Sixty growing New Zealand White (NZW) rabbits aged 8 weeks were divided randomly into four equal groups with three replicate (5 rabbit in each). Rabbits were distributed into four dietary treatments included a control diet without any feed additive, a diet containing 150mg Vit E /kg diet, Vit E, a diet containing 100 mg LGO /kg diet anda diet containing 150 mg LGO /kg diet during the growth period. Rabbits were fed to allow ad-libitum in feeding trial lasted 56 days. \u0000The results showed that rabbits fed diet contain 150 mg Vit E /kg diet and 150 mg LGO /kg diet recorded significantly higher final live weight and total weight gain as compared to the control and group fed diet contained 100 mg LGO /kg diet. Rabbits fed dietary 150 mg LGO recorded the best feed conversion ratio. The digestibility coefficients for CP and nutritive values in terms DCP and TDN of were significantly higher with Vit E and LGO supplementation. Supplementing 150 mg/kg diet Vit E increased significantly (P<0.05) OM digestibility coefficient. Adding LGO supplementation to rabbit diets significantly (P<0.01) increased carcass, dressing and total edible parts percentages. However, there were no significant differences between groups for heart, kidney, liver and giblets percentages. Total cholesterol content in meat decreased significantly (P<0.05) decreased in group fed 150 mg LGO as compared to the control group. Triglycerides and MDA concentrations were significantly lower in treatments group when compared with the control. There were no significant between experimental diets in pHu of meat, while drip loss % were significantly (P<0.05) decreased compared to those of the control. \u0000Conclusively, it could be concluded that adding lemongrass oil or vitamin E as feed supplementation in growing rabbit's diet improved growth performance, digestion coefficients dressing percentages and meat quality. Also, supplemented rabbits diet 150 mg LGO/kg diet led to improvement economic efficiency than that of 150 mg Vit E/ kgdiet and free from additives. \u0000Keywords: Lemongrass oil, Vitamin E, Growth performance, Nutrients digestibility, Carcass characteristics, \u0000 Meat quality.","PeriodicalId":11684,"journal":{"name":"Egyptian Journal of Rabbit Science","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89900735","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}

The animals were randomly allotted into three experimental groups (30 each). The first group (A) was fed the basal diet as control, while the second (B) and third groups (C) were fed diets containing Moringa oleifera hay as a replacement of 50% and 75% of alfalfa hay in the basal diet, respectively throughout the growing period (5-13 week of age). \u0000The obtained results  showed that rabbits fed Diet C increased significantly (P<0.01) haemoglobin (Hb) and hematocrit (Hct) as compared with those fed Diet B and Diet A (control group). However, the differences in red blood cell (RBCs), white blood cell (WBCs), platelet (Plt), neutrophils, lymphocytes, mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) were not significant. Moreover, all values of blood haematological parameters are within the normal range for healthy rabbits. The differences in total protein, albumin, globulin, A/G ratio, aspartate amino transferase (AST), alanine amino transferase (ALT), bilirubin, urea-N and creatinine among the experimental groups of growing NZW rabbits fed different level of Moringa oleifera hay and control group were not significant. Sections from spleen, liver and kidneys of rabbits fed different level of Moringa oleifera hay (leaves +twigs) as a substitute for alfalfa hay in the diet showed normal hiso-morphological structures as control. Testis of male rabbits fed Diet A (control), Diet B and Diet C showed normal spermatogonia, spermatocytes and spermato cytogenesis processes.

Four genetic groups of APRI (A-line), Moshtohor (M-line) and their simple F1 cross (½A½M) in addition to V-line rabbits (as a reference population) were used in this study.PCR-RFLP technique was applied using BstUI restriction enzyme SNP for genotyping the growth hormone gene (GH) (TT, TC and CC) genotypes. Heritabilities estimated by VCE program for body weights and daily weight gains were mostly low or moderate and ranging from 0.05 to 0.18. The percentages of direct additive effects on body weights were significantly (P<0.01) in favour of Moshtohor line by 2.7, 4.3, 1.4, 2.6 and 2.9 % at 4, 6, 8, 10 and 12 weeks and by 8.7, 15.9 and 18.6 % in daily weight gains at DG4-6, DG6-8 and DG8-10, respectively. The percentages of maternal effects on body weights at 4, 6, 8, 10 and 12 weeks were also significantly in favour of Moshtohor line by 2.8, 5.4, 3.5, 3.5 and 3.1%, respectively and ranged from 1.8 to 15% for daily weight gains in weight. The percentages of direct heterosis were significantly positive by 3.1, 8.1, 8.2, 5.2 and 3.8 % for body weights at 4, 6, 8, 10 and 12 weeks and by 13.0, 7.8 and 9.6% for daily weight gains at DG6-8, DG8-10 and DG10-12, respectively. The associations of the genotypes of GH gene were polymorphic and had significant effects on most growth traits (P<0.05). There were significant differences (P<0.05) between the generalized least square means of the different genotypes (TT, CC and TC) of GH gene for body weights at 4, 6, 8, 10 and 12 weeks of age in V-line, M-line, A-line and ½A½M cross rabbits. The TC genotype was positively associated with an increase in body weights of V-line, M-line and A-line rabbits, while the TT genotype indicated an increase in body weights of ½A½M rabbits. The significant associations between GH gene and growth traits confirmed that this gene could be a candidate gene and may be used in Marker-assisted selection (MAS) to improve growth performance in rabbits.Conclusively, GH gene could be used as a candidate gene in genetic improvement programs to improve growth performance in rabbits.","PeriodicalId":11684,"journal":{"name":"Egyptian Journal of Rabbit Science","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73798212","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}
