ABSTRACT This study aimed to analyze the effect of grasslands, meadows, and pastures on the efficiency of dairy farming and cattle farming in Türkiye and European Union countries. The primary data for this study included information on the production of raw milk and cattle meat, nitrogen content in treated manure, dairy cow populations, livestock standard units (LSUs), and the extent of grasslands, meadows, and pastures in both European Union countries and Türkiye. In the study, two distinct models were developed: […]

ABSTRACT This study aimed to assess the physical performance of Pantaneiro horses with and without equine infectious anemia (EIA) under functional conditions of cattle management. The horses were subjected to a performance test and split into two groups according to a completely randomized design: animals were chosen from populations testing positive and negative for EIA. Performance was measured as a function of a data envelopment analysis (DEA) model considering four outputs and one unitary input. The output measures were the […]

This study estimates the technical efficiency of goat rearing in the province of Isparta in Turkey using Data Envelopment Analysis (DEA). The data used were collected from 92 goat farmers using the stratified sampling method by means of a questionnaire. The technical efficiency of the goat farming varied widely between 0.13 and 1.00. The mean efficiency of 92 goat farms was calculated to be 0.44 and 0.66 for constant and variable returns to scale assumptions, respectively. The greatest slacks were […]
