BODY COMPOSITION, METABOLIC STATUS, IMMUNE RESPONSE AND INFLAMMATIONS IN RABBITS DURING LACTATION
This experiment was carried out to investigate the influence of lactation on body composition, metabolic status, immune response and inflammation occurrence in V-line doe rabbits. A total number of 30 V-Line primiparous female rabbits were divided into two equal groups; 1st group: females were kept as non-pregnant and non-lactating (NPNL, group) and 2nd group: females were kept as lactating (L, group). Animals were fed ad-libitum a commercial pelleted diet contains 18.5 % crude protein, 14.5 % crude fiber, 2.5 % fat and 2730 kcal/kg digestible energy. The number of suckling kits was adjusted to 8 per litter; the kits were weaned at 30 days. Average feed intake (g) was weekly recorded. Body composition of does was determined by BIA technique using bioelectrical body composition analyzer (Quantum II) apparatus. Blood samples were collected from does through three stages of lactation period; early (within 2-3 d post partum), mid (14 – 15 d of suckling) and late (30 d of suckling). Blood serum was assigned for total protein, albumin, glucose and cholesterol determinations. Globulin and albumin/globulin (A/G) ratio were calculated. Concentration of T3 hormone, Tumor Necrosis Factor – Alfa (TNF-α) and Inerleukin 2 (IL-2) were estimated by using ELISA technique. The results illustrated that feed intake of does significantly increased during lactation period. In L does, body content of humidity, protein and ash were significantly higher; in contrast, fat and energy content were significantly lower. No significant differences were found in cholesterol, glucose, albumin, A/G ratio, T3 and TNF-α through stages of lactation. While, significant differences were obtained in total protein, globulin and IL-2 at mid and late stages compared to early stage of lactation. In conclusion, stressed does, which suckle high number of pups (n ≥ 8) should be kept under especial nutritional care because energy balance is negative during lactation and fat stores are mobilized, especially in primiparous does.

USING THE TECHNIQUE OF BIOELECTRICAL IMPEDANCE ANALYSIS (BIA) TO ESTIMATE BODY COMPOSITION OF RABBITS THROUGH GESTATION AND LACTATION PERIODS
This study was performed to determine in vivo body composition of V-line doe rabbits through gestation and lactation by using Bioelectrical Impedance Analysis (BIA) technique. A total number of 45 V-line primiparous female rabbits aging 6-7 months were divided into three groups; 1st group: females were kept as pregnant (P, group), 2nd group: females were kept as lactating (L, group) and 3rd group: females were kept as lactating and pregnant in the same time (LP, group). Nine bucks (6 - 8 months age) were used for natural mating throughout the present study. The number of suckling kits was adjusted to 8 per doe, the kits were weaned at 30 days in L does group and 28 days in LP does group. Average feed intake (g) was weekly recorded. Body composition of does was determined by BIA technique using bioelectrical body composition analyzer (Quantum II) apparatus. Feed intake of P does group was increased (P

USING EARLY LIVE BODY PERFORMANCE TRAITS OF DUCKS TO PREDICT MARKETING WEIGHT
Data from five hundred and seventy four male ducks of Sudani (SUD, N= 290) and Muscovy (MUS, N= 284) breeds have been used to predict marketing weight (MW) at 12 weeks of age, employing three early live body performance traits (LBPTs) at 2, 4 and 6 weeks of age, viz keel length (KL), breast girth (BG) and body weight (BW). The results indicated that BW, KL and BG increased with advantage of age. The average daily gain of BW was found to be decreased between the two age stages (2-4 and 4-6 wks), while KL and BG increased in both breeds. BW demonstrated the highest coefficient of variation (CV%) among all LBPTs at all growth stages for the two breeds. For 2-week SUD ducklings, MW had a single linear relationship with KL (coefficient of determination, R2, = 61%), BG (R2 = 41%) and BW (R2 = 3%). In SUD breed, R2 showed increases to 74%, 68% and 79% when combining KL with BW at 2 weeks, KL with BG at 4 weeks and BW with BG at 6 weeks. MW of MUS ducklings at 2 weeks, showed to be in a simple linear relationship with KL (R2 = 15%) and BW (R2 = 74%). Increases in R2 to 84%, 86% and 91% were noticed when combining KL with BW at 2, 4 and 6 weeks, respectively. Admittance of a third variable did not increase R2 more than 9% whatever the age group or breed. However, for practical purposes, as early as 2 weeks of age, MW appeared to be predictable from early live body performance traits especially with KL in SUD duckling birds and BW in MUS duckling birds.

