This study aimed to evaluate the effect of partial uropygialectomy (PU) on carcass criteria and some blood parameters of broilers (ross-308). Two hundred, day-old, broilers were randomly distributed into five experimental groups of 40 chicks in four replicates, 10 chicks each. First group used as control (without PU) while, PU was applied on chicks in the 2 nd (T1), 3 rd (T2), 4 th (T3) and 5 th (T4) groups at 14, 17, 21 and 24 days of age, respectively. On the last day of the experiment carcass characteristics and some blood parameters were studied. Results indicated that the partial uropygialectomy did not have significant effects on percentages of dressed carcass, breast, thigh, drumsticks, back, wings and spleen. The highest abdominal fat% (P<0.05) was recorded for T1 group. Chemical composition of meat was not significantly affected by PU at different ages. Studied blood parameters were not significantly affected by PU, except plasma albumin level which significantly (P<0.05) increased in T3, and cholesterol level which was significantly higher in T4 compared with other groups. From the results of this study, it could be concluded that partial uropygialectomy at 14 days of age for broiler chickens achieved the highest performance and carcass traits

This study aimed to improve the color removal of talodora syrup by using sodium metabisulfite and ammonium persulphate, which have a very important effect in the bleaching process. The behavior of the materials used at different concentrations on Brix and the pH of the syrup was studied, as well as the color removal efficiency. Experiments were carried out at Hawamdia sugar refinery factory, Giza Governorate, in the General Administration for Quality and Control, during September and October 2022. The results showed that the rate of decolorization of the samples increased with the increase the concentration of the additives. The best color removal of the syrup is 60.4% when using Sodium metabisulfite at a concentration of 550 ppm on the processed syrup. While the best color removal of the syrup was 35.2% when ammonium persulphate at a concentration of 800 ppm was added to outlet syrup of talodora when compared to color of outlet syrup of talodora. On the other hand, it became clear that the removal color of the syrup when adding the material at the same concentration to the treated syrup was 70.2%, when compared to the color of the syrup inlet talodora. Through the results obtained, it was clear that ammonium persulfate was better than sodium meta sulfite of its effect on removing the color of syrup .

A Horticultural Station orchard in the Shandaweel region of the Sohag Governorate, Egypt, was the site of this study, which was conducted on mature Aggezi olive cv. (16-year-old) during the 2020 and 2021 growing seasons. This research intends to determine the impact of spraying GA 3 , lemongrass, and moringa leaf extract on the growth and fruiting of Aggezi olive trees, which are uniform in shape and planted in silty clay loam soil using drip irrigation systems. The results demonstrated that all spraying treatments with GA 3 , lemongrass, and moringa extracts enhanced vegetative development, fruit set, yield, and fruit chemical features in comparison to the control. The best treatments comprised 4% extracts of lemongrass or moringa leaves to increase vegetative growth, fruit set, yield, and oil content. Thus, these treatments can be recommended for commercial use under similar conditions.

Consumer demand for natural preservatives in processed meat products has prompted research into alternative options that can maintain health and safety standards. In this study, the chemical composition and antioxidant activity of blueberries ( Vaccinium corymbosum L.) (BB) were investigated, and four beef burger formulas were (control beef burger) (C), a beef burger with 0.01% butylated hydroxytoluene (BHT) (T1), a beef burger with 1% BB (T2), and a beef burger with 1.5% BB (T3). The results revealed that BB contained high levels of total phenolics (435 mg GAE/100g sample, flavonoids (59.76mg Quercetin/ 100g sample), and anthocyanins (173.3mg/ 100g.), making it a promising candidate for use as a natural preservative. Furthermore, incorporating BB into the beef burgers improved all sensory parameters when compared with control, and significantly increased cooking yield, while decreasing cooking loss (p< 0.05). The inclusion of BB also resulted in a clear decrease in the levels of thiobarbituric acid reactive substances (TBARS) and peroxide values (p<0.05), indicating its potential as a functional ingredient with preservative ability during meat product processing. Therefore, the use of blueberries as a natural preservative in meat products is recommended as a sustainable alternative to synthetic preservatives.
消费者对加工肉制品中天然防腐剂的需求促使人们研究能够维持健康和安全标准的替代选择。研究了蓝莓(Vaccinium corymbosum L.) (BB)的化学成分和抗氧化活性，确定了4种牛肉汉堡配方:对照牛肉汉堡(C)、0.01%丁基羟基甲苯(BHT)牛肉汉堡(T1)、1%蓝莓牛肉汉堡(T2)和1.5%蓝莓牛肉汉堡(T3)。结果表明，BB含有高含量的总酚类物质(435 mg GAE/100g样品)、类黄酮(59.76mg槲皮素/100g样品)和花青素(173.3mg/ 100g样品)，是一种很有前景的天然防腐剂。此外，与对照组相比，添加BB改善了牛肉汉堡的所有感官参数，显著提高了蒸煮率，降低了蒸煮损失(p< 0.05)。BB的加入还导致硫代巴比妥酸活性物质(TBARS)水平和过氧化值明显降低(p<0.05)，表明其在肉制品加工过程中具有防腐功能的潜力。因此，建议在肉制品中使用蓝莓作为天然防腐剂，作为合成防腐剂的可持续替代品。
