Also, evaluate the impact of these treatments on productive and physiological performance of Inshas laying hens. A 3x3 factorial design experiment was performed including three stocking densities (6, 9 or 12 birds/m<sup>2</sup>) with three dietary levels of licorice (0, 0.5 and 1.0 %). A total number of 216 hens of Inshas local strain at 44 weeks of age were randomly distributed into 9 treatment groups with two replicates and housed during the experimental period 44 -56 weeks of age in floor pens with dimensions of 2 × 2 m. The results indicated that increasing stock density to 12 birds/m<sup>2</sup> caused a significant reduction in most of productive performance, fertility and hatchability percentages and blood parameters. Meanwhile, reducing stock density to 6 and 9 birds /m<sup>2</sup> participated in avoiding the negative effect. However, the best results for the previous parameters were exhibited by stocking density at 9 birds / m<sup>2</sup>.<br /> Regardless stock density, addition of licorice significantly increased egg production, egg number, egg weight, egg mass and improved feed conversion but feed consumption was not affected. Also, there was significant improvement in fertility and hatchability percentages, egg quality traits (egg shell thickness, Haugh unit score and egg yolk color) and most of blood parameters due to licorice supplementation. The best results were obtained by adding licorice at level of 0.5 %.<br /> With regard to the interaction between stock density and licorice addition. It could be observed that, the highest egg production, egg weight, economic efficiency, the best feed conversion and the lowest feed consumption were recorded for hens received 0.5% licorice in their diet with stocking density of 9 birds / m<sup>2</sup>. In addition, the best blood parameter values and the lowest plasma total lipids and LDL concentrations were achieved by the same treatment (0.5% licorice with stocking density of 9 birds/m<sup>2</sup>).<br /> <strong>In conclusion</strong>, from this study, it can be concluded that adding 0.5% licorice to laying hen diets with stocking density to 9 birds /m<sup>2</sup> was more efficient in improving the performance and economic efficiency increasing of Inshas laying hens.https://epsj.journals.ekb.eg/article_225211_7c311b148c10687c2c5491ed88e3d8fa.pdfThe Egyptian Poultry Science AssociationEgyptian Poultry Science Journal1110-562342120220301NUTRITIONAL AND HEALTH ASPECTS OF EARTHWORMS (EISENIA FOETIDA) SUPPLMENTATION IN POULTRY DIETS: REVIEW ARTICLE395722521410.21608/epsj.2022.225214ENAbdel-Azeem Abdel-Azeem1Dep. of Anim.

Res. Instit., Agric. Res. Cent., Ministry of Agric., EgyptJournal Article20220126In recent years and globally, the poultry industry has become of great importance in the production of animal protein, with the increase in per capita consumption of meat and eggs around the world. It is noteworthy that the cost of feed production represents 60-70% of the total poultry production, where protein is the most expensive component. Protein sources are known to be of either animal or vegetable origin, with animal sources having a more balanced amino acid profile. But due to the limitations on the availability of traditional feeds for poultry as well as the remarkable development in the development of new genetic strains, all this has led to a change in nutritional needs. So researchers began looking for new and alternative protein sources to reduce feed costs, such as using the <em>Eisenia foetida</em> earthworm, which is a new and safe source of animal protein. But until now, the possibility of using Eisenia foetida as one of the new and safe sources of poultry feed in Egypt has not been studied. On the other hand, <em>Eisenia foetida</em> can be used for other purposes, such as the technique of producing vermicompost, which is one of the new technologies for the safe treatment of non-toxic organic waste using earthworms, because there is an urgent need to recycle poultry waste in a safe and environmentally friendly manner, and this can be applied through the use of earthworms. Therefore, the aim of this article is to shed light on the use of <em>Eisenia foetida</em> as one of the new partial alternative sources of protein that can be used in poultry rations to reduce production cost without affecting production performance, health aspects or the quality of its products.<br /> https://epsj.journals.ekb.eg/article_225214_667c2e473583031e1a842e0978412b46.pdfThe Egyptian Poultry Science AssociationEgyptian Poultry Science Journal1110-562342120220301SOME PRODUCTIVE AND PHYSIOLOGICAL RESPONSES OF GROWING JAPANESE QUAILS TO SUDANESE PROPOLIS ADDITION597522871210.21608/epsj.2022.228712ENAmira EldlebshanyPoultry Breeding

