A procedure involving alkaline extraction and solution 31P nuclear magnetic resonance (NMR) spectroscopy was developed and optimized for the characterization of P in animal manures (broiler, swine, beef cattle). Inclusion of ethylenediaminetetraacetic acid (EDTA) in the alkaline extraction solution recovered between 82 and 97% of the total P from the three manures, which represented a significa...

A prospective cohort study was performed to evaluate the prevalences and loads of Salmonella and Campylobacter spp. in farm and processing plant samples collected from 55 commercial broiler chicken flocks. Environmental samples were collected from broiler houses within 48 h before slaughter, and carcass rinses were performed on birds from the same flocks at 4 different stages of processing. Sal...

The epidemiological, clinical and clinical pathological findings in 20 cattle and 4 sheep from 15 outbreaks of poultry litter toxicity in South Africa over the past 6 years are documented. In 6 outbreaks, the litter emanated from batteries where maduramicin had been incorporated into rations of broilers. According to circumstantial evidence the litter involved in the 9 other outbreaks was also ...

An experiment was carried out with SHAVER Starbro broiler parent stock from one day old to the point of peak production to investigate the growth, early laying performance and their adaptability during brooding, growing and early laying periods. The experimental period was divided into five phases, phase I (0 – 2 week), phase II (3 – 8 week), phase III (9 – 22 week), phase IV (23 – sexual matur...

Several elements of the agricultural nonpoint source control program in the Chowan River basin are reviewed to give direction to future efforts. In-stream water quality monitoring, interviews with farmers, and analysis of agricultural production trends have revealed several major points which need consideration in implementation efforts. Due to difficulties in documenting water quality improvem...

Introduction The air of animal houses contains bioaerosols like viruses bacteria, fungi, endotoxins and allergens that present a health risk for humans and animals [1]. Airborne pathogen bacteria, fungi that cause allergies and endotoxins were detected in poultry houses [2]. The spreading of bioaerosol emissions from poultry houses is less understood and therefore it is difficult to estimate th...

The objectives of the two studies presented were to estimate the prevalence of Campylobacter-positive farms and flocks and to acquire updated knowledge about risk factors for the introduction of Campylobacter in Danish broiler flocks. In the first study, from September 2010 to September 2011, there were 25 Danish broiler farms visited, and a questionnaire was filled in by a veterinarian/consult...
