Strategy for Improving Production Performance and Quality of Layer Eggs by Giving Symbiotics (Inulin and L. Fusiformis BIP-211 isolate) Through Feeding

Symbiotic is a combination of pre-biotic and pro-biotic. This study aims to evaluate the impact of giving symbiotics through feeding on the performance and quality of layer eggs. This study used 408 Layer 65 weeks old which were divided into 2 groups as treatment. Layer maintenance was carried out for 14 days in a closed house cage with a battery cage system. The treatment in this study was giving symbiotic through feeding (0.1% of feeding) and without symbiotic as a control. The symbiotic used consisted of inulin, mineral mix, and L. Fusiformis BIP-211 bacterial isolates with a cell density of 1012. Parameters observed were production performance [(Feed Intake (FI), Hen Day Production (HDP) and Feed Conversion Ratio (FCR)], Feed digestibility [Dry matter digestibility and organic matter digestibility] and egg quality [(shell thickness, Egg Yolk Index (EYI), Haugh Units (HU), and Egg Yolk Color (EYC)]. The data obtained was analyzed using the T-Test. The results showed that giving symbiotics through feeding had a very significant effect (P-0.000) on HDP and FCR, but not significantly different on FI (P-0.900). The average FI in this study was 102 g/day. The HDP and FCR in the layer that were given the symbiote were 87.6% and 1.8 respectively, while those that without symbiotic were 81.16% and 2.02, respectively. Feed containing symbiotics had a higher level of digestibility of dry matter and organic matter compared to the control (P-0.000). The digestibility of dry matter and organic matter in this feed was 95.5 and 96.07% respectively. Symbiotic administration had a very significant effect (P-0.000) on shell thickness and had no significant effect on EYI, HU, and EYC. The conclusion of this study is that the administration of symbiotics can improve the performance and feed digestibility of layer production and increase the shell thickness without affecting egg quality.

Exploring the potential of black soldier fly live larvae as a sustainable protein source for laying hens: A comprehensive study on egg quality

Live insect larvae were recently proposed for use in laying hens in intensive chicken farming as an innovative form of environmental enrichment. This study aimed to evaluate the effect of laying hen age and feeding with live Black Soldier Fly larvae (BSFL) on egg quality attributes, i.e., chemical composition, fatty acid (FA) profile, and metabolic profile using nuclear magnetic resonance (NMR) spectroscopy. To this aim, 108 Lohman Brown hens were housed in 27 cages (9 replicates per treatment, 4 birds per pen) and monitored between 16 and 34 weeks of age. The hens were split into three experimental groups: a control group fed a commercial diet, and two experimental groups fed the same commercial diet plus 15% or 30% of live BSFL, as fed basis on the expected daily feed intake (DFI). The experimental treatments did not affect the egg and eggshell quality attributes. The supplementation with live BSFL did not influence the chemical composition in terms of macronutrients or the main NMR profiles of egg yolk and albumen. The FA profile of the egg yolk significantly changed as the eggs from hens fed BSFL presented higher rates of SFA and PUFA (P<0.05), lower rate of MUFA (P<0.001), and higher rates of C18:2n 6 (P<0.05) and C18:3 n3 compared to the control eggs (P<0.001). There were no significant differences in the ratio of n-6 to n-3 PUFA. The age of the hens strongly affected egg quality traits (P<0.001), mainly the egg weight, shell weight, shell thickness, eggshell-breaking strength, and eggshell redness (a*) and yellowness (b*), besides the metabolic profile of both egg yolk and albumen. Considering the interaction diet * age of hens, only a few significant effects occurred on egg quality attributes and FA profile. In conclusion, a supplementation with live BSFL up to 30% of DFI may be safely used in laying hen feeding without impairing egg quality.

