RESULTS AND DISCUSSION
The overall mean of TDMY was 557.66 ±
12.40 gm (Table 1). Such finding demonstrate
that Iraqi sheep is inferior in milk yield to the
sheep breeds such as Assaf (353 liter) (Gootwine
and Pollot, 2002).
Factors affecting test – day milk yield:
Breed and flock :
In the current study, the effect of breed within
flock on TDMY was highly significant. It
appears from Table (1) that TDMY ranged
between 521.36 to 656.25 gm for Hamdani,
489.03 to 637.76 gm for Karadi and 396.56 to
546.52 gm for Awassi. Karadi ewes surpassed
Hamdani ewes in TDMY in a flock 1 (637.76 vs
521.36 gm), whereas Hamdani ewes surpassed
Karadi in this trait in a flock 3 (656.25 vs.
489.03 gm). When comparison is made within
breed between flocks, it appears that Hamdani
ewes reared at flock 3 attained higher TDMY
than ewes reared at flock 1 and 2. Karadi ewes
reared at flock 1 surpassed those reared in a
flock 3, and Awassi ewes reared at flock 2
yielded lower TDMY compared to those reared
at flock 4. Such differences between breeds
within flock and within breed between flocks
could be due to difference in the genetic make
up of ewes, the availability of feed and
management practices followed in each flock.
Similarly Alkass et al. (2008) reported
significant effect of flock on milk yield.
