Exploration of Neuropeptide Y Gene Variants and its Association with Growth, First Lactation Reproduction and Production Traits in Sahiwal Cattle

摘要

Background: Neuropeptide Y (NPY), a 36-AA neurotransmitter involved in the control of appetite, feeding and energy homeostasis. The bovine NPY gene is located on chromosome 4 and consists of four exons. Earlier studies have reported that genes involved in feed intake regulation, energy production and energy regulation may affect different growth and production traits in cattle. Information associating NPY SNP to reproduction and production traits in dairy cattle is, however, limited. Hence, the present study was planned to explore SNPs in NPY gene and its possible association with reproduction and first lactation production traits in Sahiwal cattle.
