Abstract

Cattle that are not pregnant to first fixed-time artificial insemination (TAI) may be resynchronized for a second TAI if they are found nonpregnant at pregnancy diagnosis. The specific interval between first and second TAI ranges from 4 to 8 wk. The selected interval depends on the available method ...

Abstract

In dairy cattle, 4 important recessive hereditary diseases exist: complex vertebral malformation (CVM), bovine leukocyte adhesion deficiency (BLAD), citrullinemia (CTLN), and deficiency of uridine monophosphate synthase (DUMPS). Holstein Associations in developed countries have established...

Abstract

In cows, interferon-tau (IFNT) regulates maternal recognition around days 15-19 after artificial insemination (AI). The present study hypothesized that if key target genes of IFNT are clearly upregulated in earlier stages of pregnancy, these genes could be use as indices of future pregnancy in...

Abstract

The objectives of the current study were to investigate the efficacy of PGF as a therapy to reduce the prevalence of subclinical endometritis and improve pregnancy per artificial insemination (P/AI) in cows subjected to a timed artificial insemination (AI) program. A total of 1,342 lactating...

Abstract

The objectives of the current study were to evaluate the effects of supplemental progesterone after artificial insemination (AI) on expression of IFN-stimulated genes (ISG) in blood leukocytes and fertility in lactating dairy cows. Weekly cohorts of Holstein cows were blocked by parity (575...

Abstract

This study aimed to investigate mRNA transcriptions of interferon stimulated genes ISG15 and OAS1 in the peripheral blood of Chinese Holstein dairy cows during early pregnancy, by which we hope to provide an insight into their applications in bovine early pregnancy diagnosis. A total of 27 heifers...

AbstractFull Text

This study was undertaken to investigate the influence of magnetic water treatment on testis dimensions, scrotal circumference and levels of blood parameters for Holstein bulls born in Iraq. Sixteen Holstein bulls born in Iraq were selected on basis of age 17-19 months (8 bulls) and 29-32 months (8 ...

Abstract

Our objective was to evaluate the effects of temporarily decreasing progesterone (P4) after timed artificial insemination (TAI) on embryonic growth in dairy cows. Lactating Holstein cows (n=80) were submitted to a Double-Ovsynch protocol for first TAI and were assigned randomly to receive 12.5 mg...
