Tests For The Determination Of Milk Quality, H Maslin

Journal of the Department of Agriculture, Western Australia, Series 4

Foolproof tests devised to determine the quality of milk delivered to the factories can detect sub-standard milk with accuracy.

They have an important place in helping achieve a high standard of quality in our dairy products.

Stilling Coastal Sand Drifts With Marram Grass, J L. Mcmullan

Journal of the Department of Agriculture, Western Australia, Series 4

DRIFTS in dunes on the coast between Albany and Geraldton may be stabilised by planting marram grass (Ammophila arenaria).

However, it should be anticipated that much of the planted grass will die before an area is finally stabilised.

Chronic Respiratory Disease Of Poultry In Western Australia, M R. Gardiner, R. V. Vagg

Journal of the Department of Agriculture, Western Australia, Series 4

Widespread chronic respiratory disease was revealed in a survey of respiratory infections in Perth metropolitan area poultry flocks.

Most occur in early or midsummer and cause a serious fall in egg production. Return to full lay after the infection is usually slow.

While these infections can cause production losses in flocks which are under heavy stress, none of the more serious forms of chronic respiratory disease was found.

This gives encouragement for future control of the disease in Western Australia.

Chick Management, D F. Hessels

Journal of the Department of Agriculture, Western Australia, Series 4

A UGUST is the month when most poultry farmers get their chickens. Special attention will be needed in the coming weeks, with nutrition and disease prevention the main considerations.

Lambs Need Drenching At Weaning, Department Of Agriculture, Western Australia

Stress Factors In Pig Raising, P C. Beck

Journal of the Department of Agriculture, Western Australia, Series 4

THE pig raiser who wishes to attain the best possible growth performance from his pigs must recognise factors other than the basic ones of good nutrition and bredin capacity.

These are "stress factors"—minor factors of husbandry which can greatly damage health and limit the growth rate.

A Modified Copper Hot Water System, F J. Fielder

Journal of the Department of Agriculture, Western Australia, Series 4

A good supply of hot and boiling water for cleansing and sterilising utensils is essential for hygienic milk production.

Dairy Instructor F. Fielder, M.D.D., describes an efficient and economical modification of a copper hot water system for this purpose.

SINGLE copper units of 14 or 16 gallon capacity to supply hot and boiling water for the dairy are no longer good enough for most dairy farms.

Mulesing And Tailstripping : For The Prevention Of Fly-Strike, W L. Mcgarry

Journal of the Department of Agriculture, Western Australia, Series 4

MULESING and tailstripping are basic to fly strike control.

During emergencies and bad fly waves they may need to be supplemented by temporary protective measures such as jetting and crutching.

Mycotic Dermatitis (Lumpy Wool) And Fleece Rot Of Sheep, J Shilkin

Journal of the Department of Agriculture, Western Australia, Series 4

Matted and sometimes discoloured specimens of wool are often received at the Department of Agriculture during seasons of heavy rainfall.

Two similar but quite distinct diseases are recognised as having caused this condition.

They are mycotic dermatitis (lumpy wool) and fleece rot. Both conditions damage the fleece and render affected sheep susceptible to blowfly strike.

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.

Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.

Bulletin of the University of Nebraska State Museum (1924–2023)

Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.

Malic Dehydrogenase Activity At 101 C Under Hydrostatic Pressure, Richard Y. Morita, Roger D. Haight

Papers in Microbiology

MORITA, RICHARD Y. (University of Nebraska, Lincoln) AND ROGER D. HAIGHT. Malic dehydrogenase activitv at 101 C under hydrostatic pressure. J. Bacteriol. 83:1341-1346. 1962.-No malic dehydrogenase activity was found to occur at 101 C at various hydrostatic pressures from 1 to 700 atm. However, activity was demonstrated with hydrostatic pressures above 700 atm, with optimal activity at 1,300 atm at the same temperature. Explanation of the data is based upon thermal denaturation of the enzyme, which involves a molecular volume increase of the enzyme. The molecular volume increase is counteracted by hydrostatic pressure. Pressures above 700 atm to 1,500 atm …

Detergents For The Dairy Farm, H Maslin

Journal of the Department of Agriculture, Western Australia, Series 4

CLEANLINESS in both the physical and bacteriological sense is essential to the production of high quality dairy products, and high quality in these products is essential to both the health of the community and the successful and economic operation of the industry.

Detergents have an important place in maintaining dairy hygiene—but they must be properly used if they are to be really effective.

In this article Dairy Instructor H. Maslin, M.D.D., describes the qualities of a good dairy detergent and explains how it should be fitted into the regular cleaning routine.

Ovine Vibriosis : A New Cause Of Sheep Infertility, M R. Gardiner, M. E. Nairn, I. J. Miller

Journal of the Department of Agriculture, Western Australia, Series 4

Vibrionic abortion of sheep has caused heavy losses in a number of wheatbelt flocks. In several flocks up to 50 per cent, of the ewes aborted as a result of this newly reported disease.

This article gives the history of the disease in this State, and describes the symptoms for the benefit of other farmers whose flocks may be affected. Ewes become immune after the first attack.

Nebraska Beef Cattle Reports

Feeding pastured calves protein supplements weekly instead of daily during the winter made little difference in either winter or summer gains, according to research results to date.

Two sources of protein were used in the trial. (I) Second cutting alfalfa hay was fed at the rate of four pounds per head daily. One group of calves was fed four pounds per head daily and one group was fed 28 pounds per head once each week. (2) Forty percent protein, pellets or cake, was fed at the rate of one pound per head daily. One group was fed one pound per …
