Sheep Diseases
Argentina – molecular biology to diagnose diseases of sheep
Biochemiq The company signed an agreement with the Animal Health Group of INTA Bariloche, by Carlos Robles, with the aim of identifying and facilitating the diagnosis by molecular biology adenomatosis, livestock disease with a high impact on Patagonia.
Lymphadenitis occurs in sheep and goat herds as a result of infection with Corynebacterium pseudotuberculosis. It is highly contagious and causes great losses. Read the rest of this entry »

For many academics and experts in animal nutrition, research on the nutritional needs of the “cow in transition” is the ultimate challenge in the field of nutrition of dairy cattle. This transitional period begins in late gestation and continues for several weeks in early lactation. Many consider it covers 2 to 3 weeks before calving and 2-3 weeks. In that short time, the cow is imposed abrupt changes:
- the difficulties inherent in late pregnancy and reducing its intake capacity
- parturition itself
- the onset of lactation
- fluctuations in food intake and appetite,
- change in diet (changing from a system of gestation to lactation diet),
- fluctuations in hormone levels. Read the rest of this entry »
Join those who fight against resistance antibiotic!
Introduction
What may be the link between sheep, antimicrobial resistance (AMR) and you? Let us remember how the world has been transformed after the commercial development of antibiotics, which are the most common form of antimicrobials. People do die more common infections. Yet four years after the introduction of penicillin in 1943, some strains of bacteria already had some resistance. Read the rest of this entry »
The posthitis leukosis in sheep
It must first address the issue. Like many diseases that we see in sheep, the posthitis leukosis is the result of an interaction between a bacterium and some other factor. The bacterium is Corynebacterium renal or that group. These bacteria have the ability to decompose urea with an enzyme, unease. The other factor is an increase in protein levels of the regime, a factor quite common in the months preceding breeding to improve the state of rams. Once the protein in the diet from all sources exceeds 16 per 100, urine may contain more than 4 per 100 of urea. This excess of urea makes the urine alkaline. Read the rest of this entry »
Epididymitis in sheep
This disease is not caused by different strains of one bacterium, but by two different bacteria causing symptoms almost identical in rams. In Western Canada, the main bacteria involved are Brucella ovis and Actinobacillus seminis. In Ontario, there were very few isolates of B. ovis epididymitis but is still a problem. In this province, the bacterium that is the supposed cause is Actinobacillus seminis. However, the result is the same, a chronic infection of the epididymis and testes to lower fertility of the ram.

Spider Syndrome – Recessive Gene
Historically several factors have led researchers to decide that Spider Syndrome is genetically transmitted as an autosomal recessive gene. Read the rest of this entry »
Spider Syndrome – Diagnosisp
A correct diagnosis is absolutely essential so that the exact problem is known and proper action taken. As an aid in correctly identifying Spider Syndrome lambs, SID has published Diagnosis of Spider Syndrome. Anyone involved in identifying a Spider Syndrome lamb should obtain a copy of this publication from SID so that the correct problem can be addressed. Read the rest of this entry »
Spider Syndrome
Introduction
One of the most controversial issues in purebred sheep circles is the Spider Syndrome. Problems clouding the issue have been accurate diagnosis of Spider Syndrome lambs, understanding how it occurs, differing terminology in regard to Spider Syndrome and a lack of knowledge of what to do about it.

Vaccination
Vaccination may reduce the number of animals (cattle, sheep and goats) that develop clinical disease. However, it has been shown that the vaccinated animal may still become infected and shed bacteria. There is no vaccine approved for sheep in the United States. Read the rest of this entry »
