To study the effect of feeding halophytic plants on the composition and quality of Barki ewes milk. Forty Barki ewes 3-4 years old with average live body weight of (45.2 ± 0.47 kg) were divided into lower similar groups (ten lactating ewes in every  group ).The first group (control) fed on the rationconsisted of concentrate  feed mixture (CFM),rice straw plus Berseem Hay (BH) at levels of 60:10:30 % respectively.Berseem Hay (BH) for the other three group's was replaced by leaves and stems of (Acacia, Atriplex and Cassava)  for 2^nd, 3^rd and 4^th groups , respectively. Ewes were suckled from delivery until weaning kids. Milk samples were collected  for each group  from second week till to seventh week. Results  showed that,  the milkyield  increased in the  experimental groups than in control, either  weekly or after 7 weeks  of  lactating  period , with the  exception of ( Atriplex )  treatment . Cassava treatment had  the  maximum  total  milk  yields  all over  the  suckling  period  , followed  by  Acacia  , Hay  and  Atriplex  treatments ,respectively.The highest content of milk fat was noticedat seventh week for  control  group  (BH) , while Cassava group scored the lowest one . Protein content was higher  in Acacia and Atriplex than in Hay and Cassava at all lactation weeks.Lactose content was the highest inAcacia group milk , and the lowest in Cassava group ,  at seventh week . Total solids ( TS ) content was lower in Cassava than in the  other groups during the 1^st six weeks of lactation.The highest value of TS was  noticed   in Hay group , at the seventh lactation week.Atriplex group had the highest ash content at seventh week. Acidity  values  of milk among  the  four groups ranged  betwee0.16  to 0,20% ,density  values  were  found  lower  in  control  group  than in  the other groups  along  the  lactation   period .  Frozen points of milk of all groups were found approximately similar of– 0.61, after 7 weeks.  Macro-elements ; calcium  ,  phosphorus , sodium  and  potassium of  ( Atriplex ) had the highest contentsat  7^thweek, while  the lowest were obtained in control (BH) group  . Micro elements;  ferric , manganese ,  magnesium  , zinc  and copper  were  higher  in  some  treatments , and  lower  in the  others  , during  the  lactating  period . Anti-oxidants compunds were determined in milk , curd and whey of each group separately.Average of  total anti-oxidants values of phenols,flavonoids, carotenoids and tannins were found  higher in milk of groups fed on  the halophytic plants, and   the highest value  was  found in (Cassava)  group milk, while  the lowest   was in  control group.Control groupmilk curd contained the lowest total anti-oxidant  compounds, compared with the  other  groups fed on the halophytic stems and leaves. Cassava group milk curd had the highest values. Total  anti-oxidant  compounds  in  whey  of   the  four  groups  were found  lower than  that  of the   milk  or  curd  ,and  the highest value  was in Cassava group, while  the lowest value was  found with control group. Generally ,it was found  that milk yield  of   control  group  was    lower   than  the  yield  of the  other groups , with the  exception  of  Atriplex group. Gross  composition  of  milk groups Cassava , Acacia and  Atriplex was  superior than  the  other one  of  control  group . Similar trend was noticed in macro-elements.  Values of micro-elements varied among the four groups. Concerning  milk  anti-oxidants compounds  ,  control group  recorded  the  lowest  values , and  Cassava  group had  the  highest  values.
