Abstract

The research conducted to estimate the heritability value and genetic correlation of growth traits of crossbred F (indigenous hens X Bangkok cocks) were done over 28 weeks. Five groups of pen mating poultry were used in which one cock and five hens were used for each group. Therefore, there were 5 cocks and 25 hens as parent stock and 152 crossbred F. Variables of the research were body weight of DOC, body weight of 4th weeks and 8th weeks. The variations of body weight by sex were eliminated by transforming the female body weight to male body weight using correction factor. Estimation of heritability value (h²) used an anova of nested design method. Estimation of genetics correlation (rG) used an  ancova of nested design. Results of heritability estimates and genetic correlation showed that the h² was 0.13 for Doc body weight, 0. 67 for 4th weeks, and 0,59 8th weeks. The rG was 0.89 for DOC to 4th week body weight, and 0.55 for DOC to 8th week body weight

Abstract

The study to identify the effects of different concentrate supplementation on the reproductive performance of the local rabbits fed with basal ration (i.e.: sweet potato forages – ad libitum) was carried out in Jono Oge village - Biromaru, Donggala–Central Sulawesi. The study used 12 multifarious does which were allocated to four treatments using a Randomized Block design (RBD).  The treatments were as follows: does fed with basal ration (R0); does fed with basal ration supplemented with concentrate at 1% (R1), 2% (R2), and 3% (R3) of body weights.  Litter sizes, weights at birth   and weaning of kids were then recorded.  Results showed that concentrate supplementation for the  local rabbits fed with basal ration of sweet potato forages did not significantly affect the litter size and  birth-weight of kids but the treatments did significantly affect their weaning-weights (21 day old).

Abstract

Sulawesi is an island that has high biodiversity. However, utilization of natural resources has been harming habitat of animals. The destructions of their habitat cause some animals become extinct from earth. Tarsius wallacei is one of the primate species from Tarsidae family and is an endemic species of Central Sulawesi region.  This research was done because the status of Tarsius becomes an endangered species. The purpose of this research was to estimate the population of T. wallacei at Lebanu village. This research was conducted during 3 months using Point Count method. The result of this research showed that populations of T. wallacei at Lebanu village are 11 groups and their densities are 0.19 groups/ha.

Abstract

Tarsius wallacei is an endemic mammal of Sulawesi published by Merker, et al on 2010. Even though the distributions, vocalizations and morphometric have been studied well, the ecological aspect especially type of feed was not studied whereas the diet information is an important data for conservation of this endemic species. The objective of the study was collect the variety of tarsius’s prey in the wild. A collection of samples has been conducted from February to October 2015 using sweep net, light trap, and hand capture methods. The results of prey collection show that Tarsius wallacei feed on insects. Thirteenspecies were found as a prey of Tarsius wallacei which consists of 10 order, i.e. Orthoptera, Blattodea, Coleoptera, Araneae, Lepidoptera, Hemiptera, Odonata, Isoptera, Hymenoptera and Homoptera. Proximate analysis of the three orders that belong to the group Insecta indicated the Tarsius wallacei probably consume mainly on Orthoptera with the highest protein content, 69.32%, followed by Lepidoptera (66.51%), and Coleoptera (41,98%)

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.
