The Effect Of Frozen Storage On The Microflora Of Raw Milk, Jaswant Singh

Electronic Theses and Dissertations

The proper handling of milk samples prior to bacterial analysis has been somewhat of a problem to dairy processors of South Dakota. There have been, and still are, many queries by these people about the treatment of o milk sample prior to the determination of a bacterial count. Should the milk samples be frozen prior to determining the number of bacteria? If it is feasible, what effect will the freezing have on the number of bacteria found? No tangible information about this problem has been found in the literature. Standard procedure emphasize mainly the icing of milk sample before analyzing …

Comparative Study Of Milk Quality Tests On Manufacturing Grade Raw Milk, Donald L. Wallace

Electronic Theses and Dissertations

One criterion used to determine the quality of milk is based upon its bacterial content. This immediately emphasizes the problems of determining milk quality. Bacteriological tests are, at best, only estimates of the number or the activity of the organisms present. Since its introduction to South Dakota dairy farms, the bulk tank has continued to increase in popularity. Its increased acceptance has caused new problems in determining milk quality. The bulk tank allows the farmer to cool the milk faster and more efficiently than ever before, thereby limiting bacterial growth. Quality tests should not only differentiate between good and poor …

Predator And Rodent Control In The United States, A. S. Leopold, S. A. Cain, C. M. Cottam, I. N. Gabrielson, T. L. Kimball

United States Fish and Wildlife Service: Publications

In a frontier community, animal life is cheap and held in low esteem. Thus it was that a frontiersman would shoot a bison for its tongue or an eagle for amusement. In America we inherited a particularly prejudiced and unsympathetic view of animals that may at times be dangerous or troublesome. From the days of the mountain men through the period of conquest and settlement of the West, incessant war was waged against the wolf, grizzly, cougar, and the lowly coyote, and even today in the remaining backwoods the maxim persists that the only good varmint is a dead one. …

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

Set stocking of sheep at increased stocking rates is rapidly becoming popular with farmers in the agricultural areas of Western Australia.

But will set stocking increase soil erosion hazards? It should do just the reverse, according to Soil Conservation Adviser J. E. Watson, B.Sc, who claims that set stocking has a place in soil conservation farming.

Pigs Have A Place In The Dairying Areas, P Mcnamara

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

Pig-keeping could become a much more important feature on South-West dairy farms in the future with the enterprise as a definite farm-unit having a considerable effect on income.

There are indications also that the collection of bulk skim milk and whey for pig feeding will increase in the future. This could make way for the efficient specialist operating large pig raising units close to the source of supply.

In this article. Pig Husbandry Adviser P. McNamara, B.A. (Cantab.) examines pig-keeping in the South-West and makes suggestions on the part that pigs can play on the modem dairy farm.

Recent Advances In Lupinosis Research, M R. Gardiner

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

BECAUSE of the important role which lupins play in light land development, flock losses from the effects of lupinosis must inevitably continue to be a matter of serious concern.

However, research carried out during the last four years has considerably advanced our knowledge of the fundamental nature of this disease and of the way in which it may be prevented or controlled.

United States Fish and Wildlife Service: Publications

North American Trichodina from Carassius auratus, Lepomis cyanellus, L. macrochirus, Micropterus salmoides, and Rhinichthys atratulus have been studied by the silver-impregnation method and compared with European species. T. reticulata Hirschmann and Partsch, 1955, and T. (Foliella) subtilis Lorn, 1959, originally described from European goldfish, are herein recorded from North America also. T. fultoni Davis, 1947, from Lepomis cyanellus, Micropterus salmoides, and Rhinichthys atratulus is redescribed, and T. domerguei f. magna Lorn, 1961, described from European tench and gudgeon, is considered a synonym.

Genotype And Variability In Dairy Lactation Records, L. Dale Van Vleck, G. R. Barr

Department of Animal Science: Faculty Publications

In quantitative genetics, the variation of individuals within genetic groups is commonly attributed to environment. The assumption is then made that the environmental variances are similar from one group to another. Complications arise in the application of selection index theory when this assumption is not made. The results reported here indicate that in a population of dairy records, the environmental variance is not similar from one genetic group to another. Johnson (1945) and Wadell, Van Vleck and Henderson (1960) found similar results with fewer data.
