The descriptive statistical analysis was performed using the R package. Genetic parameters were estimated using BLUPF90 by a single-trait animal model. A selection index was constructed using adjusted breeding values multiplied by variable economic weightage for each trait. \n&lt;b&gt;Results: &lt;\/b&gt;Genotype had significant effects on the investigated semen quality attributes (&lt;i&gt;p&lt;\/i&gt; &lt; 0.05), where 75%HF \u00d7 25%L and 62.5%HF \u00d7 37.5%L crossbred genotypes both differed significantly from 50%HF \u00d7 50%L crossbreds (&lt;i&gt;p&lt;\/i&gt; &lt; 0.05). In general, better productive and reproductive performances were found with the progression of HF inheritance. Daughters of 75%HF \u00d7 25%L crossbred bulls showed the highest average performance in birth weight (27.20 \u00b1 0.09 kg), daily milk yield (8.55 \u00b1 0.06 l), peak milk yield (10.44 \u00b1 0.07 l), and lactation length (233.53 \u00b1 0.85 days). The study investigated variance components of eight productive and reproductive traits such as the birth weight of calf, age at first conception, service per conception, daily milk yield, peak milk yield, lactation length, and calving interval where estimated heritability ranged from 0.09 to 0.32. Genetic correlations among the considered traits were found to be mostly weak. Among the top 20%, breeding bulls belonged to 75%HF \u00d7 25%L and 62.5%HF \u00d7 37.5%L crossbred groups. \n&lt;b&gt;Conclusion:&lt;\/b&gt; This study provides insightful information on the genetic evaluation of different graded bulls that could be the basis for the proven crossbred breeding bulls\u2019 selection process at CCBDF.<\/jats:p>","DOI":"10.5455\/javar.2025.l901","type":"journal-article","created":{"date-parts":[[2025,8,1]],"date-time":"2025-08-01T23:30:41Z","timestamp":1754091041000},"page":"334","source":"Crossref","is-referenced-by-count":0,"title":["Genetic evaluation of different graded Holstein Friesian \u00d7 Local (HF \u00d7 L) crossbred breeding bulls of Bangladesh"],"prefix":"10.5455","volume":"12","author":[{"given":"Md.","family":"Hridoy","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sadia","family":"Siddiqua","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Doo","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yeong","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Md.","family":"Khoda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monira","family":"Mou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abul","family":"Bhuiyan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad","family":"Bhuiyan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3407","container-title":["Journal of Advanced Veterinary and Animal Research"],"original-title":[],"link":[{"URL":"https:\/\/www.bibliomed.org\/fulltextpdf.php?mno=235072","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T18:02:42Z","timestamp":1791482562000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.bibliomed.org\/?mno=235072"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.5455\/javar.2025.l901","relation":{},"ISSN":["2311-7710"],"issn-type":[{"value":"2311-7710","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025]]}}}
