Item Avaliação do fluxo sanguíneo do folículo ovulatório e corpo lúteo de fêmeas bubalinas por ultrassonografia Doppler(2024-09-27) Farias Júnior, Francisco Timbó; Batista, André Mariano; http://lattes.cnpq.br/5615914349535394; http://lattes.cnpq.br/7562129132084802The Mandatory Supervised Internship (ESO) is an essential part of the training of a Veterinary Doctor, being a mandatory requirement in the Veterinary Medicine course at UFRPE. With a workload of 420 hours, the internship was conducted at the Laboratory of Biotechniques Applied to Reproduction (LBR), between 04/01/2024 and 06/14/2024. The focus was on improving reproductive biotechnology, with emphasis on the in vitro maturation of oocytes and the development of an article based on research carried out with Murrah buffaloes. The study evaluated the blood flow of the ovulatory follicle and corpus luteum using Doppler ultrasound, correlating these data with reproductive efficiency. In the laboratory, activities such as in vitro maturation of bovine oocytes (IVM) and evaluation of meiotic progression using epifluorescence microscopy were carried out. Under the guidance of Professor Dr. André Mariano Batista and supervision of Professor Dr. Cláudio Coutinho Bartolomeu, the internship provided a practical insights into reproductive biotechnologies and their impact on reproductive efficiency in buffaloes.Item Carne de búfalo: produção, consumo e características nutricionais(2022-10-07) Silva, Maria Vitória Gomes da; Pessoa, Ricardo Alexandre Silva; http://lattes.cnpq.br/0245806512931662; http://lattes.cnpq.br/3205016641166474This study aimed to address the production, consumption and nutritional characteristics of buffalo meat. The history of buffalo farming, the introduction and dissemination of buffaloes in the Americas was addressed, with a focus on Brazil, as well as talking about its production in the northeast region and in the state of Pernambuco. The meat production scenario and its obstacles, consumption and strategies to leverage its productivity were presented. Because the qualities of buffalo meat are undeniable, the product shows superior quality when compared to similar species, however, the consumption of meat is still not so widespread, since there is a stigma related to meat, where it is seen by many as a inferior quality product. So, using marketing strategies to promote its nutritional characteristics is an alternative that can boost the search for the product and, therefore, its production.Item Búfalo (Bubalus bubalis): pontos que destacam a importância da espécie como animal de produção(2022-10-07) Teixeira, Maria Victoria Viegas de Morais; Pessoa, Ricardo Alexandre Silva; Nascimento, Júlio Cézar dos Santos; http://lattes.cnpq.br/4343017315156292; http://lattes.cnpq.br/0245806512931662; http://lattes.cnpq.br/9414229185488577This present literature review sought to highlight the history of the buffalo, during its introduction and subsequent settlement in all regions of the world, in addition to emphasizing some important characteristics of the buffalo species, characteristics that differentiate them from other species, such as their rusticity, docility and high adaptive capacity to the diverse adverse environments of Brazil and the world. Even with the attributes that the buffalo has, it is still undervalued and unknown by much of society. Undervalued by the producer market, which sells much of the meat of this animal as being of the bovine species and undervalued and unknown by many people who do not even know or have consumed any product from them and hear and spread false comments about this species. From this, arose the desire to approach this topic, seeking to add reliable information to make the reader have more knowledge and end his disapproval of the species.Item Relatório de Estágio Supervisionado Obrigatório(2021-03-05) Matos, Yasmin Caroline da Silva; Souza, Andreia Fernandes de; http://lattes.cnpq.br/6354486109796073; http://lattes.cnpq.br/4404627710797961Item Relatório de Estágio Supervisionado Obrigatório(2021-12-12) Soares, Raquel Cristina Carvalho; Pessoa, Ricardo Alexandre Silva; http://lattes.cnpq.br/0245806512931662; http://lattes.cnpq.br/1279928414920644Item Correlações entre parâmetros obtidos por meio de ultrassonografia e na carcaça de novilhos bubalinos terminados em confinamento(2021-12-03) Vieira, Guilherme Heliodoro Pedroso; Pessoa, Ricardo Alexandre Silva; http://lattes.cnpq.br/0245806512931662; http://lattes.cnpq.br/8840572890087004In order to evaluate the correlations between measurements determined in vivo by ultrasound and in the carcass of feedlot-finished buffalo steers, the experiment was carried out in the Buffalo Culture Sector of the Animal Science Department of the Federal Rural University of Pernambuco. Twenty whole buffalo Murrah steers were used, with an initial average weight of 300 kg, collective in individual pens. Feeding was confirmed by sugarcane corrected with urea and small palm (Nopalea cochenillifera) with urea, replacing wheat bran, and ad libitum approval, at 06:00 and 18:00, allowing about 10% of the leftovers. After the 80 days, experimental measures were carried out with measurements of the ribeye area (AOLU) and subcutaneous fat thickness (EGSU) by ultrasound. Afterwards, the animals were introduced to fasting for 16 hours and slaughtered to obtain the carcass. In the cold carcass, between the 12th and 13th ribs, AOLC and EGSC were measured. The experimental design adopted was in randomized blocks with four treatments. Pearson's correlation was performed between measurements determined in vivo by ultrasound and in the carcass of Murrah steers, accepting up to a level of 5% precision. Ultrasound-measured AOLU was highly correlated with carcass-measured AOLC (0.96) and carcass compactness index (0.87) selected on carcass (P<0.001). Ultrasound-measured EGSU showed high correlation (P < 0.001) with carcass EGSC (0.94) and low but slight correlation (P < 0.05) with ICC (0.48) and AOLC (0.48) chose on the carcass. AOLU and EGSU measurements adjusted by ultrasonography can be used in the evaluation of these parameters in the carcass.
