Abstract

This research was aimed to find out the change of tea leaves waste fiber on lipid absorption afterbeing fermented by Aspergillus niger and also to be expected as a model to gain healthy livestockproduct. Tea leaves waste was fermented by Aspergillus niger during 6 day. Fifteen of rats with initialweight of 41.17±4.05 g were fed ad libitum by diets containing different levels of unfermented andfermented tea leaves waste as follows: basal diet (R1), unfermented tea leaves waste 5% (R2),unfermented tea leaves waste 10% (R3), fermented tea leaves waste 5% (R4), fermented tea leaveswaste 10% (R5). The results indicated that bioconversion of tea leaves waste in diet (R4 and R5)decreased almost all of fiber fractions (NDF 75.55%; ADF 57.17%; celluloses 26.74%; lignine 31.19%),except hemicelluloses 18.38%, while the treatment did not change the lipid binding rate (2.07 vs 1.98).Also, the result showed that rats fed with diets containing fermented tea leaves waste (R4 and R5) hadreduced cholesterol (86.25;87.4 mg/dl) and triglyceride (47.06; 46.03 mg/dl), but not on HDLcholesterol(29.28; 26.51 mg/dl). It was concluded that bioconversion property of tea leaves waste byAspergillus niger changed fiber fraction and decreased blood lipid.

Abstract

This study aimed to analyze the impact of electronic marketing utilization and to determine the economic determinants to increase the income of small dairy farmers in Boyolali, Central Java, Indonesia. A survey of 80 dairy farmers from the Cepogo District, Boyolali was determined by simple random sampling. The results showed that the average milk production was 8.3 liters/head/day, the revenue of IDR 3,824,000 per month, production costs of IDR 2,105,000 per month, and income of IDR 1,719,000 per month. Furthermore, by using electronics marketing, farmers could sell 40% of their products to coffee shops and generate revenue of IDR 5,411,500, production costs of IDR 2,705,000 and income of IDR 2,706,500. The utilization of the electronic marketing could increase R/C from 2.1 to 2.43. Economic factors that influence income are market prices, transportation and communication costs, marketing costs and distance traveled. Based on the results of the study it can be concluded that the use of the electronic market can expand the market, increase milk prices and ultimately will increase income

Abstract

This study was designed to determine the physiological response of blood and immune organs ofbroiler chickens fed on various concentration of dietary black cumin powder (BCP) during the dryseason. A total number of 100 unsexed one-day old Cobb broiler chicks were used and distributed to 5treatments (control, antibiotics and without BCP, 20 g/kg BCP, 40 g/kg BCP and 60 g/kg BCP) and 4replications (5 birds for each). Physiological responses of blood and immune organs were measured at30 day of age. Addition of BCP to broiler ration did not significantly effects on physical properties ofblood (leukocytes count, erythrocytes count, haemoglobin, hematocrit, monocytes, and eosinophils) andrelative weights of thymus and bursa of fabricius, but significantly (P<0.05) increased relative weightsof spleen when compared to control. It was concluded that the black cumin grinds (Nigella sativa) as afeed additive could not change the physical properties of blood, relative weights of thymus and bursa offabricius, but it increased the relative weight of spleen at the level of 60 g/kg BCP, which could reduceadverse effects of infectious diseases in broiler chicken.

Abstract

The process of pre-extraction is an important stage in the process of collagen synthesis. This stage increases the sensitivity of collagen molecule chains that can affect production yields and collagen properties. The objectives of the study were to synthesize and evaluate halal collagen from Bali cattle’s hide on different -extracting processes. A total of 5 treatments applied in this study, namely: T1 = Ca(OH)2 5% (b/v) ; T2= Ca(OH)2 15% (b/v) ; T3= Ca(OH)2 5% + CH3COOH 5%(b/v) ; T4= Ca(OH)2 15% + CH3COOH 5% (b/v). Each treatment was repeated 4 times. Data were analyzed in a variety of ways using SPSS program. The observed parameters consisted of: 1) yield, 2) viscosity and 3) pH. The results showed that the difference in real pre-extracting process increased the yield and viscosity, but not the pH value. The application of T4 treatment provided the best results compared to other treatments as well as controls to increase the yield and also improve the collagen's physical properties and pH.

