To compute the number of ])ounds 

 weight of butter contained in milk. 



Divide the pounds and decimals of a 

 pound, of milk agreeing with the lest 

 result, into the total number of pounds of 

 milk. 



Example— 1,UU0 lbs. of milJ; tests l.U 

 per cent, butter fat. 



It will be seen above that it 

 takes 22.52 lbs. of milk testing 4.0 to 

 make one pound of butter.

THE UTILITY OF TESTING COWS. 



The accompanyii-io- table of the actual 

 return of a small dairy herd of Victorian 



cows luis been complied with a view of 

 impressing on dairymen the great ad- 

 vantage to be derived from recording the 

 results from each and every cow. 



It is all very well to judge a cow by 

 a})})earances, but practical men are well 

 aware that numy a fine-looking cow is 

 unprotitable for the dairy. At the pre- 

 sent time it is fully recognised that there 

 is no way so reliable to tell a good cow 

 from a bad one as a scales and Babcock 

 tester. The average Victorian cow has 

 the reputation of giving a very small re- 

 turn as compared with the cows of many 

 other countries. Whether this is so oxi 

 not is open to question, and would be a 

 difficult query to settle definitely. 



From previous records it would appear 

 that Victoria possesses some cows almost 

 as good as are to be found in any part of 

 the world. No doubt the greater number 

 are anything but profitable for dairying. 



If bad cows were known for certain 

 and weeded out, and the remaining cows 

 received better attention, our prospects 

 would be bright indeed in the dairying 

 line. 



Uescrii'Tion of Heep. 



The herd of cows under review is a 

 cioss-bred one. There is more shorthorn 

 blood in them than anything else. Aljout 

 three-quarters shorthorn and the rest a 

 mixture, but no Channel Island blood 

 whatever. 



Method of Treatment. 



They did not receive any special at- 

 tention. Each cow was treated alike, and 

 Ihey were all pastured together. With 

 Ihe exception of a limited sup})ly of 

 potatoes for a few weeks, the cows had 

 nothing but straw in addition to pasture. 

 In common with the herd-; in many parts 

 of the Colony last season, this one was 

 reduced to skin and bone for some 

 months. 



As a consequence the cows did not, at 

 their best, give more than throe-fourths 

 of the yield of a normal sea-^on. They 

 were kept in the Koroit district, and the 

 dairy formed an auxiliary to other 

 branches of fanning. 



Cows going out of milk at the beginn- 

 ing of the year and disposed of are not
