Heifer’s productions costs are remarkable part of whole milk production costs and that’s why it is important take look at those costs. Usually farmers doesn’t notice heifer breeding totally costs and they thought that costs are lower than what cost really are. As a help in calculating the real costs of heifer breeding Marita Jääskeläinen drew up in the year 2013 via the KeNa project an eHieho- heifer cost production calculator application. So applications work way that how those have plan, usually applications need instructions. So it considered that also in eHieho-application need instructions.

This thesis target is create eHieho-production costs calculator instruction, which help farmers calculate easily, reliable and user-friendly heifer production costs they own cattle. To instructions draw up has used nonfictions about instruction writing and production costs calculation.

This is functional thesis, which report includes short parts about productions costs calculation, heifer viability breeding, instructions creating and Internet publishing because all of those join this thesis main output. The report also describes all the eHieho-instructions as well as the whole process of the thesis from beginning to completion. In the description of the process is told amongst other things how the transfer of the instructions to the website happened, how the instructions were visualized and how with the help of HTLM-language a picture map was created as a main view to help in the use of the instructions.

To results from this thesis came eHieho-instructions, which are available for everyone in Savonia University of applied sciences Hiehohotelli- project web-pages in address: https://hiehohotelli.savonia.fi/index.php/ehieho
