This review gives an overview on black soldier fly larvae meal (BSFM) as substitute ingredients available to the chicken business, their sustainability, and strategies for promoting them as important protein sources. Traditional sources of protein for chicken feed include soy beans and canola meal. The cost of poultry feeds is largely comprised of energy and protein sources. This is so because in chicken feed, 25–40% of the feed is based on sources of protein, whereas 50–65% of the feed is based on energy. The best strategy to lower the cost of feed is to offer affordable resources or to locate and utilise alternative resources. Insects have attracted a lot of interest as alternative protein sources to replace traditional protein sources used in animal production because of the rising demand for feed protein sources and environmentally friendly production. The nutritional benefits of BSFM, which is distinguished by a balanced amino acid composition and a high concentration of protein, energy, mono- and polyunsaturated fatty acids, have proven to be the most attractive to the feed industry. Previous studies have demonstrated that the dietary low inclusion of BSFM as an alternative to soybean oil has positive effects on energy availability, attributed to improving growth performance and meat quality in species of poultry. These encouraging results suggested that there would be a promising practical application of the BSFM in the formulation of poultry diets.

The present study aimed to evaluate the effect of feed form (pelleted versus mash diets) and probiotic levels on growth performance, carcass traits, some blood parameters and nutrients digestibility of Ross broiler chicks during 42 days experimental period. One hundred and twenty, one day old Ross broiler chicks were randomly distributed into eighth treatments. Each treatment consisted of three replicates of 5 birds each. Both mash and pellet diet groups were subdivided into four treatment groups each. Each fed form supplemented with 0, 1, 1.5 and 2 g probiotic /kg diet, respectively. The obtained data showed that at 3 and 6 weeks of age, broilers fed a pellet diet had considerably higher body weight, weight gain, feed intake, and feed conversion ratio than those fed a mash diet. The ultimate BW and BWG, FI, and FCR of the birds fed the 1g or 1.5g probiotic/kg diets were considerably greater than those fed the 2g probiotic diet and the control diet. The addition of probiotics to the food or feed form of broilers at doses of 1, 1.5, and 2 g/kg had no effect on the carcass and blood parameters. When fed a mash meal instead of a pellet diet, the dry matter and protein digestibility values improved. It can be concluded that fed pellet-diet with the supplementation of 1 and 1.5 g probiotic/kg diet improved productive performance but had no consistent effect on overall carcass traits and blood parameters of broilers chicks.
本试验旨在评价42 d试验期内不同饲料形式(颗粒料与泥料)和益生菌水平对罗斯肉仔鸡生长性能、胴体性状、部分血液指标和营养物质消化率的影响。120只1日龄罗斯肉鸡随机分为8组。每个处理包括3个重复，每个重复5只鸡。土豆泥组和颗粒饲料组再分为4个处理组。每组饲料中分别添加0、1、1.5和2 g益生菌/kg。结果表明，3周龄和6周龄时，颗粒饲粮的体重、增重、采食量和饲料系数均显著高于泥料饲粮。饲粮中添加1g或1.5g益生菌/kg的鸡的最终体重、体增重、FI和FCR均显著高于饲粮中添加2g益生菌和对照组。在肉仔鸡的食物或饲料中添加1、1.5和2 g/kg剂量的益生菌对肉仔鸡的胴体和血液参数没有影响。当饲粮以糊状饲料代替颗粒饲料时，干物质和蛋白质的消化率有所提高。由此可见，饲粮中添加1和1.5 g /kg益生菌可提高肉鸡生产性能，但对肉鸡整体胴体性状和血液参数的影响不一致。

This study examined entrepreneurial intention of undergraduate agriculture students from rural origin at Sohag university- faculty of agriculture. The perceived motivations and obstacles to entrepreneurship among students are also examined. Despite the fact that there have been many studies dealing with students' entrepreneurial intentions, few have specifically addressed the entrepreneurial intentions of agriculture students. The goal of this study is to ascertain the correlations between professional attraction, entrepreneurial capacity, and entrepreneurial experience toward entrepreneurial intention among Sohag University's agriculture students. All variables are measured from developed instrument using 7-point interval scale: professional attraction (6 items) and entrepreneurial capacity (5 items) as the exogenous variable, while entrepreneurial intention (6 items) as endogenous variables. Questionnaires were distributed to 150 students, based on random sampling selected from various races and genders, for the purpose of data collection. The social science statistical application SPSS was used to analyses the data. As a consequence, the hypothesis that professional attraction is positively correlated with entrepreneurial ambition is supported (=0.648, CR=2.324, p0.05). The findings indicated that the majority of students plan to launch their own firm following graduation. They believe that their biggest obstacle to business is a lack of entrepreneurial knowledge.

This study aimed to investigate the effects of green Nano-Copper oxide (Nano-CuO) on growth performance, and serum biochemistry of broiler chickens. A total of 96One-day old broiler chickens were randomly distributed into two equal treatment groups. Treatment groups were fed a control diet or a control diet supplemented with green synthesis of Nano-CuO (8 mg/kg). The feeding trial lasted for 35 days. Each treatment had six replicates with eight birds each. The diets were formulated to meet Ross 308 broiler recommendations. Chicks were full access to feed and water during the experimental period. The brooding temperatures were 38.5, 36.5, and 30.9°C during 1–10, 10–21, and 22– 42 d of age, respectively. The results showed that body weight gain and feed conversion ratio were significantly improved Nano-CuO treated group than non-supplemented group. Furthermore, carcass characteristics were significantly improved (P<0.01) in Nano-CuO compared to control groups. Likewise, supplementation of Nano-CuO significantly improved liver and kidney functions as indicated from serum metabolites. Therefore, it can be concluded that Nano-CuO, achieved sustainable development in broiler production under climate change challenges.

The purpose of this experiment was to examine the effects of probiotic feed additives on the growth performance, nutritional digestibility, and serum metabolic profile of broiler chickens exposed to an aflatoxicosis challenge. A total of 256 Ross 308 broiler chicks were divided into four treatments which included eight replicates and eight birds in each over a 37-day period. Treatments included a negative control (without additions), a positive control with aflatoxin B1 for only first 10 days (AFB1, 40 µg/kg), a negative control with probiotic (0.5 mg/kg)
