Irrigation And Fertilization Practices For Seed Production From Established Stands Of Side-Oats Grama, D. E. Smika, L. C. Newell

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The objectives of this study of grass seed production were to determine the response of an established stand of a warm-season grass to irrigation and fertilizer practices with regard to the specific practices needed to produce maximum quantity of adequate quality seed per acre. Side-oats grama was chosen for the study because of the availability of adapted varieties.

Biochemical Changes During The Growth Of Fungi: Ii. Ergosterol And Fatty Acids In Penicillium Atrovenetum, David Gottlieb, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Changes in the lipid constituents of Penicillium atrovenetum were studied during the growth and development of this fungus. The stages in development, as measured by the dry weight, were divided into four phases: lag, log, stationary, and death. The total fatty acids on a dry-weight basis increased from a minimum in the spores to a maximum near the end of the log phase of growth. The major fatty acids were palmitic, stearic, oleic, and linoleic. Myristic, pentadecanoic, palmitoleic, heptadecanoic, linolenic, arachidic, and heptadecenoic acids, together with two unidentified components, were also present in the fatty acid fraction. Compared to ungerminated …

Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson

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

TRADITIONALLY, wheatbelt farmers have looked upon sheep as being subsidiary, or at best, complementary to their main activity, wheat growing.

Because there has been a mistaken belief that clover would not grow, these farmers have depended upon native grasses and crop remains (stubble) for sheep feed, a practice which has put a limit to the number of sheep a property could support.

Nodulation Of Legumes On New Light Land. 3. The Effect Of Rogor Seed Treatment On Legume Nodulation, O M. Goss, W. A. Shipton

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

SEED treatment with systemic insecticides is widely used for the control of insect pests. However, when seed inoculation is necessary for pasture establishment, seed treatment with insecticide is not advisable.

A field experiment conducted at Badgingarra Research Station in 1964 showed that the systemic insecticide Rogor was very damaging to the applied rhizobia even when the treated seed was held for a month before inoculation.

Rearing Dairy Calves, R A. Bettenay

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

ON Western Australian dairy farms the wastage rate of dairy cows is probably more than 20 per cent, and this, coupled with the tendency towards bigger herds, means that well over half of the heifer calves born should be reared for herd replacements.

Calfhood Diseases. 1. Gastro-Intestinal Diseases, M R. Gardiner

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

CALFHOOD disease may be divided for convenience into three main categories:

• Those affecting the gastro-intestinal tract, including diseases of an infectious nature and those arising as a result of infestation by worms (parasitism).

• Those affecting the respiratory system, including lungworms.

• Those resulting from nutritional deficiencies, especially vitamins and minerals.

Effect Of Ferrous Fumarate In The Lactation Diet On Sow Milk Iron, Pig Hemoglobin And Weight Gain, T. L. Veum, J. T. Gallo, L. Dale Van Vleck, J. K. Loosli

Department of Animal Science: Faculty Publications

Two experiments involving 22 litters were conducted to study the effects of adding ferrous fumarate to the lactation diet on iron level of sow’s milk and on weight gains and hemoglobin levels of suckling pigs. Ferrous fumarate was not effective in increasing iron content of milk, when added to the lactation diet at a level of 1984 mg. of iron per kg. The increase in hemoglobin level observed at 24 days in Experiment I and at 21 days in Experiment II, in litters nursing sows fed ferrous fumarate, was due to the pigs’ obtaining a source of iron from the …

Response Of Sheep And Swine To Treatments For Control Of Ovulation, P. J. Dziuk

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

Control of the estrous cycle is essential to precise research in gamete and zygote physiology and could be useful in animal husbandry. The conception rate in sheep during the breeding season following treatments to control ovulation has varied from about normal (Dauzier, 4; Robinson, 20; Evans et al., 9; Lamond and Bindon, 17; Brunner et al., 3; Hinds et al., 15), to distressingly low levels in other cases (Braden et al., 2; Davies, 5; Lamond, 16). Treatments during the anestrous season have given a variable response but usually only 30 to 50 percent of ewes lamb (Gordon, 13; 14).
