Therein, we investigated the effects of varying photoperiodic treatments on morpho-biometry of the excurrent duct system of helmeted guinea fowl (Numida meleagris). A total of twenty-one (21) apparently healthy sexually-matured helmeted guinea fowls were randomly assigned into three (3) photoperiodic regimes; mainly [Group I: Short daylight (SD; 8 HL (Hour of light, Group II: Moderate daylight (MD; 12 HL) and Group III: Long daylight (LD; 16 HL)] of seven birds per group (n=7). After 8 weeks of experimentation, the excurrent ducts were excised and freed of all adhering connective tissues for gross-morphological and morphometric evaluations. The bio-morphometric data (weight and diameter) were significantly increased (p< 0.05) in the epididymis and ductus deferens of guinea fowl exposed to 16 HL, as compared to other treatments. However, no significant (p> 0.05) effect was observed in body weight and length of the excurrent ducts regardless of photoperiod. The observed changes in weight and diameter of the epididymis and ductus deferens of helmeted guinea fowl are thus a consequence of the stimulatory effects of long photoperiod exposure to reproductive activity. Thus, these findings would therefore be useful to guinea fowl breeders in designing appropriate intervention programs necessary to improve their reproduction efficacy and to preserve this species. \u0000 ","PeriodicalId":21527,"journal":{"name":"Sahel Journal of Veterinary Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86265808","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 was designed to document the reproductive tract morphometric dimensions and milt characteristics of wild C. gariepinus during spawning and non-spawning seasons in Lake Alau, Maiduguri, Nigeria. Sixty male brood stocks were used comprising thirty each for spawning and non-spawning seasons. The reproductive tracts were removed and their dimensions measured. The milt samples were collected, pooled and evaluated. Results of the study showed that the body weight, sperm concentration and testicular indices differed significantly (p˂0.05) between the two seasons of evaluation. In addition, a positive correlation (p˂ 0.05) between body weight of fish and milt volume (r = 0.656 and r = 0.646) was also observed in both seasons. It was concluded that the left testis of C. gariepinus is heavier, longer and thicker than the right. Nonetheless, the C. gariepinus had larger body weights and higher spermatozoa concentration in spawning season than in non-spawning season; those with larger body weights had higher volume of milt than those with lower body weights.","PeriodicalId":21527,"journal":{"name":"Sahel Journal of Veterinary Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80257589","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 total number of cows slaughtered in Hadeja abattoir and the fetal wastage were evaluated. Variation in the number of fetal wastages during dry season and rainy season were determined. Economic implications of fetal wastage were evaluated. The results revealed the number of fetuses wasted were 3,763 within a six-year period. The highest number of fetal wastages 2777 (73.8 %/) were recorded in the dry season with (P < 0.05), compared to the number of fetal wastages 986 (26.2 %) recorded in the rainy season. The financial losses due to fetal wastages was estimated at ₦2,162,160,000 with an annual loss of ₦ 360,360,000. The yearly average fetal wastage across the study period was 627 (16.7 %). Large number of fetal wastages were recorded during the dry season with signiﬁcant economic losses. Hence, effective ante mortem inspection and pregnancy diagnosis in cows is necessary in order to avert this problem at the abattoir.

Bioremediation/biodegradation can be considered as an effective aid to clean up oil spills, aside from conventional methods that are uneconomical and produce residues that harm the surrounding biota. There are an estimated over 250 mechanic shops with more than 5000 technicians in Maiduguri. Mechanics working therein frequently spill oil which is a potent source of immunotoxicants and carcinogenic to humans and animals. The aim of this study was to screen for petrophilic bacterial isolates from engine oil contaminated soil, that can utilize crude oil as sole source of carbon for growth in Maiduguri Metropolis. Ten isolates from engine oil contaminated soils in Bola and Tashan Kano areas of Borno State were obtained. The bacteria were individually cultured in Bushnell Haas Mineral Salt Medium devoid of carbon source except for crude oil for 21 days at 370C. Bacterial growth from visible increased turbidity was enumerated by CFU/g on nutrient agar. Pseudomonas sp. isolate exhibited relatively higher ability to grow on crude oil with TNTC followed by Bacillus sp., 6.7×104, Arthrobacter sp.,6.5×104, Flavobacterium sp.,6.2×104, Pseudomonas sp., 6×104, Nocardia sp.,5.9×104, Acinetobacter sp., 5×104, Bacillus sp., 5×104.
