Antibiotics are used by veterinarians and producers to treat disease and improve animal production. The federal government, to ensure the safety of the food supply, establishes antibiotic residue tolerances in edible animal tissues and determines the target tissues (e.g., muscle) for residue monitoring. However, when muscle is selected as the target tissue, the federal government does not speci...

The objective of the present study was to study the effect of zinc supplementation (ZnSO4) on sperm morphometry of the Murrah buffalo bulls. Eight apparently healthy, sexually mature and clinically normal Murrah buffalo bulls of similar body weight and age group (nearly 3.0 to 6.5 years) were randomly divided into two groups: control and ING groups. The Diet for both the groups was the same exc...

mineral contents of camel meat were investigated during different periods of fattening. 12 camels (camelus dromedarius), at 12 months of age, were fattened with the same diet during six and nine month periods. feed compositions included 25% alfalfa, 25% straw and 50% concentrate (55% barley, 20% bran, 15% beet pulp, 8% cottonseed meal and 2% salt) were fed under the same conditions. completely ...

Simultaneous exposure to carbon disulfide and noise may have a combined effect on hearing impairment. In this study we investigated hearing loss in 131 men with exposure to noise [80-91 A-weighted decibels; dB(A)] and CS(2) (1.6-20.1 ppm) in a viscose rayon plant. These men were compared with 105 men in the adhesive tape and electronic industries who were exposed to noise only and with 110 men ...

Clostridium perfringens growth from a spore inoculum was investigated in vacuum-packaged, cook-in-bag, marinated chicken breast that included additional 1.0% NaCl. The packages were processed to an internal temperature of 71.1 °C, ice chilled and stored at various temperatures. The total C. perfringens population was determined by plating diluted samples on tryptose–sulfite–cycloserine agar fol...

This study aimed to determine the anti-erosive effects of xylitol, fluoride and a xylitol/fluoride combination used as an additive in an acidic drink or as mouthrinse after enamel was exposed to an acidic drink, in vitro. Human third molars were divided into 7 groups (A-G). Samples from groups A to D were immersed for 5 min in orange juice only (A), orange juice plus either 25% xylitol (B), F(-...

Zinc oxide nanoparticles (ZnO NPs) are an important antimicrobial additive in many industrial applications. However, mass-produced ZnO NPs are ultimately disposed of in the environment, which can threaten soil-dwelling microorganisms that play important roles in biodegradation, nutrient recycling, plant protection, and ecological balance. This study sought to understand how ZnO NPs affect Bacil...

Amorphous indium gallium zinc oxide (a-IGZO) powder was prepared by typical solution-based process and post-annealing process. The sample was used as sensor for detecting C₂H₅OH, H₂, and CO. Gas-sensing performance was found to be highly sensitive to C₂H₅OH gas in a wide range of concentration (0.5-1250 ppm) with the response of 2.0 towards 0.5 ppm and 89.2 towards 1250 ppm. Obvious difference ...

Three experiments were conducted to evaluate the efficacy of phosphorylated mannans (MAN) and pharmacological levels of ZnO on performance and immunity when added to nursery pig diets. Pigs (216 in each experiment), averaging 19 d of age and 6.2, 4.6, and 5.6 kg of BW in Exp. 1, 2, and 3, respectively, were blocked by BW in each experiment, and penned in groups of six. A lymphocyte blastogenesi...
