Two hundreds females and 80 males of Japanese quails were selected and distributed randomly into 10 experimental treatments with 4 replicates per each. Each replicate hold 5 female and 2 male. Ten experimental supplementations were added to basal diet (control treatment) to compose 10 experimental treatments. The other 9 treatments were formed by adding 0.5gm oxytetracycline (20%) /kg diet, 200mg vitamin C/kg diet, 20mg vitamin E/kg diet, 1gm pectin/kg diet, 20gm entire fresh lemon (fully grinded) /kg diet, 250 mg silymarin (Si) /kg, 250 mg curcumin (CR) /kg, 500 mg SI /kg and 500 mg CR /kg respectively. The experiment extended from 8 weeks of age up to 2 months of egg production. The results showed that: Egg production performance of quail fed diet supplemented with fresh lemon equalized with vitamin E and recorded (p ≤ 0.05) significantly higher egg production performance than vitamin C, pectin, antibiotics and other plant feed additives. On contrast laying quail fed diet supplemented with 500 SI mg CR/kg recorded numerically the highest fertility and hatchability percent. Similarly egg quality improved numerically with silymarin supplementation. The results of this experiment recommend that some plant feed additives that are available with low cost may be able to substitute antibiotics, synthetic vitamins and prebiotics in diets to improve performance of laying quail reared under chronic heat stress.","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":"76107977","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 500 eggs from Arbor Acres breeder hens were weighed and distributed into five treatments with four replicates for each. At day 18 of incubation, eggs of the first group were non-injected and served as control, while the 2 nd group was injected with normal saline at 0.9 % (saline group). But, the 3 rd group was injected with selenium nanoparticles (SeNPs) (20 μg SeNPs/ egg) the 4 th group was injected with nicotinamide (NAM) (300 mM NAM/ egg) and the 5 th group was injected with their mixture (20 μg SeNPs plus 300 mM NAM/ egg). The results showed that chicks of saline and mixture in-ovo injection groups had higher significant weights at hatch compared to all other studied groups. In contrast, eggs of the in-ovo NAM injected group had higher hatch of fertile egg percentage values with insignificant differences with both control and mixture injected groups. The chicks of NAM and mixture in-ovo injected groups had significantly highest WBC values compared to all other studied treatments. The chicks of SeNPs, NAM, and mixture in-ovo injected groups have significantly higher low-density lipoprotein compared to control and saline groups. This suggested that the in-ovo injection with NAM and the mixture groups used in the present study had a considerably positive effect on hatchability percentage, chick weight, relative chick weight, white blood cell count, and blood glucose level and the activity of total antioxidant capacity (TAC). In conclusion, injection of eggs in-ovo of broiler chicks with 300 mM nicotinamide/ egg and mixture between 20 μg SeNPs plus 300 mM NAM/ egg enhanced hatchability and some physiological traits for chicks.","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":"84595022","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 factorial completely randomized design (3×3), three dietary protein levels (24, 21.6 and 19.2%) without or with two feed additives was used. Five hundred and forty quails were randomly divided into nine groups, kept in cages, fed their respective experimental diets and managed similarly from 2 to 6 weeks of age. The obtained results illustrated that growth performance of quails did not affected by dietary protein level. Quails fed enzyme-enriched diets achieved better feed conversion than the control birds. Feeding yeast-supplemented diets improved the final body weight and weight gain of quails compared with the control birds. Economic efficiency of feeding (EEF) and carcass characteristics were not influenced by dietary protein level, feed additives and their interaction. In conclusion, decreasing dietary CP level from 24 to 19.2% does not compromise the growth performance, economic efficiency or carcass traits of quails. Dietary yeast supplementation has a beneficial effect on growth performance of quails, regardless of dietary CP level.","PeriodicalId":11662,"journal":{"name":"Egyptian Poultry Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81069288","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}
