Effect of different levels of sunflower meal and multi-enzyme complex on performance, biochemical parameters and antioxidant status of laying hens
No full textThis study was designed to evaluate the effects of different sunflower meal (Helianthus annus; SFM) levels and a multi-enzyme complex (Natuzyme P50) on performance, biochemical parameters and antioxidant status of laying hens. A total of 288 Hy-Line W-36 laying hens (39-wk-old) were divided into six groups with six replicates per group (eight birds per replicate) and fed one of the six experimental diets. A corn-soybean meal-based diet was formulated and used as control diet. The experimental treatments consisted of three levels of SFM (0, 10, and 20%) and two levels of multi-enzyme complex (0 and 250g/ton). The feeding trial lasted 10 weeks. The results showed that the egg production, egg weight and mass, egg specific gravity, shell strength and thickness, Haugh unit, shape index, triglyceride content, plasma glutathione peroxidase (GSH) activity, and malondialdehyde (MDA) were not influenced by dietary treatments; however, the feed consumption, yolk cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol were significantly affected by feeding SFM compared to the control. In conclusion, the supplementation of SFM up to 20% in diet with multi-enzyme complex in laying hens did not appear to cause any adverse effects on egg production and quality as well on antioxidant status in laying hens
Effects of using artemisia annua leaves, probiotic blend, and organic acids on performance, egg quality, blood biochemistry, and antioxidant status of laying hens
No full textThis study was performed to investigate and compare the effects of using Artemisia annua leaves, probiotic, and organic acid on the performance, egg quality, blood biochemistry, and antioxidant status of laying hens. In total, 288 Hy-Line W-36 commercial layers (32weeks old) were divided into six groups with six replicates per group (eight birds per replicate) and were fed one of six experimental diets. The hens were fed either a corn-soybean meal basal diet (control) or the basal diet supplemented with 2.5% A. annua leaves (AA1), 5% A. annua leaves (AA2), 7.5% A. annua leaves (AA3), 0.1% probiotic (Pro), and 0.005% organic acid (Org), respectively. The experiment lasted 10 weeks. Results showed that there were differences in the feed conversion ratio (FCR) among experimental groups (P <0.05). The highest yolk color index and shell thickness were observed in hens fed AA3 and AA2diets (P<0.05). Egg yolk cholesterol was decreased (P<0.01) by the diet containing AA3 and Pro compared to the other groups. The atherogenic index was lower (P<0.01) in the plasma of hens fed AA3 than those in other groups. The glutathione peroxidase activity (GSH-Px) and malondialdehyde (MDA) contents in layers fed AA3 were lower and higher (P< 0.05), respectively, than in layers fed the other diets. Moreover, the concentration of plasma cholesterol was decreased (P<0.05) in layers fed AA3 and Pro. In conclusion, feeding laying hens with A. annua leaves positively influenced the plasma antioxidant status, and the dietary inclusion of A. annua leaves plus a probiotic significantly decreased the egg yolk cholesterol, with no adverse effect on the egg productive traits
Effect of dietary sesame (Sesame indicum L) seed meal level supplemented with lysine and phytase on performance traits and antioxidant status of late-phase laying hens
No full textObjective: This study was performed to investigate the effects of supplementing sesame seed meal (SSM) with phytase and lysine on performance, egg quality, blood biochemical and antioxidant status of laying hens. Methods: A total of 960, 56-wk-old laying hens were divided into 12 dietary groups with eight replicates per group (10 birds per replicate). A completely randomized design with factorial arrangement 2×3×2 consisted of two levels of lysine supplement (0% and 10% over requirement), three SSM levels (0%, 10%, and 20%) with or without phytase (0 and 300 g/ton). The feeding trial lasted 10 weeks. Results: Birds fed diets with 10% SSM had higher feed intake than groups fed 0% and 20% SSM. The addition of phytase to experimental feeds, improved feed conversion ratio, increased egg weight and mass (p<0.01). Egg quality criteria was not affected by supplementing phytase; however, supplementing 300 g/ton phytase to hens diet, led to a significant (p<0.05) increase in egg shell strength. Egg yolk cholesterol and serum low-density lipoprotein cholesterol, atherogenic index and total cholesterol were decreased (p<0.01) by diet containing 20% SSM. The high-density lipoprotein cholesterol was increased (p<0.05) in serum of hens fed 20% SSM than the other groups. It was also observed that total antioxidant capacity and total superoxide dismutase content of hens fed 20% SSM was significantly higher than control group (p<0.05). Conclusion: As from results, dietary supplementation of SSM and phytase had no negative effects on laying hens performance or egg quality while improving the egg oxidative stability

Effects of horsetail (Equisetum arvense) and spirulina (spirulina platensis) dietary supplementation on laying hens productivity and oxidative status
