The present study examines the impacts of supplementing yogurt with 1% whey protein concentrate (WPC), Ca-caseinate (Ca-CN) and Spirulina platensis on physiological performance V-line rabbits receiving diets containing (at a dose 5 g/kg body weight/day) different meat quality aspects. results show that fat content was highest (
The animal gastrointestinal tract contains a complex microbiome whose composition ultimately reflects the co-evolution of microorganisms with their host and host’s environment. This study aimed to gain insights into adaptation microbiota local Egyptian cattle three different ecosystems (Upper Egypt, Middle Lower Egypt) distributed across 11 governorates (with an average 12 animals per governorate) using amplicon sequencing. We analyzed from 136 fecal samples through 16S rRNA gene sequencing...
Abstract The supplementation with herbal and medicinal plants to animals showed positive effects on feed digestion, performance animal’s health. Fifteen multiparous Egyptian buffaloes (537 ± 18.1 kg body weight), 7 days after parturition, were randomly assigned 3 treatments in a quintupled × Latin square design 63-day experiment. Each experimental period lasted 21 (15 of adaptation + for measurements samples collection). Buffaloes according their previous milk production, weight parity study...
Buffaloes play a vital role in the Egyptian food security, providing local market by 44% and 39% of milk red meat, respectively.The main objective this study was to compare between buffalo farming systems Upper Egypt (UEg) Delta (DEg).A survey conducted characteristics dairy production two ecologically distinctive zones: UEg DEg.Data were collected throughout interviews with farmers 1811 herds keeping 12450 heads buffaloes.The done from July 2010 January 2011 using comprehensive structured...
The objective of the study was to classify and characterize buffalo farming systems in Delta region Egypt using multivariate statistical analysis approach.A survey conducted on 963 holders dairy Egypt.Data 9665 heads were used.Two techniques, principal component (PCA) followed by cluster (CA) applied all variables survey.A three different groups resulted; 1(C1) :included 34% farms keeping 5132 buffaloes.Itis characterized large average for both farmland area (4.9 feddan) herd size(15.6...
The study aimed to identify the culling reasons of Holstein cows raised in a large commercial herd Egypt with emphasis on performance retained and culled cows. A total 31534 complete lactation records for 10994 calved from 2008 2019 were used. overall rate per was 61.1%. Involuntary represented 92% all cases. included mastitis udder problems (24.2%), reproductive disorders (18.7%), metabolic digestive (13.6%), lameness (13%), endemic diseases (10.8%), low milk yield (8.1%), respiratory...
The study aimed to investigate the association between teat-end hyperkeratosis (THK) and somatic cell count (SCC) assess effect of SCC on milk yield, fat, protein percentages Holstein cows. A total 740 udder quarters 185 cows kept in three commercial herds Egypt were enrolled from May September 2019. Foremilk samples collected for assessing SCC, percentages. On same cows, a digital picture each teat end orifice was taken with camera. Cows’ teats assessed THK classified into two different...
The objectives of the present study were to examine association between brix refractometer% and ELISA assays in assessment colostrum-IgG content studying factors affecting this content. Contents IgG colostrum samples 132 healthy primiparous and multiparous Montbeliard x Holstein cross dairy cows kept Egypt evaluated using assay refractometer%. results showed that contents ranged from 5.96 114.84 mg/mL, with a mean 57.07 mg/mL. Brix% 15% 35%, 23.97%. correlation...
