Beef and dairy productivity depends directly on the reproductive efficiency genetic gain of herd, which can be related to appropriate use biotechnologies, such as timed artificial insemination (TAI).When considering variations in synchronizations protocols, longer or shorter periods progesterone (P4) device treatment could provide benefits fertility.However, our studies evidenced that protocols with six (J-synch), seven, eight nine days P4 had similar pregnancy per AI (P/AI).In cyclic cows,...
Abstract Background Undiagnosed cases of hepatitis C virus (HCV) infection result in significant morbidity and mortality, further transmission, increased public health costs. Testing emergency departments (EDs) is an opportunity to expand HCV screening. The goal this project was increase the proportion eligible patients screened for urban areas. Methods An opportunistic automated screening program implemented EDs 4 hospitals Spain Portugal at different periods between 2018 2023. prevalence...
Ovulation synchronization protocols are well established in beef and dairy cows. However, the protocol response rate is around 70-90%. In cows, factors such as inadequate nutrition calf presence negatively impact of progesterone (P4)/estradiol-based ovulation by interfering with GnRH release consequently reducing LH pulsatility final follicular development. based on prostaglandin (Ovsynch) most widely used world. efficiency Ovsynch dependent a large follicle at time administration first...
Abstract This study evaluated the association between plasma anti‐Mullerian hormone (AMH) concentration and fertility in Nelore ( Bos indicus ) heifers submitted to timed artificial insemination (TAI). At onset of synchronization protocol, n = 289) received a subcutaneous P4 ear implant (3 mg) 2 mg oestradiol benzoate. Eight days later, was removed 0.5 cypionate, prostaglandin (0.265 mg, i.m.) equine chorionic gonadotropin (300 UI, administered, TAI performed 48 hr after removal. Ovarian...
Abstract This study evaluated the efficacy of administration different doses equine chorionic gonadotropin (eCG; 0 IU, 200 or 300 IU) at time progesterone device removal in 2‐year‐old Nelore ( Bos indicus ) heifers synchronized for fixed‐timed artificial insemination (FTAI). On day (D0), a total 398 received 2 mg oestradiol benzoate i . m ., 0.53 cloprostenol and an eight‐day previously used (second use) intravaginal containing 1 g (P4). Eight days later (D8), simultaneous with P4 removal,...
Reproductive efficiency has a major impact on profitability of dairy farms. Pregnancy loss in cattle is one the impediments for adequate reproductive performance. The aim present study was to evaluate factors associated with pregnancy between 30 and 60 days gestation high-producing repeat-breeder (>4 services) Holstein cows submitted embryo transfer (ET). A retrospective analysis performed using data from 1 commercial farm, located Descalvado, Brazil (22°01′27″S; 47°53′19″L). Overall,...
