Abstract

This study aimed to evaluate the role of broiler feed standards using the Analytic Network Processing (ANP) method. Data were taken from five feed manufacturing companies, three feed experts and three government institutions in the feed sector. There were 3 criteria and 6 sub-criteria in determining the best alternatif out of 6 feed evaluation in the context of implementing broiler feed quality and safety standards. The results showed that the greatest sub-criteria weight was effectiveness (0.750). In addition, the selected alternatif analysis with the highest weight was proximate analysis (0.315; 0.280) in the assessment by feed companies and the government and followed by amino acids analysis (0.365) in the assessment by feed experts. From the results, all entities assessed the proximate analysis as a priority because proximate testing on animal feed could help to determine the nutritional quality of feed by knowing the content of protein, fat, crude fiber, and other nutrients in the feed. This study was concluded that proximate testing was very important in the animal feed industry because it could help in determining the nutritional quality of animal feed, optimizing livestock growth and production, preventing nutritional deficiencies in livestock, determining the selling price of feed, and guaranteeing feed quality. Key words: ANP, feed quality and safety testing, feed standards, quality control and feed safety

Abstract

This study aimed to evaluate separation method to reduce the shells of palm kernel cake (PKC) and to optimize the extrusion process to increase the nutrient utilization. The sieving process was a method of separating two materials that had different sizes, both solid and liquid materials. The extrusion process variables used in this study were extrusion temperature and moisture content of PKC as optimization variables in the response surface methodology (RSM). The RSM design was central composite design (CCD) with 13 treatments and analysed with Design Expert version 13. PKC was separated from its shell by filtering it at a size of ≤0.600 mm and continued the extrusion process for 13 treatments using temperatures starting from 72 to 128 °C and moisture content starting from 22 to 78%. The main variable response was crude protein (CP), crude fibre (CF), and ether extract (EE). Based on statistical analysis, it was found that temperature and moisture content had a significant effect (p<0.05) on the mathematical model of the relationship between the independent variables (temperature and moisture content) and the best CP, CF and EE responses. PKC extrudate had a bulk density value of 420 kg m-3 and a total solubility of 24.11%. The conclusion of this study was that the optimal extrusion treatment at BIS was using 91 °C and 42% moisture content to produce the best chemical and physical qualities.

Abstract

ABSTRAK Limbah pertanian pada umumnya memiliki kandungan protein, kecernaan, dan palatabilitas yang rendah disamping itu sifatnya yang voluminous menyulitkan dalam penanganan, baik pada saat transportasi maupun penyimpanannya, sehingga memerlukan suatu cara untuk meningkatkan nilai guna limbah pertanian. Klobot jagung merupakan salah satu limbah yang dapat dimanfaatkan sebagai sumber serat, karena kandungan seratnya tinggi yaitu sebesar 32%. Kendala yang dihadapi dalam penggunaan klobot jagung sebagai pakan ternak yaitu sifatnya yang voluminous, sehingga masih belum banyak dimanfaatkan sebagai pakan ternak. Untuk memudahkan penyimpanan dan menjaga ketersediaannya maka klobot jagung dimanfaatkan dengan pengolahan fisik dalam bentuk wafer. Tujuan penelitian ini untuk mengetahui taraf terbaik dari klobot jagung yang dapat digunakan sebagai substitusi sumber serat pengganti rumput lapang di dalam wafer ransum komplit untuk domba ditinjau dari kualitas sifat fisik yaitu kadar air, kerapatan wafer, daya serap air, dan palatabilitas. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan yang dicobakan adalah: ransum yang mengandung 30% rumput lapang + 70% konsentrat (R1); ransum yang mengandung 20% rumput lapang + 10% klobot jagung + 70% konsentrat (R2); ransum yang mengandung 10% rumput lapang + 20% klobot jagung + 70% konsentrat (R3); dan ransum yang mengandung 30% klobot jagung + 70% konsentrat (R4). Variabel yang diukur adalah kandungan air, densitas, penyerapan air, dan palatabitas dari wafer klobot jagung. Hasil penelitian menunjukkan bahwa perlakuan R2 dan R3 berpengaruh terhadap kandungan air (p<0,05). Perlakuan R2, R3, dan R4 berpengaruh sangat nyata terhadap daya serap air (p<0,01), tetapi tidak berpengaruh terhadap densitas. Nilai kandungan air berkisar antara 9,39%-12,61%, dan nilai densitas berkisar antara 0,70 g/cm3-0,75 g/cm3, sedangkan nilai palatabilitas wafer berkisar 550-885 g/hari. Dari penelitian ini dapat disimpulkan bahwa klobot jagung dapat digunakan sebagai pengganti rumput sebagai bahan pakan alternatif sampai 20% pada ransum komplit untuk domba. THE UTILIZATION OF CORN HUSK AS COMPLETE RATION WAFER FOR SHEEP ABSTRACT Generally, agricultural waste contain low protein, digestibility, and palatability, while its property is voluminous, so its difficult on handling either at transportation or storage. We need a special way for increasing the value of agricultural waste. Corn husk is one of agricultural waste that can be used as source of fiber, in which its contain 32% of fiber approximately. However, there is a problem to use corn husk as animal feed, in which its has voluminous property, so the utility of corn husk still not more used yet as animal feed. To facilitate its storage and keep availability, the corn husk must be made with physical processing as wafer form. Objectives of this research were to know the best level of corn husk that can be used to substitut roughage as fiber source in completely feed for sheep with wafer form, and to know the physical quality and palatability of corn husk wafer. Experimental method that used in this research was Completely Randomized Design with 4 treatments and 3 replications. The four treatments were ration for sheep, consist of R1 (30% field grass + 70% concentrate), R2 (20% field grass + 10% corn husk + 70% concentrate), R3 (10% field grass + 20% corn husk + 70% concentrate) and R4 (30% corn husk + 70% concentrate). The results were analyzed by using Analysis of Variance (ANOVA) and to be continued with Contras Orthogonal if the effect of treatments were different significantly. Variables to be measured were water content (%), density (g/cm3), water absorption (%) and palatability of corn husk water. The result show that treatments of R2 and R3 influenced to water content significantly (P<0.05). The treatments of R1, R2, R3 and R4 influenced the increase of water absorption with very significant (P<0.01), but their effect were not significant to density. The average values of water contain were ranging between 9.39% to 12.61%. The average of density values were ranging between 0.70 g/cm3 to 0.75 g/cm3 and the values of palatability of water were ranging between 550-885 g/day. Based on the research results above, the corn husk can be used to replace serious grass as alternatively animal feed until 20% of water in completely feed for sheep.

