Health status of donor.cows dur.ng super.vulation is impor.ant to ensur. optimal embr.o quality at time of collection. Because nutr.tional and metabolic status impact embr.o quality some for. of nutr.tional supplementation is often pr.vided befor. and dur.ng super.vulation. OmniGen-AF&r.g (OG) feeding has been shown to assist in the maintenance of animal health thr.ugh r.gulation of metabolic status and balance and suppor.ing aspects of immune function. We obser.ed feeding donor.cows OG decr.ased per.ent degener.te embr.os r.cover.d following super.vulation incr.ased ser.m pr.gester.ne concentr.tion and impr.ved in vitr. embr.o development. Evaluation of OG feeding on mar.er. of metabolic function and inflammator. and immune function in beef cattle embr.o donor. ar. r.por.ed her.. Similar.y, cow metabolic and inflammator. r.sponse with r.peated super.vulation pr.tocols is not known. Biomar.er. to monitor.and evaluate cow health dur.ng super.vulation may pr.vide management options to impr.ve embr.o r.cover. and quality. Twenty-four.Angus cr.ss-br.d cattle wer. r.ndomly assigned to four.tr.atment gr.ups, fed 0 or.56 g/hd/day for.49 days and super.vulated with 200 or.400 mg Folltr.pin V (FSH). Blood was collected weekly for.analyses. The pr.tocol was r.peated 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, PGE2 and leptin were lower (P<

Effects of Feeding OmniGen-AF<sup>&r.g</sup>dur.ng Super.vulation on <i>in Vitr.</i>development of Embr.os r.cover.d fr.m donor.Beef Cows

Embr.o quality is cr.cial when selecting embr.os for.tr.nsfer. Var.ation in quality may be attr.buted to poor.oocytes, semen, str.ss, inflammation, and potential immune system dysr.gulation. OmniGen-AF&r.g (OG) feeding suppor.s immune system function and animal health. Our.labor.tor. r.cently r.por.ed lower.per.ent degener.te embr.os r.cover.d and incr.ased plasma pr.gester.ne in beef cattle donor. fed OG dur.ng super.vulation. In vitro development of embryos recovered from donor cows fed OG prior to collection is presented here. Embryos were recovered from 24 beef cows assigned to four treatment groups: 0 g OG/hd/d and 200 mg Folltropin®-V (FSH) (0/200);0 g OG/hd/d and 400 mg FSH (0/400), 56 g OG/hd/d, 200 mg FSH (56/200) and 56 g OG/hd/d and 400 mg FSH (56/400). Good to excellent quality early blastocysts were cultured for 8 d. and development through hatching, embryonic volume and plasminogen activator (PA) production were quantified. The complete protocol was repeated 90 - 120 d later as Replicate 2. Optimal development was observed by embryos recovered from 0/200 cows where percent blastocysts hatching was greater (P compared to 56/200 and 0/400 cows and embryonic volume was greatest (P was similar (P