Dietary phytosterols induce infertility in female mice via epigenomic modulations

Dietary modifications to overcome infertility have attracted attention; however, scientifically substantiated information on specific dietary components affecting fertility and their mechanisms is limited. Herein, we investigated diet-induced, reversible infertility in female mice lacking the heterodimer of ATP-binding cassette transporters G5 and G8 (ABCG5/G8), which functions as a lipid exporter in the intestine. We found that dietary phytosterols, especially β-sitosterol and brassicasterol, which are substrates of ABCG5/G8, have potent but reversible reproductive toxicities in mice. Mechanistically, these phytosterols inhibited ovarian folliculogenesis and reduced egg quality by enhancing polycomb repressive complex 2-mediated histone H3 trimethylation at lysine 27 in the ovary. Clinical analyses showed that serum phytosterol levels were significantly and negatively correlated with the blastocyst development rate of fertilized eggs in women undergoing in vitro fertilization, suggesting that phytosterols affect egg quality in both humans and mice. Thus, avoiding excessive intake of certain phytosterols would be beneficial for female reproductive health.

Effect of Radio Frequency Energy for Intervention Processing on the Quality of Intact Eggs.

During conventional pasteurization, eggs are submerged for 60 min at 56.7 °C, a lengthy and costly process that affects egg quality. Radio frequency (RF), a means to pasteurize eggs without affecting quality, is a novel option based on fast volumetric heating; however, there is scarce information about the quality of such treated food. This research consisted in a comprehensive quality study on eggs treated with RF. The RF system was operated at 40.68 MHz, 40 W and 16 W (8 min total), and 42 rpm. The quality assessment included the determination of Haugh unit, yolk index, compression strength, albumen turbidity, albumen and yolk pH, and yolk color. Additional analyses were conducted to quantify the mineral composition of the eggshell (40.68 MHz, 40 W, 42 rpm, 5.5, 8.5, and 10 min); these samples were observed by SEM. The results showed that RF did not significantly (p > 0.05) change any quality parameters. The mineral composition remained constant in processed eggs. The SEM images of RF-treated eggs showed some smooth spots; however, these areas could exist due to the high variability of the eggshells. RF is an option to process intact eggs, maintaining their fresh quality and keeping the integrity of the eggshell to ensure the food safety of the internal egg components.

Impact of High-Dose Supplemental Paprika Extract Feeding on Egg Storage and Biochemical Parameters in Laying Hens.

This study aimed to evaluate the effects of paprika extract supplementation on egg storage and blood biochemical parameters in 63-week-old Rhode Island Red (RIR) and Silky Fowl (SF) hens. The hens were divided into three groups: a control group with a basal diet and two groups receiving the basal diet with paprika extract. The trial lasted 28 days, with egg quality (yolk color and albumen pH) assessed after storing eggs at 25 °C for 21 days. A total of 144 eggs were used in 42 treatments (two breeds, three diets, and seven storage periods) with three eggs examined each (four eggs were used on day 0 and five eggs on day 21). Additionally, the yolk carotenoid content, yolk color, and pH of eggs stored at 4 °C and 25 °C were compared. Results showed that yolk color fan score (YCFS) decreased with storage, and SF had a higher albumen pH than RIR, with both breeds exhibiting an increase in pH over time. HDL cholesterol (HDL-C) levels and the HDL-C to total cholesterol ratio were significantly influenced by breed, diet, and their interaction. The HDL-C level in SF was affected linearly and quadratically by diet, while no such trend was observed in RIR. The study concluded that paprika extract affects egg quality and blood lipid profiles differently in different breeds, highlighting breed-specific responses to dietary supplementation.

The Influence of Dietary Supplementation with Dried Olive Pulp on Gut Microbiota, Production Performance, Egg Quality Traits, and Health of Laying Hens.

