The objective of this randomized clinical trial was to determine if an intervention with colostrum replacer (CR; Premolac Plus, Zinpro; 125 g/d fed for 3 d) or a placebo milk replacer (Cows Match, Land O'Lakes Inc.; 125 g/d for 3 d) following a triggered alarm could ameliorate disease bouts in dairy calves. The alarm was set to detect negative deviations of milk intake (20% reduction) or drinking speed (30% reduction) in relation to a calf's 12-d rolling average feeding behavior. Calves were enrolled on this study (n = 42 CR, n = 42 placebo) when they triggered an alarm from …

The present invention provides materials and methods related to causing insect resistance in plants. Specifically, the present invention provides nucleic acid compounds which encode a teratocyte secreted protein (TSP) which is capable of causing inhibition of growth and developmental arrest in Lepidoptera larvae. Cells and plants (including plant parts, seeds, embryos, etc.) comprising the nucleic acid compounds are also within the scope of the present invention. The present invention also provides amino acid compounds encoded by the nucleic acid compounds of the present invention, as well as methods to induce larval developmental arrest, methods to produce the nucleic acid and …

As a part of a National Pork Producers Council educational program, our research and extension team at the University of Kentucky was linked with an independent commercial swine producer to test the NCPIG model against observed commercial on-farm data. This experience provided improved information for model development as well as increased producer insight into the data input needs and potential benefits of modeling. Detailed production information comparisons between the NCPIG model and producer data are presented for summer time conditions to assess the validity of the NCPIG model for simulation of grow-finish swine performance. Results demonstrated that the NCPIG model …
Nitrogen Source Effects On The Growth And Development Of Burley Tobacco Transplants In The Float System, Robert C. Pearce, Gary K. Palmer
Nitrogen Source Effects On The Growth And Development Of Burley Tobacco Transplants In The Float System, Robert C. Pearce, Gary K. Palmer
Agronomy Notes
During the spring of 1996, many tobacco producers used a water soluble 20-10-20 fertilizer in their float beds, only to have to throw out the stunted sickly plants that resulted, and start over. The fertilizer that caused the problems turned out to have 100% of the nitrogen (N) as urea-N. It was hypothesized that the poor growth was related to with the conversion of the urea-N to other forms of N. There have been numerous other cases where producers using fertilizers high in urea-N or ammonium-N (NH4-N) have had problems with stunted plant growth. Further study of nitrogen transformations is …
Differential Black Walnut Growth On A Recommended Soil Map Unit: Investigation Of Related Soil Chemical And Physical Properties, David C. Ditsch, Jeff Stringer, D. Mcintosh
Differential Black Walnut Growth On A Recommended Soil Map Unit: Investigation Of Related Soil Chemical And Physical Properties, David C. Ditsch, Jeff Stringer, D. Mcintosh
Agronomy Notes
Black walnut (Juglans nigra L.) is one of the best known and most valuable trees in Kentucky. However, due to its high value, the species has been aggressively harvested from natural stands, creating a limited supply of quality black walnut trees. Many landowners recognize this as an investment opportunity and have placed small tracts of unused land into black walnut production.
Growth Of Early Maturing Soybean, M. V. Kane, Colleen C. Steele, Larry J. Grabau
Growth Of Early Maturing Soybean, M. V. Kane, Colleen C. Steele, Larry J. Grabau
Agronomy Notes
Production of early maturing soybean varieties has grown in popularity across the southeastern US in recent years. Many growers in Mississippi, Arkansas, and Texas have seen this system as a way to avoid late season drought. However, several Kentucky growers have had good success with the use of Maturity Group (MG) II soybeans in the recent seasons which had generally good rainfall patterns. Some growers are glad to get competitive yields from MGII soybean while gaining the opportunity to harvest some of their soybean acreage before corn is ready to harvest.
Growth, Yield, And Efficiency Of Potassium Fertilizer Use In Burley Tobacco Production, J. L. Sims, William O. Thom, Kenneth L. Wells, J. D. Clark
Growth, Yield, And Efficiency Of Potassium Fertilizer Use In Burley Tobacco Production, J. L. Sims, William O. Thom, Kenneth L. Wells, J. D. Clark
Agronomy Notes
For many crops, band placement of fertilizer offers agronomic, economic, and environmental advantages over commonly used preplant broadcast applications. Drill banding most of the nitrogen (N) fertilizer 12 inches to both sides of the row for tobacco shortly after transplanting greatly aIleviates manganese toxicity and other nutrient imbalances, improves early growth and yield, and offers increased efficiency of N use. Nitrogen fertilizers applied after transplanting are less likely to be leached during excess rainfall events that commonly occur in April and early May in Kentucky.
Growth Response Of Kenhy Fescue To Nitrogen Fertilizer, Kenneth L. Wells, Robert C. Buckner, George Armstrong, Paul Gray, C. E. Wyatt
Growth Response Of Kenhy Fescue To Nitrogen Fertilizer, Kenneth L. Wells, Robert C. Buckner, George Armstrong, Paul Gray, C. E. Wyatt
Agronomy Notes
Kenhy fescue is a new, improved variety of tall fescue which has recently been released by the University of Kentucky Agricultural Experiment Station and the U.S.D.A. Agricultural Research Service (see University of Kentucky publication AGR-60, "Kenhy A New Tall Fescue Variety"). Seed of this variety should become available to farmers in limited quantities in the summer 1977. The purpose of this report is to provide information on how this newly developed fescue variety produces as affected by time and rate of nitrogen application.
