  Journal of Dairy & Veterinary Sciences Abstract In species such as the hair, oxidative stress is related to sperm damage during sperm conservation, which affects its fecundity. This research aimed to determine the effect of the addition of melatonin and vitamin E on the levels of Dismutasa-Cu / Zn Superoxide (SOD-Cu / Zn) during the conservation of diluted bristle semen. Seminal maestras of 7 to 18 months old verracos were collected. The optimal parameters are diluted and divided into aliquots: control (with diluent), control with vehicle (diluent and ethanol) and semen with melatonin (1.25 mM) and vitamin E (1 mM. at 16 °C, if enzyme activity (SOD-Cu / Zn), with commercial kit (Cayman®-Chemical Company Ann Arbor, MI, USA) and Hypo-osmotic Test (HOST +), to evaluate the integrity of Plasma membrane Results were analyzed by ANOVA, with SPSS 15.0 statistical package for Windows with p≤0.05 If SOD-Cu / Zn was observed in melatonin-based women, but significantly (p <0.05) high...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract African horse sickness (AHS) is an infectious and non-contagious disease of equidae transmitted mainly by Culicoides species. The disease is caused by AHS virus (AHSV), a linear dsRNA virus, within the genus Orbivirus of the Reoviridae family, having 9 different serotypes. Kenya has experience death of horses due to AHS, despite vaccination. The vaccine used has two parts, administered 2-3 weeks apart. Part 1 is trivalent, while part 2 is tetravalent, however, it lacks serotypes 5 and 9. The objective of this study was to determine AHSV serotypes circulating in Kenya to inform the best vaccine and control strategies for AHS. Samples were collected from 37 horses (24 dead, 13 live) in different regions in Kenya including Nanyuki (n=14), Nairobi (n=6), Nakuru/Naivasha (n=14) and Kisumu (n=3). Majority of horses showed different clinical signs characteristic of the acute pulmonary form, however, some showed the...
