Avian influenza: Expert talks about spread, risks and response in cows and poultry

4 weeks ago | poultryworld.net | Zana van Dijk

Poultry World and sister publication Dairy Global asked Prof Dr Timm Harder, head of WOAH, FAO, and National Reference Laboratory for Avian Influenza at the Friedrich-Loeffler-Institut to shed some light on the spread of avian influenza in the US. In this Q&A he discusses transmission in dairy cows and poultry, control measures and preventative strategies. We have seen the transfer of highly pathogenic avian influenza from cattle and poultry to humans (in the US).
Which US states will see avian influenza emerge and which are at greater risk?

To answer some important questions surrounding H5N1, scientists looked at the ongoing H5N1 influenza in dairy cows in the US in a recent study. Which states will be impacted in the future and are at higher risk? Is under-reporting of avian influenza in dairy cows an important factor, and what about the sufficiency of current interventions? In this research the scientists also present a simulation model to test transmission and predict the scale of the disease.
Heat stress and its impact on fertility traits in dairy cows

What impact does heat stress have on conception rate, interval calving to first insemination, interval first to last insemination and calving interval in dairy cows? Researchers reveal their findings in a recent study. In this study, published in the Journal of Dairy Science, researchers used temperature-humidity index as an indicator for assessing heat stress conditions for fertility traits in the Holstein dairy cattle breed in the Netherlands.
Bird flu: Expert talks about spread, risks and response in cows and poultry

Dairy Global asked Prof Dr Timm Harder, head of WOAH, FAO, and National Reference Laboratory for Avian Influenza at the Friedrich-Loeffler-Institut to shed some light on the spread of avian influenza in the US. In this Q&A he discusses transmission in dairy cows and poultry, control measures and preventative strategies. We have seen the transfer of highly pathogenic avian influenza from cattle and poultry to humans (in the US). Can you explain reasons behind the increase in this?
Reliably detecting FMD and the role of small ruminants in transmission

2 months ago | dairyglobal.net | Zana van Dijk

A study carried out by researchers recently at the Pirbright Institute in collaboration with the National Veterinary Institute took place in northern Nigeria to evaluate reliable methods of detecting FMD virus in endemic settings. It also looked at the role of small ruminants in transmission of the virus. Standard testing of Foot and Mouth Disease virus (FMDv) methods are particularly challenging in endemic countries with scarce resources and where multiple FMDv serotypes circulate.
Onion peel feed additive cuts methane in dairy cows

2 months ago | allaboutfeed.net | Zana van Dijk

Showing promise as a natural feed additive, a recent study evaluated the impact of onion peel in dairy cow diets. Results indicate better nutrient degradability and the potential to reduce methane. The study, published in the journal Animals, reveals that onion peel, a by-product of the onion processing industry, is showing promise as a natural feed additive and the potential to reduce methane emissions.

FMD Europe: Austria closes borders for pigs, cattle

2 months ago | pigprogress.net | Zana van Dijk

Austria has closed 24 small border crossings with Hungary and Slovakia in an attempt to stop the spread of Foot-and-Mouth Disease (FMD) into the country. Austria was last affected by FMD in 1981. The Austrian border closures as of 5 April were announced in the wake of the emergence of the disease in cattle in recent weeks (March) in both Hungary and Slovakia, both countries have been free from FMD for 50 years.
Financial support to combat avian influenza in livestock in the US

Researchers at the University of Minnesota recently received a grant of US$1.5 million towards projects that will be seek to understand bird flu transmission and to mitigate the impact of the disease in dairy herds and the livestock sector as a whole. The University’s College of Veterinary Medicine stated it received the funding in a cooperative agreement grant from the US Department of Agriculture (USDA).
Dealing with FMD cost-effectively: preparation helps

2 months ago | dairyglobal.net | Zana van Dijk

A recent study looked at different livestock settings in Italy to assess the spread of Foot-and-Mouth Disease (FMD) in relation to the cost effectiveness of potential control strategies. The study highlights that thestructure and density of FMD-susceptible species populations play an important role in disease spread and the choice of a control strategy. Transmission is, therefore, strongly related to distribution and density of FMD-susceptible animals.
