This experiment was conducted to study the effects of some medicinal plants on bone formation and bone resorption in normal and diabetic rats. The studies included two experiments; the first was in summer while the second was in winter season. Each experiment included 120 adult male albino rats averaged 100±10 gm live body weight. Normal rats were distributed into 4 groups (15 rats each). Group1 fed control diet, Group2 fed garlic 5%, Group3 fed Nigella sativa 5%, Group4 fed garlic 2.5% + Nigella sativa 2.5 %, while four groups included diabetic rats, Group5 (Control), Group6 fed garlic 5 %, Group7 fed Nigella sativa 5% and Group8 fed garlic 2.5% + Nigella sativa 2.5%. Blood samples were collected after 4 and 8 weeks from the start of the experiment and centrifuged at 3000 rpm for 15 minutes to obtain serum. Results show that serum lactic dehydrogenase, alkaline phosphatases, glucose and parathyroid hormone were significantly increased in diabetic rats than normal rats while treatment of diabetic rats with medicinal plants efficiently modify this effect. Serum osteocalcin was significantly decreased in diabetic rats than normal rats. Conclusion, treatment with medicinal plant has a beneficial effect on regulating bone formation and resorption either in normal or diabetic rats.

A trial was carried out on thirty pregnant Ossimi ewes aged 3-4 years, belonging to the Animal Production Research Station at Sids, with live weight ranging between 45 to 50 kg. The animals were divided at randomly into 3 groups of 10 ewes each with almost equal mean live body weight. Animals were given maintenance and production diets according to their average body weight (NRC 1988). Concentrate feed mixture composed of 22% decorated cotton seed cake, 20% molasses, 44% wheat bran, 10% yellow maize, 2.5% ground limestone and 1.5% common salt. Water was provided ad-libitum during the whole experimental period with clover hay and rice straw. The trial started 1st January and ended 1st June 2018 (5 mo. /wool growth) and included 3 groups; Control group; received the basal diet only without any supplements, the first group; was given the basal diet plus 0.23 gm selenoprotein / kg dry matter/ head/day (0.5mg available selenium), the second group; was given the basal diet plus 0.33 gm selenoprotein / kg DM /head /day (0.7mg available selenium). The trial included two periods, the first three months of pregnancy and the last two months of pregnancy. The aim of this study was to study the effect of adding selenium to the diet of pregnant Ossimi ewes on wool growth. Physical and mechanical wool properties were assessed besides estimation of Glutathione peroxidase (GPX) enzyme activity. Results showed that during the first 3 months of pregnancy, there was significant difference (P≤0.05) among groups in FD, SST, ELO % and GPX enzyme activity, while there was no significant difference in STL. But in the last two months of pregnancy there was significant difference (P≤0.05) among groups in STL, FD, SST, ELO % and GPX enzyme activity.

The state directs economic resources to achieve the greatest possible economic and social returns. It is concerned with the implementation of a group of pricing and productivity policies which have a significant role in the performance of the agricultural sector, especially in strategic crops such as wheat and rice, to improve their productivity and to improve the competitive position in the external markets, the method of partial analysis and application of the partial equilibrium model, the policy analysis matrix, the use of financial and economic analysis to assess the production policies have been used. The study aimed at identifying the impact of price and productivity policies adopted by the state on the welfare of producers and consumers, the extent of loss of society and the revenues of the state. The study reached many results, including the following: First, using the partial balance model during the period (2000-2017), it was found that the society lost about 55.7% and 602 million pounds in production. The loss of consumption amounted to about 680.5 and 110.5 million pounds respectively. In terms of the rice crop, the welfare of the producers did not materialize, and the welfare of the rice consumers was achieved. As for the country's revenues, the state's revenues from foreign exchange amounted to LE 990.6 million and LE 24500 million. The government income for the wheat crop equivalent to 2880 million pounds, while the increase in government income for rice crop was estimated at about 20040 million pounds, and wheat and rice producers received support of about 7% and 43% respectively of the world price because they got a price higher than the world price, where the nominal protection coefficient was 1.07, 1.43 Respectively, during the period (2000-2017). Second, the results of the evaluation of the productive policy through the policy matrix in 2017 showed that the producers of wheat and rice crops receive 90% 65% of the value of their production from feddan at the world price of about 14174, 20864 pounds. This means that domestic prices are lower than their global theory and that they bear taxes and the production requirements for both wheat and rice support about 6% and 7% of the world price. The decrease of this subsidy means that the local price is close to the international price, and that there is a comparative advantage for Egypt in producing Wheat and rice crops for the year 2017. The study recommends the following: a) Work to increase the support of production inputs, so that they are available at reasonable prices, in order to ensure minimum agricultural price limits for wheat, commensurate with the international price. b) Preserving the foreign markets of rice, as Egypt has a productive and favorable advantage in the rice crop, contributing to the provision of foreign exchange.

