Influence of Food on Milk. 



553 



The Ministry of the Interior and the Director-General of 

 Public Health reserve the right of taking every precaution 

 in the case of animals capable of transmitting infection, 

 either by detaining them in quarantine, prohibiting their entry, 

 or oidering their immediate slaughter without the importers 

 being entitled to any compensation. 



The following regulations included in Chapter IV. of the 

 Customs Orders of 1894 also affect the introduction of live stock 

 into Spain. In accordance with the Royal Orders of the Minis- 

 try of the Interior, dated December 31st, 1887, September 6th 

 1888, and January 16th and February 6th, 1889, the introduction 

 into Spain of cattle, sheep, goats, and swine from abroad can be 

 effected at Custom ports of the first class. 



The consignments on arrival will be inspected by a veterinary 

 officer specially appointed for the purpose. Consignments of 

 cattle not completely free from epizootic disease may not be 

 landed, and must be re-exported in forty-eight hours. In case 

 of other disease only such of the cattle as are free from it may 

 be imported for consumption. 



Cattle on being imported must not be slaughtered for public 

 consumption within ten days of their arrival. The disembarka- 

 tion or introduction of cattle will not be allowed unless it be 

 ascertained that the importer has in readiness, and approved by 

 the competent authorities, the requisite accommodation for the 

 cattle during the above-mentioned period. Milch cows which 

 are passed as healthy are exempted from this provisional deten- 

 tion of ten days. 



Many experiments have been made in recent years with a 

 view to test the influence of food on the yield of butter-fat 

 in cows' milk, and the conclusion arrived at ; 

 of 1166 stated in general terms, has been that the 

 Food on Milk, amount of butter-fat a cow gives is not 

 materially dependent upon the nature of 

 her food, but is governed by other causes, such as the period 

 of lactation and the individual characteristics of the cow, 

 together with such influences as inclement weather and under- 

 feeding in winter. At the same time, as was pointed out in
