The sensory evaluation was based on visual, texture and flavor. Syneresis was applied for rheological properties and pH for physical properties. Chemical analysis was applied through moisture, TS, fat and SNF%. Also, titratable acidity% and starch were detected. The microbiological examination for coliforms, fecal coliforms, E. coli , anaerobes and yeasts & molds were counted. The achieved results showed that the sensory evaluation of the pasteurized plain and pasteurized flavored samples was of higher scores than the Baladi samples, however on contrast, syneresis was higher in the Baladi samples. The average values of pH were 4.9, 4.89 and 4.83 for the Baladi, pasteurized plain and pasteurized flavored samples, respectively. For the fat content, the Baladi samples had higher fat%, followed by the pasteurized plain then the pasteurized flavored types. All the examined Baladi samples were starch free, while 70 & 65% of the pasteurized plain and pasteurized flavored types were positive, respectively. The average values of titratable acidity% were 0.91, 0.82 and 0.75, respectively. The microbiological examination cleared that the Baladi samples were more contaminated for coliforms, fecal coliforms and E. coli , while, the pasteurized plain and pasteurized flavored samples were more contaminated for anaerobes. It was found that 85% of the total examined samples were unacceptable according to the Egyptian Standards for their content of yeasts and molds.","PeriodicalId":299161,"journal":{"name":"Assiut Veterinary Medical Journal","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134088924","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}

This study's objective was to investigate the effect of RT on behavior, performance and kidney function of fattening lambs. Twelve male lambs were divided into three groups at random: controls (CON, n = 4): lambs were given one liter of normal saline, (Ts, n = 4): lambs received 1 liter of sheep ruminal juice and (Tc, n = 4): lambs received 1 liter of cattle ruminal juice, once throughout the study. Each lamb was caged in a single pen with alive weight of 20.7 (±1.95) and the experiment lasted six weeks. The instantaneous scan sampling approach was used to record behavioral observations on days 1, 2, 3, 7, 8, 15, 16, 30, 31 and 45 & 46 after rumen fluid transfauntion; production parameters and kidney function were measured every week. Rumen juice transfaunation resulted in a significant decrease in chewing pen fixtures behavior especially in Ts and feed conversion ratio in both (Ts and Tc) at first and second weeks, however a significant increase in body weight in both (Ts and Tc) at third, fifth and sixth week compared to control lambs. There was no significant effect on the serum creatinine and urea levels. In conclusion, the current results indicate that RT has a beneficial effect on fattening lamb’s behavior and performance; therefore it can be used in intensive fattening sheep farms.","PeriodicalId":299161,"journal":{"name":"Assiut Veterinary Medical Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115639898","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}

No efficient treatment plans have been found so far. The neurodevelopmental effects of antiandrogens on developmental milestones were examined in rats following a single intraperitoneal injection of adult pregnant female rats with valproic acid (VPA) (600 mg/kg) on gestation day 12.5. Control females were injected with physiological saline at the same time. The offspring of set 1 (which received physiological saline) was divided into 2 groups (groups 1&2) and the offspring of set 2 (which received VPA) were divided into 5 groups (groups 3-7). Thus, the seven groups were organized as follows: Group 1, the control group in which pups did not receive any treatment. Group 2, pups were given sesame oil vehicle. Group 3 pups did not receive any further treatment. Group 4 in which the pups were given sesame oil. Group 5 in which the pups received 1 mg/day testosterone propionate subcutaneously. Group 6 in which the pups received flutamide 1 mg/kg subcutaneously. Group 7 in which the pups received finasteride 50 mg/kg subcutaneously. Our results demonstrated that VPA-induced retardation in sensorimotor reflexes, but did not affect physical landmarks while antiandrogens improved developmental milestones. In conclusion, our finding confirms that androgen contributes partially towards VPA-induced neurodevelopmental insults.","PeriodicalId":299161,"journal":{"name":"Assiut Veterinary Medical Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128947233","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}

