Abstract Fall-calving Angus-based cows (n = 170 unique cows; 400 calving records during three years) were used to determine prolactin (Prl) genotype and haplotype effects on phenotypic traits. Genomic DNA, from buffy coat, was genotyped at three Prl SNP sites (C1286T, A1134T, and G8398A). Traits of interest were: pre-breeding body condition score (BCS) and weight, Julian calving date, calf birth weight, cow weight and BCS at weaning, calf weaning weight, adjusted 205-day weight and cow efficiency. Hair coat scores were determined each year in May, June, and July. Heterozygous cows at SNP C1286T had a lower (P 0.10) phenotypic traits. Six haplotypes were identified: CAG (n = 107), TAA (n = 173), CTG (n = 50), TTA (n = 32), TAG (n = 50), and TTG (n = 37); n represents total number of records for that haplotype during 3-year study. Calving percentage for CAG cows was greater (P
