Abstract

Palm sludge is a by-product of the palm oil processing that is quite numerous and still contains nutrients that can be utilized as an alternative feed ingredient for poultry. However, high crude fiber content resulted in the utilization of alternative feed ingredients for poultry is limited. The fermentation process can increase nutritive value of the palm sludge. This research aimed to study the use effect of the fermented palm sludge (FPS)in the ration on the growth performance of broiler. The research has been conducted in the animal teaching farm of theAnimal Husbandry Faculty starting from October 9th to November 13th, 2013 using 80 DOCs (day old chickens) produced by PT. Satwa Utama Raya, Makassar. Those DOCswere raised in the 20 cages that each has a size of 60x60x90 cm. Each cage was placed by buckets of ration and drinking water. A complete randomizeddesign was used in this research with 5 treatments and 4 replications.  The treatments were R0 (ration without FPS), R1 (ration with 2.5% FPS), R2 (ration with 5.0% FPS), R3 (ration with 7.5% FPS), R4 (ration with 10.0% FPS). The research parameters were feed consumption, body weight gain, and feed conversion.The result showed that treatments affected non-significantly (P>0.05) on the three observed variables. It was concluded that the fermented palm sludge still can be used up to 10% in the broiler’s ration.Key words: broiler, fermented palm sludge, growth performance

Abstract

            Vegetation that grows naturally in certain areas is a reflection of the interaction of various environmental factors and may change at any time. Under oil palm trees, there are several types of vegetation that have the potential to be used as animal feed, but it has not been identified yet. This study aimed to examine the types of vegetation that grows under the oil palm trees, and could potentially be used for animal feed. Observations were conducted on 3 groups of oil palm plantations aged above 10 years which belong to:  i.e. smallholder oil palm, private estates, and state estates company. In each group, it was taken 8 plots so there were 24 plots in total. Parameters observed were the types of plants (i.e. grass, legume, and weed), plant nutrient content (determined by using proximate analysis), microclimate and soil organic matter content (C and N), and soil pH. Collected data were analyzed descriptively, and were followed by a t test.   Results showed that herbages grow in palm-oil plantation in the Ness village are more various than that of in the Arang-arang village.  Ottocloa nodosa and Eulisine indica are two grasses species that might be potential in the Arang-arang village which has a pity soil type, while Leersia hexandra, Paspalum sp., and Ottocloa nodosa are species of grasses which grow in the Ness village which has a yellow-red podsolic soil type.  The existence of Melastoma malabathricum in the Arang-arang village should be considered as this species contains poisonous substances.  Calopogonium sp. and Mimosa sp. are spesies of legumes that could be developed in palm-oil pasture to improve N content of herbages.  Nitrogen or mineral fertilization might be needed to improve soil fertility of different soil types.Key words: oil palm, vegetation, weeds, animal feed, soil

Abstract

A pot trial aimed comparing several aspects of agronomical atributes of two types of Panicum has been carried out from August to September 2018 in the greenhouse of Tadulako University, Palu. A completely randomized design (CRD) of two treatments which were repeated 10 times was used in this study. The variables observed included plant height, number of tillers, length of leaf-sheath, length of leaf-blade, leaf width, and dry matter production. The data collected was analyzed for variance using the SX program, with followed-up by the least significance difference test (P=0.05) for variables that were significantly affected by treatment. The results showed that Panicum sarmentosum grass has a similarity to Panicum maximum in terms of number of tillers, leaf-sheath length, leaf width, and plant height (P>0.05), except for leaf-blade length, and dry matter production (P<0.05).
