Objective: The objective of the present study was to evaluate heterozygosis in cattle population, and to characterize White Fulani breed by identifying DNA markers considering microsatellites. Materials and Methods: A total of 41 cattle were randomly selected and used for sample (wool) collection for the characterization and identification of phenotypic traits of cattle in Nigeria. The DNA samples from the samples were prepared. Twelve microsatellite primers were used for the microsatellite analysis in the genomic DNA of cattle. The reinforced products were analyzed to determine polymorphic alleles and their frequencies. Results: White Fulani is characterized by a high degree of genetic diversity. The microsatellites have multiple alleles and may show heterozygosity frequencies of at least 70%. White Fulani cows and their F1 descendants form a common cluster, to which the bulls of the Kuru and Red Boro breeds are adjacent. There is a clear differentiation of purebred populations of Tajik zebu-like cattle (Q = 98.7%) and a significant proportion of white Fulani (Q = 81.8%) from Nigeria. The microsatellite analysis of zebu of Nigeria allowed identifying a total of 80 alleles. In the KURU and PAX-KR-BOR rocks, 17 and 19 alleles were identified, respectively. In F1, 51 alleles were detected. Conclusion: White Fulani cattle are characterized by a high degree of genetic diversities. This makes it a highly informative source in genetic analysis. The results can be applied in dealing with the conservation and sustainable applications of genetic resources in the Nigerian cattle population. [J Adv Vet Anim Res 2019; 6(4.000): 474-480]

Objective: This study aims to determine the ameliorative effect of vitamin E (vit E) on histological features and androgen binding protein (ABP) levels in rats induced by allethrin. Materials and Methods: Thirty sexually mature male Wistar rats weighing between 200 and 300 gm, and aging 3 months were taken for this study and were divided into three groups: negative control (NC), positive control (PC), and treatment (T) groups. The PC and T groups were induced by allethrin 12 h per day for 31 days; however, only the T group was given vit E orally at 1 ml/gm body weight (BW) each day for 14 days. The paraffin block method was used to measure tubules diameter, thickness of the seminiferous epithelial layer, and Sertoli cell number. The ABP levels were measured by enzyme-linked immunosorbent assay. Results: The results showed that vit E gave significant effect (p < 0.05) on tubular diameter at NC 123.67 ± 12.77, PC 147.16 ± 10.64, and T 130.08 ± 10.00; tubular epithelial thickness at NC 33.55 ± 3.21, PC 30.02 ± 1.53, and T 32.96 ± 2.81; Sertoli cells number at NC 55.48 ± 5.9, PC 43.84 ± 3.77, and T 53.44 ± 4.26; and ABP levels at NC 72.35 ± 39.06, PC 38, 48 ± 18.78, and T 86.10 ± 35.77, respectively. Conclusion: This study concludes that vit E has an ameliorative effect against the toxic effects of allethrin at testicular histological features and ABP levels.

Objective: To produce, purify, and characterize a polyclonal antibody against acrylamide (anti-AA) for an application to immunochromatographic strip tests for AA. Material and Methods: Polyclonal anti-AA was prepared by injecting N-acryloxysuccinimide-conjugated bovine serum albumin hapten-antigen into New Zealand white rabbits. The antibody was purified using protein A, characterized using sodium dodecyl sulfate-polyacrylamide gel elec¬trophoresis (SDS-PAGE) and conjugated with gold nanoparticles (AuNP). The conjugated antibody was then characterized using UVVis and FTIR spectroscopy and transmission electron microscopy (TEM). Immunochromatographic strip tests were performed using sample pads, conjugated pads, test zones, control zones, and absorbent pads. Strip tests were finally validated using standard AA solutions followed by the application of various concentrations of coffee samples. Results: Using SDS-PAGE, the purified anti-AA antibody was resolved at 50 and 25 kDa, indicat¬ing the presence of heavy and light chains, respectively. The conjugation of anti-AA with AuNP was confirmed using wavelength shifts in UVVis and FTIR spectra, and TEM analyses revealed increased diameters of AuNPs after conjugation. The immunochromatographic strip test was sen-sitive to 1 mgml−1 standard AA. Various concentrations of coffee samples resulted in red color differences in the test zone. High and low coffee concentrations produced thick and thin red lines, respectively. Conclusion: Purified anti-AA can be conjugated with AuNP to produce strip tests for detecting AA in coffee samples. The present immunochromatographic strip tests quantitatively showed increasing intensities of red lines with increasing AA concentrations. [J Adv Vet Anim Res 2019; 6(3.000): 366-375]

Objective: The aim of this study is to inspect the ameliorative effect of avenanthramides (AVA) on CP nephrotoxicity in Sprague-Dawley rats. Materials and Methods: Blood samples were collected for the determination of hematological parameters. Creatinine, blood urea nitrogen (BUN), and tumor necrosis factor-α (TNF-α) were measured in serum. Specimens from both kidneys were taken for histopathological examinations. Results: Administration of AVA resulted in significant decrease in the level of creatinine and TNF-α when compared with CP group. Histopathologically, CP-induced vacuolar degeneration and necro¬sis of the kidney tubules. Administration of AVA ameliorates the histopathological alterations induced by CP. Conclusion: AVA can be considered as a protective agent for kidneys during administration of CP. The protective effect of AVA may be related to the reduction of TNF-α which implicated in the pathogenesis of CP nephrotoxicity. [J Adv Vet Anim Res 2019; 6(4.000): 521-527]

Objective: To explore the effect of glycerol at different concentrations using different extenders on DNA fragmentation and motility of frozen-thawed Kintamani Bali dog spermatozoa. Materials and Methods: Sample was collected from four mature Kintamani Bali dogs. Each ejacu¬late was prepared for cryopreservation with two different semen extenders; egg yolk Tris extender and coconut water-based extender. For each extender, three different glycerol concentrations were used; 4%, 6%, and 8%. Each of the six aliquots was loaded into 0.5 ml cryotube, placed on a styrofoam box 5 cm over liquid nitrogen for 10 min, and immersed in liquid nitrogen up to 8 min. Then, the frozen cryotubes were transferred into liquid nitrogen container. The cryotubes were thawed in a water bath at 38.5°C for 120 sec. After equilibration and thawing, each sample was assessed for motility parameters and for DNA fragmentation. Results: The addition of 6% glycerol to extenders revealed the most effective addition of glycerol on motility and sperm DNA fragmentation after equilibrium and post-thawing. Conclusion: It is concluded that both extenders with the addition of 6% glycerol are safe to be used as an extender in Kintamani Bali dog semen preservation, and DNA fragmentation of Kintamani Bali dog spermatozoa was not influenced by the freezing procedure.
