Objective: This experiment investigated the effect of microencapsulated turmeric by maltodextrin as an amorphous matrix material on the health status of broiler chickens. Materials and Methods: The broilers used were 144 healthy 1-day-old males. The average body weight was 47.8 ± 1.42 gm. The statistical design was based on a completely randomized design with four treatments and six replications. There were six broiler chickens in each experimental unit. The treatments were TM0 = 0 gm/kg of basal feed, TM1 = 1 gm/kg of basal feed, TM2 = 2 gm/kg of basal feed, and TM3 = 3 gm/kg of basal feed. The growth performance, physical traits, internal organs, microbial population, intestinal morphology, hematological parameters, and anti¬oxidant profile were examined. Results: The results reported that microencapsulated turmeric by maltodextrin as an amorphous matrix significantly improved the hematological parameters, growth performance, antioxidant profile, LAB, immune organs, and intestinal morphology. The results also show decreasing coli¬form and pH of the cecum. Conclusions: Dietary addition of maltodextrin microencapsulated turmeric of 3 gm/kg in basal feed can be used as a natural feed additive to improve the health status of broiler chickens.

Objective: The study aimed to determine the effect of Acalypha indica Linn. (AI) root extract and a combination of simvastatin–AI on improving the fatty pancreas in Sprague–Dawley rats induced with a high fructose and cholesterol diet. Materials and Methods: Twenty-four male Sprague–Dawley rats were induced with a high fruc¬tose and cholesterol diet for 4 weeks before being divided into four groups. Each group receiving treatments consisting of simvastatin only, A. indica extracts only, or simvastatin–A. indica extract combination. A histological examination was conducted to determine the effect of each treatment. Also, one-way analysis of variance (ANOVA) and post-hoc Bonferroni test were conducted to assess the comparison of groups from the histological examination. Results: Significant improvement was found in fatty pancreas between rats without therapy and rats treated with simvastatin therapy (p = 0.024, 95% CI: 0.038–0.696), and also between rats without treatment and rats treated with simvastatin–A. indica extract combination therapy (p = 0.000, 95% CI: 0.241–0.873) using one-way ANOVA and the post-hoc Bonferroni test. Conclusions: The results of the combination of simvastatin–A. indica Linn. root extracts treatment showed a synergistic effect on the improvement of fatty pancreas, but further research is needed to find potential adverse effects on the interaction of these two substrates to confirm the safe use of this treatment.

Objective: The objective was to assess the chemical composition, cholesterol, fatty acid (FAs), and amino acid (AAs) profiles of buffalo cheese, butter, and ghee. Materials and Methods: Buffalo milk (raw) was collected from the Bangladesh Agricultural University (BAU) Dairy Farm, BAU, Mymensingh-2202, Bangladesh. Cheese, butter, and ghee were prepared at the Dairy Chemistry and Technology Laboratory, Department of Dairy Science, BAU, Mymensingh, Bangladesh, and subjected to subsequent analyses. The gross nutritional composition and AAs profile of milk were analyzed prior to the manufacture of cheese, butter, and ghee. The gross nutritional composition of milk and dairy products was analyzed by apply¬ing an automated milk analyzer and the Association of Agricultural Chemists techniques, respec¬tively. The cholesterol, FAs, and AAs contents of cheese, butter, and ghee were determined by the Bangladesh Council for Scientific and Industrial Research, Dhaka, Bangladesh. Furthermore, atherogenic and thrombogenic indices were also calculated using reference equations. Results: The results indicated that the buffalo milk is a good source of first-rate nutrients (dry matter: 16.50%, fat: 7.50%, protein: 3.75%). Findings indicated that the butter was significantly rich with (p < 0.05) total solids and fat where higher (p > 0.05) protein, carbohydrate, and miner¬als were found in cheese. The saponification, Reichert-Meissl, Polenski, and Kirschner values of buffalo ghee were found to be 225, 30, 1.2, and 25, respectively. A significant (p < 0.05) variation was found in the cholesterol content of buffalo cheese, butter, and ghee. Butter and ghee had 40.14 and 39.57 mg more cholesterol, respectively, than cheese. The results revealed identical FA profiles except for C24:0 among the three dairy products where the major FA compositions were C4:0, C14:0, C16:0, and C18:0 and C18:1 cis-9. The atherogenicity index and thrombogenicity index of cheese, butter, and ghee were statistically similar (p > 0.05). Butter was found with the most conducive anti-atherogenic and anti-thrombogenic characteristics due to lower saturated and higher polyunsaturated FAs. However, all the AAs concentrations were statistically higher (p < 0.05) in cheese than in butter and ghee. Conclusion: To conclude, buffalo cheese is superior to butter and ghee as regards nutrient density, but consumers can choose other foods based on their choice.