Abstract

Antibiotics Growth Promoter (AGP) are currently banned. Citrus leaves have active secondary metabolites that have the potential to be used as phytogenic feed additives. Many in vitro studies have reported the activity of lime leaves against E coli. Therefore, this study aims to integrate various studies in order to obtain comprehensive information on the activity of lime leaves against E coli with a meta-analysis. This research was conducted by collecting studies of citrus leaves from various species, origin, extraction methods, and different antibacterial test methods and comparing the treatment of citrus leaves with controls in inhibiting E coli by looking at the diameter of the inhibition zone. The results showed that kaffir lime leaves as an alternative phytogenic feed additive for AGP were effective in inhibiting E. coli. The inhibitory ability of E. coli bacteria was based on differences in the origin of lime leaves and extraction methods, while differences in levels, types of lime leaves, and antibacterial test methods did not affect the inhibition of E. coli. Citrus leaf extract at a low concentration of 5 mg/ml was able to inhibit E coli bacteria. Keywords: escherichia coli, lime leaf, meta-analysis

Abstract

The effect of reduction of maize as starch source on flow rate of pellet in continuous production processABSTRACT. This experience was conducted to determine effect of reduction of maize as starch source on flow rate of pellet in continuous production process. Design of the experiment used was a completely randomized design with 3 treatments and 3 replicates. The data is analyzed by using of ANOVA and if there is a significance among treatments would tested using by contrast orthogonal. The variables observed were angle of repose, loose bulk density, compacted bulk density, and flow rate. The results showed that the reduction of maize as starch source did not give the significant effect on the variable that observed. The analyzed angle of repose showed variation 24.200 to 25.690, loose bulk density showed variation 621.6kg/m3 to 658kg/m3, compacted bulk density showed variation 668.3kg/m3 to 676.8kg/m3, and flow rate showed variation 449.69kg/minute to 491.41kg/minute. Based on the result that the reduction of maize as starch source (corn, sorghum, menir) did not give the significant effect on flow rate of pellet and the pellet treatment with menir has the fastest pellet production time so flowability pellet from pelleter to material hadling (bucket elevator) machine is faster. As higher the values of flow rate, so the time of material movement from bin to the package is shorter.

Abstract

The provision of feeder sheep is a problem for farmers due to a high mortality rate among pre- and post-weaned lambs. Whey protein contains amino acids, glucose, and immunoglobulin which facilitate immunity enhancement and body weight gain. This study aimed to evaluate the effectiveness of supplementing whey protein wafer on the performance and profile of weaning sheep. A total of 12 ewe were randomly allotted to 3 treatments: P0 (non-supplemented feed); P1 (1.5% whey protein wafer supplement; and P2 (3% whey protein wafer supplement). Each treatment was replicated four times. The results showed that the whey protein wafer supplement treatment significantly (P<0.05) affected erythrocytes, leukocytes, monocytes, glucose, and cholesterol. Wafer with 3% whey protein supplement showed the best average daily gain, a normal range of blood profile, and a good performance compared to other treatments. The normal blood profiles reflect the sound health of the sheep.

Abstract

The content of active compounds in natural materials is generally low and highly variable, thus requiring efficient and selective extraction methods. This study aims to evaluate a stepwise extraction process applied to the seeds, oil, and by-products of Nigella sativa (black cumin) to obtain thymoquinone (TQ) and other phytochemicals. The study consisted of four main stages: (1) extraction of HS oil using the cold press method, (2) stepwise extraction using 70% ethanol as solvent, (3) analysis of TQ content and phytochemical compounds in the extracts, and (4) evaluation of the antibacterial activity of habbatussauda oil extracts against pathogenic and non-pathogenic bacteria. Results showed that the cold press method yielded 34.46% oil. Stepwise extraction using 70% ethanol resulted in significant differences (p<0.05) in both yield and TQ content among the seed, oil, and by-product extracts. Among all samples, the ethanol extract from habbatussauda oil exhibited the highest yield and TQ concentration. Furthermore, at a concentration of 100 μg mL⁻¹, this extract inhibited the growth of pathogenic bacteria such as Salmonella typhimurium and Escherichia coli, without affecting non-pathogenic strains like Lactobacillus spp. and Bifidobacteria spp. In conclusion, stepwise extraction using 70% ethanol proved effective in enhancing TQ recovery and demonstrated potential as a phytobiotic agent with selective antibacterial activity against pathogenic bacteria.
