GROWTH PERFORMANCE AND BLOOD CONSTITUENTS OF BROWN AND WHITE JAPANESE QUAIL REARED UNDER HEAT STRESS CONDITIONS
The present study aimed at the evaluation of growth performance, carcass characteristics and related physiological aspects of two different quail genotypes reared under different environmental conditions. A total of 180 quail birds, 8 days of age, of brown and white genotypes were used in this study and divided into two equal groups. Each genotype group was further divided into two subgroups; one subgroup of each genotype was subjected to cyclic heat stress (34˚C/8h, then 24˚C/16h), and the other subgroup was reared under control environment condition (24±1˚C) and served as the control. Feed intake, body weight gain and feed conversion ratio were determined and carcass characteristics were obtained. Blood samples were collected to measure total protein, albumin, cholesterol, triglycerides, AST, ALT, calcium, phosphorus, H/L ratio and total white blood cells. Also, tibia ash, calcium and phosphorus contents were determined. Rectal temperature was recorded. The effect of genotypic variation was noticed in all growth traits and carcass characteristics, revealing that white quail was higher in meat production. The results showed that heated stressed white quail had higher (P>0.01) initial and final body weight than brown quail. The effect of heat stress conditions on blood constituents was prominent. The effect of genotype on blood constituents was not observed, except for the total protein, calcium, AST and ALT. It can be concluded that the white quail genotype has the potential to deposit more meat, especially under high environmental temperature.

PRODUCTIVE AND REPRODUCTIVE RESPONSES OF BREEDER JAPANESE QUAILS TO DIFFERENT DIETARY CRUDE PROTEIN AND L-VALINE LEVELS
The outcomes of dietary crude protein levels (CP; 18 and 20%) and L-valine (Val.; 0, 0.1 and 0.2%) supplementation on the productive/reproductive performance, egg quality and some blood parameters of breeder Japanese quails were evaluated from 14 to 28 weeks of age. One hundred forty-four birds were individually weighed and randomly distributed into six treatment groups with eight replicates each of two females and one male. Body weight, egg weight and percentages of fertility, hatchability and total embryonic mortality were not influenced by treatments. However, significant interactions due to CP and Val. levels on egg production percentage, egg mass, chick weight and egg quality traits were obtained. Quails fed 18% CP + 0.2% Val. diets had better feed and valine intake, FCR, shell thickness and yolk index. Sexual libido, foam production, sperm concentration and motility percentage and methylene blue reaction time (MBRT) did not differ due to treatments while cloacal gland area and semen ejaculate volume of male quail were significantly improved by 18% CP level. No differences between treatments were observed for blood urea and albumin concentrations of male and female. In contrast, total protein and Superoxide dismutase (SOD) concentrations increased significantly in response to Val. levels and were also enhanced differently in the blood of male and female. Superoxide dismutase concentration in the plasma of male was not influenced by treatments while plasma female's SOD was significantly elevated due to 18 % CP + 0.2 % Val. diet. The results indicated that dietary 18% CP with 0.2% L-valine was suitable for breeder quails at 14-28 weeks of age.

EFFECT OF USING DIFFERENT GUAR MEAL LEVELS AND β– MANNANASE SUPPLEMENTATION ON PRODUCTIVE PERFORMANCE OF GOLDEN MONTAZAH LAYING HENS
This experiment was carried out to evaluate the effect of dietary guar meal levels with or without β-mannanase on layer performance. One hundred and sixty eight 22-week-old Golden Montazah pullets divided randomly into seven treatment groups each group had 24 pullets divided into three replicates with 8 pullets per each. The 1st group fed on corn - soybean meal diet and served as control group. The 2nd, 4th and 6th groups fed on diets contain 5%, 10% and 15% guar meal respectively without β-mannanase. The 3rd, 5th and 7th groups fed on diets contain 5%, 10% and 15% guar meal with 250 mg/kg β-mannanase respectively. The experiment was extended for three months to estimate production performance. At the end of the experiment egg quality was assayed and slaughter assay was conducted. The following results were obtained:-Adding 10% guar meal had no harmful effects on egg production performance, however increasing guar meal up to 15% retarded clearly egg production performance compared with control. Remarkable improvements in production performance were observed when β-mannanase supplemented to guar diets.Significant improvement in shell weight percent and shell thickness were observed by increasing guar level up to 15% with or without β-mannanase compared with control treatment, in contrast significant decrease was observed in albumen weight. Neither guar meal levels nor β-mannanase supplementation influenced liver, gizzard, heart and spleen weight percent. All guar meal treatments with or without β-mannanase recorded significantly (P≤ 0.05) lower abdominal fat percent than control treatment. Increasing guar meal than 5% increased significantly (P≤ 0.05) thymus weight percent but supplemented β-mannanase decreased significantly (P≤ 0.05) thymus weight percent.The best relative economic efficiency value recorded for diet that contains 5% guar meal with β-mannanase.

