Background and objectives: The prevalence of zoonotic parasitic diseases in large and small ruminants, which provide an acceptable percentage of protein sources of animal origin, is significant. In the meantime, liver parasites have a special place, because they can cause a lot of economic losses...

Background and Objective: Dogs are associated with more than 60 types of common diseases with humans, among which parasitic diseases play an important role in public health. This study aimed to estimate the frequency of gastrointestinal helminths fauna among dogs in Gorgan, Iran. Methods: This...

Introduction: In most parts of the world, poultry are exposed to mycotoxins-containing foods. Aflatoxins are the most common mycotoxins formed primarily by the fungus Aspergillus. Fungi that produce aflatoxin can grow and multiply on different materials and under different conditions of humidity,...

Introduction: To be successful in rearing newborn calves, it is necessary to maximize feed efficiency and health status. One way is to use feed additives such as probiotics. Probiotics reduce the harmful microflora of the digestive tract (such as coliforms) and metabolic and infectious diseases and ...

Introduction: The main factors limiting the consumption of low-quality fodder is their low nitrogen. Therefore, it is often difficult to provide sufficient nutrients, especially energy and protein for ruminants, which use these resources. Deficiency of nutrients in low quality forage also affects...

Introduction and Objective: High concentrated diets are rapidly degraded in the rumen and lower ruminal pH by rapid and high lactic acid production. The use of chemical or biological buffers improves digestion and fermentation conditions in a high concentrate diet. The aim of this study was to...

Low feed efficiency is one of the problems in the rumen of ruminants, which results in reduced growth and production of livestock and, most importantly, environmental pollution due to the release of methane and nitrogenous compounds. Changes in ruminal fermentation can be made to improve...

Ichthyophthirius multifiliis is one of the most important ectoparasites in ornamental fish causing economic losses. Although many different methods are being applied to reduce the prevalence of the disease but it is recommended to adopt preventive methods such as using immune stimulative materials...

Introduction: Pastures provide an important part of ruminant fodder needs, and farmers store some pasture plants to use in winter-feeding of livestock. Therefore, having enough information about the nutritional value of such plants can help to optimize their consumption in animal feeding....

Introduction: The use of highly concentrated rations in the fattening of ruminant animals is done to improve the performance per unit of feed consumption. Increasing the amount of concentrate in the ration improves the food conversion ratio and the weight gain of fattening lambs, and the production ...
