Description :
Present study revealed that the genetic variants and their association with milk production traits in Tharparkar cattle of Madhya Pradesh at β casein gene (CSN1S2) gene locus. Correlation study of MY showed that there was a positive and highly significant correlation with Daily milk yield of both AA and AB genotype of β -casein gene in Tharparkar cow. Lactation length showed significantly negative correlation with milk yield(MY) and daily milk yield (DMY) trait in AA genotypes. Fat% showed highly significant but negative correlation with milk yield and daily milk yield whereas in AB genotype Fat% showed significantly negative correlation with Lactation length of Tharparkar cow. Milk protein of AA genotype showed significantly negative correlation with Fat % whereas Significant but positive correlation noticed between milk protein of both AA and AB genotype of Tharparkar cow and milk yield .Lactose of AA and AB genotype of Malvi showed highly significant and positive correlation with milk yield and milk protein. SNF of AB genotype in Tharparkar showed Highly significant and positive correlation with lactose milk protein and Milk yield . Milk density of AB genotype of Tharparkar cow showed highly significant and positive correlation with milk protein Lactose and SNF.
