Background: Diarrheagenic E. coli (DEC) strains are a major cause of diarrheal diseases in both developed and developing countries. Healthy asymptomatic animals may be reservoirs of zoonotic DEC, which may enter the food chain via the weak points in hygiene practices.Aim: We investigated the prevalence of DEC along the pig production continuum from farm-to-fork.Methods: A total of 417 samples were collected from specific points along the pig production system, that is, farm, transport, abattoir and food. E. coli was isolated and enumerated using Colilert. Ten isolates from each Quanti-tray were selected randomly and phenotypically identified using eosin methylene blue agar selective media. Real-time polymerase chain reaction (PCR) was used to confirm the species and to classify them into the various diarrheagenic pathotypes. Antimicrobial susceptibility was determined against a panel of 20 antibiotics using the Kirby-Bauer disk diffusion method and EUCAST guideline.Results: The final sample size consisted of 1044 isolates, of which 45.40% (474/1044) were DEC and 73% (762/1044) were multidrug-resistant. Enteroinvasive E. coli (EIEC) was the most predominant DEC at all the sampling sites.Conclusion: The presence of DEC in food animal production environments and food of animal origin could serve as reservoirs for transmitting these bacteria to humans, especially in occupationally exposed workers and via food. Adherence to good hygienic practices along the pig production continuum is essential for mitigating the risk of transmission and infection, and ensuring food safety.

Objective: A 35-day-long trial was conducted to compare the consequences of supplementing cit­ric acid (CA), Spirulina platensis, and their combination as natural substitutes for antibiotic growth promoters (AGP) on the productive performance, dressing percentage, and blood serum metab­olites of broilers.  Materials and Methods: A total of 150-day-old Cobb-500 broiler chicks were randomly assigned to 5 dietary treatment groups, each having 30 chicks in it (10 chicks per replicate cage). The dietary groups were as follows: 1- Control (corn–soybean-based), 2- Control + antibiotic (Enrofloxacin, 10 mg/kg bodyweight), 3- Control + 1% S. platensis, 4- Control + 0.5% CA, and 5- Control + 1% spiru­lina + 0.5% CA. Starting from day 7 up to day 21, antibiotics were administered via water; spirulina and CA were offered via feed.  Results: When compared to the control, all dietary supplements significantly (p < 0.05) improved broiler growth performance. However, dressing characteristics and serum metabolites (serum creatinine, albumin, and uric acid) were not influenced (p > 0.05) by dietary changes, except cholesterol level (p < 0.05). Supplementation with antibiotics, CA, and spirulina produced com­parable results. Among them, the CA-fed group recorded the highest live weight, weight gain, feed intake, improved feed conversion ratio, and the lowest serum cholesterol level (106.5 mg/ dl). The combination group performed better than the control, but not as well as their single supplementations.  Conclusions: CA and S. platensis might both be good candidates as natural alternatives to AGP (Enrofloxacin). But, among them, CA performed better in terms of production performance. J. Adv. Vet. Anim. Res., 9(1): 1–7, March 2022 http://doi.org/10.5455/javar.2022.i562

Objective: This study aimed to evaluate the combination of hairy eggplant (Solanum ferox) and bitter ginger (Zingiber zerumbet) on the production performance and hematological parameters of whiteleg shrimp (Litopenaeus vannamei). Materials and Methods: Four treatments were formulated in the test feed, where P1 (control + commercial vitamin C); P2 (120 ml/l combination of S. ferox and Z. zerumbet); P3 (100 ml/l); and P4 (80 ml/l) 6,000 post-larvae shrimp with an average initial weight of 0.2 gm were randomly stocked in four groups, with three replications per treatment, and 500 were stocked in each pond with a total of 12 pounds. Results: Based on the results, there were significant differences in production performance (survival, absolute weight growth, specific growth rate, and feed conversion ratio). Biologically, the best performance was found in the P3 treatment (100 ml/l). In this treatment, the total number of hemocytes and the number of hyaline hemocytes were much higher, and this was not the case in the control treatment (P1), where the number of semi-granular and granular cells was significantly higher than the treatment group (p &lt; 0.05). Conclusions: This study confirmed that supplementation of 100 ml/l of S. ferox and Z. zerumbet could improve the production performance and hemato-immunological parameters of whiteleg shrimp, with functional potential to be developed in phytobiotic-based commercial diets for shrimp.&nbsp; J.

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. J. Adv. Vet. Anim.

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 applying an automated milk analyzer and the Association of Agricultural Chemists techniques, respectively. 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 &lt; 0.05) total solids and fat where higher (p &gt; 0.05) protein, carbohydrate, and minerals 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 &lt; 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 &gt; 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 &lt; 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. J. Adv. Vet. Anim.

