A total number of 270 laying hens + 27 cocks, 24 weeks old were randomly taken to be similar in (1228.0 ±44.0 g) in the study. Birds were randomly divided into nine experimental groups,(30 hens + 3 cocks in each group) and each group was contained three replicates (10 hens+ 1 cock / replicate). The experimental groups involved a3x3factorial arrangement, 3 zinc forms (control, organic zinc and Nano-Zn) and 3 levels of restricted system groups (ad libitum, 90 % and 80 % / hen / day) were fed a balanced basal diet without supplemented zinc as a control or supplemented with 50 mg Nano zinc /Kg diet or 50 mg zinc from zinc methionine /Kg diet, respectively),during the experimental period lasted six month. The obtained results showed that laying hens fed ad libitum / hen /day and 50mg Nano-Zn/Kg diet recorded the highest (P<.01) for egg production( %), egg weight, egg mass, feed conversion / eggs and body weight compared with the control and other groups.

The bucks were assigned to four groups (3 bucks in each group). The first group( control) was fed basal ration composed of 60% concentrate feed mixture (CFM) plus 20% clover hay and 20% rice straw. The 2 nd group was fed basal ration and injected with 50 mg L-carnitine/Kg live body weight twice weekly. The 3 rd group was fed basal ration and injected with 6 mg Coenzyme Q10/kg live body weight twice weekly. The 4 th group was fed basal ration and orally administered daily 25 mg Zinc-methionine. Physical semen characteristics, physiological response parameters and blood biochemical parameters were studied. The obtained results showed that treatment with L-carnitine, Coenzyme Q10 and Zinc-methionine significantly (P<0.01) improved semen quality of Damascus goat bucks. Bucks injected with 50 mg Lcarnitine/Kg live body weight recorded the best values of physical semen characteristics as compared to goats injected with 6 mg Coenzyme Q10/ kg live body weight or those administered 25 mg Zinc-methionine. Hair, skin and rectal temperatures were significantly (P< 0.0%) decreased in goat bucks treated with L-carnitine, Coenzyme Q10 and Zinc-methionine than the control group. Values of pulse rate (beat/min) and respiration rate (beat/min) were not significantly affected by treatment with Lcarnitine, Coenzyme Q10 and Zinc-methionine. Treatment with L-carnitine, Coenzyme Q10 and Zinc-methionine were not significantly affected on most of all blood biochemical parameters with the exception of AST, Testosterone and cortisol levels 672 ABD-ALLAH et al. were significantly (P<0.05 or P < 0.01) affected in the treated groups compared to the control group. Goat bucks injected with 50 mg Lcarnitine recorded the lowest values of AST and the highest values of testosterone as compared to the other groups. However, goat bucks injected with Coenzyme Q10 6 mg/ kg live body weight recorded the highest value of cortisol as compared with the other groups. In conclusion, injection of Damascus goat bucks with L-carnitine at level of 50 mg/Kg body weight or CoQ10 at level of 6 mg/Kg body weight or orally administration of zinc methionine at level of 25 mg/head /day improve their semen quality, maintain their health status and protect them from heat stress during hot summer season of Egypt.","PeriodicalId":184675,"journal":{"name":"Journal of Productivity and Development","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127246413","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}

As a result, it has the potential to deliver useful substances into the human body, such as vitamin C and phenols. The present study was designed to produce orange juice by incorporating chitosan at different proportions (0.08-0.12 g/100 ml juice) into freshly produced orange juice. The sample formulations were further analyzed for changes in their physicochemical including, pH, titratable acidity, total soluble solids, the ratio of total soluble solids to acidity, turbidity, ascorbic acid content, and total phenol content. Microbiological and sensory properties including taste, color, odor, and overall acceptability were determined. As well as their storage stability over a 30-day storage period, the orange juice exhibited improved physicochemical and shelf life properties based on the respective chitosan concentrations used. Hence, the study concluded that chitosan could be used as a natural preservative in the formulation of orange juice.","PeriodicalId":184675,"journal":{"name":"Journal of Productivity and Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131166021","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}

Chinase. The experimental design used in the two growing seasons was randomized completes blocks with three replications. This experiment was included 7 treatments, which were: control, P fertilizer ( P2O5 at 90 kg/fedd, calcium superphosphate ), K fertilizer (K2O at 100 kg /fedd , potassium sulphate ), P2O5 and K2O fertilizer ( 100+90 ), Nano P ( 5ml/l ), Nano K(5 ml/l), and nano P+K (2.5 +2.5 ml/l) The obtained results can be summarized as follows: The treatment of nano potassium + nano phosphorus, followed by the treatment of potassium + phosphorus had a significant effect and recorded the highest values of plant height, fresh and dry weight of whole plant in both growing seasons. While the lowest values of vegetative growth of garlic plants were recorded by the control treatment. There are a significant effect of the treatment of potassium + phosphorus fertilizer application caused a maximum values of average bulb weight, bulb diameter, number of cloves/ bulb and total yield / feddan.