This study examines the dietary effect of dried olive pulp (OP) on the overall performance, egg quality, health, and gut microbiota of laying hens during a 36-week trial. A total of 180 Isa Brown layers, aged 23 weeks, were assigned to 15-floor pens and divided into three feeding groups (CON, OP4, and OP6) based on the dietary level of OP. Egg quality and biochemical parameters were assessed in 39- and 59-week-old hens. Fecal samples were collected for microbiota analysis. Data were analyzed with an Analysis of Variance. The percentage of broken eggshells was found to be 15-34% lower in the OP groups compared to the CON groups. At 59 weeks of age, a significant reduction in shell thickness was observed in the CON eggs compared to the OP eggs (p < 0.05). At 39 weeks of age, OP6 eggs had the darkest yolk color of all groups (p < 0.05). Fecal microbial diversity was affected only by hens' age. However, an enrichment in bacterial species belonging to the genera Megasphaera and Megamonas was found in the OP groups at 59 weeks of age. Our results demonstrate that OP feeding beneficially affects egg quality and promotes the proliferation of bacteria involved in the degradation of complex plant compounds, potentially contributing to the overall health of the gut microbiota.

FACTORS AFFECTING EGG QUALITY AND FUNCTIONAL PROPERTIES

Egg external and internal quality attributes are of great importance for egg industry worldwide. The current bibliographical analysis and review covers egg composition and factors affecting egg quality. Egg quality is generally measured as its shell quality and internal quality. The analysis of egg shell quality includes egg shell color (CIE L*, a*, b*), size, egg specific gravity, shell deformation, shell breaking strength, shell weight, shape index, shell percentage, shell thickness, and shell ultrastructure. The egg internal quality is measured as albumen quality, Haugh Unit, yolk color, the integrity of the perivitelline membrane, chemical composition of egg components and the egg functional properties. Factors that influence egg shell quality and egg internal quality are reviewed herein. Egg external quality can be affected by the strain and age of the avian resource, moult, feeding, feed quality, stress, disease, rearing system, or addition of food residues of egg producer to the diets. The egg internal quality depends on storage, avian species, strain, age, moult, nutritional condition, production system, disease and agro climatic conditions. A better knowledge and control of this range of factors that affect egg external and internal quality is very important and critical for good quality eggs production and egg product quality.

Genotype and dietary supplementation of ginger (Zingibar officinale) rhizome powder affect egg quality traits of layer chickens

This study evaluated the effects of ginger (Z. officinale) rhizome powder on egg qualities of aged commercial and native hens using 160 Shaver Brown (SB) and Nigerian heavy ecotype native hens (HEN). Experimental groups per genotype were control group or basal diet group, and ginger rhizome powder supplemented group (20 g/kg, ginger group). For each genotype, forty (40) hens were assigned to the control group and 120 hens to the ginger group. Each experimental group had four (4) replicates containing 10 hens each for the control groups, and 30 hens each for the ginger groups. The hens were housed individually in laying cages and fed the experimental diets at 125 g/bird/day. Water was given ad libitum and photoperiod was 12 h light and darkness. 80 eggs from SB and 40 eggs from HEN control groups, and 80 eggs/genotype from the ginger groups were used to evaluate egg qualities while 10 shell samples were used to evaluate shell mineral contents for each group. In addition, within genotypes, eggs belonging to the ginger groups were grouped into egg weight and egg shape index grades and assessed for egg qualities. SB eggs had significantly (p ≤ 0.05) higher weight (EW), length (EL), diameter (ED), surface area (ESA), volume (EV), and shape index (ESI); yolk, albumen, and shell weights (YW, AW and SW); albumen height, diameter, and ratio (AH, AD, and AR); shell volume (SV), compression fracture force (SCFF), and calcium content but lower egg specific gravity (ESG), yolk ratio (YR), yolk/albumen ratio (Y/A ratio), shell Zinc, and Phosphorus contents compared to HEN eggs. Ginger groups had higher EW, EL, ESA, EV, YW, YD, YR, AH, AI, Y/A ratio, and shell Zn but lower ESG, YH and YI compared to control groups. SB-ginger group had highest (p ≤ 0.000) AD while HEN-ginger group had highest (p ≤ 0.05) shell Zinc, and Phosphorus contents. EW grades differed significantly in EW, ESA, ESG, ESI and SCFF in the two genotypes while ESI grades differed significantly in ESI and Y/A ratio in SB but in ESI, YI and Haugh unit in HEN. In conclusion, genotype, diet, genotype x diet, EW and ESI grades influenced egg quality traits. These factors are important for egg quality evaluation and genetic improvement.

