Association of polymorphism at intron 2 of FABP3 Gene with milk production traits in Sahiwal and Karan Fries cattle

摘要

PCR-RFLP analysis of PCR products were carried out using Aci I/SSi I for 100 Sahiwal and 115 Karan Fries cattle. In Sahiwal cattle and Karan Fries cattle, 438bp has three genotypes AA (438), AB (438+299+139 bp) and BB (299+139 bp). In Sahiwal cattle these genotypes are highly significant for FL305DPY but in Karan Fries cattle these genotypes are highly significant for FL305DMY, FLTMY, FL305DFY and FL305DPY. In Sahiwal cattle, mean +/- SE of AA genotype for FL305DMY, FLTMY, FL305DFY, FL305DSNFY, FL305DPY were 1809.90 +/- 15.7 kg, 2029.4 +/- 15.6 kg, 99.90 +/- 0.66 kg, 154.87 +/- 0.17 kg and 44.81 +/- 0.06 kg, respectively and for AB genotype were 1800.76 +/- 9.48 kg, 1993.99 +/- 9.42 kg, 100.54 +/- 0.39 kg, 154.79 +/- 0.10 kg, 43.99 +/- 0.04 kg, respectively and for BB genotype were 1830.0 +/- 14.10 kg, 2032.80 +/- 14.0 kg, 100.24 +/- 0.59 kg, 155.11 +/- 0.15 kg, 42.98 +/- 0.05 kg, respectively. Heterozygous AB genotype was found to be superior for, FL305DFY trait. AA genotype was significantly superior for FL305DPY traits whereas BB genotype was found to be superior for FL305DMY, FLTMY, FL305DSNFY. In Karan Fries cattle, the mean +/- SE of AA genotype for FL305DMY, FLTMY, FL305DFY, FL305DSNFY, FL305DPY were 3442.17 +/- 8.39 kg, 4461.93 +/- 8.39 kg, 124.96 +/- 7.20 kg, 277.35 +/- 0.08 kg and 112.51 +/- 0.08 kg, respectively and for AB genotype were 3572.69 +/- 5.93 kg, 4592.45 +/- 5.93 kg, 140.17 +/- 5.09 kg, 278.60 +/- 0.06 kg, 113.91 +/- 0.05 kg, respectively and for BB genotypes were 3502.41 +/- 9.19 kg, 4522.17 +/- 9.19 kg, 136.91 +/- 7.89 kg, 277.93 +/- 0.09 kg, 113.19 +/- 0.08 kg, respectively.
