“…While in morulae, there were no differences among studied treatments. Snider et al (2019) used a registered nutritional supplement and the results indicated an improvement of embryo quality and a decrease of nontransferable embryos, with a supplementation period of 49 days, before embryo collection.…”

“…Cross-bred Angus cows (n = 24) were housed in a free stall barn in the Oregon State University Beef Cattle Center in Corvallis, OR with access to ad libitum grass hay and water. Cows were blocked for age and randomly assorted into four treatment groups (six cows per treatment) supplemented with 0 or 56 g/OG/ animal/day (completely mixed into a mixture of corn and molasses) and treatment with 200 or 400 mg Folltropin V® (FSH; Bioniche, Athens, GA) as previously described [22]. The duration of the supplementation was 49 d with a 28-d pre-feeding phase prior to the start of the superovulation protocol as previously described [22].…”

Health status of donor cows during superovulation is important to ensure optimal embryo quality at time of collection. Because nutritional and metabolic status impact embryo quality some form of nutritional supplementation is often provided before and during superovulation. OmniGen-AF® (OG) feeding has been shown to assist in the maintenance of animal health through regulation of metabolic status and balance and supporting aspects of immune function. We observed feeding donor cows OG decreased percent degenerate embryos recovered following superovulation increased serum progesterone concentration and improved in vitro embryo development. Evaluation of OG feeding on markers of metabolic function and inflammatory and immune function in beef cattle embryo donors are reported here. Similarly, cow metabolic and inflammatory response with repeated superovulation protocols is not known. Biomarkers to monitor and evaluate cow health during superovulation may provide management options to improve embryo recovery and quality. Twenty-four Angus cross-bred cattle were randomly assigned to four treatment groups, fed 0 or 56 g/hd/day for 49 days and superovulated with 200 or 400 mg Folltropin V (FSH). Blood was collected weekly for analyses. The protocol was repeated on all cows 90 -120 d later with cows reassigned to their original groups. No differences (P > 0.10) were observed due to OG feeding or FSH dose on metabolic and inflammatory markers. Replicate exerted a significant effect where serum concentration of albumin, IL1β, IL6, PGE 2 and leptin were lower (P < 0.05) in Replicate 1 compared to 2. There was also a similar pattern of change in several of the metabolic and