Effects of β-Mannanase Supplementation and Soyhull Inclusion on Production Performance, Economics, Egg Quality, Blood Biochemicals, Nutrient Digestibility, and Intestinal Morphology in Golden Brown Hens (RIR × Fayoumi) during Late Peak Production.

This study investigated the effects of the β-mannanase enzyme and soyhulls on production performance, economics, egg quality, hematology and serum biochemistry, nutrient digestibility, gut morphology, digesta viscosity, and excreta consistency in laying hens during the late peak production phase (37 to 40 weeks of age). Golden brown hens (RIR × Fayoumi; n = 200) were fed a control diet (no soyhulls or enzymes) and diets containing four combinations, i.e., 3% soyhulls with 20 mg/kg β-mannanase (D1), 3% soyhulls with 30 mg/kg β-mannanase (D2), 9% soyhulls with 20 mg/kg β-mannanase (D3), and 9% soyhulls with 30 mg/kg β-mannanase (D4), for four weeks in four replicates of 10 birds each. Overall, a significantly higher (p < 0.05) feed intake, weight gain, feed conversion ratio, and water intake were calculated in the D2 group as compared to the control and remaining combinations of soyhulls and β-mannanase. No mortality was recorded during the entire experiment. Economically, the D1 and D2 groups showed the best results as compared to the D3 and D4 groups. Egg quality parameters like egg weight, shell weight and shell thickness, yolk weight, albumen weight and height, and the Haugh unit remained unchanged (p > 0.05). Similarly, the D2 group showed significantly lower total cholesterol, LDL, and VLDL levels and enhanced gut morphology with greater villus width, height, crypt depth, and surface area across intestinal segments. Crude protein (CP), crude fiber (CF), crude fat, and ash digestibility were higher (p < 0.05) in the D1 and D2 groups compared to the control. Digesta viscosity, excreta consistency, and other egg quality parameters remained unaffected. In conclusion, the dietary inclusion of a combination of 3% soyhulls and 30 mg/kg β-mannanase may have potential benefits for laying hens by improving some production performance and egg quality indicators and economics, lowering blood cholesterol, LDL, and VLDL levels, enhancing nutrient digestibility, and improving gut morphology without affecting egg quality.

Yacon (Smallanthus sonchifolius) root extracts affect laying performance, egg quality, serum biochemical parameters and intestinal microbiota in hens.

The objective of this study was to investigate the influence of yacon root extracts (YREs) on productive performance and health of laying hens. Six hundred 30-week-old Xiaoshan Chicken layers were divided into 5 groups, control group, antibiotic positive control group, and 3 YREs treatment groups. In a 9-wk feeding experiment, at the end of wk 3, 6, and 9, twenty eggs were collected from each replicate to measure egg qualities. At the end of wk 9, three hen serum samples, and 5 hen cecal content samples were collected from each replicate. Compared to the control group, 0.8%, 1.6%, and 2.4% YREs treatments could increase hens' daily feed intake, and YREs supplementation affected daily feed intake in linear manner. YREs did not change egg size, but 0.8% and 2.4% YREs changed egg shape by decreasing the egg shape index and sphericity, and 0.8% YREs tended to improve the eggshell breaking strength. Diet supplemented with 1.6% YREs might decrease yolk color grade but optimize the pH of thick egg white in fresh egg; moreover, 1.6% and 2.4% YREs might be helpful for eggs to inhibit water loss during storage, and YREs supplementation affected water loss rate in linear manner. 2.4% YREs could decrease the serum lactate dehydrogenases (LDH) level, and YREs supplemental levels linearly affected serum LDH content. Finally, YREs could enrich the diversity of intestinal microbiota of hens fed with 0.8% and be beneficial for the relative abundance of phylum Bacteroidota and Halobacterota; 2.4% YREs might increase the abundance of phylum Actinobacteriota and genus Bifidobacterium, while decrease genus Bacteroides; YREs supplemental levels affected the abundance of phylum Actinobacteriota, and genera Bifidobacterium and Bacteroides in linear manner. Dietary supplementation with YREs could affect egg quality, protect the health of organs and exhibit prebiotic activity.

