aTATEMKNT OF It. P. A. MQRIN, VETERINARY SURGEOH AT THK ROIAL DEPOT AT LANGONNET. 



A LAND owBerin the United' StBtcfs; Mr. Wimr, seems to have had the first practice in spByihg 

 cowB. Theobject of the (iteration was to maintain in (he cow, "Without intemiptibt), a sdpply of ', 

 die skme quantity of milk that she g^ve at the time' of spayWlg.-- Ndtwilhstaijding the favorable 

 resalts that Mr. Wiiin claimed to have obtained, the operation r^tai;inedatpiast unknown in Fi'ani^ 

 until a veterinary sargeon of Lausanne (a Swiss), M. Levrat made kijiowh the experiments prac- 

 tised by him,' and tkeir efifedts. The Treatise of M. Levrat etida with the following conclusions : 



- *- The effect of Splaying seems to me to ca.nae a moi-e ftliitiidetnt and constant secretion of milk, 

 which possesses also superior qualities, whence the following advantages result to the proprietoi' ; 

 ^ "1. An increase of oiie third in the quantity of milk; 

 . "S. The certainty of having ftlratAtcOnstaritly the same quantity' pf milk. 



"3. Exemption from accidents which niayha|>pen during the period of heat, when the cows 

 monnteach Other, or are covered by-tool^gebiiUs; - '' ' ■ 



" 4. Exemption from the risk of accidents which sometimes accompany or follow gestation and 

 calving. ..","'-■'--'.■:'•■ ■:'.■" !'"■■;.- - •., - r .■.■•.,.■-;-• 



"5. Ease in fatting e6ws, when their milk begins to dry tip.^' 



" 6. In fine, spayiag isthe only means of preventing onerous expenses, occasioned by cows be- 

 coming 'Umreherei,' "Which is so frequently the ease in some countries, that it is rare to see cows 

 kept more than two Or three years without getting in this state : as for exainplet in the envirtins 

 of Lausanne. and Lavaux, wheref they are bbligeS for this reason to change all fheir cows eveiy two 

 or three years, which is quite ruinous." ■ - ■ 



"M. Levrat confihitedi sfter a year's observations, this fast, that the qiiahtiiy of milk was con; 

 atantly kept the samer sifter the time of spaying. "- 



• M. B^ere, veterinaSy surgeon at Bbrdeanx^ inserted in the ReeiitHe MSdecineVetirinaire, a 

 series of fabte upon the spaylngf of cows,' that had beeir ^led Upon by various piiDpiTetora.- 



It appears fioBa these fiiots, which he recounts with inany details, aad.whbseaathenticify is fixed, 

 that the spayed-cowsliave given without interruption ailep the operation, a quatltity of mUk at 

 leak double fh^ av^age of what they gave duiing the preceding: yeai's. " After the researches 

 tbtit I bavem&de ranee I commenced all these experiments, to the present time," says M. B.£g€re, 

 'fitoB calculation is'veiy exact, and if the cows continue to give milk during their whole life, in 

 like manner, the Operation of spaying will furnish incontestable advantages, particularly in large 

 cities, and theu"vidnity, 'inrhere fpdder is very dear, and where milk always sells well.'' 

 'A remark made l*)r MM; tevret and Hegdre, is that some cows, although they have been spayed, 

 have had their heat, notwithstanding thfe rOtnovaV of their ovarium, and the incapadty for their rg- 

 {ttodnfstion. These animals present, at (he -time of their heat, thisdiftreiice from w>hat we remark 

 during the same period in cows not spayed, that their milk does not undergo any alteration in either 

 quantity or qnali^. 



We may add, that the school of Altbrt has, recently, pfactisbd this operation upon different cows, 

 and that M the results dbtained haVe reached ibie point we have ^bove sttited. 



Leaving thi^ we arrive at the facts detCTminedT^TklVMorin. '. ' 



" Young cows, ought to receive that nourishment^- which -favors the secretion of milk, and which 

 iii coifseqnenoe renders active thei*' lBotifeifett|yeSs&Wi ''rh'e cow is not Usually in full production 

 (mtil after the thit-d or fourth calf; she coutihtfes , to give^'Ute samereturn lip to the seventh or 

 efg-hth ;• from this time lacfeitioh dimini^eS after each new UalVihg, On the other hand; from tlie 

 iflbnient that the cow has received the btill, and gradAalfy as gestatfon advaiicesi the quantity of 

 milk progressively diminishes in nibst 'brebds, lintil three or firar moiiths before Wealthy parturition, 

 the Secretion of milk is almost nothing. It is (o guard against this loss, and other inconveniences, 

 that we lay down vvhat we have obtained after some yisars' experience ih ispaying the cow, and 

 the happy results that we meet with daily.' 



OP THE SPAtlffO OF THE COW AND THE ADVANTAGES, t* TH ft' OPERATION. 



'" The operation of spaying in thecow is productive of great adyaiitaireis. 

 "1. The'cow spayed a short tiine aftercalving, that is to Bay, tbirly or forty days afterwafd, and
