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.","PeriodicalId":34040,"journal":{"name":"SVUInternational Journal of Agricultural Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42076406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":34040,"journal":{"name":"SVUInternational Journal of Agricultural Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42855887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":34040,"journal":{"name":"SVUInternational Journal of Agricultural Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49184768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":34040,"journal":{"name":"SVUInternational Journal of Agricultural Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43618987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
