More Sheep Per Acre, Department Of Agriculture, Western Australia Jan 1966

More Sheep Per Acre, Department Of Agriculture, Western Australia

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

In the late 1950's agricultural scientists in Western Australia became convinced that much of the improved pasture in the agricultural areas of the State was going to waste.

The results of the early trials resulted in many farm demonstrations of higher carrying capacities on improved pastures in southern agricultural areas.

The Avondale Stocking Rate Experiment, L D. White, R. J. Lightfoot, R. N. Glencross

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

THERE is now ample evidence that stocking rates well above the usual district levels can be carried in the Avon Valley.

However, many aspects of increasing stocking rates still require investigation, particularly with lambing ewes and young sheep.


Stocking Rate And Rate Of Superphosphate In A Higher Rainfall Area, P P. Mann, B. J. Gorddard, R. N. Glencross, E. N. Fitzpatrick Jan 1966

Stocking Rate And Rate Of Superphosphate In A Higher Rainfall Area, P P. Mann, B. J. Gorddard, R. N. Glencross, E. N. Fitzpatrick

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

In its virgin state the area carried a forest association of red-gum and jarrah, and the soils are typical of large areas in the south-west of Western Australia.

These gravelly soils have a high requirement for phosphate during their first years under pasture, and this trial was designed to investigate the relationship between rate of phosphate, stocking rate and pasture production over a number of seasons.


Values Of Commonly-Used Protein Supplements In Broiler Rations, D F. Hessels Jan 1966

Values Of Commonly-Used Protein Supplements In Broiler Rations, D F. Hessels

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

THE performances of broiler flocks in the latter part of 1964 were below standard. Low body weights and a high incidence of gizzard erosion were common on farms.

It was therefore decided to test the biological valuss of the commonly-used protein supplements and also to try to find a correlation between gizzard erosion and any of the protein supplements.


Enterotoxaemia (Pulpy Kidney Disease), J Craig Jan 1966

Enterotoxaemia (Pulpy Kidney Disease), J Craig

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

ENTEROTOXAEMIA, or pulpy kidney disease, is found in all areas of the world where sheep are raised and has occurred in Western Australia for many years, particularly in the great southern districts.

At one time it was known as "Beverley sheep disease."

The infectious nature of enterotoxaemia was first described by Bennets in 1932.

The June-July period is excessively wet, causing extensive waterlogging of the soils.


1966 Beef Cattle Progress Report Of Research Activities, E. F. Frolik, H. H. Kramer Jan 1966

1966 Beef Cattle Progress Report Of Research Activities, E. F. Frolik, H. H. Kramer

Nebraska Beef Cattle Reports

Many beef cattle breeders in the United States and other countries are following the progress of the selection experiment at the Fort Robinson Beef Cattle Research Station, Crawford, Nebraska. Three lines of Hereford cattle from the same genetic foundation are under selection. Line 21 is selected for 200-day weight. Line 22 is selected for yearling weight. Line 23 is selected for an index combining yearling weight and a score for muscling and fat thickness.

Each line is operated as a closed herd so it will be possible to determine how much improvement in economic traits can be made by selecting …

The Gross And Microscopic Anatomy Of The Ducts Connecting The Testis And Epididymis In The Mouse, Bruce F. Lindgren Jan 1966

The Gross And Microscopic Anatomy Of The Ducts Connecting The Testis And Epididymis In The Mouse, Bruce F. Lindgren

All Graduate Theses, Dissertations, and Other Capstone Projects

In man and other mammals including the mouse, spermatozoa are produced in the testis. Before they are mature, spermatozoa leave the testis and pass through a system of excurrent ducts where they acquire an enhanced capacity for fertilization (Young, 1931; Blandau and Rumery, 1961). These ducts include the tubuli recti, rete testis, ductuli efferentes, ductus epididymidis, and ductus deferens. The contribution of individual parts of this excurrent duct system to spermatozoan maturation is poorly understood.

This study was undertaken to describe the gross and microscopic anatomy of the tubuli recti, rete testis, ductuli efferentes, and their proximal and distal connections …

A Potential Champ? [Distemper In Dogs], F C. Wilkinson

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

THE mother of this pup was an eight-year-old sheep dog and in the eyes of her owner she was a champion and well worth her keep.

She was perhaps slowing down a little, so the best looking pup out of the last litter had been kept as a possible replacement.