Sudan.Journal Article20220105The current study was performed aiming to investigate the untraditional natural additives such as different levels of Sudanese propolis as prospective alternatives through studying their effect on productive performance, physiological parameters and oxidative status of Japanese quails. A total number of 480 unsexed Japanese quails at 7days of age were randomly distributed for four equal treatments; every treatment contains120 birds for each treatment. <strong> </strong>Four equal treatments were received four dietary treatments depending on addition of Propolis levels from 7 days to 42 days of quails age as follows: T1: Control (basal diet without Propolis addition). T2: basal diet + 250 mg Propolis /kg diet. T3: basal diet + 500 mg Propolis /kg diet. T4: basal diet + 750 mg Propolis /kg diet.Results showed that body weight at 42 days was heavier significantly (p=0.0020) with 750 and 500 mg propolis addition treatments than control and 250 mg treatments. The same trend found in body weight gain during growing period of quails, which increased significantly (p=0.0035) by 5 and 8% with 500 and 750 mg/kg diet Propolis addition than control, respectively. Moreover, feed conversion ratio was improved significantly (p=0.0239) by 3, 7.5 and 11% compared to control with the three levels of Propolis, respectively. Red blood cells, hemoglobin and hematocrit values were significantly increased with the three levels of Propolis compared to control. Total lipids, cholesterol, triglycerides and LDL were significantly decreased with the three levels of Propolis compared to control. While, HDL was significantly increased with the three levels of Propolis compared to control. Furthermore, IgM, lymphocytes, globulin and total antioxidant capacity were significantly increased with the three levels of Propolis compared to control. From these results we can concluded that, addition of Propolis caused significant improvements in quails’ productive performance and anti-oxidative status.https://epsj.journals.ekb.eg/article_228712_da1bf02b9321b75b4017866f1fd83140.pdfThe Egyptian Poultry Science AssociationEgyptian Poultry Science Journal1110-562342120220301EFFECTIVENESS OF CERTAIN NATURAL FEED SUPPLEMENTS ON PRODUCTIVE PERFORMANCE, NUTRIENTS DIGESTION COEFFCIENT, CARCASS CHARACTERISTICS, AND SOME BLOOD PARAMETERS OF BROILER CHICKS SHORT TITLE: EFFECT OF NATURAL FEED ADDITIVES ON BROILER779322522410.21608/epsj.2022.225224ENMaha AhmedAbd El LatifAnimal and poultry production department, faculty of agriculture, minia university, el minia0000-0002-4557-9816Journal Article20220118This experiment was made to evaluate the effect of adding leaves powder of (<em>Moringa</em> <em>olifera</em>), fenugreek seeds (<em>Trigonella foenum</em>), dry yeast (<em>Saccharomyces cerevisiae</em>) and mixture (fenugreek + Moringa + yeast) on growth, carcass traits, nutrients digestibility, some blood constituents and economic efficiency of Sasso broiler chicks.

Total of 40 birds at 33 weeks of age (20 male and 20 female) were used. The hematological profile included hemoglobin (Hb), red blood cells (RBCs), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and white blood cells (WBCs), whereas the biochemical parameters include total protein, globulin, cholesterol, uric acid “etc.” Significantly (p≤0.05) higher, RBC, PCV, and WBC values were recorded in males than females. Total protein, globulin, cholesterol, triglycerides, calcium, uric acid, alkaline phosphatase were significantly (p < 0.05) higher in females. The rest of the parameters were not significantly different between the sexes. Interestingly, almost all investigated hematological and blood chemical parameters in these chickens were within range of the recorded reference values of healthy birds. This study concluded a significant effect of sex on various physiological characteristics of the Sliver Sabahia chicken strain. Also, this paper exclusively provided reference values of hematological and blood chemistry for this strain, which help in the breeding programs to produce the commercial egg type strain.https://epsj.journals.ekb.eg/article_229633_56ee0eb1d653f6ba123331e69e65dc60.pdfThe Egyptian Poultry Science AssociationEgyptian Poultry Science Journal1110-562342120220301INFLUENCE OF DIETARY ENERGY AND PROTEIN THROUGHOUT GROWTH PHASE ON SUBSEQUENTLY EGG PRODUCTION AND HATCHING FEATURES OF SUDANI DUCKS12113622962810.21608/epsj.2022.229628ENAwad LotfyAwadanimal production reaserch instituteAymen IbrahimGhonimAnimal production research instituteKout Elkloob ElsyedMostafaAnim.

The dietary ME levels in the starter period were 2600 (ME1), 2800 (ME2) and 3000 (ME3) kcal /kg, each contained crude protein level of 18 (CP1), 20 (CP2) and 22 (CP3) % from hatch up to 8 weeks of age , then followed by grower diets contained 2550, 2650, and 2750 kcal of ME/kg, each contained of 12, 14 and 16 % CP , respectively, from 9 up to 20 wks of age, after that one layer diet was provided to all experimental categories at 21 up to 41 wks.<br /> Results showed that ducks body weight (BW) at 20 wks-old was (P < 0.01) elevated by rising ME in the diet through rearing phase, while higher BW was occurred by feeding medium CP level. Moreover, feed conversion ratio was (P < 0.01) improved by elevating both ME and CP level in diet from hatch up to 20 wks-old. Ducks age at 1<sup>st</sup> egg, 25.0% and peak of egg production was (P < 0.05) decreased as a result of feeding diet contained ME3 during rearing period, while it was decreased by feeding both CP2 and CP3 than those fed CP1in the diet. Subsequent laying measurements (egg number and mass, feed conversion) were (P < 0.01) enhanced by ME3 compared with ME2 and ME1 groups, while these improvements were occurred with CP2 only throughout the tested period (25-41 wks-old). The best values of laying parameters were occurred with ME3 and CP2 interaction. All studied hatching features were (P > 0.05) influenced by varied CP levels and the interaction between ME and CP, while different ME in diet had significant effect on fertility and embryonic mortality percentages. The results cleared that using high ME (3000 kcal/kg) with medium CP (20%) in starter diet followed by ME (2750 kcal/kg) with CP (14%) in grower diet throughout rearing phase of Sudani ducks, which should be followed by a layer diet containing 2850 Kcal, ME / kg with 17 % CP could be decreased the ducks age at sexual maturity (at first egg laid), enhanced the subsequent egg production performance and improved hatching traits.https://epsj.journals.ekb.eg/article_229628_5c6596fc34580b46f9834915018e9572.pdf
