Researchers work in a project to associate the production of rice with native fish farming in moments in which the producer has to leave the earth to rest. They estimate that good breeding results could be obtained and at the same time to nourish the soils for the future productive campaigns. The development of fish farming might favor the use of fertilizers and agrochemicals, which might help to get organic rice.
In a short time, nutrigenomics, which is a science which studies the relation of the genes with nutrition and incorporates the concept of metabolism, might permit to make important contributions to the quality of milk and meat of the different animal species we consume. Researchers carry out different experiences through this new discipline whose main aim is to improve nutrition and health and offer a more personalized nutrition.
Scientists analyze the almost unknown characteristics of the pichiciego, a strange specimen of armadillo found by chance in a rural road. It is of the same family than the tatú carreta, the mulita, the peludo, the Patagonic pichi and the pichi llorón. Among others, the pichiciego is a mystery for scientists because it is an endangered species with night habits, it lives in caves under the earth and it hardly ever comes out.
Scientists developed a technology which permits to take a biopsy of an embryo of only seven days and determine its sex before implanting it into the mother, whereas the embryos which are not of the desired sex are frozen to be sold or can be used in the production of mother cells. The first Argentinean filly was born, daughter of a champion and conceived by this technique.
The formula permits a higher performance and prolonged release of medicines in the application place to treat otitis in dogs. For its development Poloxamer was used, a copolymer which has thermo-reversible properties, that is, which is presented in liquid state at room temperature and facilitates its administration and gel states at the body temperature. The new compound is a cheap and practical choice for veterinary therapy.
The objective of a project carried out by Conicet researchers is to find a way to increase the reproductive capacity and form elite genetic nuclei in bovines, which could give an answer to the current commercial market exigencies. The new knowledge will impact in a positive way in the biomedical field, taking into account the current peak of assisted reproduction.
It is the biggest rodent in the world; it can weight more than 80 kg and live up to 10 years in captivity. Capybaras can be considered a significant natural resource, due to their meat, which is an important protein alternative, as well as for their delicate leather, used to produce leather goods and in upholstery. That is why a team of researchers analyzes the specie in its natural habit to evaluate captivity breeding.
In order to mitigate the blockade of fishes’ movement, Yacyretá dams have installations to facilitate their passage. Professionals carried out a study about the specific composition of fishes’ transferences in these installations, since 1999 to 2006. They recognized a total of 103 species which used the dam’s lifts and which were transferred from low water to Yacyretá Reservoir.
A team of researchers works in the experimentation to introduce sheep without wool in the region, aimed at the production of meat and which can be adapted to low productivity lands. It is estimated that it might be beneficial in economic terms given the good reproductive capacity of the sheep without wool and because, besides, it might increase the productivity of the current breeds.
It already weights 290 kilos and it is the first bitransgenic veal in the world, as it has two human genes and it is capable of producing milk similar to breast milk. It was born a year ago, its name is ISA and it was cloned by the UNSAM and the INTA Balcarce. The researchers who took part in the project highlight the importance of the achievement in the fight against infantile mortality and they are already working in a similar cloning project applied to goats.
One every of five professionals suffered at least a serious accident at work, whereas more than the 28% suffers or has suffered any zoonotic disease, such as brucellosis. Besides, veterinaries are exposed to suffer injuries, such as punctures, hematomas and bruises. The data, generated by a research work done in the UNL, evidenced that around the 75% of the physicians haven’t received any training about work dangers.
The use of laboratory animals for research constitutes a scientific and ethical matter, because it implies researchers, as well as technicians and students who work with experimentation animals, who are capable and trained in their adequate management and care. Facing the lack of law regarding this topic, some professionals are working in a law Project which already in the National Senate.
Researchers are analyzing sheep’s capacity to self-medicate. The animal behavior evidences that when they feel digestive discomfort caused by parasites, they select plants which contain tannins, which are beneficial for the health. Between the objectives of this research there are to obtain management guidelines to mix this kind of plants in the environment in order to optimize the productivity and animal welfare.
A study done on wild mice concluded that the infection with a pathogen has a great influence on the risk of having another infection. Scientists proved that the parasites of a specie are capable of setting a net in which they interact and influence each other altering the dynamics and distribution of diseases. So, the cause which explains the variability in the risk of infection with a parasite is the previous infection with another.
Researchers from the UNL study how to conserve avian blood with bacteria to be able to use it in the elaboration of balanced food for animals. In order to do that they elaborate from the isolation of some microorganisms a bioprotector cultivation which limits the action over the fermentation of damaging bacteria. By reusing avian blood as raw material, it reduces their environmental impact, given that it is a very contaminating waste because it demands a great amount of oxygen.
