Experimental design map. Dairy cows used for the Inbreeding Index (II) determination (ranges <2.5% and ≥2.5% to ≤5.0) from the total population analyzed (n = 385) by genomic tests (genotypic and phenotypic parameters). For genomic analysis, the sampling was carried out by using the Gene Max kit (TSU, ALLFLEX, Kalamazoo, MI, USA) and next a chip with 12,000 DNA markers (12K; Illumina Bovine SNP50 BeadChip, Clarifide–Zoetis, San Diego, CA, USA) was used for genotyping. The results have a ~70% reliability based on a panel of 50,000 (HD50K) genetic markers from the Animal Improvement Programs Laboratory (AIPL) (Zoetis–Clarifide, SanDiego, CA, USA). Genomic production values: MP305G: Milk Production at 305 days; MPFAT305G: Fat Production at 305 days; MPPROT305G: Protein Production at 305 days; PF305G: Percent of Fat at 305 days; PP305G: Percent of Protein at 305 days; SCCG: Somatic Cell Count; MRG: Mastitis Resistance. Genomic reproductive values: FIG: Fertility Index; HCRG: Nulliparous Cow Conception Rate; DPRG: Daughter Conception Rate; CCRG: Cow Conception Rate; DCEG: Daughter Calving Ease; MTRG: Resistance to Metritis; RPRG: Resistance to Placental Retention.
