14C-Fumonisin B(1) (FB(1)) was produced by Fusarium proliferatum M-5991 in modified Myro liquid medium and purified to >95% purity with a specific activity of 1.7 mCi/mmol. Nine male and nine female F344/N rats were each dosed by gavage with 0.69 micromol of (14)C-FB(1), (14)C-hydrolyzed FB(1), or (14)C-FB(1)-fructose/kg body weight. Urinary excretion of (14)C-FB(1) and (14)C-FB(1)-fructose was 0.5% and 4.4% of the total dose, respectively, and was similar between male and female rats. Urinary excretion of (14)C-hydrolyzed HFB(1) was significantly greater (P > 0.05) in female rats as compared with male rats (17.3% vs 12.8% of the total dose, respectively). There were no significant (P > 0.05) differences in biliary excretion of the three fumonisin compounds with a mean of 1. 4% of the dose excreted at 4 h after dosing. Lesser amounts continued to be excreted up to 9.25 h after dosing. Although biliary excretion of the (14)C-FB(1), (14)C-hydrolyzed FB(1), and (14)C-FB(1)-fructose was similar, increased urinary excretion of the (14)C-hydrolyzed FB(1) as compared to (14)C-FB(1) and (14)C-FB(1)-fructose indicated a greater absorption of the hydrolyzed form.
The objective of this study was to determine whether administration of an analgesic to sows immediately after farrowing would allow them to lie more restfully. Sows lying on their pigs, causing them to be "crushed," is a major cause of pig mortality. Most deaths due to crushing occur during the first 3 d postpartum. For modern, lean-type sows, farrowing crates are relatively hard and unforgiving, even though they may be equipped with plastic-coated, expanded metal flooring. Indeed, many sows develop pressure sores on their shoulders, and this may contribute to the sows' discomfort. These sores may cause a sow to change position frequently to alleviate pain, thus increasing its chances of crushing pigs. Sixteen production sows were assigned to either a control group (C, n = 8) with litter size 11.71+/-.78 or an experimental group (B, n = 8) with litter size 11.63+/-1.22. Pigs born to C and B sows weighed 1.60+/-.04 and 1.37+/-.04 kg, respectively. The C sows were given no treatment, whereas the B sows were administered an i.m. injection of butorphanol tartrate at a dose of .15 mg/kg BW every 6 h until 3 d after farrowing. Data were collected on all sows using time-lapse photography (1 frame/.4 s) for a 3-d duration upon the initiation of farrowing. To assess the degree of comfort of each sow, body position changes were recorded when sows switched between lying, sitting, and standing. Data were analyzed by 12-h periods using Wilcoxon-Mann-Whitney equations. During the 72-h period, B sows tended to perform fewer position changes than C sows (P = .10). Specifically, position changes were fewer for B sows from 48 to 72 h postpartum (P<.06). There were no differences in position changes between treatments from 0 to 48 h postpartum (P>.50). There was no difference in the rate of crushing between treatments (C = 5, B = 5). The butorphanol did not seem to affect pig activity or normal behaviors or to create adverse effects, such as diarrhea. Although the sows given butorphanol showed a reduced number of position changes, the dose was intermediate, and a higher dose may have a greater effect. If pig mortality can be decreased, an analgesic protocol that is simple to administer and readily available to producers can be developed. Alternatively, using of more pliable flooring or an increase in sow body fat may allow sows to lie more stationary.
1998) requires that anyone who processes personal information must make sure that the information is 'accurate and up to date'. The use of data validation rules should be considered by hospitals to ensure that a complete dataset is collated. The recording of specialist data should be checked for accuracy by a suitably trained practitioner when the record is being generated.
