Immune Support The immune system serves as a defense mechanism against pathogens that the cow may come into contact with. In the healthy cow, the immune system will prevent these pathogens from causing various diseases. However, the immune system can be weakened due to the increased stress caused by calving, lactation, and heat. Products OmniGen AFTechnical InformationOmniGen…
Milk Fever Milk fever, or hypocalcaemia, is when the dairy cow has lowered levels of blood calcium. Milk fever generally occurs within the first 24 hours post-calving, but can still occur two to three days post-calving. It can be either clinical or subclinical. Clinical milk fever includes both “downer” and “non-downer” cows with less than…
Frothy Bloat Frothy bloat occurs when the cow ingests legumes, protein rich spring grass or a diet high in concentrates. A stable foam forms within the rumen, the stable foam traps gas produced by normal fermentative processes, and the gas cannot be released by eructation. Frothy bloat is commonly seen when cows are turned out…
Liver Abscess Liver abscesses are seen in all ages and breeds of cattle wherever cattle are raised. They are most common in feedlot and dairy cattle fed rations that predispose to rumenitis. Cattle with liver abscesses have reduced production efficiency. Affected livers are condemned at slaughter, and adhesions to surrounding organs or the diaphragm may…
Calf Disease Among all animals present on a dairy farm, the highest mortality rates generally occur in baby calves prior to weaning. This is a statistic worth paying attention to when thinking in terms of total herd profitability. Chances are high mortality of replacement animals, impaired growth of calves, decreased milk production of chronically afflicted…
Heat Stress Heat is produced by essential bodily processes (metabolism) which include maintenance, growth and egg production. Heat production is affected by body weight, species and breed, level of production, level of feed intake, feed quality and, to a lesser extent, by the amount of activity and exercise. If the stocking density is too high…
Rumen Health Two things are vital to good rumen function: a healthy microbial population and a suitable pH (ideally above 6.5). Without these, the rumen becomes less and less efficient at digestion of feed. This leaves cows susceptible to health complications such as acidosis and laminitis. The rumen plays an essential role in a cow’s…
Antimicrobials – Cattle For almost century, antimicrobials have played a vital role in treating bacterial infections in humans and animals and, in doing so, have saved many lives. While there are many different groups of antimicrobials available to use e.g. penicillin, macrolides, fluoroquinolones, etc. the ability of bacteria to develop resistance to them is a…
Bloat Control Bloat is an overdistention of the rumenoreticulum with the gases of fermentation, either in the form of a persistent foam mixed with the ruminal contents, called primary or frothy bloat, or in the form of free gas separated from the ingesta, called secondary or free-gas bloat. It is predominantly a disorder of cattle…
