UCD School of Agriculture Food Science and Veterinary Medicine, Belfield, Dublin 4, D04, V1W8, Ireland; UCD Institute of Food and Health, Belfield, Dublin 4, D04, V1W8, Ireland; UCD Centre for Food Safety, University College Dublin, Belfield, Dublin 4, D04, V1W8, Ireland.

Chickens play host to a diverse community of microorganisms which constitute the microflora of the live bird. Factors such as diet, genetics and immune system activity affect this complex population within the bird, while external influences including weather and exposure to other animals alter the development of the microbiome. Bacteria from these settings including Campylobacter and Salmonella play an important role in the quality and safety of end-products from these birds. Read More

Food Chem Toxicol 2021 Jun 10;154:112334. Epub 2021 Jun 10.

Department of Veterinary Medicine and Animal Production, University of Naples, Via F. Delpino, 1, 80137, Napoli, Italy. Electronic address:

The occurrence of analogues of bisphenol A (BPA), including bisphenol F(BPF) in milk is still not well known. BPF may enter the milk chain at the farm and during milk processing at the dairy company. This study identified the main BPF contamination pathways using a monitoring model based on the identification of the hazard at three stages along the dairy chain: raw milk from the storage tank, pasteurized milk from the storage tank, and cardboard packaged milk.

A study on the use of thermal imaging as a diagnostic tool for the detection of digital dermatitis in dairy cattle.

J Dairy Sci 2021 Jun 4. Epub 2021 Jun 4.

Department of Livestock and One Health, Institute of Infection, Veterinary and Ecological Sciences, University of Liverpool, Leahurst Campus, Chester High Road, CH64 7TE, United Kingdom. Electronic address:

Our aims were to (1) determine how interdigital skin temperature (IST), measured using infrared thermography, was associated with different stages of digital dermatitis (DD) lesions and (2) develop and validate models that can use IST measurements to identify cows with an active DD lesion. Between March 2019 and March 2020, infrared thermographic images of hind feet were taken from 2,334 Holstein cows across 4 farms. We recorded the maximum temperature reading from infrared thermographic images of the interdigital skin between the heel bulbs on the hind feet. Read More

Environmental impacts of animal-based food supply chains with market characteristics.

Sci Total Environ 2021 Aug 14;783:147077. Epub 2021 Apr 14.

School of Biosystems & Food Engineering, University College Dublin, Belfield, Dublin 4, Ireland.

Animal-based food supply chains lead to significant environmental impacts, which can be influenced by production systems, distribution networks and consumption patterns. To develop strategy aimed at reducing the environmental impact of animal-based food supply chains, the common environmental hotspots among different types of food, the role of transport logistics and the consequence of end market need to be better understood. Life cycle assessment was adopted to model three types of animal-based food chains (beef, butter and salmon), with specific technologies, high spatial-resolution logistics and typical consumption patterns for three markets: local, regional (intra-European) and international.

Arch Anim Breed 2021 29;64(1):35-44. Epub 2021 Jan 29.

College of Animal Science, Jilin University, Changchun, Jilin 130062, PR China.

Mitochondrial glycerol-3-phosphate acyltransferase () catalyses the initial and rate-regulated first-stage pathway of glycerol lipid synthesis and helps to allocate acyl-CoA (acyl-coenzyme A) to triglyceride (TG) synthesis and away from degradation pathways in animal lipometabolism-related pathways. In this study, RNA interference (RNAi) and gene overexpression were used to examine the correlation between the expression of and adipogenesis in bovine mammary epithelial cells (bMECs). Additionally, three novel polymorphisms were identified within the bovine key functional domain of with Sanger sequencing. Read More

Department of Animal Biosciences, Animal Science and Nutrition, University of Guelph, Guelph, ON, Canada N1G 1Y2. Electronic address:

Dairy calf nutrition is traditionally one of the most overlooked aspects of dairy management, despite its large effect on the efficiency and profitability of dairy operations. Unfortunately, among all animals on the dairy farm, calves suffer from the highest rates of morbidity and mortality. These challenges have catalyzed calf nutrition research over the past decade to mitigate high incidences of disease and death, and improve animal health, growth, welfare, and industry sustainability.

Gastrointestinal parasites in Swedish pigs: Prevalence and associated risk factors for infection in herds where animal welfare standards are improved.

Vet Parasitol 2021 Jul 18;295:109459. Epub 2021 May 18.

Department of Animal Health and Antimicrobial Strategies, National Veterinary Institute, SVA, 751 89, Uppsala, Sweden; Swedish University of Agricultural Sciences, Department of Clinical Sciences, Box 7054, 750 07, Uppsala, Sweden.

The global pig production has undergone major changes over the past 30 years with larger farms, more intensified production as well as improved hygiene and biosecurity practices. To investigate whether these changes, along with expanded pig welfare, have had an impact on parasite occurrence, a cross-sectional study was conducted in Sweden on farms where the pigs are always loose-housed, floors are solid and bedding material is provided. A total of 1615 faecal samples were collected on 42 conventional indoor farms from a) post-weaning piglets (n = 337); b) growers (n = 345); c) fatteners (n = 308); d) dry sows (n = 277) and e) pre-partum sows (n = 348).

Front Physiol 2021 29;12:678054. Epub 2021 Apr 29.

Institute of Farm Animal Genetics, Friedrich-Loeffler-Institut, Neustadt, Germany.

The high laying performance of today's laying hens places enormous demands on their mineral metabolism. While up-to-date data are rare, the present study aimed to describe blood parameters associated with egg laying and bone metabolism during the pre-laying period, in the course of the laying period and the daily egg laying cycle. Ten to 15 laying hens of two high-performing, phylogenetically divergent lines (BLA: brown-egg layer; WLA: white-egg layer), kept in single cages were blood sampled at 17, 25, 29, 49, and 69 weeks of age.

Appl Environ Microbiol 2021 May 14. Epub 2021 May 14.

Food, Nutrition and Health Program, Faculty of Land and Food Systems, The University of British Columbia, Vancouver, BC, V6T 1Z4, Canada

Horizontal gene transfer (HGT) is a driving force for the dissemination of antimicrobial resistance (AMR) genes among , a leading cause of foodborne gastroenteritis worldwide Although HGT is well documented for planktonic cells, the role of biofilms in AMR spread that likely to occur in the environment is poorly understood. Here, we developed a co-cultivation model to investigate the HGT of chromosomally-encoded AMR genes between two F38011 AMR mutants in biofilms. Compared to planktonic cells, biofilms significantly promoted HGT ( < 0. Read More

Trends in bird abundance differ among protected forests but not bird guilds.

Ecol Appl 2021 May 14:e02377. Epub 2021 May 14.

Department of Forestry, Michigan State University, East Lansing, Michigan, 48824, USA.

Improved monitoring and associated inferential tools to efficiently identify declining bird populations, particularly of rare or sparsely distributed species, is key to informed conservation and management across large spatiotemporal regions. We assess abundance trends for 106 bird species in a network of eight forested national parks located within the northeast United States from 2006 to 2019 using a novel hierarchical model. We develop a multispecies, multiregion, removal-sampling model that shares information across species and parks to enable inference on rare species and sparsely sampled parks and to evaluate the effects of local forest structure.
