Item Caracterização da ovinocultura de corte em regime de semiconfinamento no município de Belo Jardim – PE(2024-10-01) Silva, Emanuel Isaque Cordeiro da; Monnerat, João Paulo Ismério dos Santos; http://lattes.cnpq.br/3851426263880079; http://lattes.cnpq.br/8455592829863253The sheep meat production sector has established itself as an agro-pastoral activity of significant economic and social importance in Brazil, particularly in regions where the adaptability of sheep breeds to climatic conditions is notable. The semi-confinement system, characterized by a combination of grazing and controlled feeding, presents a viable alternative for sheep meat production, enabling better utilization of forage resources and contributing to the sustainability of the activity. In this context, the present study aims to explore the specificities of this practice in the city of Belo Jardim through a questionnaire designed and administered to local sheep producers. The objective is to collect data and characterize the sheep meat production system in semi-confinement, evaluating and discussing the productive and reproductive indices of the herd. Additionally, the study seeks to compare the productive data of one production system in the city to identify the potentials and limitations inherent in the production chain. Employing a methodological approach that includes quantitative data analysis, interviews with local producers, and direct observation, this research aims to understand management practices, adopted production systems, and the key factors influencing the profitability and viability of sheep meat production in Belo Jardim. It is anticipated that the results will contribute not only to strengthening the sheep production chain in the region but also to the formulation of public policies that promote the development of this activity.Item Validação de um protótipo de balança automática utilizando o sistema walk-over-weighning em ovinos(2019-06-18) Nascimento, Hugo Fernando Araújo do; Carvalho, Francisco Fernando Ramos de; http://lattes.cnpq.br/8552194153767195; http://lattes.cnpq.br/4011530135756687Given the importance of accurate and daily monitoring of individual body weight (BW), new investments have been made in research to find alternatives to static weighing (SW) based weighing systems. A key among these alternatives is the Walk-Over-Weighing (WoW) technology, where animals freely and spontaneously pass through an equipment that is strategically positioned to be attractive for spontaneous passages of animals without human assistance. The objective of this work is to analyze the performance of a prototype automatic scale that uses the WoW weighing concept. The prototype used in this research was designed by the researcher Eliel Gonzalez-Garcia (Institut National de la Recherche Agronomique - INRA) the scale is aimed at small ruminants and equipped with tag readers that use radiofrequency technology for accurate storage of BW data. This experiment was divided into two distinct parts that complement each other. The first part was performed during the spring period with 42 Lacaune ewes of different ages and physiological states that were weighed in a SW to obtain BW as reference body weight (RBW), all animals were spontaneously directed to WoW in an indoor system where each animal went through the automatic weighing scale three times, where the WoW body weight value (WBW) was obtained. This first phase was characterized as the calibration phase of the equipment and training of all the team involved and lasted for two hours. The second phase consisted of the use of 237 Romane sheep of different ages and physiological states. In the first experiment the prototype was exposed to the transition period between spring/summer and a larger number of animals, since in previous experiments (GONZÁLEZ-GARCÍA et al., 2018a) the maximum number of individuals used was 98 sheep. The animals remained for a period of 29 days in the pasture, exposed to WoW and with limited access to water and salt stones within the area of attraction. The Bland and Altman concordance analysis method and the Lin concordance correlation coefficient (CCC) were used to establish agreement, correlation and reproducibility between RBW and WBW records, with the objective of validating the use of prototype of the WoW automatic scale for accurate and reliable data collection of animals during the spring/summer transition period in southern France (LIN, 1989; ALTMAN; BLAND, 1986). The CCC was used to establish agreement between PCW and PCR records. The results show that after respecting the period of adaptation to the equipment, the animals show a decrease in unwanted behaviors and together with the treatment of the database aiming at eliminating discrepant data caused by unwanted behavior and/or external factors that may harm the data, the correlation, reproducibility and CCC presented values between 0.95 and 0.99, demonstrating a high correlation between the two methods.Item Comportamento ingestivo de caprinos e ovinos recebendo diferentes fontes de carboidratos associado à ureia em substituição ao farelo de soja(2018-08-22) Silva, Rita de Cássia Manso; Guim, Adriana; http://lattes.cnpq.br/5179137865818915; http://lattes.cnpq.br/0329511011280265Northeastern Brazil has a great ability to raise goats and sheep in the semiarid region, but there is a difficulty in homogeneous production of food during the year. The use of alternative food in feed that is adapted to the semi-arid climate, such as forage palm and manioc, can minimize the problem. The objective of this study was to analyze the effect of different sources of carbohydrates associated with urea in replacement of soybean meal on the ingestive behavior of sheep and goats. Four goats and four sheep with permanent fistula in the rumen were used, arranged in a 4x4 Latin square design, receiving the experimental diets with different sources of carbohydrates and urea replacing the soybean meal. The diets were composed of four treatments: a) corn and soybean meal, b) corn and urea, c) manioc and urea scrap, and d) forage palm and urea. Data were analyzed by analysis of variance and the means were compared by the Tukey test, at 5% significance. There was no significant difference (P> 0.05) in the ingestive behavior between goats and sheep. However, animals fed the diet containing manioc and urea showed a longer time in leisure (977.50 minutes / day), followed by the animals of the diets with forage palm and urea (845 minutes / day) corn + soybean meal (822.50) and corn + urea (821.25 minutes). The feeding and rumination efficiencies were not influenced by the animal species either by the diets. Thus, it is concluded that the association of energetic foods produced in the region (palm and manioc rasa) associated with urea does not compromise the ingestive behavior of goats and sheep.
