Kansas Agricultural Experiment Station Research Reports

Kansas State University is pleased to present the 2017 Dairy Research Report of Progress. We continue to watch the Kansas dairy industry grow, and in 2016 our state ranked 10th for largest growth in total milk produced. During the past 5 years (2011 to 2016), total milk production in Kansas has increased by 29%; the number of cows by 18%; and annual pounds of milk per cow by 1,785. Therefore, the Kansas dairy herd is not only growing, but is becoming more productive and efficient. At the end of 2016, Kansas ranked 13th nationally in milk yield per cow ...

Development Of A Berry Processing Score For Sorghum Silage, J. R. Johnson, J. P. Goeser, Michael Brouk Jan 2016

Development Of A Berry Processing Score For Sorghum Silage, J. R. Johnson, J. P. Goeser, Michael Brouk

Kansas Agricultural Experiment Station Research Reports

This study was done in an effort to develop a berry processing score (BPS) for sorghum silage, similar to the kernel processing score (KPS) currently used for corn silage. Sorghum silage samples were collected from 3 dairies in Kansas and processed in the Grain Science & Industry grain processing laboratory at Kansas State University using one of four different roll gap settings to give four differently processed samples: unprocessed, 1.5, 1.0, or 0.5 mm. After drying, samples were placed into a Ro-Tap particle separation machine for 10 minutes until the whole sample was separated. Whole samples, as well ...


Evaluation Of Weather Information From On-Farm And Meteorological Stations To Assess Heat Stress In Dairy Cows In Southwest Kansas, A. Scanavez, L. Rocha, B. E. Voelz, L. Hulbert, L. Mendonca Jan 2016

Evaluation Of Weather Information From On-Farm And Meteorological Stations To Assess Heat Stress In Dairy Cows In Southwest Kansas, A. Scanavez, L. Rocha, B. E. Voelz, L. Hulbert, L. Mendonca

Kansas Agricultural Experiment Station Research Reports

Heat stress represents a challenge for the dairy industry. In order for producers to implement appropriate management practices, it is crucial for researchers to assess the extent of heat stress to which cows are exposed during the summer. Temperaturehumidity index (THI) may be used to determine the severity of heat stress that cows are exposed to during the summer. The objective of this study was to evaluate climate conditions by calculating THI using information from: 1) an official meteorological station, 2) loggers at the pen-level, and 3) loggers at the cow-level from a commercial dairy located in southwest Kansas. Temperature-humidity ...


Benchmarking Reproductive Efficiency And Transition Cow Health Of Kansas Dairy Herds, A. Scanavez, B. E. Voelz, L. Mendonca Jan 2016

Benchmarking Reproductive Efficiency And Transition Cow Health Of Kansas Dairy Herds, A. Scanavez, B. E. Voelz, L. Mendonca

Kansas Agricultural Experiment Station Research Reports

Comparing key performance indicators across dairy farms may provide insightful information to dairy producers. Differences in management philosophies, facilities, and locations of dairy farms may influence overall performance of dairy operations. An ongoing extension program aims to benchmark reproductive performance and transition cow health of dairy farms located in Kansas and adjacent states. In this report, we compiled data from 2013 to 2015 of herds enrolled in the program and divided the data in warm and cool seasons to evaluate the impact of heat stress on key performance indicators. Annual pregnancy risk and warm to cool ratio of pregnancy risk ...
