Analysis of cow health, fertility and production

This command analyses the performance of cows present in the herd during a specified period. It operates in a similar way to the Cow performance summaries form except this command includes cows present during the analysis period, irrespective of whether they have subsequently left the herd. 

The command gives an overview of a range of parameters for cows in the period specified. You can choose from a range of summaries (Data to include in report) and see how these vary against a selected variable (Variable to use for column heading). Reports appear as cross-tabulations which can be saved for future use (Summary format):

- the analysis period for defining the cows you are studying. Any cow calving in the period specified will be included from that date until either she left the herd or the end of the analysis period.

Variable to use for column headings: The values displayed in the column headings of the grid are determined by the item selected in the dropdown box above the grid. In the example above, parity (lactation) is selected so the column headings (1,2,3 etc) relate to the parity numbers of cows currently in the herd. The distribution of the 172 cows between the parities is displayed.

Data to include in the report: The user can select any combination of the summaries offered by selecting the appropriate check box. In the example below the summary of mastitis and lameness are displayed. Note the grid contains an overall summary and summaries for each column item (parity in this example). Changing the column heading to Group would redisplay the grid, summarising the mastitis and lameness for each group.

Identifying the animals behind the figures in the grid: It is always possible to identify which animals are involved in a figure in the grid by clicking the number with the right mouse button.

 In addition to identifying the animals included, the range of values can be displayed by selecting the bar-chart option:
