Effect of a single subcutaneous injection of meloxicam on chronic indicators of pain and inflammatory responses in 2-month-old knife and band-castrated beef calves housed on pasture

• Effects of meloxicam on chronic indicators pain after castration. Cow-calf proximity and home range as novel post-castration. Knife banded calves experienced more acute pain, respectively. Meloxicam did not reduce at the time-points assessed. Proximity have potential to be used pain. One hundred thirty-one 2 mo. old pasture housed Angus cross bull were evaluated for 62 d over two years (Year 1: n = 69, 134.1 ± 20.37 kg BW; Year 2: 62, 118.1 15.49 BW) determine 1) effects a subcutaneous (s.c) injection long term castration 2) use cow-calf Calves randomly assigned treatments using 3 × factorial design including - sham (CT; 47), band (BA; 46) or knife (KN; 38) medication – s.c.

Measurements included performance, scrotal temperature, swelling (WS) healing (WH) scores, sensitivity, collected -1, 6, 13, 20, 34, 48, Suckling, lying, standing walking duration, head-turning, lesion-licking, foot-stamping tail-flick frequencies immediately following up 2-d obtained from 0 14 16.
