The aims of this study were (1) to evaluate potential associations between genetic traits, postpartum phenotypes, cow factors, and vaginal discharge score (VDS); (2) investigate possible VDS, plasma progesterone (P4) after first service, reproductive performance. First- second-parity (n = 2,842) spring-calving lactating dairy cows from 35 herds enrolled. Farm visits performed every 2 wk during the period weekly breeding period. Cows that at 3 7 13 d artificial insemination (AI) examined....
Heifers typically have a reduced ovulation rate following gonadotrophin-releasing hormone (GnRH) application at initiation of CO-Synch + controlled internal drug release (CIDR) protocol. Thus, the objective present study was to determine whether increasing dose GnRH 5-day protocol in beef heifers would improve and therefore increase pregnancies per AI (P/AI). Angus yearling (n=299) five locations Ohio (United States) were randomised receive either 100µg (single; n=149) or 200µg (double;...
Ovarian follicle stimulation with exogenous FSH before ovum pickup (OPU) in Bos taurus females is a common practice to increase invitro embryo production (IVP). The optimal stimulatory period length for OPU-IVP, however, has not been definitively ascertained. objective of the present study, therefore, was determine effect superstimulatory treatment OPU on ovarian response and IVP Holstein heifers. Nonpregnant heifers (n=57) 13.8±0.2 months age moderate body condition score (3.0±0.1; scale 1...

Ovulatory response to the initial gonadotrophin-releasing hormone (GnRH) of CO-Synch protocol is affected by circulating progesterone (P4) and follicle size. In addition, heifers that ovulate GnRH treatment have greater fertility after AI. Thus, this study determined effect (1) presynchronization (Presynch) before a 6-day (2) [RCE1] on ovulatory response, oestrus expression, pregnancies per AI (P/AI) in beef heifers. Yearling (n=233) at three locations were randomly assigned 2×2 factorial...
Results from previous research indicate that induced pregnancy loss (IPL) on Day 36 of gestation in cattle resulted luteolysis by ∼45. The aim this study was to test the hypothesis IPL at 25, 35, or 55 days will result and whether interval between is positively associated with time treatment. Pregnant non-lactating beef cows were randomly assigned undergo IPL, consisting an intrauterine infusion 120mL hypertonic saline (7.2%), 25 (IPL25, n=15), 35 (IPL35, n=14), (IPL55, n=14). Corpus luteum...

Ovulatory response to the initial gonadotrophin-releasing hormone (GnRH) of CO-Synch protocol is affected by circulating progesterone (P4) and follicle size. In addition, heifers that ovulate GnRH treatment have greater fertility after AI. Thus, aim this study was assess effect (1) presynchronization (Presynch) before a 6-day (2) P4 device reuse (new vs. second use) on ovulatory response, oestrous expression, pregnancy per AI (P/AI) in beef heifers. Yearling (n=233) were randomly assigned...
