The aim of this study was to investigate
the effects of milking frequency reduction and dietary
lipid supplementation on intake, BW, and milk yield
and composition in high yielding dairy ewes. Ten lactating
Assaf ewes were allocated into 2 experimental
groups (n = 5). Ewes were fed alfalfa hay ad libitum
and 34 g·kg–1 of BW of a concentrate feed with either
0 (Control group) or 43 g of sunfl ower oil·kg–1 of DM
(SO group). The experiment lasted 63 d and consisted
of 3 periods. During Period 1 (from d 1 to 21), ewes
were milked twice a day. During Period 2 (from d 22 to
49), ewes were unilaterally milked, so that each gland of
each ewe was milked either once or twice daily. During
Period 3 (from d 50 to the end of the experiment), both
udder halves were again milked twice daily. Intake, BW,
and milk composition were controlled weekly and milk
production from each half udder was recorded twice a
week. Total DM intake, BW, and milk yield in Period
1 were not signifi cantly (P > 0.10) affected by dietary
treatments. Milk yield tended to be increased in the ewes
fed the SO diet in periods 2 (P = 0.093) and 3 (P = 0.067).
Oil supplementation (SO diet) signifi cantly (P < 0.05)
decreased milk protein and total solids concentrations in
the 3 experimental periods and fat content in Period 3
