Cholesterol deficiency (CD) in Holstein cattle, caused by a loss-of-function mutation in the A total of 188 cows were classified by lactation: 1 The heterozygous CD genotype was identified in 17.02% of the population, with wild-type and mutant allele frequencies of 0.91 and 0.09, respectively. Non-carriers showed marginally higher fat, protein, and cholesterol levels, with a statistically significant difference in fat content (p = 0.04). When stratified by lactation, significant differences were observed for fat content in the 1 This study confirms the presence of the CD-associated Show less