No full textThe purpose of this study was to examine the effect of dietary horsetail (Equisetum arvense) and spirulina (Spirulina platensis) supplementation on performance, egg quality, serum biochemical and antioxidant status of laying hens. A total of 648, 63-week-old Hy-Line W-36 layers were divided into nine groups with eight replicates per group (nine birds per replicate). A feeding trial was conducted under completely randomized design with factorial arrangement 3×3 consisting of three different dietary levels of horsetail supplementations (0, 0.25, and 0.50%, respectively) in combination with three levels of spirulina (0, 1, and 2%, respectively). Results showed that feed intake, egg production, egg weight and mass, and feed conversion ratio were not significantly affected by the dietary treatments. Eggshell thickness, strength, and yolk color were significantly improved in diets supplemented with 0.5% horsetail and 2% spirulina and their interactions. Egg yolk cholesterol was not significantly different among groups; however, a significant reduction was found when fed 2% spirulina. Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentration decreased by supplementing 2% spirulina in diet; also, spirulina increased total superoxide dismutase (TSOD) and total antioxidant capacity (TAC) in laying hens. Overall, the findings indicated that the combination of horsetail and spirulina could have potential for improving the egg’s physical parameters, whereas spirulina was more effective in improving blood traits and oxidative status
Effect of dietary flaxseed meal supplemented with dried tomato and grape pomace on performance traits and antioxidant status of laying hens
No full textThis study was carried out to determine the effect of dietary flaxseed meal (FSM) supplemented with dried tomato pomace (DTP) and dried grape pomace (DGP) on performance, egg quality, biochemical parameters traits and antioxidant status of laying hens. Birds (1825 ± 87 g of body weight) were divided into 12 dietary groups with six replicates per group (eight birds per replicate), under a completely randomized design with factorial arrangement 2 × 3 × 2 consisted of two levels of DTP (0 and 15%), three FSM levels (0, 4 and 8%) and two levels of DGP (0 and 5%). As a result of this study, there were no significant differences in egg production and weight as well in feed conversion ratio (FCR) among treatments (p > 0.05). Feeding of DGP reduced significantly feed intake and egg mass when compared to control group (p < 0.05). There was no effect (p > 0.05) of dietary treatment on shell thickness and strength, shape index, Haugh unit and egg specific gravity. Hens consuming 15% DTP and 5% DGP revealed a significantly higher yolk color compared to the other dietary treatments (p < 0.05). Moreover, there was no difference among dietary treatments in terms of serum low-density lipoprotein cholesterol (LDL) and high-density lipoprotein cholesterol (HDL) cholesterol, atherogenic index, triglycerides, total cholesterol levels (p > 0.05). Serum antioxidant parameters as glutathione peroxidase (GSH-Px) activity, malondialdehyde (MDA), total superoxide dismutase (TSOD) and total antioxidant capacity (T-AOC) were not influenced by treatments (p > 0.05). Based on findings, FSM and DTP supplements did not significantly impact most of hens’ performance indicators and egg quality parameters, whereas significant improvements were observed by feeding of 15% DTP and 5% DGP on egg traits, in particular on egg-yolk color that plays a key-role in consumer’s choice. However, the supplementation of FSM and DTP or DGP even in laying hen diet is still controversial and further research is needed

CNN-Oriented Placement Algorithm for High-Performance Accelerators on Rad-Hard FPGAs
No full textConvolutional Neural Networks (CNNs) are quickly becoming one of the most common applications running on hardware accelerators. Considering Field Programmable Gate Arrays (FPGAs), due to their high flexibility and computational performance, they are suitable for fast classification tasks and therefore, pave the way for new machine learning inference approaches. In this work, we first designed a fully interconnected CNN architecture implementable on a single FPGA. Secondly, we developed a new Neural Node-oriented placement algorithm to enable resilient CNN accelerators on space-grade FPGAs. The proposed solution reduces the single event transient error sensitivity of CNN single neuron cores while achieving high performance and effective overall convolutional architecture fault tolerance. The developed approach has been applied and integrated into a state-of-the-art Radiation Tolerant FPGAs (RTG4) implementation flow. The experimental evaluation has been performed on a Microchip test board through benchmark application performance evaluation and transient error analysis. Experimental results demonstrate an improvement of 27.2% of the maximal working frequency and a reduction of the transient error sensitivity of about three times with respect to the previous mitigation approaches
On the evaluation of SEU effects on AXI interconnect within AP-SoCs
No full textG-Programmable System-on-Chips offering the union of a processor system with a programmable hardware gave rise to applications that choose hardware acceleration to offload and parallelize computationally demanding tasks. Due to flexibility and performance they provide at low cost, these devices are also appealing for several applications in avionics, aerospace and automotive sectors, where reliability is the main concern. In particular, the interconnection architecture, and especially the AXI Interconnection for FPGA-accelerated applications, plays a critical role in these systems. This paper presents a reliability analysis of the AXI Interconnect IP Core implemented on Zynq-7000 AP-SoC against SEUs in the configuration memory of the programmable logic. The analysis has been conducted performing a fault injection campaign on the specific section of the configuration memory implementing the IP Core under test, which has been implemented within a benchmark design. The results are analyzed and classified, highlighting the criticality of the AXI Interconnect IP Core as a point of failure, especially for SEU-hardened hardware accelerator relying on mitigation techniques based on fine-grained and coarse-grained replication