Objective: Most people in Matrouh Governorate consume camel milk as a treatment for many diseases in a raw state to obtain nutritive value. Raw dromedary camel milk can be contaminated by Escherichia coli through fecal matter at any point of milk handling; therefore, it may lose its value and safety specifications. This survey aimed to estimate the incidence of E. coli in fresh camel milk. Materials and Methods: 100 fresh camel milk samples (50 from markets and 50 from farms) were randomly collected from different districts in Matrouh Governorate, Egypt, over 4 months for the detection of E. coli incidence through conventional bacterial isolation, molecular investigation, and gene sequencing. Results: The prevalence rates of E. coli in the examined market and farm raw camel milk based on conventional methods were 24% and 8%, respectively, while those by molecular identification using phoA as an E. coli determinate gene were 4% and 6%, respectively. Moreover, E. coli phoA gene phylogenetic analysis revealed high sequence similarity to E. coli strain CP033158.1 in India and E. coli strain CP047594.1 in China. Antibiotic sensitivity of E. coli isolates showed high suscep¬tibility to norfloxacin (10 μg) and cefoperazone (75 μg). On the other hand, high resistance was found in rifamycin (30 μg) and cefoxitin (30 μg). Conclusion: The results indicate that market camel milk is more contaminated than the farms' own. Additionally, antibiotic resistance is increasing due to antibiotic abuse. [J Adv Vet Anim Res 2022; 9(1.000): 138-143]

Objective: This work investigated the impact of acidified turmeric on growth, blood profile, and gut bacterial counts of broiler chickens stocked in an overcrowding stress condition. Materials and Methods: A total of 285 14-day-old Lohmann broiler strains were distributed to T0 (chicks receiving basal feed raised at a density of 9 chicks/m2), T1 (chicks receiving basal feed raised at 16 chicks/m2), T2 (chicks receiving 1% turmeric powder raised at 16 chicks/m2), and T3 (chicks receiving 1% acidified turmeric powder raised at 16 chicks/m2). Body weight and feed intake were determined weekly. On day 37, blood and intestinal content were collected and analyzed. Results: Body weight was higher while feed conversion ratio was lower in T0 than in other groups. Compared to T0, T1 had a lower thymus weight. Erythrocytes and hematocrits were greater in T0 than in T2 and T3. Hemoglobin was higher in T0 than in T3. Serum superoxide dismutase differed as T0 &lt; T1 &lt; T2. Ileal coliform was higher in T0 than in T1 and T3. Lactic acid bacteria counts were higher in T0 and T1 than in T2 and T3. Conclusions: Acidified turmeric was capable of maintaining the relative weight of the immune organ and ameliorating the oxidative stress of the broiler during overcrowding stress.

Objectives: Streptococcus agalactiae is a zoonotic human and animal pathogen that causes global economic losses in aquaculture and fatal outcomes in Tilapia. This study aimed to identify S. agalactiae isolated from different fish sources intended for human consumption phenotypically and genotypically and to characterize the virulence-associated genes fbsA (fibrinogen-binding protein FbsA), cfb (CAMP factor), and pbp1A/ponA (penicillin-binding protein 1A). Materials and Methods: Three hundred Nile Tilapia fish (Oreochromis niloticus) were collected from different farms and retail shops in Dakahlia and Damietta, Egypt, during the summer of 2020. The samples were examined using routine phenotypic methods, then characterized using polymerase chain reaction (PCR) targeting S. agalactiae-specific dltS gene. All S. agalactiae isolates were examined for the susceptibility to ten antimicrobial agents by the disc diffusion method. The virulence-associated genes (fbsA, cfb, and pbp1A/ponA) were characterized using multiplex-PCR. Results: Streptococcus agalactiae was detected in 7% (n = 21/300) samples. The isolates showed high resistance against ampicillin and erythromycin (20/21; 95%) for each. The most predominant antibiotypes through isolates were P, CN, SXT, CRO, TE, CTX, E, AMP, at 10.5% for each antibiotype. A total of 19 (90.5%) of S. agalactiae isolates showed multi-drug resistance (MDR), and those were recovered from market Tilapia fish. The virulence-associated genes (fbsA, cfb, and pbp1A/ ponA) were identified in the S. agalactiae as 100%, 76%, and 52%, respectively. Conclusions: The MDR S. agalactiae detected in raw Tilapia fish pose a significant health hazard to consumers due to their zoonotic characteristics. [J Adv Vet Anim Res 2022; 9(1.000): 95-103]

