Four sustainable deworming tips to battle parasite resistance
Beef Magazine online
2025-02-01
“We’ve been thinking about parasites in the short term for 30 to 40 years,” shared Christine Navarre, DVM, Extension veterinarian at Louisiana State University Agricultural Center. “Parasite resistance is a real concern. We must think about deworming in the short term and the long term; otherwise, we’ll be left with nothing to combat parasites.”

“Until you have a major stressor, usually nutritional stress, that allows parasites to cause severe health or mortality problems, it’s not noticed,” said Dr. Christine Navarre, DVM, MS, DACVIM and Extension veterinarian at the Louisiana State University AgCenter. “They are costing us money from subclinical problems long before we recognize them.”

Hurricane Laura unleashes swarms of livestock-killing mosquitoes

Fortunately, cattle owners have been able to thin their buggy numbers by crop-dusting their pastures with pesticide. Meanwhile, AgCenter extension veterinarian Dr. Christine Navarre said that ranchers can mitigate the mosquito swarms by applying steer-safe insecticides to their livestock.

Livestock fatalities attributed to a massive attack of dark rice field mosquitoes (Psorophora columbiae) following Hurricane Laura
The Bovine Practitioner2022
The objective of this case report is to characterize the sudden fatality of livestock associated with a massive attack of dark rice field mosquitoes (Psorophora columbiae) after the passage of Hurricane Laura in southwest Louisiana late August 2020. In 3 days, approximately 30 deer, 600 beef cattle, 100 sheep and 30 horses died following a brief history of weakness or, in most cases, no clinical signs prior to death. Several on-site visits were performed by veterinarians to evaluate animals and perform necropsies. Two deer were received for necropsy, and tissue samples from 1 bull and 1 horse were evaluated at the Louisiana Animal Diagnostic Disease Laboratory.
Epidemiology and Control of Gastrointestinal Nematodes of Cattle in Southern Climates
Veterinary Clinics of North America Food Animal Practice2020
Control of gastrointestinal nematodes (GIN) can have both economic and health benefits for cattle operations in the southern United States. In the past several decades, GIN control has relied almost exclusively on the use of anthelmintics. With the increase in anthelmintic resistance new strategies must be developed. Anthelmintic use should be minimized by integrating grazing management and a good herd health program into GIN control programs. This takes knowledge of GIN biology and epidemiology in the region (climate and weather) combined with specific information from the ranch.
Animal Contact in Public Settings-Risk Awareness of Enteric Pathogens and Hand Hygiene Behaviors
Food Control2018
Contact with animals in public settings can provide education and entertainment opportunities for both adults and children. However, outbreaks have been associated with human-animal interactions at state, region or county fairs, petting zoos, educational farms, etc. Those outbreaks not only raised a public health concern, but also had substantial medical, legal, and economic impacts. In this study, we assessed the risk awareness of enteric pathogens associated with animal contact in public settings. Participants were asked whether they recognize the risk of spreading enteric pathogens through specific animal contact behaviors such as petting animals with hands or eating around farm animals. The results showed that the self-reported risk awareness was 4.0 ± 1.2 out of a total score of 6, which indicated a poor risk awareness.
Preparation and Response for Flooding Events in Beef Cattle
Veterinary Clinics of North America: Food Animal Practice2018
Flooding appears to be occurring at an increased frequency and severity, resulting in significant losses to the beef cattle industry. Responding to the needs of beef cattle is a resource-intense occurrence and beyond that provided by most local jurisdictions. It is incumbent on livestock producers to develop continuity of operations or emergency plans designed to limit the financial losses and compromised animal welfare that occur when livestock are exposed to flood conditions. Livestock producers and the veterinary medical profession should also encourage and participate in the development of public emergency plans focused on limiting losses in this critical industry.
Coccidiosis in Large and Small Ruminants
Veterinary Clinics of North America: Food Animal Practice2018
Coccidiosis is an important parasitic disease of young ruminant livestock caused by the protozoan parasite of the genus Eimeria. Infection with Eimeria can lead to subclinical production losses and clinical disease. The most common clinical sign is diarrhea. Control of coccidiosis in cattle, sheep, and goats is based on sound management, the use of preventive medications, and treatment of clinical cases as necessary.
