Information on 762 reproductive records on Saanen\u2009\u00d7\u2009Beetal (S \u00d7 B) goats reared for approximately five decades was collected from ICAR\u2010National Dairy Research Institute, Karnal, Haryana (1973\u20132020). For genetic analysis, single\u2010trait and multiple\u2010trait animal models were used. Gibbs sampler for animal model (GSAM) approach was used for estimating (co)variance components of reproductive traits. Six different single\u2010trait animal models (with or without maternal and environmental effects) were used and the deviance information criterion (DIC) determined the best model. The least squares mean for age at first service (AFS), age at first kidding (AFK), service period (SP), dry period (DP), gestation length (GL), kidding interval (KI), litter weight (LW), number of kids born (NKB) and number of female kids born (NFKB) in first parity were 526.99\u2009\u00b1\u20094.86, 662.96\u2009\u00b1\u20095.03, 219.11\u2009\u00b1\u20096.25, 109.38\u2009\u00b1\u20096.00, 150.48\u2009\u00b1\u20090.27, 356.63\u2009\u00b1\u20094.80\u2009days, 3.87\u2009\u00b1\u20090.05\u2009kg, 1.27\u2009\u00b1\u20090.02 and 0.67\u2009\u00b1\u20090.03, respectively. Lower heritability estimates for these reproductive traits revealed a sparse scope for genetic improvement. Multivariate analysis using Model 1 was carried out to evaluate the genetic and phenotypic correlation of these nine reproductive traits. The genetic correlation of DP and SP was negatively with LW, NKB and NFKB, which is favourable as reduction in SP and DP can improve these economically important traits through indirect selection. Consistent efforts towards genetic improvement of these goat flock poses a promising future for meat industry owing to high prolificacy and good reproductive potential in this flock.<\/jats:p>","DOI":"10.1111\/rda.14669","type":"journal-article","created":{"date-parts":[[2024,7,15]],"date-time":"2024-07-15T08:15:46Z","timestamp":1721031346000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Assessing genetic parameters for first parity reproductive traits for early selection in Saanen\u2009\u00d7\u2009Beetal goats of India"],"prefix":"10.1111","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5154-5719","authenticated-orcid":false,"given":"Shweta","family":"Sahoo","sequence":"first","affiliation":[{"name":"Department of Animal Genetics and Breeding ICAR\u2010National Dairy Research Institute  Karnal Haryana India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9163-3724","authenticated-orcid":false,"given":"Rani","family":"Alex","sequence":"additional","affiliation":[{"name":"Department of Animal Genetics and Breeding ICAR\u2010National Dairy Research Institute  Karnal Haryana India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7581-4939","authenticated-orcid":false,"given":"Vikas","family":"Vohra","sequence":"additional","affiliation":[{"name":"Department of Animal Genetics and Breeding ICAR\u2010National Dairy Research Institute  Karnal Haryana India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1711-6582","authenticated-orcid":false,"given":"Sabyasachi","family":"Mukherjee","sequence":"additional","affiliation":[{"name":"Department of Animal Genetics and Breeding ICAR\u2010National Dairy Research Institute  Karnal Haryana India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6535-7818","authenticated-orcid":false,"given":"Gopal R.","family":"Gowane","sequence":"additional","affiliation":[{"name":"Department of Animal Genetics and Breeding ICAR\u2010National Dairy Research Institute  Karnal Haryana India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,7,15]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.5424\/sjar\/2018162\u201012604"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.smallrumres.2005.09.033"},{"issue":"5","key":"e_1_2_11_4_1","first-page":"441","article-title":"Operationalizing the pro\u2010poor potential of livestock: Issues and strategies","volume":"82","author":"Birthal P.
