What is Sainfoin?

In the United States, especially the Southeast, sericea lespedeza (Lespedeza cuneata) is promoted as a tannin-containing forage that can reduce internal parasitism in small ruminants. In Europe, sainfoin (Onobrychis viciifolia Scop.) is reported to have the same effect. The consumption of sainfoin has been experimentally associated with a decrease in establishment of third stage infective larvae and a reduction in fecal egg count, due either to a reduced female fertility and/or (less frequently ) a reduced worm number. These "anthelmintic" effects depend on the concentration of condensed tannins in the diet ( a minimal threshold is necessary) and the length of distribution (at least 15 days

A Vaccine for Barber Pole Worm

Barbervax® was developed by the Moredun Research Institute, a UK-based animal health charity owned by farmers, with support from several Australian entities. It advertises itself as the first vaccine in the world for a gut dwelling parasite of livestock. Barbervax® is available in Australia, New Zealand, and South Africa. It is available via subscription in the UK. The Canadian and US sheep industries plan to work together in hopes of getting Barbervax® approved for sheep in Canada and the US. The US goat industry has a similar interest. Barbervax® controls barber pole worm (Haemonchus contortus) disease by reducing fecal egg counts and thus, build-up of infections. It requires three "primin

Fight the Fluke

Liver flukes can be found anywhere in areas with high rainfall and standing water. The ideal regions of the US are the Southeast and Northwest. The life cycle depends on an aquatic environment as that is where the snails (intermediate host) are active. There are many snail species, but only one species can act as the intermediate host, therefore limiting potential transmission. The snails come out of aestivation (dormancy) when the temperature and rainfall increase in the spring and go back into aestivation during early summer especially when conditions are hot and drier. Asexual reproduction in the snail results in a great many infective forms being available attached to forage that is now

Mini-FLOTAC Devices Now Available

The lab of Dr. Rap Kaplan at the University of Georgia is now the North America distributor of the Mini FLOTAC fecal egg counting devises. These devises have a higher sensitivity for detecting eggs in fecal samples. The increased sensitivity (5 EPG) of the Mini FLOTAC is helpful for livestock species with lower fecal egg counts and/or where the fecal egg count reduction test (FECRT) is being used to check for efficacy against dewormers. The Mini FLOTAC is recommended for research and fecal egg count reduction tests while other fecal egg counting methods are still appropriate for use by clinical veterinarians for routine fecal testing.

Registration Now Open

Registration for the 2019 Delmarva Small Ruminant Conference All Worms All Day is now open. The registration link is https://www.ext.vsu.edu/events/2019/12/7/all-worms-all-day-delmarva-small-ruminant-conference. The conference will be held Saturday, December 7 at Lincoln Memorial University in Ewing, Virginia. It is the third All Worms All Day Conference. The first conference was held in 2017 at Delaware State University. Last year's conference was hosted by the University of Maryland. All topics will pertain to internal parasite control (worms + coccidia). All speakers are members of the American Consortium for Small Ruminant Parasite Control. There will be a separate program for older yout
