The objective of the present study the effects of heat stress on the productive traits are Play an important role in the poultry industry. The experiment was carried out in the farm of the Faculty of Agriculture-Ain Shams University, reared 600 chick of three breeds (Sinai - Fayoumi - Dandrawi) were divided into equal two groups (the treatment was exposed to heat stress on different periods of 3 days - 8 weeks - 16 weeks on temperature of 400c for 4 hours / 3 days. While, the control under environmental conditions. Then, take the body weight in 8, 10,12,14,16 weeks of ages, and body measurements (shank length, tibia length, body depth, keel length, comb and wattle) in three local breeds. The most important results obtained that It could be observed that the effect was high significantly (p<0.0001) heavier in Fayoumi compared to Dandarawi and Sinai in weight body and The results in the body measurements of the parent stock showed The effect on the Fayoumi breed was higher followed by Dandarawi and Sinai, The effect of the rectal temperature and rate respiratory are significant on the breed and the treatment. Concluded that study the effect on productive traits for three local breeds.

A total number of 120 nulliparous APRI and Baladi Black does (60 does for each breed) were mated at 5 months of age at the beginning of the breeding season (during September) to study the effect of re-mating interval after the first parturition on the litter parameters, milk yield per day and reproduction traits. All does were randomly divided into three equal groups according to reproductive rhythm: The 1st group: post partum (PP), the 2nd group: 11 days after parturition (P11), and the 3rd group: Post weaning (PW) .The body weight of P11 does were slightly higher than that of PP or PW groups. The re- mating interval groups during second parity had significant (P<0.05) effects on litter traits at weaning. Litter size and Litter weight at weaning age in PW group were higher significantly (P<0.05) than those in PP and P11 groups. Litter weight at 21 days of age in PW and P11 groups were higher significantly (P<0.05) than those in PP group. The PW group had significant higher litter size at weaning than those in PP group. Daily milk yield (DMY) after second parity was affected significantly by re-mating interval groups in the third and fourth week of suckling period. GL in PP group was higher significantly (P<0.05) comparing with P11 or PW groups. The values of litter size and weight traits were better for APRI does comparing with BB except litter weight at 21 days. The difference in results between the two breeds in daily milk yield showed generally higher trend of daily milk yield for APRI over BB. The Kindling interval and the gestation period were significantly (P<0.05) affected by interaction of re-mating interval group and breed. In conclusion, applying a lengthened period after the first kindling (by more than 10 days or after weaning) had a favorable effect on the does’ production.

Two field experiments were conducted at Sakha Research Station, Cotton Research Institute, Agricultural Research Center at Giza, Egypt during the two summer growing seasons ,2014 and 2015 The aim of the work was to study the effect of the combination among nano-fertilization ,mineral fertilization and organic fertilization on growth, yield and fiber technological properties of Egyptian cotton Giza 94 cultivar.                 The most important results can be summarized as follows: Response of cotton yield and lint properties to mineral N.P.K nano-fertilization the complex treatment contains half dose of both the nano-fertilizer and the bio-organic fertilizer gave the highest reading for plant height (cm), number of fruiting branches per plant, number of open bolls per plant, boll weight (gram), lint percentage, Seed index, Seed cotton yield (Kentar/fed.) , Lint cotton yield  (Kentar/fed.), fiber maturity ratio (MR), upper half mean (UHM)mm, fiber uniformity index (UI), fiber strength  (g/tex), and micronaire value flowed by the treatment 100% nano then the recommended dose of mineral fertilizer NPK. On the other hand, the lowest values for all the above traits, were recorded from the half does of NPK mineral fertilizer in 2014 and 2015 seasons, .While, There were no significant differences between the means of the fiber elongation % due to the treatments applied during the study in 2014 season .It's worthy to mention that, the percentage of fiber elongation had no constant trend due to fertilizer transactions applied on the adopted genotype during` 2015 season, meaning that nano-fertilizer is boosting the fiber elongation percent.

The present experiment was conducted to evaluate the effect of acidifiers on growth performance and immunity of the African catfish C. gariepinus. This experiment was carried out in the wet lab of Fish Production Branch, Department of Animal Production, Faculty of Agriculture, Ain Shams University. A total of 120 fish were selected as healthy catfish which had a uniform size and average weight of 94.93 ± 0.89 g. A thirty of catfish were used in each treatment divided into three replicates as (10 fish/ quadrate tank). Four experimental diets were formulated at 35 % crude protein with different levels of organic acid blend (OAB); diet was supplemented with 0, 2, 4 and 6 ml of organic acid per kilogram diet. Growth parameters, apparent digestibility of crude protein and ether extract were measured. The chemical proximate analysis for whole-body of fish was conducted at the end of the experimental period. Hematological parameters of fish and liver function enzymes were also measured. The fish group fed on 0.6 % organic acids blend showed the highest significance (P < 0.05) increase in total weight gain (438 ± 14.24 g), specific growth rate, best feed conversion ratio, feed efficiency ratio and highest protein efficiency than the rest of experimental groups. The highest apparent digestibility for crude protein were achieved in the third fish group which fed diet supplemented with acidifiers at 4 ml / kg diet and have significant difference (P < 0.05) with other groups. Data obtained in hepatosomatic index % showed no significant difference among different treatment refers to the health status of liver. However, ALAT  and ASAT recorded high values in the higher group of OAB-treated fish indicating that liver could be affected. Hematological parameters were in normal range except for PCV, Hb, RBCs, and WBCs count which were decreased in the high dose of treated fish. Finally, it could be concluded that using of acidifiers as feed additives at lower doses can enhance growth, productivity and immunity of the African catfish (C. gariepinus).

