Reproducibility, Repeatability, and Degree of Expertise Required to Assess Body Condition Score in Beef Cattle1

Autor: R.P. Wettemann, J.A. Vizcarra

Publikováno v: The Professional Animal Scientist. 12:28-31

Ninety-eight Hereford × Angus beef cows were used to determine reproducibility (the correlation between an animal’s score by one technician and its score by a different technician), repeatability (the correlation between an animal’s score on one
