters for a range of semen quality measures. The data consisted of 35,573 ejaculates from 787 artificial insemination bulls of...

Abstract

The placenta is a major driver of prenatal growth and involved in programming of postnatal performance. We therefore determined placental and embryo-fetal ultrasonographic parameters in early pregnancy and their relationships with birth weight and postnatal weights in a Bos indicus-Bos taurus...

Abstract

The technological and agro ecological conditions of dairy production units in Mexico are highly heterogeneous. These conditions directly affect milk yield. An evaluation was done of how milk yield in family production units in the Tecamachalco basin, Puebla, Mexico, is influenced by a series of...

Abstract

Intense selection for a few desired traits has resulted in reduction of the effective population size (Ne) in most of the plant and livestock populations across the world. The objective of the research was to assess the impact of Ne on the genetic architecture of the population in a simulated data...

Abstract

Beef cattle numbers in Japan are decreasing with the loss of farmers. Improvement of productivity is necessary to allow the remaining farmers to stabilize cattle production and management. The calving-to-conception interval, which has increased in recent years, must be reduced. We made a system...

Abstract

We determined the risk factors for late embryonic mortality in dairy cows. We diagnosed pregnancy at 31 days and then confirmed the diagnosis at 45 days after artificial insemination (AI) via ultrasonography. The presence of an embryo with a heartbeat was the criterion for a positive pregnancy...
