Abstract

The aims of this research  were to  estimate   repitability  coefficients of production  at birth  and  weaning characters  and to determine the average and standard deviation  of landrace  crossbreed sows. This research  was carried out in two breeding farms namely the Instalation of Pig Breeding, village of Tarus, Kupang Regency and the Manise Pig Farm, Village of Oetete, Kupang City, East  Nusa  Tenggara.   Materials used  15heads  landrace  crossbreed  sows ( 15  heads ) which born and weaned piglets  during the study periode.  The number of piglets for the first parity was 151heads and for the second parity was  162heads. All  sows  was  mated by artivicial insemination  with  boars of  landrace  crossbreed.   Variables were  liter size, weaning rate, birth weight, weaning  weight and weaning  rate.  Results  showed that landrace  crossbreed sows had the  average and  deviation standard for  the first and second liter size were 10.00±1.50heads  and  10.73±2.40heads, respectively;  for the first and second  birth weight were 1.37±0.23kg and 1.68±0.34kg, respectively;  for the first and second weaning  weight were  6.42±0.38kg  and  6.72±0.51kg, respectively  and for the first and second weaning rate were 8.33±1.28heads and  8.68±1.43 heads; respectively.  The average of litter size, birth weight, weaning weight and weaning rate between the first and second  parity  was no difference (P > 0,05). The  value of  repeatabitily for  characters  of  liter size, birth weight, weaning weight  and  weaning  rate   were  0.32; 0.47;  0.49 and 0,42; respectively.   In  conclusion,  the   repeatabily value   of litter  size,  birth weight, weaning  weight and weaning rate from landrace  crossbred sows were  medium value  and the performance of  those characters between  the first  and  second parity were  no difference.
