Effect of a by-product of solid state fermentation (Synergen™) on broiler performance

The trial was conducted to evaluate the effect of a by-product of solid state fermentation (Synergen™ (SGN), Alltech Inc, Nicholasville KY, USA) on broiler performance and health. One thousand two hundred and eighty male Ross 308 broilers were used in a 42 day pen trial. The trial was designed as a 2×2 factorial, with two diet specifications (standard and reformulated) plus or minus SGN (0 and 200g/t, SGN replaced with commercial enzyme Ronozyme™ at 150g/t) to give four dietary treatments in total in a corn-soy based diet formulated to commercial standards. Birds fed the reduced energy diets had significantly lower cumulative feed intakes at 42 d (P<0.01) compared to those on the full specification standard diet. There were no significant differences in broiler body weight due to treatments at any age. Significant improvements (P<0.05) in FCR, primarily due to SGN inclusion in the feed, were observed for all weekly reported data. There were no significant differences in either mortality or EPEF for any of the treatment diets. The present study indicates that SGN, a by-product of solid state fermentation (SSF) can improve feed conversion of broilers fed a corn-soy die

Studies of Corrosion Resistance of Passive Layers on Al-Ni Alloys in the Presence of Chloride Ions

The corrosion resistance of passive layers was studied on cast Al-Ni alloys with an ever-increasing mass content of nickel («;(Ni) = 0.54 - 4.30%). The method of potentiodynamic polarization, measuring to 10 V, the method of measuring the changes of the current at a constant potential of 0 V, and the method of determining the critical concentrations of chloride ion gave identical dependence of the corrosive resistance of the passive layers on the mass content of nickel in the alloy. The method of potentiodynamic polarization at low potentials to 1 V was applied to obtain the dependence of insulating properties of the passive layers on the mass content of nickel in alloy

Uticaj multifazne ishrane na proizvodne performanse brojlera

Multiphase broiler nutrition is important from the standpoint of nutrition optimization, economical efficiency of production and protection of the environment. Objective of research is to investigate the effect of multiphase nutiriton, i.e. different mixtures used in broiler nutrition, whse protein content has been reduced in several phases during first fattening stage, on production performances of broilers. Investigation was carried out on 608 individually tagged male chickens, Ross 308 strain, divided into 4 groups: T1 (control group) - nutrition with mixture containing 23% of protein from 1-21st day; T2 - nutrition with mixture containing 23% of protein from 1st to 7th day, and from 7th to 21st day diet containing 21.5% protein; T3 - nutrition with mixture containing 23% of protein from 1st to 14th day and from 14th to 21st day diet containing 21.5% protein and T4 - nutrition with mixture containing 23% of protein from 1st to 3rd day, from 4-6th day with 22.55% protein, 7-9th day with 22.10% protein, 10-12th day diet with 21.65% protein, 13 - 15th day with 21.20% protein, 16-18th day with 20.75% protein and 19th-21st day diet with 20.30% protein. Main production parameters were registered during the trial period (from 1 to 21st day).Through processing of obtained data it ewas established that chickens of the T4 group (2092.42g), had realized statistically significantly higher body mass compared to T2 (2025.00g) and T3 (2020.07g), but not in relation to control group T1 (2055.16g), during trial period of 42 days. Also, it can be concluded that in regard to daily gain in period up to 21st day, no statistically significant differences between trial groups were established, however, for the entire trial period, average daily gain of chickens in T4 group (48.84g) was statistically considerably higher compared to T2 (47.24g) and T3 (47.13g), whereas in relation to T1 no differences were established T1 (47.99). Feed conversion differed between groups, precisely in favor of the application of multiphase broiler nutrition, i.e. feed conversion of the trial group T4 (1.870) was the best compared to T1 (1.918), T2 (2.005) and T3 (1.970). Based on obtained results it can be concluded that multiphase nutrition had effect on production performances, primarily level of food utilization.Multifazna ishrana brojlera je značajna sa aspekta optimiziranja ishrane, ekonomičnosti proizvodnje i zaštite životne sredine. Cilj istraživanja je da se ispita uticaj multifazne ishrane, odnosno različitih smeša za ishranu brojlera, u kojima je sadržaj proteina smanjen višefazno u prvoj fazi tova, na proizvodne osobine tovnih pilića. Ispitivanje je izvedeno na 608 individualno obeleženih pilića muškog pola, provenijence Ross 308, podeljenih u četiri grupe: T1 (kontrolna grupa) - ishrana smešom sa 23% proteina u trajanju od 1-21 dana; T2 - ishrana od 1-7 dana smešom sa 23% proteina i od 7-21 dana sa 21,5% proteina; T3 - ishrana od 1-14 dana smešom sa 23% proteina i od 14-21 dana sa 21,5% proteina i T4 - ishrana 1 -3 dana smešom sa 23% proteina, 4-6 dana sa 22,55% proteina, 7-9 dana sa 22,10% proteina, 10-12 dana sa 21,65% proteina, 13-15 dana sa 21,20% proteina, 16-18 dana sa 20,75% proteina i 19-21 dana sa 20,30% proteina. U oglednom periodu (od 1-42 dana) praćeni su osnovni proizvodni parametri. Obradom podataka utvrđeno je da su pilići T4 grupe (2092,42g), ostvarili statistički značajno veću telesnu masu u odnosu na T2 (2025,00g) i T3 (2020,07g), ali ne i u odnosu na kontrolnu T1 grupu (2055,16g), u oglednom periodu od 42 dana. Takođe se može konstatovati da za dnevni prirast u periodu do 21. dana nisu utvrđene statistički značajne razlike između oglednih grupa, međutim posmatrano za ceo ogledni period, prosečan dnevni prirast T4 grupe (48,84g) bio je statistički značajno veći u poređenju sa T2 (47,24g) i T3 (47,13g), dok nije bilo razlika u poređenju sa T1 (47,99) oglednom grupom. Konverzija hrane razlikovala se između grupa, upravo na način koji govori u prilog primeni multifazne ishrane brojlera, odnosno konverzija ogledne T4 grupe (1,870) bila je najpovoljnija u poređenju sa T1 (1,918), T2 (2,005) i T3 (1,970). Na osnovu dobijenih rezultata može se zaključiti da je multifazna ishrana imala uticaj na proizvodne performanse, a prevashodno na stepen iskorišćavanja hrane

