The clinical signs and effects on the cardio-respiratory system of Tilest were checked out in weaners. The intramuscular injection of 10 mg/kg BW Tilest caused a rapid immobilisation on an average duration of 33.7 +/- 15 minutes. The muscle relaxation was generally good. Analgesia could not obtained. Heart- and respiratory-rates increased during lateral recumbency. Blood pressure decreased initially. The influence on the arterial blood pH-value and the blood gases are insignificant. In connection with trials to get up the lactate value and the body temperature increased. The CK- and ASAT-activities increased 2 to 6 hours after injection with a wide individual variation. During recovery the pigs were excited and salivated. 相似文献

The in vitro effect and the in vivo influence of recombinant swine IL-4 (rSwIL-4) were characterized in various swine cells and in nursery pigs on LPS-induced endotoxic shock and pro-inflammatory cytokine productions. In in vitro experiment, the rSwIL-4 induced a proliferation of CD4 positive T cells in mitogen-prestimulated peripheral blood mononuclear cell (PBMC). In addition, the rSwIL-4, which was produced from insect cells, promoted the differentiation of monocytes into immature dendritic cells in combination with granulocyte macrophage-colony stimulating factor (GM-CSF). Furthermore, the rSwIL-4 successfully suppressed the LPS-induced secretion of TNF-alpha, IL-1alpha, IL-6, IL-8, and IL-18 from swine alveolar macrophages when rSwIL-4 was treated at the same time with LPS. In in vivo experiment in nursery pigs, subcutaneous pretreatment of rSwIL-4, which was produced from baculovirus expression system, enhanced the severity of respiratory failure with endotoxic shock, and increased the production of TNF-alpha and IL-18 in response to inoculation with LPS. These results indicate that the rSwIL-4 is biologically active in both in vitro and in vivo treatments. Depending on the administration time, pro-inflammatory cytokine productions by IL-4 can cause either inhibitory or stimulatory regulation. 相似文献

The effect of monensin against swine dysentery 总被引:3,自引:0,他引:3
S C Kyriakis 《The British veterinary journal》1989,145(4):373-377
The use of monensin sodium against naturally transmitted swine dysentery was evaluated in 4-week-old piglets, with an average weight of 8 kg, over a period of 112 days. Three treatments were compared using between two and four pens per treatment and 12 pigs per pen. Monensin was administered via the feed, either immediately post weaning to four pens of pigs (T1), or after 12 days (T2, two pens). The T1 group received monensin at the rate of 100 ppm (days 0-56), 50 ppm (days 57-84) and 25 ppm until the end of the trial. In the other group monensin was given at 100 ppm (days 12-84) and at 50 ppm (days 85-112). Unmedicated feed was given to two pens (T3). The continuous administration of monensin from weaning was effective in the control or prevention of swine dysentery. A significant (P less than 0.05) improvement, in comparison with the other two groups, was observed in terms of mortality, diarrhoea score, average daily gain (ADG) and feed conversion ratio (FCR). There was a reduction in mortality, diarrhoea score/days and an improvement in growth performance parameters in pigs treated with monensin after the disease had been established, with ADG and FCR values significantly (P less than 0.05) different compared with the untreated controls. 相似文献

The intention of this study was to develop an intramuscular injectable anesthesia for swine. Therefore the clinical signs of several sedative or anesthetic drugs and their combinations were tested. The combinations of the phencyclidines ketamine and tiletamine with different benzodiazepines were most effective. The phencyclidines induced a rapid immobilisation of sufficient length. The benzodiazepines produced muscle relaxation, prolonged the immobilisation and suppressed the side effects of the phencyclidines like excitation. The analgetic action of the combinations were insufficient. Trials to improve analgesia by supplementation with opiates were only in the combination ketamine/climazolam/levomethadone successful. In other combinations opiates caused postanesthetic excitations with hyperthermia. The trials to improve the analgetic effect by combining tiletamine/zolazepam with imidazolidine-derivatives were only partly successful. But the tiletamine/zolazepam/imidazolidines-combinations caused severe hypothermia and other side effects. Because of postanesthetic excitations, the combination of ketamine with xylazine can not be recommended as a good anesthesia for swine. The action of ketamine with azaperone or different phenothiazine-derivatives was insufficient. 相似文献

The apparent retention and excretion of cations and anions were evaluated in 20 growing pigs to study the mechanisms by which an interaction between dietary K and Cl levels affected growth. All pigs maintained a positive retention of K+ and Cl- regardless of the dietary levels. The K x Cl interaction observed in growth studies previously but not in this study could not be explained by a simple interaction of one ion on the retention of the other. When pooled across dietary Cl levels, an increase in dietary K levels from .10 to .60% resulted in a calculated increase in daily K+ intake of 4.86 meq/kg of BW. Sixty percent (2.99 meq) of the increased K+ intake was excreted in the urine and counterbalanced by a decrease in urine NH4+ (3.06 meq). This decrease in NH4+ excretion could account for essentially all of the increase in N retention (3.51 mmol) observed when dietary K levels were increased from .10 to .60%. Thirty-three percent of the increased K+ intake (1.62 meq) was retained, but the counter ion could not be determined. Retention of Cl- was not changed as dietary K levels were changed. When dietary Cl levels were increased from .03 to .57%, 69% (4.06 meq) of the calculated difference in Cl- intake (5.90 meq) was excreted in the urine, which must have been counterbalanced by a decrease in undetermined organic anions (1.77 meq) and HPO4 = (1.50 meq) excretion, with a tendency for an increased NH4+ (.82 meq) excretion. The counter ions required to balance the increased Cl- retention (1.82 meq) as dietary Cl levels were increased from .03 to .57% could not be identified. Shifts in the retention and urinary excretion of Ca++, Na+, HCO3-, and SO4= did not seem to be quantitatively important in identifying the mechanisms by which dietary K and Cl levels alter growth. Based on these results, we conclude that alterations in growth caused by changes in dietary K and possibly Cl levels are mediated via mechanisms involving renal NH4+ metabolism. 相似文献
