Subjective Evaluation Of Teat Canal Anatomy, R. D. Appleman

Department of Animal Science: Faculty Publications

Since radiographic techniques have shown that streak canals with larger diameters tend to milk-out faster and are more susceptible to new intramammary infections, a practical visual test was sought to provide easier determination of cows with either extremely narrow (slow milking) or extra wide (susceptible to new infections) streak canals.

A subjective teat classification scheme was developed to describe five different teat-end shapes in 159 Holstein and Brown Swiss cows in the University of Nebraska dairy herd. Approximately one-fourth of the cattle had pointed or round teat ends, one-half had fiat or near flat, and one-fourth were either disk or …

Sheep Meat Production Trial, Department Of Agriculture, Western Australia

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

Better understanding of Middle- East, European and Asian market requirements for Australian sheep has influenced the design of a large meat production trial at Avondale Research Station.

The trial will supply basic information on sheep meat production and involves examples of breed types available in Western Australia and capable of supplying young, lean animals all the year round.

Prime Lamb Production In Western Australia : A Review Of The Development Of The Prime Lamb Industry In Western Australia, R J. Suiter

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

PRIME LAMB production in Western Australia has evolved into an industry based almost entirely on the local market.

This has not always been the case. In the 1930-40 era a substantial proportion of the State's prime lamb production was exported to the United Kingdom.

During this era the industry was equally dependent on exports and local market.

Genetic Aspects Of Calving Ease, James S. Brinks

Department of Animal Science: Faculty Publications

Several trends in cattle production and marketing are becoming evident. Leaner and perhaps heavier muscled slaughter cattle will be in demand through the chain from consumers back through retailers, packers, feeders and finally the producers. Emphasis on growth in the feedlot will continue. Thus, the feedlot and carcass characteristics desired point towards fairly large, heavier muscled cattle. At the producer level, increased emphasis is being placed on matching cow size, milk level, and overall biological type to available resources. Thus, the trend for maternal herds in the Great Plains point towards an adapted, probably moderate size, and milking cow that …

Ultrasonic Testing : An Aid To Better Breeding, B M. Goss

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

THE ultrasonic tester was originally developed as a metal flaw-detector for industrial purposes, and its usefulness for making carcass measurements on the live pig was first demonstrated about 10 years ago.

Effects Of Management, Strain And Truck Shipment On Albumen Quality Of Eggs, J.L. Adams, J.L. Skinner

Department of Animal Science: Faculty Publications

Very little has been reported on changes in quality of eggs during shipment. Gwin (1952) reported a study involving more than a billion eggs purchased by the Armed Forces of the United States. U.S. Grades were determined by candling and inspection by trained inspectors from the Army Veterinary Corps and the U.S. Department of Agriculture. Quality loss was shown to be related to time in transit, distance or miles in transit and seasonal influences. No data were reported as to the relation of varying physical conditions during transit or position effects within the rail cars. Adams and Milam (1960) studied …

Bulletin 118 - Pigs And Pig Raising, P. G. Hampshire

Bulletins 1 - 2999

The importance of the development of pig-raising as one of the primary industries of Western Australia cannot be too greatly stressed.

In Western Australia we have a deficiency in production of bacon and hams equal nearly £200.00 per annum. When this exceedingly profitable market has been satisfied, export markets are geographically very favourable to Western Australia pig raisers as compared to the rest of Australia.
