Milk yield recording and concentrate feed ration calculation for dairy cows
First Claim
1. 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.

Abstract
System for determining supplementary feed rations for dairy cows, which comprises the steps of:
(a) recording in a hand-holdable microprocessor-based recorder (1) information relating to the cow identity of each of a plurality of cows which are to use a milking parlor,
(b) entering information relating to the cow identity of each cow actually entering the parlor 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 (30), 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.

7. Apparatus for determining feed concentrate rations for dairy cows, comprising:
-
a hand-holdable microprocessor based recorder having a keyboard, a solid state memory having a section in which cow identities are pre-recordable and a section in which identities of cows entering a milking parlour for a milking session are recorded, and a comparator unit for comparing entered cow identities with recorded cow identities in order to verify the latter, a master processor unit to which the recorder is connectable to enable the master unit to record milk yields (Y) previously entered into the recorder via its keyboard in relation to the validated cow identities, the master unit having a temporary memory for storing the milk yields and a permanent memory for storing pre-determined values for "maintenance +" (M), lactation period (L(t)) and cow condition (C) in relation to cow identities, and including an arithmetic unit for programmed computation of feed concentrate ration (R) in relation to cow identities generally in accordance with the algorithm;
R=V(Y-M+L(t)+C),means for displaying the computed feed rations in relation to cow identities. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
