Genetic evaluations of Holsteins in Colombia
Original data consisted of 31 777 records of progeny of 1442 sires. Unajusted means for milk yield (kg), days in milk, days dry, calving interval, days carried calf, and age at calving were 4281, 267, 88, 421, 145, and 36.6. Estimated total variance for first lactation milk yield by Henderson's method 3 was 1 385 436 kgø with sire and error variances accounting for 1.8 and 98.2 percent. Heritabilities for milk yield, lactation length, age at calving, and days carried calf were 0.07, 0.06, 2.59 and 0.01. First lactation sire values for milk ranged from 359 to - 340 kg with an average difference between sire of 12 kg. Sire values using all lactations ranged from 505 to - 286 kg with an average difference between sires of 13 kg. Rank correlation between all and first lactation evaluations was 0.77
