ANIMAL PRODUCTION. 



sisted of a basal ration of clover, hay, oats, strav . bran and corn ami cob u 

 nutritive ratio being I : L2.2. In the second period, wel augar heel pulp was intro- 

 duced into the ration, the basal ration being so changed that the drj raatti 

 total ration and the nutritive ratio remained constant. In the third period, the 

 basal ration remained the same as before while the amount of sugar beel pulp 

 increased, the cows receiving all thej would consume. In the second serii 

 the conditions were the same excepl thai in the fourth period dry sugar beel pulp 

 was used in place of wel pulp, the dry matter and nutritive ratio of the ration i i 

 kepi the same as in periods I and 2. 



The coefficients of digestibility were in general lowesl when the analytical data 

 based on the fresh feces were taken into account, and highesl when tin- correi i 



for metabolic products were introduced, bul in ase were constanl differences 



observed which could be attributed to the rations fed. The loss of nitrogen when 

 the feces were dried ranged from .3 to 9. 5 per cent and the amount of metabolic n 

 gen of feces from 8.6 to 15.4 per cent, the variations being apparentl) caused bj indi- 

 vidual peculiarity or other conditions nol determined. As regards the balance of 

 income and outgo of nitrogen, the results varied from a loss of I. I grains per day 

 withoneof the cows fed a basal ration in the firal scries..]' tests to a gain of 12.1 

 grams per day with one of the cows Eed the sugar beel pulp ad libitum. 



•• It is very noticeable thai foods arc utilized differently bj differenl individuals. 

 Two cows, altln.ii._r], D0 th arc healthy and normal in every respect, will nol utilize 

 the same amount of nutrients in a given feed. 



•• In the firsl experimenl both cows showed a slighl increase in digestibility \\ lien 

 l.eet pulp wel was added to the ration. In the second experimenl one cow gave a 

 slight increase, while the other showed practically no change. These figures are, 

 however, so Blighl when an average is taken that they can not be -aid to prove an 

 increase of digestibility due to the succulent feed. 



" In all of the experiments a consideration of digestibility based on the nitrogen as 

 found in the U'i'v> before drying, shows that former figures of digestibility of succu- 

 lenl feeds arc given a1 leasl 5 per cenl to,, high. Differenl \c>-<\- Bho\* varying per- 

 centages of volatile nitrogen in the feces, and inasmuch as it appears with the undi- 

 gested f 1 it >hould l.e taken into consideration, else our coefficients of digestibility 



are considerably too high. . . . 



" Whatever the effect of succulence on the apparent digestibility of a f 1. which 



in these instances seems to be practically nil, it seems quite positive that a succulenl 



f 1 i- digested at less expense t han a dry food. In this way a succulent food should 



work antagonistic to a food rich in fiber and in tin same capacity as -rain. If an 

 increase of cell oxidation is accompanied by an increase of metabolic nitrogen in the 

 \m-< . . . then Burely the expenditure of energy on a f I high in factors ol succu- 

 lence is less than on a dry food. The above being true, it follows that the m t avail- 

 able energy, other factors being equal, is greater in a succulent f 1 than in a dry 



one." 



The utilization of beet leaves, I >. Mk-.ii; {Fuhling's Landw. Ztg., 

 No8. 3, pp. 91 95; ',, />/>. 145-152). The superior value of ensiled and dried beel 

 leaves as compared with the green material is pointed out. According to the author, 

 the dried leaves are generally considered the m08t satisfactory, though he I elieves 

 that ensiling should receive more attention. Experimental data which have to do 

 with the subjecl are summarized and discussed.
