1. AN AUTOMATIC DETECTION METHOD FOR ABNORMAL LAYING HEN ACTIVITIES USING A 3D DEPTH CAMERA
ABSTRACT With the increasing scale of farms and the correspondingly higher number of laying hens, it is increasingly difficult for farmers to monitor their animals in a traditional way. Early warning of abnormal animal activities is helpful for farmers’ fast response to the negative impact on animal health, animal welfare and daily management. This study i

2. Energy Potential of Animal Waste in the State of Paraná (Brazil)
Abstract Animal biomass is a source of energy commonly discarded without or with low utilization, but its availability draws attention to its reuse [1]. The utilization can be carried out in different ways, varying in terms of generation time and efficiency. The use of biodigestion requires a relatively small area compared to landfills or natural composting,

3. Diagnosis of Gallibacterium Anatis in Layers: First Report in Turkey
ABSTRACT Gallibacterium anatis, a member of the Pasteurellaceae family, leads to decrease in egg-production, animal welfare and increase in mortality. This study aimed to diagnose G. Anatis, which caused economic losses in laying hens by using conventional and molecular techniques. In this study, G. anatis was examined from a total of 200 dead chicken tissue

4. Diagnosis of Brachyspira pilosicoli, Brachyspira hyodysenteriae and Brachyspira intermedia in hens and laying hens in the western region of Paraná through bacterial isolation and identification in qPCR
RESUMO: Bactérias do gênero Brachyspira podem ocasionar enfermidades entéricas em aves acarretando a queda de produtividade. A ocorrência desta enfermidade em galinhas já foi verificada em países como a Austrália, Itália e Estados Unidos, porém no Brasil, até o momento, trabalhos epidemiológicos sobre a frequencia de Brachyspira sp. só foram real

9. Microbiological, Physicochemical, and Histological Analyses of Broiler Carcasses with Cachexia
ABSTRACT Broiler carcasses presenting cachexia, as determined by the federal inspection agency, were submitted to microbiological, physicochemical, and histological analyses. Over a 2-month period, 278 carcasses from straight-run flocks of 43- to 48-d-old Cobb broilers from two different farms were condemned due to cachexia and subjected to gross examination

11. Salmonella Enteritidis in Layer Farms of Different Sizes Located in Northern China: On-Farm Sampling and Detection by the PCR Method
ABSTRACT Salmonella enterica subspecies enterica serotype Enteritidis (SE) has caused foodborne infections over decades. It is transmitted mainly from contaminated eggs to humans. SE is commonly present in layer houses, and closely interacts with environmental factors. The objective of the present study was to develop a viable PCR method to identify SE in en
