Not illustrated. 1898 Excerpt: ...a change in the rations caused the per cent of fat increase in Period II., decrease in Period III., and increase in Period 7. Thevariations in the fat yield seldom exceeded one-half of one per int per cow per day, but, when it is remembered that thisis the average r 14 days, the gain or loss in fat incurred by the changed rations has 1 important bearing on the yields and profits derived. This influence more clearly shown when the Groups and the whole herd are consided. (See Charts A, B and C.) Chart A sho'ws the total yields of milk to decrease with the whole herd iring Periods III. and IV., and that the variations between the total Lily yields, and the morning.s and night.s milk, from day to day, were so least in Periods III. and IV. This does not necessarily mean that, e total yields of milk were least in these Periods. In Chart B, where the Groups are considered, we find the milk ineasing through Period I., and starting to increase in Period II. (deease due to temperature), while the highest average milk yield per roup was shown in Period. III., decreasing but slightly during Period 7. In Chart C, the butter yields by Groups will be found.-The butter ineased to Period II., and maintained a high average through Periods II., 1I., and IV., decreasing slightly in Period IV. The sudden fall in temzrature in these Periods did not affect the butter yields materially. From a review ofthese charts, it is plain that every change in the raJns influenced the yields of milk and butter, and the differences disayed in effectiveness show how carefully the relative value of rations ust be studied, or else large losses will be the result. The changed rations exerted a greater influence on the milk yields an on the butter fat in the experiments. Further, a slight decrease t...