Nano-thymoquinone (nano-TQ) is considered a potent antioxidant that abrogates hepatotoxicity. The aim of the current investigation was to assess the liver toxicity of DOX and the protective effects of nano-TQ on chronic hepatotoxicity in male rats. Sixty rats were divided into four even groups: DOX treated group (group 1) received 3.750 mg/kg b.wt. intraperitoneally at days 10,17,24 and 31 from the beginning of the experiment to make a cumulative dose of 15 mg/kg b.wt., Group (2) received DOX as group 1 beside nano-thymoquinone daily from day one in a dose of 10 mg/kg b.wt. until the end of the experiment, Group (3) received nano-TQ only, group (4) is considered a negative control group. Serum samples were used for estimating oxidative stress markers and liver function enzymes. Liver specimens were used for histopathological and Transmission electron microscopic (TEM) examination. Doxorubicin administration induced an increase in liver enzymes and lipid peroxidation products. Nano-TQ treatment improved those altered parameters. Microscopic examination of the DOX-treated liver sections revealed vascular and parenchymatous alterations as congestion, thrombosis of the blood vessels, vacuolar degeneration, hepatocellular necrosis and fibrosis of the liver. While nano-TQ improved such pathological alteration of the hepatic parenchyma. Transmission electron microscope of the liver revealed infiltration of lymphocyte in the necrotic areas and presence of fat globules in the cytoplasm of the hepatocytes in DOX treated group while TEM revealed a unique finding in DOX and nano-TQ treated group expressed by hypertrophy of Kupffer cells. It could be concluded that nano-TQ has a potent antioxidant effect that protected the liver damage via its free radicals scavenging protection.","PeriodicalId":299161,"journal":{"name":"Assiut Veterinary Medical Journal","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131866815","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}

Poor nutrition can result in various nutritional deficiency disorders such as nutritional deficiency anemia. Nine native breed puppies were screened at regular intervals using a general health physical examination including monitoring their temperature, general inspection, heart and respiratory rate measurements before changing their diet in a controlled experiment. The dogs were kept indoors and their diet was changed from the traditional home cooked food into a commercially available dry diet. Blood samples were also collected for a complete blood count on day one before starting the commercial diet and day 30 at the end of the experiment. The complete blood picture was monitored on set days throughout the experiment and the fecal score was assessed using a fecal scoring system of Royal Canine on day 1 before starting the commercial diet and day 30 at the end of the experiment. There was a significant difference in most blood parameters following the change in diet. Those that were significantly higher were: the total RBCs count, hemoglobin concentration, hematocrit value, mean corpuscular volume, mean corpuscular hemoglobin and the mean corpuscular hemoglobin concentration (p<0.05).

Lipases are one of the most valuable biotechnological enzymes. As a result, studies on lipases have become significantly popular in the field of enzymology in recent years. Several attempts have been made to isolate different bacterial isolates that can produce the lipase enzyme. The current study aims to isolate diverse bacterial isolates from different sources: soil contaminated with oil, animal wounds, and contaminated culture media. A qualitative screening for lipase-producing isolates was conducted using tween 80 agar. The results showed that a total of 124 bacterial isolates were obtained from different sources, including 41 isolates that can produce the lipase enzyme. Upon the lipase activity assay, the 20 highest lipase-producing isolates were identified phenotypically. The best potential lipase producers were further identified using 16S rRNA sequencing as Brevibacillus sp. strain HC1 and Brevibacillus sp. strain HS5, with the accession numbers OR048061 and OR048060, respectively.

Alternative instruments and routes have also been developed. These alternative methods may yield different results. This study aimed to compare different methods in measuring the internal temperature of dogs. Cases referred to the small animal clinic (n=20) for a general health check were included in this study upon confirming their health status. Axillary, tympanic membrane and rectal temperature were measured 30 minutes post-arrival. Rectal temperature (RT) was measured first using a mercury thermometer and a digital thermometer. Axillary temperature (AT) was measured using a digital thermometer. The tympanic membrane temperature (TMT) was measured last using an infrared thermometer. Complete blood count (CBC) profiles, heart rates and respiratory rates of animals were within normal range. The difference between RT and AT ranged from 0.1°C to 1.1°C, whereas that between RT and TMT ranged from 0.03°C to 2.1°C. 40% of temperatures measured by AT and 90% of those measured with TMT differed by more than 0.5°C from those measured by RT. AT and TMT were positively correlated with RT (r = 0.833, P < 0.0001) and (r = 0.475, P = 0.035) respectively. AT and TMT were weakly correlated (r = 0.542, P = 0.014).
