This study was conducted to the suckling behavior on the growth of Cheju native black piglet during the suckling period. The data for this study were obtained from 24 heads of Cheju native black piglet(fema1e 15 and male 9). The traits studied were composition of milk, body weight and comformation of piglets. The results obtained in this study are summaried as follows; 1. The composition of clostrum were 80.11 % water, 19.89 % solids, 7.46 fat, 8.95 % protein, 3.29 % lactose, 0.29% minerals, pH value was 6.42.

There dfference between male and female ivas significant(p<O.05). 4. The body length in female and male piglets was 18.69 and 19.79 cm at birth, 32.22 and 33.86 cm after 3 wk, 42.59 and 43.07 cm after 6 wk, respectively. There dfference betiveen male and female ignificant(p<0.05). The chest girth in female and male piglets was 22.28 and 23.43 cm at birth, 38.31 and 39.6.1 cm after 3 wk. 37.81 and 50.00 cm after 6 wk, respectively. There dfference between male and female was significant(p<0.05). 5. The chest width in female and male was 513 and 5.36 cm at birth, 8.93 and 10.07 cm after 3 wk, 12.09 and 13.00 cm after 6 wk, respectively. There dfference between male and female was not significant(p<0.05). The pine width in female and male was 2.03 and 2.71 cm at birth, 3.97 and 4.93 cm after 3 wk, 5.88 and 6.57 cm after 6 wk, respectively. There dfference between male and female was significant(p<0.05). 6. The shin circumference in female and male was 5.03 and 5.64 cm at birth, 7.34 and 7.79 cm after 3 wk, 8.86 and 9.36 cm after 6 wk, respectively. There difference between male and female was significant(p<0.05). The head length in female and male was 6.84 and 7.43 cm at birth, 9.87 and 10.21 cm after 3 wk, 12.41 and 13.00 cm after 6 wk, respectively. There dfference between male and female was not significant(p<0.05). The head width in female and male was 4.16 and 4.57 cm at birth, 5.97 and 6.14 cm after 3 wk, 7.09 and 7.71 cm after 6 wk, respectively. There dfference between male and female was not significant(p<0.05). 7. The ear length in female and male was 5.56 and 5.86 cm at birth, 8.47 and 9.14 after 3 wk, 10.78 and 11.50 cm after 6 wk, respectively. There dfference between male and female was significant(p<0.05). The ear width in female and male was 4.19 and 4.64 cm at birth, 6.03 and 6.43 cm after 3 wk, 8.09 and 8.64 cm after 6 wk, respectively. There dfference between male and female was significant(p<0.05). The tail length in female and male was 7.25 and 7.29cm at birth, 10.38 and 10.50 cm after 3 wk, 13.88 and 14.43 cm after 6 wk, respectively.

This study was conducted to the suckling behavior on the growth of Cheju native black piglet during the suckling period. The data for this study were obtained from 24 heads of Cheju native black piglet(female 15 and male 9). The traits studied were composition of milk and suckling behaviour of piglets. The results obtained in this study are summaried as follows; 1. The suckling duration of piglets were 126.4 min. after 1 wk, 93.2 min. after 3 wk, 72.4 min. after 6 wk, respectively. There were significant difference between weeks(p<0.05). The suckling interval of piglets were 32.7 min. after 1 wk, 44.6 min. after 3 wk, 47.3 min. after 6 wk, respectively. There were significant difference between weeks(p<O.O5). The suckling frequency of piglets were 19.6 times after 1 wk, 14.5 times after 3 wk, 13.9 times after 6 wk, respectively. There were significant difference between weeks(p<O.O5). 2. The resting duration of piglets were 963 min. after 1 wk, 1023 min. after 3 wk, 966 min. after 6 wk, respectively. There were not significant difference between weeks(p<0.05). The playing duration of piglets were wk, 191 min. after 3 wk, 215 min. after 6 wk, respectively. There were not were 20 min. after 3 wk, 48 min. after 5wk, 62 min. after 6 wk, respectively There were significant difference between weeks(p<0.05). 3. The urination frequent). of piglets were 13.9 times after 1 ivk, 8.0 times after 3 wk, 1.7 times after 6 wk, respectively. There were significant dfference between weeks(p(O.01). The defecation frequency of piglets were 0.9 times after 1 wk, 1.8 times after 3 wk, 3.4 times after 6 wk, respectively. There tvere significant dfference between weeks(p<0.0l). The drinking water frequency of piglets were 3.3 times after 1wk, 48 times after 3 wk, 10.7 times after 6 wk. respectively. There were significant dfference between weeks(p<0.0l). 4. Protein content of native sows milk was considerablely higher than that of the introduced sows milk but the fat and sugar content in the milk were lower than those of introduced sows milk. The results of suckling behaviour and litter performance study of Cheju native piglets may contribute to the effective breeding and feedmg management of Cheju native black swine production.
