The chemical composition of the milk produced indicated increased fat, ash, TS, mineral contents; also there was an increase in viscosity, WHC and antioxidant activity by increasing the added colostrum. On the other hand, samples of the fortified milk revealed a decrease in the rate of mating compared to the control either fresh or during the storage periods. Tissue properties (TPA) are improved by increasing the amount of colostrum added. There was improvement in nutritional and sensory properties by adding colostrum.","PeriodicalId":184675,"journal":{"name":"Journal of Productivity and Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130382216","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}

Res. Station, Gharbeya Governorate, Egypt during 2016 and 2017 growing summer seasons aiming to evaluate effects of transplanting date and foliar feeding with NPK and their interactions on growth, productivity and fruit quality of eggplant (Solanum melongena L,) c.v. Black Beauty. The two tested transplanting dates were summer transplanting on April and late summer on June. While, the three examined foliar feeding levels were spraying with tap water as control, spraying with Potassium-F fertilizer at rate of 3 ml/L or with Raizante fertilizer at rate of 2 ml/L. Foliar spray was done three times throughout growing season. Summer transplanting (April) significantly increased plant height, branches and leaves numbers/ plant and leaf area. Also, leaf percentages of N, P and K as well as total chlorophyll content were increased in April transplanting. Finally, total fruit yield (Ton/ fed) and its quality, expressed as more contents of total soluble solids (%) and total sugars (g/ 100 g D.W.) and less contents of total phenols (mg/ g D.W.) and acidity (%) in fruit tissues, were significantly increased in April transplanting comparing to late summer transplanting (June). Foliar spraying with Potassium-F at 3 ml/L or Raizante at 2 ml/L significantly increased all the above mentioned growth traits and leaf chemical constituents and in turn resulted significant increases in total fruit yield/ fed comparing to unfertilized control plants. Also, spraying Potassium–F or Raizante significantly reduced fruit firmness (kg/ cm 2 ) and fruit contents of total phenols and titratable acidity, at the same time significantly increased total soluble solids, total sugars and K (%) in fruit tissues. Raizante spray was more effective than Potassium-F in enhancing plant growth and fruit yield and its quality.","PeriodicalId":184675,"journal":{"name":"Journal of Productivity and Development","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123663360","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}

Barhi date palms were uniform in vigour and received N as 25 to 100% mineral (inorganic) N from ammonium nitrate (33.5% N), 25 to 100 % organic nitrogen from chicken manure (2.5%N) and the biofertilizer Spirulina platensis algae at 5 to 20 ml/ palm/ year as an attempt for partial replacement of mineral N fertilizers in Barhi date palm orchards to promote yield and fruit quality and to protect our environment from pollution. All growth characteristics, flowering and fruit setting aspects, weight and length of bunch, and yield/ palm were maximized due to supplying the palms with N as 50% inorganic N + 50 % organic manure + the biofertilizer Spirulina platensis algae at 10 ml/ palm/ year. Leaf pigments and nutrients, as well as, both physical and chemical characteristics of the fruits were remarkably improved due to amending Barhi date palms with N as 25% inorganic N + 75% chicken manure + the biofertilizer Spirulina platensis algae at 20 ml / palm /year. The best results with regard to yield of Barhi date palms grown under Upper Egypt conditions were obtained due to supplying the palms with N as 50% inorganic N + 50% chicken manure + the biofertilizer Spirulina platensis algae at 10 ml/ palm/ year . Subjecting the palms with N via 25% inorganic N + 75% chicken manure + the biofertilizer Spirulina platensis algae at 20 ml/ palm / year gave the best results with regard to fruit quality.

The animals were randomly allotted to three experimental groups (12 doe in each). The 1 st group was served as a control and fed basal pelleted diet (Diet A) contained 18% alfalfa hay, represents about 14.3 % of the total crude protein of the diet. The 2 nd and 3 rd groups were fed the same basal diet, but 50 and 75% of alfalfa hay (B and C Diets, respectively) were replaced by moringa hay (leaves+ twigs) on the basis of its contents of protein Conception rate was significantly improved (P < 0.05) in doe rabbits fed Diet C compared with those fed Diet A (control ) or Diet B. Differences in gestation length, litter size at birth, 21 days and at weaning (28 days) and litter weight at 21and 28days among experimental groups were not significant. Litter weight at birth and litter weight gain at all studied ages were insignificantly increased for rabbits fed Diet C compared with those fed the basal diet ( Diet A). Bunny weight at 21 and 28days was insignificantly higher in doe rabbits fed Diet B than those fed Diets A or Diet C. Pre- weaning mortality percentages at all studied ages were similar in all groups. During the 1 st , 2 nd and 3 rd parity, daily and weekly milk yield were insignificantly higher with rabbits fed Diet B or C than those fed the basal diet (control). Milk conversion ratio was insignificantly improved with rabbits fed Diets B or C compared to the control during the 3 rd and 4 th week of lactation. The differences in most doe and offspring traits among the three parities were not significant. However, bunny weight at weaning (28 days) was significantly (P<0.05) increased in the three parities. Milk yield at most stages of lactation insignificantly increased in all parities, except at 1 st week of lactation at which the effect of parity on milk yield was highly significant (P < 0.01). Milk conversion ratio at all stages of lactation insignificantly decreased in all parities. However, the differences in milk conversion ratio were significant (P < 0.05) during the 2 nd and 3 rd week. Conclusively, the results of the present study demonstrated that Moringa oleifera hay (leaves+ twigs) is good unconventional source of protein for feeding doe rabbits and could be added in the diet at levels up to 13.5% to replace about 75% of alfalfa hay without any adverse effects on reproductive and productive traits of New Zealand White doe rabbits.","PeriodicalId":184675,"journal":{"name":"Journal of Productivity and Development","volume":"273 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115664418","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}
