OUTPUTS: Data was collected and input for analysis. Parentage analysis of calves was conducted on all animals within unknown sires. The DNA repository grew to around 5600 samples with complete pedigree and performance information. Our Ranch Explorer's Field Days were a great success with nearly 600 participants attending during the duration of this study. Several students at both the college and high school levels were given hands-on experience handling and caring for beef cattle. Ranch personnel were actively involved in the local, state, and national cattlemen activities. We also worked closely with the Native American tribes in Arizona both in management techniques and workshops. PARTICIPANTS: David W. Schafer - PI and Resident Director of the ranch.

Progress 01/01/04 to 12/31/04
Outputs
Data is being entered into the database program and hopefully some preliminary analysis can begin soon relative to each breed's performance. We began the process of introducing the Tuli breed into the evaluation program this past year. The first calves will be produced in 2005. The DNA repository contains around 3,400 samples with complete pedigree and performance information on the majority of the samples. Our annual Ranch Explorer's Field Day was held again this year with nearly 300 participants attending. We continue to work with local high schools to get them hands-on experience handling and caring for beef cattle. Ranch personnel are actively involved in local, state and national cattleman activities.

Outputs
Data is currently being input into the new database management program and work will soon begin on the development of reports within the program. Once the data is input and some reports have been developed, work will begin on developing the web access portion of the database. A composite consisting of 50% Tuli and 50% Wagyu (Waguli) was introduced into the breeding program this year. A donation of three Waguli bulls and six heifers was received and integrated into the breeding program for evaluation. Parentage verification has been completed on all calves born from 2000 to 2003 so subsequent data analysis can now begin. Our annual Ranch Explorers Field Day was held again this year with nearly 200 participants. We continue to work with local high schools to get them hands-on experience handling and caring for beef cattle. Ranch personnel have actively participated in various local, state and national cattleman activities.

The database management project is back on track. Programming is currently in progress and a server has been purchased. Performance and carcass data continue to be collected on all animals produced from the Ranch and DNA has been collected and stored for future use. Parentage verification is in progress for all calves born on the ranch to date. Due to severe drought conditions, the annual Ranch Explorers Day had to be cancelled but the ranch did host several student and community group tours throughout the year. Ranch personnel have actively participated in various local, state and national cattleman association activities.

The database management program suffered a minor set back due to personnel changes and as yet remains unfinished. A second group of CGC composite (50% Red Angus, 25% Charolais, 25% Tarentaise) heifers was introduced into the herd during 2001 and the first calves were weaned from the first introduced group. Performance and carcass data continue to be collected on all animals produced from the ranch and DNA has been collected and stored for future use. Parentage verification for all 2000 and 2001 calves was initiated in the fall of 2001. The ranch hosted a research field day in June, 2001 and a Ranch Explorer's Day in August, 2001. Ranch personnel have actively participated in various local, state and national cattleman association activities.

Programming is nearing completion on the database management system and we will soon be working on developing reports and inputting data. The CGC composite (50% Red Angus, 25% Charolais, 25% Tarentaise) was introduced into the herd this year with 2 year old heifers calving on the ranch and the purchase of an additional 70 head of weanling heifers to be developed and bred in Spring, 2001. Performance and carcass data continue to be collected on all animals produced from the ranch and DNA has been collected and stored for future use. The V Bar V Ranch hosted the annual Composite Cattle Breeders International Alliance and Ranch Explorers Day in August, 2000.
