Background: This investigation provides the data of breeding management practices followed by the livestock owners of milkshed and non-milkshed areas and analyze the effect of operation flood program in milkshed area of Bikaner district of Rajasthan in respect to dairy cattle breeding management practices.
Methods: In order to achieve the objectives of this study a field survey was conducted. The information required to complete the study were collected from milkshed and non-milkshed villages of Bikaner district. The data was collected by using the pretested interview schedule by visit to their farm to take visual observations and actual measurements of the various desired aspects. The collected data was tabulated and subjected to various statistical methods to draw meaningful inferences. 
Result: Impact of operation flood programme could most appreciably be seen on the improvement of breeds and breeding methods. Significantly (P≤ 0.01) higher percentage of Rathi and crossbreds (41.89% and 13.14%) were found in milkshed area with the low incidence of natural service in comparison to non-milkshed area having low percentage of pure and crossbred cattle with high incidence of natural service. A significantly higher percentage (54.11%) of dairy cattle owners in milkshed area get their cattle inseminated/crossed after 7-12 hours of detection of heat, whereas in non-milkshed area only 32.22% get their cattle inseminated/crossed after 7-12 hours of heat detection. The operation flood program had statistically significant (P≤ 0.05) effect on milkshed area with respect to genetic improvement of their stock.
