Abstract

The knowledge of probiotic spread widely, mainly after having been found some probiotics that can be used by animal. The result of research on the usage of some types of probiotics in rations of chicken give different influence on chicken productivity. Using probiotic starbio 0.25% in ration could increase the body weight of broiler up to 6 weeks of age and could increase the consumption of crude fibre up to 6% in the ration. Using probiotic starbio 0.25% in ration of layer could increase 19-26% eggs products and reduce feed conversion and water content in faeces and give additional income for the farmers as 44 up to 48%. Culture yeast as much as 0.2−0.3% is effective to add in rations of broiler 0−4 weeks of age. Lactobacillus acidophilus 2% and 4% in rations of layer may increase 5−11% of egg products and reduce feed conversion. It can be concluded that using probiotic in rations may increase the productivity of broiler, layer and native chickens.   Key words: Probiotic, chicken diets, productivity of chicken

Abstract

The optimal productivity of native chicken could be reached if reared on thermoneutral zone, a comfortable environment temperature. The comfortable environment temperature for the native chicken is still unknown, but it is predicted on around 18 to 25 °C. The native chicken placed on high temperature (25-31 °C) shows low productivity, including lower product and the weight of eggs, and also low growth rate. The decrease of egg number could reach 25% compared with those placed on comfortable environment temperature. The weight of 8 week-age ofnative chicken are also different i.e 257 g on high temperature, while on comfortable temperature could reach 427 g. This productivity decreased is mainly caused by the decreased of feed consumption, and also by the change of physiological condition of the chicken. The efforts to increase the native chicken production on high environment temperature are through selecting and crossing, manipulating environmental temperature, improving rearing management, and manipulating feedstuff and feed management. Manipulating feedstuff is the cheapest method, easy to do for increasing the amount of nutrient consumption. The method is by adding vitamine C, phosphor or giving sodium bycarbonate in the rations. The amount of vitamine C addition is 200-600 mg/kg ration on chicken producing eggs and 100-200 mg/kg ration to improve the chicken growth.

Abstract

An integrated system between cattle and oil palm plantation has a great potency for development of bioindustry, either in the form of animal feed or organic fertilizer bioindustry. Bioindustry of cattle feed is developed from biomass of plantations, such as stem and leaves of palm, palm kernel and solid. Bioindustry of organic fertilizer is developed from cattle manure. The targets of development of bioindustry are palm plantations in Sumatera and Kalimantan regions, covering 9.25 million hectares. It is estimated to be able to produce biomass quantity as much as 54.60 million tons per year which can be used as fodder for 12.13 million animal unit (AU) of beef cattle, whereas currently there are only 3.06 million AU cattle in Sumatera and Kalimantan, so the opportunities for the addition of cattle in both islands are 9.07 million AU. The existing beef cattle population of 3.06 million AU has the potency to produce 6.1 million tons of organic fertilizer can be used to fertilize 3.0 million hectares, therefore the rest of 6.25 million hectares remain unfertilised. The prospect of bioindustries on integration system of cattle with oil palm plantations in Sumatera and Kalimantan is very potential to meet the needs of organic fertilizer for plants and to utilize oil palm biomass for cattle feed. Key words: Bioindustry, biomass of oil palm plantation, cattle manure
