A total of 40 New Zealand White (NZW) rabbits does 6-month of age, with an average body weight (2500±100 g), were randomly divided into four equal treatment groups. 1 st group (control) was fed a basal diet. The 2 nd , 3 rd and 4 th treatments were fed on basal diet supplemented with 2.5, 5 and 7.5% of MOLM, respectively. Diets were provided to does throughout the experiment. Blood samples were collected at the end of the experimental period at 9 months of age from the marginal ear vein from each female rabbit for biochemical, hematological analysis and hormonal assay using standard procedures. In addition, conception rate (CR), litter weight (LW), litter size (LS), gestation length (GL) and milk yield (MY) were determined. Results showed that, using moringa in the diets of female rabbits caused significant improvement in their reproductive performance parameters and achieved the highest rates in CR, LS, LW and MY compared with control group. In addition to higher rate of reproductive hormones such as FSH, LH, estrogen and progesterone and a decrease in LDL-cholesterol and total cholesterol in rabbits fed on moringa compared to control. It was also noted that there was an increase in the levels of serum total protein and HDL-cholesterol in the same groups compared with control group. Whereas plasma ALT and AST decreased with all treatments of MOLM and this indicated that moringa has a role to improve liver health. It was also noted that there were significant differences between all treatments with regard to hemoglobin (Hb), white blood cell (WBC) and lymphocytes. In conclusion, supplementing rabbit diets with 2.5, 5 or 7.5% of MOLM showed positive effects on hematological and biochemical blood parameters, physiological response, hormonal changes and reproductive activity of female rabbits, and it could be used as a sexual promoter for female rabbits.","PeriodicalId":11662,"journal":{"name":"Egyptian Poultry Science Journal","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76120272","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 number of 132 Mamoura laying hens (120 hens + 12 cocks), 36 weeks (wk.)-old, was used in a completely randomized design and randomly assigned into four dietary treatments as follow: L-carnitine at 0, 150, 300 and 450 mg/kg, each group was included on three replications (10 hens +1 cock in each replicate) and was kept until 48 weeks of age. Results revealed that supplementing different levels of L-carnitine resulted insignificant improvement in feed intake, laying %, fertility, hatchability % of fertile egg and hatchability % of setting egg. Also, the results showed that egg weight, egg mass, Chick weight at hatch liver weight % and heart weight % were significantly increased by feeding diets supplemented with L-carnitine. In hens fed diets supplemented with L-carnitine, feed conversion, mortality percent, serum albumin, cholesterol, serum triglycerides, low density lipoprotein, and aspartate transaminase enzyme levels were all significantly lower.

A total of 180, one day-old quail birds were divided into four treatment groups, with three replicates per treatment and 15 birds per replicate. Birds in control group were fed basal diet. Birds in treatment groups were fed on diets supplemented with 0.25, 0.50 and 0.75% Ginger. Body weights and feed intake of birds were measured weekly. Feed conversion was calculated, accordingly. Blood samples of three birds per replicate were collected at 42 days of age for biochemical and hematological analysis. At the end of experiment, three birds were taken randomly from each replicate and slaughtered, and the spleen, thymus and bursa were separated and weighted. Results of this experiment showed that, supplementing of Ginger to quail diets improved body weight gain and feed conversion ratio of quail birds (P<0.05), and also increased total protein and albumin levels (P ≤ 0.05). On the other hand, supplementing Ginger decreased serum triglyceride and plasma cholesterol levels in all treatments compared with control. In addition, high-density cholesterol fraction increased and low-density cholesterol fraction decreased in all treatments groups compared with control group. Birds fed Ginger significantly improved spleen, thymus and bursa percentage/body weight compared with control group. Plasma ALT and AST decreased in all levels of Ginger and could indicate good liver health. In conclusion, results of this study showed that addition of Ginger showed a positive influence on growth performance, blood biochemical parameters, immune-responsiveness and it could be considered as a growth promoter agent for quail birds.","PeriodicalId":11662,"journal":{"name":"Egyptian Poultry Science Journal","volume":"147 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74536289","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}

Six hundreds of hatching eggs were randomly separated into 4 treatments (each treatment represented with three replicates). The experimental groups were arranged as follows, the 1st group (T1) used as positive control (which eggs were fumigated with formaldehyde, the second group (T2) was sprayed with distilled water as a negative control, third group (T3) was sprayed with garlic oil solution 2ml/litter and the fourth group (T4) sprayed garlic oil solution 3 ml/litter. Results revealed that chick weight, chick shank length, chick body length and hatchability tended to be significantly higher (P<0.05) in eggs treated with garlic oil solutions when compared to control group. Embryonic mortality and egg weight loss ratio during 18 days of incubation were considerably (P0.05) lower in eggs sprayed with garlic oil solutions as compared with control group. Blood haematological parameters (RBCs, Hb, and WBC) were unaffected at hatch and at 28 days, with the exception of a modest rise in WBC count at 28 th day in response to spraying with garlic oil solution. In response to spraying garlic oil solutions, carcass contents of chicks at hatch and growth performance (body weight, feed intake, and body weight gain) of chicks during the experimental period (28 days showed significantly higher values and feed conversion improvement, while the residual yolk of chicks at hatch, , was lower than those in the control group. Comparing to control groups, garlic oil application had a substantial impact on TAOC at hatch and after 4 weeks of age. Cholesterol, triglyceride, plasma total protein, albumin, LDL and HDL were significantly differed (p<0.05). We concluded that pre-incubation spraying of eggs with garlic oil solution as a natural disinfectant is an effective way to improve hatchability, post-hatch chick development, and physiological response of hatched Sinai chicks.","PeriodicalId":11662,"journal":{"name":"Egyptian Poultry Science Journal","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84070900","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 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. 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 st 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.
