The changes in physico-chemical properties of yoghurt containing cress seed mucilage (CM) compared with guar gum (GG) or plain during storage at 5 ± 2 °C for 15 days were evaluated. CM was prepared and added to standardized buffalo's milk (∼3.2% fat ∼15.0% TS) rate 0.025%, 0.05% 0.10% but GG the 0.025% create treatments. latter batch had no GG, serve as a control (C). No significant pH values proteolysis (SN/TN ratio) all samples throughout period observed. yoghurts showed adverse effect on...
The study evaluated replacement of Egyptian berseem clover (BC, Trifolium alexandrinum) with spent rice straw (SRS) Pleurotus ostreatus basidiomycete in diets lactating Baladi goats. Nine homo-parity goats (average BW 23.8±0.4 kg) at 7 d postpartum were used a triplicate 3Ã3 Latin square design 30 experimental periods. Goats fed basal diet containing 0 (Control), 0.25 (SRS25) and 0.45 (SRS45) (w/w, DM basis) SRS. Control was concentrate mixture (1:1 basis). SRS45 had lowered total feed...
Balanites aegyptiaca (L.) Delile (Zygophyllaceae), also known as the desert date, is an edible fruit-producing tree popular for its nutritional and several health benefits.
Foot-and-mouth disease virus (FMDV) serotypes A, O and South African Territories (SAT2) are endemic in Egypt; each is presented by a number of partially related topotypes lineages, depending on their geographical origin. Continuous mutations the emergence new that lead to occasional vaccination failures were frequently recorded, so this study aimed genetically characterize circulating FMD strains Egypt during 2013 2014 outbreaks, focusing amino acids variations VP1 region.A total 51 oral...
Lumpy skin disease (LSD) is an emerging of cattle causing significantly high economic losses. Control LSD depends on the use homologous attenuated virus strains isolated originally from South Africa (the Neethling strain). The belongs to genus Capripoxvirus, which includes sheep pox and goat virus. present study was conducted evaluate safety efficacy a new live vaccine produced by Middle East for Vaccines (MEVAC®) based strain. Tests were performed both in Egypt Vietnam. Safety evaluated...
The effect of using ethanol precipitated cress seed (CSM) and flaxseed (FSM) mucilages in ice cream manufacture compared with commercial Guar Gum (GG) was studied.Ten treatments mixes consisted 10.0% milk fat, 11.5% MSNF 15.0% sucrose were prepared.The CSM, FSM GG added separately at the rates 0.025, 0.05 0.10% (w/w) to create 9 treatments.The latter batch had no polysaccharides' serve as a control.The results showed that CSM significant on pH value, acidity content surface tension mix or...
Foot-and-mouth disease (FMD) is a serious highly contagious viral affecting all cloven-hoofed animals, and outbreaks can have severe economic impact. An inactivated heptavalent oil-adjuvanted FMD vaccine (Aphtovac-7, MEVAC) was prepared from the foot-and-mouth virus (FMDV) strains A-Iran05, A-Africa-IV, O-PanAsia2, O-Manisa, O-EA3, SAT-2 Gharbia, LIB-12. The potency effectiveness were evaluated in three groups of 6- to 8-month-old calves 200 adult dairy cattle under field conditions. All...

Extensive vaccination against Newcastle disease virus (NDV) induced more selective immune pressure from hosts that enhanced the evolutionary process of NDV. Herein, we characterized 13 recently isolated NDV isolates vaccinated chicken flocks during 2014–2017. Sequence analysis F gene showed presence 112RRQKRF117 velogenic cleavage motif in 11 isolates, whereas other two (Ck/ME3/Eg/16 and Ck/ME5/Eg/16) monobasic 112GGRQGRL117. Interestingly, isolate Ck/ME5/Eg/16 100% 99.82% nucleotide...
Abstract This study was conducted to evaluate the dietary effects of chromium methionine (Cr-Meth) chelate on growth performance, oxidative stress parameters, blood biochemistry, and carcass traits broiler chickens. An experiment 34,000 1-day-old straight-run chicks (Indian River; 42.0 ± 0.03) at a commercial farm. The were divided randomly into 3 groups; first group contained 17,000 birds, which used as control, whereas second third groups consisted 7000 10,000 respectively, with 5...
Abstract Plant protein isolates were evaluated and used to replace skim milk powdered in processed cheese blends. The chemical composition of chickpea isolate (CPI), peanut (PPI) sesame (SPI) determined. Functional properties the tested also studied. SPI had minimum emulsion activity index (EAI), while PPI possessed highest value. emulsions formed remained stable after one day, then destroyed at 3rd day. Water absorption capacity (WAC) varried between 196 329 g water/100 protein. water‐oil...
A survey was conducted to determine the prevalence of Aeromonas spp. in 75 random samples (25 each raw cow\'s milk, local plain yoghurt and Domiati cheese) collected from different dairy shops, supermarket street peddlers Diarb Negm Zagazig cities, Sharkia Governorate, Egypt. Investigations involved proteolytic lipolytic activities isolated effect heat- treatment, acidity, pH sodium chloride concentration on bacteria. Prevalence proved 32.0%, 44.0% 20.0% examined cheese with a mean count 9.8...
Cereal and leguminous seeds are considered as major generic dietary source of energy, carbohydrates well proteins in the Mediterranean diet frequently consumed their immature form several regions including Middle East. Hence, current study aimed to assess metabolites' heterogeneity amongst five cereal different species, cultivars, i.e., Triticum aestivum L. (two cultivars), Hordeum vulgare L., Vicia faba Cicer arietinum at maturity stages. Gas chromatography mass-spectrometry (GC-MS)...
The contribution of camels and their products (meat offal) as potential reservoirs foodborne pathogens is far from elucidated. Therefore, the purpose this study was to investigate sources different agents determine antibiotic resistance profile. For reason, one hundred apparently healthy admitted Zagazig abattoir (Sharkia province, Egypt) for slaughtering were studied. Three specimens collected each camel including fresh faeces, raw meat liver which processed presence using standard...