EFFECT OF ADDING BEE BREAD AND BEE POLLEN AS ANTIOXIDANTS ON PRODUCTIVE PERFORMANCE AND FUNCYIONAL PROPERTIES OF HY-LINE HENS STRAIN
The objective of this study was to investigate the effect of dietary bee bread (B), bee pollen (P) and their mixtures (BP) as antioxidants on productive performance and functional properties of table eggs in Hy-Line hens strain. A total number of 1000 Hy-line (W36) hens (27-wks-old) were weighed and randomly distributed into ten experimental groups, 100 birds each; five replicates (20 hens). The experimental design consisted of ten experimental groups as follow, the basal diet without B or P, the second diet was contained 0, 0.015 % butylated hydroxytoluene (BHT) (positive control) and other dietary treatments divided into eight groups include graded levels of B (0.1, 0.15, 0.2 %), P (0.1, 0.15, 0.2 %) and combination between B+P (0.05+0.05% and 0.1+0.1%). Results indicated that all the experimental diets produced greater egg number than control diet, but a clear improvement was observed in the hens fed diet contained 2g P/Kg diet followed by the diets supplemented with 0.15% P and 0.1%B+0.1%P. Egg mass/hen was significantly improved by the diet contained 2 g P /kg diet comparing with the control diet. The diets supplemented with 0.2% B, 0.15% P and 0.1% B recorded significantly lower values of triglycerides in fresh eggs yolk than control diet. The total cholesterol in stored yolks ranged from18.02 to 45.99 mg/ dl in the hens fed diets with BHT, 0.2% P, 0.1% B + 0.1% P, 0.15% B, 0.15% P and 0.2% B respectively while it was 63.79 mg/dl in control diet. The digestibility coefficient of ether extracts was significantly improved by the diet with 0.15% B and 0.15% P compared to the control diet. The diet contained 0.05% B+0.5% P, 0.2% B, 0.15% P and 0.2% P resulted in significantly higher serum total antioxidant records than control diet. Indeed. 0.2% B, 0.15% B, 0.1% P and 0.1% B in HY-Line hen's diets can be used as a antioxidant to enhance the production performance and internal egg yolk quality which are essential demand for consumer healthy "organic products".

EFFECT OF SEMI-CLOSED AND CLOSED HOUSING SYSTEMS ON LAYERS PRODUCTION AND ECONOMICAL PERFORMANCE
This study was carried out to investigate two main table-egg production systems, semi-closed and closed and their effect on some productive traits of laying hens in Al-Sharkia governorate. Two commercial table-egg production farms were surveyed, one farm of semi-closed system named Ebrahemia and another farm of closed system was Salhia, both farms have layers flocks from Lohmann brown (L.B) strain. Completed three production cycles data from year 2011-2015 were obtained of each one and compared with others and with their standards. The comparison between Ebrahemia and Salhia farms with Lohmann brown strain under semi- closed and closed systems respectively, at age of 52 wks of production and also at the end of production cycle indicated that hens kept under closed system had significantly the best age (day) at 50% of production, mortality percentage, hen day %, hen housed egg number, while feed conversion (g / Egg) and hen housed percentage were also better under the closed system than the semi closed system but the differences were not statistically significant. In General, production efficiency coefficient value was significantly higher (364.79 and 326.13) for Salhia farm than Ebrahemia farm (286.94 and 274.12) at (52 wks and the end) of production cycle, respectively. Moreover, the economical study showed the significantly superiority of closed system‘s economical efficiency characters than the semi-closed, the efficiency of every spent pound was better in the closed system, while the difference of layer cost was not significant. Finally, results indicated that Lohmann brown layers showed more efficient production performance under closed system than semi- closed system in Al-Sharkia governorate.

