 The images appearing here are the best quality 
 possible considering the condition and legibility 
 of the original copy and in keeping with the 
 filming contract specifications. 
 
 Original copies in printed paper covers are filmed 
 beginning with the front cover and ending on 
 the last page with a printed or illustrated impres- 
 sion, or the back cover when appropriate. All 
 other original copies are filmed beginning on the 
 first page with a printed or illustrated impres-

 or illustrated impression. 
 
 The last recorded frame on each microfiche 
 shall contain the symbol — ♦- (meaning "CON- 
 TINUED"), or the symbol V (meaning "END"), 
 whichever applies. 
 
 Maps, plates, charts, etc.. may be filmed at 
 different reduction ratios. Those too large to be

 beginning in the upper left hand corner, left to 
 right and top to bottom, as many frames as 
 required. The following diagrams illustrate the 
 method:

The Principle of Self-feeding.

 it ri'tVrs to tlie u»u of an automutic di'vioe whicli allows the animal!! ooiiMtaut acuesst

 nu'thods. 
 
 Bequirements of a Oood Self-feeder for Swine. 
 
 Sneh a device to he s\iccessfiil must he cheap, strontr. eapneiou?, iwrtable, onsy to >. 
 eon«tr\ict. weatlier-tifxiil. easy of rcfiidalion for diflerent te.\ture<l na'als. an<l most [ 
 important of all. so arranjied that the contents will feed into the trouj^hs without any j 
 -tcippaffe caused by the blocking of the meal in the hoi>iH'r. Further, the troujrhs nuist 
 be constructed to ensure the minimum amotint of waste such as miffht be caused by } 
 the uniinals iiosinj;: the ineal over the sides or soilinfr it by staiulin^r in the troughs. 
 While several plans of feed<T are reeonmu'iided. the one herein illustrated and described 
 has been found to include nearly all of the desirable features mentioned. 
 
 Advantages of the Self-feeder over Hand-feeding Methods. 
 
 1. .*saves over .'lO imt I'eni of the labour. .. Heduees waste of fe(<d to the mininuim. 
 •">. Prevents di;.'e>tive trciubles due to over-feediufj — the pi(fs having' full acee>s to the 
 na'iil at all times and therefore eatiufr in small iimmtities frei|Uently. instea<l of 
 -uddenly overloailin>f the stumacii two or three tiin(>- in the day. 4. Will iiroduce 
 t'aius eiiual to hund-feedinjr methods at less cost. 
 
 Correct Conditions foy Using the Self-feeder. 
 
 Place the feeder on a iilatform or floor that will remain clean dnriiip wet weathe* 
 and j)ru\e acccssilric \i> the pijjs at all times. Provide .-hade of some sort, either tr' 
 nr a roUfib sheil. While this system of feediu'j will prove relatively economical in 
 lot feedin-r wliere frrcen food, skim-milk or water are supplied daily, the nui.xin. .i 
 etticieney will be reai'hed where the feeders are placed in a nood clover or alfalfa pas 
 tiire. In any case, dry lipt it pa-ture. with or without milk products, fresh water shoulii 
 always be supjilied. preferably r\ninin^. or from some self-watering; device, regularly 
 and frequently tilled. 
 
 When to Use and When to Avoid the Self-feeder. 
 
 Yoimtr i)ips from ten weeks of ape onward may be s.afely and pconomically fo'l 
 by this mcthcKl. Pntil this a;;e is rea<'hed it is ficnerally wisp to feed by hand, althou^rli 
 cxperina'nts have pmved that even suckinfr pigs may be benefited by the feeder. 
 Shoats i>f all asrcs, and in fact all classes of pifrs to be finished (|uickly for marki ' 
 may be most profitably " self -fed." Youni; breedintr stock, similarly, are bcnetite I 
 provideil the ration is one nf a bone- and muscle-forminj; mtture. In pciaTal. avoi 1 
 self-feediuK with a^ed sows, particularly as farrowinp time approaches. 
 
 Heals and Mixtures Adapted to Use in the Self-feeder. 
 
 From a mechanical standpoint prneticnlly any mixture of wholo or proimd frrnii ■ 
 or other mill-fec<ls may be «uccessf\il!y fed. Corn for exampli' is frei)ueritly fed aloi i-

 thus proteetinp the joint. Ilie |ihotofrra|ih shows a feeder with the tillin>r door at one 
 side, the aim heiiiji to do away witli the .joint in the roof. While both are sntisfaetory 
 aM<l similar in the more iin|Mirtaiit details, possibly the first type is to be especially 
 recommended.
