US4493290A — Milk yield recording and concentrate feed ration …

Claim 1

Independent Claim 178 words

A method of determining feed concentrate rations for dairy cows, comprising the steps of: (a) recording in a hand-holdable microprocessor-based recorder information relating to the cow identity of each of a plurality of cows which are to use a milking parlour, (b) entering information relating to the cow identity of each cow actually entering the parlour for a milking session, the recorder being programmed to validate the entered cow identities with the recorded cow identities, (c) entering respective milk yields in relation to respective validated cow identity entries, (d) after a milking session, connecting the recorder to a master unit, and (e) causing the master unit to read the information in the recorder as to milk yield Y for each identified cow and enter this information into a central processor programmed to compute a value of feed concentrate ration (R) for each cow according to an algorithm having the general form: R=V(Y-M+L(t)+C), where M, L(t) and C are values for "maintenance +", lactation period and cow condition pre-recorded for each cow in a memory of the master unit.

Claim 2

Independent Claim 178 words
