| Summary: | <b>Aim: </b>This study was conducted to investigate the characteristics of milk yield
and reproductive performance of Hair goats raised under the extensive condition
in Konya and Karaman regions of Turkey.<p>
<b>Materials and Methods: </b>For this purpose, 383 and 58044 records were
analyzed for milk yield and reproductive performance, respectively. Six measurements
were performed with 30 days intervals for evaluating of the goats?
milk yield characteristics. Individual lactation milk yield was calculated
as area under the lactation curve. General linear model involving factors of
region, farm, goat age and birth type were used for milk yield characteristics
in statistical analyses, Chi square test was employed for evaluating the reproductive
performance.<p>
<b>Results: </b>The mean of the lactation period, daily and lactation milk yield, were
found as 171.0 days, 753.7 mL, and 128.9 L, respectively. Despite the fact that
the effect of birth type factor on all three characteristics was not significant
(p>0.05), it was found that the region and farm factors had a significant effect
on all three characteristics (p<0.001). Goat age factor had a significant effect
on daily milk yield and lactation milk yield (p<0.001). Birth rate, twin rate,
and kidding rate of goats were found as 81%, 9%, and 0.88, respectively. In
reproductive performance, the significant difference between two regions and
also significant differences among years in each regions were seen (p<0.01).<p>
<b>Conclusion:</b> In conclusion, the parameters of the lactation milk yield and lactation
period in Hair goats raised in both regions were seen in higher value
than the levels reported previously in the literature. |
