A total of 125 unsexed day-old Abor acre chicks were randomly allotted into five treatments, with each treatment having five replicates with five birds per replicate. They were fed a commercial broiler diet for seven weeks of the experiment. Different concentrations of the bovine testicular fluid per liter of drinking water were offered to the experimental birds at free choice, the birds in treatment 1 served as the control and they were offered ordinary drinking water while birds in treatments 2, 3, 4 and 5 were offered 25, 50, 75 and 100 ml of bovine testicular fluid per liter of water, respectively. The feed and water intake of each bird were measured on daily basis, while the average weight of the birds was measured on weekly basis. On day 21 and 49, blood samples were collected from the birds to determine the haematological and serum biochemical indices. Two birds from each replicate were sacrificed on day 49 and sample of ileum were taken for intestinal mucosal examination after processed into permanent slides. The results of the blood indices obtained on days 21 and 49 indicated that the blood parameters were within the normal physiological range for chickens and without evidence of organ damage. The villus height, villus width, crypt depth, crypt height, and mucosa thickness showed that the bovine testicular fluid increased the absorptive capacity of the intestinal mucosa surface area and their growth. It is recommended that bovine testicular fluid at 100 ml/L improved intestinal mucosa development and absorption capacity of broiler chickens and enhanced their growth without deleterious effect on their health status.","PeriodicalId":383871,"journal":{"name":"Journal of Animal Science and Veterinary Medicine","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130322956","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 evaluate the reproductive toxicity and oxidative stress potential of nickel chloride in male guinea pig. Four groups of adult male guinea pigs were orally treated with nickel chloride at doses of 0, 17.50, 26.25 and 52.50 mg/kg bw for 90 days. At the end of the experimental period, all animals were sacrificed, and blood samples and vital organs were collected for different analysis. Treatment of male guinea pigs with 52.50 mg/kg nickel chloride resulted in increased kidney weight and volume and decreased weights of the sex accessory glands (seminal vesicle + prostate + coagulating glands), epididymis and vas deferens. The 52.50 mg/kg dose of nickel chloride decreased (p<0.05) the animal’s sperm mobility, number and viability, while it increased (p<0.05) sperm micro and macrocephalies. Assessment of biochemical parameters of toxicity revealed increase (p<0.05) of serum creatinine and aminotransferases activities in the nickel chloride-exposed guinea pigs (52.50 mg/kg). The nickel chloride (52.50 mg/kg) also promoted oxidative stress, through decrease (p<0.05) of superoxide dismutase and catalase activities, as well as increase (p<0.05) in lipid peroxydation. In addition, histology of testis revealed disrupted germ cell arrangement, decreased concentration of sperms in the lumen of the seminiferous tubules and degraded germinal epithelium in the animals exposed to nickel chloride. In conclusion, results obtained in this study revealed that nickel chloride perturbs male reproductive system and induced oxidative stress.","PeriodicalId":383871,"journal":{"name":"Journal of Animal Science and Veterinary Medicine","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130781160","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 immune response after vaccination is a common problem in poultry industry. Due to this challenge, this experimental study was carried out to evaluate the effects of coconut water on cell mediated and humoral immunity in cockerel chicks. Seventy five day-old cockerel chicks were randomly divided into three groups (A, B and C) and each group contained 25 birds. Group A (control) received ordinary water for 32 days while birds in group B received 100 ml of coconut water/1 L of water for 32 days. Group C received 100 mL of coconut water/1 L of water till day 19 of age and ordinary water from day 20 to day 32 of age. The birds were vaccinated against Newcastle disease (NDV) on day 20. Blood samples were collected on day 19 and 32 to evaluate the leukogram, antibody titer against NDV, total proteins and cytokines. Intestinal samples were also collected for immunoglobulin A analysis following the euthanasia of the birds. Means ± SD of the parameters were calculated and compared for significance differences using one-way ANOVA (p<0.05). A significantly lower total protein and globulin levels were recorded in groups B and C on day 19. Contrarily, there was an increase in total protein and globulin levels in groups B and C, and an increase in monocytes count in group B on day 32. The serum levels of gamma interferon, interleukin 2 and Newcastle disease antibody titre increased significantly in groups B and C on day 32. Immunoglobulin G and A concentrations were not significantly different across the three groups on day 32.

Genomic DNA (gDNA) was extracted from blood samples of Balami, Yankasa, Uda and West African Dwarf (WAD) breeds of sheep. Parts of 5’UTR, intron and exon1 (614bp) was amplified using a primer sequence designed by FastPCR-primer software. The amplicons were digested with restriction enzyme HaeIII and the fragments produced were stained with luminescent dye and run on gel electrophoresis. The genetic structure of the sampled population was investigated after analysis with POPGENE32 software. The HaeIII digested results showed that Myostatin has three polymorphs (AA, AB and BB), controlled by two alleles (A and B), with B having a higher allelic frequency (82.84%) and BB genotype has the highest frequency of 73%. The sampled population showed a deviation from Hardy-Weinberg equilibrium (p<0.05) while the F-statistics results of the Nigerian breeds of sheep showed the breeds are genetically identical (33.40%) within them.

Proximate analysis of fish entrails meal was analysed. Its effects on carcass weight, dressed weight and cuts-up weight were evaluated when used as supplement in the ration of broilers. For the organoleptic evaluation, hedonic scale scorecard was used. A total of 60 respondents evaluated the poultry meat fed with fish entrails meal and each sample were randomly assigned in Completely Randomized Design (CRD) following the four treatments. The treatments were: without fish entrails meal, with 3, 5 and 7% fish entrails meal. Fish entrails meal contained 33.0±0.9% crude protein and 38.4±0.9% crude fat. Carcass quality evaluation revealed that supplementing fish entrails meal significantly influenced the dressed yield (p<0.05), carcass yield (p=0.01), leg weight (p<0.01), and breast weight (p<0.05). Furthermore, hedonic scale scorecard revealed that the colour of carcass were paled but statistically (p<0.05), 7% inclusion rate of fish entrails meal influenced the carcass colour. In terms of economics, broilers fed with 5% fish entrails meal had the highest income over feed cost (43.36 PhP) since it attained highest marketable weight (1,511.11 g/bird).
