Note in Explanation op Above Table — How to Estimatb Milk and Butter Fat Produced bt a Cow. 



The purpose of the above table is to enable an estimate to be made of the amount of milk and butter fat which a cow will produce in a week. It is 

 intended for the farmer who weighs the milk obtained from each cow, but who has not the time to add up the milk sheet. It is a table that is simple 

 and easy to understand, even though it contains many figures. If it is studied five minutes^ it can be understood easily. 



The first left-hand column shows the amount of milk which a cow may give at a milking. If you have a cow which gives about an average of ten 

 pounds at a milking, look down the first column of figures until the number "ten pounds" is reached. The number just opposite in the second column of 

 figures is the amount of milk which the cow will give in a week. The butter fat the cow pro(luces in one week is shown in the other columns of the table. 

 The numbers at the top of these columns designate the per cent of fat that the cow's milk may test. The numbers in the column below the per cent of 

 fat designate the amount of butter fat the cow will give in a week. The amount of butter fat given by any cow in one week is measured by the figures in 

 the "amount of butter fat" column which are opposite the amount of milk given at a milking — the first column. 



An example: Glance down the column given to Cow No. 1 on the weekly milk sheet, and determine the average amoimt of milk given at a 

 milking. If the average number of poimds of mOk at a milking seems to be 10 pounds, a comparison with the estimate table will indicate that she will 

 give about 140 pounds of milk in a week. Place this down as the total amount of her week's milking. Then glance across the table to the column which 

 shows the per cent of fat which the cow's milk tests, and if it is 4 per cent, the number in the 4 per cent column opposite the 10 pouncJs in the &st_ column 

 will measure the amount of butter fat made during the week — or 5.6 pounds. In a similar way, the amount of butter fat secured can be ascertained for 

 any given amount of milk and for any per cent test shown on the table.
