The mean (&amp;plusmn; SD) daily milk yields were 1.7 &amp;plusmn; 0.6, 6.3 &amp;plusmn; 1.2 and 5.1 &amp;plusmn; 1.0 litres, respectively. The lactation lengths, ages at puberty, gestation lengths, calving intervals, numbers of services per conception, intervals between calving and first oestrus were 217.9 &amp;plusmn; 18.7, 253.8 &amp;plusmn; 21.9, 240.8 &amp;plusmn; 15.7 days; 27.4 &amp;plusmn; 2.7, 23.9 &amp;plusmn; 2.0, 26.2 &amp;plusmn; 2.4 months; 277.4 &amp;plusmn; 4.2, 278.3 &amp;plusmn; 4.2, 278.3 &amp;plusmn; 4.0 days; 494.8 &amp;plusmn; 27.3, 487.5 &amp;plusmn; 17.4, 493.3 &amp;plusmn; 16.2 days; 1.3 &amp;plusmn; 0.5, 1.7 &amp;plusmn; 0.6, 1.6 &amp;plusmn; 0.5; 145.6 &amp;plusmn; 27.4, 166.8 &amp;plusmn; 33.0 and 170.5 &amp;plusmn; 34.9 days, respectively. Daily milk yield and lactation length were significantly (p&amp;lt;0.01) better for cross-bred cows than for &lt;em&gt;Desi&lt;/em&gt;, and age at puberty was significantly (p&amp;lt;0.01) better for Friesian-cross cows than for &lt;em&gt;Desi&lt;/em&gt;, while number of services per pregnancy and onset of post partum oestrus were significantly (p&amp;lt;0.01) better for &lt;em&gt;Desi &lt;/em&gt;than for cross-bred cows. There were no significant differences in gestation length and calving interval. It is suggested that the overall productive and reproductive performance of Friesian &amp;times; &lt;em&gt;Desi &lt;/em&gt;and Sahiwal &amp;times; &lt;em&gt;Desi &lt;/em&gt;cows were better than those of &lt;em&gt;Desi &lt;/em&gt;cows.&lt;/p&gt; &lt;p&gt;DOI: 10.3329/bvet.v25i2.4620&lt;/p&gt; &lt;p&gt;&lt;em&gt;Bangl. vet&lt;/em&gt;. 2008.
