PENGARUH SEX TERHADAP TAMPILAN SIFAT PRODUKSI SAAT LAHIR ANAK BABI DARI INDUK PERANAKAN LANDRACE (Influences of sex on production performace at birth age of pigs from landrace crossbred sows)

Abstract

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.
