“…The number of observed alleles per locus had ranged from 4 (ILSTS11) to 12 (INRA23 and TGLA122), while the expected number of alleles ranged from 2.701(ETH3) to 6.485(CSSM66), with mean values of 8.095±0.47 and 4.388±0.24 respectively (Table2 and Figure2). The values observed in the study were in agreement with earlier reports in various Holstein Freisian populations1,7 . The Indian and Chinese HF populations were found to have an average of 10.5 across 12 loci and 8.35 across 17 loci respectively; with the number of alleles per locus varying from 7 (ETH225 and ETH3) to 16 (INRA23) in the former and 6 (TGLA126) to 16 (TGLA122) in the latter.…”

“…Parentage testing in cattle is an important aspect today to implement efficient breeding programs by selective reproduction through proven bulls. Failure to record the correct parentage can cause bias in sire evaluation, by introducing errors in estimation of heritabilities and breeding values 1 . Parentage testing relies on the principle that an individual will inherit one copy of its genes from its mother and other from its father 2 .…”

A study was aimed to evaluate a set of polymorphic microsatellite markers for their efficiency in testing parentage in Jersey crossbred cattle available in Tamil Nadu. The objective of validation was based on the criteria such as polymorphism information content, various genetic diversity parameters and the ability of markers to exclude the wrong parent. A total of 21 microsatellite markers were included to verify the parentage in 24 Jersey crossbred trios (comprising 24 dams, 24 progenies and 2 sires). The microsatellite loci were amplified using fluorescently labelled primers by multiplex PCR and fragment analysis was done through capillary electrophoresis using automated DNA analyzer. Statistical analyses were done using Pop gene version 1.31, CERVUS 3.0.7 and GENALEX 6.503 software programs. The number of alleles for the markers utilized in the study ranged from 4 (ILSTS11) to 12 (INRA23 and TGLA122) with an overall mean of 8.0952 ± 0.47 alleles per locus. The markers also exhibited high expected heterozygosity (He) and polymorphism information content (PIC) ranging from 0.6362 (ETH3) to 0.8629 (SPS115) with a mean of 0.7681 ± 0.013 and 0.592(ETH3) to 0.83(CSSM66) with a mean of 0.7256±0.014 respectively, signifying them to be highly informative. Low overall probability of identity (PI) of 0.0943 ± 0.008 and high overall probability of exclusion (PE) of 0.9619±0.02 with the increasing locus combinations were observed. The probability of exclusion was cent per cent (PE=1.0000) when a combination of 8 markers were used with one known parent and a combination of 12 markers when excluding a putative pair, suggesting the efficacy and suitability of the markers used in the study for parentage testing on Jersey crossbreds of Tamil Nadu.
