  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 Veterinary drugs are any substances applied to or administered to animals for their therapeutic, prophylactic and diagnostic purposes or modification of physiological function or behavior. They are used throughout the world and more than half of all medicines are prescribed, dispensed or sold improperly. In Ethiopia, also different studies revealed the improper utilization of drugs is common. The use of veterinary drugs in food-producing animals has the potential to generate residues in animal derived products and poses a health hazard to the consumer. The most likely reason for drug residues might be due to improper drug usage and failure to keep the withdrawal period. The residual amount ingested is in small amounts and not necessarily toxic. The major public health significances of drug residue are development of antimicrobial drug resistance, hypersensitivity reaction, carcinogenicity, mutagenicity, tera...
