Pollination Cycles And Pollen Dispersal In Relation To Grass Improvement, Melvin D. Jones, L. C. Newell
Pollination Cycles And Pollen Dispersal In Relation To Grass Improvement, Melvin D. Jones, L. C. Newell
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The plant breeder is initially concerned with gaining a knowledge of the breeding behavior of his plant materials in order that improvement may be undertaken effectively. It is important to know the different characteristic pollination habits of these plants. To develop and apply techniques applicable to the improvement of a given grass crop, it is desirable to know the time of day and the number of days that the grass sheds pollen. The effects of temperature, humidity, light, and wind on pollination must be considered. Once superiority of germplasm is obtained, the most important consideration is the maintenance of this …

Pig Typhus (Salmonellosis Suis), L. Van Es
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Salmonellosis suis or pig typhus, also designated as pig typhoid, infectious necrotic enteritis, or "necro," is an infectious disease among young pigs. It constitutes a major factor in the mortality of juvenile swine, and as such must be regarded as a more or less perennial hazard in swine production. Infectious necrotic enteritis caused by Salmonella suipestifer is the subject of the present publication.
The Utilization Of Food Elements By Growing Chicks. Xi. A Comparison Of Ground Wheat And Ground Rye In Rations For Growing Chicks, C. W. Ackerson, W. E. Ham, F. E. Mussehl
The Utilization Of Food Elements By Growing Chicks. Xi. A Comparison Of Ground Wheat And Ground Rye In Rations For Growing Chicks, C. W. Ackerson, W. E. Ham, F. E. Mussehl
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. The effect of replacing the shorts and bran of a standard ration by ground wheat or ground rye was studied with two lots of newly hatched chicks. 2. Comparisons were made on the basis of equal intakes of dry matter and nitrogen by all chicks. 3. The wheat-fed lot made a significantly greater gain than the rye-fed lot. 4. Several cases of curled-toe paralysis occurred in the two lots, and a tendency to cannibalism appeared in the rye-fed lot.
The Utilization Of Food Elements By Growing Chicks. X. A Comparison Of Open-Pollinated And Hybrid Corn In A Ration For Growing Chicks, C. W. Ackerson, W. E. Ham, F. E. Mussehl
The Utilization Of Food Elements By Growing Chicks. X. A Comparison Of Open-Pollinated And Hybrid Corn In A Ration For Growing Chicks, C. W. Ackerson, W. E. Ham, F. E. Mussehl
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. The effect of replacing the open-pollinated corn with hybrid corn in an otherwise complete ration was studied in a growth and body analysis experiment with two lots of newly hatched chicks. 2. The pelleted rations were consumed in identical amounts by all chicks of both lots. 3. There were significant differences in the growth rate of the chicks at the end of a six-weeks feeding trial in favor of the lot fed open-pollinated corn.
Distillers' By-Products And Soybean Meal In Dry Calf Starters For Calves On Limited Quantities Of Milk, H. P. Davis, G. W. Trimberger
Distillers' By-Products And Soybean Meal In Dry Calf Starters For Calves On Limited Quantities Of Milk, H. P. Davis, G. W. Trimberger
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Whole milk is recognized to be very satisfactory as the principal source of nutrients for young growing calves. But the price of milk and its importance as food for human beings has tended to introduce the use of substitutes. Skim milk has been demonstrated to be a satisfactory substitute when fed with grain after the first few weeks of feeding; but since skim milk, too, has become of increased usefulness for human nutrition, this experiment, one of a series, was designed to determine whether or not combinations of various grains, when fortified with vitamins, could be substituted for the solids …
Influence Of Food Plants On Fecundity, Larval Development And Abundance Of The Tuber Flea Beetle In Nebraska, Roscoe E. Hill
Influence Of Food Plants On Fecundity, Larval Development And Abundance Of The Tuber Flea Beetle In Nebraska, Roscoe E. Hill
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Laboratory and field tests were conducted to determine the effects of different food plants on fecundity, adult longevity and larval development of the tuber flea beetle, Epitrix tuberis Gentner. All food plants tested were those upon which the overwintered beetles commonly feed in the spring following emergence from hibernation.
