Swine behavioral and physiological response to increasing sodium nitrite oral drench administration and resulting tissue residues

چکیده
Objectives: This study aimed to evaluate the physiological and behavioral responses of pigs administered sodium nitrite, determine an ideal dosing rate by oral drenching nitrite for depopulation events, residue present in ocular fluid skeletal muscle after administration. Materials methods: Four groups 10 market weight (40 total) 1 group sows were used. Each animals received a different drench dose solution (1× [400-441 mg/kg], 2× [800-882 2.5× [1000-1102 3× [1200-1323 mg/kg]) was observed distress behaviors. Two each treatment implanted with monitor measure body temperature, heart rate, activity levels. The apparent best response applied same behaviors monitored. After death confirmed, samples collected from sows. Results: An increased dosage greatly reduced time significant linear relationship. A higher frequency vocalizations most frequent spikes levels lowest group. No correlation found between concentrations. Implications: Oral is viable method swine events. Higher doses have better welfare associations. Ocular anion concentrations do not correlate

Dose-response studies with concurrent administration of piperazine and sodium nitrite to strain A mice.
Male strain A mice were given 0.69-18.75 g piperazine/kg Food and 0.05-2.0 g sodium nitrite (NaN02)/liter drinking water For 20-25 weeks, and were killed 10-13 weeks later. The yield of lung adenomas was significantly greater than in untreated controls when as liHle as 0.69 9 piperazine/kg plus 1.0 9 NaNOdliter, or 6.25 9 piperazine/kg plus 0.25 9 NaN02/liter, were given. A maximum of 30.7 aden...
