All carcass traits and cuts also weren’t affected significantly by different levels of silver nanoparticles except breast%. There weren’t significant differences between treatment in all bone physical or chemical measurements except tibia breaking strength where it decreased significantly in all treated groups and ash% where it increased significantly in all treated groups.

The yield of corn crop and plant parts (ears, stems and leaves) were estimated for each sub-plots and calculated per feddan. Whole corn plants were harvested after 92 days of planting at the dough stage of maturity, chopped to 1-1.5 cm of length and ensiled in plastic bags for 35 days.. Representative samples of corn silage were analyzed for composition, fiber fractions and silage quality. Results revealed that high corn plant density showed significantly higher yield of fresh corn crop and TDN (P<0.05) and dry crop and CP and DCP (P<0.01), however, fresh and dry plant weight were lower significantly (P<0.01) compared to low plant density. The percentage of ears was significantly higher (P<0.01), however percentages of stems and leaves were significantly lower (P<0.05) for low plant density compared with high plant density. Low corn plant density revealed significantly higher contents of DM, OM (P<0.05), NFE and NFC (P<0.01) and lower contents of CP, ash (P<0.05), CF, NDF, ADF, ADL, hemicellulose and cellulose (P<0.001) with compared to high corn plant density. The concentrations of total volatile fatty acids (TVFA’s, P<0.05), lactic, propionic, isobutyric, isovaleric and valeric acids were higher, however, pH value and the concentrations of TVFA’s, NH3-N (P<0.05), acetic and butyric acids were lower in low plant density compared to high plant density silage. The DMI and digestibility coefficients of DM, OM, NFE and NFC and TDN value were significantly higher (P<0.05), however, the digestibility coefficients of CP, CF, EE, NDF, ADF, ADL, hemicellulose and cellulose and DCP value were significantly lower (P<0.05) for high plant density compared to low plant density corn silage. Ruminal pH value, the concentration of NH3-N (P<0.05) were lower, however, the concentrations of TVFA’s (P<0.05), propionic, isobutyric, isovaleric and valeric acids were higher with high corn plant density compared to low density corn silage. While, acetic and butyric acids concentrations were nearly similar. There were no significant differences in rent of land, cultivation cost and total cost between low and high plant density.

Current Ca and P recommendation of Cobb 500 broiler was considered as control (T1) for starter and grower phase (100/100). The rest 5 dietary treatments (T2-6) were formulated to meet (100/75-T2), (100/50-T3), (75/75-T4), (75/50T5), (50/50-T6) of Ca and P levels for starter and grower phase. Body weight, body weight gain, feed consumption, feed conversion ratio, carcass traits and economic efficiency were determined to evaluated and examine the effect of reduced levels Ca and P in broiler chicks diet. The results indicated that: Growth performance showed that, all chicks fed the reduced Ca and P diets (T2-6) didn’t show any growth depression. Besides it was interestingly obtained that all reduced Ca and P diets has better body weight gain and fed conversion ratio than control. Carcass traits (carcass% and Total edible parts%) were nonsignificantly different for all treatment group. Economical evaluation study indicated that chicks fed on lower levels of Ca and P below the requirements enhance economic efficiency. The results of the present study showed that the current Ca and P recommendation of Cobb 500 broilers could be lower than real requirement and needs to be updated. So it was concluded that 50% reduction can be possible in dietary Ca and P level of broiler diets, and this wouldn’t cause any impairment in broiler growth and carcass traits. In conclusion: The result indicated that broiler chicks fed on lower levels of Ca and P below the requirements had a positive effect on the economic efficiency of broiler chicks, without any adverse effects characteristics.","PeriodicalId":11538,"journal":{"name":"Egyptian Journal of Nutrition and Feeds","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79926093","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}

Chicks were randomly divided into six equal treatments of three replicates of ten quails each. Results showed that vitamin A affects significantly (P<0.05) on body weight (BW) at 28 and 35days of age. The highest level of vitamin A (40,000 IU) achieved an increase in BW. Also, vitamin D affects significantly (P<0.05) BW at 42 days of age. The highest levels of both vitamin A and D3(40,000 IU vitamin A and 3000 ICU vitamin D3) in treatment 6 achieved the heights BW compared to control treatment. Vitamin A affects significantly (P<0.05) body weight gain (BWG) during the period from 7-28 and 7-42days of age. The highest level of vitamin A (40,000 IU) achieved an increase in BWG.
