Aditivo à base de resíduo de mandioca e inoculante bacteriano para silagens de capim elefante BRS Capiaçu
(Universidade Brasil, 2021) Santos, Anderson Braun dos; Brennecke, Käthery
During dry periods, there is a drop in the availability and quality of pastures, the main source of food for ruminants in the country, which impairs animal productivity. The use of alternative additives such as agro-industrial residues can be used as additives in silage production. Therefore, the present study aimed to evaluate the fermentative profile, gas and effluent losses, chemical composition and in situ ruminal degradability of BRS Capiaçu elephant grass silage with an additive formulated based on cassava residue, bacterial inoculant Lactobacillus buchneri and urea. The experiment was conducted at the Federal Institute of Rondônia (IFRO), Colorado do Oeste Campus. For the preparation of the formulated additive, cassava residue was used, with moisture reduced to approximately 89% of dry matter. The dry material was mixed with urea and Lactobacillus buchneri. The proportion of 1% of livestock urea on the total weight of cassava meal was used. The inoculant used was Lalsil AS® with Lactobacillus buchneri composition at a concentration of 1.0 x 1011 CFU/g. The dose applied in treatments with the inoculant was equivalent to 1g of commercial additive per ton of natural forage matter. The inoculant and urea were mixed with 100g of cassava meal and this first portion was mixed with the total amount of additive used. The treatments consisted of the levels of inclusion of the additive in the silage, as follows: 0%, 5%, 10%, 15%, 20% and 25%. Thus, it was observed that the silages that did not receive the additive had less than ideal dry matter content. Inclusion levels of 5% and 10% provided adequate DM levels for BRS Capiaçu silage. For the variable gas loss (PG), pH and ether extract (EE), there were no significant differences between the inclusion levels. The NDF values decreased as the inclusion of the formulated additive was increased, results that ranged from 71% to 33.21%. The NDFi values obtained after 288 hours of ruminal incubation showed significant differences between treatments. A significant difference was observed for the mineral matter (MM) variable, the MM content of the formulated additive is lower than that of Capiaçu. The inclusion of the formulated additive in the BRS Capiaçu elephant grass silage linearly reduced the crude protein (CP) content in the additive silages. Thus, it can be concluded that the use of the additive in BRS Capiaçu elephant grass silage changed the parameters evaluated when compared to silage without the use of these additives, benefiting mainly in the reduction of effluents produced.

The environment in which horses are placed, especially those undergoing reproductive management, is an important aspect to be evaluated. Since reproductive processes can be influenced by well-being issues, disruptions in physiological factors caused by stress can interfere with reproductive performance. The objective of this study was to assess the influence of the collection room ambiance on the behavior, semen volume, and concentration of Quarter Horse stallions. The stallions used had weights ranging from 416 to 505 kg and ages within active sexual maturity, varying from 6 to 24 years, selected based on fertility index. The experimental design employed was a dependent paired-sample design with four stallions. Movements during mounting and dismounting were observed, with a chronological recording of copulatory behavior using a camera attached to a mobile device (Samsung, model SM-A107 M/DS, Galaxy A 10s). Parameters such as muscle contraction, tail movement, and pawing were documented by day, month, and time, with identification of each animal. This analysis was initially conducted at normal video speed, and subsequently, for confirmation, the video speed was slowed down to work with each behavior separately. The frequency (number) of each activity involved in the process and the elapsed time (in seconds) for each activity were recorded. These data were then correlated with the ambiance, assessed by local internal and external temperature, digital device (dry and wet bulb), wind speed, dew point, relative humidity, and black globe index. The model also considered semen volume and concentration. The results did not reveal any influence of the collection room ambiance on the behavior, semen volume, and concentration of Quarter Horse stallions.

The present work aimed to highlight the need, convenience and application of Information Systems, as well as their technologies, as a way of integrating, facilitating, managing and promoting interfaces of normative, legal and administrative operations of Foreign Trade, with emphasis in the export of animal protein, of Brazilian origin, involving the entire logistics and production chain. For the effective demonstration of such aspects, implementations and results, an Information System was used, where an application was developed whose purpose is to gather as much information about the export legislation for the producer, who is dedicated to the provision of services for exporting animal protein. For the creation of this application, the following programming languages were used: all combined: PHP, HTML, Java Scrips, CSS and bootstrap, functioning as a database, which when accessed, you can search for all relevant legislation the export of animal protein. In this way, the present work sought to highlight the fundamental aspects to the integration of the legislation pertinent to the export of animal protein aiming at the improvement of the export processes, from the slaughterhouse to the final international destination. With this, the research developed gives rise to the implementation of the export of animal protein based on the national legal system, facilitating the process of analysis at the source of the legislation.
Aprimoramento de sensor de ambiência para índices de conforto térmico em instalações de bovinos leiteiros

Agribusiness is one of the most prominent economic activities in Brazil, and cattle farming is one of the most representative of them, but there is still a need for advances for it to remain competitive. The biggest stressor in dairy cattle farming is the climate, more specifically the heat, which affects considerably the welfare of the animals. In this context, the environment influences the living conditions of an organism, and the climate and the ability to adapt are responsible for influencing the behavior of the animals. In order to determine the effects of heat stress on animals, indices of thermal comfort have been developed taking into account climatic and/or physiological variables, helping producers and researchers to find the best means to reduce the stress caused by heat and determine the best time for measures to be implemented in order to provide thermal comfort to animals. Among the indices proposed in the literature, the temperature-humidity index (THI) and the black globe temperature and humidity index (BGTHI) stand out. Regarding rural workers, among the several existing thermal comfort indexes, we can highlight the thermal discomfort index (TDI). In order to obtain an ideal thermal environment for cattle in warm climatic regions, it is necessary to adequately monitor the environment to provide welfare to production animals and to achieve satisfactory zootechnical performance. In this sense, precision dairy farming, a management system based on information technology, enables greater control of animal and environmental variables, improving the performance of the dairy farm. To obtain values of climatic variables, there are devices known as dataloggers, which are nothing more than electronic devices that record data collected over a period of time, through sensors on its platform and that allow the calculation of thermal comfort indexes. In this work the objective was to improve a datalogger sensor capable of collecting biometeorological data from a dairy farm and transform them into ambience indices, providing the thermal classification of the environment to the producer. For this, a microcontrolled Arduino platform was used, with temperature and relative humidity sensors attached to it. The prototype read the climatic variables providing the values of air temperature, relative humidity, black globe temperature, dew point temperature, THI, BGTHI, TDI and thermal classification of the environment in favorable (comfort), alert (cold and heat) and danger (intense cold, intense heat and unbearable heat), thus responding to the producer's demand and consequently assisting in decision making regarding the appropriate management for the animal and rural worker welfare.