: The aim of the study was to investigate the effect of supplemented chicken diets with 2% and 4% arginine (Arg) above NRC (1994) requirements on growth performance, immune response and gene expression of gene (y + LAT-2) in Fayoumi (Fa) and Golden Montazah (GM) chickens. In our previous study we fed Fa and GM layers the same arginine levels and we hatched their eggs to obtain their offspring. Offspring were sexed and sixty female within each strain per each level were selected and randomly divided into 4 replicate with 15 female chicks each. Each group within each strain fed the same dietary Arg level of their parents until 12 wks age. Body weight (BW), body weight gain (BWG), feed intake (FI) and feed conversion (FC) were recorded at 4, 8 and 12 wks of age. Antibody titers against Newcastle disease were measured at 5 days of age to estimate maternal immunity and at 12 wks of age to estimate acquired immunity. Immune organs weighed and their relative percent to live body weight was recorded. Body weight was significantly increased as a result of Arg supplementation for all periods, while BWG was significantly increased during starter period. Neither FI nor FC were significantly affected by Arg treatments during the different periods. Relative liver weight was significantly decreased by Arg supplementation. Maternal and acquired immunity were numerically improved by Arg supplementation. Cationic amino acid transporter-1 mRNA in blood cells was greater in chicks fed 4% Arg than in chicks fed 2%. The Fa strain had higher gene expression of gene (y + LAT-2) than GM strain.

The main objective of this study was to investigate the effect of sodium bentonite (Na-B) (0, 5 and 10 g/kg diet) and chromium picolinate (CrPic) (0, 800 and 1200 µg Cr /kg diet) in the diet on growth performance, the mortality rate; some blood serum constituents, as well as the immune response and economic efficiency of male chicks of local strain Matrouh during the growing period. 540 one-day old male chicks were randomly chosen from a flock reared on the floor and distributed into 9 treatment groups (60 males / each treatment) in a factorial arrange. Feed with Na-B supplementation (5 and 10 g /kg diet) had a significant positive effect (P≤0.05) on body weight (BW), body weight gain (BWG), and feed intake (FI), as well as, serum globulin, triodothyronine hormone (T3), glutathione peroxidase (GPX) and decrease in mortality rate and malonidialdehyde (MDA) values. However, feed conversion ratio (FCR), total antibody responses against SRBCs, total protein, albumin, growth hormone (GH), cholesterol and calcium were insignificantly affected by these treatments, but they gave the highest net return and best economic efficiency (P≤0. 01) compared to their controls at 12 wks of age. Supplementation of 800 or 1200 μg CrPic /kg diet significantly increased BW, BWG and improved FCR, as well as, a titer of SRBCs, serum total protein, albumin, globulin, and GH concentrations. While, the mortality rate and serum cholesterol were significant (P≤0. 05) decreased. However, there were no significant differences among treatments in calcium, T3, MDA and GPX. Supplemented diets with CrPic gave the highest net return and best economic efficiency (P≤0. 01) compared to their controls. Moreover, BW, BWG, FI and FCR, mortality rate, serum globulin and calcium influenced by the interaction between dietary Na-B and CrPic. Whereas, SRBCs, total protein, albumin, GH, cholesterol, T3, MDA and GPX were not significantly influenced by their interaction. It is clear that, supplementing the chick’s diet with both 10 g Na-B and 1200 µg CrPic /kg diet alone or together is recommended for improving most of the growth performance, serum biochemical traits as well as improved immune responses and gave the highest net return and best economic efficiency during the growing period of Matrouh male chicks