Deoxynivalenol and T-2 toxin cause liver damage and egg quality degradation through endoplasmic reticulum stress in summer laying hens.

The present study aimed to find whether low doses of mixed mycotoxins would affect egg quality in laying hens, and to explore the oxidative stress induced liver damage through endoplasmic reticulum during summer stress. A total of 96 Jinghong laying hens, 36 wks of age, were divided into four treatments, with eight repetitions per treatment and three hens per repetition. All the hens were raised in summer (average temperature: 31.3 ± 0.5℃; average humidity: 85.5 ± 0.2%) for 28d. One treatment was fed a basal diet as control (CON), and the other three treatments were fed the same diets containing 3.0mg/kg deoxynivalenol (DON), 0.5mg/kg T-2 toxin (T-2), and 1.5mg/kg DON + 0.25mg/kg T-2 toxin (Mix). Albumen height and Haugh unit were decreased (P < 0.05) in the Mix group on day 14 and 28. The activity of total antioxidant capacity, glutathione peroxidase, catalase, and superoxide dismutase were decreased (P < 0.05) in the DON, T-2, and Mix groups. The alkaline phosphatase level in DON, T-2, and Mix groups was significantly increased (P < 0.05). The level of interleukin-1β, interferon-γ, and tumor necrosis factor-α in the Mix group were higher (P < 0.05) than CON, DON, and T-2 groups. Mix group upregulated the mRNA expressions of protein kinase RNA-like ER kinase, activating transcription factor4, IL-1β, nuclear factor-κ-gene binding, and nuclear respiratory factor 2 in the liver (P < 0.05). The results showed that low doses of DON and T-2 toxin could cause oxidative stress in the liver, but DON and T-2 toxin have a cumulative effect on virulence, which can reduce egg quality and cause endoplasmic reticulum stress in the liver.

Calcareous seaweed in the diet of growing Japanese quail

Abstract In this way, the present study assessed the replacement of inorganic calcium sources by organic sources in the diet of growing Japanese quails. The study analyzed 300 Japanese quails distributed in a completely randomized design with 3 treatments (control, 0% inclusion; 0.50% inclusion of calcareous seaweed 1; 0.50% inclusion of calcareous seaweed 2, with both inclusions concerning the replacement of calcitic limestone in the diet). Calcium sources did not differ in terms of either the production performance of birds in the growth phase or at the beginning of laying or in terms of yield, weight, organ size or bone quality. The biochemical blood profile did not change, except for the AST index. The replacement treatment affected egg quality, colorimetric fan color, albumen and yolk height, Haugh unit, and the yolk index. Including 0.50% calcareous seaweed as a replacement for calcitic limestone in the diet of quail does not harm production performance, animal health, organ yield, or bone quality in the growth phase. This diet guarantees satisfactory performance and high-quality eggs in the early laying phase.

Dietary probiotic Lacticaseibacillus paracasei NSMJ56 modulates gut immunity and microbiota in laying hens

This study was performed to investigate supplementary effects of probiotic Lacticaseibacillus paracasei NSMJ56 strain on laying performance, egg quality, intestinal histology, antioxidant status, gut immunity and microbiota in laying hens. A total of ninety-six 21-wk-old Hy-Line Brown laying hens were randomly subjected to one of 2 dietary treatments: a control group fed a non-supplemented diet, or a probiotic group fed with a diet supplemented with 1 g of Lacticaseibacillus paracasei NSMJ56 (5 × 108 CFU/kg of diet). The trial lasted for 4 wk. Egg weight was increased (P < 0.05) in laying hens fed probiotic-fed diet compared with the control group. Dietary probiotics did not affect egg quality except for Haugh unit, which was improved (P < 0.05) in the probiotic-fed group. Neither jejunal histology nor cecal short-chain fatty acids were affected by dietary treatments. Dietary probiotics increased the activity of catalase compared with the control group. Flow cytometry analysis revealed that dietary probiotics elevated the CD4+ T cells, but not CD8+ T cells, in jejunal lamina propria. Based on the LEfSe analysis at the phylum and genus levels, Erysipelotrichales, Erysipelotrichia, Flintibater, Dielma, Hespellia, Coprobacter, Roseburia, Anaerotignum, and Coprococcus were enriched in the probiotic group compared with the control group. Taken together, our study showed that dietary probiotics could be used to improve some parameters associated with egg freshness and antioxidant capacity, and to partially alter T cell population and microbial community in laying hens.

