Aim: In this study, the data obtained to describe the body characteristics of the Hair Goat ,were utilized in the businesses that were registered with Karaman Province Breeding Sheep and Goat Breeders Association. Body measurement of 130 goats, 2-7 years old and 50 billy goats, 2-4 years old, selected by simple random sampling method for total 900. The main motivation of the study was to determine the relationship between body weight and some body measurements with nonlinear models in hair goats in Karaman region.

Materials and Methods: In the study, we estimated the live weight with nonlinear models. Nonlinear univariate regression models were used.

Results: When the results of the study were evaluated, statistically significant results were obtained by using Quadratic or Cubic methods from nonlinear univariate models.

Conclusion: Researchers may choose the multivariate regression method occurs when the appropriate terms and conditions, but with time constraints and chest girth quadratic or cubic univariate methods impractical for situations be offered an estimate using the variable.
