Análise física da estrutura do tecido ósseo bovino

There are diseases in vertebrates associated with the structure of bone tissue that directly affect the locomotor system of the animal. Being a endoskeleton, the diagnosis of these diseases becomes difficult in vivo. The characterization of the physical structure of the bone tissue of healthy animals becomes a major tool in the diagnosis comparison of live animals. Thus, the objective of this work is to determine the average value of the key physical properties of the bone structure used in the clinical diagnosis, such as: bone density, porosity, and mass attenuation coefficient of 59.6 keV photons of bone tissue and bovine and equine check variations in these values. The samples were provided by the pathology department of the Faculty of Veterinary Medicine and Zootechny of Botucatu-SP, which are of one male equine and one female bovine animals, using the radio and metacarpus, together with these materials were supplied the historic them. They were withdrawn ten samples in cuts of 10cm over the bone . These samples were submitted to the wet method of immersion in water for the density, by the method of attenuation of gamma radiation of radioisotope 241Am, it is estimated the mass attenuation coefficient, and then were dried in the oven for determining the content moisture. In determining the porosity of the samples was tight ground, in order to obtain the density of particles. The results for the mass attenuation coefficient of gamma radiation to the levels of saturated humidity, environment humidity, dry humidity respectively 0289 ± 0039; 0286 ± 0040 and 0297 ± 0042. And the density of particles was 2.2691 g/cm3

Tratamento orgânico de resíduos de rúmen bovino

The organic wastes need to be adequately managed, in order to avoid the environmental pollution and damage to the public health. So, this work aimed to study the composting process using two methods: manual and mechanized, for the treatment of bovine ruminal waste. This residue is generated in large proportions during the bovine slaughter process, and it can lead environmental degradation and contamination, or even damage to the public health, when not treated. For the initial adjustment of the composting parameters, it was incorporated the residue of coffee husks. The manual composting system was done by the manually aerated piles, while the mechanized composting system was done in a reactor coupled to a compressor that enabled the aeration of the system. The proportions used in both systems were: 90% bovine rumen (R) and 10% coffe husks (CC); 85% bovine rumen and 15% coffe husks; 80% bovine rumen and 20% coffe husks. The parameters determined during the monitoring of the composting process were: temperature, pH, moisture, organic matter, ash, organic carbon, Kjeldahl nitrogen and C/N ratio. The results obtained during the monitoring of the piles and reactors presented similar behavior, except for the parameters Kjeldahl nitrogen and C/N ratio. When compared to the “Instrução Normativa no 25 de 23/07/2009 do Ministério da Agricultura, Pecuária e Abastecimento”, the organic produced composts with the best results were: pile 2 (85% R; 15% CC) and reactors 1 (90% R; 10% CC) e 2 (85% R; 15% CC)

Criopreservação de embriões bovino produzidos in vitro: estado da arte

In the last years, the embryo in vitro production for every domestic species and mainly for bovine has attained a notorius status. This reproductive biotechnical procedure associate with ultrasound-guided ovum pick up (OPU) has been more and more incorporated and spread in our cattle herds, ranking up Brazil already at the top of the list in number of in vitro embryo produced. Some significant advantages provided, such as the possibility of using the premature or pregnant animals oocytes, without necessarily requiring the use of hormonal treatment, to make it possible to generate pregnancy at a shorter period of time, the rationalization in the use of semen and optimization in the use of sexed semen were determinant factors for OPU/IVP to reach this outstanding position. Nevertheless, right now the possibility of IVP embryo cryopreservation, just now is the biggest impediment for maximizing the use of this biotechnology, due to both lack of efficient methods and low laboratory produced embryo cryotolerance. Nowadays, the most used methods of IVP embryo cryopreservation are: slow freezing and vitrification. Traditionally, slow freezing is still the most used methods for in vivo and in vitro produced embryo cryopreservation. However, more recently vitrification - although still not commercially used in large scale - has been presenting satisfactory results in IVP embryo cryopreservation, according to searches

Remoção de N-amoniacal em baixas concentrações de oxigênio dissolvido a partir do efluente de frigorífico bovino

This work aimed to develop a biological system for removal of ammonia nitrogen operating at low concentrations of dissolved oxygen. Thus, a biological upflow vertical reactor was built, in which the affluent pass through the support media until the top. Sludge from an anaerobic stabilization pond of a slaughterhouse unit in the city of Presidente Prudente - SP was used as inoculum. Initially the system operated in batch and afterwards in a continuous flow with different HRT. For feeding the reactor, an initial phases was adopted a synthetic culture media, described by Martins (2007), in order to establish the ideal conditions for the development of Anammox bacteria and subsequently, submitted to the system a slugde effluent of slaughterhouse. The results showed significant removal efficiency of N-NH4+, especially in the phase without recirculation of culture media, with an average of 71% removal, with the proportion of removal of N-NH4 +:N-NO2- average 1: 1,69. For the period of operation with effluent from the slaughterhouse, were not obtained satisfactory results, without confirmation of the proliferation of Anammox bacteria in the system, due to the high presences of organic matter in the same confirmed by high concentrations of COD