Relationships Among Some Physical And Chemical Parameters Of Full- Versus Limited-Fed Yorkshire Pigs Slaughtered At Different Live Weights, G. M. Babatunde, W. G. Pond, L. Dale Van Vleck, G. H. Kroening, J. T. Reid, J. R. Stouffer, G. H. Wellington Jan 1966

Relationships Among Some Physical And Chemical Parameters Of Full- Versus Limited-Fed Yorkshire Pigs Slaughtered At Different Live Weights, G. M. Babatunde, W. G. Pond, L. Dale Van Vleck, G. H. Kroening, J. T. Reid, J. R. Stouffer, G. H. Wellington

Department of Animal Science: Faculty Publications

An experiment was designed using 30 Yorkshire pigs to study the influence of slaughter weight and feed restriction on carcass cut-out data and to relate these physical measurements to the chemically-determined proximate components. As slaughter weight increased from 79 to 102 kg., the percent of all lean cuts decreased significantly, while that of fat cuts and back-fat thickness increased significantly. Absolute amounts of both fat and lean cuts increased with slaughter weight. Feed restriction significantly increased most of the lean parameters studied and reduced the fat measurements. It increased percent of head and reduced the percent of offal (gastrointestinal tract …

The Effect Of Methods Of Storage On The Gross Energy, Chemical Composition And Feeding Value Of Alfalfa, Guru Prasad Mohanty Jan 1966

The Effect Of Methods Of Storage On The Gross Energy, Chemical Composition And Feeding Value Of Alfalfa, Guru Prasad Mohanty

Electronic Theses and Dissertations

Production of good quality hay or silage and its proper storage without loss of the nutritive value is an important problem for dairy farmers. They are particularly interested in meeting the energy needs in feeding their herds for milk production. During the past decade there has been a substantial increase in the volume and intensity of research towards the nutritional and calorimetric aspects of cattle feeds. A number of unavoidable problems come in the way of their application causing financial disaster in today’s competitive economy of dairy farming. To increase milk production or to maintain a high level of production, …


Trichinosis, Usda Jan 1966

Trichinosis, Usda

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Trichinosis is a disease that is caused by small threadlike worms called trichinae. I It is not catching. People get trichinosis when they eat raw or underdone pork that contains trichinae. Few of the millions of hogs killed each year for food have living trichinae in their muscles, but, since there are some, you should never eat pork that is not properly cooked. Cooking pork throughout kills the worms.


Some Helminths Of Itasca Park Fishes, Omer R. Larson Jan 1966

Some Helminths Of Itasca Park Fishes, Omer R. Larson

Journal of the Minnesota Academy of Science

A helminth survey was conducted'. on 12 species of fish taken from the waters of Itasca State Park. An abundant and varied helminth fauna was found, with 3 l parasitic forms identified to genus or species. By taxonomic groups these included, 20 trematodes, 5 cestodes, 2 acanthocephalans, and 4 nematodes. Every fish examined was parasitized, but yellow perch and rockbass possessed the greatest variety of helminths. Based on the results of this survey, several aspects of parasite life cycles, geographic distribution, and hast specificity are discussed.


Stocking Rates With Growing Cattle At Wokalup Research Station, Maurice C. Cullity Jan 1966

Stocking Rates With Growing Cattle At Wokalup Research Station, Maurice C. Cullity

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

CONSIDERABLE attention has been given in Australia and in overseas countries to methods of grazing control, and to the effects of varying stocking concentrations.

There is evidence that the highest yields per animal—of milk or butterfat per cow, or of weight increase per growing or fattening beast—are not necessarily a true reflection of the greatest output from the farm, as indicated by the measure of yield per acre.


A Sick Ewe Why? [Pregnancy Toxaemia], F C. Wilkinson Jan 1966

A Sick Ewe Why? [Pregnancy Toxaemia], F C. Wilkinson

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

THIS dazed-looking ewe was seen wandering aimlessly around with an unsteady gait.

Three other ewes had died after a similar sickness lasting about four days.

Two more sheep in the flock of 350 ewes were also sick. One of them was down with its head on one side.

Skim Milk : Is A Valuable Pig Feed, But It Should Be Balanced By Other Foods, P Mcnamara, R. Sprivulis Jan 1966

Skim Milk : Is A Valuable Pig Feed, But It Should Be Balanced By Other Foods, P Mcnamara, R. Sprivulis

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

SKIM milk is a source of high quality protein, and as such is a valuable feed for young pigs.

Pigs will live and grow on skim milk alone, but it is not a balanced food. You will not get the best out of the milk or the pigs if the diet is not balanced by other foods.
