| Abstract | The present investigation was undertaken to find the efficiency of three data mining techniques to study the sex ratio distortion in crossbred dairy cattle. Information on the date of birth, sex of calf, sire and dam identification number, parity number of dam and date of conception of dam of 873 crossbred calves born to 89 bulls at Cattle Breeding Farm, Thumburmuzhi, Kerala for the period from 1991 to 2005 were utilized for the present study. The three classificatory techniques viz., logistic regression, decision tree and artificial neural networks were employed using the Weka (Witten and Frank, 2005) software. Confusion matrix was developed by each classifier and evaluation of the technique was done by using parameters viz. kappa statistic, mean absolute error, root mean squared error, relative absolute error and root relative squared error. The results revealed that classification by logistic regression was the best as it had maximum (58.72) percentage of correctly classified instances; while the Decision tree (52.75) and artificial neural network (52.29) classifiers had almost similar efficiency. Based on the results obtained in the present study it may be concluded that the sex of calf can be classified using various attributes at an accuracy of 58.70 per cent. The decision tree understands and classifies the problem at a faster rate than the logistic regression and artificial neural network techniques. However, the logistic regression classifies the sex of the calf at a more accurate and better way than the other two classification techniques. Hence among the three techniques used the logistic regression was recommended for the classification of sex of calf in dairy cattle. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
