The objective of this observational study was to describe the association between lag time from calving to first milking for colostrum harvest. Colostrum samples from primiparous and multiparous Holstein cows (n = 640) from a single herd milking approximately 5,200 cows 3 times daily in a 100-stall rotary parlor were used in this prospective cohort study. Calves were removed immediately after calving and not allowed to suckle their dam.

Background: Determination of the estradiol hormone in urine is crucial for evaluating congenital adrenal hyperplasia, certain hormone-producing ovarian tumors, polycystic ovary syndrome, liver disease, pregnancy, and infertility. On the other hand, steroid hormones can have destructive effects on the environment, animals, and the endocrine system of humans. Consequently, accurately measuring this hormone's concentration in trace amounts is essential for environmental safety and human health.

Rickettsia spp. are Gram-negative obligate intracellular bacteria, with Rickettsia africae being transmitted by Amblyomma ticks and posing a zoonotic risk. The status of diseases like rickettsiosis is largely unknown in Somalia.

Pooling samples allows for efficient and cost-effective surveillance of endemic pathogens, enabling broader testing coverage and reducing diagnostic costs. Pooling swine samples for influenza A virus surveillance without negatively impacting sensitivity would depend on the sample type, cycle threshold (Ct value), and dilution level. Therefore, this study aimed to compare the probability of IAV reverse transcription real-time polymerase chain reaction (RT-rtPCR) detection at different pooling levels in family oral fluids, udder wipes, and nasal wipes obtained from an endemic swine breeding herd.

XXXXX recently added brain to its fentanyl analog testing method for 14 analogs (fluoroisobutyryl fentanyl, acetyl fentanyl, acryl fentanyl, alfentanil, butyryl fentanyl, carfentanil, fentanyl, para-fluorofentanyl, furanyl fentanyl, methoxyacetyl fentanyl, norcarfentanil, norfentanyl, sufentanil, and valeryl fentanyl) and 3 U-series drugs (U-47700, U-48800, and U-49900). Brain is a protected and isolated organ with lower metabolic activity than other tissues, which can assist in interpreting results and preserving parent drug. Limited publications testing brain samples for fentanyl and fentanyl analogs exist and none describe homogenate stability for these analytes.
