4Abstract Flavonoid s are one of diet component of domestic livestock in wild life but thereis not enough information in area of importance that In the first step flavonoid scomponents FC isolated from propolis by ethanol extraction The extract analyzed fortotal flavonoid and phenolic components in the second experiment In third experiment In vitro trial was performed to investigate the importance of flavonoid s in the diet ofruminants The In vitro incubations by using batch rumen culture procedures wereconducted to study the effects of different levels of FC 140 70 35 and 17 g ml andalfalfa ethanol extract AE 44000 g ml on ruminal fermentation Rumen fluidcollected from two sheep fed diets contained DM basis 1 100 alfalfa 2 50 alfalfa 50 concentrate and 3 20 alfalfa 80 concentrate Presence of FC in theincubation reduced P 0 005 dry matter disappearance IVDMD NDF disappearance IVNDFD ADF disappearance IVADFD gas production ammonia N and protozoapopulation in diets 1 and 2 in comparison with controls but increased P 0 005 IVDMD in diet 3 as AE as Manner of ruminal fermentation is effect by flavonoid spresence in diet More research is essential to show importance of this component inruminant food In fourth experiment Using 3 diet 1 100 alfalfa 2 50 alfalfa 50 concentrate and 3 20 alfalfa 80 concentrate and a mixed culture of ruminalmicroorganisms have been studied the in vitro effects of flavonoid componentsaddition 140 70 35 and 17 g ml in compare with monensin 2 5 g ml on ruminalfermentation parameters IVDMD IVNDFD and IVADFD of ration 1 and 2 weredecreased significantly P 0 05 with all levels of FC and monensin in compared tocontrol but FC and monensin increased IVDMD in ration 3 Ammonia N concentrationand numbers of protozoa were decreased in a dose dependent manner of FC asmonensin as In the fifth experiment in a completely randomized design 20 Holsteincalves 7 2 d in four groups received 7 3 10 5 7 3 10 6 3 6 10 3 and 0 g Kg BW ofFC The results showed that using FC affected P 0 05 the weaning age and weightand also forage consumption after weaning but without any effect on growthparameters Serum IgG was not affected by FC At 6 wk control group had a higherconcentration of IgM than did treatment calves P 0 05 More research is essential toevaluate this component in calf s nutrition