Objective: This study aimed to produce hyperimmune serum against genotype VII Newcastle disease virus (NDV) with several applications. Materials and Methods: Production of hyperimmune serum against genotype VII NDV was performed on eight New Zealand white rabbits divided into four groups. Rabbits were immunized three times on the 1st day, the 14th day, and the 30th day. Blood sampling was carried out on the 8th day after the third immunization. Results: All groups showed the same pattern of hemagglutination inhibition (HI) titer results. HI titers would peak on the 5th or the 9th day after the second immunization, then decrease until the 3rd day after the third immunization, and increase again on the 5th day after the third immunization. Rabbits immunized intravenously showed higher HI titers than the other groups. These results indicate that the intravenous route for hyperimmune serum production against genotype VII Newcastle disease virus greatly affects the immune response result. Conclusions: The production of hyperimmune serum by intravenous immunization three times was able to produce the highest titer of 210 at 38 days. The agar gel precipitation test and the Western blot assay showed that the hyperimmune serum was specific for the Newcastle disease antigen. J. Adv. Vet. Anim.

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 antioxidant 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 coliform 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. J. Adv. Vet.

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: To examine the effects of the salinity level of drinking water on the egg production and quality of Alabio ducks. Materials and Methods: A total of 60 female Alabio ducks, aged 6 months, were subjected to this study. All ducks were kept in stage-type cages (1 m length × 1 m width × 0.5 m height), where each cage was inhabited by 4 ducks for 56 days of experimentation. All ducks were offered a mixed ration ad libitum for laying ducks, according to the nutritional requirements for egg-type ducks. The treatment in this study was drinking water with five stratified salinity levels, namely P0 = freshwater (0% salinity); P1 = water with a salinity of 0.75 practical salinity unit (PSU) (equal to 0.75 g NaCl/l); P2 = water with a salinity of 1.5 PSU (1.5 gm/l); P3 = water with a salinity of 2.5 PSU (2.5 gm/l); and P4 = water with a salinity of 3 PSU (3.0 gm/l). Observations were made on water intake, feed intake, egg production, and egg quality (egg weight, egg shape index density, shell proportion, shell thickness, yolk index, albumen index, and Haugh unit). Results: The results showed that the difference in salinity levels in drinking water from 0.75 PSU to 3 PSU did not affect water intake, feed intake, egg production, or egg quality of Alabio ducks for the first 56 days of the laying period (p &gt; 0.05). Conclusions: It was concluded that Alabio ducks have a good tolerance for drinking water salinity of up to 3 PSU, or equal to 3 gm/l NaCl. J. Adv. Vet. Anim.

Objective: The research was conducted to determine β-carotene and antioxidant activities and screening of phytochemical substances of Moringa oleifera extraction using organic solution. Materials and Methods: 550 gm of M. oliefera leaf flour was macerated. This research was conducted by laboratory experiments using the maceration method. The extraction was performed using three kinds of solvents, which are n-hexane, ethyl acetate, and methanol; for 3 x 24 h, they were concentrated with a rotary evaporator. Then, the flavonoid, phenolic, β-carotene isolation, and antioxidant tests were conducted using the 2,2-diphenyl-1-picrylhydrazyl on each fraction (n-hexane, ethyl acetate, and methanol). Results: The results of weighing each concentrated extract from the maceration process of each fraction (n-hexane, ethyl acetate, and methanol) were 12.67, 35.67, and 49.29 gm, with the total phenolic content (1.4595 ± 0.361, 46.5489 ± 1.832, and 39.74574 ± 0.786) and total flavonoid content of each fraction (3.3056 ± 0.039, 58.6389 ± 2.051, and 48.9056 ± 0.0809), respectively. The antioxidant activity test on the crude extract from the ethyl acetate fractionation showed that the IC50 value was 30.309 mg/ml. The ethyl acetate fraction has a high total phenolic and flavonoid content. The results of the isolation of β-carotene from M. oleifera leaf flour were 0.4798 gm, or equivalent to 0.956% carotenoids. Conclusions: Based on the results of the research, M. oleifera leaves are identified to have a fairly high antioxidant activity, which is 30.309 mg/ml, resulting from the potential compounds in M. oleifera leaves that function as inhibitors of antioxidant activity, which are the groups of phenolic and flavonoid compounds.

Objective: The study was conducted to investigate the gut content and record morphometric and hematological parameters in the common hoopoe (Upupa epops). Materials and Methods: Twenty samples of healthy birds (10 from each sex) were collected from different locations in Okara District, Punjab, Pakistan, from September 2020 to March 2021. Birds were captured live for blood samples and morphometric and gut analyses. Results: It was revealed that the concentrations of different hematological parameters were as follows: hemoglobin, 20.03g/dl; red blood cells, 3.28 × 106/µl; white blood cells, 326.67 × 103/ µl; hematocrit, 56.47%; MCV, 173.33 FL; MCH, 57.4 pg; MCHC, 57.4 pg; PLT, 8.33/µl; and RDW, 8.33/µl. The percentages of neutrophils, lymphocytes, monocytes, and eosinophils were 84.67%, 11.67%, 2.00%, and 1.67%, respectively. The gut content of the common hoopoe mostly consisted of Coleoptera and Acrididae larvae. However, Lepidoptera, Gryllotalpidae, and sand were also recorded, along with seeds of Salvadora persica. Conclusions: There were no significant differences between male and female U. epops in feeding content, total weight of the gut, or weight of the empty gut. Regarding the morphometric parameters, there was a significant difference in both sexes’ wingspan, body length, and body weight. Males were significantly heavier than females. J. Adv. Vet. Anim.