Predicting Infertility: How Genetic Variants in Oocyte Spindle Genes Affect Egg Quality.

Successful reproduction relies on the union of a single chromosomally normal egg and sperm. Chromosomally normal eggs develop from precursor cells, called oocytes, that have undergone accurate chromosome segregation. The process of chromosome segregation is governed by the oocyte spindle, a unique cytoskeletal machine that splits chromatin content of the meiotically dividing oocyte. The oocyte spindle develops and functions in an idiosyncratic process, which is vulnerable to genetic variation in spindle-associated proteins. Human genetic variants in several spindle-associated proteins are associated with poor clinical fertility outcomes, suggesting that heritable etiologies for oocyte dysfunction leading to infertility exist and that the spindle is a crux for female fertility. This chapter examines the mammalian oocyte spindle through the lens of human genetic variation, covering the genes TUBB8, TACC3, CEP120, AURKA, AURKC, AURKB, BUB1B, and CDC20. Specifically, it explores how patient-identified variants perturb spindle development and function, and it links these molecular changes in the oocyte to their cognate clinical consequences, such as oocyte maturation arrest, elevated egg aneuploidy, primary ovarian insufficiency, and recurrent pregnancy loss. This discussion demonstrates that small genetic errors in oocyte meiosis can result in remarkably far-ranging embryonic consequences, and thus reveals the importance of the oocyte's fine machinery in sustaining life.

Egg Quality, Sensory Attributes, and Protein Metabolites of Laying Hens Fed Whole Flaxseed, Fish Oil, and Different Sources of Trace Elements.

This study evaluated the effects of whole flaxseed (WFS), fish oil (FO), and different sources of Se, Zn, and Fe (inorganic, organic, and nano-source) on egg production, quality, sensory attributes, and serum protein metabolites in laying hens. A total of 144 hens were divided into six groups with six replicates of four hens each. Hens were fed six diets as follows: 1) control diet; 2) 7.5%WFS+1.5%FO; 3) 7.5%WFS+1.5%FO+175 mg/kg vitamin E (VE); 4) 7.5%WFS+1.5%FO+175 mg/kg VE + inorganic sources of Se, Zn, and Fe (ISeZnFe); 5) 7.5%WFS+1.5%FO+175 mg/kg VE + organic sources of Se, Zn, and Fe (OSeZnFe); 6) 7.5%WFS+1.5%FO+175 mg/kg VE + nano-source of Se, Zn, and Fe (NSeZnFe) from 40-50 weeks of age. Laying hens fed 7.5% WFS, 1.5% FO, and different sources of trace elements in their diets had no negative effects on laying rate, egg weight, egg mass, feed intake, feed conversion ratio, body weight change, or survival rate compared to that of hens fed the control diet. Dietary treatments did not negatively affect the external and internal egg characteristics or egg sensory attributes. Feeding 7.5%WFS+1.5%FO+VE+ISeZnFe positively influenced yolk color in fresh eggs. Dietary treatments had a significant impact on egg nutritional composition, with the highest levels of macronutrients found in eggs from hens fed the 7.5%WFS+1.5%FO+VE+NSeZnFe treatment. The highest plasma globulin concentrations were observed in hens fed organic and nano-source trace elements. The same diets reduced plasma uric acid levels. Based on these findings, the inclusion of organic or nano-source trace minerals in diets containing WFS and FO positively affected egg quality and hen protein metabolites.

Effects of Astaxanthin Preparation Form on the Efficiency of Egg Yolk Pigmentation in Laying Hens.

