Management of inappetant sheep during export by sea     

RT NORRIS  CL McDONALD  RB RICHARDS  MW HYDER  SP GITTINS  GJ NORMAN 《Australian veterinary journal》1990,67(7):244-247

In the first of 2 experiments, a simulated voyage was conducted to examine the effects of various treatments on bodyweight change and feeding frequency of inappetant sheep at the end of lot-feeding (non-feeders). The treatments, applied during simulated shipping, were: normal quantities of feed and length of troughs; extra trough length; extra feed. Adult Merino wethers (n = 108) were used in each treatment. A voyage to the Middle East was then conducted to establish whether shipboard mortality could be reduced by separating non-feeders (n = 305) from feeders (n = 5,620) late in the feedlot hase and housing the groups separately aboard ship. A control group of non-feeders (n = 215) mixed with feeders (n = 5,732) was used for comparison. Bars (marker bars), containing a coloured dye, were attached to feed troughs to mark sheep that fed. Most non-feeders (82%) began eating when placed in shipping pens in both studies. However, there was no significant difference in percentage of sheep that fed between non-feeders given extra trough length or extra feed compared with non-feeders given standard management at any stage of simulated shipping. There was no significant difference in mean bodyweights between treatment groups on days 1, 8 and 15 of simulated shipping. Differences in bodyweight on d 22 were probably associated with different levels of gut fill. Death rates were not significantly different in separated and control groups (1.1%, 0.9%, P = 0.6) in the voyage of 14 d to the Middle East.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Impacts of Air Pollution Control Strategies in Kentucky     

FRANK A. SCOTT  MARK C. BERGER  GLENN C. BLOMQUIST 《Growth and change》1988,19(2):40-55

The purpose of this paper is to estimate the impacts of air pollution control strategies for one state, Kentucky, on its own economy. Effects of the Clean Air Act are estimated, but the emphasis is on scenarios for compliance with pending acid rain legislation. The most restrictive scenario involves a 478,000 ton per year reduction in SO₂. Based on elasticity and engineering estimates, we project shifts from high-sulfur Western Kentucky coal to low-sulfur Eastern Kentucky coal, higher electric utility rates and manufacturing costs, and lower manufacturing employment. Impacts are always less than 6 percent of 1985 levels.  相似文献   

Controlling microbial contamination on beef and lamb meat during processing   总被引：2，自引：0，他引：2

SUMMARY The microbiological quality of carcases, meat and environmental surfaces was evaluated in commercial boning rooms processing beef and lamb. There was considerable variation in the level of microbial contamination on both carcases and meat, with counts ranging from less than 20 to 10⁸/cm² on carcases and to 2 times 10⁷/cm² on meat. The level of microbial contamination on meat was influenced by the level of carcase contamination at boning and by the boning process itself. Carcase contamination was the major determinant of microbiological quality, as more than 70% of carcases had microbial counts greater than 10³/cm². Cutting boards were a major source for microbial dissemination during boning, particularly when carcase counts were less than 10³/cm². If carcases were heavily contaminated, the contamination of processing surfaces was irrelevant in determining microbial loads on meat. Where carcase contamination was at low to moderate levels, the contribution of the boning process to the contamination on meat assumed increased significance. Under these conditions, improved sanitation of cutting surfaces in the boning room resulted in a significant reduction in microbial contamination on the surface of meat. These results can form the basis for ensuring that improvements made in carcase management before boning, to improve microbiological quality, will be preserved through attention to cutting board hygiene during boning.  相似文献   

Metoclopramide Reversal of Decreased Gastrointestinal Myoelectric and Contractile Activity in a Model of Canine Postoperative Ileus   总被引：2，自引：0，他引：2  

GLENN M. GRAVES DVM  MS    JAMES L. BECHT DVM  MS  CLARENCE A. RAWLINGS DVM  PhD  DiplomateACVSA 《Veterinary surgery : VS》1989,18(1):27-33

Postoperative ileus is characterized by decreased gastrointestinal myoelectric activity and motility. Metoclopramide was used to treat experimentally induced postoperative ileus in six dogs. Contractile activity was monitored by extraluminal strain gages on the pyloric antrum and proximal segment of the duodenum, and myoelectric activity was measured by recording bipolar electromyograms (EMGs) at the pyloric antrum, pyloric canal, proximal segment of the duodenum, proximal and distal parts of the jejunum, and ileum. Measurements were obtained from animals without ileus (baseline) and those with ileus that were either untreated or treated with metoclopramide. Adynamic ileus was induced by rubbing a 50 cm segment of jejunum with a dry sponge for 5 minutes and exposing the bowel to the air for 30 minutes. Treated dogs received metoclopramide (0.4 mg/kg 4 times daily [QID] intravenously [IV]), whereas untreated dogs received a saline placebo, starting 1 hour after celiotomy closure. Recordings were made for 26 hours after induction of ileus. The phases of the migrating myoelectric complex (MMC) were identified and motility index values were determined. During ileus, the MMC phase II duration was increased at the duodenum and phase III duration was decreased at the antrum, pylorus, duodenum, and proximal segment of the jejunum (p less than 0.05). Motility index values were decreased at the antrum and duodenum during ileus (p less than 0.05). Treatment with metoclopramide reversed the MMC phase III inhibition at the antrum and pylorus, and partially reversed the inhibition at the duodenum and jejunum (p less than 0.05). Motility index values were restored to preoperative baseline values with metoclopramide treatment (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献
