Download or read book Gastrointestinal Nematodes of Sheep and Cattle written by Ian Scott and published by John Wiley & Sons. This book was released on 2009-11-02 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique resource for all those interested in the impact of worms on livestock, the anthelmintics used to get rid of them and the emerging problem of anthelmintic resistance. This book provides an over-arching view of past, present and suggested future strategies for control of gastrointestinal nematode parasites in sheep and cattle. The book begins with descriptions of the biology of gastrointestinal nematodes, the harm they cause to the host and their economic impact. The main body of the book deals with the control of worms, focusing on the use of anthelmintic drenches. The relationship between drenching practices and the development of drug resistance is discussed, as well as resistance management. The authors also break new ground by discussing alternative options for worm control, including: nutritional interventions, biological control, breeding for desirable genetics and artificially improving immunity to infection. They also offer useful recommendations for program development.

This book was released on 1977 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The epidemiology of nematode infections in ewes and lambs on irrigated pastures was investigated during one reproductive cycle in a commercial operation in Central Oregon. Primary objectives were to determine the sources of parasitism, the effect on lamb weight gains, and the effectiveness of control procedures in minimizing the detrimental effects of parasitism. Methodology included fecal nematode egg counts, animal necropsies and the use of tracer lambs. The relationships between blood trace mineral levels, parasitism and suboptimal weight gain in lambs and calves were also examined. High pasture burdens of infective larvae were found in spring and early summer from overwintering larvae and in late summer from autoinfestation by ewes and lambs. Lamb weight gain from March until mid-July was 0.48 lb/head/day. From mid-July until September when the study terminated, lamb weight gain declined ( -0.03 to 0.28 lb/head/day). Parasite burdens were low to moderate early in the grazing period, but increased markedly during the mid-July to September period, despite monthly deworming of the flock. It appeared that parasite burdens, high summer temperatures and the lack of shade, and possibly low cobalt and selenium levels were responsible for the late summer decline in weight gain. Evaluation of control measures indicated that intensive deworming prior to parturition eliminated arrested or inhibited larvae in the ewes. The periparturient relaxation of resistance, however, permitted development of infective larvae acquired from the pre- and post-lambing pastures. Maturation of these larvae caused a marked rise in post-parturient egg per gram counts of the ewes with subsequent relatively high rates of pasture contamination. Monthly deworming of the flock was moderately effective in reducing parasite burdens and pasture contamination. Alternate grazing of pastures by cattle and sheep, and ad lib. feeding of phenothiazine in salt were not effective as control measures.

Download or read book Parasites of Cattle and Sheep written by Andrew B. Forbes and published by CABI. This book was released on 2020-11-17 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding parasite biology and impact is essential when giving advice on parasite control in farm animals. In the first review devoted to parasites of domestic cattle and sheep alone, this book provides in-depth, focused advice which can be tailored to individual farms. It considers the impact of parasites, both as individual species and as co-infections, as well as epidemiological information, monitoring, and diagnostic procedures. Supported throughout by diagrams and photos to aid diagnosis, it also reviews the basis for control measures such as the responsible use of parasiticides, adaptive animal husbandry and other management practices.
