Last spring, it was reported that ivermectin had efficacy (in a laboratory setting) against the coronavirus that causes Covid 19. Ivermectin is an anti-parasitic drug for animals. Ivomec® drench is FDA-approved for use in sheep. Ivermectin also has approved uses for humans.
After the announcement, some people started using ivermectin to self-medicate. In some countries, a “black market” emerged for ivermectin. In the US, ivermectin started disappearing from the shelves of farm stores.
Many health officials oppose the use of ivermectin to treat Covid. Others advocate for its use and have used it to treat Covid patients. The appeal of ivermectin is that it is widely available and cheap. It is also usually well tolerated.
We would like to inform you that the 10th International Sheep Veterinary Congress (ISVC) that was scheduled to be held in 2022 from September 19th to 23rd, in Seville, together with the 5th Congress of the ECSRHM, will be delayed six months, to March 6 to 10, 2023. As it is known, the ISVC is being organized by the Spanish Society for Sheep and Goat Production (SEOC). The organizing committee has been working hard for several years in order to perform a successful conference at the organizational, content (scientific, cultural and recreational aspects) and attendance (delegates and speakers) levels.
The reason that has led us to make this decision has been the postponement of the 31st World Buiatrics Congress (WBC) 2021-MADRID, to September 4-8, 2022. The situation caused by the COVID-19 pandemic has forced the organizers (the Spanish Society ANEMBE) to postpone the conference to September 2022.
As we said before, we would like to have a successful ISVC congress, and as you know, although the WBC is a congress eminently dedicated to cattle, it also has a section dedicated to small ruminants. The WBC is an event with which we share delegates, speakers and members of the Scientific Committee, so it is likely that by holding both events at such close dates, many potential participants, would be forced to choose between the two congresses, negatively affecting both the number of attendees (delegates) and the quality (speakers). We also share sponsor companies and institutions, so holding both congresses in the same year and in the same country, would negatively affect their financial support to our congress. For these reasons, after taking into account the opinions of the members of the Organizing and Scientific Committees of the ISVC-Seville, and obtaining the ISVA and ECSRHM approvals, we considered postponing it to March 2023 to be the best option. If this postponement could cause inconvenience to any delegate, we sincerely apologize on behalf of all the organizers.
We also want to communicate, that we have decided, together with the ISVA, to organize a virtual meeting from 23rd to 25th November 2021 of which we will inform you soon.
Looking forward to meeting all you in March 2023 in Seville!!

Haemonchus contortus is a critical parasite of goats and sheep. Infection by this blood-feeding gastrointestinal nematode (GIN) parasite has significant health consequences, especially in lambs and kids. The parasite has developed resistance to virtually all known classes of small molecule anthelmintics used to treat it, giving rise in some areas to multidrug resistant parasites that are very difficult to control. Thus, new anthelmintics are urgently needed. Bacillus thuringiensis (Bt) crystal protein 5B (Cry5B), a naturally occurring protein made by a bacterium widely and safely used around the world as a bioinsecticide, represents a new non-small molecule modality for treating GINs. Cry5B has demonstrated anthelmintic activities against parasites of monogastric animals, including some related to those that infect humans, but has not yet been studied in a ruminant. Here we show that H. contortus adults are susceptible to Cry5B protein in vitro. Cry5B produced in its natural form as a spore-crystal lysate against H. contortus infections in goats had no significant efficacy. However, a new Active Pharmaceutical Ingredient (API) paraprobiotic form of Cry5B called IBaCC (Inactivated Bacterium with Cytosolic Crystals), in which Cry5B crystals are encapsulated in dead Bt cell wall ghosts, showed excellent efficacy in vitro against larval stages of H. contortus and relative protein stability in bovine rumen fluid. When given to sheep experimentally infected with H. contortus as three 60 mg/kg doses, Cry5B IBaCC resulted in significant reductions in fecal egg counts (90%) and parasite burdens (72%), with a very high impact on female parasites (96% reduction). These data indicate that Cry5B IBaCC is a potent new treatment tool for small ruminants in the battle against H. contortus.
WASHINGTON, December 9, 2020 — The U.S. Department of Agriculture's Agriculture Research Service (ARS) today announced a groundbreaking treatment that prevents anemia, weight loss, poor wool and meat production, and even death in sheep.
ARS researchers partnered with Virginia Tech and the University of Massachusetts' Medical School to solve H. contortus parasite infection, which also happens to be the number one health problem in the U.S. sheep industry. The parasite infects the stomach of ruminant mammals, feeding and interfering with digestion, before ultimately affecting the animal's overall health and stability.
"The H. contortus parasite has developed resistance to virtually all known classes of anti-parasitic drugs," said ARS Researcher Dr. Joseph Urban, who lead the research team in testing and implementation of a para-probiotic treatment to kill the parasite that causes H.contortus.
The worm parasite mates within the animal and its fertilized eggs pass through the animal's waste into the soil. The larvae then develop to re-infect other unsuspecting animals, spreading the infection throughout a pasture and creating a cycle of infection that hinders animal growth, development and production.