Nowadays, consumer trends towards healthier and low fat products have a significant impact on the deep fat frying industry. The objective of this study was to design a modified deep fat fryer (MDF) to have a smaller surface area relative to height, with made a steam blanketing over the fryer. Different levels of water injection flow rates have been used (0.1, 0.2 and 0.3 ml/20 min. per 1 liter of tested oil), compared with conventional fryers (CDF). Frying was conducted at 170 ± 10 °C into sunflower oil using CDF (H√A = 0.24) and MDF (H√A = 0.8) in batch 8 min. 16 batches every day (eight hrs. /day)for up to 40 hrs (Consecutive five days). The modification was intended to related oil deterioration. Water injection had a dual effect. In comparison with CDF, water injection increased the acidity (expressed as oleic acid) from 0.34 % to 0.97 %, after 40 hrs at 170 ± 10 °C of deep fat frying, and a contrarily, the protective role was observed in all the other quality indices. Significant reductions in TBA values (from 8.9 to 4.81mg malonaldehyde/liter of tested oil), P-anisidine values (from 35.6 to 12.9), TPC contents (from 34.5% to 18.64%), conjugated diene (232 nm) (from 8 to 5.59) and conjugated triene (268 nm) (from 1.9 to 1.33) were recorded in sunflower oil compared with CDF. These quality indices of sunflower oil developed dramatically in the first level of water injection flow rate. Consequently, the first level of water injection had the highest (P≥0.05) inhibitory effect compared with the other levels of water injection. Fatty acid composition of fried oil properties during deep frying CDF and MDF designs were determined. There were significant differences (P≥0.05) of fatty acids composition between the fried oil induces during using of CDF and MDF designs. Total unsaturated fatty acid at MDF design gave the highest values. Also, organoleptic evaluation of fried potato chips by CDF and MDF were evaluated by panelists. Fried potato chips during the first level of water injection flow rate had the highest (P≥0.05) flavor (4), crisp (4.5), greasiness (4.6), and overall acceptability (4.8), compared with fried potato chips during other levels of water injection flow rates and with CDF. Findings suggest that determination of the oil quality indices are good makers of sensory evaluation during deep fat frying. Results indicated the changes in moisture content, oil uptake and shrinkage percentages of potato chips at different levels of water injection compared the control samples. The negative correlation coefficient between oil uptake and moisture content was high (r = -0.915) and linear regression equation for prediction the oil uptake y = 34.1064 – 2.0291X. Also, results suggest that during deep fat frying by MDF design may reduce the thermal deterioration of sunflower oil. Water injection can be applied as a simple method to improve oil quality during deep fat frying.

This study aimed to compare the effect of three different light sources on the growth performance and carcass quality of broiler chickens. Birds were wing banded, individually weighed and randomly assigned to three experimental groups, each including three equal replicates each of 15 chicks. Birds in groups 1, 2 and 3 were exposed to light emitted from incandescent (INC), saving (SAV) and Light Emitting Diodes (LED) lamps, respectively. The studied traits included (BW), (BWG), mortality rate, (FC), (FCR), carcass traits and the economic efficiency. The average BW of broilers in (T2) was significantly higher (P≤0.05) at 2, 4, 5 and 6 weeks than those of birds in (T1) and the (control). The best average of the all experimental period FCR7 g (1.71) was recorded in T2 improving significantly (P≤0.05) than those 1.78 and 1.83 g of (T1) and the (control), respectively. In the same group, (T2) significantly (P≤0.05) increased the percentages of Carcass, Gizzard, Liver, Heart, Spleen, Giblets and dressing than those of the birds in (T1) and the control. Economically, the use of (LED) as lighting source decreased the costs of the lighting program by about 82.87% compared with the (INC) control. The results of this study indicated that the using of (LED) is highly recommended in the broiler production to achieve the best possible profit, especially with the progressive increase in the prices of feed ingredients and power cost.
