I. The trypsin inhibitor contained in one-half of a lot of soybean meal was destroyed by autoclaving at 15 pounds for 20 minutes. 2. This portion of the meal when fed at a level of 24 per cent to newly hatched poults gave a significantly greater gain in five weeks than did an equal amount of meal in which the inhibitor had not been destroyed. 3. The difference in growth is attributed to the destruction of the trypsin inhibitor.

It is the purpose of this study to determine whether under conditions of routine handling in artificial breeding associations there is a decline in semen fertility from day to day and also to determine the magnitude of this decline. Tabulation of such data will not only be of value in determining the effect of frequent semen collection on the over-all artificial breeding results but will also serve as a basis of comparison in investigational work directed toward increasing the efficiency of artificial breeding.

The purpose of this investigation was primarily to determine what effects rate and method of application of residues have on the distribution of microorganisms within the plow-depth layer of soil.
Breeding Efficiency In Dairy Cattle From Artificial Insemination At Various Intervals Before And After Ovulation, George W. Trimberger
Breeding Efficiency In Dairy Cattle From Artificial Insemination At Various Intervals Before And After Ovulation, George W. Trimberger
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The length of estrus and the time of ovulation were determined for 46 heifers and 86 cows of the Ayrshire, Guernsey, Jersey, and Holstein breeds by testing for end of estrus and ovulation at 2-hour intervals. Services were given by artificial insemination at various intervals before and after ovulation to determine the influence of this factor on the rate of conception. No significant breed or seasonal differences were found for length of estrus and ovulation time after end of estrus among the four dairy breeds represented in the experiment.