This study was conducted to evaluate the effect of rosemary leaves meal as a natural antioxidant in broiler diet on growth performance, blood parameters and the immune response of broiler chickens. A total of 150 Cobb chicks were assigned equally into five treatment groups. The chicks were fed the same basal diet and were submitted to the following dietary treatments: the first group fed a basal diet (control), while the other four groups were fed basal diet supplemented with 0.25, 0.5, 0.75 and 1.0 % of rosemary leaves meal. Chicks fed diet with 0.25% rosemary leaves meal had significantly (P<0.05) greater production performance than the control group. Feed intake and total cost were significantly decreased in chickens fed diet with 0.25% and 0.5% rosemary leaves meal than those fed diet with, 0.75 and 1.0 % of rosemary leaves meal and control group. Rosemary leaves meal had significantly improved the digestibility of crude protein and Ash. Feeding diet with rosemary leaves meal significantly decreased serum urea, creatinine, alanine amino transferase, triglycerides, cholesterol, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) while increased glucose, total protein, triiodothyronine, thyroxine, glutathione, hemoglobin, packed cell volume, red blood cell, white blood cell, lymphocyte, monocytes, mean corpuscular hemoglobin concentration (MCHC), globulin, globulin-γ, bactriocide activity, lymphocyte transformation test (LTT), immunoglobulins (IgY, IgM and IgA), interferon-gamma (IFNγ), interleukin-2 (IL2), interleukin-10 (IL10), phagocytic activity and index compared to control group. Therefore, rosemary leaves meal at 0.25% could be considered as a natural antioxidant in broiler diet, potential growth promoter and immune stimulant for poultry.

ESTIMATION OF ADDITIVE, DOMINANCE AND HERITABILITY OF SOME EGG PRODUCTION TRAITS IN EGYPTIAN LOCAL STRAINS OF CHICKEN
Egg production in poultry shows considerable individual variation over the laying period. Evaluation and selection of Egyptian local strain of chicken had been carried out. The aim of the present study was to estimate additive, dominance, heritability for some egg production traits and to determine the best strain based on multiple egg production traits. The four strains showed that Mandrah strain was ranked first, Doki-4 was ranked second, the strain Inshas was ranked third and El-Salam was ranked last in the performance of some egg production traits. The estimate additive genetic variance accounted a major part of the total genetic variance for sexual maturity, mature egg weight, early egg weight, number of eggs at 90 d of laying, egg mass at 90 d of laying and body weight at sexual maturity. The estimates of dominance genetic variance in these traits was relatively negative and low. The estimated heritability was almost 0.4 for all egg production traits studied. The present results showed clearly that Mandrah local strains of chicken may considered the fitting strains that play an important role in improving egg production.

The objectives of the present study were to verify the effect of using bee pollen and mannan oligosaccharide (MOS) in the feed mixture on semen quality and reduce the effect of lipid peroxidation of V-line rabbit buck semen during Egyptian hot summer season. A total number of 16 mature V line (VL) rabbit bucks 7-8 months-old of proven fertility with an average initial live body weight of 3.52±0.32 kg were classified into four homogeneous treatment groups of 4 bucks. Bucks were kept under a continuous 16 h light/8 h dark photoperiod and the ambient temperature ranged from 27.3 to 30.3 °C and relative humidity ranged from 72.8 to 75.4%. The estimated temperature-humidity index value indicated that during the experimental period rabbit bucks were exposed to severe heat stress. Four experimental diets were formulated to represent four dietary treatments. Bucks in the first treatment group were given the basal diet without supplementation and served as a control group, the second group was given 0.5 % MOS in their diet, while the third and fourth groups included bucks with supplementation of 0.1 and 0.2 % bee pollen in their diets, respectively. Results show that addition of 0.2 % bee pollen resulted insignificant decrease in semen hydrogen ion concentration (pH) as compared with the control and the other experimental feed additives. Addition of MOS, 0.1 and 0.2 % bee pollen significantly increased individual sperm motility, beside, these feed additives numerically increased ejaculate volume and sperm concentration as compared with the control group. Administration of 0.2 % bee pollen insignificantly increased live sperm percentage and mass activity by 13.2 and 27.4 %, respectively. Numerical increase in packed sperm volume (PSV) percentage amounted to 9.8 % due to administration of 0.2 % bee pollen. On the other hand, it was observed that MOS and bee pollen improved testosterone concentration and acrosome action percentage in comparison with the control group. Numerical decrease in seminal plasma MDA concentration, with significant increase in seminal plasma TAC due to MOS and bee pollen supplementation in comparison with the control group. In conclusion, results indicated that MOS and bee pollen improved semen quality and antioxidant status of rabbit bucks during Egyptian summer season.