PRODUCTIVE PERFORMANCE, PHYSIOLOGICAL AND IMMUNOLOGICAL RESPONSE OF BROILER CHICKS AS AFFECTED BY DIETARY AROMATIC PLANTS AND THEIR ESSENTIAL OILS
A total number of 378 unsexed 7 d old cobb boiler chicks were randomly divided among nine dietary treatments, with six replicates per treatment, seven birds each, to investigate the effect of sweet basil (Ocimiumbasilicum L.), thyme (Thymus vulgaris L.) and their oils as natural fee7723*23d additives on broiler performance, blood parameters, immune response, and total bacterial count. Experimental chicks were fed the same basal diet and submitted to the following dietary treatments: the first group fed a commercial broiler basal diet without supplementation (control), while the 2nd and 3rd groups fed basal diet supplemented with 10 and 20 g/kg of sweet basil powder, the 4th and 5th groups fed basal diet supplemented with 0.5 and 1g/kg of sweet basil oil, the 6th and 7th groups fed basal diet supplemented with 5 and 10 g/kg of thyme powder and the 8th and 9th groups fed basal diet supplemented with 0.5 and 1g/kg of thyme oil. Growth performance, production index and economical efficiency were calculated. At the end of the experiment (39 d old), some carcass characteristics, blood constituents and bacterial count of the digestive system were measured. Results showed that broiler fed basal diet supplemented with sweet basil, thyme and their oils had significantly greater BW, BWG, economical efficiency, production index compared to control. All supplementations decreased serum AST, ALT, total lipids, triglycerides, cholesterol, LDL and increased T3, TAC, GSH, GPX, SOD, glucose, total protein, γ-globulin, globulin, IgM, IgG, LA, BA, LTT, phagocytic activity, phagocytic index, RBCS and Hb compared to control. All supplementations increased percentage of dressing and total edible parts compared with control. However, all supplementations decreased total bacterial count, Salmonella and E.Coli compared to control.In conclusion, either sweet basil or thyme and their oils could be used safely as a natural growth promoters to improve growth and immune response of broiler chick.

EVALUATION OF USING PROPIONIC ACID AND LIVE YEAST IN DIETS LOW IN PROTEIN AND ENERGY ON BROILER PERFORMANCE
The aim of the present study was to determine the effect of dietary supplementation of either propionic acid (PA), live yeast (Saccharomyces cerevisae) (Sc) or their combination on the performance, carcass characteristics, some blood traits and economical efficiency (EEf) of broiler chicks. Two hundred and fourty unsexed day-old Cobb commercial broiler chicks were distributed randomly into eight treatments, each having three replicates of 10 chicks each. Eight dietary treatments were conducted including, (T1) control group which were fed the basal diet, (T2) control +0.2% (PA), (T3) control + 0.2% (Sc), (T4) control + (0.2% PA + 0.2% Sc), (T5) Control – low by 1.5% protein and 200 Kcal ME /Kg (LPLE), (T6) LPLE + 0.2% (PA), (T7) LPLE + 0.2% (Sc) and (T8) LPLE + (0.2% PA + 0.2% Sc). Results showed that birds fed diets with all additions achieved higher body weight gain BWG compared to control or LPLE. Results of feed intake (FI) showed significantly (P≤0.01) higher values in group T4 compared to all treatments. While, the lowest feed intake (P≤0.01) values were in groups T5, T6 and T7 compared to control. Feed conversion ratio (FCR) improved in all supplemented diets compared to those without supplementation. No significant effect was observed in the average values of giblets (liver, heart, gizzard), and abdominal fat, while all additions significantly (P≤0.01) increased the dressing percentage and total edible parts compared to control or LPLE. Dietary supplements of either PA, Sc or (PA + Sc) increased RBCs, Hb, PCV, WBCs, as compared to control group, but LPLE with different supplements insignificantly affect all hematological parameters as compared to LPLE. Total protein and globulin were significantly (P≤0.01) increased by using all supplements compared to control or LPLE. Total cholesterol and total lipids significantly (P≤0.01) reduced of the chicks fed supplements compared to control or LPLE. Addition of PA, SC and combination of them had significantly (P≤0.01) higher ND titers than control or LPLE. Addition PA, Sc and combination of them to LPLE recorded the best values of (EEf) and (REEf) compared to the other groups. In conclusion, the addition of PA or Sc either alone or in combination to LPLE broiler diet, could improve the performance, carcass characteristics and some blood traits and enhanced the immunity and proved to be a good substitute to antibiotic growth promoters in improving the performance of broiler chicken.

