Journal of Dairy & Veterinary Sciences - Juniper Publishers   Introduction Since radioactivity was first discovered, there has been concern regarding the damage that it might pose to humans, living creatures and the environment. Many studies have been dedicated to monitoring amounts of radionuclides’ activity in food and nutritional supplements, particularly related to the human diet, seeking to determine the risks those amounts may bring [ 1 - 3 ]. Measured feeds were all developed from a base of soy, wheat, corn fibers, sodium chloride and a vitamin complex called ("Vitamin Mineral Premix”). Thus, in these feed samples one must account for the natural radioactivity present in corn, wheat and soy, for example. Plants are primary receivers of radioactive contamination. The absorption of radionuclides from soil depends not only on their physiology but also in the processes that occur in there [ 4 ]. However, due to the difference in mo...

Journal of Dairy & Veterinary Sciences - Juniper Publishers     Introduction Polydactyly is a well studied congenital deformities observed in newborns that may involves the presence of more than the usual number of digits mainly in the upper extremities. In animals, this condition is recorded in several species such cats, dogs, guinea pigs, fowl, tortoises and birds [ 1 - 3 ]. It is important to note that each species has its own unique characteristics and different modes of inheritance. Polydactyly in the cat is most similar to that seen in the fowl, with exception of the mirror imaging seen in the latter [ 3 ]. In birds, this anomaly is caused due to the expression of a dominant autossomicalel [ 4 ] being recorded in chicken and rapine birds [ 3 - 5 ]. The greater rhea, Rhea Americana, is a common species in Brazil. Five subspecies are recognized being Rhea Americana intermedius those found in wild population from southeastern Brazi...

Journal of Dairy & Veterinary Sciences - Juniper Publishers     Introduction Tuberculosis is a serious infection in bovine, usually of the lungs, caused by the bacteria Mycobacterium bovis. This is a serious public health problem in many regions of the world, including Southeast Asia and Africa. A Purified Protein Derivative (PPD) skin test is a test that determines if Bovine suffers from Tuberculosis (TB). When TB infects Animal body, it becomes extra sensitive to certain elements of the bacteria, such as the purified protein derivative. A PPD test checks Bovine body’s current sensitivity, which will tell whether or not Bovine have TB [ 1 ]. Bovine tuberculosis infection in cattle is usually diagnosed in the live animal on the basis of delayed hypersensitivity reactions. Infection is often subclinical; when present, clinical signs are not specifically distinctive and can include weakness, anorexia, emaciation, dyspnoe...

Journal of Dairy & Veterinary Sciences - Juniper Publishers Introduction Initially developed for answering to military needs: desalination of sea water for sailors or uranium isotope enrichment, membrane technologies: ultra filtration (UF), microfiltration (MF), nano filtration (NF), reverse osmosis (RO) was then implemented in numerous industrial fields. Our research team has largely participated to insert them in many operation units of dairy technology. In this short review, we will rapidly describe the main applications of uses of UF in cheese-making and in whey treatment, developments of MF for removing microorganisms from raw milk and for separating casein micelles. For each of the chosen examples, the requested knowledge in Dairy Science which was necessary to acquire for optimizing the application will be evocated. Finally, progress in human nutrition made feasible by membrane technologies will be also shortly reviewed. UF in dairy technology Use of UF was sim...
