Monitoring Cattle Behavior And Pasture Use With Gps And Gis, L. W. Turner, M. C. Udal, B. T. Larson, S. A. Shearer
Monitoring Cattle Behavior And Pasture Use With Gps And Gis, L. W. Turner, M. C. Udal, B. T. Larson, S. A. Shearer
Management and Monitoring of Farm Animals Collection
Precision agriculture is already being used commercially to improve variability management in row crop agriculture. In the same way, understanding how spatial and temporal variability of animal, forage, soil and landscape features affect grazing behavior and forage utilization provides potential to modify pasture management, improve efficiency of utilization, and maximize profits. Recent advances in global positioning system (GPS) technology have allowed the development of lightweight GPS collar receivers suitable for monitoring animal position at 5-min intervals. The GPS data can be imported into a geographic information system (GIS) to assess animal behavior characteristics and pasture utilization. This paper describes application …
Bunk Attendance Of Feedlot Cattle Monitored With Radio Frequency Technology, D. J. Gibb, T. A. Mcalllister, C. Huisma, R. D. Wiedmeier
Bunk Attendance Of Feedlot Cattle Monitored With Radio Frequency Technology, D. J. Gibb, T. A. Mcalllister, C. Huisma, R. D. Wiedmeier
Management and Monitoring of Farm Animals Collection
Bunk attendance of 72 feedlot cattle (412 ± 23.6 kg) was monitored for 86 d using radio frequency technology. Late morning and late afternoon were confirmed as primary ad libitum feeding periods. The system detected differences (P < 0.005) in feeding behaviour in response to level of feeding and frequency of meals.
Shade Management In Subtropical Environment For Milk Yield And Composition In Holstein And Jersey Cows, R. J. Collier, R. M. Eley, A. K. Sharma, R. M. Pereira, D. E. Buffington
Shade Management In Subtropical Environment For Milk Yield And Composition In Holstein And Jersey Cows, R. J. Collier, R. M. Eley, A. K. Sharma, R. M. Pereira, D. E. Buffington
Management and Monitoring of Farm Animals Collection
Forty-eight cows were assigned randomly to shade (15 Holsteins, 8 Jerseys) or no shade (16 Holsteins, 9 Jerseys) for 102 days beginning 12 June 1977 to examine effects of solar heat load on milk yield and composition. Rectal temperatures, respiration rates, and rumen contractions/min were monitored between 1200 and 1700 h on 20 randomly selected days. Morning and evening milk weights were recorded daily. Once weekly, morning and evening milk samples were collected from each cow and analyzed for fat, protein, acidity, freezing point depression, and somatic cell number. Black Globe temperature, rectal temperature, and respiration rate were elevated in …
