Abstract

Quality of meat can be assessed from the change of its chemical components.  Characteristics of meat chemical composition depend on species, age, sex, feed, location and function of muscle section in body.  The objective of the research was to study meat chemical composition of local male sheep on different slaughter weight and different muscle. Local male sheep which were used as subject research obtained from Temanggung, i.e. healthy male sheep, aged 1.5-12 months; slaughtered at 6 categories of slaughter weight ranging from 5 to 30 kg.   The sheep was slaughtered and sampled for chemical composition determination of Longissimus dorsi (LD) dan Biceps femoris (BF). The nested ANOVA was used to analyze data and any differences among the groups were further tested using Duncan Multiple Range Tests (DMRT).  The results showed that moisture, ash, fat and cholesterol content of the meat from different slaughtered weight were not significant (P>0.05).  The increase of slaughter weight significantly (P<0.05) increased the protein content of meat.  Protein content of meat from 7, 10, 15, 20, 25 and 30 kg slaughtered weight were 18.44; 17.83; 18.70; 19.58; 19.44 and 20.06%, respectively. Vitamin A content from different slaughter weight were significant (P<0.05).  Vitamin A content of meat from 7, 10, 15, 20, 25 and 30 kg slaughter weight were 682.06; 587.10; 612.59; 590.93; 663.32 and 590.84 µg/100 g meat, respectively.  Moisture, ash, protein, fat, cholesterol and vitamin A from LD and BF muscle were not significant (P>0.05).  The conclusion of the research were (1) moisture, ash, fat and cholesterol content of local male sheep meat from different slaughtered weight were not significant, but protein and vitamin A content of the meat from different slaughtered weight were significant, (2) chemical composition of local male sheep from LD and BF were not significant.

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
