Abstract

This research was undertaken to evaluate energy utilization and blood metabolites status of male Indonesian local sheep involving nutrient balances and using urea space techniques for measurement body composition. Factorial randomized completely design was used in this study using 16 growing male local sheep. Factor A was breed which consisted of 8 Garut sheep (av.BW 14.90 kg) and 8 Jonggol sheep (av.BW 13.60 kg). Factor B was different ration which received of diet containing Indigoferasp. and sproutbean waste. The ration offered were pellets containing CP around 16% and energy 15.6 MJ GE kg-1. Energy balance and blood metabolites studies were conducted during three-months trial. Intake, digestibility, urinary and metabolism variables were measured based on total collection method. Methane energy was measured by rusitec technique and methane gas production multiplied by calory equivalent value of methane. Energy retention (RE) was measured by urea space technique. Heat production was calculated from ME-RE. Plasma glucose, cholesterol and urea-N were measured by using spectrophotometry. Results showed that there were significant differences of energy intakes, digestibilities and metabolism among the rations. Animals fed with sproutbean waste ration has higher energy utilization compared to those fed Indigofera sp ration. There were no significant different for all blood metabolite variables among breed and its interaction between combination treatments. It is concluded that sproutbean waste in local sheep ration has higher energy utilization and daily gain than Indigofera sp. Keywords: Indigofera sp., local sheep, rusitec technique, sproutbean, urea space

Abstract

There are various studies on AGP substitute feed additives that provide many options for solutions related to the problem of maintaining gut health. Therefore, it is necessary for a fundamental evaluation of the use of some feed additives on the response of livestock. The purpose of this engineering practice is to find best solution for growth promoter antibiotics (AGP) alternatives that can be effectively used in laying hens Farm. Trials of several probiotic and organic acid product supplementation were carried out on 21,000 laying hens of the HyLine Brown strain aged 50 weeks for 1 month. Tested products were protected probiotic powder (OGC), liquid probiotics (PBL) and liquid organic acids (APK), these products were evaluated based on production egg quality and cost feasibility studies. Data on egg production and egg quality were analyzed using ANOVA and then actually compared between treatments with Tukey's test (p<0.05) and also compared based on production standards from producers/breeders. The trial results showed that the use of liquid probiotics (PBL) resulted in the highest egg production and egg weight, organic acid products (APK) resulted in higher distribution of large eggs and more efficient feed conversion, the use of protected probiotic powder (OGC) resulted in highest haugh unit. The economic feasibility study shows that organic acid products (APK) produce the highest return on investment value. The concluded showed that organic acid product (APK) will be effectively used in laying hens Farm. Key words: egg quality, laying hen, organic acid, probiotic
