This book was released on 1976 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of the northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), on body weight, reproductive potential and hematology of White Leghorn roosters were studied. Mean body weight was approximately 100 g. less for the mite infested roosters than for the uninfested roosters 4 weeks after they were infested with the northern fowl mite. Both groups increased in weight throughout the 26 weeks of the test but the differences in weight remained. Reproductive potential studies showed that after moderate populations of mites (101-1,000 mites/rooster) were observed, the volume of seminal fluid decreased. Four weeks before the test ended, one half of the infested roosters produced an average of less than 0.1 ml. of seminal fluid per week while the other half showed a decrease of 0.07 ml. in volume of seminal fluid produced when compared with the controls. Sperm concentration of mite infested roosters increased as the volume of seminal fluid decreased but was not statistically different from the controls. Motility and live/dead ratios of sperm did not show significant differences. Serum testosterone levels were statistically different between mite infested and control roosters. Hematology studies showed the greatest decrease in RBC and PCV occurred from the 4th to the 8th weeks when infestations were initially increasing rapidly. Mean Hemoglobin concentrations for the infested birds were consistently lower but not statistically different from the controls. No specific anemia could be attributed to mite populations as all hematological values were within normal ranges.

Available in PDF, EPUB and Kindle. Book excerpt: Parasiticide Discovery: In Vitro and In Vivo Tests with Relevant Parasite Rearing and Host Infection/Infestation Methods, Volume One presents valuable screening methods that have led to the discovery of the majority of parasiticides commercialized in the animal health industry. As much of the knowledge of parasiticide discovery methods is being lost in the animal health industry as seasoned parasitologists retire, this book serves to preserve valuable methods that have led to the discovery of the majority of parasiticides commercialized in animal health, also giving insights into the in vitro and in vivo methods used to identify the parasiticide activity of compounds. Addresses current issues of resistance, along with combination uses for resistant parasites Presents useful, authoritative information (chemical, pharmaceutical, clinical, etc.) for the pyrantel family of compounds Includes a discussion on screening methods in combination therapies Provides cutting-edge material for an evolving area of scientific discussion Includes in vitro and in vivo screens and parasite maintenance and culture methods
