: This study was carried out to evaluate the effects of dietary saponin supplementation and essential oil (thymol and carvacrol) on growth performance and some biochemical parameters of broiler chickens. Two hundred and fourty one-day-old chicks (Ross 308), which was randomly divided into 8 treatment groups each with three replicates of 10 birds. The first treatment (T1) was fed a diet without saponin while, saponin 10 ppm (T2), 20 ppm (T3) and 40 ppm (T4), however birds in group 5 (T5) fed diet without saponin and in drink water with 50 ppm essential oil, saponin 10 % with 50 ppm EO (T6), 20 ppm with 50 EO (T7) and 40 ppm with 50 EO (T8). Results obtained revealed that chicks fed basal diet with saponin had significantly (P < 0.05) better body weight, weight gain and feed conversion ratio, while feed intake was reduced comparison with control treatment. Chicks that received a diet supplemented with saponin at 20 or 40 ppm with 50 ppm EO significantly (P<0.05) improved growth performance compared with the other treatments. Supplementation of essential oils and saponin at levels of 40 and 20 ppm, respectively significantly increased Serum protein fractions (total protein, albumin and globulin). Significant reductions in serum total cholesterol and triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol were detected in the group that fed diet with 20 and 40 ppm diet saponin plus EO 50 ppm compared with other diets. Consequently, these findings suggest that phytogenic feed additives, particularly essential oils combined with saponin, hold promise as effective agents for enhancing the growth performance of broiler chickens.

:The aim of this study was to assess the growth performance and profitability of four broiler strains raised in Egypt to identify which strains were most effective and profitable for broiler production in this region. A total of 24000 one-day-old chicks were separately allocated to 4 strain broiler groups: Cobb-500, Avian-48, Ross-308, and Indian River (IR), of the same age and size were used for the study. Each strain group was reared and housed in separate buildings under the same conditions with free access to feed and water. Each strain represented by 6000 birds, divided into five replicates of 1200 broiler chicks per replicate, and was randomly distributed in a completely randomized design into four groups reared to 42 days of age. Live body weight (LBW) and body weight gain (BWG) were recorded weekly. Also, feed consumption (FC), feed conversion ratio (FCR), and livability (%) were determined. The production efficiency factor (PEF), economic indices, and cost-benefit analysis were calculated to assess the profitability of each studied strain group. The results showed that there are significant differences in growth performance and other traits among the four broiler strains. The findings indicated that the Avian-48 and Cobb-500 strains were the most effective and profitable for broiler production under Egyptian conditions. In addition, the IR strain also showed good growth performance and feed efficiency. In conclusion, the study provides valuable insights into the performance and profitability of different broiler strains under Egyptian conditions, which can help inform decision-making in broiler production. By selecting the most effective and profitable broiler strains, producers can optimize their operations and potentially increase their profitability.

: A total number of 350 unsexed 7d old ducks were randomly divided among 7 dietary treatments to investigate using date stone meal (DSM) with or without enzymes (EZ) as an alternative feedstuff in duck’s diet. Dietary treatments were: the 1 st group was used as control and fed control diet contained 0% date stone. Ducks in the 2 nd and 3 rd , 4 th and 5 th and the 6 th and 7 th groups were fed diets contained 10, 15 and 20% DSM either without or with EZ addition, respectively. Results showed that ducks fed basal diet contained DSM at levels of 10%, 15% and 20% and supplemented with EZ had superior (P ≤ 0.05) live body weight, body weight gain, feed intake, economical efficiency, production index and better feed conversion ratio. As well as, increased serum total protein, albumen, dressing % and total edible parts% compared to those fed diets with DSM without EZ. Ducks fed basal diet contained DSM at level 10% and 15% with EZ supplementation recorded higher significantly (P ≤ 0.05) crude protein digestibility and serum HDL. While, there were no significantly differences between groups for digestibility of ether extract and apparent ash retention, serum content of globulin, glucose, T3, T4, total lipids, cholesterol, blood hematological indices and immune organs. In conclusion, DSM could be used in ducks diets up to 20% with enzyme supplementation without adverse effect on growth performance, however, DSM at 10 and 15 % with adding enzyme achieve optimum growth performance and economic efficiency during growing period.

: This study aimed to assess the effect of watery supplementation of probiotic and/or apple vinegar on productive and physiological performances of broiler chickens (Ross 308) reared under high stocking density. Three hundred thirty-six unsexed one-day-old broiler chicks were randomly distributed to eight different treatments (3 replicates each) as follow: T 1 : Negative control (low stocking density (LSD) 12 birds/m 2 ; basal diet with no studied additives in drinking water), T 2 : LSD + probiotic, T 3 : LSD + apple vinegar, T 4 : LSD + probiotics + apple vinegar, T 5 : Positive control (high stocking density (HSD), 16 birds/m 2 ; basal diet with no studied additives in drinking water), T 6 : HSD + Probiotics, T7: HSD + apple vinegar and T 8 : HSD + probiotics+ apple vinegar. Probiotic mixture or/and apple vinegar were provided at a dose of 0.5% in drinking water. The body weight (BW), body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) were measured every growth phase until the end of the study at 35 day of age. Also 6 birds of each treatment were used to evaluate carcass traits. Results revealed that administration of probiotics individually or in combined with apple vinegar significantly increased BW, BWG and FI, with a decreased FCR at grower (21 days of age) phase and market age (35 days of age), while apple vinegar additive groups had the lowest BW, BWG and FI, with increased FCR in both tested stocking density. In addition, enhanced carcass yield, some carcass parts (breast and thigh), blood constituents and beneficial bacteria count in small intestine of broilers provided by additives suggested. In conclusion, this study proves valuable effects of probiotic and apple vinegar on growth performance, carcass traits, and microbiological measurements at grower and finisher phases of broilers raised under high stocking density.

