ABSTRACT   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.

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.

This  aim of the research  was  to  know  production performances at  birth  age of  piglets of  landrace sow crossbreds. The  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.  There were 15 heads of landrace crossbreed sows.  The method used wasa survey and samples were  collected purposively that there were all of the landrace sow crossbreds.   The variables  were litter size, body weights, girth size, and  body length. Data were differentiated between males and  females. The data obtained was  analysed  using the t test (t-test).  The results showed that males had the average  of litter size,  body  weight, girth size  and body length were 5.03±1.81 head; 1.48±0.58 kg/head;  24.82±3.29  cm and  22.21±4.18 cm,  respectively  while females had  the average  of  liter size,  body  weight, girth size  and body length were 4.80±1.49 head;  1.45±0.49 kg/head;  24.51±3.17cm  and  21.78±4.75 cm,  respectively.  Statistical  analysis showed that there  was  no  difference  (P>0.05) between  males  and females from  all  observation variables. Performances of piglets  from  ;andrace  sow crossbreds for  male and female characters such  as  litter size, birth weight, girth size  and body length were  relatively similar.

This  research aim was  to  know  reproduction performances at  birth  and  weaning age of  the sows which were  mated  with  Duroc  and  Landrace  studs. The  research  was  carried  out in  two breeding farms namely the Instalation of  Pig  Breeding, the  village  of  Tarus, Kupang  Regency  and  the Manise Pig Farm, Village of Oetete, Kupang City.  There were two breeds of studs namely breed of Landrace and Duroc which each stud was  mated to  15  breeding pigs.  The method used in this research  was a survey and the samples were  collected purposively.  Data collection  were obtained when the piglets were born and weaned.  The variables  were the litter size  and  body  weight  at birth age and the  liter size and body  weight  at  weaning  age. The data obtained was  analysed  using the t test (t-test).  The results showed that the characters  of  birth litersize,birth  body  weight, weaning litter size  and  weaning    weight   for Duroc stud  were  10.60±2.41 head,  1.95±0.18 kg/head; 10.00±2.02 head and  5.98±0.65kg/head,  respectively and  those  charackters  for  Landarace  stud were  9.06±2.09head, 1.98 ±0.22 kg/head;  8.93± 2.23 head and  6.20±0.28 kg/head,  respectively.  Results of  statistical analysed showed that  Duroc  and  Landrace  studs did not effect significantly  (P>0.5)  for  those  charackters.  Reproduction performances of sows  that were  mated  with  Duroc  and  Landrace studs for  characters of birth liter size, birth weight,  weaning liter size  and  weaning  weight were  relatively similar.
