THE Wairarapa Age MORNING DAILY. THURSDAY, MAY 9, 1912. BY-PRODUCTS OF MILK.

The high price realised for cheese this season on the London market has induced several butter companies to put in a fchral plant for the coming season with a view to substituting cheese for butter when the market warrants dib. This is a< costly proceeding, as tlie ■butter plant Hying .idle soon deteriorates an ilalue, and would thave to be written down heavily every year. Where small farmers are .in close proximity and the whole milk can be conveyed to the factory without travelling a Itang distance, cheese factories can 'be established with .advantage. The example of South, Waivarapa is proof of this, but where farms 'are widely scattered lit does not pay to cart the whole milk on account of the distance to the factory. In the latter case .home separation has to he resorted to (and Ithe -cream- only is carried to the factory, leaving the- freshly skimmed uniiilk on the farm, .as a valuable food Ifor calrves and pigs. The farmers within driving distance o? the factory take their whole milk and -bring back i(in the case of -cheese fectories) whey and from the butter factories the separator imilk. Dairying companies tare beginning to turn ,fheir attention to the (by-product's idf imilk, with a 'view to getting 'better returns. Tn (the -cheese factories ithe whey is being /treated, «ln.d means' taken to isave all Ithe hutter from it that otherwise is. carried off in the whey. This rmay not seem a serious litem, but in a large (factory as much whcy-ibutter has been

saved by tlio introduction of r.ew machinery as would pay the milking expenses of ithe factory. The most 'important byproduct, however, appears .to ibe casein. It is manufactured from the .sweet skim-milk after the ifat has been extracted by the separator. After 'being pressed and dried, (the casein is packed in 100.1b bags and exported to Kuirope, There is a whey Heft after ithe ea«cv;i is extracted from the skim, milk, which, mixed with other fat and solids, makes a valuable feed for calves and pigs. Butter manufacturers anight 'well consider the question cf manufaeturiug casein as ia by-product. From enquiries we have ■made w,c iwidc-rstand the necessary iplant could be instal'lsd for from £2OO fto £3OO, whereas a cheese plant (would .mean an outlay of something dike £IOOO. Only those sending their /whole milk to the factory would, as 4i matter of course, (participate in the profits arkiiing from the gale of casean, and Ithey would have, to bear the cost of the installation of the machinery and the working expenses. It is essential that the hard-working dairy farmer should have every penny that can be made out, of the milk, and the (Directors of the Companies that manliipiulate the milk should talko advantage of every opportunity offered to increase the .returns by utilising .the byproducts. ...•-.
