Abstract

Abstract. The aim of the research was to evaluate the efficacy of protection method of rumen protected fat-protein supplements. In vitro digestibility test was carried out to examine nutrients digestibility of different supplement formula based on the sources of protein and oil. The research used two sources of fat namely crude palm oil (CPO) and fish oil (FO) and three sources of protein namely milk skim, soy flour, and soybean meal. Thus there were 6 combinations that subjected in the in vitro digestibility test. The observed variables were the digestibility of dry matter (DM), organic matter (OM), crude fat (CF), and crude protein (CP). Results indicated that the method for protecting protein and fat was effective. This was showed by low nutrients digestibility in the rumen and high nutrients digestibility in the post rumen. In conclusion the combination between skim milk and CPO gave the best results among the other supplement formula.Keywords: rumen protected nutrient, fat-protein supplement, rumen digestibility, in vitroAnimal Production 14(1):1-5, January 2012

Abstract

This research was aimed to examine the effect of difference fibrous feeds on feed intake and digestibility in swamps buffaloes compared to ongoles cattles. Twelve ongole and twelve buffaloes were used in in vivo digestibility. Ten feeds were used in this experiment, namely Peanut Haulm (PH), King Grass (KG), Corn stover (CS), Elephan Grass (EG), Rice Straw (RS), Soja Straw (SS), Corn Straw (CST), Glyricidea (Gli), and Caliandra (Cal).  The observed variabels were intake of DM, OM, CP, NDF. The results showed that DM and OM intakes were significantly influenced by feed stuffs origin ranged from the lowest (Gli) of 29.55 g DMI/kg0.75 to the highest (CS) of 94.88 g/kg0.75. OM intake of buffaloes was higher than that of ongole cattle supported by organic matter (OM) digestibility data (61.51 vs 59.51).  The digestibility of nutrient was significantly influenced by feed stuffs origin. OM digestibility of SS were lowest while the highest were CST of 54.56 and 71.66% respectively. Digestibility of CP  was also significantly  influenced by feed stuffs origin. The lowest Digestible Crude Protein  was CST and the highest was PH of 44.10 and 67.99% respectively. The digestibility of NDF and ADF were significantly influenced by feed stuffs. The lowest NDF and ADF digestibilities were Cal of 40.84 and 33.19% and the highest digestibility of NDF and ADF were CST of 68.53 and 63.57%.  It can be concluded that there were an important variation of feed compositions and digestibility of fibrous feeds. Buffalo were better than cattle on capacity of ingestion and utilization of fibrous feed.

Abstract

An experiment was conducted to determine the effect of undegraded protein and energy level on intake and digestibility of nutrient and glucose and urea blood content in dairy cows. The benefit of the research was to inform about the utilization of undegraded protein and energy level to optimize nutrient utilization in dairy cattle. The experiment was conducted in 4 month in the Department of Animal Nutrition and Feed Science, Faculty of Animal Science Gadjah Mada University. The experiment used 4 female rumen fistulated dry cows (Friesian Holstein Crossbreed) of 3.0-3.5 years old and 350–400 kg body weight. The treatments of this experiment were T1: 20% of undegraded protein (UDP) and 70% energy from requirement; T2: 20% undegraded protein and 120% energy from requirement; T3: 30% undegraded protein and 70% energy from requirement; and T4: 30% undegraded protein and 120% energy from requirement with Latin square design.  Variables observed were intake and digestibility of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), Acid detergent fiber (ADF),  and glucose and urea blood content. Collected data were analyzed by analysis of variances, and further differences were tested by orthogonal contrast. Results of the research showed that the level of UDP in the rations did not affect DM, OM, CP intake, rumen degradable protein (RDP), NDF and ADF; however level of energy had significant affect on DM, OM, CP,  RDP and ADF intake. The level of UDP resulted in non significant difference in DM; but significantly different on CP digestibility. Digestibility of DM and OM were significantly influenced by the level of energy, but it did not influence NDF and ADF digestibility. Cattle treated with the high energy rations had higher blood glucose concentration than cattle treated with the low energy rations. Blood urea in cattle fed low UDP rations was higher than cattle fed high UDP rations. (Animal Production 10(2): 96-101 (2008) Key Words: Undegraded protein, nitrogen, energy, blood metabolite
