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.","PeriodicalId":11662,"journal":{"name":"Egyptian Poultry Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":11662,"journal":{"name":"Egyptian Poultry Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135691009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":11662,"journal":{"name":"Egyptian Poultry Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80181724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":11662,"journal":{"name":"Egyptian Poultry Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91286741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