Influence of dietary mannanoligosaccharides on histological parameters of the jejunal mucosa and growth performance of broiler chickens

The trial involved 480 Hubbard Classic broiler chicks which were from either mannanoligosaccharide (MOS) fed breeder flock (Bio-Mos, Alltech Inc. USA at level of 1 kg/t) or control fed breeder flock (without MOS). Three groups with four replicates per treatment were formed: control fed breeders/control fed broilers (C/C); MOS fed breeders/control fed broilers (BM/C) and MOS fed breeders/MOS fed broilers (BM/BM). All chicks were fed the same basal diet, except for the inclusion of Bio-Mos (1, 0.75 and 0.5 kg/t in the starter, grower and finisher diet, respectively). The results showed a significant improvement (p&lt;0.05) in the body weight gain with the addition of Bio-Mos in broiler feed. Feed conversion ratio was improved by 0.03 points, but the difference was not significant (P&gt;0.05). The gut morphology examination showed that chick origin (chicks that originated from Bio-Mos fed breeders or control fed breeders) did not influence the morphological parameters of the jejunum in the broiler chickens, but addition of Bio-Mos directly to the broiler feed had a significant influence on the gut morphology and played an important role in processes of digestion and absorption, leading to improved performance.Key words: Broiler, mannanoligosaccharides, growth, jejunum, histology

Irradiation study of a fully monolithic HV-CMOS pixel sensor design in AMS 180 nm

High-Voltage Monolithic Active Pixel Sensors (HV-MAPS) based on the 180 nm HV-CMOS process have been proposed to realize thin, fast and highly integrated pixel sensors. The MuPix7 prototype, fabricated in the commercial AMS H18 process, features a fully integrated on-chip readout, i.e. hit-digitization, zero suppression and data serialization. It is the first fully monolithic HV-CMOS pixel sensor that has been tested for the use in high irradiation environments like HL-LHC. We present results from laboratory and test beam measurements of MuPix7 prototypes irradiated with neutrons (up to $5.0\cdot10^{15}{\,\rm{n}_{\rm{eq}}/cm^2}$) and protons (up to $7.8\cdot 10^{15} \,\rm{protons}/cm^2$) and compare the performance with non-irradiated sensors. Efficiencies well above 90 % at noise rates below 200 Hz per pixel are measured. A time resolution better than 22 ns is measured for all tested settings and sensors, even at the highest irradiation fluences. The data transmission at 1.25 Gbit/s and the on-chip PLL remain fully functional

The MuPix Telescope: A Thin, high Rate Tracking Telescope

The MuPix Telescope is a particle tracking telescope, optimized for tracking low momentum particles and high rates. It is based on the novel High-Voltage Monolithic Active Pixel Sensors (HV-MAPS), designed for the Mu3e tracking detector. The telescope represents a first application of the HV-MAPS technology and also serves as test bed of the Mu3e readout chain. The telescope consists of up to eight layers of the newest prototypes, the MuPix7 sensors, which send data self-triggered via fast serial links to FPGAs, where the data is time-ordered and sent to the PC. A particle hit rate of 1 MHz per layer could be processed. Online tracking is performed with a subset of the incoming data. The general concept of the telescope, chip architecture, readout concept and online reconstruction are described. The performance of the sensor and of the telescope during test beam measurements are presented.Comment: Proceedings TWEPP 2016, 8 pages, 7 figure

MuPix7 - A fast monolithic HV-CMOS pixel chip for Mu3e

The MuPix7 chip is a monolithic HV-CMOS pixel chip, thinned down to 50 \mu m. It provides continuous self-triggered, non-shuttered readout at rates up to 30 Mhits/chip of 3x3 mm^2 active area and a pixel size of 103x80 \mu m^2. The hit efficiency depends on the chosen working point. Settings with a power consumption of 300 mW/cm^2 allow for a hit efficiency >99.5%. A time resolution of 14.2 ns (Gaussian sigma) is achieved. Latest results from 2016 test beam campaigns are shown.Comment: Proceedingsfor the PIXEL2016 conference, submitted to JINST A dangling reference has been removed from this version, no other change

Novel high-speed monolithic silicon detector for particle physics

This contribution presents simulation results, implementation, and first tests of a monolithic detector developed at KIT. It consists of a sensor diode tightly integrated with an analogue front-end based on SiGe (Silicon-Germanium) SG13G2 130 nm BiCMOS technology produced at the Leibniz Institute for High Performance Microelectronics (IHP). The pixel size is 100 μm × 100 μm, and the nwell charge collection node dimensions were reduced to 10 μm × 10 μm. We investigate the influence of this approach on sensor performance, spatial resolution via charge sharing and timing behaviour
