Effect of Difference Tropical Fibrous Feeds on Feed Intake and Digestibility in Swamps Buffaloes Compared to Ongole Cattle

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. (Animal Production 12(2): 86-90 (2010

The result showed that differences (

EFFECT OF PROTEIN UNDEGRADED SUPPLEMENTATION ON PRODUCTION AND COMPOSITION OF MILK IN DAIRY COWS

This research was aimed to examine the effect of undegraded protein supplementation on nutrients intake, production and milk composition in dairy cows. The purpose of this research was to provide information on the undegraded protein supplementation to increase milk production and composition in dairy cows. The research was conducted for 3 months in Boyolali-Central Java. The study used 20 lactation cows (<3 months of lactation), aged 3 to 3.5 years with body weight from 350 to 400 kg. The cows were then randomly divided into 2 groups of ten based on their body weight, milk production, lactation period and age. The first group (control) and the second group (treated), both were fed diet based on NRC (1987). The second group was added undegraded protein (UDP) of 30 g/l milk that mixed by concentrate. The observed variables were dry matter intake (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), milk production and milk composition including fat, protein and solid non fat (SNF). Data obtained were examined by t-test. The results showed that intake of DM, OM, and the NDF of treated and control groups were not different (9.57; 8.49; 4.98 vs 9.44; 8.38; 5.40 kg/cow/d, respectively); however, protein intake of treated group was higher (P<0.01) than that of the control group (1097 vs. 1210g/cow/d). Milk production of cows receiving UDP supplementation tended to be higher than that in the control group (+ 1:45 kg/cow/d). Although they tended to be lower in fat (4.13 vs. 3.88%), protein (2.45 vs. 2.27%) and SNF (7.26 vs. 6.94%), but protein and fat production were higher for cows receiving UDP supplementation (366 each; 214 vs. 330; 196g/cow/d). It can be concluded that UDP supplementation increased milk, fat production and milk protein but it tended to reduce the level of fat, protein and SNF milk.

Examination of the Ratios of Inoculums of Buffalo Faeces and Buffer Solution on the In Vtro Fibrous Feed Digestibility

An investigation has been conducted to examine the ratios of inoculums made of buffalo faeces def-ecated and buffer (artificial saliva) on the analysis of in-vitro digestibility of dry matter and organic matter of rice straw, corn forage, elephant grass, pangola grass, and peanut straw, respectively. The ratios between feces to buffer provided were 1:4, 1:2, 2:3, 2:1, and 1:5. Rumen inoculums were obtained from two mature female rumen-fistulated buffaloes maintaining with mixed ration of 70% elephant grass and 30% concen-trates fed ad libitum (3% dry matter requirements to body weight). Rumen fluid was collected before morning feeding. After 10-days acclimatization, the specified data were collected. The results showed that inoculums ratios of 1 :2 were significantly affected the in-vitro digestibility of forages tested. The efficacity of this test was 95%. Therefore, faeces and buffer ratios were potential to be used for inoculums for in-vitro feed digestibility assay during 48 hours incubation period.

Effect of Undegraded Protein and Energy Level on Intake and Digestibility of Nutrient and Blood Metabolite in Dairy Cows

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 metabolit

In Vitro Digestibilities of Six Rumen Protected Fat-Protein Supplement Formulas

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.
