| description | <b>Aim:</b> In this study, it was aimed to determine the milk yield traits
together with environmental effects on different Holstein
breed reared in Kırşehir.<p>
<b>Materials and Methods:</b> The material used in the study was
comprised of the yield data of the pregnant Holstein heifers and
their calves imported from the USA and Estonia. In the study,
records of 263 cows (118 from USA, 145 from Estonia) for milk
production was analyzed. Totally 495 lactation records were
analyzed.<p>
<b>Results:</b> As for milk yield traits; the resuts of gestation lenght,
actual and 2 x 305 d milk yield, dry period length were 352±3.85
d, 8986±113 kg and 7004±67.4 kg, 61.6±0.6 d for all cows;
370.7±10.1 d, 9034±295 kg and 6738±161 kg, 60.78±1.37 d for
Estonian Holsteins; 296.1±15.1 d, 8383±441 kg and 7450±240
kg, 57.87±2.06 d for USA Holsteins. The origin of cows and age
at the begining of the lactation during lactation period (P<0.001
and P<0.05), lactation number with actual milk yield (P<0.01),
origin of cows and year of lactation with 2 x 305 d milk yield
(P<0.001 and P<0.05), lactation number and dry period length
were found significant (P<0.05).<p>
<b>Conclusion:</b> It can be concluded from this study that USA
Holsteins are preferable to Estonian Hosteins in terms of milk
production in intensive Holstein breeding in Kırsehir region of
Turkey. |
