University of Nebraska-Lincoln Extension: Historical Materials

Spring and summer black stem of alfalfa, their causes, symptoms, and control are discussed.

Of the two black stem diseases found in the central and northern Great Plains, spring black stem predominates summer black stem. Both are damaging when weather conditions favor their development. Although their symptoms differ, each causes spotting and darkening of stems and spotting of leaves.

G80-537 Reproductive Trace Anatomy And Physiology Of The Cow, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

Knowledge of basic reproduction will help a producer to obtain higher conception rates when using estrous synchronization and/or artificial insemination. The reproductive performance of a cow herd has a great influence on the income and profit realized. A good understanding of the anatomy and physiology of the cow's reproductive system is, therefore, beneficial for successful management. Knowledge of basic reproduction will help a producer to obtain higher conception rates when using estrous synchronization and/or artificial insemination. It will also allow for a better understanding of pregnancy examinations, reproductive diseases and calving difficulty problems.

G80-536 Reproductive Trace Anatomy And Physiology Of The Bull, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

Understanding the anatomy and physiology of the bull's reproductive tract is beneficial for proper management. Good reproductive performance of a bull is necessary to obtain a high percent calf crop. A bull must be fertile and capable of servicing a large number of cows during a short breeding season for optimum production. Understanding the anatomy and physiology of the bull's reproductive tract is beneficial for proper management. A basic knowledge of the reproductive system will also help the producer to understand fertility examinations, reproductive problems and breeding impairments.

G80-495 Managing Two-Year-Old Beef Heifers (Calving - Rebreeding), Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the nutrition and management practices recommended for beef heifers during precalving, calving, and early lactation periods. Proper development of replacement heifers has a great influence on the success of calving and rebreeding them as two-year-olds. NebGuide G80-493, Developing Replacement Beef Heifers (Weaning-Breeding), points out that proper selection, adequate nutrition, and judgment in sire selection are all important management factors for developing heifers into high producing cows. With good management before breeding, a high percentage of heifers should be bred early in a short breeding season. Heifers should be pregnancy checked and the open ones culled. Thereafter, the …

Propagation Of Quaking Aspen (Populus Tremuloides Michx.) From Root Cuttings, Karen Elizabeth Burr

Aspen Bibliography

Lateral root cuttings were collected at five quaking aspen (Populus tremuloides Michx.) clones in Larimer County, Colorado on October 2, 1977 and May 30, 1978. The October 1977 root cuttings were stored eight months in air-tight plastic bags at 0 to 4°C. On June 1, 1978 the stored (October 1977) and the fresh (May 1978) root cuttings were planted in a greenhouse propagation bench. All sprouts that developed were allowed to grow on half of the 10-cm long root cuttings randomly selected as controls. On the remaining half of the root cuttings, designated pruned, all but the tallest sprout were …
