Producer Opinions On Antibiotic Use In The Beef Industry, T. Lee, C. D. Reinhardt, E. F. Schwandt, D. U. Thomson

Kansas Agricultural Experiment Station Research Reports

Antibiotic use in the beef industry is of increasing interest to consumers and has become a point of discussion for producers, veterinarians, and professional scientists in recent years. With the vast amount of information available on the internet and social media, consumers are becoming more knowledgeable about beef production practices and the use of antibiotics in the food animal industries. Furthermore, scientists have devoted a large amount of time and money to research to investigate consumer opinions and perspectives about management practices used in food animal production. However, many of these investigations fail to include the opinions and perspectives of …

Determining The Impact Of By-O-Reg+ In Diets With Or Without A Feed Grade Antibiotic On Growth Performance Of Nursery Pigs, L. L. Thomas, J. C. Woodworth, R. D. Goodband, J. M. Derouchey, M. D. Tokach, S. S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 717 nursery pigs (PIC C-29 × 28 and PIC L3-1050 × 1040, initially 12.48 ± 0.10 lb) from two consecutive nursery groups were used in a 35-d growth study. The objective was to determine the impact of increasing levels of By-O-Reg+ in diets with or without 50 g/ton Carbadox. By-O-Reg+ is a unique mixture of essential oils primarily based on oregano. It utilizes encapsulation technology to stabilize the essential oils and is suggested to have antimicrobial-like properties. The present study evaluated growth performance of nursery pigs fed 1 of 6 dietary treatments that were arranged as a …

Detection Of Sensitive And Mutant Ruminal Bacteria Isolates From Sheep, Cattle, And Buffalo Using 14 Therapeutic Antibiotics, Abdelfattah Zeidan Mohamed Salem, Roberto Montes De Oca Jimenez, Maria Andrea Cerrillo-Soto, Ahmed Eid Kholif, Mohamed Zidan Mohamed Salem, Mona Mohamed Mohamed Yasseen Elghandour

Turkish Journal of Veterinary & Animal Sciences

In the present study, sensitive and mutant colonies of some ruminal bacterial species isolated from sheep, cattle, and buffalo were detected. We counted and considered \"mutant colonies\" the bacterial colonies grown in the clear inhibition zone in the Kirby-Bauer disk diffusion susceptibility test. Detected mutant colonies were higher in buffalo than in cattle and sheep. Duricef and metronidazole caused no mutations in any species. The others formed mutant colonies, where roxithromycin = polymyxin = chloramphenicol = gentamicin < erythromycin < vancomycin < piperacillin = cefotaxime < streptomycin < cefoperazone < ciprofloxacin < amikacin. Sheep had the highest number of sensitive isolates, and the number of sensitive isolates was dramatically lower in cattle and buffalo. There were no sensitive isolates with the antibiotic metronidazole, and there was a low number of sensitive isolates with duricef. The other antibiotics had more sensitive isolates (gentamicin = ciprofloxacin = amikacin > streptomycin = piperacillin > erythromycin > vancomycin = cefoperazone = cefotaxime > roxithromycin > polymyxin > chloramphenicol). The number of sensitive isolates of the different ruminant species for …

Marker Dyes In Antibiotics, K Needham, N. Ingleton

Journal of the Department of Agriculture, Western Australia, Series 4

'For some years the presence of penicillin in milk has been a serious problem for the dairy industry.

When cows are treated for mastitis with antibiotics some residue finds its way into the milk.

Unless the milk from treated cows is withheld for at least 72 hours after treatment this residue enters the bulk milk supply.

Antibiotics And Sterilisers In The Dairy Industry, K Needham, N. Ingleton

Journal of the Department of Agriculture, Western Australia, Series 4

A S a consequence of the rapid advances made in all aspects of technology there are an ever increasing number of preparations becoming available to the dairy farmer, to assist both in the control of disease in his crops, pastures and animals and to maintain and enhance the quality of his dairy products.

These are—antibiotics, sterilisers, detergents, various weedicides and pesticides
