Many fanners feed large amounts of grain to their weaners over summer and autumn, in the belief that this is necessary for high lifetime production.

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

Think carefully before buying proprietary "shotgun" licks, warns Animal Nutrition Officer Dr. L C. Snook in this article.

Parameters For Milk Yield And For Percents Of Ash, Dry Matter, Fat And Protein In Sows, W. G. Pond, L. Dale Van Vleck, D. A. Hartman

Department of Animal Science: Faculty Publications

Milk was collected separately by machine from four to six glands on nine Yorkshire and Berkshire sows 2 or 3 days after farrowing and at weekly intervals throughout 6 weeks of lactation. Milk yield was measured following intramuscular injection of oxytocin, and the percent of ash, dry matter, fat and protein in the milk from each gland was determined. The average milk yield per gland, following a 1-hour period during which the pigs had been removed from the sow reached a peak of 74.6 gm. 3 weeks after farrowing. The ash content was 0.79% 2 or 3 days after farrowing, …

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 …

Interaction Between The Parameters Of Hydrostatic Pressure And Temperature On Aspartase Of Escherichia Coli, Roger D. Haight, Richard Y. Morita

Papers in Microbiology

HAIGHT, ROGER D. (University of Nebraska, Lincoln) AND RICHARD Y. MORITA. Interaction between the parameters of hydrostatic pressure and temperature on aspartase of Escherichia coli. J. Bacteriol. 83:112-120. 1962.-The data obtained from studies of an aspartase preparation and aspartase in cells of Escherichia coli indicate that there is an interaction between the parameters of hydrostatic pressure and temperature. Pressure was found to decrease aspartase activity at 45 C and lower in vitro and below 53 C in vivo, thereby indicating that when the enzymesubstrate complex is formed there is an increase in molecular volume which is counteracted by pressure. Above …
