Animals: Eight, 2 month-old Holstein Friesian bull calves.

An in vitro biomechanical comparison of the breaking strength and stiffness of polydioxanone (sizes 2, 7) and polyglactin 910 (sizes 3, 6) in the equine linea alba.

Objective: To determine failure strength, stiffness, and failure mode of 4 suture materials in equine linea alba.

Study Design: Randomized complete block design.

Sample Population: Linea albas collected from 12 adult horses (mean weight, 475 kg; mean age, 10 years).

A romifidine and morphine combination for epidural analgesia of the flank in cattle.

The objective of the study reported here was to determine the onset, duration, and degree of analgesia achieved with a combination of romifidine (50 microg/kg body weight [BW]) and morphine (0.1 mg/kg BW) administered epidurally. Ten adult Holstein Friesen cows were assigned to either a treatment group receiving the romifidine and morphine combination or a control group receiving 0.