Abstract

By mixing with pork, beef adulteration is frequently found in the traditional  market that very disturbing Moeslem community in Indonesia. This study was conducted to detect pork contamination in fresh and cooked beef using genetic marker mitochondrial DNA cytochrome b (mt-DNA Cyt b) by duplex-PCR. A total of twelve samples was used in this study consisting six fresh meat samples and six cooked meat samples, respectively. Those beef and pork were bought from animal slaughterhouse and a supermarket in Surakarta. Cooked samples were prepared by boiling the meats in hot water at 100oC for 30 minutes. We designed pork contamination in beef in the level of 0, 1, 5, 10, 25%, respectively. The DNA genome was extracted and polymerase chain reaction (PCR) was performed using species specific primer to isolate mt-DNA Cyt b gene from the samples. The results showed that the DNA genome was successfully extracted from pork, beef, and contaminated meat samples. In addition, visualization of duplex-PCR on 1.5% agarose gel was able to detect pork contamination in both fresh and cooked beef up to very small proportion (1%). The existence of pork in beef was indicated with the presence of specific 398 bp DNA band. It can be concluded, duplex-PCR of mt-DNA Cyt b gene was very sensitive in detection of pork contamination in fresh and cooked beef.

Abstract

The purpose of this research is to study the interaction between slaughter age and restricted feed, aswell as the influence of each factor on the production of rex rabbits pelt. Randomized Block Designwith Factorial was used in this experiment with the first factor was 3 levels of restricted feedingtreatment where the amount of feed as follow: P1= 100 % from the total feed requirement, P2 = 80%from total feed requirement and P3 = 60% from the total feed requirement. Feed was given in the amountof rabbits requirement, in which 100% of the total requirement was calculated based on body weight(6.7% of body weight in dry matter basis), and second factor was 3 levels of slaughter age (U1= 120 d,U2= 150 d, U3= 180 d) and each treatment was repeated 6 times. The data were analyzed by Anova,and analyzing between the treatments used Contrast Orthogonal. The variable measured were peltproduction (weight pelt, width pelt, thickness dermis and epidermis) of Rex rabbit. There was aninteraction betwen slaughtered age and the amount of feed given to Rex rabbits. Feeding 80% from thetotal feed requirement and the slaughtered age at 150 d were the most efficient in producing pelt of Rexrabbits, with weight 261.0 ± 30.33 g, width 928.0 ± 75.5 cm2, and epidermal thickness 32.50 ± 1.1μ,and dermis 2685.50 ± 15.0 μ.

Abstract

Antibacterial properties of three medicinal plants used widely amongst the native Indonesians, i.e.,sirih (Piper betel), garlic (Allium sativum) and jinten hitam (Nigella sativa) were screened and evaluatedagainst Salmonella sp. isolates. For this purpose, the three plants’ powder, aqueous and ethanol extractswere prepared. The tests’ results demonstrated the three plants’ anti Salmonella sp. activities. In thisconjunction, the aqueous extract of Allium sativum, the ethanol extracts of Nigella sativa, and Piperbetel, consecutively produced 17 mm, 15 mm and 13 mm diameter of bacterial growth inhibition zones.As a comparison, sensitivity tests of three commercial antibiotics, i.e., chloramphenicol, tetracycline,and gentamycin on Salmonella sp. isolates produced 19.7-27.3 mm growth inhibition zones. Garlichaving antimicrobial potential was comparable to the commercial antibiotics, can be used as adecontaminant against Salmonella sp. to maintain the quality of the broiler carcasses and thereforeprolonging the carcass shelf-life.

Abstract

The objective of this study was to determine the effect of live weight (LW) on libido, sperm quality, testosterone, luteinizing hormone (LH) in Ongole grade (OG) bull. This study used 32 heads of OG bull with a completely randomized design that were divided to four different LW groups, i.e. group I was 170 to <210kg, group II was 210 to <250kg, group III was 250 to <290kg and group IV was 290 to 330kg. Parameters: observed were libido, testosterone hormone, LH, and semen quality. Data were analyzed by ANOVA. Libido of OG bull in group II and III higher than those in group IV. The testosterone hormone and LH showed that group II, III and IV were better than group I. The highest LH was in group IV, but low levels of testosterone were observed in these respective groups. Live sperm was the lowest in group I (21.25±13,20%) than II (66.00±11.17%), III (59.80±22.20%) and IV (75,67±9.46%). It can be concluded that the libido, sperm quality, testosterone, LH of OG bull in group II, III and IV were better than those in the group I, therefore standard LW of OG bulls had at least 250 kg.