This study investigated the effects of the preparation form of astaxanthin on egg yolk pigmentation and egg quality in laying hens. The following four astaxanthin sources were prepared in this study: (1) dried cell powder of Paracoccus carotinifaciens (Panaferd-AX), (2) fine cell powder of P. carotinifaciens (Panaferd-P), (3) astaxanthin oil suspension, and (4) water-soluble astaxanthin powder. These astaxanthin preparations were added to the basal diet at a final concentration of 2 mg/kg and fed to White Leghorn laying hens for 14 days. Although the administration of these astaxanthin preparations did not largely affect egg quality (i.e., egg weight, yolk weight, albumen height, and Haugh unit), feeding significantly improved astaxanthin concentration and yolk color fan score. When water-soluble astaxanthin powder was fed, the yolk astaxanthin concentration and color fan score were most improved, followed by Panaferd-P. These results indicated that astaxanthin pulverization and water solubilization significantly improved its bioavailability in laying hens. Furthermore, although diets rich in (all-E)-astaxanthin were fed to the hens, approximately 30% of astaxanthin was present as the Z-isomers in the egg yolk. These findings may contribute to improving not only the egg quality but the nutritional value of hen eggs.

MACHINE LEARNING SMART PACKAGING PENGIRIMAN TELUR AYAM BERBASIS INTERNET oF THINGS (IoT) MENGGUNAKAN ALGORITMA C.45 DENGAN PLATFORM THINGSPEAK

In the era of Industry 4.0, the integration of Machine Learning and the Internet of Things (IoT) plays a crucial role in enhancing the efficiency and safety of logistics processes. This research aims to develop a Smart Packaging system for the shipment of chicken eggs utilizing Machine Learning with the C.45 algorithm and IoT-based on the ThingSpeak platform. The system integrates Node-MCU (ESP8266) as the central processing unit, the DHT11 sensor to monitor temperature and humidity within the packaging, the Vibration Sensor SW-420 to detect potential damage to eggs during shipment, and the Unblock Neo6m-V2 GPS Module for real-time location tracking.

Sensor data is collected and transmitted to the ThingSpeak platform through the Wi-Fi connection provided by Node-MCU. The C.45 algorithm is applied to analyze the data, provide predictions regarding egg conditions, and make decisions for further actions during the shipping process. Experiments were conducted to evaluate the system's accuracy using RapidMiner software. The results indicate that the system is capable of predicting egg conditions with a high level of accuracy, enabling responsive actions to situations that may affect egg quality during shipment. The implementation of Machine Learning and IoT technologies in this chicken-egg shipping system is expected to enhance the quality of delivered products, optimize logistical processes, and provide an intelligent solution to ensure the sustainability of the food product supply chain.

Impact of broiler breeder hens’ age and egg storage on egg quality, embryonic development, and hatching traits of FUNAAB-alpha chickens

This study aimed to determine the impact of the age of breeder hens and egg storage on egg quality, embryonic development, hatching events and chick quality in FUNAAB-alpha chickens. The study involved the use of 500 hatching eggs each collected from 32-wk and 60-wk-old of FUNAAB-alpha broiler breeder hens at the Animal Breeding and Genetic Unit of the Federal University of Agriculture, Abeokuta, Nigeria and subjected to 5 storage periods (0, 3, 7, 11, and 15 d). The quality traits of the eggs were recorded and incubated using the conventional protocol. Data were collected on the internal and external egg characteristics, embryonic development, hatching events, and chick quality. The data collected were laid out in 2 by 5 factorial design. The results showed that eggs from 32-wk-old breeder hens had higher albumen height and Haugh unit (HU) value than those from 60-wk-old breeders. The albumen height and HU decreased progressively with storage length in the 2 age groups. Extended storage duration linearly increased (P < 0.01) egg weight loss and decreased (P < 0.01) yolk height. The eggs from both breeder ages had increasing blastodermal diameters at oviposition up until d 11 of storage but decreased on d 15 of storage in eggs from 32 wk breeders. Eggs of 32-wk-old FUNAAB-alpha breeder hens had larger diameters at oviposition compared with 60-wk-old breeders. The chicks from 60-wk breeder had late internal pipping (469.06 h), early external pipping (474.46 h) and a shorter time lag between both pips (9.00 h) compared to chicks from 32 wk breeder. The highest fertility was recorded in eggs stored for 3 d (80.7% and 79.6%), while the lowest fertility was in eggs stored for 15 d (53.4% and 47.7%) in both 32-wk and 60-wk-old breeders, respectively. Chicks from young breeder hens stored for 3 d had better quality scores (100%) compared to 0, 7, 11, and 15-d storage duration and in 60-wk-old breeders across all storage duration. It was concluded that both egg storage duration and age of breeder affected egg quality, hatching events and hatchling quality of FUNAAB-alpha chickens and the interaction effects of both factors was recorded for some of these traits. However, extended storage beyond 7 d had a larger negative impact on egg quality and hatchability of eggs from an old breeder (60 wk) than on eggs of a young breeder (32 wk).

