Artificial Insemination of Gilts with 1.5 Billion Sperms Stored in Different Periods Associated with Different Pre-ovulatory Intervals     

PE Bennemann  GN Diehl  E Milbradt  RM Vidor  HCC Fries  I Wentz  ML Bernardi  FP Bortolozzo 《Reproduction in domestic animals》2005,40(6):507-510

This study evaluated the reproductive performance of gilts inseminated at three intervals before ovulation (0-12, 13-23, 24-30 h) with sperm doses (SD) stored for 0-48 and 96-120 h. A total of 218 PIC Camborough 22 gilts were inseminated once with SD of 1.5 x 10(9) sperms. Pregnant gilts (n = 166) were slaughtered 30.8 +/- 3.7 days after artificial insemination. The number of corpora lutea (CL) and total embryos (TE) was counted. Pregnancy rates (PR) were analysed by chi-square test. TE and embryonic survival (ES), obtained as the ratio between viable embryos and CL, were analysed by GLM procedure (SAS) and mean values were compared by Tukey's test. Pregnancy rate was similar among artificial insemination-ovulation (AIOV) intervals when semen was stored for 0-48 h. However, the lowest PR was observed in the 24-30 h AIOV interval with storage time (ST) of 96-120 h (p < 0.05). There was a significant effect of the interaction between ST and AIOV (p < 0.05) on TE and ES variables. Total embryos and ES did not differ (p > 0.05) among AIOV intervals in ST of 0-48 h. However, gilts inseminated at 24-30 h AIOV interval with ST of 96-120 h showed a reduction of 6.7 embryos (p < 0.05) compared with gilts in the same interval inseminated with semen stored for 0-48 h. ES for the 24-30 h AIOV interval and ST of 96-120 h was lower than that observed in the other groups (p < 0.05).  相似文献

Use of bacteriological techniques in the quality control of poultry slaughtering     

R Fries 《Berliner und Münchener tier?rztliche Wochenschrift》1990,103(9):306-311

Factors influencing the bacteriological status of materials, treated on a special stage of processing, can be detected by analysis of the flow of production. Changing the design of equipment, change of the production flow and education of the personnel who is handling the equipment can eliminate or minimize the risks. The data are to be collected on the basis of the special conditions of the plant. The daily checks can be performed by visual inspection or by using physical techniques.  相似文献   

Quantification of water as a potential risk factor for cross-contamination with Salmonella,Campylobacter and Listeria in a poultry abattoir     

A. Hamidi  H. Irsigler  D. Jaeger  A. Muschaller  R. Fries 《British poultry science》2014,55(5):585-591

1. Water used in a modern poultry processing line was tested from October 2005 to June 2006 to determine the level of bacteria in an abattoir in Germany.

2. A total of 420 water samples were taken from 14 processing sites (PSs), at 10 times, and from three different hours of the working shift at three sampling hours (SHs) at 5:00 a.m. (SH 1), 9:00 a.m. (SH 2) and 12:00 a.m. (SH 3). Each sample was assessed for the aerobic plate count (APC) and the prevalence of Salmonella, Campylobacter, Listeria and Yersinia over 30 sampling weeks. The APC numbers of each PS from three SHs were compared, and the prevalence of Salmonella, Campylobacter, Listeria and Yersinia from each PS of three SHs was determined as well as change from the initial PS to the end of the processing line.

3. A total of 46 water samples were positive for Salmonella, 120 positive for Campylobacter and 4 positive for Listeria. None of the water samples was found to be positive for Yersinia. During the course of the day, the APC increased. Salmonella was mostly found during SH 1 (5 a.m.) in water from all PSs. A high number of Campylobacter were observed at SH 2 (9 a.m.) and SH 3 (12 a.m.) from all PSs.

4. The results show that water, which is still used in substantial amounts in present poultry processing technology, can serve as a carrier for Salmonella and Campylobacter.

5. The findings indicate that birds might progressively contaminate the equipment and become contaminated via the same equipment, that water at every processing position of the line constitutes a risk and that more attention should be paid to effective water management in the processing plan.  相似文献

The shell-forming glands of Japanese quail fed p,p'-DDT or p,p'-DDE had carbonic anhydrase activity 16 to 19 percent lower than shell glands of quail on a diet free of pesticides.  相似文献   

Treatment of canine hip dysplasia: a review.          下载免费PDF全文

A M Remedios  C L Fries 《The Canadian veterinary journal. La revue veterinaire canadienne》1995,36(8):503-509

This article discusses the treatment approaches and recommendations for canine hip dysplasia. A search of the literature database MEDLINE (1969-1994) was conducted and relevant journal articles regarding the medical and surgical treatment of hip dysplasia were selected and reviewed. Dysplastic dogs can be divided, for treatment purposes, into those with no or minimal osteoarthrosis, and those with moderate to severe osteoarthrosis. In young animals with joint laxity and pain, but with no or minimal radiographic evidence of osteoarthrosis, the treatment approach is controversial. Conservative management may be effective in the short term, but progressive development of osteoarthrosis occurs and clinical signs may manifest at an older age. Options for surgical treatments in these young dogs include pectineal myectomy, lengthening of the femoral neck, and corrective osteotomies. Corrective osteotomies are advocated to reestablish joint congruency and prevent development of osteoarthrosis. In the mature osteoarthritic dog, effective conservative management depends on the severity of the degenerative joint disease. Proposed surgical treatments for clinically debilitating hip dysplasia include biocompatible osteoconductive/shelf arthroplasty; femoral head and neck excision arthroplasty, with or without muscle sling interposition; and total hip replacement. Although research directly comparing the salvage procedures has not been reported, studies suggest that total hip replacement is more effective in returning large dogs to full functional weight bearing.  相似文献

Microflora of two different types of poultry litter   总被引：1，自引：1，他引：0  

Fries R  Akcan M  Bandick N  Kobe A 《British poultry science》2005,46(6):668-672

1. The microbiological composition of litter (straw and wood shavings) was sampled, prior to placing 1-d-old chicks, during housing of the birds and after depopulation. Two independent trials were conducted. 2. The total aerobic plate count (APC) was determined and the predominant microflora of the samples was identified using flow charts. 3. Before chick placement, the APC of wood shavings (about 4.0 log/g) was lower than the APC of straw (about log 7.5/g). With stocking, in both types of litter the APC increased to about log 9.76/g straw-litter and log 9.89/g wood shavings, respectively. After depopulation, the APC remained high (> log 9 in both types of litter) within the period of observation. 4. From both experiments, 1981 isolates were collected and identified, most of them were Gram-positive. During stocking the birds, the number of Gram-positive isolates (in particular Gram-positive irregular rods and Micrococcaceae) increased; after depopulation it stayed at that high value, whereas the number of Gram-negative isolates remained low. In both types of litter the isolates were obtained in a comparable proportion.  相似文献   

Ventral rhinotomy in the dog and cat   总被引：3，自引：0，他引：3  

D L Holmberg  C Fries  J Cockshutt  D Van Pelt 《Veterinary surgery : VS》1989,18(6):446-449

The nasal cavities of 14 dogs and three cats were explored surgically using a ventral rhinotomy. The exposure achieved through this approach was considered to be equal to a dorsal rhinotomy. One animal died during the immediate postoperative period from perforation of a gastric ulcer. The other animals recovered well and had no significant complications. The long-term survival of the animals was consistent with previous reports for their diseases. Ventral rhinotomy is no more difficult than dorsal rhinotomy, has less patient morbidity and fewer postoperative complications, and is more cosmetically acceptable.  相似文献