EFFECT OF SPEARMINT (MENTHA SPICATA ) ON PRODUCTIVE AND PHYSIOLOGICAL PARAMETERS OF BROILER CHICKS
This study was conducted to determine the effect of spearmint (Mentha spicata) on productive and physiological performance of broiler chicks. One hundred and eighty day old unsexed (Arbor Acres) broiler chicks were used in this experiment. Birds were distributed randomly into four equal treatment groups, in three replication, 15 chicks each. The dietary treatments including T1(control diet), T2 with addition 0.5% spearmint, T3 with addition 1% spearmint and T4 with addition 2% spearmint. Feed and water were provided ad-libitum. Body weight, body weight gain, feed consumption and feed conversion ratio were weekly recorded. At the end of the experimental period (42 days of age), three birds were randomly chosen to determine both hematological and blood biochemical parameters and carcass traits. The results indicated that the addition of 0.5 and 1% spearmint did not significantly (P>0.05) affect final body weight, total gain compared with the control group, while the supplementation of different levels of spearmint to the diets of broiler chicks improved feed conversion ratio, also there was significant differences between the control group and the groups treated with different spearmint levels on feed consumption. The chickens fed diet supplemented with 2% spearmint had significantly lower body weight, total gain and feed consumption compared to the control group and the other treatments. There were an increase numerically in Hb concentration and red blood cell count in chickens fed diet supplemented with 2% Spearmint compared to the control group and the same group had lower significantly in the total cholesterol compared with the control group and the other groups. Chickens fed diet supplemented with 1% Spearmint had significantly higher concentration of total plasma lipid. There were no significant differences in carcass traits between the control group and the groups supplemented with 0.25, 0.5, and 1% spearmint in chicken diet. There was a significantly higher superoxide dismutase (SOD) activity in group treated with 2% Spearmint. Meanwhile, the chicken supplemented with 1% Spearmint had higher significantly total antioxidant capacity (TAC) compared with the control group and the other treated groups.

RESPONSE OF GROWING RABBITS TO STOKING DENSITY AND DIETARY SUPPLEMENTATION WITH ASCORBIC ACID, AND VITAMIN E UNDER SUMMER CONDITIONS
In factorial arrangement of treatments (2×4), an experiment was conducted to evaluate the effects of stocking density and vitamin C, vitamin E and their combination on growth performance of Californian rabbits during summer season (high ambient temperature of 36.4 ◦C and maximum relative humidity of 97%). Sixty unsexed 7-week-old rabbits were distributed into 8 groups of three replications each. The rabbits were kept in battery cages at two stocking densities; 10 or 15 rabbits/m2 and were fed on four experimental diets; first group was fed the control diet. The other three experimental diets were formulated to contain vitamin C (0.5 g/kg diet), vitamin E (0.25 g/kg diet) or both at the same suggested levels. Growth trial lasted for 7 weeks. The tested criteria included live body weight, live weight gain, feed intake, feed conversion ratio, some blood metabolites and carcass characteristics. Low stocking density increased significantly final live weight, daily weight gain and feed intake. The concurrent administration of vitamin C and vitamin E significantly improved the final body weight, daily gain and feed conversion ratio of rabbits. However, stocking density did not significantly affect feed conversion, carcass traits or plasma blood parameters. The single or combined addition of vitamins C and E significantly increased the percentages of carcass yield and total edible parts. A significant reduction was observed in plasma albumin level due to added dietary vitamin E. The effect of interaction between added dietary vitamins and cage density did not significantly affect most of variables examined in the present study. It can be concluded that stocking density of 10 rabbits/m2 or combined addition of dietary vitamins C (0.5g/kg diet) and E (250 mg/kg diet) may improve rabbit performance during summer season.

