Item Fontes de lipídeos associados à palma forrageira sobre as características sensoriais da carne ovina(2022-10-07) Nascimento, Thaís Fernanda do; Guim, Adriana; http://lattes.cnpq.br/5179137865818915; http://lattes.cnpq.br/5238680527935892The search for food that meets commercial and healthier requirements has created a greater search for meat of higher quality and nutritional value. In this paper, the goal was to evaluate the effect of diets with different lipid sources associated with forage palm on the sensory characteristics of sheep meat. The research included 39 male animals, without a defined racial pattern, castrated, 4 months old and an average initial weight of 22 kg. The experiment took place in the Department of Animal Science, sheep and goat farming sector of the Universidade Federal Rural de Pernambuco, located in Recife, Pernambuco. The treatments consisted of Tifton Hay and Forage Palm as forage, and ground corn, wheat bran and mineral salt as concentrate. In the experimental diet, cottonseed, corn germ and coconut cake were inserted in the concentrated feed. The animals were housed in individual suspended stalls, containing feeders and drinkers, distributed in a covered shed. The experiment lasted 60 days, with the first 30 days aimed at adapting the animals to diets, facilities and management. The last 30 days were devoted to data collection and evaluations. From the Longissimus lumborum muscle, the characteristics, sensory attributes and commercial value of sheep meat were evaluated. The diets utilized with lipid sources did not show significant differences in the sensory characteristics of sheep meat (P>0.05), showing a positive positioning of the evaluators regarding purchase intention, which makes it a good alternative for lambs in the termination phase.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 Carne: consumir ou não consumir? Eis a questão(2022-06-03) Silva, Talita Vitória Bezerra da; Souza, Andreia Fernandes de; http://lattes.cnpq.br/6354486109796073; http://lattes.cnpq.br/1515251211404048The dissemination of numerous unfounded information about meat consumption has led some people to erroneously claim that this activity is the main villain of global warming and scarcity of water resources, the increase in cardiovascular and associated diseases, in addition to mistreatment of production animals. Adopting veganism has been an alternative for those who says that want to stop the destruction of the environment, reduce the exploitation of animals and improve their quality of life. However, many of the arguments used by supporters of this lifestyle are unfounded and without scientific evidence. Today, sustainable livestock farming is already a reality seen on many farms and most of the meat sold in large urban centers comes from slaughterhouses that meet animal and environmental welfare standards; research shows that the consumption of animal proteins is essential for human nutrition and the diseases associated with consumption are related to the quality of the meat and the way it is prepared. Therefore, we will start this study by bringing an overview of Brazilian livestock and how it has developed over the years, then points will be presented that show the importance of meat consumption from the first homids to the present day and the main deficiencies caused by animal protein-restricted diets. Subsequently, the most talked about points in relation to the production of animal proteins will be explained, such as: animal welfare, animal husbandry and the environment as well as the use of hormones and antibiotics in production. With a scientific basis, this work seeks to show the consumer that it is possible to eat meat in a healthy way, respecting animals and the environment.Item Ureia em substituição ao farelo de soja: características físico-químicas e sensoriais da carne ovina(2021-02-25) Medeiros, Nubia Maria Guedes; Soares, Luciana Felizardo Pereira; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/6850524310715861Feeding is a determining factor in the sensory characteristics of meat, with the aim of evaluating the influence of partial replacement of soybean meal with urea in diets with Mexican elephant ear palm on the physical and sensory characteristics of sheep meat. Forty Santa Inês male sheep, 4 months of age and average initial weight of 22 ± 1.0 kg, were used, distributed in a randomized block design. The experimental diets consisted of Mexican Elephant Ear palm (Opuntia stricta Haw), tifton hay (Cynodon dactylon (L.) Pers), soybean meal (Glycine max (L.)), ground corn, urea and mineral salt. The treatments consisted of increasing levels of urea (0%, 0.8%, 1.6% and 2.4%) to replace soybean meal. The variables analyzed were: determined physical attributes, such as shear force, color, water retention capacity and cooking weight losses, chemical parameters (moisture, protein, lipids and mineral matter) and sensory aspects of color, aroma, flavor, softness, juiciness and global 9 acceptance of sheep meat. The levels of substitution of soybean meal for urea did not influence the chemical characteristics, pH, water retention capacity, shear strength, color, allowed acceptable values in sensory attributes such as general appearance, color, characteristic sheep aroma, strange aroma, tenderness, juiciness and characteristic sheep flavor (P> 0.05), while increased levels provided less cooking loss (P <0.05) and less strange flavor (P <0.05) in physical and sensory characteristics, respectively. It is recommended to replace soybean meal with up to 2.4% urea in diets for sheep as it does not alter the physical, chemical and sensory characteristics of the meat product, making it an alternative source of protein synthesis.
