This study was conducted to evaluate the effect of different levels of Ginger (Zingiber officinale) on growth performance, immunity response, some blood biochemical and hematological parameters of quail birds. 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, highdensity 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, immuneresponsiveness and it could be considered as a growth promoter agent for quail birds.

The present work was designed to study the effect of using some untraditional energy sources produced in north Sinai on the performance and physiological characteristics of broiler chicks under north Sinai environmental condition. In this respect, yellow corn, as the main source of energy, was substituted by olive pomace meal and orange west meal at rate 3, 6 and 9%, each alone in different diet formulated on the basis of economic efficiency and isonutritive value. A total number of 400 one day old Hubbard broiler chickens were brooded up to 45 day of age. Chicks were given iso-nitrogenous and iso-caloric diets and assigned in two stages of growth. The started from 7 to 28 day old, while the second was durated from 28 until 45 day of age. The results indicated that the waste product from the manufacture of orange west meal at rates of 9% and 6% and olive pomace meal 6% without the occurrence of any side effects either on production performance or physiological characteristics of the bird as those ratios achieved the best results in terms of production and economic efficiency, the proportions of the rate, respectively.

This study was carried out to evaluate the effect of using ginger (Zingiber officinale) in laying quail diets on egg production, egg quality and blood parameters. A total of 120 female quails at 10-weeks old were used with four treatment groups, in three replicates for each treatment, and 10 birds per replicate. The first group (control) was fed a basal diet. Second, third, and fourth treatments were fed on diets containing ginger roots powder at levels of 0.25, 0.5, and 0.75% of the diet. Egg production and exterior and interior quality of eggs were measured over eight-week period. At the end of the experiment period three birds were taken randomly from each treatment and slaughtered to evaluate blood parameters. The results showed that the groups fed diets containing ginger recorded a highly significant difference in egg production, egg number, egg mass, and average egg weight compared to the control group. On contrary, egg quality did not show any statistically significant differences except eggshell percentage, egg shape index, the weight of albumin, and yolk which was for the benefit of the groups fed diets that contain ginger. In addition, using ginger in quail diets decreased total cholesterol, LDL-cholesterol, glucose, ALT and AST and increase total protein, globulin, albumin and HDL-cholesterol. Also, results showed a highly significant difference in LH, FSH, and Estradiol hormones in groups fed diets containing ginger compared to the control group. In conclusion, the results of this study showed that the using ginger up to 0.75% seems to have a positive influence on egg production, egg quality and blood biochemical parameters in laying quail birds.

This experiment was conducted to evaluate the effect of different levels of Nigella sativa meal (NSM) on performance, immunity and some blood biochemical and hematological parameters of broiler chicks. A total of 120, one day-old broiler chicks (Hubbard) were divided into four treatment groups, with three replicates per treatment and 10 chicks per replicate. Chicks in control group were fed basal diet. Birds in treatment groups were fed on diets supplemented with 3, 6 and 9% NSM. Body weights of broilers were measured at one, 21 and 42 days, feed intake was measured at the same periods and feed conversion was calculated, accordingly. Blood samples of three birds per replicate were collected at 30 and 42 days of age from wing vein were taken for biochemical and hematological analysis. At ages 30 and 42 days, two chicks (one male and one female) 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 3 and 6% of NSM improved body weight gain (BWG) and feed conversion ratio (FCR) of broilers at starter and grower periods (P<0.05), and also increased serum albumin levels (P ≤ 0.05). Total protein and glucose levels were not statistically (P ≥ 0.05) influenced. Supplementing 3 and 6% N. sativa meal decreased serum triglyceride and plasma cholesterol had lower level in all treatments compared with control. In addition, HDL fraction was increased and LDL fraction was decreased in all treatments compared to control group. Birds fed NSM except 9% insignificantly improved spleen percentage and improved significantly bursa and thymus percentages compared with control group. Plasma AST and ALT decreased with all levels of NSM and could suggest that has properties to enhance liver health. In conclusion, results of this study showed that addition of 3 and 6% of NSM seem to have a positive influence on growth performance, blood biochemical, immune-responsiveness and economic efficiency and it could be considered growth promoter for broiler chicks.

The present study was carried out in the farm of the Department of Animal and Poultry Production, Faculty of Environmental Agricultural Sciences, Arish University. This study was carried out to investigate the effect of supplementing Moringa oleifera leaf meal (MOLM) on the growth performance and blood biochemical parameters of growing quails. A total of 180 seven days, unsexed quail chicks were randomly divided into four experimental groups. Each group was further subdivided into 3 replicates, 15 chicks per each. Four levels of MOLM (0.0, 0.2, 0.4 and 0.6%) were used during the experimental period from 7 to 42 day of age. The results showed that final body weight and body weight gain were increased significantly (P<0.05) at the 0.2% level of MOLM; also, feed intake had the same trend, however, there is no significant effect on feed conversion values among treatments. The levels of MOLM significantly increased dressing percentage, head, liver, heart, gizzard and total edible parts weight except 0.6% level of MOLM. Blood globulin and albumin increased significantly (P<0.05) with increasing the level of MOLM. Total protein was not affected by inclusion of MOLM in quail diets. Plasma cholesterol had lower level in all treatments compared to control. In addition, HDL fraction was increased, while LDL decreased significantly in all treatments compared to control group. However, Plasma AST and ALT decreased at all levels of MOLM compared to control group.It could be concluded that addition of Moringaoleifera meal leaves up to 0.2% improved growth performance, carcass characteristics and blood parameters of the quail chicks.
