Genetic gains comparisons were also estimated. A total of 53,683 data of Nelore animals born between 1990 and 2006, obtained from the livestock archive of Agropecu\u00e1ria Jacarezinho Ltda. (Valpara\u00edso, S\u00e3o Paulo, Brazil), were analyzed. Two-trait analysis provided heritability estimates of 0.35 \u00b1 0.08, 0.40 \u00b1 0.04, 0.37 \u00b1 0.03, 0.21 \u00b1 0.01, 0.55 \u00b1 0.03, and 0.17 \u00b1 0.03 for SC12, SC15, SC18, AFC, HP, and HR, respectively. The genetic correlations between scrotal circumference and AFC, HP, and HR were \u20130.42 \u00b1 0.12, 0.43 \u00b1 0.13, and \u20130.13 \u00b1 0.17, respectively, for SC12; \u20130.25 \u00b1 0.07, 0.26 \u00b1 0.07, and \u20130.11 \u00b1 0.10, respectively, for SC15; and \u20130.22 \u00b1 0.06, 0.39 \u00b1 0.06, and 0.11 \u00b1 0.09, respectively, for SC18. The direct selection response for HP was 0.12%, but when HP is indirectly selected based on the scrotal circumferences, the gains on these correlated responses were higher (0.16, 0.16, and 0.22%) for selection based on SC12, SC15, and SC18, respectively. These findings suggest that the selection of animals for larger scrotal circumference, particularly at 12 mo of age, should result in higher rates of HP and younger AFC of Nelore females.<\/jats:p>","DOI":"10.2527\/jas.2014-8817","type":"journal-article","created":{"date-parts":[[2015,5,8]],"date-time":"2015-05-08T12:11:48Z","timestamp":1431087108000},"page":"2706-2713","source":"Crossref","is-referenced-by-count":40,"title":["Genetic associations between scrotal circumference and female reproductive traits in Nelore cattle"],"prefix":"10.1093","volume":"93","author":[{"given":"A.
