The cattle industry in Israel is exposed to a number of significant climate risks, some of which are already being felt today and are expected to worsen in the coming years: 1. Extreme heat loads The greatest risk to cattle in Israel. * Cows eat less. * The growth rate of calves decreases. * Milk production decreases. * Fertility is impaired. * The risk of disease and even death increases in extreme cases. In Israel, there are sometimes dozens of days a year when the heat loa

During the hot summer months, the goal is to maintain egg quality from the moment it is laid until it reaches the consumer. High heat damages the internal quality of the egg, increases moisture loss and increases the risk of bacterial growth. 1. Egg collection * Collect more frequently than in winter (at least 4–6 times a day in manual coops). * Take special care to collect in the early morning. * Do not leave eggs on collection conveyors or in trays exposed to heat. * Remove

Cows and calves have several main types of parasites, and they are divided into internal parasites (in the intestines, lungs, liver) and external parasites (on the skin). 1. Internal parasites (worms and protozoa) Intestinal worms (nematodes) Very common in young calves, causing: * Diarrhea * Weight loss * Loss of appetite * Rough coat/hair * Anemia and weakness Examples: Haemonchus contortus Ostertagia ostertagi Cooperia Treatment: * Deworming with medications such as iverme

Fowl Adenovirus (FAdV) is a group of viruses that mainly affect broiler, breeding and turkey poultry. The virus is present almost worldwide, and in recent years has caused significant outbreaks even in modern poultry houses due to high density, stress and weakened immune systems. What diseases does it cause? The virus can cause several main syndromes: 1. Inclusion Body Hepatitis (IBH) The most common disease in young broiler poultry. Signs: * Sudden death * Apathetic birds *

There are several key and proven ways to effectively increase the weight of chickens in broiler houses — but it is important to do so in a balanced way so as not to harm the health of the chicken, mortality rates, flock uniformity and feed conversion ratio (FCR). 1. Genetics and the chicken line The foundation begins with choosing a quality breed of broiler: * Cobb-Vantress – Cobb lines * Aviagen – Ross lines Genetic differences can significantly affect: * Growth rate * Feed

In recent years, and especially following outbreaks of H5N1 avian influenza worldwide and in Israel, the poultry sector has undergone a technological revolution aimed at early detection, rapid isolation, and reduction of economic and health damage. In Israel, where the poultry industry is one of the largest and most densely populated in the world relative to land area, there is enormous interest in prevention and control technologies. The new technologies are divided into sev

Eye diseases in cows and calves are relatively common, especially in conditions of crowding, dust, flies or mechanical damage. Here is a clear overview of the main ones, how to recognize and what to do: The most common eye disease – Pink Eye Professional name: Infectious Bovine Keratoconjunctivitis Cause: A bacterium called Moraxella bovis Signs: * Excessive tearing * Blinking / closing the eye * Sensitivity to light * Cloudiness or white spot on the cornea * In severe cases

Muscular dystrophy in calves is often called White Muscle Disease (in Hebrew: “White Muscle Disease”). It is a nutritional disease that is common, especially in young calves. What causes the disease? The main cause is a lack of: * Vitamin E * Selenium These two components are essential for protecting muscle cells from oxidative damage. When they are lacking, the muscles begin to break down and atrophy. Clinical signs in calves The disease can appear in different forms: Mild f

The disease that causes the most losses in fattening farms in the world If you had to choose one disease that really “sucks money” out of feedlots around the world, the finger would most likely point to Coccidiosis Coccidiosis is a parasitic disease of the digestive system that is considered the largest cause of economic losses in the global poultry industry. Although it is a well-known and “old” disease, it continues to cause enormous damage – mainly because of the difficult

Mastitis in dairy cows is one of the most common and significant diseases in the dairy industry, affecting both the health of the cow and the quality and quantity of milk. What is mastitis It is a bacterial infection of the udder, most often caused by: • Streptococcus • Staphylococcus • E. coli Symptoms can include: • Swelling, warmth, and pain in the udder • Change in the appearance of the milk (lumps, blood, watery) • Decrease in milk yield Cephapir

Toxin problems in dairy farms are a major issue in cattle herd health, primarily because of their direct impact on fertility, milk production, immunity, and mortality. The most common toxins are mycotoxins – toxins produced by fungi that grow in feed. Main types of toxins in dairy farms The mos t common toxins that are important to know: • Aflatoxins Are mainly formed in corn and high humidity. Very dangerous – also pass into milk (Aflatoxin M1). • Zearalenone Harms

Foot-and-Mouth Disease is one of the most contagious and devastating diseases in the cattle, sheep and pig industries. A single outbreak can cause severe economic losses, farm closures and even export restrictions. Therefore, biosecurity is the first and most critical line of defense.
