TI  - Determination of the Eff ects of Silage Type, Silage Consumption, Birth
Type and Birth Weight on Fattening Final Live Weight in Kıvırcık Lambs
with MARS and Bagging MARS Algorithms
AB  - Th is study was carried out to determine the eff ect of silage type, silage consumption, birth type (single or twin) and birth weight
on live weight at the end of fattening in Kıvırcık lambs. In the experiment, 40 male Kıvırcık lambs aged 2.5-3 months were used and the
animals were fattened for 56 days. During the fattening period, the lambs fed with 5 diff erent types of silage (100% sunfl ower silage, 75%
sunfl ower + 25% corn silage, 50% sunfl ower + 50% corn silage, 25% sunfl ower + 75% corn silage, 100% corn silage) pure and mixed in
diff erent proportions and concentrate feed. Data on fattening results were analyzed with MARS and Bagging MARS algorithms. Th e main
objective of this research is to predict fattening final live weight (FFLW) of lambs using Multivariate Adaptive Regression Splines (MARS)
and Bagging MARS algorithms as a nonparametric regression technique. Live weight value was modeled based on factors such as birth
type, birth weight, silage type and silage consumption. Correlation coefficient (r), determination coefficient (R2), Adjust R2, Root-meansquare
error (RMSE), standard deviation ratio (SD ratio), mean absolute percentage error (MAPE), mean absolute deviation (MAD), and
Akaike Information Criteria (AIC) values of MARS algorithm predicting live weight were as follows: 0.9986, 0.997, 0.977, 0.142, 0.052,
0.2389, 0.086 and -88 respectively. Like statistics for Bagging MARS algorithm were 0.754, 0.556, 0.453, 1.8, 0.666, 3.96, 1.47 and 115
respectively. It was observed that MARS and Bagging MARS algorithms have revealed correct results according to goodness of fit statistics.
In this study it has been determined that the MARS algorithm gives better results in live weight modeling.
