Although antimicrobial drugs are central to combat disease in modern medicine, the use of these drugs can have undesired consequences for human and animal health. One consequence is the post-therapy excretion of pharmacological agents, such as the elimination of drug residues at very low concentrations in the milk of lactating mammals. Limited information is currently available on the impact fr...

Determination of drug residues in food is of great importance due to their toxicity. Long-term exposure with low level of drug residues could be important, especially in children. Based on document study, oxytetracycline (OTC) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...

antibacterial drugs used in animal might result in deposition of residues in meat, milk and eggs. the presence of antimicrobial residues in animal-originated food is critical problem in many countries over the years. because, drug residues might result in various health hazards, both actual incidence of reactions and potential hazards perceived by the public, the most countries assess residue o...

This study was conducted to determine the chemical composition and nutritive value of sunflower residues silage (SRS) and effects of its substitution with alfalfa hay and corn silage on lactation performance, feed intake, nutrient digestibility and some blood parameters of Mohabadi dairy goats. Four experimental diets were formulated to gradually replace alfalfa hay and corn silage with SRS as ...

Quality of milk plays a key role in its wide consumption but also involvement large series derived products, such as yogurt, cheese, butter, and ice cream. An effective LC-MS/MS method has been validated for the determination 81 different pesticide residues samples. The analyses comprised 44 samples collected during 2019. From all inspected pesticides, only metalaxyl (present 11.36% samples), b...

Polychlorinated biphenyl (PCB) t residues have been found in the milk of cows. In some instances the residue levels exceeded the FDA guideline 0.2 ppm in milk (equivalent to 5.0 ppm in milk, fat), and the milk was removed from the market. The major source of PCB residues in milk is Aroclor 1254 that has been used in coatings for concrete silos. Aroclor 1254 is unaltered in silos, and most of th...

Contamination in milk is more critical as compared to other foods as milk is first diet given to children before they are able to digest solid food. Children have low immunity to combat diseases, so their exposure to pesticide residues is of extreme concern. Lactating animals can be exposed to pesticide residues in several ways such as contaminated feed, contaminated water or direct contact wit...

Livestock is an important sub-sector of agriculture that plays a key role in economy of a country by contributing to GDP (Gross Domestic Product) and in total export. Pakistan is the 5 largest milk producer in the world with a total milk production of about 46.44 billion liters per anum. Almost 68% milk is produced by buffalo and 27% by cow. Pesticides used in agriculture sector may transfer to...

The potential for antibiotic residues in calves from consuming milk containing penicillin G or amoxicillin was investigated. Six calves were fed milk replacer, 6% body weight twice daily, containing 0.293, 2.92, or 5.85 microg of penicillin/ml (ppm) G or 0.25, 1.0, or 2.0 microg of amoxicillin/ml for three consecutive feedings. Urine and blood samples were collected after each feeding. Serum an...
