Show PECTIN APPLE-PECTIN AS COW FEED Pulp Should Prove Valuable Adjunct to Fare of Animal When Compared Compared Compared Com Com- pared With Silage Pr PrepAred pared by the United States Department of ot Agriculture That dried pectin apple-pectin pulp should prove e a valuable adjunct to the fare tare of f the dairy cow Is the conclusion drawn from anal analyses ses and feeding trials conducted by the bureau of ot chemistry United States Department of Agriculture AgrIculture Agriculture ture In collaboration with the Bureau of ot Animal Industry This feed made maden madea n a favorable showing when compared with dried beet pulp and corn silage pectin Apple-pectin pulp Is the product by-product remaining after pectin has been extracted ex ex- e. e extracted from apple or or as It ItIs Itis itIs is Is sometimes called press cider cake After the pectin has been extracted bout about three-fourths three of ot the total weight of the he pulp Is water rendering It subject subject subject sub sub- to rapid spoilage Heretofore It has been thrown away but It has been found that when the pulp Is dried it can be kept for a considerable time and nd because of ot Its reduced weight handled and shipped economically Some manufacturers have recently Installed Installed In In- stalled evaporators for dr drying the pulp In order to market the product for for stock feed The feeding experiment Included a preliminary test with one cow for a period of 20 days and a later one with 6 0 cows The dried pectin pulp was always mixed with three times Its wel weight ht of water several hours before feeding In the first test the cow was fed corn silage for 20 days then after atter attern n a transition period of ot 5 days she was given glyen pectin pulp for 20 da days s and after another transition period of 5 days ays she was fed corn silage for anether another another an an- other ether 20 days In all these periods grain was fed In connection with the roughage The average production during the silage corn-silage periods feeding-periods was pounds of ot milk and 1465 1405 pounds of ot butterfat During the period when r Y Yx x A Convenient Arrangement for FeedIng FeedIng Feed Feed- Ing Cows Which Saves Much Labor pectin pulp was fed the cow made SoGO pounds of milk and 1569 1503 pounds of ot fat tat Although this test showed that the pulp produced per cent I more milk and 71 per cent more butterfat butterfat but but- than the corn silage the results results results re re- can not be considered conclusive In the second and more extended experiment experiment ex the pectin pulp was compared compared com com- pared with dried beet pulp a feed that it resembles more closely than corn silage The rhe 0 6 cows were fed for tor 30 80 days s 's on beet pulp soaked with three times its weight of ot water then after a n transition period of ot 10 days they they were fed for 30 days da s on pectin pulp soaked with a similar quantity of water The soaking was from one feeding time to the next but in warm weather the pulp should not be allowed to soak for more than one or two hours The pectin pulp contained approximately 7 per pcr cent crude fat not all aU of which is true fat 7 per percent percent percent cent crude protein and 20 26 l per r cent crude fiber as compared with 05 per percent percent percent cent crude fat 8 per cent crude protein protein protein pro pro- tein and 20 per cent crude fiber in beet beet pulp The two feeds are ure similar in being able to absorb water r readily The cows while on the thc ration containing con conS tailing the beet pulp produced pounds of milk and pounds of butterfat while on the pectin pulp pectin pulp ration ration ra rag ra- ra tion they they produced 7 pounds oi of milk and a pounds of fat Forty pounds of the a wet et pulp were offered to each ach cow dully dally The palatability of the pectin pulp did 1 not appear to be beso beso beso I so high as that of ot the beet pulp since the cows did not eat It so readily It seems that pound for pound of dry matter the pectin pulp pulps I.
