Analisis Regresi dan Korelasi antara Seleksi Bobot Badan Fase Starter Terhadap Produksi Ayam Ras Petelur Strain Isa brown

Abstract

ERICKO UNUTIO, 2014. "Regression and Correlation Analysis between Starter Body Weight Selection against Layer Production Strain Isa brown". Guided by HAMDAN and TRI HESTI WAHYUNI. This study aims to determine the relationship between Starter body weight Selection (1 week) on egg production, first laying age, and first egg weight. This study was held in CV. PTB Poultry Farm in the village of Sei Limbat, District Selesai, Langkat Regency in April to August 2014. This study used 200 DOC with initial weight of 39.33+2,63g. Selection is done by weighing 200 Starter (1 week) with the requirement of 10 highest weight from 200 Starter (1 week) that has calculated with the mean and standard deviation as a selection criterion with the weight of 78.5+1,43g as many as 100 selected and 100 non-selected for comparison. The results showed that the selection of starter (1 week) body weight to first egg weight has the highest value in the correlation value (r = 0.722) and the regression value (R=0.722). While the non-selection of starter (1 week) body weight to first egg weight has the highest value on correlation value (r = -0.357) and the regression value (R2=0.357). The conclusion of this study is if the starter (1 week) body weight in selected chicken increases, the first egg weight will increase by 72%. Meanwhile, if the starter (1 week) body weight in non-selected chicken increased, the first egg weight will decrease by 35.7%.
