ABSTRACT
This experiment was carried out to determine feed intake and digestibility of grazing sheep on pasture. A total of 14 animals
randomly divided into two groups with seven animals each group were used in the
experiment. Digestibility of
pastures was determined using two types of markers—alkane (C32-C36) and chromium oxide.
Dry matter intake (DMI) was 717.22 g/d based on
chromium oxide method in the experiment, while according to alkane
method, DMI was 965.93 g/d and 1,051.07 g/d for C32 and C36, respectively. In conclusion, pastures met 74%-81% of crude protein
(CP) and 57%-61% of energy
requirements of lambs grazing on Yuzuncu Yil University pasture, who are mid-quality and 4-7
month-old with a 275 g/d expected daily gain. It was calculated that when 628-693
g/d of barley is given, both CP and metabolizable energy (ME) requirements of
animals can be met.
