General Meeting 20 April 2019 at 11:30AM

Hi All,

Well spring is in the air and that means it’s time to plan our GSSB Spring General Meeting. This year’s Spring General Meeting will take place on 20 Apr 19 @ 11:30 AM. The meeting will be hosted by Bob and Diane May and their family at Swayze Inn Farm in Hope, NJ. We will have our general meeting, a farm tour and a session on participating in a breed up program including the use of CIDRs to cycle ewes, laparoscopic artificial insemination techniques and pregnancy check via ultrasound. As always dress comfortable and wear farm clothes. Meeting will be rain or shine and lunch will be served.

Our general meeting agenda will include an update on our Youth Ambassador program, an update from this year’s ASI meeting as well as a report out on last year’s festival along with the plans for this year which is our 25th annual festival. For members in attendance we will have our ever popular door prize drawings at the end of the meeting.

The May’s Swayze Inn Farm is located in Warren County, NJ and the address can be found in the Member’s Directory.  Bob’s email address is newjerseyjacobs@yahoo.com and the farm’s website is SwayzeInnFarm.com.

This is an opportunity to meet the new slate of officers and interact with other regional shepherds in addition to learning about some breeding practices and experiences from seasoned breeders and a veterinarian who is a reproduction specialist.

We would like to get a head count for lunch so please let Bob know if you will be attending as well if you may have any food allergies.

Look forward to seeing you at the meeting.

Cheers,

Kevin M.

A swarming, exotic tick species is now living year round in N.J.

An exotic species of tick that mysteriously appeared in New Jersey last year is now here to stay.

The New Jersey Department of Agriculture announced Friday that the East Asian tick, also known as Longhorned tick or the bush tick, which was discovered on a Hunterdon County farm last year, has survived the winter.

“Ongoing surveillance continued during the winter and on April 17, 2018, the National Veterinary Services Laboratory confirmed the Longhorned tick successfully overwintered in New Jersey and has possibly become established in the state,” it was stated in a news release.

Last summer, a farmer walked into the Hunterdon County health office covered in thousands of the ticks after she was shearing a 12-year-old Icelandic sheep named Hannah. Experts were called in to identify the tick which was not previously known to exist in the United States. The Department of Agriculture says it still does not know how the tick made its way to New Jersey.

The sheep has never traveled internationally and has rarely left Hunterdon County, according to Andrea Egizi, a tick specialist at the Monmouth County Tick-borne Disease Lab.

When the incident was first reported, steps were taken to eradicate the insect from the farm by using a chemical wash on the sheep and removing tall grass where the they are known to dwell. The exact location of the farm and the identity of the sheep farmer is being withheld by the New Jersey Department of Agriculture.

Although the ticks are known to carry diseases, such as spotted fever rickettsioses in other parts of the world, tests performed on the ticks and the farm animals were negative for diseases.

Local, state and federal animal health and wildlife officials, as well as Rutgers University – Center for Vector Biology, are working together to eliminate the ticks and stop them from spreading. Wildlife and livestock in the area will continue to be monitored throughout the year.

The ticks are known to swarm and infest deer and animals other than sheep, so the department is warning that it has the potential to infect other North American wildlife species. The ticks reproduce asexually by cloning themselves and just one of them is capable of laying thousands of eggs.

State and federal Department of Agriculture employees will be working with the public to determine if the tick has spread and to educate the public about protecting their livestock and pets from the pest.

The nymphs of the ticks are very small, resemble small spiders and are easy to miss, according to the Department of Agriculture. They are dark brown, about the size of a pea when full grown and can be found in tall grasses.

Authorities are asking people to contact the state veterinarian at 609-671-6400 if they see any unusual ticks on their livestock.

Unusual ticks detected in wildlife should be reported to the New Jersey Division of Fish and Wildlife, Bureau or Wildlife Management at 908-637-4173, ext. 120.

Any questions about tick-borne illness in humans should be directed to local health departments or the New Jersey Department of Health at 609-826-5964.

Scrapie Program Update – Samples Needed for State Sampling Quota

At the most recent General Meeting Dr. Linda Detwiler provided an update on the USDA scrapie program and the need for collecting samples from Sheep that are over 18 months old that die in order to meet the state sampling quota. Owners that allow for samples to be collected will be eligible for the free scrapie tags with your farm’s assigned premise ID. The importance of this program can not be overstated. If we are able to collect enough data from the scrapie monitoring program over the next few years, we may be able to declare the U.S. scrapie free which would open up a number of opportunities for U.S. Sheep producers.

From APHIS website:

Since slaughter surveillance stared in FY 2003, the percent of cull sheep found positive at slaughter (once adjusted for face color) has decreased 90 percent. However, in order to declare the U.S. “scrapie free”, we must be able to prove to the world that we have conducted testing in all sheep and goat populations. This is why your submission of samples from sheep/goats over 18 months of age found dead or euthanized on your farm is extremely important. Without your help, we will not be able to declare the US free of scrapie, costing the sheep and goat industries approximately $10 to $20 million, annually.

Evaluation of chemical castration with calcium chloride versus surgical castration in donkeys: testosterone as an endpoint marker

Abstract

Background

For the last few years, researchers have been interested in developing a method for chemical sterilization which may be a better alternative to surgical castration. An ideal chemical sterilant would be one that effectively arrests spermatogenesis and androgenesis as well as libido with absence of toxic or other side effects. Calcium chloride in various solutions and concentrations has been tested in many animal species, but few studies have been evaluated it in equines as a chemical sterilant. So, the objective of this study was to evaluate the clinical efficacy of chemical castration with 20 % calcium chloride dissolved in absolute ethanol in comparison with surgical castration in donkeys based on the changes in the serum testosterone level and the histopathological changes in treated testes.

Methods

Twelve clinically healthy adult male donkeys were used in this study. Donkeys were divided randomly and equally into two groups: a surgical (S) group (n = 6) and a chemical (C) group (n  = 6). Animals in the (S) group were subjected to surgical castration while those in the (C) group received a single bilateral intratesticular injection of 20 % calcium chloride dissolved in absolute ethanol (20 ml/testis). Animals were kept under clinical observation for 60 days. Changes in animals’ behavior and gross changes in external genitalia were monitored daily. Serum concentrations of testosterone were measured prior to treatment and at 15, 30, 45 and 60 days post-treatment. Testicles in the (C) group were examined histopathologically at the end of the experiment.

Results

Chemical castration with intratesticular calcium chloride vs. surgical castration failed to reduce serum concentrations of testosterone throughout the whole duration of the study; however it induced orchitis that was evident by focal necrotic areas in seminiferous tubules, cellular infiltration of neutrophils, proliferative intertubular fibrosis with a compensatory proliferation of Leydig cells. Donkeys tolerated the intratesticular injection of calcium chloride. There were no detectable changes in the general health status of the animals with the exception of swelling in external genitalia, scrotal ulcerations and fistulas. Food and water consumption and the gait of animals remained unaffected.

Conclusion

Intratesticular calcium chloride can’t be considered an effective method for chemical castration in donkeys.
