The Coronavirus Disease 2019 (COVID-19) is the first known pandemic caused by a coronavirus. Its causative agent, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), appears to be capable of infecting different mammalian species. Recent detections of this virus in pet, zoo, wild, and farm animals have compelled inquiry regarding the zoonotic (animal-to-human) and reverse zoonotic (human-to-animal) transmissibility of SARS-CoV-2 with the potential of COVID-19 pandemic evolving into a panzootic.

Bovine Leukemia Virus (BLV) is an oncogenic virus which is the etiological agent of a neoplastic disease in infected cattle called enzootic bovine leukemia (EBL). The most common and sensitive diagnostic methods for EBL like enzyme-linked immunosorbent assay (ELISA) is time-consuming and requires manual handling which makes it unsuitable as an on-farm diagnostic test. Hence, there is a need for an alternative test with rapid detection and reduced manual labour. Read More

The pattern of duck sternal ossification and the changes of histological structure and gene expression therein.

Poult Sci 2021 Mar 12;100(7):101112. Epub 2021 Mar 12.

Farm Animal Genetic Resources Exploration and Innovation Key Laboratory of Sichuan Province, College of Animal Science and Technology, Sichuan Agricultural University, Chengdu, Sichuan 611130, China.

As the largest single bone, avian sterna are very different from those of mammals in terms of morphology and functions. Moreover, years of artificial selection in poultry led to incomplete sternal ossification at slaughter age, which may cause diseases, sternal injury, and restriction to breast muscle growth. However, in living birds, studies have rarely described the ossification pattern and underlying mechanisms of the sterna. Read More

Simultaneous adoption of diversification and agricultural credit to manage catastrophic risk for maize production in Bangladesh.

Environ Sci Pollut Res Int 2021 Jun 11. Epub 2021 Jun 11.

College of Economics and Management, Huazhong Agricultural University, Wuhan, 430070, People's Republic of China.

Risk management strategies are made up of response variability that may lessen the likeliness of an unfavorable event occurring and/or decrease the damaging consequences if that event happens. To minimize the risk, farmers respond in three ways which are considered to be risk managing tools; these are production, marketing, and financial responses. This study aimed to look at the potential associations and effects of implementing multiple risk management techniques at the same time, as very limited number of research is available in this field.

Multispecific resistance of sheep trichostrongylids in Austria.

Parasite 2021 11;28:50. Epub 2021 Jun 11.

Institute of Parasitology, Department of Pathobiology, Vetmeduni Vienna, Veterinärplatz 1, 1210 Vienna, Austria.

Anthelmintic overuse and failure to implement methods preventing the development and spread of anthelmintic resistance (AR) have led to an alarming increase of resistant ovine trichostrongylids worldwide. The aim of the present study was to determine whether the routine anthelmintic treatment strategy was effective, to obtain insights into the frequency of AR in trichostrongylids of sheep in Austria, and to determine the presence of different trichostrongylid genera. On 30 sheep farms, the faecal egg count reduction test (FECRT) was performed with the Mini-FLOTAC technique in two consecutive studies. Read More

4D printing: Perspectives for the production of sustainable plastics for agriculture.

Biotechnol Adv 2021 Jun 7:107785. Epub 2021 Jun 7.

Farm Structures Lab., Department of Natural Resources and Agricultural Engineering, Agricultural University of Athens, Greece.

The concept of 4D printing of phase change materials is gaining attention in the potential development of self-healing materials for tissue engineering and manufacturing applications, but there has been limited utilization of the technology in agriculture/farm-based applications. The temperature-responsiveness, magneto-responsiveness, pH-responsiveness, and osmotic pressure-responsiveness of shape-memory materials have potential applications in green/compostable plastics for agricultural applications such as food packaging and mulching films, shade nets, and greenhouse polymer covers. The application of 4D printing in augmenting the biodegradability, environmental, economic, and production benefits of polymers in agriculture is the main focus of this review. Read More
