Watch Out for Scrapie

Published

on

By Barry Whitworth, DVM

Scrapie is a chronic, progressive disease of the central nervous system that affects sheep and goats. Scrapie is the oldest of the group of neurodegenerative diseases known as transmissible spongiform encephalopathies (TSE).

Some of the other TSE are Bovine Spongiform Encephalopathy known as mad cow disease, Chronic Wasting Disease which is found in deer, and Creutzfeldt Jacob Disease which is found in humans. TSE are protein-misfolding diseases that lead to brain damage and are always fatal.

The cause of Scrapie is not completely understood, but evidence indicates that an infectious protein referred to as a prion is responsible for the disease.
These infectious prions cause damage to the normal prion proteins found in the brain. The mis-folding of the proteins lead to brain damage and the presentation of clinical signs of the disease. Prions are very resistant to destruction, so once in the environment, they are difficult to remove.

At the writing of this article, High Path Avian Influenza (HPAI) H5N1 has been detected in more than 83 million domestic poultry in the United States. The outbreak includes commercial and backyard flocks.

Most people are aware that poultry may succumb to Avian Influenza but may not know that other animals can be infected with the virus. According to the U.S. Department of Agriculture, a variety of mammals have been infected with Avian Influenza H5N1 in the U.S.

The list of more than 200 mammals includes bears, foxes, skunks, coyotes, etc. Even marine animals such as dolphins and seals have been found with the virus. Current Avian Influenza H5N1 infections in poultry, mammals, and livestock in the U.S. can be found at the Detections of Highly Pathogenic Avian Influenza website at https://www.aphis.usda.gov/livestock-poultry-disease/avian/avian-influenza/hpai-detections.

Recently, ruminants have been diagnosed with Avian Influenza H5N1 in the U.S. The World Organization for Animal Health reported that neonatal goats displaying neurological clinical signs and death were positive for Avian Influenza.

Meanwhile, Back at the Ranch…

When May arrives, we start thinking about weed control. With two years of drought under our belts, grass grazed short and hay stocks depleted, what we do now will influence our forage conditions for the entire year. With 75 percent of our annual warm season forages made by July 15 in North Texas, we need to get the grass growing while the sun shines.

Speaking of the sun shining, the biggest deterrent to growing lots of grass is restricted sunlight, and the biggest sun blockers we have are weeds.

Have you noticed weeds are normally just slightly taller than your grass and are probably blocking 90 percent of the sunlight from reaching the grass itself? So obviously, we need to improve conditions, so sunlight reaches the plants we want to grow.

With grass extremely short, more sunlight is hitting the soil surface now, which in turn results in more weed seed germinating. With the moisture we have received, we expect an abundance of weeds this year.

Land Market Report: March Land Sales

Published

By

By Jared Groce

Rural land sales are continuing on a steady pace for early spring, with prices holding very strong with the sell-to-list price ratios remaining very high, even on properties that have been on the market for a longer than usual time period. The total number of transactions are picking up once again as the spring selling season kicks off, and the average acreage continues to decrease.

Larger acreage properties seem to be in higher demand than smaller properties currently, with many buyers simply parking cash in real estate to hedge against inflation. Interest rates seem to have settled down and most experts agree that rates will be reduced by the fed this year. Some lenders have programs in place that allow the buyer to reduce their rates without having to go through a full refinance ordeal.