Salinity is a major limiting factor for tomato crop growth and productivity especially in arid and semi arid lands region. Therefore this study was conducted to study the effect of applying sugar beet molasses, priming tomato seedling in saline water and Fe-EDHHA on mitigating salinity negative effects on tomato (Lycopersicon esculentum L.)  hybrid super strain B (salinity sensitive hybrid). Seedlings of tomato hybrid were transplanted on April 4th in both seasons 2014 and 2015 in pots contains washed sandy soil, and irrigated with saline water with EC of  2000, 3000 and 4000 ppm. Beet molasses and Fe – EDHHA were applied at  rates of 200 and 300 kg / fed. for beet molasses and 3 and 4 kg / fed. for Fe – EDHHA. Priming tomato seedlings in saline water treatment was applied at 5 and 6 dS/m for 24 hours.  Data showed that all plant growth aspects such as plant height, leaf area, plant fresh and dry weights were improved under beet molasses, Fe and priming tomato seedlings in saline water treatments compared to none treated plants (control). Yield parameters also followed the same trend. Among treatments, beet molasses at a rate of 200 kg / fed. recorded the highest significant effect in mitigating salinity negative effects. It could be concluded that beet molasses, priming tomato seedling in saline water and Fe – EDHHA treatments were more effective and efficient in mitigating salinity stress on tomato plants.

ve seasons, 2012 and 2013 in a private orchard in Barshom vallage located at El-Kalubia Governorate Egypt. Washington Navel Orange trees (Citrus Sinensis) budded on sour orange rootstock (Citrus aurantium, L.) were 7- years- old and planted at 5 x 5 meters under basin irrigation system. This investigation aimed to study the effect of selenium (Se) levels (0, 20, 40, 80 and 160 ppm)  as foliar spray on growth, yield, fruit quality, leaf mineral content and enzymes activity of Washington Navel orange trees. The obtained data showed that, selenium had a significant promotive effect on growth, yield, fruit quality, leaf mineral content and enzymes activity of Washington Navel orange trees. Results indicated that treatment of Se at 40 ppm gave the highest significant results, whereas, treatment 160 ppm gave the highest fruit selenium content.

Sunflower (Helianthus annuus L.) belongs to the family Asteraceae. The current study used the fluorescent amplified fragment length polymorphism (F-AFLP) technique for evaluating the genetic diversity among 14 sunflower genotypes including eight agronomical traits. Highly significant difference between genotypes was observed for all studied traits (p≤ 0.01). The results of correlation between the studied traits (p≤ 0.05) revealed that positive correlations were observed between most of the traits. Six F-AFLP combination were succeeded in the development of 178 molecular markers within a total of 1007 polymorphic bands, with 97.42% polymorphic percentage. Concerning the molecular markers associated traits, 73 were observed related to morphological and yield component traits. These results may facilitate the simultaneous selection of several economic traits and can thus improve the efficacy of selection based on F-AFLP in the sunflower breeding programs.

Canola (Brassica juncea L.) and mustard (Sinapis alba L.) seed sprout effects on diabetic rats  have no available information and to clarify their effects, both sprouts were investigated in streptozotocin (STZ) induced diabetic and normal rats. Rats were fed on a semi-modified diet containing 10% of canola or mustard sprouted using tap or saline water for sprouting ad-libitum for 6 weeks. STZ showed increases in blood sugar, low density lipoprotein cholesterol (LDL-c), vary low density lipoprotein cholesterol (VLDL-c) and triglycerides (TG). The addition of canola and mustard with or without salinty at 10% to diabetic rats diet as semimodified diet resulted a significant decrease in blood glucose, TG and VLDL-c and data was more pronounced using mustard sprouted or saline water without changes in the HDL-c   parameter. These results showed that canola and mustard especially mustard sprouted in saline water had a hypoglycemic activity in diabetic rats and partly improved lipid metabolism in the experimental rats, with non-toxic to rats in doses given  over 6 weeks period in this study.

Feeding flaxseed to dairy animals improve milk production and reproductive performance. So, the objective of our study was to investigate effect of inclusion flaxseed in Damascus goat's ration on its reproductive performance. Twenty-four Damascus goats (31.40 ±0.50 kg weight and 2-3 years old) were divided into three groups (randomly, eight animals each). The basic diet of  control group (T1) consisted of 56.67% concentrate feed mixture (CFM) and 33.33% Alfalfa hay, while the groups T2 and T3 supplemented with 10% full fat soya, 5% flaxseed + 5% full fat soya and 10% flaxseed, respectively. Inclusion flaxseed in goat’s ration at rate of 5 and 10% resulted in significant increase in all nutrients digestibility, except nitrogen free extract digestibility (NFE) as well as the nutritive values as total digestible nutrients (TDN). Dry matter intakes (DMI) of the different experimental groups were comparable. Goats in T3 recorded the highest does conceived, twinning, conception and kidding rates % as well as total kids born, than other groups (T1 and T2). On the hand T3 recorded the lowest aborted does and barren does (Zero) compared to T1 and T2. Animals of T3 recorded significant higher of total protein, globulin, Albumin and urea concentration than T1 and T2. Concerning lipids profile, the animals of T3 recorded significant lower triglycerides, cholesterol and Low-density lipoprotein concentration than those of T1 and T2. While the animals of T3 recorded significant higher High-density lipoprotein concentration compared to  T2 and T1. The body weight of does is not significantly affected by any of three treatments. In conclusion, flaxseed supplementations in Damascus goat's diets during the gestation period lead to improve total tract digestibility, reduced blood lipids and normalize renal and hepatic functions and improved its reproductive performance, especially those fed on diets containing 10% flaxseed.
