Abstract

Energy utilization is affected by protein-energy balance in the feed. The purpose of this studywas to determine the optimum balance of crude protein (CP) and total digestible nutrients (TDN) in a feed efficiency on the native sheep, by looking at the ability of the utilization of energy from the feed. 24 male native sheep with an average of initial body weight around 18±3.1 kg (CV=17.15%), were used and designed with a completely randomized design (CRD) into 6 dietary treatments of complete feed: Treatment 1 (CP 18.84% and 61.56% TDN), Treatment 2 (CP 16.29% and 66.51% TDN), Treatment 3 (CP 19.94% and 60.29% TDN), Treatment 4 (CP 19.40% and 67.31% TDN), Treatment 5 (CP 20.88% and 60.47% TDN), Treatment 6 (CP 20.12% and 63.05% TDN). Data were analyzed by analysis of variance. Results of DM intake between treatments were not significantly different (P>0.05). The average intake of DM of the study was 775.6 g/day. Energy intake in each treatment was not significantly different (P>0.05) (14.27±1.7 MJ/day). Different ratio of CP and TDN on digested amount of energy in each treatment were not significantly different (P>0.05). Average metabolized energy in native sheep in this study was 6.28 ± 0.9 MJ/day (P>0.05). Conclusion from this research is the different balance of CP and TDN in this study do not have any impact on energy utilization and body weight gain (ADG) of native sheep.Key words: sheep, ratio of CP and TDN, energy feed utilization

Abstract

The aim of this research was to determine the NDF and ADF content of rice strawfermented with several types of microorganism at different temperatures. Rice straw wasobtained from rice fields in Ishigaki District, Okinawa, Japan. The types of microbes usedwere Lactobacillus fermentum, Bacillus subtilis, Bacillus coagulant Saccharomycescerevisiae, and Aspergillus niger. The mainplot was temperature (25, 35, 45°C) and thesubplot was microorganism. Each treatment has 3 replications. There were two groups forcontrols, i.e. the control without molasses and the control with molasses. The rice strawfermented within 3 weeks. The ADF content in all temperature treatments showed that S.cerevisiae and A. niger treatments were higher (P<0.01) than that in other microorganismtreatments. Hemicellulose content in S. cerevisiae and A. niger were tend to lower (P<0.01)compare to others microorganism treatments in all temperature treatments. The lowesthemicelluloses content of fermented rice straw are showed by S. cerevisiae and A. niger at45°C. These finding suggested that the ADF content were high in S. cerevisiae and A. nigertreatments, but showed decrease in hemicellulose and increase in cellulose and lignin.Key words: rice straw, fermentation, ADF, NDF

Abstract

The aim of the study was to assess microbiological properties of beef sold in various meatshops in Semarang. There are five Indonesian goverment standard requirements to maintain the qualityof beef sold in Indonesia markets, as follows: (1) total plate count (TPC) for a maximum of 106 CFU/g,(2) total coliform bacteria for a maximum of 102 CFU/g, (3) total Escherichia coli up to 10 CFU/g, (4)total Staphylococcus aureus for a maximum of 102 CFU/g and (5) negative for Salmonella per 25 gsamples (SNI 3932, 2008). Beef samples were randomly taken from several traditional markets, meatshops and supermarkets. The result showed that all samples did not contain Salmonella but still couldnot meet one or some of the Indonesian government standard regulation. In conclusion, beef samplesgathered from some of the markets, generaly could not meet one or some of the five strictlyrequirements of the bacteriological properties.

Abstract

Eight bulls of Ongole Crossbred (OC) cattle with initial body weight (BW) of 297 + 26 kg (CV =8.75%) fed rice straw treated with urine (RU) (ad libitum) were divided into two groups (each fourheads) to determine the effect of concentrate feeding level on efficiency of eating behavior. The cattlewas given concentrate feeding composed of beer cake and rice bran to make 14% crude protein at 1%and at 2% BW for RUC1 and RUC2 group, respectively. Eating behavior was measured for 3x24 hoursand was performed twice at weeks 2 and 6 of the study. Data obtained were analyzed by t-test. Theresults showed that the level of concentrate feeding affected the intake of urinated rice straw (P<0.01)and daily BWGain (P<0.05), but the effect was not found (P>0.05) on DMI, length time for eating(196.5 vs. 221.5 min/d), length time for rumination (351.0 vs. 449.4 min/d), efficiency of eating time(37.21 vs. 37.67 gDM/min) and efficiency rumination time (21.43 vs. 18.50 gDM/min). This researchshowed that concentrate feeding at 2% BW did not alter the efficiency of eating time and ruminationcompared to 1% BW, although able to improve BWG of OC cattle.

Abstract

The study was carried out to investigate the effect of marination, performed by soaking of beef ingarlic juice, on microbiological and physical properties. The study was committed to a completelyrandomized design, with 5 treatments, i.e.: T0 (unmarinated beef, as a control), T1, T2, T3, and T4 thatbeef were marinated in garlic juice for 5, 10, 15, and 20 minutes, respectively, at room temperature(25⁰C). Each treatment consisted of 4 replications. Examination upon experimental parameters wasconducted after marinated (and control) beef was stored for 8 hours at room temperature. Total bacteria,total coliform and water holding capacity of beef were significantly (P<0.05) affected by marinationwith garlic juice. Conversely, cooking loss was not significantly affected (P>0.05) by the treatments. Asa conclusion, marination of beef with garlic juice could reduce total bacteria, total coliform, and waterholding capacity, but could not reduce cooking loss.