PHYSIOLOGICAL AND IMMUNOLOGICAL PERFORMANCE OF DOMYATI DUCKLINGS FED DIFFERENT LEVELS OF COCONUT OIL
This study aimed to determine the effect of dietary supplementation of coconut oil levels on some physiological and immunological responses in ducklings during growing period (28-89 day of age). A total number of 120 Domyati ducklings, 28- day old were used, weighted 530-545 g and divided into four experimental groups, each of three replicates to determine the effects of feeding diets contained different levels of coconut oil (CO) as a medium chain fatty acids (MCFA) source. The experimental groups were arranged as follows: The first as a control group (G1) which received basal diet without any supplementation, while the second, third and fourth groups (G2, G3 and G4) were received diet contained CO by 1.0, 1.5 and 2.0 %, respectively. The results revealed that, percentages of heterophils and lymphocytes were significantly (P≤0.01) lower and higher, respectively, for Domyati ducklings in G4 than those in the control group (G1). Some blood hematological values (Hb and RBCs) did not significantly affected by different CO levels. The ratio of hetrophil to lymphocytes (H/L) was significantly (P≤0.01) lower for Domyati ducklings in G2 and G4 than those in G1. Spleen and thymus indexes were significantly (P≤0.05) increased in treated groups compared to the control one. Moreover, dietary CO levels caused to increase the values of plasma IgG, IgM and IgA concentrations than that of the control group. The different dietary levels of CO significantly influence the lipid peroxidation (LPO) by decreasing MDA values. Conclusively, ducklings fed diet supplemented with 1.5 or 2% CO had heavy immune organs weights, and high plasma levels of immunoglobulins, which collectively suggested as an improvement in the immune response.

THE EFFECT OF ADDITION OF CHAMOMILE FLOWER TO SUDANI DUCKLING DIETS DURING GROWING PERIOD ON GROWTH PERFORMANCE, BLOOD PARAMETERS AND ECONOMIC EFFICIENCY
A total number of 225 Sudani ducklings at one-day-old were used, weighed and divided into three experimental groups (each of three replicates) to investigate the effect of dried chamomile flower (DCF) addition at different levels (0.0, 1.0 and 3.0 g/kg) on growth performance, carcass traits, blood parameters and economic efficiency. The results indicated that dietary DCF with 1.0 g/kg resulted in a significant (P≤0.01) increased in live body weight at 16 weeks of age, while body weight gain, and performance index were significantly (P≤0.05) improved as compared to the control group during the overall experimental period (0 -16 weeks of age). In spite of, eviscerated carcass and total edible parts (%) were not significantly affected by different levels of dietary DCF addition, but abdominal fat (mg/100 g LBW) was high significantly (P≤0.01) decreased. Relative weights of gizzard and total giblets were significantly (P≤0.05) higher in ducklings fed diet supplemented with 1.0 g DCF. Plasma total lipids, cholesterol, triglycerides and low-density lipoproteins (LDL) cholesterol were significantly decreased by supplementing DCF with 1.0 and 3.0 g/ kg diet. Plasma liver function parameters were significantly increased as a result of diet addition with DCF except globulin which was significantly decreased. Hemoglobin (Hb) and red blood cells (RBCs) were insignificantly affected by DCF treatments, however, treatments caused significantly increased in white blood cells (WBCs). Economic efficiency was improved for ducklings fed diets supplemented DCF with 1.0 g /kg diet. The obtained data suggest that dietary DCF 1.0 g/kg for Sudani ducklings during growing period may be could improve growth performance and economic efficiency besides, reduce abdominal fat, total lipids, cholesterol, triglycerides and LDL cholesterol.

