Rabbits are characterized by meat of good quality and high protein source. It is of importance to study and predict different rabbit characters. A total of 720 data values of three different breeds of rabbits (NewZeland White, Californian, and Rex) and both sexes were used. Discriminant analysis (DA) was used to classify the three rabbit breeds and genders based on the morphological characters (body length (BL), chest circumference (CHC), abdominal circumference (ABDC), thigh circumference (THC), ear length (EL) and ear width (EW)). Data were analyzed using the procedures of DA on SPSS 23 statistical package. The results were that ear width showed a strong participation (0.646) in discriminating the three breeds and explained most of the variance while body length (-0.608) was next in importance as a predictor followed by abdominal circumference (0.531) and the other variables were less contribution. Abdominal circumference is the most significant morphological trait as a discriminating variable (0.695) in discrimination between male and female and explained most of the variance followed by ear width (0.560) then the body length (-0.531). It is found that 59.2 % correct classification of the rabbit breeds using the discriminant functions was achieved and 70.8 % correct classification of the rabbit sexes using the discriminant functions was achieved.","PeriodicalId":7928,"journal":{"name":"alexandria journal of veterinary sciences","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81524514","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}

Substitution of the fresh oil with oxidized oil showed non-significant difference in quail body weight and feed conversion ratio, increased feed intake (FI), non-significantly affected serum lipid profile parameters (P˃ 0.05). Turmeric supplementation at 0.75 % to the fresh or oxidized oil containing diets improved feed efficiency utilization, while reduced the FI compared to control (P< 0.05). Feeding quail on oxidized oil containing diet showed no changes in serum MDA concentration, however reduced serum GPx enzyme (P˃ 0.05) compared to birds fed on fresh oil. Turmeric addition reduced serum concentration of MDA, while increased GPx activity (P˃ 0.05). Increasing turmeric level supplemented to the fresh or oxidized oil was associated with reduced serum lipid profile parameters. Addition of turmeric to the oxidized oil-based diets ameliorated the negative effects on the immune related parameters (phagocytic activity and index, lysosomal activity and WBCs count) especially with 0.5% level. Increasing the turmeric supplementation to the oxidized oil containing diet improved the intestinal morphology and hepatic parenchyma. In conclusion, oxidized oil inclusion in Japanese quail diet (2 %) showed no adverse effects on their performance or intestinal morphology however, negatively affected some immune related parameters which could be ameliorated by turmeric supplementation especially at 0.5% of diet.","PeriodicalId":7928,"journal":{"name":"alexandria journal of veterinary sciences","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84153412","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}

The results revealed that, the mean relative expression of prolactin receptor gene and its fold change level were significantly higher in pure Holstein-Friesian than Montbeliarde×Holstein crossbred at the level of the first three parities. In addition, there is a significant and strong positive correlation between PRLR1 and PRLR3 in pure Holstein-Friesian cattle. Significant negative correlations between PRLR2 and PRLR3, DMY3 and TMY3, were observed in Montbeliarde×Holstein crossbred cows.

Culture and isolation techniques, as well as biochemical tests of milk samples from the four quarters of udders of the 105 apparently healthy cows were carried out. In addition, an in vitro antibacterial sensitivity test was performed for six classes of antibacterial agents. A test of independent assessment (Chi-square test) was used to determine if association existed between the bacterial species collectively isolated and the affected animals (p = 0.716) or quarters (p = <0.000). The study established the presence of subclinical mastitis associated with known pathogens of which Pseudomonas species (67.9%), Staphylococcus aureus (53.6%) and Escherichia coli (14.3%) were most significant in decreasing order of quarter distribution in average percentages. The study further revealed differences in susceptibility of the various quarters and spread of infection. The isolated pathogens were generally most susceptible to the fluoroquinolones while varying degrees of resistance was a finding for other classes of antibacterial used possibly due to their prolonged and indiscriminate use; and this calls for caution by animal health care providers.","PeriodicalId":7928,"journal":{"name":"alexandria journal of veterinary sciences","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134883761","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}

Four hundred and eighty four fish samples of Clarias gariepinus at various developmental stages were randomly selected from fish farms across the three agro – ecological zones in Lagos Stata, Nigeria. The samples collection lasted eighteen months covering both wet and dry season while parasitology and histology examinations were carried out in a laboratory using standard methods.. The wet mounts were prepared for skin and gills. Water quality parameters monitored were pH, water temperature, dissolved oxygen, ammonia, nitrite, iron concentration, alkalinity, hardness and turbidity according to respective manual guidelines. Descriptive statistics such as frequency count, percentages, standard deviation were used to determine the level of prevalence, occurrence and distribution of the parasites. Argulus species (Branchiuran) was the only parasitic crustacean observed in this study with low prevalence and intensity of infection of 1.05% and 2 respectively found on the gills of fingerlings during the rainy season. The histological examination on infected gill revealed no alteration. The water parameters were within the acceptable limit for fish survival. The low prevalence and loads of Argulus sp indicated good management practices which possibly suppress the propagation of the parasites despite the expected influence of optimum temperature and low dissolved oxygen in favour of the parasites. Therefore, good management practices should be encouraged to reduce rate of parasitic infection that often being a primary pathway to secondary infections.","PeriodicalId":7928,"journal":{"name":"alexandria journal of veterinary sciences","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75472574","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}
