total number of 180 unsexed 7 days old Hubbard broiler chicks were used in this study to assessment of using scrape crude corn oil (SCCO) as an alternative energy source in broiler diets on growth performance, carcass characteristics and economic efficiency. Chicks were divided randomly into six equal treatments (30 birds each). The experiment lasted from 7 to 40 days-old and contained 6 treatments diets which contained different levels of (SCCO) 0, 20, 40, 60, 80 and 100%, respectively. Results of this experiment showed that, no significant differences between experimental treatments for live body weight (LBW) and daily weight gain (DWG) during the experimental periods. There were no significant differences among treatments for daily feed consumption (DFC) and feed conversion ratio (FCR) during the experimental period. There was no significant effect in carcass traits among treatments. The results showed that the feed price of the diet decreased as the inclusion level of (SCCO) increased as compared to the control group. The relative economic efficiencies of the diets containing 60, 80 and 100% SCCO were higher than other groups. It can be concluded that, scrape crude corn oil can be completely replace corn oil in broiler diets from 7 to 40 days of age without adversely affecting on broiler performance, carcass characteristics and improved relative economic efficiency.
hree composite formulas for children (age 1-3 years) were prepared from boiled rice, wheat, corn, lupine chickpea and cowpea to improve protein quality. The quality was evaluated by determining the proximate chemical composition, physical properties, microbiological and sensory characteristics. Vegetables (sweet potato and carrots), fruits (mango and dates) were also used in three composite formulas. The formula (2) had the highest protein content (22.89%), while formula (3) had the highest fat and fiber content (2.0, 7.7%, respectively). On the other hand formula (2) had the highest protein digestibility (93.62 %). Formula (1), also had the highest Fe content (10.9 mg/100g). While formula 3 had the highest, P content (455 mg/100g) compared with the formula 2 which had the highest Ca and Zn (325.5 and 8.0 mg/100g, respectively). After storage for 15 days at 4 o C the formula (2) showed a minimal total count growth of TBC and Yeast & molud (2 ×10 3). While mold and yeast growth were not detected in any formula. Sensory evaluation indicated that there were significant differences (p <0.05) among the three composite formulas in texture, taste and overall acceptability before and after storage and the formula (1) was the best. Since the prepared formulas are free from artificial colors and preservatives, they are safe, healthy and nutritious for the child to grow in a good health and recover from malnutrition. Therefore, the current study, concluded that these products could be manufactured at home scale as well as on the commercial scale for children.
total number of 210 unsexed 7 days old Hubbard broiler chicks were used in this study to assessment of using cake by-products (CBP) as an alternative energy source in broiler diets on growth performance, carcass characteristics and economic efficiency. Chicks were divided randomly into seven equal treatments (30 birds each) contained 0%, 15%, 30%, 45%, 60%, 75% and 100% replacing yellow corn with CBP. Results of this experiment showed that, chicks' performance including live body weight (LBW), daily weight gain (DWG), daily feed consumption (DFC) and feed conversion ratio (FCR) didn't significantly differ between treatments at different periods and overall period. Carcass traits were not significantly affected among treatments. Economic study indicated that 100% CBP treatment is the most profitable diet among experimental diets. In conclusion, cake by-products (CBP) can be used with broiler chicks' diets without any negative effect on bird performance, carcass traits and improved the relative economic efficiency.
Potato is a cash money crop and plays a crucial role in Egyptian economy, but for its best growth; it demands a good fertilization program as N, P and K. Therefore, this study was conducted to find out the effect of potassium fertilizer levels, in specific, some cultivars on vegetative growth, yield and quality of potato (Solanum tuberosum L.). The investigation was conducted in a private farm during the two successive years of 2015 and 2016 in Maghnine village, Kom Hamada, El-Behera Governorate. Each experiment was laid out as split-plot design, with three replications for both seasons. Three cultivars; Spunta, Provento and Galactica were distributed in the main plots, while the potassium levels; 0,50,75 and 100 kg K 2 O fed -1 were distributed in the sub-plots. The obtained results revealed that there were significant differences in the performance of the tested cultivars, regarding yield and quality parameters especially, cultivar "Galactica" which was found to be more responsive and had high yielding, where it gave the best results in most of the studied parameters. Application of potassium especially at 100 kg K 2 O fed -1 led to the highest values of plant height (cm), plant yield (g), average of tuber weight (g), total tubers yield (ton fed -1), tubers specific gravity, tubers total and reducing sugars content (%) and tubers starch content (%). Thus, it is, recommended that we should introduce potassium fertilizers to optimize productivity of potato in Egypt.