Pengaruh Suhu Dan Lama Penyimpanan Pada Kualitas Fisik Dan Mikrobiologis Telur Ayam Ras

Eggs are one of the products from animals that are most widely used by the community, eggs have a fairly complete nutritional content and also the price is relatively cheap. Egg quality can decrease. Temperature and length of storage of eggs can affect egg quality. The purpose of this study was to determine the effect of different temperatures and storage periods on and determine the optimal egg quality and microbiology of eggs laying hens at different temperatures and storage periods. This research was conducted by using a sample of eggs laying hens aged 0 days and getting treatment by being stored in different storage conditions. Parameters measured to determine egg quality were organoleptic, egg white index, egg yolk index, Haugh Unit, pH and microbiological quality. This study was a completely randomized design (CRD), which consisted of six treatments with three trials. Based on the tests that have been carried out, the Haugh Unit, Egg White Index, Egg Yolk Index, Organoleptic and Total Plate Count values of eggs stored at room temperature and 4 °C have an influence on egg quality. purebred eggs laying hens stored at 4 °C have better quality in terms of shelf life compared to eggs stored at room temperature.

Orychophragmus violaceus and/or chicory forage affects performance, egg quality, sensory evaluation and antioxidative properties in native laying hens

Orychophragmus violaceus (OV) and chicory (Cichorium intybus L., CC) can be used as fresh or dry forage for animals. To determine whether OV and/or CC have beneficial effects on performance and egg quality, a total of 1212 28-wk-old Beijing You Chicken (BYC) laying hens with similar performance were randomly allocated to 4 groups with 3 replicate pens per group, and 101 birds per pen. The birds were fed a basal diet (control), the basal diet + OV (3.507 kg/d/pen), the basal diet + CC (2.525 kg/d/pen), and the basal diet + OV + CC (OVC, 1.7535 kg/d/pen OV + 1.2625 kg/d/pen CC) for 3 wks after one wk of adaptation. The results showed that egg-laying rate was not affected by OV, CC and OVC (p > 0.05), but weekly average egg mass was significantly increased by OV and CC (p < 0.05). The feed egg ratio in the CC group (2.82) was significantly lower than that in the other three groups (p < 0.05). The eggshell thickness (EST), albumen height (AH) and Haugh unit (HU) were decreased by OV and CC (p < 0.05); while yolk color (YC) was increased in the CC and OVC groups (p < 0.05). Egg grade was decreased by OV (p < 0.05). Sensory evaluation showed that there was a trend for increased YC in OV, CC and OVC (p = 0.089). Serum total protein was significantly lower in OV group than those in the control and CC group (p < 0.05); serum albumin content was significantly decreased in OV, CC and OVC groups (p = 0.006). Serum glutathione peroxidase activity in CC and OVC groups was significantly higher than that in the control group (p < 0.05). In conclusion, the present study suggests that CC had a better effect on the performance of the native laying hens than OV. The OV and CC affected egg quality, while YC was increased in CC and OVC groups. The OVC improved YC and serum antioxidative properties of native laying hens without affecting the performance.