INFLUENCE OF SPRAYING GARLIC OIL ON EMBRYONIC DEVELOPMENT, HATCHABILITY, PHYSIOLOGICAL PARAMETERS, POST-HATCH CHICK GROWTH AND BACTERIAL CONTAMINATION OF FERTILE QUAIL EGGS
Garlic oil has a strong antibacterial activity against a wide range of gram-negative and gram-positive bacteria as well as, antifungal properties. This study aimed to assess the effects of spraying fertile hatching eggs of Japanese quail with garlic oil solution on embryonic development, hatchability, physiological parameters, post-hatch chick growth and bacterial load on eggshell surface. Four hundred hatching eggs of Japanese quails were equally divided into four treatment groups. Eggs of the first group served as a control group without any treatment. Also, eggs of the second group served as a control but sprayed only with distilled water. Eggs of the third and fourth groups were sprayed by 1ml/liter and 2ml/liter garlic oil solution, respectively. Embryo weight, shank length, body length as well as, chick weight, chick shank length, chick body length and hatchability tended to be higher significantly (P<0.05) in eggs treated with garlic oil solutions when compared with control eggs. While hatch time, embryonic mortality, egg albumen weight ratio, egg shell thickness and egg weight loss ratio at 14 days of incubation were significantly (P<0.05) decreased in eggs sprayed with garlic oil solutions when compared with control eggs. Blood hematological parameters (RBCs, Hb and PCV), plasma total protein, albumin, total lipids, hormones, immunoglobulin G (IgG) were significantly increased (p<0.05), while plasma glucose was decreased. There was no effects on plasma cholesterol compared to control. WBCs count was slightly increased in number in response to spraying with garlic oil solution. Carcass constituents of chicks at hatch and growth performance (body weight, feed intake and body weight gain) of chicks at 14 days of age recorded significant higher values and improved feed conversion in response to spraying with garlic oil solutions. In contrast, yolk residual of chicks at hatch was lower than control group. Application of garlic oil had significant influence on TBC on the surface of egg shell either at one week or after two weeks of incubation compared to control groups. Intestinal total aerobic, anaerobic micro-flora counts and the count of total coliform of chicks were decreased.In conclusion, Spraying Japanese quail eggs with garlic oil solution as natural disinfectants (pre-incubation) is a good way to improve embryonic development, hatchability, blood constituents, hormones and immunity of hatching chicks and lowering the bacterial contamination of eggshell surface of quail eggs.

A NUTRITIONAL EVALUATION OF SUGAR BEET PULP AS UNTRADITIONAL FEEDSTUFFS IN GIMMIZAH CHICKEN DIETS DURING THE PERIOD FROM THREE UP TO EIGHT WEEKS OF AGE
This research was conducted to study the effect of using sugar beet pulp (SBP) in the diets of Gimmizah chicks and its effect on the chicks performance of during the period from three to eight weeks of age. A total numbers of 400 one-day old unsexed Gimmizah chickens were firstly fed a control diet for two weeks. At same age, birds were equally divided into five treatments (80 birds each), each treatment were subdivided into four replicates (20 birds each). The treatments consisted of five levels of SBP (0, 5, 10, 15 and 20% of the diet), chicks were fed starter diets from the beginning of the third (3rd) week up to 8 weeks.Chicks fed diet containing 0% SBP had higher (P0.001) live body weight (LBW), body weight gain (BWG), feed intake (FI), growth rate (GR) and performance index (PI) during the period from 3-8 weeks. Inclusion of 5% SBP in the Gimmizah diets recorded better values (P0.001) of feed conversion ratio (FC), crude protein conversion (CPC) and caloric conversion ratio (CCR) during the period from 3 to 8 weeks (differences between 0, 5, 10 and 15% SBP were not significant). While, those fed 20% SBP in the diet had the lower values of LBW, BWG, FI, GR, PI and the worst values of FC, CPC and CCR during the same period. Chicks fed diet containing 5% SBP had the best values of economical and relative efficiency, while, those fed 20% SBP had the lowest values.The obtained results show that the SBP could be used at a rate of 5% in the starter (from 3 to 8 weeks) diets of Gimmizah without any adverse effects on the chicks performance. But, the inclusion of SBP at 20% in the diet resulted in poor performance.