Abstract

This study was aimed to evaluate the effect of dietary energy level on daily gain of Madura cattle and their blood metabolites (glucose and blood urea). Twelve (12) male Madura cattle aged at 2 years old, 156.27+6.92 kg (CV 4.43%) of body weight were used in this study which was assigned to completely randomized design for three feeding treatments (low, middle and high energy contents) and four replications. The daily gain was measured for 90 days, while the blood metabolites were measured at the middle of experiment. Results showed that dietary energy levels did not affect (P>0.05) average daily gain, dry matter intake, dry matter digestibility, energy intake and feed conversion ratio. Blood glucose and blood urea concentration were ranged at 67-75 and 35-50 mg/dL, respectively, while feed energy efficiency reached 0.145 MJ/g ADG. In conclusion, high-level energy could not provide better performance in Madura cattle because of a limitation factor on the DMI.

Abstract

This study aimed to explore physical characteristics and its correlation to feed digestibility in goat.Sixteen Ettawah Grade goats in the second milk production periods and in the 4-5th month of lactationwere used in this study. The study was arranged with completely randomized block block design basedon milk production as replications. The goats were fed ration containing 16% of crude protein and 65%of total digestible nutrients (TDN). Some of crude protein content were supplied by urea. The treatmentswere control ration (without urea; T0), ration with 0.4% urea (T1), ration with 0.8% urea (T2), andration with 1.2% urea (T3). Parameters observed were feed digestibility, fecal extended level (FEL), andfecal rough particle distribution (FRPD). Data were analyzed using correlation-regression to find thecorrelation between fecal characteristics and feed digestibility. The results showed that urea content inthe rations up to 1.2% of dry matter did not affect dry mater digestibility, water content and fecalcharacteristics (FEL and FRPD). There were highly negative correlation (r= -0.665) between feeddigestibility and water content of feces as well as feed digestibility and FEL (r= -0.553), whilecorrelation between digestibility and FRDP was positive (r=0.608). The conclusion of this study waswater content, degree of FEL and FRPD can be used to determine the quality of feed. If feces composedof finer texture, dried and small particles indicated having better digestibility, while if feces composed ofrough texture, wet, and large particles indicated having low digestibility.

Abstract

Each four young bulls of Madura cattle and Ongole Crossbred (OC) cattle were used to study theefficiency of ruminal fermentation by comparing the proportion of Volatile Fatty Acid (VFA) of thesetwo breeds which were raised under intensive feeding. All the cattle were in about 1.5 years-old with anaverage body weight of 147.75 ± 14.57 kg and 167 ± 22.57 kg, for Madura and OC cattle, respectively.They were fed Napier grass (Pennisetum purpureum) hay, and concentrate feeding consists of pollard,soybean meal and rice bran for 10 weeks. Parameters measured were concentration of VFA at 0, 3 and 6h post-feeding and pH. The concentration of VFA in both Madura and OC cattle was peaked at 3 h postfeeding,being 136.1 mmol and 158.9 mmol, respectively, and then were decreased at 6 h post-feeding ata level of 58.1 and 98.2 mmol, respectively. The proportion of acetic acid in Madura and OC cattle were53.33% and 52.0% of total VFA, respectively, while the proportion of propionic acid and butyric acidwere 28.80% and 17.87% for Madura cattle, and 30.71% and 17.28% for OC cattle, respectively. Inaddition, the Acetic/Propionic ratios were 1.85 and 1.69 for Madura and OC cattle, respectively. RumenpH conditions of both cattle breeds tended to be basic, i.e. Madura cattle was ranged at 8.0-8.4, while thePO cattle was ranged at 7.6-8.4. In conclusion, both cattle breeds (Madura and OC cattle) have a similarefficiency to utilize the feeds in the rumen.

Abstract

A study was carried out to assess dietary energy utilization in male fat-tailed sheep being fed duringthe day and/or at night. This study were used 12 rams of 12-18 months old with average of initial bodyweight of 27.05±2.9 kg (CV = 10.74%). The experimental design used in this study was a completelyrandomized design (CRD) with 3 treatments and 4 replications. The treatments were feeding during theday (06.00-18.00; DF), feeding at night (18.00-06.00; NF), and feeding all day and night (06.00-06.00;DNF). The diet was offered ad libitum. The results showed that feeding during the day and/or at nightdid not significantly affect (P>0.05) all parameters observed. The average of dry matter intake (DMI),average daily gain (ADG), gross energy intake (GEI), energy digestibility (DE) and energymetabolizability (ME) were 1006 g/d, 75 g/d, 19.2 MJ/d, 74.0% of gross energy, and 66.2% of grossenergy, respectively. The feed efficiency ratio (FCR), gross energy efficiency, digestible energyefficiency, and metabolizable energy efficiency were 7.38%, 3.86 g ADG/MJ, 5.24 g ADG/MJ, and 5.84g ADG/MJ, respectively. It is concluded that time of feeding did not affect the dietary energy utilizationin local rams.