: The current study was conducted to investigate the influence of dietary Arginine levels supplementation on broiler performance, some physiological parameters under summer conditions. One hundred and twenty, one day old unsexed of Arbor Acres broiler chicks, were randomly divided into 4 equal groups in equal 3 replicates of 10 chicks each. The first group was fed control (base diet), the 2 nd ; 3 rd and 4 th groups fed the control diet supplemented with 0.1%, 0.3%, and 0.5% Arginine, respectively. All chicks were maintained under the same management from 1 to 38 days of age. The ambient temperature during this period fluctuated between (30-35 o C). The results were as follows: Compared to chicks given either a control diet or diets supplemented with 0.1 and 0.3% L-Arginine, chicks fed diets containing 0.5% Arginine had significantly the highest final body weight and weight gain values. The two groups received either 0.3 or 0.5 L-Arginine in their diets had recorded the best FCR ratio and the lowest amounts of feed intake at the end of experimental period.
本试验旨在研究夏季条件下饲粮中添加精氨酸水平对肉仔鸡生产性能及部分生理参数的影响。选取1日龄爱拔益加肉仔鸡120只，随机分为4组，每组3个重复，每个重复10只鸡。第一组饲喂对照(基础日粮)，第二组饲喂基础日粮;第3组和第4组分别饲喂在对照饲粮中添加0.1%、0.3%和0.5%精氨酸的试验饲粮。所有雏鸡在相同管理下维持1 ~ 38日龄。试验期间环境温度在(30 ~ 35℃)之间波动。结果表明:与对照组和添加0.1%和0.3% l -精氨酸的饲粮相比，添加0.5% l -精氨酸的饲粮最终体重和增重值显著最高。试验结束时，饲粮中添加0.3和0.5 l精氨酸的两组的饲料效率最高，采食量最低。

: Six blends of medicinal herbs were used in Japanese Quail diet to study their effects on performance, plasma lipids, breast meat compassion, tibia bone characteristics and nutrient digestibly in Japanese Quail. One hundred eighty (180, one-day-old) unsexed quail were divided into six dietary treatments including basal diet with no addition of medicinal herbs (T1), basal diet plus 15 g/kg of herbal blends including; cinnamon and thyme powder (T2), rosemary and anise seed powder (T3), caraway and coriander powder (T4), Fenugreek and cumin seed powder (T5) and parsley and watercress powder (T6). The results showed that chicks were fed T6 mixture of parsley and watercress) achieved high % of crude protein in breast meat of Japanese, while ash% was higher in group fed T4 in which fed mixture diets with fenugreek and cumin. The digestibility of nutrients were significantly (P<0.05) enhanced in T6 except ether extract digestibility and ash retention, which were achieved the highest values in T4 (caraway and coriander) compared with the other groups. Supplementing the diets of Japanese quail with mixture of parsley seeds and watercress at level of 15 g/kg of basal diets resulted significant improvement in the performance, plasma lipid triglycerides, cholesterol, HDL, LDL., breast meat protein, , tibia bone characteristics (tibia weight, length, diameter, ash and robusticty index and nutrient digestibility (protein, calcium, phosphorus and nitrogen). T6 in which chicks were fed basal diet supplemented with 1.5% parsley and watercress powder (50%:50%) achieved the highest net revenue compared with the other supplemented treatments.

: The purpose of this study was to use nonlinear models (NLN)to characterize the growth pattern and estimate the heritability (h 2 ), the genetic (r g ), and phenotypic(r p ) correlation of the body weight (BW) in two distinct genotypes of chicken raising under Egyptian conditions. A data set of 500 chickens with pedigree information was gathered for this study. For this purpose, the BW was measured at hatching (BW0),4 weeks (BW4), 8 weeks (BW8), and 12 weeks (BW 12) of age. Three NLN models (Logistic, Gompertz, and Von Bertalanffy) were used. Using Wombat software, a multi-trait animal model with a restricted maximum likelihood procedure was used to estimate h 2 , r g, and r p for BW.The results showed that Golden Sabahi (GS) had a significantly higher weight than White Leghorn (WL). The growth curve parameters A (mature body weight), B (biological constant), and K (growth rate) were 3989.9, 0.7853, and 0.0624 for WL and 4332.6,0.7897, and 0.0642 for GS in the von Bertalanffy model, 2152.8, 3.8096, and 0.1322 for WL chickens and 2368, 3.8594, and 0.1350 for GS chickens in the Gompertz model, 1304.5, 19.0421, and 0.3382 for WL chickens and 1455.6, 19.6116, and 0.3411 for GS chickens in the logistic model. Three models represented the growth of the two breeds using goodness-of-fit metrics (R2, MSE, and AIC). Heritability estimates of BW at 0, 4, and 8 were higher in GS than WL, while the estimate of BW at 12 weeks of age was almost similar in the both strains GS and WL (0.1). Between BW0 and BW12, there were strong positive genetic and phenotypic correlations compared by the rest of growth traits . Based on the findings of this investigation, we recommend that the two strains can be utilized for selective breeding between the ages of 4 and 8 weeks to increase the overall genetic improvement of growth traits.
