Optimum Utilization Of Alfalfa In Horses, Stephen G. Jackson
Optimum Utilization Of Alfalfa In Horses, Stephen G. Jackson
Kentucky Alfalfa and Stored Forage Conference
When considering forage utilization in horses one must consider principally two factors; 1) forage quality and 2) the relationship between voluntary intake of a forage and a particular class of horses nutrient needs.
Optimum Utilization Of Alfalfa In Sheep Rations, G. L.M. Chappell
Optimum Utilization Of Alfalfa In Sheep Rations, G. L.M. Chappell
Kentucky Alfalfa and Stored Forage Conference
The unique qualities of alfalfa as a forage afford the progressive sheep producer many opportunities to develop efficient sheep feeding programs. As a grazed sward, as hay or silage, alfalfa can be utilized in a variety of ways. The following points should be considered in developing programs using alfalfa.
Maximizing Alfalfa Hay In Beef Feeding Programs, W. Roy Burris, Garry D. Lacefield
Maximizing Alfalfa Hay In Beef Feeding Programs, W. Roy Burris, Garry D. Lacefield
Kentucky Alfalfa and Stored Forage Conference
Beef cattle comprise the largest group of forage and hay users in Kentucky. Because of their ability to utilize large amounts of low quality roughage, they are sometimes relegated to that role exclusively. There are many instances in beef production when alfalfa hay can be utilized because of its high protein content. The value of alfalfa hay in a beef operation can be estimated by the protein and energy that it furnishes.
Maximizing Alfalfa In Dairy Feeding Programs, Dan O. Riddell
Maximizing Alfalfa In Dairy Feeding Programs, Dan O. Riddell
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is an excellent feed for dairy cows. When used properly, alfalfa can help cut cost of production and increase level of production. However, like everything else, the feeding of alfalfa needs to be managed to maximize efficient production. There are three key steps involved in maximizing alfalfa in a dairy feeding program. These are:
- harvest alfalfa at the proper stage of maturity
- know what the alfalfa contains and feed accordingly
- get the alfalfa to the cows that need it.
Hay Quality Evaluation, William C. Templeton Jr.
Hay Quality Evaluation, William C. Templeton Jr.
Kentucky Alfalfa and Stored Forage Conference
During the last few years there have been several developments related to hay quality evaluation and marketing. In this presentation I shall briefly review these and indicate some of the implications for producers, vendors, purchasers and users of alfalfa hay.
Reducing Hay Losses — From Standing Crop Through Storage, Michael Collins
Reducing Hay Losses — From Standing Crop Through Storage, Michael Collins
Kentucky Alfalfa and Stored Forage Conference
Alfalfa management for maximum economic productivity is quite complex. Many factors ranging from cultivar selection and establishment to storage and feeding must be considered. In some cases these factors, yield and quality of a particular cutting of forage for example, are negatively correlated. Following good establishment of an adapted cultivar, cutting management has important effects on forage yield, forage quality, stand persistence, weed encroachment and other important responses. Maturity stage at the time of cutting greatly affects quality. After cutting, hay curing, packaging and storage conditions also affect quality. Clearly, in order to achieve the optimum combination of yield and …

No-Till Alfalfa Establishment, Garry D. Lacefield
Kentucky Alfalfa and Stored Forage Conference
The topic ''No-till Alfalfa" was discussed at the V Annual Alfalfa Conference this past February in Elizabethtown. At that conference, we reported results of demonstrations that had been conducted along with preliminary results of some of the research underway. In the presentation today, I would like to review some of the opportunities for no-till alfalfa and discuss some additional research results.
Herbicides For Alfalfa Weed Control, William W. Witt
Herbicides For Alfalfa Weed Control, William W. Witt
Kentucky Alfalfa and Stored Forage Conference
Numerous herbicides are available for controlling weeds in pure or mixed stands of alfalfa. In addition, these herbicides can be applied at different times and stages of alfalfa growth -from prior to planting to actively growing alfalfa to dormant applications during the winter. To be confident of achieving the desired weed control, it is important to apply alfalfa herbicides at the proper growth stage and rate.
The following tables contain information pertinent to proper utilization of the herbicides to obtain maximum weed control.

A Dna Sequence Analysis Program For The Apple Macintosh, Robert H. Gross
A Dna Sequence Analysis Program For The Apple Macintosh, Robert H. Gross
Dartmouth Scholarship
This paper describes a new set of programs * for analyzing DNA sequences using the Apple Macintosh computer, a computer ideally suited for this kind of analysis. Because of the Macintosh interface and the availability of high quality software-only speech synthesis, these programs are truly easy to use. Instead of typing in commands, the user directs the program by making selections with the mouse, thereby eliminating most typographical and syntax errors. Output options are selected by “pressing buttons” and then clicking “OK” with the mouse. DNA sequences are confirmed by having the program speak them. The high resolution graphics on …

Deep Flow Variability In Central Drake Passage, John M. Klinck, Eileen E. Hofmann
Deep Flow Variability In Central Drake Passage, John M. Klinck, Eileen E. Hofmann
CCPO Publications
A rotary empirical orthogonal function analysis of the currents measured in central Drake Passage during DRAKE 79 shows that the deep (2500 m) flow has the same spatial and temporal structure as the flow at 500 m, suggesting that current variability in this region penetrates to the bottom. However, comparison of the time amplitude of the corresponding modes indicates that the variability of the 2500 m flow resulting from north to south shifts in the location of the Polar Front lags that at 500 m by one to three days. This implies that the Polar Front slopes to the east …

Continued Ddt Persistence In Mississippi River Delta Streams: A Case Study, Stephen A. Sewell, Luther A. Knight Jr.
Journal of the Arkansas Academy of Science
Fish samples representative of several trophic levels were taken from the Wolf and Loosahatchie Rivers of western Tennessee during the early 1980s. Results indicate that DDT, with metabolites DDD and DDE, remains common in fish tissues in these areas and approaches the levels recommended as maxima for human consumption by the U.S. Food and Drug Administration. Samples of top carnivores and forage fishes, particularly the gizzard shad, Dorosoma cepedlanum, commonly exceeded 500 ppb DDE. The results are discussed in light of sediment disturbing activities.

With new legislation to replace the Cruelty to Animals Act 1876 near at hand, the powerful vested interest groups whose profits and livelihood depend on laboratory animals are stepping up their campaigns to ensure the survival of vivisection. Have the benefits really been so great, and can vivisection achieve major advances in our present state of health?

The anatomical structure of the secondary xylem (wood) of trees varies with location in the tree. The size, shape, and distribution of cell types varies not only between locations (i.e., stem vs. branch vs. root), but also within an annual ring or across annual rings at a given cross-sectional plane.
