Kraków, Poland ♦Corresponding author: [email protected] Abstract The aim of the study was to determine the effect of caponizing on body weight and physicochemi- cal properties of meat of the capons – hybrids obtained from the crossing of hens of the Yellowleg Partridge (Ż-33) breed with meat roosters. The study covered 80 hybrid roosters, which were randomly assigned to two groups of 40 animals each (8 boxes of 10 birds in each group). Group I (control) consisted of uncastrated roosters while group II included birds, which were castrated at 8 weeks of age under local anaesthesia by a vet. Birds were fed ad libitum with the same standard diets and kept on litter under optimal environmental conditions with a stocking density of 7 ani- mals/m2. At the end of fattening, i.e. in the 20th week of life, 8 birds with a body weight close to the group average were selected from each group for slaughter. After slaughter, the effectiveness of the procedure was checked (lack of testicles), then the slaughter performance of birds, physicochemi- cal parameters of the pectoral and leg muscles were determined, and sensory evaluation was per- formed. The procedure of castration of hybrid roosters had a positive effect on body weight, feed conversion ratio and carcass traits. -

Ectoparasites of the Laughing Dove Streptopelia Senegalensis (Linnaeus, 1766) (Aves: Columbidae) in Zaria, Nigeria
Lundiana 9(1):67-71, 2008 © 2009 Instituto de Ciências Biológicas - UFMG ISSN 1676-6180 Ectoparasites of the Laughing Dove Streptopelia senegalensis (Linnaeus, 1766) (Aves: Columbidae) in Zaria, Nigeria 1Lucas K.

E-mail: [email protected] 2 Department of Biological Sciences, 3 Department of Surgery and Medicine, 4 Department of Veterinary Parasitology and Entomology, Ahmadu Bello University, Zaria, Nigeria. Abstract A survey of ectoparasites of the Laughing Dove (Streptopelia senegalensis Linnaeus, 1766) was carried out in Zaria, Nigeria, to determine the prevalence, intensity and mean intensity of infestation. A total of 382 (231 males and 151 females) doves trapped from different locations in Zaria, Nigeria, were examined through plumage brushing. Eighty-eight (23.0%) of the birds were infested by the following six species of ectoparasites: lice – 32 (8.4%) Menopon gallinae Linnaeus, 1758, 37 (9.7%) Columbicola columbae Linnaeus, 1758, and 18(4.7%) Goniodes sp.; flies – 19 (5.0%) Pseudolynchia canariensis Macquart, 1840; ticks – 12 (3.1%) Argas persicus Oken, 1818; and mite: 1 (0.23%) Dermanyssus gallinae (Degeer, 1778). The frequency of single infestations (59 – 15.4%), was higher than that of double (27 – 7.1%) and triple (2 – 0.52%) infestations, though the difference was not statistically significant (p > 0.05). The males had a higher prevalence (55 – 23.8%) than the females (33 – 21.9%). However, this difference was also not significant (p > 0.05). Ectoparasites were collected from the birds through out the year, with highest prevalence (60.0%) in November. -
Effect of Biosecurity and Management Practices on the Prevalence of Salmonella, Campylobacter, and Clostridium Perfringens in a Poultry Production System
Effect of biosecurity and management practices on the prevalence of Salmonella, Campylobacter, and Clostridium perfringens in a poultry production system by Katrina Grace English A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 12, 2015 Keywords: Biosecurity, management, poultry, survey, bacterial sampling Copyright 2015 by Katrina Grace English Approved by Kenneth S. Macklin, Chair, Extension Specialist and Professor, Department of Poultry Science, Auburn University Manpreet Singh, Associate Professor, Department of Food Sciences, Purdue University Joseph B. Hess, Extension Specialist Professor, Department of Poultry Science, Auburn University Abstract Salmonella, Clostridium perfringens, and Campylobacter are responsible for 30% of all foodborne illness cases and 50% of foodborne illness hospitalizations in the United States. Many of these cases and outbreaks have been linked to poultry products as the source of contamination. Because of the significant impact these pathogens have on human health, they are direct targets for pathogen reduction programs at various points during poultry production. Pre-harvest control points are the most recent targets for pathogen control due to increasing costs, regulations and the presence of diseases such as Avian Influenza (AI) and Necrotic Enteritis (NE) caused by C. perfringens. Of particular interest are the specific biosecurity and management practices that influence the transmission of pathogens in the poultry production environment. This study aimed to determine which practices influenced the transmission of Salmonella, C. perfringens, and Campylobacter on commercial poultry farms. In addition, this study collected data on the presence of two novel C. perfringens genes (netB and tpeL) that produce toxins and are associated with the disease NE in poultry. -

At the time, neither the animal rights movement nor the public at large knew very much about chickens or about how the poultry industry originated and developed in twentieth-century America to become the model for industrialized farmed-animal production around the world. Some informative articles and book chapters had appeared, but the poultry industry’s own detailed and glowing account of its transformation of the chicken, from an active outdoor bird scouring the woods and fields to a sedentary indoor meat and egg “machine,” filled with suffering, diseases, and antibiotics, remained largely unknown. The purpose of Prisoned Chickens, Poisoned Eggs was to bring this story to light in a way that would reveal the tragedy of chickens through the lens of the industry that created their tragedy without pity or guilt. The book became, as I’d hoped it would, a blueprint for people seeking a coherent picture of the U.S. -
