Study of milk production genes and their association with production traits in Rathi cattle

The study aimed to identify polymorphism of LEP, and STAT5A milk-producing genes their association with production traits in Rathi cattle. An overall 160 animals were selected from a population cattle Livestock Research Station, Rajasthan University Veterinary Animals Sciences, Bikaner (Rajasthan). phenotypic information on total milk yield, peak yield lactation length recorded the years 2012- 2018. Each animal’s sample (100 ml) was analysed for composition parameters. Genomic DNA extracted whole blood through spin column method analysis done. have been observed exon-3 (454 bp) LEP gene, intron 9-10 (224 intron-15-exon-16 (379 by PCR-SSCP revealed two types genotypic pattern. exon-7 (215 also showed three patterns. AB pattern AA significant effect yield. BB gene impact associated more fat % studied All these solids. different illustrated worth marker-assisted selection dairy Thus, present designed unmask relevant genetic factors responsible variation performance traits.