Objective: The work aimed to assess the safety and quality of broiler meat in experimental liste¬riosis changes in storage. Materials and Methods: Ross Cobb 500 chickens (40) were divided into 4 groups of 10 animals each. Chickens from three experimental groups were infected by Listeria innocua, Listeria ivanovii, and Listeria monocytogenes. Meat samples were stored for 5 days at 0&#xb0;C–4&#xb0;C. Meat samples were kept in the refrigerator for 3, 4, and 5 days. Microbiological and laboratory indicators of meat freshness were found on these days as well. Results: After the slaughter of chickens with experimental listeriosis, pathological changes in mus¬cles and organs were noted against the background of fattening carcasses with a high slaughter yield. By bacterial contamination, 1 day after slaughter, the meat of chickens of the experimental groups (L. innocua, L. ivanovii, and L. monocytogenes) outperformed the control group by almost 1.9, 13.9, and 24.7 times, respectively (p &lt; 0.05). The same trend is observed for the third, fourth, and fifth days of meat storage. To keep chicken meat fresh for 5 days, only samples from the con¬trol group stayed fresh. Conclusion: According to the total bacterial contamination, the meat of chickens of the groups L. innocua and L. ivanovii was dangerous to human health after 5 and 4 days of storage, respec¬tively. From the first day after the chickens were killed, the meat of chickens that had been infected with L. monocytogenes did not meet the requirements (up to 100 CFU/gm) and was not safe to store or eat.

The same trend is observed for the third, fourth, and fifth days of meat storage. To keep chicken meat fresh for 5 days, only samples from the con¬trol group stayed fresh. Conclusion: According to the total bacterial contamination, the meat of chickens of the groups L. innocua and L. ivanovii was dangerous to human health after 5 and 4 days of storage, respec¬tively. From the first day after the chickens were killed, the meat of chickens that had been infected with L. monocytogenes did not meet the requirements (up to 100 CFU/gm) and was not safe to store or eat.

Objective: The work aimed to assess the safety and quality of broiler meat in experimental listeriosis changes in storage. Materials and Methods: Ross Cobb 500 chickens (40) were divided into 4 groups of 10 animals each. Chickens from three experimental groups were infected by Listeria innocua, Listeria ivanovii, and Listeria monocytogenes. Meat samples were stored for 5 days at 0°C–4°C. Meat samples were kept in the refrigerator for 3, 4, and 5 days. Microbiological and laboratory indicators of meat freshness were found on these days as well. Results: After the slaughter of chickens with experimental listeriosis, pathological changes in muscles and organs were noted against the background of fattening carcasses with a high slaughter yield. By bacterial contamination, 1 day after slaughter, the meat of chickens of the experimental groups (L. innocua, L. ivanovii, and L. monocytogenes) outperformed the control group by almost 1.9, 13.9, and 24.7 times, respectively (p &lt; 0.05). The same trend is observed for the third, fourth, and fifth days of meat storage. To keep chicken meat fresh for 5 days, only samples from the control group stayed fresh. Conclusion: According to the total bacterial contamination, the meat of chickens of the groups L. innocua and L. ivanovii was dangerous to human health after 5 and 4 days of storage, respectively. From the first day after the chickens were killed, the meat of chickens that had been infected with L. monocytogenes did not meet the requirements (up to 100 CFU/gm) and was not safe to store or eat.
