Dairying is no longer a simple farmer-customer business. It has become a highly organized and diverse industry: One major achievement in Ontario has been a study tein- vestigate the composition of milk. The basic components of milk are termed generally as total solids. This category can . he broken down into two groups, the first of which is fats. The second group is called solids- not-fat and includes protein, lactose, and minerals, .New laboratory methods such as the use of the Infra Red Milk Analyzer (IRMA) in . de- termining the components of milk, now make it possible to test regularly and accurately for all components, not just butter- fat. vide each plant with semi- monthly information on the average compOsition of milk it is receiving. This is a v ery significant breakthrough and at the present time there is no other country in the world that can provide this information.. In this way dairy producers can watch changing trends in milk composition. stock, As a result, much research iated arid condu.cted by the Dairy Branch of the Ontario Department 4 400 Cows The study had three broad 'obj ectives. Researchers sought to determine the effects of fact- ors such as age of the cow, stage of lactation, season .of the year, breed, incidence of mastitis, and line of breeding; on the protein, lactose, fat, and solids- not-fat on milk from individual cows. The second objective was to determine also the accuracy and practicability of newly pro- posed tests'for protein and solids- not-fat. The final proposal was to and the average composition of milk produced in Ontario taken from samples from milk plants throughout the prOvince. Basic information had to be obtained before the dairy indus- try •could consider recommend- -ations relative to marketing and breeding programs involving milk constituents other than butterfat. Forty herds, ten of each of the four main dairy breeds in Canada - Ayrshire, Guernsey, Holstein-Friesian, and Jersey - were selected, making a total• of approximately 1,400 cows. It was revealed that the four dairy breeds that were used will rank in the same order for all milk components expressed as percentages, except lactose, which shows little variation from one breed to another. Lactation curves fur protein, total solids, and solids-not-fae,L. percentages have the same gen- eral shape as the curve for but- ' • terfat with the low point falling NEWS OF CONSTANCE SEAFORTH MONUMENT- ORKS All Types of CEMETERY MEMORIALS OPEN DAILY T.

This is one of the main reas- ons that the milk study Was of Agriculture and Food, ' the Departments of Dairy Science and Animal Science of the Ontario Agricultural College, • the Department of Veterinary Bacteriology of the-Ontario Vet- erinary College, and the Pro- duction and.Marketing Branch of the Canada Department of Agriculture. Dietary trends were chang- ing and many people decreased their consumption of fat. Sales of high-fat dairy products de- creased relative to sales of low- fat dairy products. PrOtein's high nutritional value became .the subject of much advertising. 'Therefore, because of the nqed for high quality protein through- out the world, it seemed feas- ible to investigate die vario.us components, particularly pro- tein. In this way, the environ- mental and genetic factors af- fecting these components could be determined. • From such 'a study, research- ers concluded that it would be possible for dairy cattle produc- ers fo develop breeding and se- • lection programs aimed'at changing the composition of milk to meet current demands. It has been suggeSted that•less emphasis should be placed on butterfLat, a major criterion for •selection for Mier half a century.

For central laboratory test- ing of whole milk for butterfat, protein, lactose, solids-not-fat and total solids, 'IRMA proved most accurate and effiLient. IRMA has since become an offic- ial test for milk fat for payment, purposes in Ontario. Although IRMA works equally well, the Babcock method of butterfat estimation in field test- ing still remains a' satisfactory procedure. i It was found that for an in- crease of one unit of the Califor- nia Mastitis Test value, the fol- lowing average changes occurred : lactose concentration in the, rriilk decreased 0.100%, solids-not-fat decreased 0. 046%, protein in- creased 0, 042% and monthly milk production decreased 49 pounds per cow. These changes were independent of the effects of age of cow, stage of lactation, and - month of year. Based on the distribution of California Mastitis Test reactors inthe herds in this study, and using a 40-cow herd with the same kind of distribution, a loss of 1,470 pounds of milk per month could be expected com- pared with a"herd without react- ors, Correspondent MISS MARY Mc1LWAIN Mr. and Mrs. Jack Nledd, Mr. and Mrs. Clifford Adams of 1_,Onesboro spent a few days at Hope Bay, Billy and Debbie Preszcator spent the week end with Mr. .and Mrs. Bill Dowson, Brenda, Bonnie and John 'of Varna.

The medium relativity be- tween protein and butterfat per- centages indicates that by sel- ection for butterfat percentage, dairymen haVe been in the past selecting to the minimum degree for protein. This relationship is! not sufficiently high, however, 'to say that all high-fat milk will also have, high protein. If protein were, to become the de- sired component in milk, it , • would be advisable to test, and select directly for it rather than indirectly. through butterfat. A relatively low relationship between protein' and lactose in- "dicates that• it is inadvisable to test for solids-not-fgt .as a rou- tine procedure for evaluating cows. Finally, the fairly smooth shape of the lactation curves and the magnitude of the re- peatability values based' on monthly tests within the same lactation clearly indicates that monthly testing will give re- liable estimates of lactation totals, when considering any of the milk constituents.