The present study was carried out to investigate the effect of aqueous extracts of Galega officinalis and Asparagus racemosus on mammary gland development, milk yield and its impact on the productivity of rabbit does. A total number of sixty female V-Line breed rabbits initially aged 10 weeks old, and extended throughout three sequence parities were used in this study. The animals were randomly distributed into five experimental groups (12 does each) .The 1st group was served as control without any supplementations in drinking water, the 2nd and 3rd groups were supplemented with aqueous extracts from aerial parts of Galega officinalis (G. officianalis) of 150 and 300 mg crude extract /kg body weight (BW) respectively. Whereas, the 4th and 5th groups were supplemented with aqueous extract of Asparagus racemosus (A. racemosus) roots of 100 and 200 mg /kg BW respectively of rabbit does. Addition of A. racemosus and G. officinalis led to a significant increase in values of ovarian hormones and surface area of the mammary alveoli compared to control group. Supplementing the rabbit does with both concentrations of G. officinalis in drinking water during rearing period and continuously for full duration of gestation period and first the 21 days of lactation significantly accelerated pubertal mammary gland development, increase milk yield and enhancing productivity of rabbit does compared to control group throughout three sequence parities. The same trend of significant increase was observed with both concentrations of supplementation with A. racemosus during rearing and lactation only. Whereas, supplementing with high level of A. racemosus (200mg/kg BW) during pregnant period significantly increased stillborn at birth .Also, the rabbit does which treated with A. racemosus for throughout the gestation period exhibited higher fetuses resorption rate at slaughter and aberrant embryo spacing within the uterine horns, and therefore smaller litter size of pups in the post-natal studies, with delayed development and increased mortality. In conclusion, water supplementations with aqueous extract from both concentrations of G. officinalis in the drinking water for rabbit does could be recommended to improve pubertal mammary gland development, increase milk yield and enhance productivity of rabbit does. In addition, supplementation with A. racemosus should be avoided in pregnant rabbit does.

This study was designed to investigate the effect of adding combination of Mannan Oligosaccharide and β_Glucans (Agrimos) in diet on productivity and immunity level of does and follow this effect of adding on growing rabbits. At the first experiment: A total of 64 V-Line Does at 5 months of age with an average body weight (3.4± 0.23) Kg divided randomly into 2 treatment groups (n =32 does per group) which received two experimental diets (the basal diet for control group and 2 kg Agrimos /Ton basal diet for treatment group). At the second experiment: From the third parity at 4 week of ages a total number of 108 unsexed weaned V- Line rabbits which produced of each group does (control and treatment does) from the first experiment, was divided into three equal groups each group consisted of 36 rabbits (1st group was fed a basal diet and served as control; 2nd group was fed a basal diet with 1kg Agrimos/ ton and 3rd group was fed a basal diet with 2kg Agrimos/ ton.). Results of the current study are summarized as follows: The does which fed diet contained 2 kg Agrimos /Ton basal diet for treatment group recorded higher litter size at birth (10.41) than its fed basal diet (9.44) with significant differences. Also, the corresponding values of bunny number at weaning were (7.19) higher than its (6.62) but without significant differences. Also, the treated does (2 kg Agrimos /Ton basal diet) resulted in increases of white blood cells (WBC*103), lymphocyte, Mid and IgG comparing with control does (8.98*103, 52.59%, 10.82% and 691.39 mg/ml vs 8.29*103, 44.55%, 10.16% and 597.75 mg/ml, respectively). These results indicated that improving of immunity level for treated doe rabbits by adding Agrimos in diet.Mean of body weight gain from 4 to 10 wks of age for growing rabbits which producing of treated does (1253.53 g/2wks/rabbit) had higher growth than its producing of control does (1076.60 g/2wks /rabbit) with significant differences. Also, the highest body weight gain from 4 to 10 wks of age (1292.00 g/2wks/rabbit) was obtained of fed 1 kg Agrimos/ ton basal diet for growing rabbits producing of treated does during the period of weaning to 10 wks of age. Means of white blood cells (WBC*103), lymphocyte and Mid for growing rabbits which producing of treated does (9.83*103 , 46.49% and 11.53%, respectively) were higher values than its producing of control does (9.15*103, 42.87% and 10.81, respectively). In conclusion, adding Mannan Oligosaccharide and β_Glucans (Agrimos) in rabbits diets significantly improved litter size at birth and immunological status of doe rabbits. And also, body weight gain from 4 wks to 10 wks and immunological status of growing rabbits.
