Estimation of productive efficiency in ewes from the natural grasslands of Southern Brazil: A pilot approach

<p>*The dataset used was provided by a sheep farm that collected information of an entire production cycle during the year 2024 to achieve the internal selection of matrices. The raw data were obtained from 231 ewes with 18 variables. However, after editing, 102 ewes and 11 variables were considered, excluding observations with missing values and remaining with variables of ewe dams (identification, age, breed, and four BCS measurements) and the progeny (sex, birth type, breed, and weaning weight). The units of measurement for the variables were: identification as alphanumeric; age as a numeric value, expressed in years; breed as alphanumeric; BCS measurements as qualitative ordinal numeric values, ranging from 1 (very thin) to 5 (very fat); sex, with 1 for male and 2 for female; birth type, with 1 for single and 2 for twins; and weaning weight, expressed in kg.
