Abstract excerpt
Leptin is an important regulator of fetal and placental growth. This study evaluated the association of single nucleotide polymorphisms (SNP) in the leptin gene with perinatal mortality (stillbirths and mortality within 24h of parturition) in 385 Holstein-Friesian heifers on 18 dairy farms in the United Kingdom. The 3 SNP evaluated were exon 2FB, UASMS1, and UASMS2. The mean age at first calving was 27.0+/-0.2...
