Progress 07/01/99 to 06/30/05
Outputs
Data from completed trials were analyzed and publications were submitted to appropriate venues. This project has supported research work on bovine respiratory disease, feedlot cattle feed intake, and improving reproductive performance in at risk cows. Significant effort in the area of Beef Quality Assurance (BQA) training was central to this project and has been very successful across the state. Extensive training materials have been developed for this program. These materials include written training manuals, compact disks and video tapes, a searchable DVD, several Powerpoint presentations, and a website to serve the BQA programs of Louisiana and Mississippi is under construction. This BQA effort will continue to play a central role in our efforts in the future.
Impacts
Beef quality issues continue to play a central role in the discussion of consumer acceptance of beef products. Quality defects cost the beef industry millions of dollars per year. Approximately 75 presentations in front of producer and veterinary groups dealing with BQA have been given over the lifespan of this project. These presentations have been attended by anywhere from 15 to 400 producers, veterinarians, and extension personnel. It is estimated that we have reached a minimum of 5,000 cattlemen, veterinarians, and extension personnel with our BQA training efforts. The development and use of electronic training tools will continue to be emphasized as we move this program into the future. While progress has been made, we need to continue to reach more cattlemen and veterinarians, as well as reinforce their previous training. Reproductive performance has the greatest impact of any management area on producer profitability. Cows that fail to conceive or conceive late
in the breeding season represent a multi-million dollar loss for the beef cattle industry. Estrus synchronization protocols enable producers to get more cows bred in a shorter period of time. This improves the output of the operation and their profitability as well. Bovine respiratory disease is the single most expensive disease entity to strike at stocker and backgrounding operations in the southeast. Metaphylaxis has become an industry standard for receiving protocols in these operations. Our research efforts in this area have helped to better define this management practice.

Progress 01/01/04 to 12/31/04
Outputs
Data from completed trials were analyzed and publications were submitted to appropriate venues. Significant effort in the area of Beef Quality Assurance was continued across the state. There were six meetings given for cattlemen or college students that dealt specifically with Beef Quality Assurance. The first draft of a new set of BQA training materials has been completed and is being reviewed. Construction of a BQA website to enhance our ability to reach and train cattlemen and veterinarians is currently under way. A trial involving the use of an estrus synchronization protocol to improve reproductive performance in late calving cows was completed. An abstract from this trial has been accepted for publication in 2005.

Progress 01/01/02 to 12/31/02
Outputs
Data from completed trials was analyzed and publications were submitted to appropriate venues. Significant effort was invested in the continued implementation of the Mississippi Beef Quality Assurance program this past year. Seven educational programs on BQA were presented to Mississippi cattlemen across the state and a continuing education program was presented to Mississippi practitioners. A trial was completed that dealt with estrus synchronization methods in replacement beef heifers and another one was submitted to look at the effects of different forms of vitamin E supplementation on immune response in calves. Another trial is being designed to look at the economic differences in feedlot performance between preconditioned calves and sale barn origin calves.
Impacts
Beef quality defects cost the cattle industry millions of dollars each year. Continued education of producers and veterinarians will emphasize the need for improved management in order to decrease the magnitude of these losses. Bovine respiratory disease (BRD) is a common occurrence in southeastern calves upon their arrival at the feed yard. Due to the losses associated with this complex, southeastern calves are discounted heavily compared to calves from other regions of the country. Documenting the economic differences between sale barn and preconditioned calves will help producers, veterinarians, and cattle feeders make better decisions in management. Estrus synchronization protocols will also help cow/calf producers increase their efficiency by making artificial insemination more applicable. This offers an opportunity to improve genetic selection over the long-term.

Progress 01/01/01 to 12/31/01
Outputs
Data from completed trials was anlayzed and publications were submitted to appropriate venues. Significant effort was invested in the continued implementation of the Mississippi Beef Quality Assurance program this past year. These materials were presented to hundreds of producers by utilization of demonstrations, distance education programs, and printed matter. Plans were also made to include continued training as part of the Misssissippi Cattlemen's Association Convention. A trial was completed that dealt with the response of high-risk salebarn stocker calves to metaphylaxis strategies. Another trial was initiated to look at the effects metabolic indicators on dairy cow fertility.
Impacts
Beef quality defects cost the cattle industry millions of dollars each year. Continued education of producers and veterinarians will emphasize the need for improved management in order to decrease the incidence of these defects. Bovine respiratory disease (BRD) is the most costly disease complex facing the cattle industry in this country. Exploring strategies to minimize the effects of BRD on stocker operations will decrease input costs and increase cattle performance. Both veterinarians and producers should find this information useful. Reproductive performance in dairy herds has a large impact on profitability. Using metabolic indicators to profile overall herd health has the potential to be an inexpensive means of monitoring and improving reproductive efficiency.
