Abstract

The objective of the research was to determine the best hatching technique of maleo eggs from various measures such as as ex-situ, incubation time and hatch capacity of maleo bird using incubator. Thirty eggs were collected from the Lore Lindu National Park of Palu, Province of central Sulawesi according to an accidental sampling. The results showed that the mean weight of eggs from the National Lore Lindu Park was 208.80 ± 12.30 g, egg length was 102.85 ± 0.034 mm while egg width was 60.66 ± 0.02 mm.  The mean of incubator temperature of was 34.061 ± 0.19ºC with relative humidity of 70.87 ± 1.43 %. The percent of hatching eggs for incubation time of 53-55 days was 23.81 %, for that of 56-58 days was 23.81 %, for that of 59-61 days was 42.85 % and for that of 62-64 days was 9.53 %.  Thus, the average time for the eggs to hatch was 58.47 ± 2.88 days at the hatched rate of 70%. Based on such figures above, it can be concluded that the hatching technique using incubator could become the conservation strategy for maleo bird in Sulawesi particularly in Central Sulawesi Province

Abstract

The objective of this research was to identify the dynamic population of beef cattle at North Pamona of Poso regency. This research was an analytical descriptive study conducted using survey method on 572 respondents taken using a purposive sampling method from all villages at         North Pamona. The result showed that the composition of beef cattle were 533 (34.88%) bull and 995 (65.12%) cows. The total number of bull calves, bullock and bull were 93, 100 and 340, respectively, while the heifer calves, heifers and cows were 135, 130 and 738 respectively.          The birth rate was 30.89% or 14.83% of the total population whereas the motility rate was 2.7% so that the natural increase was 12.13%.  Key words: Beef cattle, population and reproductivity.
