Colostrum, life’s first food of mammals, is a complex mixture of nutrients secreted by mother’s mammary glands during the first few days of lactation and its impact on the health of the newborn has been known for a long time [1]. Bovine colostrums (BC), the “early” milk produced by cows during the first several days post-parturition, has an immunological and nutrient profile composition significantly different from “mature” milk [2]. In addition to macronutrients found in milk such as protein, fat, carbohydrate, and micronutrients including vitamins and minerals, BC contain growth factors, antimicrobial compounds, oligosaccharides, and immune-regulating constituents. Premature aging, diabetes, cancer, cardiovascular diseases are affected by immune system disorders [3]. Consumption of bovine colostrum’s glycoproteins may be a.....ReadMore

The increasing pressure of reducing the use of antibiotics as antimicrobial growth promoters for animals due to harmful residual toxicity effects of drugs observed in the food chain calls for alternative solutions to sustain the efficiency of current livestock production [2,3]. Among the potential alternatives is essential oil which has been found to be loaded with several bioactive chemicals, less toxic and free from residues [4]. According to [5], essential oils are complex mixtures of volatile compounds produced by living organisms and isolated by physical means only (pressing and distillation) from the whole plant or plant part of known taxonomic origin. The composition of essential oil in plants depends on plant species and its age, harvesting periods, methods of processing, geographical location and soil types [6-8]. Scientific repo.....ReadMore

Goats are the most important and beneficial animal for common rural people of India for their nutritious milk, delicious meat and leather. Goats are having huge potency to help the poor population of India as well as of rest of the world. Thus, at least for India, goats are regarded as “Poor Man’s Cow”. Despite of being such an economically beneficial animal, the health management of goats was mostly neglected by veterinarians for a long period of time. Further, goats are the ruminant short day breeders and seasonality in terms of reproduction and immunity is prevalent in this animal. Being the ruminant free grazing animals they are susceptible to different season bound diseases which are mainly caused by different viruses, bacteria and protozoan. Physiologically goats are very much similar to that of human particularly for gesta.....ReadMore

Uric acid, a waste product normally present in the blood which produce after the breakdown of purines. The condition when serum uric acid elevated [≥7mg/dl in male, ≥6mg/dl in female] is known as hyperuricemia. Elevated uric acid can form crystals in the joints that cause gout [1]. Hyperuricemia is the major cause of producing gout. About 85%-90% of people develop hyperuricemia because of under excretion of urate while its over production occurs in the body. Hyperuricemia is not the only cause of development of gout. Monosodium urate monohydrate crystals modulate in the joints in the presence of various nucleating agents like insoluble collagens, chondroitin sulfate, cartilage fragments and other crystals when the intra-articular fluid is dehydrated in low temperature [2]. Moreover, vitamin C is a water-soluble micro nutrient that has.....ReadMore

The varroa mite infestation is a serious cause of honeybee colony loss at a global level. The varroa mite population development in a honeybee colony throughout the year, usually measured as level of infestation, is the result of mite reproduction success and of some favouring factors. Its parasitism model which relies on honeybee capped brood for reproduction as well as the role of varroa mite as vector of viruses increase the negative impact on honeybee health. Thus, it is clearly a necessity to develop new treatment approaches to interrupt the mite’s life cycle, especially before winter honeybee rearing in order to protect it. Except for the formic acid, the substances used today, which generally treat the whole colony, target only phoretic mites found on adult honeybees. Using the formic and acetic acids’ rapid vaporization proper.....ReadMore