The High Prolificacy Breed Palas was formed over nine stages, during almost three decades by intricate crosses between the Romanov, Friesian, Finnish Landrace, Border Leicester, Ile de France and Palas Merino breeds. The desired type was obtained in 1989, and its genome consists of 39% genes from Romanov, 28% genes from Merinos, 16% genes from Friesian, 9% genes from Border Leicester, 6% genes from Ile de France, and 2% genes from Landrace Finnish. This population of sheep was reproductively isolated (CIR + 1,0) since 1989, and is bred at ICDCOC Palas Constanța.
In Dobrogea, at Research Development Institute for Sheep and Goats Breeding Palas – Constanța, there are 1,000 heads of sheep and 2,000 in another farm in the area.
External (morphological) characteristics
The body format of the breed is mesomorphic to dolichomorphic, with a fine, strong skeleton and correct aplomb. The head is broad, medium in size, and has a straight profile in ewes and slightly convex in rams. The ears are medium in size, worn laterally, and both sexes are hornless. The neck is suitably long, worn horizontally, and is well attached to the trunk; the trunk is long, with medium width and depth dimensions.
The color of the wool is white, the coat has no colored fibers, and the hair on the face and limbs are white; the wool is semi-fine, some specimens having fine wool.
The udder has a globular shape, of medium to large size, the nipples being suitably long, worn vertically or slightly laterally.
Prolificacy primiparous, 136-140 %
Multiparous, 150-160 %
Using of the breed
The new breed contributes to achieving a priority objective in the current economic context, namely, increasing meat production by producing three-stage meat hybrid lambs. The breed produces rams which, by mating with Merino-type sheep, determine the production of prolific F1 “halfbreed” hybrid ewes (in the first stage) and which, by mating with rams, from meat breeds, produce hybrids meat lambs (second stage).

The breed was formed at the Research and Development Institute for Sheep and Goats Breeding Palas – Constanța between 1975 and 1987. They were developed by crossing East Friesian (imported from Germany) and Awassi (imported from Israel) breeds with the Merino de Palas breed, followed by isolation reproductive and selection to increase milk production. The breed was homologated in 2010.
Currently, the Milk Breed Palas has in the genome 65% genes from two of the best milk breeds in the world – East Friesian and Awassi, with 27% of genes from Palas Merino breed raised in Dobrogea, and 8% genes from other breeds of minor importance.
In Dobrogea, at the Research and Development Institute for Sheep and Goats Breeding Palas – Constanța, there are 1,000 sheep, with 200 rams produced annually, to improve milk production in ewes farms located in the Dobrogea area.
The only genetic fund of the breed is found at the Research and Development Institute for Sheep and Goats Breeding Palas – Constanța. The population is structured in 12 ram families in the breeding season, proceeding the rotational mating between families.
External (morphological) characteristics
The conformation is specific to dairy sheep. A long head with a convex profile is more pronounced in males. They are hornless, the ears are large, covered with short, thick white hairs, and are carried laterally with a tail well attached to the trunk. The chest is long and deep with a small sternum prominent, while the trunk is elongated, has a trapezoidal shape, and the spine is rectilinear. The croup is relatively broad, long, and straight; the tail is thin and long, covered with white, thick short hairs. The udder is well attached, has a globular shape, is sparsely haired, with long nipples, suitably thick, directed sideways and downwards.
