Abstract

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.
