High-QualityFeedSupplement(HQFS)isafeedsupplementcontaininghighenergy,protein, minerals, and vitamins important for sheep reproduction. This study aimed to evaluate
theutilizationofHQFSinthecompleteofadultewesusingdriedipomeaaquaticastraw(DIAS).Fifteen Thin-Tailed Ewesaged two to three years with an average body weight of 32 ± 3.2 kg weredividedintothree treatmentgroups,withfiveewespertreatment.AllewesreceivedDIAS
and concentrate. The concentratecomprised soybean meal, corn meal, pollard, and copra meal,having TDN 70% and crude protein 17%. Treatment (T1) as the control group, ewes received 0%HQFS+60%concentrate+40%DIAS,T2:ewesreceived10%HQFS+50%concentrate
+ 40% DIAS, while T3: ewes received 20% HQFS + 40% concentrate + 40% DIAS. Ewe was keptinindividualpensof1x2meters.Feedwasgiven4%ofbodyweight/dayanddrinkingwater wasgivenadlibitum.Thetreatmentfeedwasforthreemonths,followingwhichbloodsamples,synchronization, and mating.The parameters of blood metabolites (glucose,urea,protein,cholesterol), profiles of estrogen and progesterone, oestrus characteristics (onset,intensity,
duration),pregnancyrate,andservice/conception(S/C)werestudied.Bothtreatmentgroups(T2,T3)havesignificantlylowerS/C(1.25vs.1,00)andpregnancyrates(80vs.100%)comparedto the control. Glucose and protein blood did not differ among the treatments, but cholesterol was highest in T2, while urea was lowest in T3.Substituting 10% HQFS significantly (P<0.05)increased estrogen (20.21 vs. 22.93 pg/ml) and progesterone (4.49 vs. 7.98 ng/ml) levels during theoestrusphasecomparedtothecontrol.UtilizationofHQFSsignificantly(P<0.05)
accelerated the onset of oestrus compared to the control (22 vs.28 hours and 23 vs. 28 hours),
