Korelasi fenotip antara ukuran bagian tubuh dengan bobot badan dari silangan ayam pedaging, kate dan lokal sabu pada umur dua belas minggu

  The purpose of this research was to know the relationship between the the weight and body measurements at age of 12 weeks  of crossbreds of three chicken types that were broiler, kate and Sabu chicken. The relationship of body weight with the body measurements  was used as a consideration for selecting the body weight.  The research  material  was 30 tails of  crossbreds  with genotype composition was ½ broiler 1/4  Kate ¼ Sabu chicken.  The method of research was experiment and directly weighting and measuring of the body measuremens. All  chickens  were given freely the  same  food  and waters. The observed parameters were body  weight, backbone  length, chest circumference, shank circumference and wing span.  Data   was analised using the correlation analysis.  Research results  obtained  the koefisien of correlation between  chest circumference, backbone length,  shank length  and wing span  with body weight were 0.62; 0.32; 031 and 0.20.  Correlations between body weight  and  body measurements  of chicken crossbreds   with genotype composision ½ broiler  ¼ Kate ¼ Sabu   were positip.
